+
+In the event that fragmentation is required, the incoming payload is split into
+N parts of size ieee->fts. The first fragment contains the SNAP header and the
+remaining packets are just data.
+
+If encryption is enabled, each fragment payload size is reduced by enough space
+to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
+So if you have 1500 bytes of payload with ieee->fts set to 500 without
+encryption it will take 3 frames. With WEP it will take 4 frames as the
+payload of each frame is reduced to 492 bytes.

+ *
+ * FIX:
+ * - there is currently no way of associating TX packets to correct wds device
+ * when TX Exc/OK event occurs, so all tx_packets and some
+ * tx_errors/tx_dropped are added to the main netdevice; using sw_support
+ * field in txdesc might be used to fix this (using Alloc event to increment
+ * tx_packets would need some further info in txfid table)
+ *
+ * Buffer Access Path (BAP) usage:
+ * Prism2 cards have two separate BAPs for accessing the card memory. These
+ * should allow concurrent access to two different frames and the driver
+ * previously used BAP0 for sending data and BAP1 for receiving data.
+ * However, there seems to be number of issues with concurrent access and at
+ * least one know hardware bug in using BAP0 and BAP1 concurrently with PCI
+ * Prism2.5. Therefore, the driver now only uses BAP0 for moving data between
+ * host and card memories. BAP0 accesses are protected with local->baplock
+ * (spin_lock_bh) to prevent concurrent use.

- my3126.c is unused (because t1_my3126_ops isn't used anywhere)
- what are the EXTRA_CFLAGS in drivers/net/chelsio/Makefile for?
- $(cxgb-y) in drivers/net/chelsio/Makefile seems to be unneeded
- completely unused global functions:
- espi.c: t1_espi_get_intr_counts
- sge.c: t1_sge_get_intr_counts
- the following functions can be made static:
- sge.c: t1_espi_workaround
- sge.c: t1_sge_tx
- subr.c: __t1_tpi_read
- subr.c: __t1_tpi_write
- subr.c: t1_wait_op_done
shemminger said:
The performance recommendations in cxgb.txt are common to all fast devices,
and should be in one file rather than just for this device. I would rather
see ip-sysctl.txt updated or a new file on tuning recommendations started.
Some of them have consequences that aren't documented well.
For example, turning off TCP timestamps risks data corruption from sequence wrap.
A new driver shouldn't need so may #ifdef's unless you want to putit on older
vendor versions of 2.4
Some accessor and wrapper functions like:
t1_pci_read_config_4
adapter_name
t1_malloc
are just annoying noise.
Why have useless dead code like:
/* Interrupt handler */
+static int pm3393_interrupt_handler(struct cmac *cmac)
+{
+ u32 master_intr_status;
+/*
+ 1. Read master interrupt register.
+ 2. Read BLOCK's interrupt status registers.
+ 3. Handle BLOCK interrupts.
+*/
Jeff said:
step 1: kill all the OS wrappers.
And do you really need hooks for multiple MACs, when only one MAC is
really supported? Typically these hooks are at a higher level anyway --
struct net_device.
From: Christoph Lameter <christoph@lameter

+ Chelsio N210 10Gb Ethernet Network Controller
+
+ Driver Release Notes for Linux
+
+ Version 2.1.0
+
+ March 8, 2005
+
+CONTENTS
+========
+ INTRODUCTION
+ FEATURES
+ PERFORMANCE
+ DRIVER MESSAGES
+ KNOWN ISSUES
+ SUPPORT
+
+
+INTRODUCTION
+============
+
+ This document describes the Linux driver for Chelsio 10Gb Ethernet Network
+ Controller. This driver supports the Chelsio N210 NIC and is backward
+ compatible with the Chelsio N110 model 10Gb NICs. This driver supports AMD64
+ and EM64T, and x86 systems.
+
+
+FEATURES
+========
+
+ Adaptive Interrupts (adaptive-rx)
+ ---------------------------------
+
+ This feature provides an adaptive algorithm that adjusts the interrupt
+ coalescing parameters, allowing the driver to dynamically adapt the latency
+ settings to achieve the highest performance during various types of network
+ load.
+
+ The interface used to control this feature is ethtool. Please see the
+ ethtool manpage for additional usage information.
+
+ By default, adaptive-rx is disabled.
+ To enable adaptive-rx:
+
+ ethtool -C <interface> adaptive-rx on
+
+ To disable adaptive-rx, use ethtool:
+
+ ethtool -C <interface> adaptive-rx off
+
+ After disabling adaptive-rx, the timer latency value will be set to 50us.
+ You may set the timer latency after disabling adaptive-rx:
+
+ ethtool -C <interface> rx-usecs <microseconds>
+
+ An example to set the timer latency value to 100us on eth0:
+
+ ethtool -C eth0 rx-usecs 100
+
+ You may also provide a timer latency value while disabling adpative-rx:
+
+ ethtool -C <interface> adaptive-rx off rx-usecs <microseconds>
+
+ If adaptive-rx is disabled and a timer latency value is specified, the timer
+ will be set to the specified value until changed by the user or until
+ adaptive-rx is enabled.
+
+ To view the status of the adaptive-rx and timer latency values:
+
+ ethtool -c <interface>
+
+
+ TCP Segmentation Offloading (TSO) Support
+ -----------------------------------------
+
+ This feature, also known as "large send", enables a system's protocol stack
+ to offload portions of outbound TCP processing to a network interface card
+ thereby reducing system CPU utilization and enhancing performance.
+
+ The interface used to control this feature is ethtool version 1.8 or higher.
+ Please see the ethtool manpage for additional usage information.
+
+ By default, TSO is enabled.
+ To disable TSO:
+
+ ethtool -K <interface> tso off
+
+ To enable TSO:
+
+ ethtool -K <interface> tso on
+
+ To view the status of TSO:
+
+ ethtool -k <interface>
+
+
+PERFORMANCE
+===========
+
+ The following information is provided as an example of how to change system
+ parameters for "performance tuning" an what value to use. You may or may not
+ want to change these system parameters, depending on your server/workstation
+ application. Doing so is not warranted in any way by Chelsio Communications,
+ and is done at "YOUR OWN RISK". Chelsio will not be held responsible for loss
+ of data or damage to equipment.
+
+ Your distribution may have a different way of doing things, or you may prefer
+ a different method. These commands are shown only to provide an example of
+ what to do and are by no means definitive.
+
+ Making any of the following system changes will only last until you reboot
+ your system. You may want to write a script that runs at boot-up which
+ includes the optimal settings for your system.
+
+ Setting PCI Latency Timer:
+ setpci -d 1425:* 0x0c.l=0x0000F800
+
+ Disabling TCP timestamp:
+ sysctl -w net.ipv4.tcp_timestamps=0
+
+ Disabling SACK:
+ sysctl -w net.ipv4.tcp_sack=0
+
+ Setting TCP read buffers (min/default/max):
+ sysctl -w net.ipv4.tcp_rmem="10000000 10000000 10000000"
+
+ Setting TCP write buffers (min/pressure/max):
+ sysctl -w net.ipv4.tcp_wmem="10000000 10000000 10000000"
+
+ Setting TCP buffer space (min/pressure/max):
+ sysctl -w net.ipv4.tcp_mem="10000000 10000000 10000000"
+
+ Setting large number of incoming connection requests (2.6.x only):
+ sysctl -w net.ipv4.tcp_max_syn_backlog=3000
+
+ Setting maximum receive socket buffer size:
+ sysctl -w net.core.rmem_max=524287
+
+ Setting maximum send socket buffer size:
+ sysctl -w net.core.wmem_max=524287
+
+ Setting default receive socket buffer size:
+ sysctl -w net.core.rmem_default=524287
+
+ Setting default send socket buffer size:
+ sysctl -w net.core.wmem_default=524287
+
+ Setting maximum option memory buffers:
+ sysctl -w net.core.optmem_max=524287
+
+ Setting maximum backlog (# of unprocessed packets before kernel drops):
+ sysctl -w net.core.netdev_max_backlog=300000
+
+ Set smp_affinity (on a multiprocessor system) to a single CPU:
+ echo 00000001 > /proc/irq/<interrupt_number>/smp_affinity
+
+ TCP window size for single connections:
+ The receive buffer (RX_WINDOW) size must be at least as large as the
+ Bandwidth-Delay Product of the communication link between the sender and
+ receiver. Due to the variations of RTT, you may want to increase the buffer
+ size up to 2 times the Bandwidth-Delay Product. Reference page 289 of
+ "TCP/IP Illustrated, Volume 1, The Protocols" by W. Richard Stevens.
+ At 10Gb speeds, use the following formula:
+ RX_WINDOW >= 1.25MBytes * RTT(in milliseconds)
+ Example for RTT with 100us: RX_WINDOW = (1,250,000 * 0.1) = 125,000
+ RX_WINDOW sizes of 256KB - 512KB should be sufficient.
+ Setting the min, max, and default receive buffer (RX_WINDOW) size:
+ sysctl -w net.ipv4.tcp_rmem="<min> <default> <max>"
+
+ TCP window size for multiple connections:
+ The receive buffer (RX_WINDOW) size may be calculated the same as single
+ connections, but should be divided by the number of connections. The
+ smaller window prevents congestion and facilitates better pacing,
+ especially if/when MAC level flow control does not work well or when it is
+ not supported on the machine. Experimentation may be necessary to attain
+ the correct value. This method is provided as a starting point fot the
+ correct receive buffer size.
+ Setting the min, max, and default receive buffer (RX_WINDOW) size is
+ performed in the same manner as single connection.
+
+

+
+ Link down:
+ eth#: link is down
+
+
+KNOWN ISSUES
+============
+
+ These issues have been identified during testing. The following information
+ is provided as a workaround to the problem. In some cases, this problem is
+ inherent to Linux or to a particular Linux Distribution and/or hardware
+ platform.
+
+ 1. Large number of TCP retransmits on a multiprocessor (SMP) system.
+
+ On a system with multiple CPUs, the interrupt (IRQ) for the network
+ controller may be bound to more than one CPU. This will cause TCP
+ retransmits if the packet data were to be split across different CPUs
+ and re-assembled in a different order than expected.
+
+ To eliminate the TCP retransmits, set smp_affinity on the particular
+ interrupt to a single CPU. You can locate the interrupt (IRQ) used on
+ the N110/N210 by using ifconfig:
+ ifconfig <dev_name> | grep Interrupt
+ Set the smp_affinity to a single CPU:
+ echo 1 > /proc/irq/<interrupt_number>/smp_affinity
+
+ It is highly suggested that you do not run the irqbalance daemon on your
+ system, as this will change any smp_affinity setting you have applied.
+ The irqbalance daemon runs on a 10 second interval and binds interrupts
+ to the least loaded CPU determined by the daemon. To disable this daemon:
+ chkconfig --level 2345 irqbalance off
+
+ By default, some Linux distributions enable the kernel feature,
+ irqbalance, which performs the same function as the daemon. To disable
+ this feature, add the following line to your bootloader:
+ noirqbalance
+
+ Example using the Grub bootloader:
+ title Red Hat Enterprise Linux AS (2.4.21-27.ELsmp)
+ root (hd0,0)
+ kernel /vmlinuz-2.4.21-27.ELsmp ro root=/dev/hda3 noirqbalance
+ initrd /initrd-2.4.21-27.ELsmp.img
+
+ 2. After running insmod, the driver is loaded and the incorrect network
+ interface is brought up without running ifup.
+
+ When using 2.4.x kernels, including RHEL kernels, the Linux kernel
+ invokes a script named "hotplug". This script is primarily used to
+ automatically bring up USB devices when they are plugged in, however,
+ the script also attempts to automatically bring up a network interface
+ after loading the kernel module. The hotplug script does this by scanning
+ the ifcfg-eth# config files in /etc/sysconfig/network-scripts, looking
+ for HWADDR=<mac_address>.
+
+ If the hotplug script does not find the HWADDRR within any of the
+ ifcfg-eth# files, it will bring up the device with the next available
+ interface name. If this interface is already configured for a different
+ network card, your new interface will have incorrect IP address and
+ network settings.
+
+ To solve this issue, you can add the HWADDR=<mac_address> key to the
+ interface config file of your network controller.
+
+ To disable this "hotplug" feature, you may add the driver (module name)
+ to the "blacklist" file located in /etc/hotplug. It has been noted that
+ this does not work for network devices because the net.agent script
+ does not use the blacklist file. Simply remove, or rename, the net.agent
+ script located in /etc/hotplug to disable this feature.
+
+ 3. Transport Protocol (TP) hangs when running heavy multi-connection traffic
+ on an AMD Opteron system with HyperTransport PCI-X Tunnel chipset.
+
+ If your AMD Opteron system uses the AMD-8131 HyperTransport PCI-X Tunnel
+ chipset, you may experience the "133-Mhz Mode Split Completion Data
+ Corruption" bug identified by AMD while using a 133Mhz PCI-X card on the
+ bus PCI-X bus.
+
+ AMD states, "Under highly specific conditions, the AMD-8131 PCI-X Tunnel
+ can provide stale data via split completion cycles to a PCI-X card that
+ is operating at 133 Mhz", causing data corruption.
+
+ AMD's provides three workarounds for this problem, however, Chelsio
+ recommends the first option for best performance with this bug:
+
+ For 133Mhz secondary bus operation, limit the transaction length and
+ the number of outstanding transactions, via BIOS configuration
+ programming of the PCI-X card, to the following:
+
+ Data Length (bytes): 2k
+ Total allowed outstanding transactions: 1
+
+ Please refer to AMD 8131-HT/PCI-X Errata 26310 Rev 3.08 August 2004,
+ section 56, "133-MHz Mode Split Completion Data Corruption" for more
+ details with this bug and workarounds suggested by AMD.

+ * XAUI_ARESETB - XAUI bus analog circuitry

+ * 1. Assert RSTB pin low ( write 0 )
+ * 2. Wait at least 1ms to initiate a complete initialization of device.
+ * 3. Wait until all external clocks and REFSEL are stable.
+ * 4. Wait minimum of 1ms. (after external clocks and REFEL are stable)
+ * 5. De-assert RSTB ( write 1 )
+ * 6. Wait until internal timers to expires after ~14ms.
+ * - Allows analog clock synthesizer(PL4CSU) to stabilize to
+ * selected reference frequency before allowing the digital
+ * portion of the device to operate.
+ * 7. Wait at least 200us for XAUI interface to stabilize.
+ * 8. Verify the PM3393 came out of reset successfully.
+ * Set successful reset flag if everything worked else try again
+ * a few more times.

+===========================
+Intel(R) PRO/Wireless 2100 Network Connection Driver for Linux
+README.ipw2100
+
+March 14, 2005
+
+===========================
+Index
+---------------------------
+0. Introduction
+1. Release 1.1.0 Current Features
+2. Command Line Parameters
+3. Sysfs Helper Files
+4. Radio Kill Switch
+5. Dynamic Firmware
+6. Power Management
+7. Support
+8. License
+
+
+===========================
+0. Introduction
+------------ ----- ----- ---- --- -- -
+
+This document provides a brief overview of the features supported by the
+IPW2100 driver project. The main project website, where the latest
+development version of the driver can be found, is:
+
+ http://ipw2100.sourceforge.net
+
+There you can find the not only the latest releases, but also information about
+potential fixes and patches, as well as links to the development mailing list
+for the driver project.
+
+
+===========================
+1. Release 1.1.0 Current Supported Features
+---------------------------
+- Managed (BSS) and Ad-Hoc (IBSS)
+- WEP (shared key and open)
+- Wireless Tools support
+- 802.1x (tested with XSupplicant 1.0.1)
+
+Enabled (but not supported) features:
+- Monitor/RFMon mode
+- WPA/WPA2
+
+The distinction between officially supported and enabled is a reflection
+on the amount of validation and interoperability testing that has been
+performed on a given feature.
+
+
+===========================
+2. Command Line Parameters
+---------------------------
+
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax:
+
+ modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
+
+For example, to disable the radio on driver loading, enter:
+
+ modprobe ipw2100 disable=1
+
+The ipw2100 driver supports the following module parameters:
+
+Name Value Example:
+debug 0x0-0xffffffff debug=1024
+mode 0,1,2 mode=1 /* AdHoc */
+channel int channel=3 /* Only valid in AdHoc or Monitor */
+associate boolean associate=0 /* Do NOT auto associate */
+disable boolean disable=1 /* Do not power the HW */
+
+
+===========================
+3. Sysfs Helper Files
+---------------------------
+
+There are several ways to control the behavior of the driver. Many of the
+general capabilities are exposed through the Wireless Tools (iwconfig). There
+are a few capabilities that are exposed through entries in the Linux Sysfs.
+
+
+----- Driver Level ------
+For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
+
+ debug_level
+
+ This controls the same global as the 'debug' module parameter. For
+ information on the various debugging levels available, run the 'dvals'
+ script found in the driver source directory.
+
+ NOTE: 'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn
+ on.
+
+----- Device Level ------
+For the device level files look in
+
+ /sys/bus/pci/drivers/ipw2100/{PCI-ID}/
+
+For example:
+ /sys/bus/pci/drivers/ipw2100/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/drivers/ipw2100:
+
+ rf_kill
+ read -
+ 0 = RF kill not enabled (radio on)
+ 1 = SW based RF kill active (radio off)
+ 2 = HW based RF kill active (radio off)
+ 3 = Both HW and SW RF kill active (radio off)
+ write -
+ 0 = If SW based RF kill active, turn the radio back on
+ 1 = If radio is on, activate SW based RF kill
+
+ NOTE: If you enable the SW based RF kill and then toggle the HW
+ based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+
+
+===========================
+4. Radio Kill Switch
+---------------------------
+Most laptops provide the ability for the user to physically disable the radio.
+Some vendors have implemented this as a physical switch that requires no
+software to turn the radio off and on. On other laptops, however, the switch
+is controlled through a button being pressed and a software driver then making
+calls to turn the radio off and on. This is referred to as a "software based
+RF kill switch"
+
+See the Sysfs helper file 'rf_kill' for determining the state of the RF switch
+on your system.
+
+
+===========================
+5. Dynamic Firmware
+---------------------------
+As the firmware is licensed under a restricted use license, it can not be
+included within the kernel sources. To enable the IPW2100 you will need a
+firmware image to load into the wireless NIC's processors.
+
+You can obtain these images from <http://ipw2100.sf.net/firmware.php>.
+
+See INSTALL for instructions on installing the firmware.
+
+
+===========================
+6. Power Management
+---------------------------
+The IPW2100 supports the configuration of the Power Save Protocol
+through a private wireless extension interface. The IPW2100 supports
+the following different modes:
+
+ off No power management. Radio is always on.
+ on Automatic power management
+ 1-5 Different levels of power management. The higher the
+ number the greater the power savings, but with an impact to
+ packet latencies.
+
+Power management works by powering down the radio after a certain
+interval of time has passed where no packets are passed through the
+radio. Once powered down, the radio remains in that state for a given
+period of time. For higher power savings, the interval between last
+packet processed to sleep is shorter and the sleep period is longer.
+
+When the radio is asleep, the access point sending data to the station
+must buffer packets at the AP until the station wakes up and requests
+any buffered packets. If you have an AP that does not correctly support
+the PSP protocol you may experience packet loss or very poor performance
+while power management is enabled. If this is the case, you will need
+to try and find a firmware update for your AP, or disable power
+management (via `iwconfig eth1 power off`)
+
+To configure the power level on the IPW2100 you use a combination of
+iwconfig and iwpriv. iwconfig is used to turn power management on, off,
+and set it to auto.
+
+ iwconfig eth1 power off Disables radio power down
+ iwconfig eth1 power on Enables radio power management to
+ last set level (defaults to AUTO)
+ iwpriv eth1 set_power 0 Sets power level to AUTO and enables
+ power management if not previously
+ enabled.
+ iwpriv eth1 set_power 1-5 Set the power level as specified,
+ enabling power management if not
+ previously enabled.
+
+You can view the current power level setting via:
+
+ iwpriv eth1 get_power
+
+It will return the current period or timeout that is configured as a string
+in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
+time after packet processing), yyyy is the period to sleep (amount of time to
+wait before powering the radio and querying the access point for buffered
+packets), and z is the 'power level'. If power management is turned off the
+xxxx/yyyy will be replaced with 'off' -- the level reported will be the active
+level if `iwconfig eth1 power on` is invoked.
+
+
+===========================
+7. Support

+
+ In order to use this driver, you will need a firmware image for it.
+ You can obtain the firmware from
+ <http://ipw2100.sf.net/>. Once you have the firmware image, you
+ will need to place it in /etc/firmware.
+
+ You will also very likely need the Wireless Tools in order to
+ configure your card:
+
+ <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
+
+ If you want to compile the driver as a module ( = code which can be

+ will be called ipw2100.ko.

+ This will result in the kernel module being ~60k larger. You can
+ control which debug output is sent to the kernel log by setting the
+ value in
+
+ /sys/bus/pci/drivers/ipw2100/debug_level
+
+ This entry will only exist if this option is enabled.
+
+ If you are not trying to debug or develop the IPW2100 driver, you

+ Maciej Urbaniak, and Maciej Sosnowski.
+
+ Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak.
+
+Theory of Operation
+
+Tx - Commands and Data
+
+Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs)
+Each TBD contains a pointer to the physical (dma_addr_t) address of data being
+sent to the firmware as well as the length of the data.
+
+The host writes to the TBD queue at the WRITE index. The WRITE index points
+to the _next_ packet to be written and is advanced when after the TBD has been
+filled.
+
+The firmware pulls from the TBD queue at the READ index. The READ index points
+to the currently being read entry, and is advanced once the firmware is
+done with a packet.
+
+When data is sent to the firmware, the first TBD is used to indicate to the
+firmware if a Command or Data is being sent. If it is Command, all of the
+command information is contained within the physical address referred to by the
+TBD. If it is Data, the first TBD indicates the type of data packet, number
+of fragments, etc. The next TBD then referrs to the actual packet location.
+
+The Tx flow cycle is as follows:
+
+1) ipw2100_tx() is called by kernel with SKB to transmit
+2) Packet is move from the tx_free_list and appended to the transmit pending
+ list (tx_pend_list)
+3) work is scheduled to move pending packets into the shared circular queue.
+4) when placing packet in the circular queue, the incoming SKB is DMA mapped
+ to a physical address. That address is entered into a TBD. Two TBDs are
+ filled out. The first indicating a data packet, the second referring to the
+ actual payload data.
+5) the packet is removed from tx_pend_list and placed on the end of the
+ firmware pending list (fw_pend_list)
+6) firmware is notified that the WRITE index has
+7) Once the firmware has processed the TBD, INTA is triggered.
+8) For each Tx interrupt received from the firmware, the READ index is checked
+ to see which TBDs are done being processed.
+9) For each TBD that has been processed, the ISR pulls the oldest packet
+ from the fw_pend_list.
+10)The packet structure contained in the fw_pend_list is then used
+ to unmap the DMA address and to free the SKB originally passed to the driver
+ from the kernel.
+11)The packet structure is placed onto the tx_free_list
+
+The above steps are the same for commands, only the msg_free_list/msg_pend_list
+are used instead of tx_free_list/tx_pend_list
+
+...
+
+Critical Sections / Locking :
+
+There are two locks utilized. The first is the low level lock (priv->low_lock)
+that protects the following:
+
+- Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows:
+
+ tx_free_list : Holds pre-allocated Tx buffers.
+ TAIL modified in __ipw2100_tx_process()
+ HEAD modified in ipw2100_tx()
+
+ tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring
+ TAIL modified ipw2100_tx()
+ HEAD modified by X__ipw2100_tx_send_data()
+
+ msg_free_list : Holds pre-allocated Msg (Command) buffers
+ TAIL modified in __ipw2100_tx_process()
+ HEAD modified in ipw2100_hw_send_command()
+
+ msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring
+ TAIL modified in ipw2100_hw_send_command()
+ HEAD modified in X__ipw2100_tx_send_commands()
+
+ The flow of data on the TX side is as follows:
+
+ MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST
+ TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST
+
+ The methods that work on the TBD ring are protected via priv->low_lock.
+
+- The internal data state of the device itself
+- Access to the firmware read/write indexes for the BD queues
+ and associated logic
+
+All external entry functions are locked with the priv->action_lock to ensure
+that only one external action is invoked at a time.

+
+1. Introduction
+-----------------------------------------------
+The following sections attempt to provide a brief introduction to using
+the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
+
+This document is not meant to be a comprehensive manual on
+understanding or using wireless technologies, but should be sufficient
+to get you moving without wires on Linux.
+
+For information on building and installing the driver, see the INSTALL
+file.
+
+
+1.1. Overview of Features
+-----------------------------------------------
+The current release (1.0.0) supports the following features:
+
++ BSS mode (Infrastructure, Managed)
++ IBSS mode (Ad-Hoc)
++ WEP (OPEN and SHARED KEY mode)
++ 802.1x EAP via wpa_supplicant and xsupplicant
++ Wireless Extension support
++ Full B and G rate support (2200 and 2915)
++ Full A rate support (2915 only)
++ Transmit power control
++ S state support (ACPI suspend/resume)
++ long/short preamble support
+
+
+
+1.2. Command Line Parameters
+-----------------------------------------------
+
+Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless
+2915ABG Driver for Linux allows certain configuration options to be
+provided as module parameters. The most common way to specify a module
+parameter is via the command line.
+
+The general form is:
+
+% modprobe ipw2200 parameter=value
+
+Where the supported parameter are:
+
+ associate
+ Set to 0 to disable the auto scan-and-associate functionality of the
+ driver. If disabled, the driver will not attempt to scan
+ for and associate to a network until it has been configured with
+ one or more properties for the target network, for example configuring
+ the network SSID. Default is 1 (auto-associate)
+
+ Example: % modprobe ipw2200 associate=0
+
+ auto_create
+ Set to 0 to disable the auto creation of an Ad-Hoc network
+ matching the channel and network name parameters provided.
+ Default is 1.
+
+ channel
+ channel number for association. The normal method for setting
+ the channel would be to use the standard wireless tools
+ (i.e. `iwconfig eth1 channel 10`), but it is useful sometimes
+ to set this while debugging. Channel 0 means 'ANY'
+
+ debug
+ If using a debug build, this is used to control the amount of debug
+ info is logged. See the 'dval' and 'load' script for more info on
+ how to use this (the dval and load scripts are provided as part
+ of the ipw2200 development snapshot releases available from the
+ SourceForge project at http://ipw2200.sf.net)
+
+ mode
+ Can be used to set the default mode of the adapter.
+ 0 = Managed, 1 = Ad-Hoc
+
+
+1.3. Wireless Extension Private Methods
+-----------------------------------------------
+
+As an interface designed to handle generic hardware, there are certain
+capabilities not exposed through the normal Wireless Tool interface. As
+such, a provision is provided for a driver to declare custom, or
+private, methods. The Intel(R) PRO/Wireless 2915ABG Driver for Linux
+defines several of these to configure various settings.
+
+The general form of using the private wireless methods is:
+
+ % iwpriv $IFNAME method parameters
+
+Where $IFNAME is the interface name the device is registered with
+(typically eth1, customized via one of the various network interface
+name managers, such as ifrename)
+
+The supported private methods are:
+
+ get_mode
+ Can be used to report out which IEEE mode the driver is
+ configured to support. Example:
+
+ % iwpriv eth1 get_mode
+ eth1 get_mode:802.11bg (6)
+
+ set_mode
+ Can be used to configure which IEEE mode the driver will
+ support.
+
+ Usage:
+ % iwpriv eth1 set_mode {mode}
+ Where {mode} is a number in the range 1-7:
+ 1 802.11a (2915 only)
+ 2 802.11b
+ 3 802.11ab (2915 only)
+ 4 802.11g
+ 5 802.11ag (2915 only)
+ 6 802.11bg
+ 7 802.11abg (2915 only)
+
+ get_preamble
+ Can be used to report configuration of preamble length.
+
+ set_preamble
+ Can be used to set the configuration of preamble length:
+
+ Usage:
+ % iwpriv eth1 set_preamble {mode}
+ Where {mode} is one of:
+ 1 Long preamble only
+ 0 Auto (long or short based on connection)
+
+
+1.4. Sysfs Helper Files:
+-----------------------------------------------
+
+The Linux kernel provides a pseudo file system that can be used to
+access various components of the operating system. The Intel(R)
+PRO/Wireless 2915ABG Driver for Linux exposes several configuration
+parameters through this mechanism.
+
+An entry in the sysfs can support reading and/or writing. You can
+typically query the contents of a sysfs entry through the use of cat,
+and can set the contents via echo. For example:
+
+% cat /sys/bus/pci/drivers/ipw2200/debug_level
+
+Will report the current debug level of the driver's logging subsystem
+(only available if CONFIG_IPW_DEBUG was configured when the driver was
+built).
+
+You can set the debug level via:
+
+% echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
+
+Where $VALUE would be a number in the case of this sysfs entry. The
+input to sysfs files does not have to be a number. For example, the
+firmware loader used by hotplug utilizes sysfs entries for transferring
+the firmware image from user space into the driver.
+
+The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries
+at two levels -- driver level, which apply to all instances of the
+driver (in the event that there are more than one device installed) and
+device level, which applies only to the single specific instance.
+
+
+1.4.1 Driver Level Sysfs Helper Files
+-----------------------------------------------
+
+For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
+
+ debug_level
+
+ This controls the same global as the 'debug' module parameter
+
+
+1.4.2 Device Level Sysfs Helper Files
+-----------------------------------------------
+
+For the device level files, look in
+
+ /sys/bus/pci/drivers/ipw2200/{PCI-ID}/
+
+For example:
+ /sys/bus/pci/drivers/ipw2200/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/[drivers/ipw2200:
+
+ rf_kill
+ read -
+ 0 = RF kill not enabled (radio on)
+ 1 = SW based RF kill active (radio off)
+ 2 = HW based RF kill active (radio off)
+ 3 = Both HW and SW RF kill active (radio off)
+ write -
+ 0 = If SW based RF kill active, turn the radio back on
+ 1 = If radio is on, activate SW based RF kill
+
+ NOTE: If you enable the SW based RF kill and then toggle the HW
+ based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+
+ ucode
+ read-only access to the ucode version number
+
+
+2. About the Version Numbers
+-----------------------------------------------
+
+Due to the nature of open source development projects, there are
+frequently changes being incorporated that have not gone through
+a complete validation process. These changes are incorporated into
+development snapshot releases.
+
+Releases are numbered with a three level scheme:
+
+ major.minor.development
+
+Any version where the 'development' portion is 0 (for example
+1.0.0, 1.1.0, etc.) indicates a stable version that will be made
+available for kernel inclusion.
+
+Any version where the 'development' portion is not a 0 (for
+example 1.0.1, 1.1.5, etc.) indicates a development version that is
+being made available for testing and cutting edge users. The stability
+and functionality of the development releases are not know. We make
+efforts to try and keep all snapshots reasonably stable, but due to the
+frequency of their release, and the desire to get those releases
+available as quickly as possible, unknown anomalies should be expected.
+
+The major version number will be incremented when significant changes
+are made to the driver. Currently, there are no major changes planned.
+
+
+3. Support

+For installation support of the 1.0.0 version, you can contact
+http://supportmail.intel.com, or you can use the open source project
+support.

+ * Rx theory of operation
+ *
+ * The host allocates 32 DMA target addresses and passes the host address
+ * to the firmware at register CX2_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
+ * 0 to 31
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two index registers for managing the Rx buffers.
+ *
+ * The READ index maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ index is managed by the firmware once the card is enabled.
+ *
+ * The WRITE index maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization the host sets up the READ queue position to the first
+ * INDEX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer it will advance the READ index
+ * and fire the RX interrupt. The driver can then query the READ index and
+ * process as many packets as possible, moving the WRITE index forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
+ * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ * to replensish the ipw->rxq->rx_free.
+ * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
+ * ipw->rxq is replenished and the READ INDEX is updated (updating the
+ * 'processed' and 'read' driver indexes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ * detached from the ipw->rxq. The driver 'processed' index is updated.
+ * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
+ * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
+ * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
+ * were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * ipw_rx_queue_alloc() Allocates rx_free
+ * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
+ * ipw_rx_queue_restock
+ * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
+ * queue, updates firmware pointers, and updates
+ * the WRITE index. If insufficient rx_free buffers
+ * are available, schedules ipw_rx_queue_replenish
+ *
+ * -- enable interrupts --
+ * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
+ * READ INDEX, detaching the SKB from the pool.
+ * Moves the packet buffer from queue to rx_used.
+ * Calls ipw_rx_queue_restock to refill any empty
+ * slots.

If you select something, you have to ensure that the dependencies
of what you do select are fulfilled.
resulting in the following compile error:

This patch adds the missing selects of CRYPTO (similar to how
IEEE80211_CRYPT_WEP already does it).
Yes, you could argue whether CRYPTO should be select'ed by the CRYPTO_*
options, but with the current CRYPTO* dependencies this patch is
required.

Subject: [PATCH 014/997] [PATCH] ieee80211: remove pci.h #include's
I was wondering why editing pci.h triggered the rebuild of three files
under net/, and as far as I can see, there's no reason for these three
files to #include pci.h .

Subject: [PATCH 015/997] [PATCH] ieee80211: fix recursive ipw2200 dependencies
This results in recursive dependencies:
- IPW2200 depends on NET_RADIO
- IPW2200 selects IEEE80211
- IEEE80211 selects NET_RADIO
This patch fixes the IPW2200 dependencies in a way that they are similar
to the IPW2100 dependencies.

Subject: [PATCH 018/997] [PATCH] drivers/net/wireless/ipw2100: Use the
DMA_32BIT_MASK constant
Use the DMA_32BIT_MASK constant from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask() instead of custom macros.
This patch includes dma-mapping.h explicitly because it caused errors on some
architectures otherwise. See

Subject: [PATCH 025/997] [PATCH] wireless-device-attr-fixes-2
More fixes for greg depredations.

Subject: [PATCH 028/997] drm: add framebuffer maps
The patch makes drmAddBufs/drmMapBufs can handle buffers in video memory
The attached patch adds a new buffer type DRM_FB_BUFFER. It works like
AGP memory but uses video memory.

Subject: [PATCH 035/997] drm: add test for AGP devices and driver override for
it.
Added device_is_agp callback to drm_driver. This function is called by the
platform-specific drm_device_is_agp function. Added implementation of this
function the the Linux-specific portion of the MGA driver to detect PCI G450
cards. Added code to the Linux-specific portion of the generic DRM layer to
not initialize AGP infrastructure if the card is not AGP (this matches what
already existed in BSD).
Fix up i810/i830 and i915 drivers to always return AGP as they don't always
report the capability.
Fix the MGA to not report AGP for a card that has an AGP chip behind a PCI
bridge.

Subject: [PATCH 038/997] Add support for PCI MGA cards to MGA DRM.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds serveral new ioctls and a new query to get_param query to
support PCI MGA cards.
Two ioctls were added to implement interrupt based waiting. With this change,
the client-side driver no longer needs to map the primary DMA region or the
MMIO region. Previously, end-of-frame waiting was done by busy waiting in the
client-side driver until one of the MMIO registers (the current DMA pointer)
matched a pointer to the end of primary DMA space. By using interrupts, the
busy waiting and the extra mappings are removed.
A third ioctl was added to bootstrap DMA. This ioctl, which is used by the
X-server, moves a *LOT* of code from the X-server into the kernel. This allows
the kernel to do whatever needs to be done to setup DMA buffers. The entire
process and the locations of the buffers are hidden from user-mode.
Additionally, a get_param query was added to differentiate between G4x0 cards
and G550 cards. A gap was left in the numbering sequence so that, if needed,
G450 cards could be distinguished from G400 cards. According to Ville
Syrjälä, the G4x0 cards and the G550 cards handle anisotropic filtering
differently. This seems the most compatible way to let the client-side driver
know which card it's own. Doing this very small change now eliminates the
need to bump the DRM minor version twice.
http://marc.theaimsgroup.com/?l=dri-devel&m=106625815319773&w=2
(airlied - this may not work at this point, I think the follow on buffer
cleanup patches will be needed)

Subject: [PATCH 040/997] drm: cleanup buffer/map code
This is a patch from DRM CVS that cleans up some code that was in CVS
that I never moved to the kernel, this patch produces the result of the
cleanups and puts it into the kernel drm.

Subject: [PATCH 044/997] [SERIAL] Pass around serial_private instead of
pci_dev
Pass the serial_private structure via the setup method instead of
the pci_dev. We don't want to assume that the pci_dev's driver
data is a pointer to serial_private. Instead, put the pci_dev
inside serial_private.

Subject: [PATCH 045/997] [SERIAL] Expose 8250_pci setup/removal/suspend/resume
functions
Re-jig the setup/removal/suspend/resume of 8250 pci ports so that they
know slightly less about how they're attached to a PCI device. Expose
this as the new interface for registering PCI serial ports, as well as
the pciserial_board structure and associated flag definitions.

Subject: [PATCH 046/997] [SERIAL] Convert parport_serial to use new 8250_pci
interfaces
Convert parport_serial to use the new 8250_pci interface, converting
the table to a pciserial_board table. This also unuses the SPCI_*
definitions in serialP.h, which can now be removed.

From cbc3d65ebcb0c494183d45cf202a53352cbf3871 Mon Sep 17 00:00:00 2001
From: Dave Kleikamp <shaggy@austin.ibm.com>
Date: Wed, 27 Jul 2005 09:17:57 -0500
Subject: [PATCH 047/997] JFS: Improve sync barrier processing
Under heavy load, hot metadata pages are often locked by non-committed
transactions, making them difficult to flush to disk. This prevents
the sync point from advancing past a transaction that had modified the
page.
There is a point during the sync barrier processing where all
outstanding transactions have been committed to disk, but no new
transaction have been allowed to proceed. This is the best time
to write the metadata.

Subject: [PATCH 048/997] [netdrvr] add 'uli526x' driver (a tulip clone)
We want to extract our LAN card driver from tulip core driver and
make a new file uli526x.c at tulip folder, because we have added
some ethtool interface support and non-eprom support in our driver
and may be other change in the futher.
If our controllers support are still contained in the tulip core
driver, I think it'll increase the complexity of maintenance, you
know, tulip core driver include several files and support so many
other controllers. Furthermore, I tested the newest kernel 2.6.12
and I found the tulip driver can not work on our lan controller, and
I no time to debug it, so I aspired want to make a single uli526x.c
file just for our controllers. Could you help us remove the ULi
m5261/m5263 lan controller support from tulip core driver and add
the new single uli526x.c file for us?

Subject: [PATCH 052/997] [PATCH] hostap update
Create sysfs "device" files for hostap
I was writing some scripts to automatically build kismet source lines,
and I noticed that hostap devices don't have device files, unlike my
prism54 and ipw2200 cards:
$ ls -l /sys/class/net/eth0/device
/sys/class/net/eth0/device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:02:01.0
$ ls -l /sys/class/net/wifi0
ls: /sys/class/net/wifi0/device: No such file or directory
$ ls -l /sys/class/net/wlan0
ls: /sys/class/net/wlan0/device: No such file or directory
The following (quite small) patch makes sure that both the wlan and wifi
net devices have that pointer to the bus device.
This way, I can do things like
for i in /sys/class/net/*; do
if ! [ -e $i/device/drive ]; then
continue;
fi;
driver=$(basename $(readlink $i/device/driver))
case $driver in
hostap*)
echo -- hostap,$i,$i-$driver
break;
ipw2?00)
echo -- $driver,$i,$i-$driver
break;
prism54)
echo prism54g,$i
esac
done
Which should generate a working set of source lines for kismet no matter
what order I plug the cards in.
It might also be handy to have a link between the two net devices, but
that's a patch for another day.
That patch is against 2.6.13-rc1-mm1.

Subject: [PATCH 053/997] [PATCH] hostap update
pcmcia id_table for hostap_cs.c
Hi Jouni,
Here's a patch for adding a pcmcia id_table to hostap_cs.c as introduced
by the PCMCIA subsystem changes in linux-2.6.13-rc1. The id_table allows
hotplug (along with pcmciautils [1]) to load the driver without the need
for the pcmcia-cs cardmgr daemon.
The id_table was generated from the CVS version of hostap_cs.conf using
a script borrowed from Dominik Brodowski. I have removed any duplicate
entries, but I have only been able to test the functionality of the
patch with a Linksys WPC11v3.
Sincerely,
Brix

Subject: [PATCH 056/997] [PATCH] hostap update
Cleaned up scan result processing by converting struct
hfa384x_scan_result into struct hfa384x_hostscan_result. This removes
special cases from result processing since the results are only used
in one, hostscan, format.

Subject: [PATCH 057/997] [PATCH] hostap update
Firmware seems to be getting into odd state in host_roaming mode 2
when hostscan is used without join command, so try to fix this by
re-joining the current AP. This does not actually trigger a new
association if the current AP is still in the scan results.
This makes background scans (iwlist wlan0 scan) not to break data
connection when in host_roaming 2 mode, e.g., when using wpa_supplicant.

Subject: [PATCH 059/997] [PATCH] hostap update
Warning fix for 64-bit platforms
Hello!
The patch fixes following warning seen on 64-bit platforms (in my case -
x86_64, gcc-4.0):
In file included from /usr/local/src/hostap/driver/modules/hostap_cs.c:203:
/usr/local/src/hostap/driver/modules/hostap_hw.c: In function ?prism2_transmit_cb?:
/usr/local/src/hostap/driver/modules/hostap_hw.c:1674: warning: cast from pointer to integer of different size
/usr/local/src/hostap/driver/modules/hostap_hw.c: In function ?prism2_transmit?:
/usr/local/src/hostap/driver/modules/hostap_hw.c:1758: warning: cast to pointer from integer of different size
prism2_transmit_cb uses a (void *) argument to get an integer. A
simple fix would be to use double cast from pointer to long and then to
int (and vice versa when int is passed as a pointer). But I prefer a
slightly longer patch.
I believe that whenever an argument can hold both a pointer and an
integer, it should be declared long. long can hold both pointers and
integers (except win64, but we are not coding for Windows), it can be
cast to both of them and it's never assumed to be a valid pointer, which
could be useful for some automatic code checkers.

Subject: [PATCH 061/997] [PATCH] sis190: resurrection
Raise the sis190 driver from the dead
The driver handles the integrated network device found on SiS 965L
chipset. It follows the classical (non-napi) interrupt-driven model
and provides minimal ethtool support.
The code comes from a heavy cleanup/rewrite of the original code
which was removed from the kernel on 14/04/2004. Since the r8169
driver does not work too bad and there will probably be (at least)
a few months of improvements/testing/fixing, I made the code as
close as possible to the r8169 one.
Pascal Chapperon <pascal.chapperon@wanadoo.fr> deserves some special
credit for testing and bug-catching. Many thanks to Lars Vahlenberg
as well.

Subject: [PATCH 063/997] [PATCH] sis190: ethtool/mii support.
ethtool/mii support
Bug: disabling autonegotiation and setting the link parameters at the
same time does not provide the expected result. More investigation is
needed.
Note: past the initial probe/open time, the link is managed from user-space
or accessed through sis190_phy_task, i.e. in a usermode context. Whence the
very limited locking needs.

Extract some mac addr code from SiS's driver.
Some magic may hide beyond the isa bridge. The Rx mac control
register is now set without condition.
Note: good or bad, this part of the code is quite close to sis900.c.

Subject: [PATCH 068/997] [PATCH] sis190: the size of the Rx buffer is
constrained
Add a restriction to the size of the Rx buffer
SiS driver forces the size of any Rx buffer to be a multiple of 64 bit.
I would not be surprized that it goes along with some alignment issues
which have been experienced before. So far it does not make much of a
difference (both drivers use 1536 bytes buffer).

Subject: [PATCH 075/997] [PATCH] sis190: compare the lpa to the local
advertisement
The station control register must depend on both the advertisement and the lpa
The link partner ability has better be intersected with the current
advertised value before it is feed to the station control register.

+PHY Abstraction Layer
+(Updated 2005-07-21)
+
+Purpose
+
+ Most network devices consist of set of registers which provide an interface
+ to a MAC layer, which communicates with the physical connection through a
+ PHY. The PHY concerns itself with negotiating link parameters with the link
+ partner on the other side of the network connection (typically, an ethernet
+ cable), and provides a register interface to allow drivers to determine what
+ settings were chosen, and to configure what settings are allowed.
+
+ While these devices are distinct from the network devices, and conform to a
+ standard layout for the registers, it has been common practice to integrate
+ the PHY management code with the network driver. This has resulted in large
+ amounts of redundant code. Also, on embedded systems with multiple (and
+ sometimes quite different) ethernet controllers connected to the same
+ management bus, it is difficult to ensure safe use of the bus.
+
+ Since the PHYs are devices, and the management busses through which they are
+ accessed are, in fact, busses, the PHY Abstraction Layer treats them as such.
+ In doing so, it has these goals:
+
+ 1) Increase code-reuse
+ 2) Increase overall code-maintainability
+ 3) Speed development time for new network drivers, and for new systems
+
+ Basically, this layer is meant to provide an interface to PHY devices which
+ allows network driver writers to write as little code as possible, while
+ still providing a full feature set.
+
+The MDIO bus
+
+ Most network devices are connected to a PHY by means of a management bus.
+ Different devices use different busses (though some share common interfaces).
+ In order to take advantage of the PAL, each bus interface needs to be
+ registered as a distinct device.
+
+ 1) read and write functions must be implemented. Their prototypes are:
+
+ int write(struct mii_bus *bus, int mii_id, int regnum, u16 value);
+ int read(struct mii_bus *bus, int mii_id, int regnum);
+
+ mii_id is the address on the bus for the PHY, and regnum is the register
+ number. These functions are guaranteed not to be called from interrupt
+ time, so it is safe for them to block, waiting for an interrupt to signal
+ the operation is complete
+
+ 2) A reset function is necessary. This is used to return the bus to an
+ initialized state.
+
+ 3) A probe function is needed. This function should set up anything the bus
+ driver needs, setup the mii_bus structure, and register with the PAL using
+ mdiobus_register. Similarly, there's a remove function to undo all of
+ that (use mdiobus_unregister).
+
+ 4) Like any driver, the device_driver structure must be configured, and init
+ exit functions are used to register the driver.
+
+ 5) The bus must also be declared somewhere as a device, and registered.
+
+ As an example for how one driver implemented an mdio bus driver, see
+ drivers/net/gianfar_mii.c and arch/ppc/syslib/mpc85xx_devices.c
+
+Connecting to a PHY
+
+ Sometime during startup, the network driver needs to establish a connection
+ between the PHY device, and the network device. At this time, the PHY's bus
+ and drivers need to all have been loaded, so it is ready for the connection.
+ At this point, there are several ways to connect to the PHY:
+
+ 1) The PAL handles everything, and only calls the network driver when
+ the link state changes, so it can react.
+
+ 2) The PAL handles everything except interrupts (usually because the
+ controller has the interrupt registers).
+
+ 3) The PAL handles everything, but checks in with the driver every second,
+ allowing the network driver to react first to any changes before the PAL
+ does.
+
+ 4) The PAL serves only as a library of functions, with the network device
+ manually calling functions to update status, and configure the PHY
+
+
+Letting the PHY Abstraction Layer do Everything
+
+ If you choose option 1 (The hope is that every driver can, but to still be
+ useful to drivers that can't), connecting to the PHY is simple:
+
+ First, you need a function to react to changes in the link state. This
+ function follows this protocol:
+
+ static void adjust_link(struct net_device *dev);
+
+ Next, you need to know the device name of the PHY connected to this device.
+ The name will look something like, "phy0:0", where the first number is the
+ bus id, and the second is the PHY's address on that bus.
+
+ Now, to connect, just call this function:
+
+ phydev = phy_connect(dev, phy_name, &adjust_link, flags);
+
+ phydev is a pointer to the phy_device structure which represents the PHY. If
+ phy_connect is successful, it will return the pointer. dev, here, is the
+ pointer to your net_device. Once done, this function will have started the
+ PHY's software state machine, and registered for the PHY's interrupt, if it
+ has one. The phydev structure will be populated with information about the
+ current state, though the PHY will not yet be truly operational at this
+ point.
+
+ flags is a u32 which can optionally contain phy-specific flags.
+ This is useful if the system has put hardware restrictions on
+ the PHY/controller, of which the PHY needs to be aware.
+
+ Now just make sure that phydev->supported and phydev->advertising have any
+ values pruned from them which don't make sense for your controller (a 10/100
+ controller may be connected to a gigabit capable PHY, so you would need to
+ mask off SUPPORTED_1000baseT*). See include/linux/ethtool.h for definitions
+ for these bitfields. Note that you should not SET any bits, or the PHY may
+ get put into an unsupported state.
+
+ Lastly, once the controller is ready to handle network traffic, you call
+ phy_start(phydev). This tells the PAL that you are ready, and configures the
+ PHY to connect to the network. If you want to handle your own interrupts,
+ just set phydev->irq to PHY_IGNORE_INTERRUPT before you call phy_start.
+ Similarly, if you don't want to use interrupts, set phydev->irq to PHY_POLL.
+
+ When you want to disconnect from the network (even if just briefly), you call
+ phy_stop(phydev).
+
+Keeping Close Tabs on the PAL
+
+ It is possible that the PAL's built-in state machine needs a little help to
+ keep your network device and the PHY properly in sync. If so, you can
+ register a helper function when connecting to the PHY, which will be called
+ every second before the state machine reacts to any changes. To do this, you
+ need to manually call phy_attach() and phy_prepare_link(), and then call
+ phy_start_machine() with the second argument set to point to your special
+ handler.
+
+ Currently there are no examples of how to use this functionality, and testing
+ on it has been limited because the author does not have any drivers which use
+ it (they all use option 1). So Caveat Emptor.
+
+Doing it all yourself
+
+ There's a remote chance that the PAL's built-in state machine cannot track
+ the complex interactions between the PHY and your network device. If this is
+ so, you can simply call phy_attach(), and not call phy_start_machine or
+ phy_prepare_link(). This will mean that phydev->state is entirely yours to
+ handle (phy_start and phy_stop toggle between some of the states, so you
+ might need to avoid them).
+
+ An effort has been made to make sure that useful functionality can be
+ accessed without the state-machine running, and most of these functions are
+ descended from functions which did not interact with a complex state-machine.
+ However, again, no effort has been made so far to test running without the
+ state machine, so tryer beware.
+
+ Here is a brief rundown of the functions:
+
+ int phy_read(struct phy_device *phydev, u16 regnum);
+ int phy_write(struct phy_device *phydev, u16 regnum, u16 val);
+
+ Simple read/write primitives. They invoke the bus's read/write function
+ pointers.
+
+ void phy_print_status(struct phy_device *phydev);
+
+ A convenience function to print out the PHY status neatly.
+
+ int phy_clear_interrupt(struct phy_device *phydev);
+ int phy_config_interrupt(struct phy_device *phydev, u32 interrupts);
+
+ Clear the PHY's interrupt, and configure which ones are allowed,
+ respectively. Currently only supports all on, or all off.
+
+ int phy_enable_interrupts(struct phy_device *phydev);
+ int phy_disable_interrupts(struct phy_device *phydev);
+
+ Functions which enable/disable PHY interrupts, clearing them
+ before and after, respectively.
+
+ int phy_start_interrupts(struct phy_device *phydev);
+ int phy_stop_interrupts(struct phy_device *phydev);
+
+ Requests the IRQ for the PHY interrupts, then enables them for
+ start, or disables then frees them for stop.
+
+ struct phy_device * phy_attach(struct net_device *dev, const char *phy_id,
+ u32 flags);
+
+ Attaches a network device to a particular PHY, binding the PHY to a generic
+ driver if none was found during bus initialization. Passes in
+ any phy-specific flags as needed.
+
+ int phy_start_aneg(struct phy_device *phydev);
+
+ Using variables inside the phydev structure, either configures advertising
+ and resets autonegotiation, or disables autonegotiation, and configures
+ forced settings.
+
+ static inline int phy_read_status(struct phy_device *phydev);
+
+ Fills the phydev structure with up-to-date information about the current
+ settings in the PHY.
+
+ void phy_sanitize_settings(struct phy_device *phydev)
+
+ Resolves differences between currently desired settings, and
+ supported settings for the given PHY device. Does not make
+ the changes in the hardware, though.
+
+ int phy_ethtool_sset(struct phy_device *phydev, struct ethtool_cmd *cmd);
+ int phy_ethtool_gset(struct phy_device *phydev, struct ethtool_cmd *cmd);
+
+ Ethtool convenience functions.
+
+ int phy_mii_ioctl(struct phy_device *phydev,
+ struct mii_ioctl_data *mii_data, int cmd);
+
+ The MII ioctl. Note that this function will completely screw up the state
+ machine if you write registers like BMCR, BMSR, ADVERTISE, etc. Best to
+ use this only to write registers which are not standard, and don't set off
+ a renegotiation.
+
+
+PHY Device Drivers
+
+ With the PHY Abstraction Layer, adding support for new PHYs is
+ quite easy. In some cases, no work is required at all! However,
+ many PHYs require a little hand-holding to get up-and-running.
+
+Generic PHY driver
+
+ If the desired PHY doesn't have any errata, quirks, or special
+ features you want to support, then it may be best to not add
+ support, and let the PHY Abstraction Layer's Generic PHY Driver
+ do all of the work.
+
+Writing a PHY driver
+
+ If you do need to write a PHY driver, the first thing to do is
+ make sure it can be matched with an appropriate PHY device.
+ This is done during bus initialization by reading the device's
+ UID (stored in registers 2 and 3), then comparing it to each
+ driver's phy_id field by ANDing it with each driver's
+ phy_id_mask field. Also, it needs a name. Here's an example:
+
+ static struct phy_driver dm9161_driver = {
+ .phy_id = 0x0181b880,
+ .name = "Davicom DM9161E",
+ .phy_id_mask = 0x0ffffff0,
+ ...
+ }
+
+ Next, you need to specify what features (speed, duplex, autoneg,
+ etc) your PHY device and driver support. Most PHYs support
+ PHY_BASIC_FEATURES, but you can look in include/mii.h for other
+ features.
+
+ Each driver consists of a number of function pointers:
+
+ config_init: configures PHY into a sane state after a reset.
+ For instance, a Davicom PHY requires descrambling disabled.
+ probe: Does any setup needed by the driver
+ suspend/resume: power management
+ config_aneg: Changes the speed/duplex/negotiation settings
+ read_status: Reads the current speed/duplex/negotiation settings
+ ack_interrupt: Clear a pending interrupt
+ config_intr: Enable or disable interrupts
+ remove: Does any driver take-down
+
+ Of these, only config_aneg and read_status are required to be
+ assigned by the driver code. The rest are optional. Also, it is
+ preferred to use the generic phy driver's versions of these two
+ functions if at all possible: genphy_read_status and
+ genphy_config_aneg. If this is not possible, it is likely that
+ you only need to perform some actions before and after invoking
+ these functions, and so your functions will wrap the generic
+ ones.
+
+ Feel free to look at the Marvell, Cicada, and Davicom drivers in
+ drivers/net/phy/ for examples (the lxt and qsemi drivers have
+ not been tested as of this writing)

+ * - If autonegotiation finishes, but there's no link, it sets

+ * of time, autonegotiation should be tried again if the PHY
+ * supports "magic" autonegotiation (back to AN)
+ * - If it didn't finish, and no magic_aneg, move to FORCING.

+ * - If the timer notes that the link comes back, we move to RUNNING
+ * - config_aneg moves to AN
+ * - phy_stop moves to HALTED
+ *
+ * FORCING: PHY is being configured with forced settings
+ * - if link is up, move to RUNNING
+ * - If link is down, we drop to the next highest setting, and
+ * retry (FORCING) after a timeout
+ * - phy_stop moves to HALTED
+ *
+ * RUNNING: PHY is currently up, running, and possibly sending
+ * and/or receiving packets
+ * - timer will set CHANGELINK if we're polling (this ensures the
+ * link state is polled every other cycle of this state machine,
+ * which makes it every other second)

From ebed67d2847a9d299b47eeb5d82744671ab2b198 Mon Sep 17 00:00:00 2001
From: Jouni Malinen <jkmaline@cc.hut.fi>
Date: Sat, 30 Jul 2005 20:43:19 -0700
Subject: [PATCH 077/997] [PATCH] hostap: Start using net/ieee80211.h
Preparations for starting to use net/ieee80211 instead of private
IEEE 802.11 implementation. Include net/ieee80211.h and
net/ieee80211_crypt.h into files that will be needed these in the
future. Remove duplicate definitions from hostap_common.h and
rename WLAN_FC_GET_{TYPE,STYPE} macros for now sinc net/ieee80211.h
is using incompatible definitions. This will be resolved in the
future by updating Host AP to use the versions that do not shift
type/stype.

Date: Sat, 30 Jul 2005 20:43:20 -0700
Subject: [PATCH 078/997] [PATCH] hostap: Replace crypto code with
net/ieee80211 version
Replace Host AP version of WEP, TKIP, CCMP implementation with
net/ieee80211 that has more or less identical implementation (since
it is based on the Host AP implementation). Remove Host AP specific
implementation and modules from drivers/net/wireless/hostap.

Subject: [PATCH 080/997] [PATCH] tms380tr: move to DMA API
This patch makes tms380tr use the new DMA API. Now that on Alpha, this API
also supports bus master DMA for ISA (platform) devices, i changed the
driver to use this new API.
This also works around a bug in the firmware loader: The example provided
in Documentation/firmware_class no longer works, as the firmware loader now
calls get_kobj_path_length() and the kernel promptly oopses, as the
home-grown device doesn't have a parent. Of course, this doesn't happen
with a "real" device which has its bus (or pseudo bus in the case of
platform) as parent.
Converted tms380tr to use new DMA API:
- proteon.c, skisa.c: use platform pseudo bus to create a struct device
- Space.c: delete init hooks
- abyss.c, tmspci.c: pass struct device to tms380tr.c
- tms380tr.c, tms380tr.h: new DMA API, use real device fo firmware loader

Subject: [PATCH 102/997] drm: updated DRM map patch for 32/64 bit systems
I basically combined Paul's patches with additions that I had made
for PCI scatter gather.
I also tried more carefully to avoid problems with the same token
assigned multiple times while trying to use the base address in the
token if possible to gain as much backward compatibility as possible
for broken DRI clients.

Subject: [PATCH 103/997] drm: switch drm_handle_t to unsigned int
This converts the drm_handle_t to unsigned int.
This is currently safe to do as we don't pass these across the kernel/user
boundary, but userspace does use these, but no-one builds userspace against
the kernel headers at present so it is okay to switch over the kernel copy
of drm.h at this point. (The CVS tree will switch over soon in sync with
some Mesa changes)

Subject: [PATCH 106/997] [IPSEC]: Restrict socket policy loading to
CAP_NET_ADMIN.
The interface needs much redesigning if we wish to allow
normal users to do this in some way.

Subject: [PATCH 107/997] [TG3]: Save initial PCI state before registering the
netdevice.
Else on SMP systems it is possible for hotplug to execute,
invoke tg3_open(), and end up loading the uninitialized
PCI register save area into the card.

+ * 2.2 Implemented SAVAGE_CMD_DMA_IDX and SAVAGE_CMD_VB_IDX
+ * 2.3 Event counters used by BCI_EVENT_EMIT/WAIT ioctls are now 32 bits
+ * wide and thus very long lived (unlikely to ever wrap). The size

Subject: [PATCH 112/997] [SCSI] Bug 4940 Repeatable Kernel Panic on Adaptec
2015S I20 device on bootup
From: "Salyzyn, Mark" <mark_salyzyn@adaptec.com>
Prevent driver from loading if another driver (i2o) has already claimed
the resources associated with the card. Discussion associated with this
bug can be referenced at http://bugzilla.kernel.org/show_bug.cgi?id=4940
where it was agreed to use pci_request_regions in both the dpt_i2o and
the i2o driver to prevent both drivers loading on the same adapter(s).

Subject: [PATCH 113/997] [PATCH] ppc64: add default config for BPA
This adds a bpa_defconfig file and make target. The config settings
are made for the current version of the Cell Processor Based Blade,
so there are not too many drivers enabled. A few more drivers might
get added in the future though.

From db6778db7eb1d974e1ae0da326530f09c13585ac Mon Sep 17 00:00:00 2001
From: Antonino Daplas <adaplas@pol.net>

Subject: [PATCH 115/997] [PATCH] nvidiafb: Fix initial display corruption on
certain laptops
Reported by:Vincent Fortier (Bugzilla Bug 4768)
"At boot time the screen appears moved to the mid right portion of the actual
video pannel making the end of the line appears at the left edge... It simply
looks like moved half way to the right"
His particular hardware has a display with an unusual dimension (1920x1200) but
unfortunately has no EDID block. None of the entries in the global mode
database is correct for this particular display, and it particularly has
difficulty scaling up 640x480 (the default startup mode of nvidiafb) to
1920x1200 which causes the above described problem.
1, Add 1920x1200 to the global mode database.
2. Let nvidiafb base the startup mode from the flatpanel dimensions only if the
EDID block is absent, no boot mode parameter is specified by the user, and
a flatpanel/LCD display is attached.

Subject: [PATCH 116/997] [PATCH] VIA VT8235 PCI quirk
Like many other southbridges from different manufacturers, VIA VT8235
chip has two non-standard BARs for power management and SMBus registers
(see the datasheet at http://www.via.com.tw).
This new quirk routine fixes boot problem with 2.6.13-rc2/rc6 kernels on
Targa Visionary 811 Athlon64 laptop, as reported by Mikael Pettersson
<mikpe@csd.uu.se>.

Subject: [PATCH 118/997] [PATCH] don't try to do any NAT on untracked
connections
With the introduction of 'rustynat' in 2.6.11, the old tricks of preventing
NAT of 'untracked' connections (e.g. NOTRACK target in 'raw' table) are no
longer sufficient.
The ip_conntrack_untracked.status |= IPS_NAT_DONE_MASK effectively
prevents iteration of the 'nat' table, but doesn't prevent nat_packet()
to be executed. Since nr_manips is gone in 'rustynat', nat_packet() now
implicitly thinks that it has to do NAT on the packet.
This patch fixes that problem by explicitly checking for
ip_conntrack_untracked in ip_nat_fn().

Subject: [PATCH 121/997] [PATCH] fsnotify_name/inoderemove
The patch below unhooks fsnotify from vfs_unlink & vfs_rmdir. It
introduces two new fsnotify calls, that are hooked in at the dcache
level. This not only more closely matches how the VFS layer works, it
also avoids the problem with locking and inode lifetimes.
The two functions are
- fsnotify_nameremove -- called when a directory entry is going away.
It notifies the PARENT of the deletion. This is called from
d_delete().
- inoderemove -- called when the files inode itself is going away. It
notifies the inode that is being deleted. This is called from
dentry_iput().

Subject: [PATCH 124/997] [SCSI] fix target scanning oops with fc transport
class
We have some nasty issues with 2.6.12-rc6. Any request to scan on
the lpfc or qla2xxx FC adapters will oops. What is happening is the
system is defaulting to non-transport registered targets, which
inherit the parent of the scan. On this second scan, performed by
the attribute, the parent becomes the shost instead of the rport.
The slave functions in the 2 FC adapters use starget_to_rport()
routines, which incorrectly map the shost as an rport pointer.
Additionally, this pointed out other weaknesses:
- If the target structure is torn down outside of the transport,
we have no method for it to be regenerated at the proper parent.
- We have race conditions on the target being allocated by both
the midlayer scan (parent=shost) and by the fc transport
(parent=rport).

Subject: [PATCH 134/997] [PATCH] cpuset release ABBA deadlock fix
Fix possible cpuset_sem ABBA deadlock if 'notify_on_release' set.
For a particular usage pattern, creating and destroying cpusets fairly
frequently using notify_on_release, on a very large system, this deadlock
can be seen every few days. If you are not using the cpuset
notify_on_release feature, you will never see this deadlock.
The existing code, on task exit (or cpuset deletion) did:
get cpuset_sem
if cpuset marked notify_on_release and is ready to release:
compute cpuset path relative to /dev/cpuset mount point
call_usermodehelper() forks /sbin/cpuset_release_agent with path
drop cpuset_sem
Unfortunately, the fork in call_usermodehelper can allocate memory, and
allocating memory can require cpuset_sem, if the mems_generation values
changed in the interim. This results in an ABBA deadlock, trying to obtain
cpuset_sem when it is already held by the current task.
To fix this, I put the cpuset path (which must be computed while holding
cpuset_sem) in a temporary buffer, to be used in the call_usermodehelper
call of /sbin/cpuset_release_agent only _after_ dropping cpuset_sem.
So the new logic is:
get cpuset_sem
if cpuset marked notify_on_release and is ready to release:
compute cpuset path relative to /dev/cpuset mount point
stash path in kmalloc'd buffer
drop cpuset_sem
call_usermodehelper() forks /sbin/cpuset_release_agent with path
free path
The sharp eyed reader might notice that this patch does not contain any
calls to kmalloc. The existing code in the check_for_release() routine was
already kmalloc'ing a buffer to hold the cpuset path. In the old code, it
just held the buffer for a few lines, over the cpuset_release_agent() call
that in turn invoked call_usermodehelper(). In the new code, with the
application of this patch, it returns that buffer via the new char
**ppathbuf parameter, for later use and freeing in cpuset_release_agent(),
which is called after cpuset_sem is dropped. Whereas the old code has just
one call to cpuset_release_agent(), right in the check_for_release()
routine, the new code has three calls to cpuset_release_agent(), from the
various places that a cpuset can be released.
This patch has been build and booted on SN2, and passed a stress test that
previously hit the deadlock within a few seconds.

Subject: [PATCH 137/997] [PATCH] i2o: remove new configuration API
Remove new configuration API from i2o_config
The API-patch is still available from the I2O website (which is mentioned in
the kernel config now). It is removed because it creates a new binary
sysfs-attribute, which doesn't have the limitiation of 4k. Expect for the
Adaptec controllers, which has a limitation in the hardware this attribute
doesn't make sense anywhere else. Until the sysfs API provides an attribute
which doesn't buffer (like firmware) and let access to at least 64k blocks i
provide a separate patch...
(akpm: basically, this API was introduced post-2.6.12 and Markus wants to pull
it out before 2.6.13).

Subject: [PATCH 138/997] [SPARC]: Use kthread infrastructure in envctrl
envctrl currently uses very odd ways to stop a thread, using various
things that should be exposed to drivers at all.
This patch (which is untested as I don't have sparc hardware) switches
it to use the proper kthread infrastructure.

Subject: [PATCH 143/997] [NET]: Fix memory leak in sys_{send,recv}msg()
w/compat
From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com>
sendmsg()/recvmsg() syscalls from o32/n32 apps to a 64bit kernel will
cause a kernel memory leak if iov_len > UIO_FASTIOV for each syscall!
This is because both sys_sendmsg() and verify_compat_iovec() kmalloc a
new iovec structure. Only the one from sys_sendmsg() is free'ed.
I wrote a simple test program to confirm this after identifying the
problem:
http://davej.org/programs/testsendmsg.c
Note that the below fix will break solaris_sendmsg()/solaris_recvmsg() as
it also calls verify_compat_iovec() but expects it to malloc internally.
[ I fixed that. -DaveM ]

Added pci_request_regions() before using the controller to avoid duplicate
usage of the I2O controller when the dpt_i2o driver and I2O subsystem is
loaded at the same time.

Subject: [PATCH 151/997] [ARM] Control v6 'global' bit via Linux PTE entries
Unfortunately, we can't use the "user" bit in the page tables to
control whether a page table entry is "global" or "asid" specific,
since the vector page is mapped as "user" accessible but is not
process specific.
Therefore, give direct control of the ARMv6 "nG" (not global)
bit to the mm layers.

+ S3C24XX USB Host support
+ ========================
+
+
+
+Introduction
+------------
+
+ This document details the S3C2410/S3C2440 in-built OHCI USB host support.
+
+Configuration
+-------------
+
+ Enable at least the following kernel options:
+
+ menuconfig:
+
+ Device Drivers --->
+ USB support --->
+ <*> Support for Host-side USB
+ <*> OHCI HCD support
+
+
+ .config:
+ CONFIG_USB
+ CONFIG_USB_OHCI_HCD
+
+
+ Once these options are configured, the standard set of USB device
+ drivers can be configured and used.
+
+
+Board Support
+-------------
+
+ The driver attaches to a platform device, which will need to be
+ added by the board specific support file in linux/arch/arm/mach-s3c2410,
+ such as mach-bast.c or mach-smdk2410.c
+
+ The platform device's platform_data field is only needed if the
+ board implements extra power control or over-current monitoring.
+
+ The OHCI driver does not ensure the state of the S3C2410's MISCCTRL
+ register, so if both ports are to be used for the host, then it is
+ the board support file's responsibility to ensure that the second
+ port is configured to be connected to the OHCI core.
+
+
+Platform Data
+-------------
+
+ See linux/include/asm-arm/arch-s3c2410/usb-control.h for the
+ descriptions of the platform device data. An implementation
+ can be found in linux/arch/arm/mach-s3c2410/usb-simtec.c .
+
+ The `struct s3c2410_hcd_info` contains a pair of functions
+ that get called to enable over-current detection, and to
+ control the port power status.
+
+ The ports are numbered 0 and 1.
+
+ power_control:
+
+ Called to enable or disable the power on the port.
+
+ enable_oc:
+
+ Called to enable or disable the over-current monitoring.
+ This should claim or release the resources being used to
+ check the power condition on the port, such as an IRQ.
+
+ report_oc:
+
+ The OHCI driver fills this field in for the over-current code
+ to call when there is a change to the over-current state on
+ an port. The ports argument is a bitmask of 1 bit per port,
+ with bit X being 1 for an over-current on port X.
+
+ The function s3c2410_usb_report_oc() has been provided to
+ ensure this is called correctly.
+
+ port[x]:
+
+ This is struct describes each port, 0 or 1. The platform driver
+ should set the flags field of each port to S3C_HCDFLG_USED if
+ the port is enabled.
+
+

Patch from Ben Dooks
Rename the s3c2410_report_oc() to s3c2410_usb_report_oc()
as this is an usb specific function.
Change port power on the usb-simtec implementation to only
power up the output if both are set, as per the usb 1.1
specification

sata_sx4 directly references sg->length to calculate total_len in
pdc20621_dma_prep(). This is incorrect as dma_map_sg() could have
merged multiple sg's into one and, in such case, sg->length doesn't
reflect true size of the entry. This patch makes it use
sg_dma_len(sg).

Subject: [PATCH 166/997] [IA64] Spinlock optimizations
1. Nontemporal store for spin unlock.
A nontemporal store will not update the LRU setting for the cacheline. The
cacheline with the lock may therefore be evicted faster from the cpu
caches. Doing so may be useful since it increases the chance that the
exclusive cache line has been evicted when another cpu is trying to
acquire the lock.
The time between dropping and reacquiring a lock on the same cpu is
typically very small so the danger of the cacheline being
evicted is negligible.
2. Avoid semaphore operation in write_unlock and use nontemporal store
write_lock uses a cmpxchg like the regular spin_lock but write_unlock uses
clear_bit which requires a load and then a loop over a cmpxchg. The
following patch makes write_unlock simply use a nontemporal store to clear
the highest 8 bits. We will then still have the lower 3 bytes (24 bits)
left to count the readers.
Doing the byte store will reduce the number of possible readers from 2^31
to 2^24 = 16 million.
These patches were discussed already:
http://marc.theaimsgroup.com/?t=111472054400001&r=1&w=2
http://marc.theaimsgroup.com/?l=linux-ia64&m=111401837707849&w=2
The nontemporal stores will only work using GCC. If a compiler is used
that does not support inline asm then fallback C code is used. This
will preserve the byte store but not be able to do the nontemporal stores.

when the commands succeeds in reserving the session but fails
when it actually tries to attach to the load_pid. In that case,
the command has failed but will return 0. More importantly,
the session will remain reserved. This patch fixes the problem.

Subject: [PATCH 168/997] [TCP]: Adjust {p,f}ackets_out correctly in
tcp_retransmit_skb()
Well I've only found one potential cause for the assertion
failure in tcp_mark_head_lost. First of all, this can only
occur if cnt > 1 since tp->packets_out is never zero here.
If it did hit zero we'd have much bigger problems.
So cnt is equal to fackets_out - reordering. Normally
fackets_out is less than packets_out. The only reason
I've found that might cause fackets_out to exceed packets_out
is if tcp_fragment is called from tcp_retransmit_skb with a
TSO skb and the current MSS is greater than the MSS stored
in the TSO skb. This might occur as the result of an expiring
dst entry.
In that case, packets_out may decrease (line 1380-1381 in
tcp_output.c). However, fackets_out is unchanged which means
that it may in fact exceed packets_out.
Previously tcp_retrans_try_collapse was the only place where
packets_out can go down and it takes care of this by decrementing
fackets_out.
So we should make sure that fackets_out is reduced by an appropriate
amount here as well.

Subject: [PATCH 169/997] [PATCH] S2io: Code cleanup
Hi,
We are submitting a series of 13 patches to support our Xframe I and
Xframe II line of products. The patches can be categorized as follows:
Patches 1-8 : Changes applicable to both Xframe I and II
Patches 9-11: Xframe II specific features
Patch 12: Addresses issues found during testing cycle.
Patch 13: Incorpoates mostly the review comments from community
and some last moment bug fixes.
Please review the patches and let us know your comments.
Starting with patch 1 below.
This patch involves cosmetic changes(tabs and indentation,
regrouping of transmit and receive data structures, typecasting,
code cleanup).

Subject: [PATCH 170/997] [PATCH] S2io: Hardware fixes
Hi,
Below patch addresses few h/w specific issues.
1. Check for additional ownership bit on Rx path before
starting Rx processing.
2. Enable only 4 PCCs(Per Context Controller) for Xframe I
revisions less than 4.
3. Program Rx and Tx round robin registers depending on
no. of rings/FIFOs.
4. Tx continous interrupts is now a loadable parameter.
5. Reset the card if we get double-bit ECC errors.
6. A soft reset of XGXS being done to force a link state change has been
eliminated.
7. After a reset, clear "parity error detected" bit,
PCI-X ECC status register, and PCI_STATUS bit in
tx_pic_int register.
8. The error in the disabling allmulticast implementation has been
rectified.
9. Leave the PCI-X parameters MMRBC, OST etc. at their
BIOS/system defaults.

Subject: [PATCH 171/997] [PATCH] S2io: Software fixes
Hi,
Below patch includes fixes for few purely software bugs identified
since last release.
1. Keep track and display(as part of ethtool command output) the no.
of single-bit and double-bit ECC errors.
2. Handle race condition between intr handler and "interface down"
routine.
3. Initial link state setting modified so that the link state displayed
after "interface Up" is correct.
4. Fix for "Incorrect Tx packet count when TSO is enabled".
5. Disable periodic DMA of statistics and schedule one-shot DMA
only when required.

Subject: [PATCH 173/997] [PATCH] S2io: Performance improvements
Hi,
This patch relates to mostly performance related changes.
1. Fixed incorrect computation of PANIC level in rx_buffer_level().
2. Removed unnecessary PIOs(read/write of tx_traffic_int and
rx_traffic_int) from interrupt handler and removed read of
general_int_status register from xmit routine.
3. Enable two-buffer mode(for Rx path) automatically for SGI
systems. This improves Rx performance dramatically on
SGI systems.

Subject: [PATCH 175/997] [PATCH] S2io: Timer based slowpath handling
Hi,
This patch implements the slow-path handling functions(link
state change, hardware errors) as a timer. It is not
handled in interrupt handler as was done previously.

Includes the following changes:
1. New values to program XAUI interface.
2. Print the PCI/PCI-X mode(bus frequency, width).
3. Remove EOI from reset during intialization.
4. Enable all 8 PCCs if Xframe II adapter.
5. Programs the RLDRAM size depending on the device.
(Note: RLDRAM size on XFARME-I is 64Mb whereas on XFRAME-II it's 32 Mb).
6. Enable extended(64-bit) statistics counters.
7. Program timer interrupt duration based on PCI/PCI-X clock speed.
8. Not required to save/restore PCI config space before/after reset.

Subject: [PATCH 178/997] [PATCH] S2io: Support for bimodal interrupts
Hi,
This is a patch to provide bimodal interrupt moderation support for
Xframe II adapter. Basically, in this moderation scheme, the adapter
raises a traffic interrupt if the no. of packets transmitted and/or
received reaches a programmable threshold.

Subject: [PATCH 180/997] [PATCH] S2io: Miscellaneous fixes
Hi,
The last patch in this series fixes the following issues found during
testing.
1. Ensure we don't pass zero sized buffers to the card(which can lockup)
2. Restore the PCI-X parameters(in case of Xframe I adapter) after a reset.
3. Make sure total size of all FIFOs does not exceed 8192.

Subject: [PATCH 181/997] [PATCH] S2io: Errors found during review
Hi,
This is a patch to incorporate comments from earlier 12 patches.
It also fixes a few issues we found during this time.
Following is a list of changes in this patch. Item 1 incorporates
earlier comments. Issues addressed in items 2 to 4 were discovered
recently.
1. wmb() call in s2io_xmit() replaced with mmiowb().
2. The dtx_control register was earlier programmed incorrectly
for Xframe II adapter.
3. As suggested by hardware team, after a reset, in case of
Xframe II adapter, we clear certain spurious errors by
clearing PCI-X ECC status register, "detected parity error"
bit in PCI_STATUS register and PCI_STATUS bit in txpic_int register.
4. On IBM PPC platforms, we found that in the Rx buffer replenish
function, two memory writes(one to the the descriptor length and
another to the ownership) were getting reordered. This was causing
the adapter to see the ownership transfered to it before the length
was updated.
One solution was to add a wmb() but since this would turnout expensive
on some platforms if called for every descriptor, we set the ownership
bit and other fields of '2' to 'N' Rx descriptors followed by a wmb()
and then set the ownership of first descriptor ('1').
Here the value 'N' is configurable by making it a module loadable
parameter (rxsync_frequency).
(NOTE: This parameter is a power of 2).
5. Bumped up the driver version no. to 2.0.2.1

Subject: [PATCH 202/997] [NET]: Make skb->protocol __be16
There are many instances of
skb->protocol = htons(ETH_P_*);
skb->protocol = __constant_htons(ETH_P_*);
and
skb->protocol = *_type_trans(...);
Most of *_type_trans() are already endian-annotated, so, let's shift
attention on other warnings.

Initialize npinfo->rx_flags. The way it stands now, this will have random
garbage, and so will incur a locking penalty even when an rx_hook isn't

This fixes an obvious deadlock in the netpoll code. netpoll_rx takes the
npinfo->rx_lock. netpoll_rx is also the only caller of arp_reply (through
__netpoll_rx). As such, it is not necessary to take this lock.

Subject: [PATCH 207/997] [NETPOLL]: add retry timeout
Add limited retry logic to netpoll_send_skb
Each time we attempt to send, decrement our per-device retry counter.
On every successful send, we reset the counter.
We delay 50us between attempts with up to 20000 retries for a total of
1 second. After we've exhausted our retries, subsequent failed
attempts will try only once until reset by success.

Subject: [PATCH 208/997] [NETPOLL]: pre-fill skb pool
we could do one thing (see the patch below): i think it would be useful
to fill up the netlogging skb queue straight at initialization time.
Especially if netpoll is used for dumping alone, the system might not be
in a situation to fill up the queue at the point of crash, so better be
a bit more prepared and keep the pipeline filled.
[ I've modified this to be called earlier - mpm ]

Changes:
- Modify ata_mmio_data_xfer() and ata_pio_data_xfer() to handle odd-lengthed buffer.
- Add some function comments
This patch does not reuse ap->pad as alignment buffer since
using local variable seems good enough.

Subject: [PATCH 215/997] [IA64] Fix race in mm-context wrap-around logic.
The patch below should fix a race which could cause stale TLB entries.
Specifically, when 2 CPUs ended up racing for entrance to
wrap_mmu_context(). The losing CPU would find that by the time it
acquired ctx.lock, mm->context already had a valid value, but then it
failed to (re-)check the delayed TLB flushing logic and hence could
end up using a context number when there were still stale entries in
its TLB. The fix is to check for delayed TLB flushes only after
mm->context is valid (non-zero). The patch also makes GCC v4.x
happier by defining a non-volatile variant of mm_context_t called
nv_mm_context_t.

Subject: [PATCH 216/997] Fix up mmap of /dev/kmem
This leaves the issue of whether we should deprecate the whole thing (or
if we should check the whole mmap range, for that matter) open. Just do
the minimal fix for now.

There was a rather silly and embarrassing typo in the sh _syscall6().
For the syscall ABI we have the trapa value specified as 0x10 + number
of arguments, this was being set incorrectly in the _syscall6() case
which ended up causing some problems for users.

Subject: [PATCH 223/997] [PATCH] hostap: Fix skb->cb use for TX meta data
Old AP mode code for power saving was using skb->cb for couple of
flags before the more generic 802.11 TX code started using the same
buffer for struct hostap_skb_tx_data. This resulted in the power save
code corrupting the magic value in beginning of the buffer and TX code
dropping the power saved packets because of this for the case where
STAs send PS-Poll frames with PwrMgmt flag set.
This patch modifies the power save code to use the same struct
hostap_skb_tx_data as rest of the TX path in order to avoid corrupting
the data in skb->cb.
In addition, this patch reorders fields in the structure and makes
them use smaller types in order to make the structure fit in skb->cb
on 64-bit hosts.

Subject: [PATCH 224/997] [PATCH] hostap: Remove experimental PCI bus
master/DMA code
PCI version of Prism2.5/3 has undocumented DMA support for TX/RX data,
but this seems to have some hardware bugs that prevent it from being
used properly for TX. RX side could possibly be made to work reliably.
Even though DMA support would be very useful for saving host CPU (from
about 40% to 5-10% when operating at maximum throughput), it seems to
be best to just remove this code finally. The implementation has
always been commented out by default and has received very limited
testing. The code may have already been broken number of times and I
don't have much interested in trying to verify whether it works or
not. Getting this out makes it easier to maintain the driver and
allows some cleanups that have been partly postponed because of this
experimental bus master/DMA code.

Subject: [PATCH 225/997] [PATCH] hostap: Use void *hw_priv instead of #ifdef
in local data
Replace hardware model specific #ifdef's in struct local_info with
void *hw_priv that is pointing to cs/pci/plx specific data
structure. This removes unneeded #ifdef's and as such, is a step
towards making it possible to share objects for hostap_hw.c and
hostap_download.c with cs/pci/plx drivers without having to compile
and link the same code separately for each one.

Subject: [PATCH 229/997] [PATCH] ieee80211: Fix frame control pver mask
IEEE 802.11 frame control has two bits reserved for protocol
version. IEEE80211_FCTL_VERS was not used anywhere, but I would assume
it was supposed to be a mask for the protocol field and as such, it
should be 0x0003, not 0x0002. This matches with WLAN_FC_PVER
definition in hostap.

Subject: [PATCH 230/997] [PATCH] ieee80211: Capability field is called ESS,
not BSS
IEEE 802.11 has a capability field flag called ESS, but ieee80211 had
renamed this to BSS for some reason. hostap has been using
WLAN_CAPABILITY_ESS and since that matches with the standard, lets use
it as the name for this define. Add WLAN_CAPABILITY_BSS as a backwards
compatibility name for the same bit since ieee80211 and ipw2200 are
using this and there are versions outside kernel tree that expect to
find this define name.

Subject: [PATCH 232/997] [PATCH] hostap: Replace WLAN_FC_ defines with
ieee80211 ones
Replace remaining WLAN_FC_* defines with the ones used in ieee80211
header file. This completes the move from hostap version of frame
control field processing to ieee80211 version.

watch /etc/mtab
- app2:
cp /etc/mtab /tmp/mtab-work
mv /etc/mtab /etc/mtab~
mv /tmp/mtab-work /etc/mtab
app1 still thinks it's watching /etc/mtab but it's actually watching

Subject: [PATCH 239/997] [PATCH] intelfb/fbdev: Save info->flags in a local
variable
Reported by: Pavel Kysilka (Bugzilla Bug 5059)
The intelfb driver does not keep resolution set with fbset after
switching to anot console and back.
Steps to reproduce:
initial options: tty1,tty2 - 1024x768-60
1) tty1 - fbset after booting (1024x768-60)
2) tty1 - fbset 800x600-100
tty1: 800x600-100
3) swith to tty2, swith to tty1
tty1: 1024x768-60 (the same resolution as default from kernel booting)
This bug is caused by intelfb unintentionally destroying info->flags in
set_par(). Therefore the flag, FBINFO_MISC_USEREVENT used to notify
fbcon of a mode change was cleared causing the above problem. This bug
though is not intelfb specific, as other drivers may also be affected.
The fix is to save info->flags in a local variable before calling any
of the driver hooks. A more definitive fix (for post 2.6.13) is to
separate info->flags into one that is set by the driver and another that
is set by core fbdev/fbcon.

exception handling
Patch from Richard Purdie
The exception handling code fails to compile if the extended
precision mode is enabled. This patch fixes those compile errors and
also stops _quiet functions from incorrectly raising exceptions.

Subject: [PATCH 242/997] [IA64-SGI] fix unaligned memory access in
snsc_event.c
It's been pointed out that environmental events from the system
controllers on Altix machines cause the kernel to complain about
unaligned memory accesses. This turns out to be because
"be32_to_cpup()" didn't do everything I thought/hoped it did.
I've added calls to pull the offending integers out of the
buffers using get_unaligned() before feeding them to
be32_to_cpup().

+// The ALU instructions register blocks are enumerated according to the order
+// in which fglrx. I assume there is space for 64 instructions, since
+// each block has space for a maximum of 64 DWORDs, and this matches reported
+// native limits.
+//
+// The basic functional block seems to be one MAD for each color and alpha,
+// and an adder that adds all components after the MUL.
+// - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands
+// - DP4: Use OUTC_DP4, OUTA_DP4
+// - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
+// - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
+// - CMP: If ARG2 < 0, return ARG1, else return ARG0
+// - FLR: use FRC+MAD
+// - XPD: use MAD+MAD
+// - SGE, SLT: use MAD+CMP
+// - RSQ: use ABS modifier for argument
+// - Use OUTC_REPL_ALPHA to write results of an alpha-only operation (e.g. RCP)
+// into color register
+// - apparently, there's no quick DST operation
+// - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
+// - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
+// - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
+//
+// Operand selection
+// First stage selects three sources from the available registers and
+// constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
+// fglrx sorts the three source fields: Registers before constants,
+// lower indices before higher indices; I do not know whether this is necessary.
+// fglrx fills unused sources with "read constant 0"
+// According to specs, you cannot select more than two different constants.
+//
+// Second stage selects the operands from the sources. This is defined in
+// INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
+// zero and one.
+// Swizzling and negation happens in this stage, as well.
+//
+// Important: Color and alpha seem to be mostly separate, i.e. their sources
+// selection appears to be fully independent (the register storage is probably
+// physically split into a color and an alpha section).
+// However (because of the apparent physical split), there is some interaction
+// WRT swizzling. If, for example, you want to load an R component into an
+// Alpha operand, this R component is taken from a *color* source, not from
+// an alpha source. The corresponding register doesn't even have to appear in
+// the alpha sources list. (I hope this alll makes sense to you)
+//
+// Destination selection
+// The destination register index is in FPI1 (color) and FPI3 (alpha) together
+// with enable bits.
+// There are separate enable bits for writing into temporary registers
+// (DSTC_REG_* /DSTA_REG) and and program output registers (DSTC_OUTPUT_* /DSTA_OUTPUT).
+// You can write to both at once, or not write at all (the same index
+// must be used for both).
+//
+// Note: There is a special form for LRP
+// - Argument order is the same as in ARB_fragment_program.
+// - Operation is MAD
+// - ARG1 is set to ARGC_SRC1C_LRP/ARGC_SRC1A_LRP
+// - Set FPI0/FPI2_SPECIAL_LRP
+// Arbitrary LRP (including support for swizzling) requires vanilla MAD+MAD */

Subject: [PATCH 250/997] [PATCH] NFS: Ensure we always update inode->i_mode
when doing O_EXCL creates
When the client performs an exclusive create and opens the file for writing,
a Netapp filer will first create the file using the mode 01777. It does this
since an NFSv3/v4 exclusive create cannot immediately set the mode bits.
The 01777 mode then gets put into the inode->i_mode. After the file creation
is successful, we then do a setattr to change the mode to the correct value
(as per the NFS spec).
The problem is that nfs_refresh_inode() no longer updates inode->i_mode, so
the latter retains the 01777 mode. A bit later, the VFS notices this, and calls
remove_suid(). This of course now resets the file mode to inode->i_mode & 0777.
Hey presto, the file mode on the server is now magically changed to 0777. Duh...

Subject: [PATCH 252/997] [PATCH] i386 / desc_empty macro is incorrect
Chuck Ebbert noticed that the desc_empty macro is incorrect. Fix it.
Thankfully, this is not used as a security check, but it can falsely
overwrite TLS segments with carefully chosen base / limits. I do not
believe this is an issue in practice, but it is a kernel bug.

Subject: [PATCH 253/997] [PATCH] skge: stop bogus sensor messages
Some versions of the Marvell yukon generate bogus sensor warning interrupts.
The driver would flood log with these messages. Handle this situation
cleanly by masking away at boot time.

cleanups
The main issue is that bus_fixup calls may potentially call
functions that require a valid bus->sysdata pointer. Since
this is the case, we must set the bus->sysdata pointer before
calling the bus_fixup functions. The remaining changes are
simple fixes to make sure memory is cleaned up in the function.

Subject: [PATCH 260/997] [IA64] Updated zx1 defconfig
Just `make oldconfig' doesn't help for the zx1 defconfig ---
because we need the MPT Fusion drivers, which are picked up as not
selected.
Tested on HP ZX2000 and ZX2600.

Subject: [PATCH 261/997] [IPV6]: Fix raw socket hardware checksum failures
When packets hit raw sockets the csum update isn't done yet, do it manually.
Packets can also reach rawv6_rcv on the output path through
ip6_call_ra_chain, in this case skb->ip_summed is CHECKSUM_NONE and this
codepath isn't executed.

Subject: [PATCH 262/997] [TCP]: Fix bug #5070: kernel BUG at
net/ipv4/tcp_output.c:864
1) We send out a normal sized packet with TSO on to start off.
2) ICMP is received indicating a smaller MTU.
3) We send the current sk_send_head which needs to be fragmented
since it was created before the ICMP event. The first fragment
is then sent out.
At this point the remaining fragment is allocated by tcp_fragment.
However, its size is padded to fit the L1 cache-line size therefore
creating tail-room up to 124 bytes long.
This fragment will also be sitting at sk_send_head.
4) tcp_sendmsg is called again and it stores data in the tail-room of
of the fragment.
5) tcp_push_one is called by tcp_sendmsg which then calls tso_fragment
since the packet as a whole exceeds the MTU.
At this point we have a packet that has data in the head area being
fed to tso_fragment which bombs out.
My take on this is that we shouldn't ever call tcp_fragment on a TSO
socket for a packet that is yet to be transmitted since this creates
a packet on sk_send_head that cannot be extended.
So here is a patch to change it so that tso_fragment is always used
in this case.

This allows us to keep the devt_attr alive while the corresponding

On the 6700/6702 PXH part, a MSI may get corrupted if an ACPI hotplug
driver and SHPC driver in MSI mode are used together.
This patch will prevent MSI from being enabled for the SHPC as part of
an early pci quirk, as well as on any pci device which sets the no_msi
bit.

Subject: [PATCH 271/997] [PATCH] iSeries build with newer assemblers and
compilers
Paulus suggested that we put xLparMap in its own .c file so that we can
generate a .s file to be included into head.S. This doesn't get around
the problem of having it at a fixed address, but it makes it more
palatable.
It would be good if this could be included in 2.6.13 as it solves our
build problems with various versions of binutils and gcc. In
particular, it allows us to build an iSeries kernel on Debian unstable
using their biarch compiler.
This has been built and booted on iSeries and built for pSeries and g5.

Subject: [PATCH 273/997] [ARM] 2850/1: Remove duplicate UART I/O mapping from
s3c2410_iodesc
Patch from Dimitry Andric
This patch removes the initial UART I/O mapping from s3c2410_iodesc,
since the same mapping is already done in the function s3c24xx_init_io
in the file arch/arm/mach-s3c2410/cpu.c, through the s3c_iodesc array.
I'm not sure if duplicate mappings do any harm, but it's simply
redundant. Also, in s3c2440.c the UART I/O mapping is NOT done.
Additionally, I put a comma behind the last mapping, to ease
copy/pasting stuff around, and make the style consistent with
s3c2440.c and other files.

When packets hit raw sockets the csum update isn't done yet, do it manually.
Packets can also reach rawv6_rcv on the output path through
ip6_call_ra_chain, in this case skb->ip_summed is CHECKSUM_NONE and this
codepath isn't executed.

Subject: [PATCH 277/997] [TCP]: Fix bug #5070: kernel BUG at
net/ipv4/tcp_output.c:864
1) We send out a normal sized packet with TSO on to start off.
2) ICMP is received indicating a smaller MTU.
3) We send the current sk_send_head which needs to be fragmented
since it was created before the ICMP event. The first fragment
is then sent out.
At this point the remaining fragment is allocated by tcp_fragment.
However, its size is padded to fit the L1 cache-line size therefore
creating tail-room up to 124 bytes long.
This fragment will also be sitting at sk_send_head.
4) tcp_sendmsg is called again and it stores data in the tail-room of
of the fragment.
5) tcp_push_one is called by tcp_sendmsg which then calls tso_fragment
since the packet as a whole exceeds the MTU.
At this point we have a packet that has data in the head area being
fed to tso_fragment which bombs out.
My take on this is that we shouldn't ever call tcp_fragment on a TSO
socket for a packet that is yet to be transmitted since this creates
a packet on sk_send_head that cannot be extended.
So here is a patch to change it so that tso_fragment is always used
in this case.

Subject: [PATCH 280/997] [PATCH] NPTL signal delivery deadlock fix
This bug is quite subtle and only happens in a very interesting
situation where a real-time threaded process is in the middle of a
coredump when someone whacks it with a SIGKILL. However, this deadlock
leaves the system pretty hosed and you have to reboot to recover.
Not good for real-time priority-preemption applications like our
telephony application, with 90+ real-time (SCHED_FIFO and SCHED_RR)
processes, many of them multi-threaded, interacting with each other for
high volume call processing.

The nfsd holds the big kernel lock upon exit, when it really shouldn't.
Not to mention that this breaks Ingo's RT patch. This is a trivial fix
to release the lock.
Ingo, this patch also works with your kernel, and stops the problem with
nfsd.
Note, there's a "goto out;" where "out:" is right above svc_exit_thread.
The point of the goto also holds the kernel_lock, so I don't see any
problem here in releasing it.

It turns out that empty distance code tables are not an error, and that
a compressed block with only literals can validly have an empty table
and should not be flagged as a data error.
Some old versions of gzip had problems with this case, but it does not
affect the zlib code in the kernel.

Subject: [PATCH 285/997] [IA64-SGI] - New SN hardware support - addr_macros
Update the SN address macros so that they work on both shub1
and shub2. Most of the code to support shub2 was added last year
but this patch fixes a few bugs and adds macros to help generate
both processor-specific physical addresses & numalink physical
addresses. More cleanup & optimization will be done later.

that use the BTE engine, to the MMR addresses of various
shub registers, and to using the correct processor or network

Subject: [PATCH 291/997] [IA64-SGI] - New SN hardware support - ptc_fixes
Shub2 provides a much improved mechanism for issuing internode
TLB purges. Add code to support the newer mechanism. There is also
some debug code (disabled) that is useful for testing.
Collect statistics on the number, type & duration of TLB purges.
This data will be useful for making future improvements in the algorithms.

Subject: [PATCH 292/997] [PATCH] Fix manual binding infinite loop
Fix for manual binding of drivers to devices. Problem is if you pass in
a valid device id, but the driver refuses to bind. Infinite loop as
write() tries to resubmit the data it just sent.
Thanks to Michal Ostrowski <mostrows@watson.ibm.com> for pointing the
problem out.

Subject: [PATCH 296/997] [PATCH] broken error path in drivers/pnp/card.c
The error path in pnp_request_card_device() is broken (one variable is
left initialized and the semaphore is not unlocked).
This fixes it (and has been tested).

Subject: [PATCH 298/997] [PATCH] NFS: split nfsi->flags into two fields
Certain bits in nfsi->flags can be manipulated with atomic bitops, and some
are better manipulated via logical bitmask operations.
This patch splits the flags field into two. The next patch introduces atomic
bitops for one of the fields.
Test plan:
Millions of fsx ops on SMP clients.

Subject: [PATCH 299/997] [PATCH] NFS: use atomic bitops to manipulate flags in
nfsi->flags
Introduce atomic bitops to manipulate the bits in the nfs_inode structure's
"flags" field.
Using bitops means we can use a generic wait_on_bit call instead of an ad hoc
locking scheme in fs/nfs/inode.c, so we can remove the "nfs_i_wait" field from
nfs_inode at the same time.
The other new flags field will continue to use bitmask and logic AND and OR.
This permits several flags to be set at the same time efficiently. The
following patch adds a spin lock to protect these flags, and this spin lock
will later cover other fields in the nfs_inode structure, amortizing the cost
of using this type of serialization.
Test plan:
Millions of fsx ops on SMP clients.

Subject: [PATCH 300/997] [PATCH] NFS: Introduce the use of inode->i_lock to
protect fields in nfsi
Down the road we want to eliminate the use of the global kernel lock entirely
from the NFS client. To do this, we need to protect the fields in the
nfs_inode structure adequately. Start by serializing updates to the
"cache_validity" field.
Note this change addresses an SMP hang found by njw@osdl.org, where processes
deadlock because nfs_end_data_update and nfs_revalidate_mapping update the
"cache_validity" field without proper serialization.
Test plan:
Millions of fsx ops on SMP clients. Run Nick Wilson's breaknfs program on
large SMP clients.

Subject: [PATCH 303/997] [PATCH] md: make sure mddev->bitmap_offset gets
cleared between array instantiations.
... otherwise we might try to load a bitmap from an array which hasn't one.
The bug is that if you create an array with an internal bitmap, shut it down,
and then create an array with the same md device, the md drive will assume it
should have a bitmap too. As the array can be created with a different md
device, it is mostly an inconvenience. I'm pretty sure there is no risk of
data corruption.

Subject: [PATCH 313/997] [PATCH] ide: fix the BLK_DEV_IDEDMA_PCI dependency
for drivers/ide/ppc/pmac.c
drivers/ide/ppc/pmac.c uses symbols ide_build_sglist,
__ide_dma_off_quietly, __ide_dma_on and __ide_dma_timeout when
CONFIG_BLK_DEV_IDEDMA_PMAC is defined. The declarations for these
symbols (in ide.h) depend on CONFIG_BLK_DEV_IDEDMA_PCI. There is a
missing dependency for this in drivers/ide/Kconfig which causes
drivers/ide/ppc/pmac.c to fail to build if CONFIG_BLK_DEV_IDEDMA_PMAC
is selected but CONFIG_BLK_DEV_IDEDMA_PCI is not.

BCM5785 (HT1000) is a Opteron Southbridge from Serverworks/Broadcom that
incorporates a single channel ATA100 IDE controller that is functionally
identical to the Serverworks CSB6 IDE controller. This patch adds support
for the new PCI device ID and also the support for this controller.

Subject: [PATCH 318/997] [PATCH] IOC3 fixes
- Using the right register clearly improves chances of getting the MII
code and thus the driver working at all.
- On startup check the media type before setting up duplex or we might
spend the first 1.2s with a wrong duplex setting.
- Get rid of whitespace lines.

Subject: [PATCH 320/997] [PATCH] DM9000 - spinlock fixes
Fix DM9000 driver usage of spinlocks, which mainly came to light
when running a kernel with spinlock debugging. These come down to:
1) Un-initialised spin lock
2) Several cases of using spin_xxx(lock) and not spin_xxx(&lock)
3) move the locking around the phy reg for read/write to only
keep the lock when actually reading or writing to the phy.

Subject: [PATCH 321/997] [PATCH] DM9000 - incorrect ioctl() handling
The DM9000 driver is responding to ioctl() calls it should not be. This
can cause problems with the wireless tools incorrectly indentifying the
device as wireless capable, and crashing under certain operations.
This patch also moves the version printk() to the init call, so that
you only get it once for multiple devices, and to show it is loaded
if there are no defined dm9000s

rif_lock.
Change operations on rif_lock from spin_{un}lock_bh to
spin_{un}lock_irq{save,restore} equivalents. Some of the
rif_lock critical sections are called from interrupt context via
tr_type_trans->tr_add_rif_info. The TR NIC drivers call tr_type_trans
from their packet receive handlers.

Subject: [PATCH 325/997] [IA64] Simulator bootloader fails with gcc 4 After
building a fresh tree with gcc 4 I can't boot the simulator as the bootloader
loader dies with
loading /home/ianw/kerntest/kerncomp//build/sim_defconfig/vmlinux...
failed to read phdr
After some investigation I believe this is do with differences between
the alignment of variables on the stack between gcc 3 and 4 and the
ski simulator. If you trace through with the simulator you can see
that the disk_stat structure value returned from the SSC_WAIT_COMPLETION
call seems to be only half loaded. I guess it doesn't like the alignment
of the input.

Subject: [PATCH 329/997] [IA64, X86_64] fix swiotlb sizing
Fix swiotlb sizing to match what the comments and the kernel
parameters documentation indicate. Given a default 16k page size kernel
(ia64) and a 2k swiotlb page size, we're off by a multiple of 8 trying
to size the swiotlb. When specified on the boot line, the swiotlb is
made 8x bigger than requested. When left to the default value, it's 8x
smaller than the comments indicate. For x86_64 the multiplier would be
2x. The patch below fixes this. Now, what's a good default swiotlb
size? Apparently we don't really need 64MB.

Subject: [PATCH 330/997] [PATCH] forcedeth: Initialize link settings in every
nv_open()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Rüdiger found a bug in nv_open that explains some of the reports
with duplex mismatches:
nv_open calls nv_update_link_speed for initializing the hardware link speed
registers. If current link setting matches the values in np->linkspeed and
np->duplex, then the function does nothing.
Usually, doing nothing is the right thing, but not in nv_open: During
nv_open, the registers must be initialized because the nic was reset.
The attached patch fixes that by setting np->linkspeed to an invalid value
before calling nv_update_link_speed from nv_open.

Subject: [PATCH 342/997] [TG3]: Fix SerDes detection
A problem was reported by Grant Grundler on an HP rx8620 using IOX
Core LAN partno(A7109-6) 5701 copper NIC. The tg3 driver mistakenly
detects this NIC as having a SerDes PHY and link does not come up as a
result.
The problem was caused by an incorrectly programmed eeprom that set the
NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit in the NIC_SRAM_DATA_CFG location.
This patch will override the NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit if a
valid PHY ID is read from the MII registers on older 570x chips where
the MII interface is not used on SerDes chips. On newer chips such as
the 5780 that use MII for both copper and SerDes, SerDes detection must
rely on the eeprom.
This patch will make the SerDes detection identical to versions 3.25 and
older.

Subject: [PATCH 346/997] [SPARC]: Fix weak aliases
sparc_ksyms.c used to declare weak alias to several gcc intrinsics. It
doesn't work with gcc4 anymore - it wants a declaration for the thing
we are aliasing to and that's not going to happen for something like
.mul, etc. Replaced with direct injection of weak alias on the assembler
level - .weak <alias> followed by <alias> = <aliased>; that works on all
gcc versions.

Subject: [PATCH 347/997] [PATCH] jffs2: fix symlink error handling
The current calling conventions for ->follow_link() are already fairly
complex.
What we have is
1) you can return -error; then you must release nameidata yourself
and ->put_link() will _not_ be called.
2) you can do nd_set_link(nd, ERR_PTR(-error)) and return 0
3) you can do nd_set_link(nd, path) and return 0
4) you can return 0 (after having moved nameidata yourself)
jffs2 follow_link() is broken - it has an exit where it returns
-EIO and leaks nameidata.

Subject: [PATCH 348/997] Fix nasty ncpfs symlink handling bug.
This bug could cause oopses and page state corruption, because ncpfs
used the generic page-cache symlink handlign functions. But those
functions only work if the page cache is guaranteed to be "stable", ie a
page that was installed when the symlink walk was started has to still
be installed in the page cache at the end of the walk.
We could have fixed ncpfs to not use the generic helper routines, but it
is in many ways much cleaner to instead improve on the symlink walking
helper routines so that they don't require that absolute stability.
We do this by allowing "follow_link()" to return a error-pointer as a
cookie, which is fed back to the cleanup "put_link()" routine. This
also simplifies NFS symlink handling.

From 84c3ea01d163a24323d827e1d280dc3346905972 Mon Sep 17 00:00:00 2001
From: Jochen Friedrich <jochen@scram.de>
Date: Fri, 19 Aug 2005 21:05:56 -0400
Subject: [PATCH 349/997] [netdrvr] Convert madgemc to new MCA API.
Now that all tms380 devices have a valid
struct device with dma_mask, remove dmalimit from tmsdev_init().
Kconfig: depend tms380tr and madgemc on MCA.
abyss.c, proteon.c, skisa.c, tmspci.c, tms380tr.h:
remove dmalimit parameter from tmsdev_init().
tms380tr.c: use device->dma_mask instead of dmalimit.
madgemc.c: move to new MCA API using struct device.

Subject: [PATCH 352/997] [PATCH] S2io: Hardware fixes for Xframe II adapter
Hi,
Patch Description:
This patch incorporates the following hardware fixes required
for Xframe II adapter.
1. New values to program the dtx_control register.
2. Disable memory controller interrupts(MC_INTR) since these
are now monitored thru' a poll routine.
3. Don't reset an XframeII card on an ECC double-bit error(It
can recover).
4. Save/restore PCI config space before/after a reset irrespective
of Xframe I or II card.
5. Bumped up the driver version no. to 2.0.3.1
Please review the patch and apply the same if it looks ok.

Subject: [PATCH 353/997] [PATCH] Mobil Pentium 4 HT and the NMI
I'm trying to get the nmi working with my laptop (IBM ThinkPad G41) and after
debugging it a while, I found that the nmi code doesn't want to set it up for
this particular CPU.
Here I have:
$ cat /proc/cpuinfo

monitor ds_cpl est tm2 cid xtpr
bogomips : 6637.46
And the following code shows:
$ cat linux-2.6.13-rc6/arch/i386/kernel/nmi.c
[...]
void setup_apic_nmi_watchdog (void)
{
switch (boot_cpu_data.x86_vendor) {
case X86_VENDOR_AMD:
if (boot_cpu_data.x86 != 6 && boot_cpu_data.x86 != 15)
return;
setup_k7_watchdog();
break;
case X86_VENDOR_INTEL:
switch (boot_cpu_data.x86) {
case 6:
if (boot_cpu_data.x86_model > 0xd)
return;
setup_p6_watchdog();
break;
case 15:
if (boot_cpu_data.x86_model > 0x3)
return;
Here I get boot_cpu_data.x86_model == 0x4. So I decided to change it and
reboot. I now seem to have a working NMI. So, unless there's something know
to be bad about this processor and the NMI. I'm submitting the following
patch.

Subject: [PATCH 356/997] [PATCH] x86_64: Fix race in TSC synchronization
Plug a race in TSC synchronization
We need to do tsc_sync_wait() before the CPU is set online to prevent
multiple CPUs from doing it in parallel - which won't work because TSC
sync has global unprotected state.

Subject: [PATCH 367/997] drm: fix a bad VERSION check.
I found why my G5 was crashing when using the linux-2.6 version of the
DRM + git-drm.patch from 2.6.13-rc6-mm1, but not with the CVS DRM.
The reason was that dev->agp->cant_use_aperture wasn't getting set,
and the reason for that was that <linux/version.h> no longer gets
included and the #if LINUX_VERSION_CODE < 0x020408 in drm_agpsupport.c
was going the wrong way. With this patch (and a few others) a 32-bit
server works correctly, as does DRI.

Subject: [PATCH 369/997] [PATCH] libata: Clear ATA_QCFLAG_ACTIVE flag before
calling the completion callback
Description:
After calling the completion callback, the libata error handler might be
running and getting atapi sense data. Clearing the ATA_QCFLAG_ACTIVE flag
at this point might interfere with the libata error handler.
Changes:
- Clear the ATA_QCFLAG_ACTIVE flag before calling the completion callback
(and also before the error handler)
- Add some comment

Subject: [PATCH 372/997] [PATCH] Fix HD activity LED with ahci
Patch: fix wrong HD activity control by ahci driver
The ahci driver 1.0 sets the SActive bit on every transaction,
causing the LED to light up. The SActive bit is used only for
native command queuing (NCQ) which the current driver version
doesn't implement. Resetting the SActive bit is the device's
responsibility (by sending a "Set Device Bits FIS" to the
host adapter) but this is not required in response to
non-NCQ commands, and (most) devices don't. Thus the LED
stays always on. This patch fixes the LED behavior.

Subject: [PATCH 373/997] [PATCH] fix atapi_packet_task vs. intr race (take 2)
Interrupts from devices sharing the same IRQ could cause
ata_host_intr to finish commands being processed by atapi_packet_task
if the commands are using ATA_PROT_ATAPI_NODATA or ATA_PROT_ATAPI_DMA
protocol. This is because libata interrupt handler is unaware that
interrupts are not expected during that period. This patch adds
ATA_FLAG_NOINTR flag to tell the interrupt handler that we're not
expecting interrupts.
Note that once proper HSM is implemented for interrupt-driven PIO,
this should be merged into it and this flag will be removed.
ahci.c is a different kind of beast, so it's left alone.
* The following drivers use ata_qc_issue_prot and ata_interrupt, so
changes in libata core will do.
ata_piix sata_sil sata_svw sata_via sata_sis sata_uli
* The following drivers use ata_qc_issue_prot and custom intr handler.
They need this change to work correctly.
sata_nv sata_vsc
* The following drivers use custom issue function and intr handler.
Currently all custom issue functions don't support ATAPI, so this
change is irrelevant, updated for consistency and to avoid later
mistakes.

Subject: [PATCH 374/997] [PATCH] libata: implement ata_poll_qc_complete and
use it in polling functions
[PATCH libata-dev-2.6:upstream] implement ata_poll_qc_complete and use it in polling functions
Previously, libata polling functions turned irq back on and completed
qc commands without holding host lock. This creates a race condition
between the polling task and interrupts from other ports on the same
host set or spurious interrupt from itself.
This patch implements ata_poll_qc_complete which enables irq and
completes qc atomically and convert all polling functions.
Note: atapi_packet_task() didn't use to turn irq back on or clear
ATA_FLAG_NOINTR on error exits. This patch makes it use
ata_poll_qc_complete which does both.
Note: With this change, ALL invocations of ata_qc_complete() are now
done under host_set lock.

As SII reports that only original 3112's are affected by M15W quirk,
This patch adds SIL_FLAG_MOD15WRITE to selectively apply M15W quirk
depending on chipsets. As of yet, we don't know exactly which PCI IDs
are for original 3112, so M15W quirk is applied to all except for 3512
and 3124. Once more info is avaliable, we can change some of these
sil_3112_m15w's to sil_3112.

Subject: [PATCH 376/997] [PATCH] macsonic/jazzsonic network drivers update
The purpose of this patch:
- Adopt the DMA API (jazzsonic, macsonic & core driver).
- Adopt the driver model (macsonic).
This part was cribbed from jazzsonic. As a consequence, macsonic once
again works as a module. Driver model is also used by the DMA calls.
- Support 16 bit cards (macsonic & core driver, also affects jazzsonic)
This code was adapted from the mac68k linux 2.2 kernel, where it has
languished for a long time.
- Support more 32-bit mac cards (macsonic)
Also from mac68k repo.
- Zero-copy buffer handling (core driver)
Provides a nice performance improvement. The new algorithm incidentally
helped to replace the old Jazz DMA code.
The patch was tested on a variety of macs (several 32-bit quadra built-in
NICs, a 16-bit LC PDS NIC and a 16-bit comm-slot NIC), and also on MIPS
Jazz.

Subject: [PATCH 377/997] [PATCH] bonding: inherit zero-copy flags of slaves
This change allows a bonding device to inherit the "zero-copy"
features of its slave devices.
It was inspired by a couple of previous postings on this topic:
http://marc.theaimsgroup.com/?l=bonding-devel&m=111924607327794&w=2
http://marc.theaimsgroup.com/?l=bonding-devel&m=111925242706297&w=2
and it's largely a combination of the patches that appear in those
emails.

Subject: [PATCH 381/997] [IA64] Fix simulator boot (for real this time).
Thanks to Stephane, we've now worked out the real cause of the
`Linux will not boot on simulator' problem. Turns out it's a stack
overflow because the stack pointer wasn't being initialised properly
in boot_head.S (it was being initialised to the lowest instead of the
highest address of the stack, so the first push started to overwrite
data in the BSS).

Subject: [PATCH 382/997] [TCP]: Do TSO deferral even if tail SKB can go out
now.
If the tail SKB fits into the window, it is still
benefitical to defer until the goal percentage of
the window is available. This give the application
time to feed more data into the send queue and thus
results in larger TSO frames going out.

While I was going through the crypto users recently, I noticed this
bogus kmap in sunrpc. It's totally unnecessary since the crypto
layer will do its own kmap before touching the data. Besides, the
kmap is throwing the return value away.

Subject: [PATCH 384/997] [IPV4]: Fix negative timer loop with lots of ipv4
peers.
From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com>
Found this bug while doing some scaling testing that created 500K inet
peers.
peer_check_expire() in net/ipv4/inetpeer.c isn't using inet_peer_gc_mintime
correctly and will end up creating an expire timer with less than the
minimum duration, and even zero/negative if enough active peers are
present.
If >65K peers, the timer will be less than inet_peer_gc_mintime, and with
>70K peers, the timer duration will reach zero and go negative.
The timer handler will continue to schedule another zero/negative timer in
a loop until peers can be aged. This can continue for at least a few
minutes or even longer if the peers remain active due to arriving packets
while the loop is occurring.
Bug is present in both 2.4 and 2.6. Same patch will apply to both just
fine.

Subject: [PATCH 386/997] [NET]: Fix socket bitop damage
The socket flag cleanups that went into 2.6.12-rc1 are basically oring
the flags of an old socket into the socket just being created.
Unfortunately that one was just initialized by sock_init_data(), so already
has SOCK_ZAPPED set. As the result zapped sockets are created and all
incoming connection will fail due to this bug which again was carefully
replicated to at least AX.25, NET/ROM or ROSE.
In order to keep the abstraction alive I've introduced sock_copy_flags()
to copy the socket flags from one sockets to another and used that
instead of the bitwise copy thing. Anyway, the idea here has probably
been to copy all flags, so sock_copy_flags() should be the right thing.
With this the ham radio protocols are usable again, so I hope this will
make it into 2.6.13.

Subject: [PATCH 387/997] [AX25]: UID fixes
o Brown paperbag bug - ax25_findbyuid() was always returning a NULL pointer
as the result. Breaks ROSE completly and AX.25 if UID policy set to deny.
o While the list structure of AX.25's UID to callsign mapping table was
properly protected by a spinlock, it's elements were not refcounted
resulting in a race between removal and usage of an element.

Subject: [PATCH 389/997] [PKT_SCHED]: Fix missing qdisc_destroy() in
qdisc_create_dflt()
qdisc_create_dflt() is missing to destroy the newly allocated
default qdisc if the initialization fails resulting in leaks
of all kinds. The only caller in mainline which may trigger
this bug is sch_tbf.c in tbf_create_dflt_qdisc().
Note: qdisc_create_dflt() doesn't fulfill the official locking
requirements of qdisc_destroy() but since the qdisc could
never be seen by the outside world this doesn't matter
and it can stay as-is until the locking of pkt_sched
is cleaned up.

Subject: [PATCH 390/997] [TCP]: Unconditionally clear TCP_NAGLE_PUSH in
skb_entail().
Intention of this bit is to force pushing of the existing
send queue when TCP_CORK or TCP_NODELAY state changes via
setsockopt().
But it's easy to create a situation where the bit never
clears. For example, if the send queue starts empty:
1) set TCP_NODELAY
2) clear TCP_NODELAY
3) set TCP_CORK
4) do small write()
The current code will leave TCP_NAGLE_PUSH set after that
sequence. Unconditionally clearing the bit when new data
is added via skb_entail() solves the problem.

We ran into the limit with the maximum number of waiters at one of our sites.
This patch increases the number of possible waiters from 2^15 to 2^31 by using
a long for the counter in struct rw_semaphore. S390 and alpha already do this.

Subject: [PATCH 394/997] [PATCH] preempt race in getppid
With CONFIG_PREEMPT && !CONFIG_SMP, it's possible for sys_getppid to
return a bogus value if the parent's task_struct gets reallocated after
current->group_leader->real_parent is read:
asmlinkage long sys_getppid(void)
{
int pid;
struct task_struct *me = current;
struct task_struct *parent;
parent = me->group_leader->real_parent;
RACE HERE => for (;;) {
pid = parent->tgid;
#ifdef CONFIG_SMP
{
struct task_struct *old = parent;
/*
* Make sure we read the pid before re-reading the
* parent pointer:
*/
smp_rmb();
parent = me->group_leader->real_parent;
if (old != parent)
continue;
}
#endif
break;
}
return pid;
}
If the process gets preempted at the indicated point, the parent process
can go ahead and call exit() and then get wait()'d on to reap its
task_struct. When the preempted process gets resumed, it will not do any
further checks of the parent pointer on !CONFIG_SMP: it will read the
bad pid and return.
So, the same algorithm used when SMP is enabled should be used when
preempt is enabled, which will recheck ->real_parent in this case.

Subject: [PATCH 395/997] [PATCH] md: make sure resync gets started when array
starts.
We weren't actually waking up the md thread after setting
MD_RECOVERY_NEEDED when assembling an array, so it is possible to lose a
race and not actually start resync.
So add a call to md_wakeup_thread, and while we are at it, remove all the
"if (mddev->thread)" guards as md_wake_thread does its own checking.

Subject: [PATCH 428/997] [PATCH] m32r icu_data gcc4 fixes
either icu_data declaration for SMP case should be taken out of m32102.h,
or its declarations for m32700ut and opsput should not be static for SMP.
Patch does the latter - judging by comments in m32102.h it is intended to
be non-static.

Subject: [PATCH 441/997] [PATCH] i386: fix incorrect FP signal code
i386 floating-point exception handling has a bug that can cause error
code 0 to be sent instead of the proper code during signal delivery.
This is caused by unconditionally checking the IS and c1 bits from the
FPU status word when they are not always relevant. The IS bit tells
whether an exception is a stack fault and is only relevant when the
exception is IE (invalid operation.) The C1 bit determines whether a
stack fault is overflow or underflow and is only relevant when IS and IE
are set.

The code to detect IO links on Opteron would not check

returning an invalid node, which might cause crashes later
when dma_alloc_coherent passes it to page_alloc_node().
The bug has been there forever but for some reason
it is causing now crashes.

Subject: [PATCH 444/997] [PATCH] cpu_exclusive sched domains on partial nodes
temp fix
This keeps the kernel/cpuset.c routine update_cpu_domains() from
invoking the sched.c routine partition_sched_domains() if the cpuset in
question doesn't fall on node boundaries.
I have boot tested this on an SN2, and with the help of a couple of ad
hoc printk's, determined that it does indeed avoid calling the
partition_sched_domains() routine on partial nodes.
I did not directly verify that this avoids setting up bogus sched
domains or avoids the oops that Hawkes saw.
This patch imposes a silent artificial constraint on which cpusets can
be used to define dynamic sched domains.
This patch should allow proceeding with this new feature in 2.6.13 for
the configurations in which it is useful (node alligned sched domains)
while avoiding trying to setup sched domains in the less useful cases
that can cause the kernel corruption and oops.

Subject: [PATCH 445/997] [PATCH] Fix IXP4xx CLOCK_TICK_RATE
As pointed out in the following thread, the CLOCK_TICK_RATE setting for
IXP4xx is incorrect b/c the HW ignores the lowest 2 bits of the LATCH
value.
http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2005-August/030950.html
Tnx to George Anziger and Egil Hjelmeland for finding the issue.

Subject: [PATCH 447/997] [FIB_TRIE]: Don't ignore negative results from
fib_semantic_match
When a semantic match occurs either success, not found or an error
(for matching unreachable routes/blackholes) is returned. fib_trie
ignores the errors and looks for a different matching route. Treat
results other than "no match" as success and end lookup.

Subject: [PATCH 449/997] [PATCH] cpu_exclusive sched domains build fix
As reported by Paul Mackerras <paulus@samba.org>, the previous patch
"cpu_exclusive sched domains fix" broke the ppc64 build with
CONFIC_CPUSET, yielding error messages:
kernel/cpuset.c: In function 'update_cpu_domains':
kernel/cpuset.c:648: error: invalid lvalue in unary '&'
kernel/cpuset.c:648: error: invalid lvalue in unary '&'
On some arch's, the node_to_cpumask() is a function, returning
a cpumask_t. But the for_each_cpu_mask() requires an lvalue mask.
The following patch fixes this build failure by making a copy
of the cpumask_t on the stack.

This patch puts back the export of machine_power_off() that was removed
by some janitor as it's used for emergency shutdown by the G5 thermal
control driver. Wether that driver should use kernel_power_off() instead
is debatable and a post-2.6.13 decision. In the meantime, please commit
that patch that fixes the driver for now.

One critical fix and two minor fixes for 2.6.13-rc7:
- Max depth must currently be 2 to allow barriers to function on SCSI
- Prefer sync request over async in choosing the next request
- Never allow async request to preempt or disturb the "anticipation" for
a single cfq process context. This is as-designed, the code right now
is buggy in that area.

Subject: [PATCH 456/997] [IA64] fix IO_SPACE_SPARSE_ENCODING macro ambiguity
Parenthesize "p" to avoid ambiguity. No callers have a problem today;
this is just to clean up the bad form.

Subject: [PATCH 457/997] [IA64] Rationalise Region Definitions
Currently, region numbers are defined in several files, with several
names. For example, we have REGION_KERNEL in asm/page.h and
RGN_KERNEL in pgtable.h
We also have address definitions that should depend on the
RGN_XXX macros, but are currently just long constants.
The following patch reorganises all the definitions so that they have
the same form (RGN_XXX), are in one place, and that addresses that
depend on RGN_XXX are derived from them.
(This is a necessary but not sufficient patch to allow UML-like
operation on IA64).
Thanks to David Mosberger for catching the change I missed in mmu_context.h.

Subject: [PATCH 469/997] [TG3]: Fix ethtool loopback test lockup
The tg3_abort_hw() call in tg3_test_loopback() is causing lockups on
some devices. tg3_abort_hw() disables the memory arbiter, causing
tg3_reset_hw() to hang when it tries to write the pre-reset signature.
tg3_abort_hw() should only be called after the pre-reset signature has
been written. This is all done in tg3_reset_hw() so the tg3_abort_hw()
call is unnecessary and can be removed.
[ Also bump driver version and release date. -DaveM ]

I had a problem where doing an open after a close left the device
unusable. netif_carrier_on should be called whenever we go to the
associated state, but this is not so in case of a close->open sequence.

only makes the code adhere to the comment, it seems to fix a boot-time
lockup on a ThinkPad 380XD laptop reported by Tero Roponen <teanropo@cc.jyu.fi>

Subject: [PATCH 485/997] Ignore disabled ROM resources at setup
Writing even a disabled value seems to mess up some matrox graphics
cards. It may be a card-related issue, but we may also be writing
reserved low bits in the result.
This was a fall-out of switching x86 over to the generic PCI resource
allocation code, and needs more debugging. In particular, the old x86
code defaulted to not doing any resource allocations at all for ROM
resources.
In the meantime, this has been reported to make X happier by Helge
Hafting <helgehaf@aitel.hist.no>.

Subject: [PATCH 486/997] [PATCH] Document idr_get_new_above() semantics,
update inotify
There is an off by one problem with idr_get_new_above.
The comment and function name suggest that it will return an id >
starting_id, but it actually returned an id >= starting_id, and kernel
callers other than inotify treated it as such.
The patch below fixes the comment, and fixes inotifys usage. The
function name still doesn't match the behaviour, but it never did.

While touching this code I noticed the error handling is bogus, so I

I've removed the IS_ERR(proc_dentry) check, which will never trigger and
is clearly a typo: we must check proc_file instead.

Subject: [PATCH 492/997] [IA64-SGI] fix bte_copy() calling smp_processor_id()
while preemptible
bte_copy() calls calls smp_processor_id(), which will get flagged if
preemption if enabled. raw_smp_processor_id() is used instead
because we are just using it to pick a BTE interface and are not
tied to a specific cpu.

Subject: [PATCH 493/997] [IA64] Add ACPI based P-state support
Patch to support P-state transitions on ia64. This driver is based on ACPI,
and uses the ACPI processor driver interface to find out the P-state support
information for the processor. This driver plugs into generic cpufreq
infrastructure.
Once this driver is loaded successfully, ondemand/userspace governor can be
used to change the CPU frequency dynamically based on load or on request from
userspace process.

ACPI specification -
http://www.acpi.info

Subject: [PATCH 494/997] [IA64] Delete erroneous copy_page.o in global lib-y
list
copy_page.o appeared twice in arch/ia64/lib/Makefile. The
one in global lib-y is wrong where it should be just in
lib-$(CONFIG_ITANIUM).
Both copy_page.o and copy_page_mck.o are build for Itanium2
processor and the link order will pick up the low performing
copy_page function (originally written for itanium processor).
In this case, we really want the copy_page_mck.o for optimized
version.

Subject: [PATCH 495/997] [PATCH] Fix oops in fs/locks.c on close of file with
pending locks
The recent change to locks_remove_flock code in fs/locks.c changes how
byte range locks are removed from closing files, which shows up a bug in
cifs.
The assumption in the cifs code was that the close call sent to the
server would remove any pending locks on the server on this file, but
that is no longer safe as the fs/locks.c code on the client wants unlock
of 0 to PATH_MAX to remove all locks (at least from this client, it is
not possible AFAIK to remove all locks from other clients made to the
server copy of the file).
Note that cifs locks are different from posix locks - and it is not
possible to map posix locks perfectly on the wire yet, due to
restrictions of the cifs network protocol, even to Samba without adding
a new request type to the network protocol (which we plan to do for
Samba 3.0.21 within a few months), but the local client will have the
correct, posix view, of the lock in most cases.
The correct fix for cifs for this would involve a bigger change than I
would like to do this late in the 2.6.13-rc cycle - and would involve
cifs keeping track of all unmerged (uncoalesced) byte range locks for
each remote inode and scanning that list to remove locks that intersect
or fall wholly within the range - locks that intersect may have to be
reaquired with the smaller, remaining range.

I recently had a BUG_ON() go off spuriously on a gcc 4.0 compiled kernel.
It turns out gcc-4.0 was removing a sign extension while earlier gcc
versions would not. Thinking this to be a compiler bug, I submitted a
report:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23422
It turns out we need to cast the input in order to tell gcc to sign extend
it.
Thanks to Andrew Pinski for his help on this bug.

Subject: [PATCH 506/997] [PATCH] I2C hwmon: kfree fixes
This patch fixes several instances of hwmon drivers kfree'ing the "wrong"
pointer; the existing code works somewhat by accident.
(akpm: plucked from Greg's queue based on lkml discussion. Finishes off the
patch from Jon Corbet)

Subject: [PATCH 507/997] [PATCH] x86_64: Tell VM about holes in nodes
Some nodes can have large holes on x86-64.
This fixes problems with the VM allowing too many dirty pages because it
overestimates the number of available RAM in a node. In extreme cases you
can end up with all RAM filled with dirty pages which can lead to deadlocks
and other nasty behaviour.
This patch just tells the VM about the known holes from e820. Reserved
(like the kernel text or mem_map) is still not taken into account, but that
should be only a few percent error now.
Small detail is that the flat setup uses the NUMA free_area_init_node() now
too because it offers more flexibility.
(akpm: lotsa thanks to Martin for working this problem out)

Subject: [PATCH 508/997] [PATCH] arm: fix IXP4xx flash resource range
We are currently reserving one byte more than actually needed by the flash
device and overlapping into the next I/O expansion bus window. This a)
causes us to allocate an extra page of VM due to ARM ioremap() alignment
code and b) could cause problems if another driver tries to request the
next expansion bus window.

Subject: [PATCH 512/997] [PATCH] Fix oops in sysfs_hash_and_remove_file()
The problem arises if an entity in sysfs is created and removed without
ever having been made completely visible. In SCSI this is triggered by
removing a device while it's initialising.
The problem appears to be that because it was never made visible in sysfs,
the sysfs dentry has a null d_inode which oopses when a reference is made
to it. The solution is simply to check d_inode and assume the object was
never made visible (and thus doesn't need deleting) if it's NULL.
(akpm: possibly a stopgap for 2.6.13 scsi problems. May not be the
long-term fix)

Subject: [PATCH 522/997] [PATCH] IB/mthca: Use correct port width capability
value
When we call the INIT_IB firmware command to bring up a port, use
the actual port width capability returned by the QUERY_DEV_LIM
command instead of always trying to enable both 1X and 4X. This
fixes breakage seen when the firmware is build to allow 4X only.

Add SRQ support to userspace verbs module. This adds several commands

ABI version because the commands are added at the end of the list so
they don't change the existing numbering. There are two cases to
worry about:
1. New kernel, old userspace. This is OK because old userspace simply
won't try to use the new SRQ commands. None of the old commands are
changed.
2. Old kernel, new userspace. This works perfectly as long as
userspace doesn't try to use SRQ commands. If userspace tries to
use SRQ commands, it will get EINVAL, which is perfectly
reasonable: the kernel doesn't support SRQs, so we couldn't do any
better.

From 87b816706bb2b79fbaff8e0b8e279e783273383e Mon Sep 17 00:00:00 2001
From: Roland Dreier <roland@eddore.topspincom.com>
Date: Thu, 18 Aug 2005 13:39:31 -0700
Subject: [PATCH 526/997] [PATCH] IB/mthca: Factor out common queue alloc code
Clean up the allocation of memory for queues by factoring out the
common code into mthca_buf_alloc() and mthca_buf_free(). Now CQs and
QPs share the same queue allocation code, which we'll also use for SRQs.

Subject: [PATCH 527/997] [PATCH] IB/mthca: Simplify handling of completions
with error
Mem-free HCAs never generate error CQEs that complete multiple WQEs,
so just skip the call to mthca_free_err_wqe() for them rather than
having logic to handle the mem-free case in mthca_free_err_wqe().

Subject: [PATCH 529/997] [PATCH] IB/mthca: Handle context tables smaller than
our chunk size
When creating a table in context memory where the table is smaller
than our chunk size, we don't want to allocate and map a full chunk.
Instead, allocate just enough memory to cover the table.
This can be pretty simple because all tables are a power-of-2 size, so
either the table is a multiple of the chunk size, or it's smaller than
one chunk.

Subject: [PATCH 531/997] [PATCH] IPoIB: Set full membership bit in P_Keys
Always make sure that the full membership bit is set in the P_Keys
that IPoIB uses. This makes sure that all hosts join the correct
multicast groups so that hosts that are partial partition members
can talk to the rest of the network.

Subject: [PATCH 532/997] [PATCH] IB: fix userspace CM deadlock
Fix deadlock condition resulting from trying to destroy a cm_id
from the context of a CM thread. The synchronization around the
ucm context structure is simplified as a result, and some simple
code cleanup is included.

Subject: [PATCH 534/997] [PATCH] IPoIB: Fix device removal race
Currently we may have work scheduled in default kernel workqueue when
the device is going down. The device could get freed before this
workqueue gets serviced. I am actually seeing this causing system
hangs.
The following patch fixes this by using ipoib_workqueue which gets
flushed when the device is going down.

Subject: [PATCH 535/997] [PATCH] IB: move include files to include/rdma
Move the InfiniBand headers from drivers/infiniband/include to include/rdma.
This allows InfiniBand-using code to live elsewhere, and lets us remove the
ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles.

Subject: [PATCH 537/997] [libata scsi] fix read/write translation edge cases
Fix bugs for unlikely edge cases noticed by Douglas Gilbert:
- When READ(6)/WRITE(6) sector count == 0, treat it as 256 sectors
- For other READ(x)/WRITE(x), when sector count == 0, error.
We don't support successfully completing zero-length transfers at
this time.

Subject: [PATCH 539/997] [PATCH] Fix 6pack setting of MAC address
Don't check type of sax25_family; dev_set_mac_address has already done
that before and anyway, the type to check against would have been
ARPHRD_AX25. We only got away because AF_AX25 and ARPHRD_AX25 both happen
to be defined to the same value.
Don't check sax25_ndigis either; it's value is insignificant for the
purpose of setting the MAC address and the check has shown to break
some application software for no good reason.

3 of the Linksys EG1032
Both revisions share the same PCI device ID and vendor ID but revision 2
of the device uses SysKonnect's chipset whereas revision 3 of the device
uses Realtek's 8169 chipset.
Credit goes to Christiaan Lutzer <mythtv.lutzer@gmail.com> for reporting
the issue and giving the actual value for the different revisions.

Subject: [PATCH 542/997] [PATCH] mmaper_kern.c fixes [buffer overruns]
- copy_from_user() can fail; ->write() must check its return value.
- severe buffer overruns both in ->read() and ->write() - lseek to the
end (i.e. to mmapper_size) and
if (count + *ppos > mmapper_size)
count = count + *ppos - mmapper_size;
will do absolutely nothing. Then it will call
copy_to_user(buf,&v_buf[*ppos],count);
with obvious results (similar for ->write()).
Fixed by turning read to simple_read_from_buffer() and by doing
normal limiting of count in ->write().
- gratitious lock_kernel() in ->mmap() - it's useless there.
- lots of gratuitous includes.

When acpi_sleep_prepare was moved into a shutdown method we

It appears this triggers some systems to power off on reboot.
Avoid this by only calling acpi_sleep_prepare if we are going to power
off the system.

then the transfer is enabled. Dibusb devices and clones are now fully

Subject: [PATCH 546/997] [PATCH] sg.c: fix a memory leak in devices seq_file
implementation
I know that scsi procfs is legacy code but this is a fix for a memory leak.
While reading through sg.c I realized that the implementation of
/proc/scsi/sg/devices with seq_file is leaking memory due to freeing the
pointer returned by the next() iterator method. Since next() might return
NULL or an error this is wrong. This patch fixes it through using the
seq_files private field for holding the reference to the iterator object.
Here is a small bash script to trigger the leak. Use slabtop to watch
the size-32 usage grow and grow.

Subject: [PATCH 548/997] [PATCH] Remove race between con_open and con_close
[ Same race and same patch also by Steven Rostedt <rostedt@goodmis.org> ]
I have a laptop (G3 powerbook) which will pretty reliably hit a race
between con_open and con_close late in the boot process and oops in
vt_ioctl due to tty->driver_data being NULL.
What happens is this: process A opens /dev/tty6; it comes into
con_open() (drivers/char/vt.c) and assign a non-NULL value to
tty->driver_data. Then process A closes that and concurrently process
B opens /dev/tty6. Process A gets through con_close() and clears
tty->driver_data, since tty->count == 1. However, before process A
can decrement tty->count, we switch to process B (e.g. at the
down(&tty_sem) call at drivers/char/tty_io.c line 1626).
So process B gets to run and comes into con_open with tty->count == 2,
as tty->count is incremented (in init_dev) before con_open is called.
Because tty->count != 1, we don't set tty->driver_data. Then when the
process tries to do anything with that fd, it oopses.
The simple and effective fix for this is to test tty->driver_data
rather than tty->count in con_open. The testing and setting of
tty->driver_data is serialized with respect to the clearing of
tty->driver_data in con_close by the console_sem. We can't get a
situation where con_open sees tty->driver_data != NULL and then
con_close on a different fd clears tty->driver_data, because
tty->count is incremented before con_open is called. Thus this patch
eliminates the race, and in fact with this patch my laptop doesn't
oops.

prism2_pccard_card_present()
With my Buffalo WLI-CF-S11G PC Card kernel oopses every time in
prism2_interrupt() when I try load the hostap module. local->hw_priv is null
during the first call to prism2_interrupt(). It feels like
interrupts are enabled too early, or something.
This patch fixes the symptom, but not the cause.

From e13934563db047043ccead26412f552375cea90c Mon Sep 17 00:00:00 2001
From: Andy Fleming <afleming@freescale.com>
Date: Wed, 24 Aug 2005 18:46:21 -0500
Subject: [PATCH 560/997] [PATCH] PHY Layer fixup
This patch adds back the code that was taken out, thus re-enabling:
* The PHY Layer to initialize without crashing
* Drivers to actually connect to PHYs
* The entire PHY Control Layer
This patch is used by the gianfar driver, and other drivers which are in
development.

From decd300b30e499fe6be1bbfc5650fc971de8c1fa Mon Sep 17 00:00:00 2001
From: Olaf Hering <olh@suse.de>
Date: Mon, 8 Aug 2005 13:24:38 +1000
Subject: [PATCH 561/997] [PATCH] ppc64: make arch/ppc64/boot standalone
Make the bootheader for ppc64 independent from kernel and libc headers.
* add -nostdinc -isystem $gccincludes to not include libc headers
* declare all functions in header files, also the stuff from string.S
* declare some functions static
* use stddef.h to get size_t (hopefully ok)
* remove ppc32-types.h, only elf.h used the __NN types
With further modifications by Paul Mackerras and Stephen Rothwell.

From e28f7faf05159f1cfd564596f5e6178edba6bd49 Mon Sep 17 00:00:00 2001
From: David Gibson <david@gibson.dropbear.id.au>
Date: Fri, 5 Aug 2005 19:39:06 +1000
Subject: [PATCH 562/997] [PATCH] Four level pagetables for ppc64
Implement 4-level pagetables for ppc64
This patch implements full four-level page tables for ppc64, thereby
extending the usable user address range to 44 bits (16T).
The patch uses a full page for the tables at the bottom and top level,
and a quarter page for the intermediate levels. It uses full 64-bit
pointers at every level, thus also increasing the addressable range of
physical memory. This patch also tweaks the VSID allocation to allow
matching range for user addresses (this halves the number of available
contexts) and adds some #if and BUILD_BUG sanity checks.

Subject: [PATCH 563/997] [PATCH] flattened device tree changes
This patch updates the format of the flattened device-tree passed
between the boot trampoline and the kernel to support a more compact
representation, for use by embedded systems mostly.

Subject: [PATCH 564/997] [PATCH] ppc64: PCI device-node failure detection
OpenFirmware marks devices as failed in the device-tree when a hardware
problem is detected. The kernel needs to fail config reads/writes to
prevent a kernel crash when incorrect data is read.
This patch validates that the device-node is not marked "fail" when
config space reads/writes are attempted.

Subject: [PATCH 565/997] [PATCH] ppc64: change duplicate Kconfig menu "General
setup" to "Bus Options"
arch/ppc64/Kconfig defines a "General setup" menu, but also sources
init/Kconfig which also defines a "General setup" menu. Both of these
menus appear at the top level of make menuconfig. Having two menus with
the same name is confusing. This patch renames the ppc64/Kconfig menu to
be "Bus Options" and moves options in this menu which are not bus related
to the end of the "Platform support" menu.
There are many variations among architectures on the exact naming of the
"Bus Options" menu. I chose to use the simplest one, which is also used
in arch/ppc/Kconfig.

Subject: [PATCH 567/997] [PATCH] ppc64: move iSeries vio iommu init
Since the iSeries vio iommu tables cannot be used until after the vio bus has
been initialised, move the initialisation of the tables to there.

From 2e2446ea0758cd57dd065962d9544e3f4d44ea2b Mon Sep 17 00:00:00 2001
From: David Gibson <david@gibson.dropbear.id.au>
Date: Fri, 19 Aug 2005 14:52:31 +1000
Subject: [PATCH 570/997] [PATCH] Remove NACA fixed address constraint
Comments in head.S suggest that the iSeries naca has a fixed address,
because tools expect to find it there. The only tool which appears to
access the naca is addRamDisk, but both the in-kernel version and the
version used in RHEL and SuSE in fact locate the NACA the same way as
the hypervisor does, by following the pointer in the hvReleaseData
structure.
Since the requirement for a fixed address seems to be obsolete, this
patch removes the naca from head.S and replaces it with a normal C
initializer.
For good measure, it removes an old version of addRamDisk.c which was
sitting, unused, in the ppc32 tree.

From ec465515eeb662f66725c8c483a46b6bdd9bdd48 Mon Sep 17 00:00:00 2001
From: David Gibson <david@gibson.dropbear.id.au>
Date: Fri, 19 Aug 2005 14:52:31 +1000
Subject: [PATCH 571/997] [PATCH] Move iSeries and common vectors into unused
space in head.S
In the ppc64 kernel head.S there is currently quite a lot of unused
space between the naca (at fixed address 0x4000) and the fwnmi data
area (at fixed address 0x7000). This patch moves various exception
vectors and support code into this region to use the wasted space.
The functions load_up_fpu and load_up_altivec are moved down as well,
since they are essentially continuations of the fp_unavailable_common
and altivec_unavailable_common vectors, respectively.
Likewise, the fwnmi vectors themselves are moved down into this area,
because while the location of the fwnmi data area is fixed by the RPA,
the vectors themselves can be anywhere sufficiently low.

Subject: [PATCH 572/997] [PATCH] Change address of ppc64 initial segment table
On ppc64 machines with segment tables, CPU0's segment table is at a
fixed address, currently 0x9000. This patch moves it to the free
space at 0x6000, just below the fwnmi data area. This saves 8k of
space in vmlinux and the runtime kernel image.

Subject: [PATCH 573/997] [PATCH] Remove general use functions from head.S
As well as the interrupt vectors and initialization code, head.S
contains several asm functions which are used during runtime. This
patch moves these to misc.S, a more sensible location for random asm
support code. A couple The functions moved are:
disable_kernel_fp
giveup_fpu
disable_kernel_altivec
giveup_altivec
__setup_cpu_power3 (empty function)

Subject: [PATCH 574/997] [PATCH] Fix apparent code overlap in ppc64 head.S
An #if/#else construct near the top of ppc64's head.S appears to
create overlapping sections of code for iSeries and pSeries (i.e. one
thing on iSeries and something different in the same place on
pSeries). In fact, checking the various absolute offsets, it doesn't.
This patch unravels the #ifdefs to make it more obvious what's going
on. This accomplishes another microstep towards a single kernel image
which can boot both iSeries and pSeries.

arch/ppc64/kernel/head.S #defines SECONDARY_PROCESSORS then has some

Likewise, head.S defines H_SET_ASR, which is now defined, along with
other hypervisor call numbers in hvcall.h. This patch deletes it, as
well, from head.S.

.bss
The ppc64 head.S defines several zero-initialized structures, such as
the empty_zero_page and the kernel top-level pagetable. Currently
they are defined to be in the data section. However, they're not used
until after the bss is cleared, so this patch moves them to the bss,
saving two and a half pages from the vmlinux.

Subject: [PATCH 578/997] [PATCH] ppc64: remove firmware features from cpu_spec
The firmware_features field of struct cpu_spec should really be a separate
variable as the firmware features do not depend on the chip and the
bitmask is constructed independently. By removing it, we save 112 bytes
from the cpu_specs array and we access the bitmask directly instead of via
the cur_cpu_spec pointer.

Subject: [PATCH 582/997] [PATCH] ppc64: Remove PTRRELOC() from msChunks code
The msChunks code was written to work on pSeries, but now it's only used on
iSeries. This means there's no need to do PTRRELOC anymore, so remove it all.
A few places were getting "extern reloc_offset()" from abs_addr.h, move it
into system.h instead.

Subject: [PATCH 583/997] [PATCH] ppc64: msChunks cleanups
Chunks are 256KB, so use constants for the size/shift/mask, rather than
getting them from the msChunks struct. The iSeries debugger (??) might still
need access to the values in the msChunks struct, so we keep them around
for now, but set them from the constant values.
Replace msChunks_entry typedef with regular u32.
Simplify msChunks_alloc() to manipulate klimit directly, rather than via
a parameter.
Move msChunks_alloc() and msChunks into iSeries_setup.c, as that's where
they're used.

physRpn_to_absRpn is a no-op on non-iSeries platforms, remove the two

There's only one caller on iSeries so fold the logic in there so we can get

Subject: [PATCH 587/997] [PATCH] ppc64: Remove redundant use of pointers in
lmb code
The lmb code is all written to use a pointer to an lmb struct. But it's always
the same lmb struct, called "lmb". So we take the address of lmb, call it
_lmb and then start using _lmb->foo everywhere, which is silly.
This patch removes the _lmb pointers and replaces them with direct references
to the one "lmb" struct. We do the same for some _mem and _rsv pointers which
point to lmb.memory and lmb.reserved respectively.
This patch looks quite busy, but it's basically just:
s/_lmb->/lmb./g
s/_mem->/lmb.memory./g
s/_rsv->/lmb.reserved./g
s/_rsv/&lmb.reserved/g
s/mem->/lmb.memory./g

Subject: [PATCH 588/997] [PATCH] ppc64: Remove redundant abs_to_phys() macro
abs_to_phys() is a macro that turns out to do nothing, and also has the
unfortunate property that it's not the inverse of phys_to_abs() on iSeries.
The following is for my benefit as much as everyone else.
With CONFIG_MSCHUNKS enabled, the lmb code is changed such that it keeps
a physbase variable for each lmb region. This is used to take the possibly
discontiguous lmb regions and present them as a contiguous address space
beginning from zero.
In this context each lmb region's base address is its "absolute" base
address, and its physbase is it's "physical" address (from Linux's point of
view). The abs_to_phys() macro does the mapping from "absolute" to "physical".
Note: This is not related to the iSeries mapping of physical to absolute
(ie. Hypervisor) addresses which is maintained with the msChunks structure.
And the msChunks structure is not controlled via CONFIG_MSCHUNKS.
Once upon a time you could compile for non-iSeries with CONFIG_MSCHUNKS
enabled. But these days CONFIG_MSCHUNKS depends on CONFIG_PPC_ISERIES, so
for non-iSeries code abs_to_phys() is a no-op.
On iSeries we always have one lmb region which spans from 0 to
systemcfg->physicalMemorySize (arch/ppc64/kernel/iSeries_setup.c line 383).
This region has a base (ie. absolute) address of 0, and a physbase address
of 0 (as calculated in lmb_analyze() (arch/ppc64/kernel/lmb.c line 144)).
On iSeries, abs_to_phys(aa) is defined as lmb_abs_to_phys(aa), which finds
the lmb region containing aa (and there's only one, ie. 0), and then does:
return lmb.memory.region[0].physbase + (aa - lmb.memory.region[0].base)
physbase == base == 0, so you're left with "return aa".
So remove abs_to_phys(), and lmb_abs_to_phys() which is the implementation
of abs_to_phys() for iSeries.

lmb_phys_mem_size() can always return lmb.memory.size, as long as it's called
after lmb_analyze(), which it is. There's no need to recalculate the size on
every call.
lmb_analyze() was calculating a few things we then threw away, so just don't
calculate them to start with.

Subject: [PATCH 592/997] [PATCH] ppc64: allow xmon=off
If both CONFIG_XMON and CONFIG_XMON_DEFAULT is enabled in the .config,
there is no way to disable xmon again. setup_system calls first xmon_init,
later parse_early_param. So a new 'xmon=off' cmdline option will do the right
thing.

Subject: [PATCH 593/997] [PATCH] ppc64: Move ppc64_enable_pmcs() logic into a
ppc_md function
This patch moves power4_enable_pmcs() to arch/ppc64/kernel/pmc.c.
I've tested it on P5 LPAR and P4. It does what it used to.

Subject: [PATCH 597/997] [PATCH] Dynamic hugepage addresses for ppc64
Paulus, I think this is now a reasonable candidate for the post-2.6.13
queue.
Relax address restrictions for hugepages on ppc64
Presently, 64-bit applications on ppc64 may only use hugepages in the
address region from 1-1.5T. Furthermore, if hugepages are enabled in
the kernel config, they may only use hugepages and never normal pages
in this area. This patch relaxes this restriction, allowing any
address to be used with hugepages, but with a 1TB granularity. That
is if you map a hugepage anywhere in the region 1TB-2TB, that entire
area will be reserved exclusively for hugepages for the remainder of
the process's lifetime. This works analagously to hugepages in 32-bit
applications, where hugepages can be mapped anywhere, but with 256MB
(mmu segment) granularity.
This patch applies on top of the four level pagetable patch
(http://patchwork.ozlabs.org/linuxppc64/patch?id=1936).

Subject: [PATCH 599/997] [PATCH] convert signal handling of NODEFER to act
like other Unix boxes.
It has been reported that the way Linux handles NODEFER for signals is
not consistent with the way other Unix boxes handle it. I've written a
program to test the behavior of how this flag affects signals and had
several reports from people who ran this on various Unix boxes,
confirming that Linux seems to be unique on the way this is handled.
The way NODEFER affects signals on other Unix boxes is as follows:
1) If NODEFER is set, other signals in sa_mask are still blocked.
2) If NODEFER is set and the signal is in sa_mask, then the signal is
still blocked. (Note: this is the behavior of all tested but Linux _and_
NetBSD 2.0 *).
The way NODEFER affects signals on Linux:
1) If NODEFER is set, other signals are _not_ blocked regardless of
sa_mask (Even NetBSD doesn't do this).
2) If NODEFER is set and the signal is in sa_mask, then the signal being
handled is not blocked.
The patch converts signal handling in all current Linux architectures to
the way most Unix boxes work.
Unix boxes that were tested: DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU
3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX.
* NetBSD was the only other Unix to behave like Linux on point #2. The
main concern was brought up by point #1 which even NetBSD isn't like
Linux. So with this patch, we leave NetBSD as the lonely one that
behaves differently here with #2.

Subject: [PATCH 601/997] [PATCH] mod_devicetable.h fixes
* ieee1394_device_id has kernel_ulong_t field after an odd number of
__u32 ones. Since mod_devicetable.h is included both from kernel and
from host build helper, we may be in trouble if we are building on
32bit host for 64bit target - userland sees unsigned long long,
kernel sees unsigned long and while their sizes match, alignments
might not. Fixed by forcing alignment. Fortunately, almost nobody
else needs that - the rest of such fields is naturally aligned as it
is.
* of_device_id has void * in it. Host userland helpers need
kernel_ulong_t instead, since their void * might have nothing to do
with the kernel one. Fixed in the same way it's done for similar
problems in pcmcia_device_id (ifdef __KERNEL__).
* pcmcia_device_id has the same problem as ieee1394_device_id. Fixed
the same way.

Subject: [PATCH 607/997] [SPARC64]: Revamp Spitfire error trap handling.
Current uncorrectable error handling was poor enough
that the processor could just loop taking the same
trap over and over again. Fix things up so that we
at least get a log message and perhaps even some register
state.
In the process, much consolidation became possible,
particularly with the correctable error handler.
Prefix assembler and C function names with "spitfire"
to indicate that these are for Ultra-I/II/IIi/IIe only.
More work is needed to make these routines robust and
featureful to the level of the Ultra-III error handlers.

Subject: [PATCH 610/997] [SPARC64]: Make debugging spinlocks usable again.
When the spinlock routines were moved out of line into
kernel/spinlock.c this made it so that the debugging
spinlocks record lock acquisition program counts in the
kernel/spinlock.c functions not in their callers.
This makes the debugging info kind of useless.
So record the correct caller's program counter and
now this feature is useful once more.

Subject: [PATCH 611/997] [SPARC64]: More fully work around Spitfire Errata 51.
It appears that a memory barrier soon after a mispredicted
branch, not just in the delay slot, can cause the hang
condition of this cpu errata.
So move them out-of-line, and explicitly put them into
a "branch always, predict taken" delay slot which should
fully kill this problem.

+ /* These are here in an effort to more fully work around
+ * Spitfire Errata #51. Essentially, if a memory barrier
+ * occurs soon after a mispredicted branch, the chip can stop
+ * executing instructions until a trap occurs. Therefore, if
+ * interrupts are disabled, the chip can hang forever.
+ *
+ * It used to be believed that the memory barrier had to be
+ * right in the delay slot, but a case has been traced
+ * recently wherein the memory barrier was one instruction
+ * after the branch delay slot and the chip still hung. The
+ * offending sequence was the following in sym_wakeup_done()
+ * of the sym53c8xx_2 driver:
+ *
+ * call sym_ccb_from_dsa, 0
+ * movge %icc, 0, %l0
+ * brz,pn %o0, .LL1303
+ * mov %o0, %l2
+ * membar #LoadLoad
+ *
+ * The branch has to be mispredicted for the bug to occur.
+ * Therefore, we put the memory barrier explicitly into a
+ * "branch always, predicted taken" delay slot to avoid the
+ * problem case.

From bdf82b59c5dcf04bbdbd1938eefca14dd9cb44d3 Mon Sep 17 00:00:00 2001
From: Deepak Saxena <dsaxena@plexity.net>

Subject: [PATCH 613/997] [ARM] 2836/1: Cleanup IXP4xx GPIO code
Patch from Deepak Saxena
This patch implements the set_irq_type() hooks for configuring GPIO
IRQ type and updates all the platforms to use it instead of the
gpio_line_config() function which is now used to configure input
vs. output on the pins.

Subject: [PATCH 618/997] [ARM] 2853/1: Make alloc_init_supersection() work
with 36-bit mappings
Patch from Deepak Saxena
Working on adding support for 36-bit static mappings for ARMv6 and
Intel's XSC3 core and noticed that alloc_init_supersection currently
increments the phys addr by 1MB on each of the 16 iterations and then
forces alignment to supersection size (16MB). This is really uneeded
b/c we have already forced the phys address to be 16MB aligned in
create_mapping(). Furthermore, this breaks 36-bit addressing b/c bits
[23:20] of the PMD contain bits [35:32] of the physical address and
the masking causes us to loose those bits thus ending up with an
incorrect virt -> phys translation. The other option is to have an
alloc_init_supersection36.
Tested on Intel IXP2350 CPU with 36-bit static I/O mappings.

Subject: [PATCH 620/997] [NETFILTER]: reduce netfilter sk_buff enlargement
As discussed at netconf'05, we're trying to save every bit in sk_buff.
The patch below makes sk_buff 8 bytes smaller. I did some basic
testing on my notebook and it seems to work.
The only real in-tree user of nfcache was IPVS, who only needs a
single bit. Unfortunately I couldn't find some other free bit in
sk_buff to stuff that bit into, so I introduced a separate field for
them. Maybe the IPVS guys can resolve that to further save space.
Initially I wanted to shrink pkt_type to three bits (PACKET_HOST and
alike are only 6 values defined), but unfortunately the bluetooth code
overloads pkt_type :(
The conntrack-event-api (out-of-tree) uses nfcache, but Rusty just
came up with a way how to do it without any skb fields, so it's safe
to remove it.
- remove all never-implemented 'nfcache' code
- don't have ipvs code abuse 'nfcache' field. currently get's their own
compile-conditional skb->ipvs_property field. IPVS maintainers can
decide to move this bit elswhere, but nfcache needs to die.
- remove skb->nfcache field to save 4 bytes
- move skb->nfctinfo into three unused bits to save further 4 bytes

From 8728b834b226ffcf2c94a58530090e292af2a7bf Mon Sep 17 00:00:00 2001
From: "David S. Miller" <davem@davemloft.net>
Date: Tue, 9 Aug 2005 19:25:21 -0700
Subject: [PATCH 621/997] [NET]: Kill skb->list
Remove the "list" member of struct sk_buff, as it is entirely
redundant. All SKB list removal callers know which list the
SKB is on, so storing this in sk_buff does nothing other than
taking up some space.
Two tricky bits were SCTP, which I took care of, and two ATM
drivers which Francois Romieu <romieu@fr.zoreil.com> fixed
up.

From: Harald Welte <laforge@netfilter.org>
Date: Tue, 9 Aug 2005 19:28:03 -0700
Subject: [PATCH 623/997] [NETFILTER]: connection tracking event notifiers
This adds a notifier chain based event mechanism for ip_conntrack state
changes. As opposed to the previous implementations in patch-o-matic, we
do no longer need a field in the skb to achieve this.
Thanks to the valuable input from Patrick McHardy and Rusty on the idea
of a per_cpu implementation.

From f9e815b376dc19e6afc551cd755ac64e9e42d81f Mon Sep 17 00:00:00 2001
From: Harald Welte <laforge@netfilter.org>
Date: Tue, 9 Aug 2005 19:30:24 -0700
Subject: [PATCH 624/997] [NETFITLER]: Add nfnetlink layer.
Introduce "nfnetlink" (netfilter netlink) layer. This layer is used as
transport layer for all userspace communication of the new upcoming
netfilter subsystems, such as ctnetlink, nfnetlink_queue and some day even
the mythical pkttables ;)

Subject: [PATCH 626/997] [NET]: Remove HIPPI private from skbuff.h
This removes the private element from skbuff, that is only used by
HIPPI. Instead it uses skb->cb[] to hold the additional data that is
needed in the output path from hard_header to device driver.
PS: The only qdisc that might potentially corrupt this cb[] is if
netem was used over HIPPI. I will take care of that by fixing netem
to use skb->stamp. I don't expect many users of netem over HIPPI

Subject: [PATCH 627/997] [NETFILTER]: Add ctnetlink subsystem
Add ctnetlink subsystem for userspace-access to ip_conntrack table.
This allows reading and updating of existing entries, as well as
creating new ones (and new expect's) via nfnetlink.
Please note the 'strange' byte order: nfattr (tag+length) are in host
byte order, while the payload is always guaranteed to be in network
byte order. This allows a simple userspace process to encapsulate netlink
messages into arch-independent udp packets by just processing/swapping the
headers and not knowing anything about the actual payload.

Subject: [PATCH 630/997] [NET]: Kill skb->real_dev
Bonding just wants the device before the skb_bond()
decapsulation occurs, so simply pass that original
device into packet_type->func() as an argument.
It remains to be seen whether we can use this same
exact thing to get rid of skb->input_dev as well.

Subject: [PATCH 631/997] [IPV4]: possible cleanups
This patch contains the following possible cleanups:
- make needlessly global code static
- #if 0 the following unused global function:
- xfrm4_state.c: xfrm4_state_fini
- remove the following unneeded EXPORT_SYMBOL's:
- ip_output.c: ip_finish_output
- ip_output.c: sysctl_ip_default_ttl
- fib_frontend.c: ip_dev_find
- inetpeer.c: inet_peer_idlock
- ip_options.c: ip_options_compile
- ip_options.c: ip_options_undo
- net/core/request_sock.c: sysctl_max_syn_backlog

From: "David S. Miller" <davem@davemloft.net>
Date: Tue, 9 Aug 2005 19:36:29 -0700
Subject: [PATCH 632/997] [NET]: Remove explicit initializations of
skb->input_dev
Instead, set it in one place, namely the beginning of
netif_receive_skb().
Based upon suggestions from Jamal Hadi Salim.

Subject: [PATCH 634/997] [NETFILTER]: Rename skb_ip_make_writable() to
skb_make_writable()
There is nothing IPv4-specific in it. In fact, it was already used by
IPv6, too... Upcoming nfnetlink_queue code will use it for any kind
of packet.

From 4fdb3bb723db469717c6d38fda667d8b0fa86ebd Mon Sep 17 00:00:00 2001
From: Harald Welte <laforge@netfilter.org>
Date: Tue, 9 Aug 2005 19:40:55 -0700
Subject: [PATCH 636/997] [NETLINK]: Add properly module refcounting for kernel
netlink sockets.
- Remove bogus code for compiling netlink as module
- Add module refcounting support for modules implementing a netlink
protocol
- Add support for autoloading modules that implement a netlink protocol
as soon as someone opens a socket for that protocol
Signed-off-by: Harald Welte <laforge@netfilter.org>

From 2cc7d5730957c4a3f3659d17d2ba5e06d5581c1f Mon Sep 17 00:00:00 2001
From: Harald Welte <laforge@netfilter.org>
Date: Tue, 9 Aug 2005 19:42:34 -0700
Subject: [PATCH 637/997] [NETFILTER]: Move reroute-after-queue code up to the
nf_queue layer.
The rerouting functionality is required by the core, therefore it has
to be implemented by the core and not in individual queue handlers.
Signed-off-by: Harald Welte <laforge@netfilter.org>

From: Harald Welte <laforge@netfilter.org>
Date: Tue, 9 Aug 2005 19:43:44 -0700
Subject: [PATCH 638/997] [NETFILTER]: Core changes required by upcoming
nfnetlink_queue code
- split netfiler verdict in 16bit verdict and 16bit queue number
- add 'queuenum' argument to nf_queue_outfn_t and its users ip[6]_queue
- move NFNL_SUBSYS_ definitions from enum to #define
- introduce autoloading for nfnetlink subsystem modules
- add MODULE_ALIAS_NFNL_SUBSYS macro
- add nf_unregister_queue_handlers() to register all handlers for a given
nf_queue_outfn_t
- add more verbose DEBUGP macro definition to nfnetlink.c
- make nfnetlink_subsys_register fail if subsys already exists
- add some more comments and debug statements to nfnetlink.c

Subject: [PATCH 640/997] [IPV6]: Check interface bindings on IPv6 raw socket
reception
Take account of whether a socket is bound to a particular device when
selecting an IPv6 raw socket to receive a packet. Also perform this
check when receiving IPv6 packets with router alert options.

From tcp_v4_setup_caps, that always is preceded by a call to

From 32519f11d38ea8f4f60896763bacec7db1760f9c Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
Date: Tue, 9 Aug 2005 19:50:02 -0700
Subject: [PATCH 645/997] [INET]: Introduce inet_sk_rebuild_header
From tcp_v4_rebuild_header, that already was pretty generic, I only
needed to use sk->sk_protocol instead of the hardcoded IPPROTO_TCP and
establish the requirement that INET transport layer protocols that
want to use this function map TCP_SYN_SENT to its equivalent state.

From 608c8e4f7b6e61cc783283e9dff8a465a5ad59bb Mon Sep 17 00:00:00 2001
From: Harald Welte <laforge@netfilter.org>
Date: Tue, 9 Aug 2005 19:58:27 -0700
Subject: [PATCH 647/997] [NETFILTER]: Extend netfilter logging API
This patch is in preparation to nfnetlink_log:
- loggers now have to register struct nf_logger instead of nf_logfn
- nf_log_unregister() replaced by nf_log_unregister_pf() and
nf_log_unregister_logger()
- add comment to ip[6]t_LOG.h to assure nobody redefines flags
- add /proc/net/netfilter/nf_log to tell user which logger is currently
registered for which address family
- if user has configured logging, but no logging backend (logger) is
available, always spit a message to syslog, not just the first time.
- split ip[6]t_LOG.c into two parts:
Backend: Always try to register as logger for the respective address family
Frontend: Always log via nf_log_packet() API
- modify all users of nf_log_packet() to accomodate additional argument

From 0597f2680d666a3bcf101ac0c771ba7e50016bbd Mon Sep 17 00:00:00 2001
From: Harald Welte <laforge@netfilter.org>
Date: Tue, 9 Aug 2005 19:58:39 -0700
Subject: [PATCH 648/997] [NETFILTER]: Add new "nfnetlink_log" userspace packet
logging facility
This is a generic (layer3 independent) version of what ipt_ULOG is already
doing for IPv4 today. ipt_ULOG, ebt_ulog and finally also ip[6]t_LOG will
be deprecated by this mechanism in the long term.

that will expose the already generic TCP hash table routines.
The few changes noticed when calling gcc -S before/after on a pentium4 were of
this type:

Subject: [PATCH 650/997] [INET]: Just rename the TCP hashtable
functions/structs to inet_
This is to break down the complexity of the series of patches,
making it very clear that this one just does:
1. renames tcp_ prefixed hashtable functions and data structures that
were already mostly generic to inet_ to share it with DCCP and
other INET transport protocols.
2. Removes not used functions (__tb_head & tb_head)
3. Removes some leftover prototypes in the headers (tcp_bucket_unlock &
tcp_v4_build_header)
Next changesets will move tcp_sk(sk)->bind_hash to inet_sock so that we can
make functions such as tcp_inherit_port, __tcp_inherit_port, tcp_v4_get_port,
__tcp_put_port, generic and get others like tcp_destroy_sock closer to generic
(tcp_orphan_count will go to sk->sk_prot to allow this).
Eventually most of these functions will be used passing the transport protocol
inet_hashinfo structure.

From a55ebcc4c4532107ad9eee1c9bb698ab5f12c00f Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
Date: Tue, 9 Aug 2005 20:01:14 -0700
Subject: [PATCH 652/997] [INET]: Move bind_hash from tcp_sk to inet_sk
This should really be in a inet_connection_sock, but I'm leaving it
for a later optimization, when some more fields common to INET
transport protocols now in tcp_sk or inet_sk will be chunked out into
inet_connection_sock, for now its better to concentrate on getting the
changes in the core merged to leave the DCCP tree with only DCCP
specific code.
Next changesets will take advantage of this move to generalise things
like tcp_bind_hash, tcp_put_port, tcp_inherit_port, making the later
receive a inet_hashinfo parameter, and even __tcp_tw_hashdance, etc in
the future, when tcp_tw_bucket gets transformed into the struct
timewait_sock hierarchy.
tcp_destroy_sock also is eligible as soon as tcp_orphan_count gets
moved to sk_prot.
A cascade of incremental changes will ultimately make the tcp_lookup
functions be fully generic.

Subject: [PATCH 653/997] [NETFILTER]: Fix multiple problems with the conntrack
event cache
refcnt underflow: the reference count is decremented when a conntrack
entry is removed from the hash but it is not incremented when entering
new entries.
missing protection of process context against softirq context: all
cache operations need to locally disable softirqs to avoid races.
Additionally the event cache can't be initialized when a packet
enteres the conntrack code but needs to be initialized whenever we
cache an event and the stored conntrack entry doesn't match the
current one.
incorrect flushing of the event cache in ip_ct_iterate_cleanup:
without real locking we can't flush the cache for different CPUs
without incurring races. The cache for different CPUs can only be
flushed when no packets are going through the
code. ip_ct_iterate_cleanup doesn't need to drop all references, so
flushing is moved to the cleanup path.

nfattr_parse_nested() calls nfattr_parse() which in turn does a memset

calling it.

Subject: [PATCH 657/997] [NETFILTER]: attribute count is an attribute of
message type, not subsytem
Prior to this patch, every nfnetlink subsystem had to specify it's
attribute count. However, in reality the attribute count depends on
the message type within the subsystem, not the subsystem itself. This
patch moves 'attr_count' from 'struct nfnetlink_subsys' into
nfnl_callback to fix this.

Subject: [PATCH 659/997] [NETFILTER]: don't use nested attributes for
conntrack_expect
We used to use nested nfattr structures for ip_conntrack_expect. This is
bogus, since ip_conntrack and ip_conntrack_expect are communicated in
different netlink message types. both should be encoded at the top level
attributes, no extra nesting required. This patch addresses the issue.

The following sequence is displayed during events dumping of an ICMP

This happens because the event IPCT_DESTROY is delivered in
death_by_timeout(), that is called from the icmp protocol helper
(ct->timeout.function) once we see the reply.
To fix this, we move this event to destroy_conntrack().

Subject: [PATCH 663/997] [NETFILTER]: fix list traversal order in ctnetlink
Currently conntracks are inserted after the head. That means that
conntracks are sorted from the biggest to the smallest id. This happens
because we use list_prepend (list_add) instead list_add_tail. This can
result in problems during the list iteration.
list_for_each(i, &ip_conntrack_hash[cb->args[0]]) {
h = (struct ip_conntrack_tuple_hash *) i;
if (DIRECTION(h) != IP_CT_DIR_ORIGINAL)
continue;
ct = tuplehash_to_ctrack(h);
if (ct->id <= *id)
continue;
In that case just the first conntrack in the bucket will be dumped. To
fix this, we iterate the list from the tail to the head via

From 6e04e02165a7209a71db553b7bc48d68421e5ebf Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
Date: Tue, 9 Aug 2005 20:07:35 -0700
Subject: [PATCH 665/997] [INET]: Move tcp_port_rover to inet_hashinfo
Also expose all of the tcp_hashinfo members, i.e. killing those
tcp_ehash, etc macros, this will more clearly expose already generic
functions and some that need just a bit of work to become generic, as
we'll see in the upcoming changesets.

From c752f0739f09b803aed191c4765a3b6650a08653 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
Date: Tue, 9 Aug 2005 20:08:28 -0700
Subject: [PATCH 667/997] [TCP]: Move the tcp sock states to net/tcp_states.h
Lots of places just needs the states, not even linux/tcp.h, where this
enum was, needs it.
This speeds up development of the refactorings as less sources are
rebuilt when things get moved from net/tcp.h.

Subject: [PATCH 668/997] [INET]: Generalise tcp_v4_hash & tcp_unhash
It really just makes the existing code be a helper function that
tcp_v4_hash and tcp_unhash uses, specifying the right inet_hashinfo,
tcp_hashinfo.
One thing I'll investigate at some point is to have the inet_hashinfo
pointer in sk_prot, so that we get all the hashtable information from
the sk pointer, this can lead to some extra indirections that may well
hurt performance/code size, we'll see. Ultimate idea would be that
sk_prot would provide _all_ the information about a protocol
implementation.

Subject: [PATCH 670/997] [INET]: Generalise tcp_tw_bucket, aka TIME_WAIT
sockets
This paves the way to generalise the rest of the sock ID lookup
routines and saves some bytes in TCPv4 TIME_WAIT sockets on distro
kernels (where IPv6 is always built as a module):
[root@qemu ~]# grep tw_sock /proc/slabinfo
tw_sock_TCPv6 0 0 128 31 1
tw_sock_TCP 0 0 96 41 1
[root@qemu ~]#
Now if a protocol wants to use the TIME_WAIT generic infrastructure it
only has to set the sk_prot->twsk_obj_size field with the size of its
inet_timewait_sock derived sock and proto_register will create
sk_prot->twsk_slab, for now its only for INET sockets, but we can
introduce timewait_sock later if some non INET transport protocolo
wants to use this stuff.
Next changesets will take advantage of this new infrastructure to
generalise even more TCP code.

From e48c414ee61f4ac8d5cff2973e66a7cbc8a93aa5 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
Date: Tue, 9 Aug 2005 20:09:46 -0700
Subject: [PATCH 671/997] [INET]: Generalise the TCP sock ID lookup routines
And also some TIME_WAIT functions.
[acme@toy net-2.6.14]$ grep built-in /tmp/before.size /tmp/after.size
/tmp/before.size: 282955 13122 9312 305389 4a8ed net/ipv4/built-in.o
/tmp/after.size: 281566 13122 9312 304000 4a380 net/ipv4/built-in.o
[acme@toy net-2.6.14]$
I kept them still inlined, will uninline at some point to see what
would be the performance difference.

Subject: [PATCH 672/997] [INET_TWSK]: Introduce inet_twsk_alloc
With the parts of tcp_time_wait that are not TCP specific, tcp_time_wait uses
it and so will dccp_time_wait.

Subject: [PATCH 674/997] [NET]: Introduce inet_connection_sock
This creates struct inet_connection_sock, moving members out of struct
tcp_sock that are shareable with other INET connection oriented
protocols, such as DCCP, that in my private tree already uses most of
these members.
The functions that operate on these members were renamed, using a
inet_csk_ prefix while not being moved yet to a new file, so as to
ease the review of these changes.

From 3f421baa4720b708022f8bcc52a61e5cd6f10bf8 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
Date: Tue, 9 Aug 2005 20:11:08 -0700
Subject: [PATCH 675/997] [NET]: Just move the inet_connection_sock function
from tcp sources
Completing the previous changeset, this also generalises tcp_v4_synq_add,
renaming it to inet_csk_reqsk_queue_hash_add, already geing used in the
DCCP tree, which I plan to merge RSN.

Subject: [PATCH 677/997] [ICSK]: Generalise tcp_listen_{start,stop}
This also moved inet_iif from tcp to inet_hashtables.h, as it is
needed by the inet_lookup callers, perhaps this needs a bit of
polishing, but for now seems fine.

Subject: [PATCH 678/997] [ICSK]: Introduce reqsk_queue_prune from code in
tcp_synack_timer
With this we're very close to getting all of the current TCP
refactorings in my dccp-2.6 tree merged, next changeset will export
some functions needed by the current DCCP code and then dccp-2.6.git
will be born!

Subject: [PATCH 681/997] [DCCP]: Initial implementation
Development to this point was done on a subversion repository at:
http://oops.ghostprotocols.net:81/cgi-bin/viewcvs.cgi/dccp-2.6/
This repository will be kept at this site for the foreseable future,
so that interested parties can see the history of this code,
attributions, etc.
If I ever decide to take this offline I'll provide the full history at
some other suitable place.

+ Datagram Congestion Control Protocol
+
+ From draft-ietf-dccp-spec-11 <http://www.icir.org/kohler/dcp/draft-ietf-dccp-spec-11.txt>.
+
+ The Datagram Congestion Control Protocol (DCCP) is a transport
+ protocol that implements bidirectional, unicast connections of
+ congestion-controlled, unreliable datagrams. It should be suitable
+ for use by applications such as streaming media, Internet telephony,
+ and on-line games
+
+ To compile this protocol support as a module, choose M here: the
+ module will be called dccp.
+
+ If in doubt, say N.

+ ---help---
+ CCID 3 denotes TCP-Friendly Rate Control (TFRC), an equation-based
+ rate-controlled congestion control mechanism. TFRC is designed to
+ be reasonably fair when competing for bandwidth with TCP-like flows,
+ where a flow is "reasonably fair" if its sending rate is generally
+ within a factor of two of the sending rate of a TCP flow under the
+ same conditions. However, TFRC has a much lower variation of
+ throughput over time compared with TCP, which makes CCID 3 more
+ suitable than CCID 2 for applications such streaming media where a
+ relatively smooth sending rate is of importance.
+
+ CCID 3 is further described in [CCID 3 PROFILE]. The TFRC
+ congestion control algorithms were initially described in RFC 3448.
+
+ This text was extracted from draft-ietf-dccp-spec-11.txt.
+
+ If in doubt, say M.

+/* Calculate the send rate as per section 3.1 of RFC3448
+
+Returns send rate in bytes per second
+
+Integer maths and lookups are used as not allowed floating point in kernel
+
+The function for Xcalc as per section 3.1 of RFC3448 is:
+
+X = s
+ -------------------------------------------------------------
+ R*sqrt(2*b*p/3) + (t_RTO * (3*sqrt(3*b*p/8) * p * (1+32*p^2)))
+
+where
+X is the trasmit rate in bytes/second
+s is the packet size in bytes
+R is the round trip time in seconds
+p is the loss event rate, between 0 and 1.0, of the number of loss events
+ as a fraction of the number of packets transmitted
+t_RTO is the TCP retransmission timeout value in seconds
+b is the number of packets acknowledged by a single TCP acknowledgement
+
+we can assume that b = 1 and t_RTO is 4 * R. With this the equation becomes:
+
+X = s
+ -----------------------------------------------------------------------
+ R * sqrt(2 * p / 3) + (12 * R * (sqrt(3 * p / 8) * p * (1 + 32 * p^2)))
+
+
+which we can break down into:
+
+X = s
+ --------
+ R * f(p)
+
+where f(p) = sqrt(2 * p / 3) + (12 * sqrt(3 * p / 8) * p * (1 + 32 * p * p))
+
+Function parameters:
+s - bytes
+R - RTT in usecs
+p - loss rate (decimal fraction multiplied by 1,000,000)
+
+Returns Xcalc in bytes per second

From a019d6fe2b9da68ea4ba6cf3c4e86fc1dbf554c3 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
Date: Tue, 9 Aug 2005 20:15:09 -0700
Subject: [PATCH 682/997] [ICSK]: Move generalised functions from tcp to
inet_connection_sock
This also improves reqsk_queue_prune and renames it to
inet_csk_reqsk_queue_prune, as it deals with both inet_connection_sock
and inet_request_sock objects, not just with request_sock ones thus
belonging to inet_request_sock.

Subject: [PATCH 686/997] [TG3]: Add basic register access function pointers
This patch adds the basic function pointers to do register accesses in
the fast path. This was suggested by David Miller. The idea is that
various register access methods for different hardware errata can easily
be implemented with these function pointers and performance will not be
degraded on chips that use normal register access methods.
The various register read write macros (e.g. tw32, tr32, tw32_mailbox)
are redefined to call the function pointers.

Subject: [PATCH 689/997] [TG3]: Add indirect register method for 5703 behind
ICH
This patch adds the new workaround for 5703 A1/A2 if it is behind
certain ICH bridges. The workaround disables memory and uses config.
cycles only to access all registers. The 5702/03 chips can mistakenly
decode the special cycles from the ICH chipsets as memory write cycles,
causing corruption of register and memory space. Only certain ICH
bridges will drive special cycles with non-zero data during the address
phase which can fall within the 5703's address range. This is not an ICH
bug as the PCI spec allows non-zero address during special cycles.
However, only these ICH bridges are known to drive non-zero addresses
during special cycles.
The indirect_lock is also changed to spin_lock_irqsave from spin_lock_bh
because it is used in irq handler when using the indirect method to

Subject: [PATCH 690/997] [TG3]: Eliminate one register write in
tg3_restart_ints()
The register write to register 0x68 to restart interrupts is unnecessary
as the interrupt wasn't masked in that register by the irq handler. This
will save one register write in the fast path.

Subject: [PATCH 691/997] [TG3]: Fix bug in setting a tg3_flag
Found a bug while reviewing the patches the second time.
The TG3_FLAG_TXD_MBOX_HWBUG flag is set after the register access
methods have been determined. This patch fixes it by moving it up before
the various access methods are assigned.

Subject: [PATCH 693/997] [NETFILTER]: move conntrack helper buffers from BSS
to kmalloc()ed memory
According to DaveM, it is preferrable to have large data structures be
allocated dynamically from the module init() function rather than
putting them as static global variables into BSS.
This patch moves the conntrack helper packet buffers into dynamically
allocated memory.

Subject: [PATCH 696/997] [NETFILTER]: ip{6}_queue: prevent unregistration race
with nfnetlink_queue
Since nfnetlink_queue can override ip{6}_queue as queue handlers, we
can no longer blindly unregister whoever is registered for PF_INET[6],
but only unregister ourselves.

Subject: [PATCH 697/997] [NETFILTER]: split net/core/netfilter.c into
net/netfilter/*.c
This patch doesn't introduce any code changes, but merely splits the
core netfilter code into four separate files. It also moves it from
it's old location in net/core/ to the recently-created net/netfilter/
directory.

From fbcd923c3e0c8ec9e4ed64f5a4e5766807b32729 Mon Sep 17 00:00:00 2001
From: Harald Welte <laforge@netfilter.org>
Date: Tue, 9 Aug 2005 20:22:10 -0700
Subject: [PATCH 698/997] [NETFILTER]: add correct bridging support to
nfnetlink_{queue,log}
This patch adds support for passing the real 'physical' device ifindex
down to userspace via nfnetlink_log and nfnetlink_queue.
This feature basically obsoletes net/bridge/netfilter/ebt_ulog.c, and
it is likely ebt_ulog.c will die with one of the next couple of
patches.

Subject: [PATCH 699/997] [NETFILTER]: add /proc/net/netfilter interface to
nf_queue
This patch adds a /proc/net/netfilter/nf_queue file, similar to the
recently-added /proc/net/netfilter/nf_log. It indicates which queue
handler is registered to which protocol family. This is useful since
there are now multiple queue handlers in the treee (ip[6]_queue,
nfnetlink_queue).

EEXIST: the exact same handler was already registered, no registration
required
EBUSY: somebody else is registered, registration unsuccessful.

Subject: [PATCH 702/997] [NETFILTER]: return ENOMEM when ip_conntrack_alloc()
fails.
This patch fixes the bug which doesn't return ERR_PTR(-ENOMEM) if it
failed to allocate memory space from slab cache. This bug leads to
erroneously not dropped packets under stress, and wrong statistic
counters ('invalid' is incremented instead of 'drop'). It was
introduced during the ctnetlink merge in the net-2.6.14 tree, so no
stable or mainline releases affected.

Subject: [PATCH 703/997] [IPV4]: FIB Trie cleanups.
Below is a patch that cleans up some of this, supposedly without
changing any behaviour:
* Whitespace cleanups
* Introduce DBG()
* BUG_ON() instead of if () { BUG(); }
* Remove some of the deep nesting to make the code flow more
comprehensible
* Some mask operations were simplified

Subject: [PATCH 706/997] [DCCP]: make <linux/dccp.h> include-able from
userspace
The protocol header files in <linux/foo.h> are usually structured in a
way to be included by userspace code. The top section consists of
general protocol structure definitions, typedefs, enums - followed by
an #ifdef __KERNEL__ section.
Currently <linux/dccp.h> doesn't follow that convention and can
therefore not be used from userspace. However, for example iptables'
libipt_dccp.c actually needs various definitions from there.

Subject: [PATCH 711/997] [Bluetooth]: Workaround for inquiry results with RSSI
and page scan mode
This patch implements a workaround for buggy Bluetooth 1.2 devices from
Silicon Wave. Their inquiry results with RSSI contain the page scan mode
field. This field was removed in the final Bluetooth 1.2 specification.

Subject: [PATCH 716/997] [Bluetooth]: Move packet type into the SKB control
buffer
This patch moves the usage of packet type into the SKB control
buffer. After this patch it is now possible to shrink the sk_buff
structure and redefine its pkt_type.

From 27258ee54f8cd4a43d09319aa5448145afc2cb8d Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@mandriva.com>
Date: Tue, 9 Aug 2005 20:30:56 -0700
Subject: [PATCH 717/997] [DCCP]: Introduce dccp_write_xmit from code in
dccp_sendmsg
This way it gets closer to the TCP flow, where congestion window
checks are done, it seems we can map ccid_hc_tx_send_packet in
dccp_write_xmit to tcp_snd_wnd_test in tcp_write_xmit, a CCID2
decision should just fit in here as well...

Subject: [PATCH 718/997] [DCCP]: Initialize icsk_rto in dccp_v4_init_sock
Fixes nasty bug related to the retransmit timer (yeah, DCCP does
retransmits) firing too early.

Subject: [PATCH 719/997] [TIMEWAIT]: Introduce inet_timewait_death_row
That groups all of the tables and variables associated to the TCP timewait
schedulling/recycling/killing code, that now can be isolated from the TCP
specific code and used by other transport protocols, such as DCCP.
Next changeset will move this code to net/ipv4/inet_timewait_sock.c

From: Arnaldo Carvalho de Melo <acme@mandriva.com>
Date: Tue, 9 Aug 2005 20:45:03 -0700
Subject: [PATCH 720/997] [TIMEWAIT]: Move inet_timewait_death_row routines to
net/ipv4/inet_timewait_sock.c
Also export the ones that will be used in the next changeset, when
DCCP uses this infrastructure.

Subject: [PATCH 721/997] [DCCP]: Finish the TIMEWAIT minisock support
Using most of the infrastructure TCP uses, with a dccp_death_row,
etc. As per my current interpretation of the draft what we have with
this changeset seems to be all we need (or very close to it 8)).

From 6687e988d9aeaccad6774e6a8304f681f3ec0a03 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@mandriva.com>
Date: Wed, 10 Aug 2005 04:03:31 -0300
Subject: [PATCH 723/997] [ICSK]: Move TCP congestion avoidance members to icsk
This changeset basically moves tcp_sk()->{ca_ops,ca_state,etc} to inet_csk(),
minimal renaming/moving done in this changeset to ease review.
Most of it is just changes of struct tcp_sock * to struct sock * parameters.
With this we move to a state closer to two interesting goals:
1. Generalisation of net/ipv4/tcp_diag.c, becoming inet_diag.c, being used
for any INET transport protocol that has struct inet_hashinfo and are
derived from struct inet_connection_sock. Keeps the userspace API, that will
just not display DCCP sockets, while newer versions of tools can support
DCCP.
2. INET generic transport pluggable Congestion Avoidance infrastructure, using
the current TCP CA infrastructure with DCCP.

Subject: [PATCH 724/997] [TCPDIAG]: Implement cheapest way of supporting
DCCPDIAG_GETSOCK
With ugly ifdefs, etc, but this actually:
1. keeps the existing ABI, i.e. no need to recompile the iproute2
utilities if not interested in DCCP.
2. Provides all the tcp_diag functionality in DCCP, with just a
small patch that makes iproute2 support DCCP.
Of course I'll get this cleaned-up in time, but for now I think its
OK to be this way to quickly get this functionality.
iproute2-ss050808 patch at:

Subject: [PATCH 725/997] [CCID3]: Separate most of the packet history code
This also changes the list_for_each_entry_safe_continue behaviour to match its
kerneldoc comment, that is, to start after the pos passed.
Also adds several helper functions from previously open coded fragments, making
the code more clear.

Subject: [PATCH 727/997] [NET]: Make use of ->private_data in sockfd_lookup
Please consider the patch below which makes use of file->private_data to
store the pointer to the socket, which avoids touching several unused
cachelines in the dentry and inode in sockfd_lookup.

Subject: [PATCH 728/997] [BNX2]: Possible sparse fixes, take two
This patch contains the following possible cleanups/fixes:
- use C99 struct initializers
- make a few arrays and structs static
- remove a few uses of literal 0 as NULL pointer
- use convenience function instead of cast+dereference in bnx2_ioctl()
- remove superfluous casts to u8 * in calls to readl/writel

From 5324a040ccc708998e61ea93e669b81312f0ae11 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@mandriva.com>
Date: Fri, 12 Aug 2005 09:26:18 -0300
Subject: [PATCH 735/997] [INET6_HASHTABLES]: Move inet6_lookup functions to
net/ipv6/inet6_hashtables.c
Doing this we allow tcp_diag to support IPV6 even if tcp_diag is compiled
statically and IPV6 is compiled as a module, removing the previous restriction
while not building any IPV6 code if it is not selected.
Now to work on the tcpdiag_register infrastructure and then to rename the whole
thing to inetdiag, reflecting its by then completely generic nature.

From 4f5736c4c7cf6f9bd8db82b712cfdd51c87e06b9 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@mandriva.com>
Date: Fri, 12 Aug 2005 09:27:49 -0300
Subject: [PATCH 736/997] [TCPDIAG]: Introduce inet_diag_{register,unregister}
Next changeset will rename tcp_diag to inet_diag and move the tcp_diag code out
of it and into a new tcp_diag.c, similar to the net/dccp/diag.c introduced in
this changeset, completing the transition to a generic inet_diag
infrastructure.

Date: Fri, 12 Aug 2005 12:51:49 -0300
Subject: [PATCH 737/997] [TCPDIAG]: Just rename everything to inet_diag
Next changeset will rename tcp_diag.[ch] to inet_diag.[ch].
I'm taking this longer route so as to easy review, making clear the changes
made all along the way.

Subject: [PATCH 739/997] [INET_DIAG]: Move the tcp_diag interface to the
proper place
With this the previous setup is back, i.e. tcp_diag can be built as a module,
as dccp_diag and both share the infrastructure available in inet_diag.
If one selects CONFIG_INET_DIAG as module CONFIG_INET_TCP_DIAG will also be
built as a module, as will CONFIG_INET_DCCP_DIAG, if CONFIG_IP_DCCP was
selected static or as a module, if CONFIG_INET_DIAG is y, being statically
linked CONFIG_INET_TCP_DIAG will follow suit and CONFIG_INET_DCCP_DIAG will be
built in the same manner as CONFIG_IP_DCCP.
Now to aim at UDP, converting it to use inet_hashinfo, so that we can use
iproute2 for UDP sockets as well.
Ah, just to show an example of this new infrastructure working for DCCP :-)

Subject: [PATCH 740/997] [NETFILTER]: introduce and use aligned_u64 data type
As proposed by Andi Kleen, this is required esp. for x86_64 architecture,
where 64bit code needs 8byte aligned 64bit data types, but 32bit userspace
apps will only align to 4bytes.

Date: Sat, 13 Aug 2005 13:56:26 -0700
Subject: [PATCH 741/997] [NETFILTER]: Add new iptables "connbytes" match
This patch ads a new "connbytes" match that utilizes the CONFIG_NF_CT_ACCT
per-connection byte and packet counters. Using it you can do things like
packet classification on average packet size within a connection.

Subject: [PATCH 760/997] [NETLINK]: Fix module refcounting problems
Use-after-free: the struct proto_ops containing the module pointer
is freed when a socket with pid=0 is released, which besides for kernel
sockets is true for all unbound sockets.
Module refcount leak: when the kernel socket is closed before all user
sockets have been closed the proto_ops struct for this family is
replaced by the generic one and the module refcount can't be dropped.
The second problem can't be solved cleanly using module refcounting in the
generic socket code, so this patch adds explicit refcounting to
netlink_create/netlink_release.

Subject: [PATCH 761/997] [NETLINK]: Use group numbers instead of bitmasks
internally
Using the group number allows increasing the number of groups without
beeing limited by the size of the bitmask. It introduces one limitation
for netlink users: messages can't be broadcasted to multiple groups anymore,
however this feature was never used inside the kernel.

From ab33a1711cf60bfb562b1ab89ac9f23d1425e8b1 Mon Sep 17 00:00:00 2001
From: Patrick McHardy <kaber@trash.net>
Date: Sun, 14 Aug 2005 19:31:36 -0700
Subject: [PATCH 763/997] [NETLINK]: Return -EPROTONOSUPPORT in
netlink_create() if no kernel socket is registered
This is necessary for dynamic number of netlink groups to make sure we know
the number of possible groups before bind() is called. With this change pure
userspace communication using unused netlink protocols becomes impossible.

Subject: [PATCH 765/997] [NETLINK]: Add set/getsockopt options to support more
than 32 groups
NETLINK_ADD_MEMBERSHIP/NETLINK_DROP_MEMBERSHIP are used to join/leave
groups, NETLINK_PKTINFO is used to enable nl_pktinfo control messages
for received packets to get the extended destination group number.

Subject: [PATCH 773/997] [IRDA]: Possible cleanups.
This patch contains the following possible cleanups:
- make the following needlessly global function static:
- irnet/irnet_ppp.c: irnet_init
- remove the following unneeded EXPORT_SYMBOL's:
- irlmp.c: sysctl_discovery_timeout
- irlmp.c: irlmp_reasons
- irlmp.c: irlmp_dup
- irqueue.c: hashbin_find_next

From d179cd12928443f3ec29cfbc3567439644bd0afc Mon Sep 17 00:00:00 2001

Subject: [PATCH 776/997] [NET]: Implement SKB fast cloning.
Protocols that make extensive use of SKB cloning,
for example TCP, eat at least 2 allocations per
packet sent as a result.
To cut the kmalloc() count in half, we implement
a pre-allocation scheme wherein we allocate
2 sk_buff objects in advance, then use a simple
reference count to free up the memory at the
correct time.
Based upon an initial patch by Thomas Graf and
suggestions from Herbert Xu.

Subject: [PATCH 781/997] [DCCP]: Fix the timestamp options
This changes timestamp, timestamp echo, and elapsed time to use units of 10
usecs as per DCCP spec. This has been tested to verify that times are correct.
Also fixed up length and used hton/ntoh more.
Still to add in later patches:
- actually use elapsed time to adjust RTT
(commented out as was prior to this patch)
- send options at times more closely following the spec
(content is now correct)

So that we retransmit CLOSE/CLOSEREQ packets till they elicit an

Most of the machinery uses TCP approaches, this code has to be
polished & audited, but this is better than we had before.

Subject: [PATCH 806/997] [DCCP]: Introduce dccp_get_info
And also hc_tx and hc_rx get_info functions for the CCIDs to fill in
information that is specific to them.
For now reusing struct tcp_info, later I'll try to figure out a better
solution, for now its really nice to get this kind of info:
[root@qemu ~]# ./ss -danemi
State Recv-Q Send-Q Local Addr:Port Peer Addr:Port
LISTEN 0 0 *:5001 *:* ino:628 sk:c1340040
mem:(r0,w0,f0,t0) cwnd:0 ssthresh:0
ESTAB 0 0 172.20.0.2:5001 172.20.0.1:32785 ino:629 sk:c13409a0
mem:(r0,w0,f0,t0) ts rto:1000 rtt:0.004/0 cwnd:0 ssthresh:0 rcv_rtt:61.377
This, for instance, shows that we're not congestion controlling ACKs,
as the above output is in the ttcp receiving host, and ttcp is a one
way app, i.e. the received never calls sendmsg, so
ccid_hc_tx_send_packet is never called, so the TX half connection
stays in TFRC_SSTATE_NO_SENT state and hctx_rtt is never calculated,
stays with the value set in ccid3_hc_tx_init, 4us, as show above in
milliseconds (0.004ms), upcoming patches will fix this.
rcv_rtt seems sane tho, matching ping results :-)

Subject: [PATCH 811/997] [AX25/NETROM]: Cleanup direct calls into IP stack
Get rid of the calls to ip_rcv and arp_rcv which were layering
violations anyway. With those being replaced by netif_rx, less parts
of AX.25 and relatives depend on INET support actually being enabled.
This also will make PF_PACKET sockets work for IP and ARP packets
received over AX.25 and for IP packets over NET/ROM.

All these are claiming to include <net/ip.h> to get ip_rcv() but in
fact don't need the header at all, so away with the inclusion.

Subject: [PATCH 816/997] [BNX2]: Fix rtnl deadlock in bnx2_close
This fixes an rtnl deadlock problem when flush_scheduled_work() is
called from bnx2_close(). In rare cases, linkwatch_event() may be on
the workqueue from a previous close of a different device and it will
try to get the rtnl lock which is already held by dev_close().
The fix is to set a flag if we are in the reset task which is run
from the workqueue. bnx2_close() will loop until the flag is cleared.
As suggested by Jeff Garzik, the loop is changed to call msleep(1)
instead of yield() in the original patch.
flush_scheduled_work() is also moved to bnx2_remove_one() before the
netdev is freed.

Subject: [PATCH 817/997] [BNX2]: speedup serdes linkup
This speeds up link-up time on 5706 SerDes if the link partner does
not autoneg, a rather common scenario in blade servers. Some blade
servers use IPMI for keyboard input and it's important to minimize
link disruptions.
The speedup is achieved by shortening the timer to (HZ / 3) during
the transient period right after initiating a SerDes autoneg. If
autoneg does not complete, parallel detect can be done sooner. After
the transient period is over, the timer goes back to its normal HZ
interval.
As suggested by Jeff Garzik, the timer initialization is moved to
bnx2_init_board() from bnx2_open().
An eeprom bit is also added to allow default forced SerDes speed for
even faster link-up time.

Subject: [PATCH 818/997] [BNX2]: remove atomics in tx
Remove atomic operations in the fast tx path. Expensive atomic
operations were used to keep track of the number of available tx
descriptors. The new code uses the difference between the consumer
and producer index to determine the number of free tx descriptors.
As suggested by Jeff Garzik, the name of the inline function is
changed to all lower case.

Subject: [PATCH 820/997] [BNX2]: update version and minor fixes
Update version and add 4 minor fixes, the last 2 were suggested by
Jeff Garzik:
1. check for a valid ethernet address before setting it
2. zero out bp->regview if init_one encounters an error and unmaps
the IO address. This prevents remove_one from unmapping again.
3. use netif_rx_schedule() instead of hand coding the same.
4. use IRQ_HANDLED and IRQ_NONE.

Attached the implementation of the Boyer-Moore string search
algorithm for the new textsearch infrastructure.
I've added as well a note about the limitations that this approach
presents, as Thomas has remarked.

Subject: [PATCH 825/997] [NET]: use __read_mostly on kmem_cache_t ,
DEFINE_SNMP_STAT pointers
This patch puts mostly read only data in the right section
(read_mostly), to help sharing of these data between CPUS without
memory ping pongs.
On one of my production machine, tcp_statistics was sitting in a
heavily modified cache line, so *every* SNMP update had to force a
reload.

Subject: [PATCH 827/997] [DCCP]: Introduce dccp_wait_for_ccid and use it in
dccp_write_xmit
This is not quite what I think we should have long term but improves
performance for now, so lets use it till we get CCID3 working well,
then we can think about using sk_write_queue, perhaps using some ideas
from Juwen Lai's old stack for 2.4.20.

From b6ee3d4ada4e85d9b9b9164c1327ef0850c79d5e Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@mandriva.com>
Date: Sat, 27 Aug 2005 18:18:18 -0300
Subject: [PATCH 829/997] [CCID3]: Reorganise timeval handling
Introducing functions to add to or subtract from a timeval variable
and renaming now_delta to timeval_new_delta that calls do_gettimeofday
and then timeval_delta, that should be used when there are several
deltas made relative to the current time or setting variables to it,
so as to avoid calling do_gettimeofday excessively.
I'm leaving these "timeval_" prefixed funcions internal to DCCP for a
while till we're sure there are no subtle bugs in it.
It also is more correct as it checks if the number of usecs added to
or subtracted from a tv_usec field is more than 2 seconds.

loss_interval.[ch]
And put this into net/dccp/ccids/lib/, where packet_history.[ch] will also be
moved and then we'll have a tfrc_lib.ko module that will be used by
dccp_ccid3.ko and other CCIDs that are variations of TFRC (RFC 3448).

Subject: [PATCH 834/997] [DCCP]: Introduce dccp_tfrc_lib module with
net/dccp/ccids/lib/*.c
I'll now take a look at the other proposed TFRC DCCP CCIDs to find
more code that is now in ccid3.c and move to this module, the loss
event rate, calc_X, etc most probably will be moved there.
The main goal of these changes is to pave the way for the
implementation of more TFRC based DCCP CCIDs and to shrink ccid3.c,
reducing its complexity and helping in getting it rock solid.

-/* Calculate the send rate as per section 3.1 of RFC3448
-
-Returns send rate in bytes per second
-
-Integer maths and lookups are used as not allowed floating point in kernel
-
-The function for Xcalc as per section 3.1 of RFC3448 is:
-
-X = s
- -------------------------------------------------------------
- R*sqrt(2*b*p/3) + (t_RTO * (3*sqrt(3*b*p/8) * p * (1+32*p^2)))
-
-where
-X is the trasmit rate in bytes/second
-s is the packet size in bytes
-R is the round trip time in seconds
-p is the loss event rate, between 0 and 1.0, of the number of loss events
- as a fraction of the number of packets transmitted
-t_RTO is the TCP retransmission timeout value in seconds
-b is the number of packets acknowledged by a single TCP acknowledgement
-
-we can assume that b = 1 and t_RTO is 4 * R. With this the equation becomes:
-
-X = s
- -----------------------------------------------------------------------
- R * sqrt(2 * p / 3) + (12 * R * (sqrt(3 * p / 8) * p * (1 + 32 * p^2)))
-
-
-which we can break down into:
-
-X = s
- --------
- R * f(p)
-
-where f(p) = sqrt(2 * p / 3) + (12 * sqrt(3 * p / 8) * p * (1 + 32 * p * p))
-
-Function parameters:
-s - bytes
-R - RTT in usecs
-p - loss rate (decimal fraction multiplied by 1,000,000)
-
-Returns Xcalc in bytes per second
-
-DON'T alter this code unless you run test cases against it as the code
-has been manipulated to stop underflow/overlow.

+/* Calculate the send rate as per section 3.1 of RFC3448
+
+Returns send rate in bytes per second
+
+Integer maths and lookups are used as not allowed floating point in kernel
+
+The function for Xcalc as per section 3.1 of RFC3448 is:
+
+X = s
+ -------------------------------------------------------------
+ R*sqrt(2*b*p/3) + (t_RTO * (3*sqrt(3*b*p/8) * p * (1+32*p^2)))
+
+where
+X is the trasmit rate in bytes/second
+s is the packet size in bytes
+R is the round trip time in seconds
+p is the loss event rate, between 0 and 1.0, of the number of loss events
+ as a fraction of the number of packets transmitted
+t_RTO is the TCP retransmission timeout value in seconds
+b is the number of packets acknowledged by a single TCP acknowledgement
+
+we can assume that b = 1 and t_RTO is 4 * R. With this the equation becomes:
+
+X = s
+ -----------------------------------------------------------------------
+ R * sqrt(2 * p / 3) + (12 * R * (sqrt(3 * p / 8) * p * (1 + 32 * p^2)))
+
+
+which we can break down into:
+
+X = s
+ --------
+ R * f(p)

+where f(p) = sqrt(2 * p / 3) + (12 * sqrt(3 * p / 8) * p * (1 + 32 * p * p))

+s - bytes
+R - RTT in usecs
+p - loss rate (decimal fraction multiplied by 1,000,000)

Some shub2 changes were not in the tree when Greg cleaned up the sn2

one didn't get fixed.

Subject: [PATCH 841/997] [DCCP]: Introduce DCCP_SOCKOPT_PACKET_SIZE
So that applications can set dccp_sock->dccps_pkt_size, that in turn
is used in the CCID3 half connection init routines to set
ccid3hc[tr]x_s and use it in its rate calculations.

Subject: [PATCH 842/997] [CCID3]: Call sk->sk_write_space(sk) when receiving a
feedback packet
This makes the send rate calculations behave way more closely to what
is specified, with the jitter previously seen on x and x_recv
disappearing completely on non lossy setups.
This resembles the tcp_data_snd_check code, that possibly we'll end up
using in DCCP as well, perhaps moving this code to
inet_connection_sock.
For now I'm doing the simplest implementation tho.

Subject: [PATCH 843/997] [PATCH] Lazy page table copies in fork()
Defer copying of ptes until fault time when it is possible to reconstruct
the pte from backing store. Idea from Andi Kleen and Nick Piggin.
Thanks to input from Rik van Riel and Linus and to Hugh for correcting
my blundering.
Ray Fucillo <fucillo@intersystems.com> reports:
"I applied this latest patch to a 2.6.12 kernel and found that it does
resolve the problem. Prior to the patch on this machine, I was
seeing about 23ms spent in fork for ever 100MB of shared memory
segment.
After applying the patch, fork is taking about 1ms regardless of the
shared memory size."

Subject: [PATCH 846/997] [PATCH] fix iSeries build for gcc-3.4
gcc 3.4 (at least the build we are using) puts the gcc generated .ident
string into a .note section at the end of the files it compiles (gcc
3.3.3-hammer and gcc 4.0.2 Debian puts it in the .text section). This
means that the lparmap.s file we produce in the iSeries build may end with
a .note section. When we include it into head.S, the assembler can no
longer resolve some of the conditional branches since the target label
ends up too far away. This patch just forces us back to the .text section
after including lparmap.s.
The breakage was caused by my patch "iSeries build with newer assemblers
and compilers" (sha1-id: 2ad56496627630ebc99f06af5f81ca23e17e014e).

From 71d276d751ff5ddba28312aecefb174b20a5b970 Mon Sep 17 00:00:00 2001
From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Wed, 17 Aug 2005 16:41:44 +1000
Subject: [PATCH 849/997] [PATCH] Create vio_bus_ops
Create vio_bus_ops so that we just pass a structure to vio_bus_init
instead of three separate function pointers.
Rearrange vio.h to avoid forward references. vio.h only needs
struct device_node from prom.h so remove the include and just
declare it.

Subject: [PATCH 851/997] [PATCH] Create include/asm-powerpc
The ppc and ppc64 trees are hopefully going to merge over time, so this
patch begins the process by creating a place for the merging of the
header files.
Create include/asm-powerpc (and move linkage.h into it from
asm-{ppc,ppc64} since we don't like empty directories). Modify the
ppc and ppc64 Makefiles to cope.

Subject: [PATCH 854/997] [PATCH] PPC64: Don't try to claim memory from OF at
1GB mark
Some RS64-based machines (p620, F80, others) have problems with firmware
returning 0xdeadbeef instead of failure to allocations that end at the
1GB mark.
We have two options:
1. Detect the undocumented 0xdeadbeef return value and interpret it as
a failure.
2. Avoid allocating that high.
(2) is really the cleaner solution here. 768MB is plenty of room so use
that as the max alloc_top instead of 1GB.

Subject: [PATCH 859/997] [PATCH] Remove nested feature sections
The {BEGIN,END}_FTR_SECTION asm macros used in ppc64 to nop out
sections of code at runtime cannot be nested. However, we do nest
them in hash_low.S. We get away with it there, because there is
nothing between the BEGIN markers for each section. However, that's
confusing to someone reading the code.
This patch removes the nested ifset and ifclr feature sections,
replacing them with a single feature section in the full mask/value
form.

Subject: [PATCH 867/997] [ALSA] sound - fix .iface field of mixer control
elements
Documentation,CS46xx driver,EMU10K1/EMU10K2 driver,AD1848 driver
SB16/AWE driver,CMIPCI driver,ENS1370/1+ driver,RME32 driver
RME96 driver,ICE1712 driver,ICE1724 driver,KORG1212 driver
RME HDSP driver,RME9652 driver
This patch changes .iface to SNDRV_CTL_ELEM_IFACE_MIXER whre _PCM or
_HWDEP was used in controls that are not associated with a specific PCM
(sub)stream or hwdep device, and changes some controls that got
inconsitent .iface values due to copy+paste errors. Furthermore, it
makes sure that all control that do use _PCM or _HWDEP use the correct
number in the .device field.

From 0ca06a00e206b963587ac471e6d1c52bf33b9a18 Mon Sep 17 00:00:00 2001
From: Liam Girdwood <liam.girdwood@wolfsonmicro.com>
Date: Fri, 29 Jul 2005 16:13:36 +0200
Subject: [PATCH 868/997] [ALSA] AC97 bus interface for ad-hoc drivers
AC97 Codec,PCI drivers
I've made the review changes and as requested I've pasted the RFC by
Nicolas below:-
'I would like to know what people think of the following patch. It
allows for a codec on an AC97 bus to be shared with other drivers which
are completely unrelated to audio. It registers a new bus type, and
whenever a codec instance is created then a device for it is also
registered with the driver model using that bus type. This allows, for
example, to use the extra features of the UCB1400 like the touchscreen
interface and the additional GPIOs and ADCs available on that chip for
battery monitoring. I have a working UCB1400 touchscreen driver here
that simply registers with the driver model happily working alongside
with audio features using this.'
Changes over RFC:-
o Now matches codec name within codec group.
o Added ac97_dev_release() to stop kernel complaining about no release
method for device.
o Added 'config SND_AC97_BUS' to sound/pci/Kconfig and moved 'config
SND_AC97_CODEC' out with the PCI=n statement.
o module is now called snd-ac97-bus

Subject: [PATCH 872/997] [ALSA] use PCM interface for IEC958 controls
Digigram VX core,ENS1370/1+ driver,CA0106 driver,EMU10K1/EMU10K2 driver
RME HDSP driver,RME9652 driver
For consistency, use the PCM interface instead of MIXER for IEC958
default/mask/stream mixer controls.

Subject: [PATCH 874/997] [ALSA] PXA27x AC97 warm reset
ARM PXA2XX driver
This patch extends the period of an AC97 warm reset on the PXA27x from
50uS to 500uS. The shorter reset didn't always guarantee that the codec
would wake up.
Changes:-
o Change pxa27x warm reset period to 500uS
o Removed double semi-colon.

From 443feb882679e21ba5d1e0ff9eff067ac26d9461 Mon Sep 17 00:00:00 2001
From: Karsten Wiese <annabellesgarden@yahoo.de>
Date: Wed, 10 Aug 2005 11:18:19 +0200
Subject: [PATCH 878/997] [ALSA] ALSA's struct _snd_pcm_substream: Obsolete
open_flag
PCM Midlevel,ALSA<-OSS emulation,USB USX2Y
This patch removes open_flag from struct _snd_pcm_substream.
All of its uses are substituted by querying struct _snd_pcm_substream's
member ffile instead.

Subject: [PATCH 882/997] [ALSA] usb-audio: use 1 ms URBs when capturing
USB generic driver
When capturing audio data, we do not know beforehand how many samples
the device sends per frame, so we have to use URBs that are as short as
possible to make sure that we can handle period boundaries without any
additional latencies.
Furthermore, the total count of URBs submitted doesn't matter when
capturing, so we can just use the maximum number.

Subject: [PATCH 883/997] [ALSA] usb-audio: fix packets per URB calculation for

USB generic driver
When determining how many packets are needed for one period, we cannot
assume that all packets have their maximum size -- we always use the
nominal sample rate when sending data, and could use an even lower rate
when the endpoint uses frequency feedback.

The EHCI driver doesn't interrupt more than once per millisecond, and
organizes all iso transfers with frame-sized ITDs, so we can (try to)
be more efficient by aligning all URBs on frame boundaries.

Subject: [PATCH 893/997] [ALSA] usb-audio: optimize handling of capture URBs
USB generic driver
When preparing capture URBs, we don't need to stop when we cross a
period boundary because we now never handle more than one millisecond of
data per URB anyway.
When handling captured data, use an extra flag to call
snd_pcm_period_elapsed() no more than once. This allows us to move the
period boundary checking code before the copying of the data which
avoids a second locking of the substream's lock.

Subject: [PATCH 894/997] [ALSA] usb-audio: double-buffer all playback data
USB generic driver
We always had to use double buffering when capturing, and when playback
data for one URB crosses a buffer boundary. The latter would make hwptr
updates less precise because the double-buffered data is read from the
buffer much earlier than the other data is read by the host controller.
Double-buffering all data allows to update hwptr immediately after the
data was copied to the USB buffer(s), which has the additional benefit
of avoiding the latency imposed by the host controller's delay of up to
one frame when interrupting.

Subject: [PATCH 898/997] [ALSA] usb-audio: use vmalloc for the PCM buffer
USB generic driver
With the double buffering, we no longer need contiguous memory for the
PCM buffer, so we can use vmalloc() instead of the preallocation
functions, and increase the maximum size to 256 KB.

Intel8x0 driver,AC97 Codec
The HP nx6110 laptop needs to have Headphone Jack Sense enabled so
that the internal speakers will be turned off when headphones are
plugged in.
Also ac97_quirk=hp_only is needed to make a single Master volume in
the mixer instead of separate volumes for internal speakers and
headphones, which just confuses the user.

Subject: [PATCH 936/997] [PATCH] x86: pci_assign_unassigned_resources() update
I had some time to think about PCI assign issues in 2.6.13-rc series.
The major problem here is that we call pci_assign_unassigned_resources()
way too early - at subsys_initcall level. Therefore we give no chances
to ACPI and PnP routines (called at fs_initcall level) to reserve their
respective resources properly, as the comments in drivers/pnp/system.c
and drivers/acpi/motherboard.c suggest:
/**
* Reserve motherboard resources after PCI claim BARs,
* but before PCI assign resources for uninitialized PCI devices
*/
So I moved the pci_assign_unassigned_resources() call to
pcibios_assign_resources() (fs_initcall), which should hopefully fix a
lot of problems and make PCIBIOS_MIN_IO tweaks unnecessary.
Other changes:
- remove resource assignment code from pcibios_assign_resources(), since
it duplicates pci_assign_unassigned_resources() functionality and
actually does nothing in 2.6.13;
- modify ROM assignment code as per Ben's suggestion: try to use firmware
settings by default (if PCI_ASSIGN_ROMS is not set);
- set CARDBUS_IO_SIZE back to 4K as it's a wonderful stress test for
various setups.
Confirmed by Tero Roponen <teanropo@cc.jyu.fi> (who had problems with
the 4kB CardBus IO size previously).

Subject: [PATCH 942/997] [ARM] 2867/2: unaligned ldrd/strd fixups
Patch from Steve Longerbeam
Adds an implementation of unaligned LDRD and STRD fixups.
Also fixes a bug where do_alignment() would misinterpret and
fixup an unaligned LDRD/STRD as LDRH/STRH, causing memory
corruption.
This is the same as Patch #2867/1, but with minor whitespace
and comments changes, plus a check for arch-level >= v5TE
before printing ai_dword count in proc_alignment_read().

Currently the iseries_veth driver prints the file name and line number in its
error messages. This isn't very useful for most users, so just print
"iseries_veth: message" instead.
- convert uses of veth_printk() to veth_debug()/veth_error()/veth_info()
- make terminology consistent, ie. always refer to LPAR not lpar
- be consistent about printing return codes as %d not %x
- make format strings fit in 80 columns

Subject: [PATCH 949/997] [PATCH] iseries_veth: Remove a FIXME WRT deletion of
the ack_timer
The iseries_veth driver has a timer which we use to send acks. When the
connection is reset or stopped we need to delete the timer.
Currently we only call del_timer() when resetting a connection, which means
the timer might run again while the connection is being re-setup. As it turns
out that's ok, because the flags the timer consults have been reset.
It's cleaner though to call del_timer_sync() once we've dropped the lock,
although the timer may still run between us dropping the lock and calling
del_timer_sync(), but as above that's ok.

Subject: [PATCH 950/997] [PATCH] iseries_veth: Try to avoid pathological reset
behaviour
The iseries_veth driver contains a state machine which is used to manage
how connections are setup and neogotiated between LPARs.
If one side of a connection resets for some reason, the two LPARs can get
stuck in a race to re-setup the connection. This can lead to the connection
being declared dead by one or both ends. In practice the connection is
declared dead by one or both ends approximately 8/10 times a connection is
reset, although it is rare for connections to be reset.
(an example here: http://michael.ellerman.id.au/files/misc/veth-trace.html)
The core of the problem is that the end that resets the connection doesn't
wait for the other end to become aware of the reset. So the resetting end
starts setting the connection back up, and then receives a reset from the
other end (which is the response to the initial reset). And so on.
We're severely limited in what we can do to fix this. The protocol between
LPARs is essentially fixed, as we have to interoperate with both OS/400
and old Linux drivers. Which also means we need a fix that only changes the
code on one end.
The only fix I've found given that, is to just blindly sleep for a bit when
resetting the connection, in the hope that the other end will get itself
sorted. Needless to say I'd love it if someone has a better idea.
This does work, I've so far been unable to get it to break, whereas without
the fix a reset of one end will lead to a dead connection ~8/10 times.

Subject: [PATCH 951/997] [PATCH] iseries_veth: Fix broken promiscuous handling
Due to a logic bug, once promiscuous mode is enabled in the iseries_veth
driver it is never disabled.
The driver keeps two flags, promiscuous and all_mcast which have exactly the
same effect. This is because we only ever receive packets destined for us,
or multicast packets. So consolidate them into one promiscuous flag for
simplicity.

The iseries_veth driver keeps a stack of messages for each connection

which makes the message stack lock redundant.
Remove the message stack lock and document the fact that callers of the
stack-manipulation functions must hold the connection's lock.

Rework the code a bit to keep the return value from dma_unmap_single()
around, and then check if it's a dma_mapping_error() before we do
the dma_unmap_single().

Subject: [PATCH 955/997] [PATCH] iseries_veth: Make init_connection() &
destroy_connection() symmetrical
This patch makes veth_init_connection() and veth_destroy_connection()
symmetrical in that they allocate/deallocate the same data.
Currently if there's an error while initialising connections (ie. ENOMEM)
we call veth_module_cleanup(), however this will oops because we call
driver_unregister() before we've called driver_register(). I've never seen
this actually happen though.
So instead we explicitly call veth_destroy_connection() for each connection,
any that have been set up will be deallocated.
We also fix a potential leak if vio_register_driver() fails.

Subject: [PATCH 956/997] [PATCH] iseries_veth: Use kobjects to track lifecycle
of connection structs
The iseries_veth driver can attach to multiple vlans, which correspond to
multiple net devices. However there is only 1 connection between each LPAR,
so the connection structure may be shared by multiple net devices.
This makes module removal messy, because we can't deallocate the connections
until we know there are no net devices still using them. The solution is to
use ref counts on the connections, so we can delete them (actually stop) as
soon as the ref count hits zero.
This patch fixes (part of) a bug we were seeing with IPv6 sending probes to
a dead LPAR, which would then hang us forever due to leftover skbs.

Subject: [PATCH 958/997] [PATCH] iseries_veth: Add a per-connection ack timer
Currently the iseries_veth driver contravenes the specification in
Documentation/networking/driver.txt, in that if packets are not acked by
the other LPAR they will sit around forever.
This patch adds a per-connection timer which fires if we've had no acks for
five seconds. This is superior to the generic TX timer because it catches
the case of a small number of packets being sent and never acked.
This fixes a bug we were seeing on real systems, where some IPv6 neighbour
discovery packets would not be acked and then prevent the module from being
removed, due to skbs lying around.

Subject: [PATCH 959/997] [PATCH] iseries_veth: Simplify full-queue handling
The iseries_veth driver often has multiple netdevices sending packets over
a single connection to another LPAR. If the bandwidth to the other LPAR is
exceeded, all the netdevices must have their queues stopped.
The current code achieves this by queueing one incoming skb on the
per-netdevice port structure. When the connection is able to send more packets
we iterate through the port structs and flush any packet that is queued,
as well as restarting the associated netdevice's queue.
This arrangement makes less sense now that we have per-connection TX timers,
rather than the per-netdevice generic TX timer.
The new code simply detects when one of the connections is full, and stops
the queue of all associated netdevices. Then when a packet is acked on that
connection (ie. there is space again) all the queues are woken up.

Subject: [PATCH 960/997] [PATCH] iseries_veth: Fix bogus counting of TX errors
There's a number of problems with the way iseries_veth counts TX errors.
Firstly it counts conditions which aren't really errors as TX errors. This
includes if we don't have a connection struct for the other LPAR, or if the
other LPAR is currently down (or just doesn't want to talk to us). Neither
of these should count as TX errors.
Secondly, it counts one TX error for each LPAR that fails to accept the packet.
This can lead to TX error counts higher than the total number of packets sent
through the interface. This is confusing for users.
This patch fixes that behaviour. The non-error conditions are no longer
counted, and we introduce a new and I think saner meaning to the TX counts.
If a packet is successfully transmitted to any LPAR then it is transmitted
and tx_packets is incremented by 1.
If there is an error transmitting a packet to any LPAR then that is counted
as one error, ie. tx_errors is incremented by 1.

Subject: [PATCH 965/997] [PATCH] iseries_veth: Be consistent about driver
name, increment version
The iseries_veth driver tells sysfs that it's called 'iseries_veth', but if
you ask it via ethtool it thinks it's called 'veth'. I think this comes from
2.4 when the driver was called 'veth', but it's definitely called
'iseries_veth' now, so fix it.
To make sure we don't do it again define DRV_NAME and use it everywhere.
While we're at it, change the version number to 2.0, to reflect the changes
made in this patch series.

prism2_pccard_card_present()
local->hw_priv was initialized only after the interrupt handler was
registered. This could trigger a NULL pointer dereference in
prism2_pccard_card_present() that assumed that local->hw_priv is always
set (and it should have been). Fix this by setting local->hw_priv before
registering the interrupt handler.

Subject: [PATCH 967/997] [ARM] 2865/2: fix fadvise64_64 syscall argument
passing
Patch from Nicolas Pitre
The prototype for sys_fadvise64_64() is:
long sys_fadvise64_64(int fd, loff_t offset, loff_t len, int advice)
The argument list is therefore as follows on legacy ABI:
fd: type int (r0)
offset: type long long (r1-r2)
len: type long long (r3-sp[0])
advice: type int (sp[4])
With EABI this becomes:
fd: type int (r0)
offset: type long long (r2-r3)
len: type long long (sp[0]-sp[4])
advice: type int (sp[8])
Not only do we have ABI differences here, but the EABI version requires
one additional word on the syscall stack.
To avoid the ABI mismatch and the extra stack space required with EABI
this syscall is now defined with a different argument ordering
on ARM as follows:
long sys_arm_fadvise64_64(int fd, int advice, loff_t offset, loff_t len)
This gives us the following ABI independent argument distribution:
fd: type int (r0)
advice: type int (r1)
offset: type long long (r2-r3)
len: type long long (sp[0]-sp[4])
Now, since the syscall entry code takes care of 5 registers only by
default including the store of r4 to the stack, we need a wrapper to
store r5 to the stack as well. Because that wrapper was missing and was
always required this means that sys_fadvise64_64 never worked on ARM and
therefore we can safely reuse its syscall number for our new
sys_arm_fadvise64_64 interface.

Subject: [PATCH 976/997] [PATCH] Fix bug in ppc64 dynamic hugepage support
In adjusting the logic for SLB miss for the dynamic hugepage stuff, I
messed up the !CONFIG_HUGETLB_PAGE case, failing to set the SLB flags
properly.
This fixes it. It also streamlines the logic for the HUGETLB_PAGE case
(removing a couple of branches) while we're at it.
Booted, and roughly tested on POWER5 (with and without HUGETLB_PAGE),
iSeries/RS64 (no hugepage available), and G5 (with and without
HUGETLB_PAGE).

Subject: [PATCH 977/997] [PATCH] Fix PCI ROM mapping
This fixes a problem with pci_map_rom() which doesn't properly
update the ROM BAR value with the address thas allocated for it by the
PCI code. This problem, among other, breaks boot on Mac laptops.
It'ss a new version based on Linus latest one with better error
checking.

support
New architecture and board configuration support for m68knommu.
. add 523x ColdFire support
. add support for SOM5282 and MOD5272 boards
. break up the 527x to be separate 5271 and 5275. There is some
subtle differences that (like RAM config) that need to be dealt with
. add option to support selecting 4k kernel stack

Subject: [PATCH 991/997] [PATCH] uclinux: use MAP_PRIVATE when mmaping code
regions in flat binary loader
Use MAP_PRIVATE when calling mmap to get memory for the code region.
The flat loader was using MAP_SHARED, but underlying changes to the
MMUless mmap means this is now wrong.
