Commit 3322d0d6 ("selinux: keep SELinux in sync with new capability definitions") added a check on the defined capabilities without explicitly including the capability header file which caused problems when building genheaders for users of clang/llvm. Resolve this by using the kernel headers when building genheaders, which is arguably the right thing to do regardless, and explicitly including the kernel's capability.h header file in classmap.h. We also update the mdp build, even though it wasn't causing an error we really should be using the headers from the kernel we are building. Reported-by:

When src and dst both are specified and they point to the same file the sign-file utility will write only signature to the dst file and the module (.ko file) body will not be written. That happens because we open the same file with "rb" and "wb" flags, from fopen man: w Truncate file to zero length or create text file for writing. The stream is positioned at the beginning of the file. ... bm = BIO_new_file(module_name, "rb"); ... bd = BIO_new_file(dest_name, "wb"); ... while ((n = BIO_read(bm, buf, sizeof(buf))), n > 0) { ERR(BIO_write(bd, buf, n) < 0, "%s", dest_name); } ...

In the upcoming gcc7 release, the -fsanitize=kernel-address option at first implied new -fsanitize-address-use-after-scope option. This would cause link errors on older kernels because they don't have two new functions required for use-after-scope support. Therefore, gcc7 changed default to -fno-sanitize-address-use-after-scope. Now the kernel has everything required for that feature since commit 828347f8 ("kasan: support use-after-scope detection"). So, to make it work, we just have to enable use-after-scope in CFLAGS.

Currently it is impossible to edit the value of a config symbol with a prompt longer than (terminal width - 2) characters. dialog_inputbox() calculates a negative x-offset for the input window and newwin() fails as this is invalid. It also doesn't check for this failure, so it busy-loops calling wgetch(NULL) which immediately returns -1. The additions in the offset calculations also don't match the intended size of the window. Limit the window size and calculate the offset similarly to show_scroll_win(). Cc: stable <stable@vger.kernel.org> Fixes: 692d97c3 ("kconfig: new configuration interface (nconfig)") Signed-off-by:

It is easy to forget adding/removing entries at the Documentation/00-INDEX file. In a matter of fact, even before ReST conversion, people use to forget adding things here, as there are lots of missing stuff out there. Now that we're doing a hard work converting entries to ReST, and while this hole file is not outdated, it is good to have some tool that would help to verify that this file is kept updated.

The root built-in.o archive is currently generated before all object files are built for the final link, due to final build of init/ after version update. In practice it seems like it doesn't matter because the archive symbol table does not change, but it is more logical to create the final archive as the last step. Signed-off-by:

This catches the failing ceph CRC on with: LD vmlinux.o MODPOST vmlinux.o WARNING: EXPORT symbol "ceph_monc_do_statfs" [vmlinux] version generation failed, symbol will not be versioned. When the modules referring to exported symbols are built, there is an existing warning for missing CRC, but it's not always the case such any such module will be built, and in any case it is useful to get a warning at the source. This gets a little verbose with CONFIG_DEBUG_SECTION_MISMATCH, producing a warning with each object linked, but I didn't think that warranted extra complexity to avoid. Signed-off-by: -

lib-ksyms.o is created by linking an empty input file with a linker script containing the interesting bits. Currently the empty input file is an archive containing nothing, however this causes the gold linker to segfault. I have opened a bug against gold https://sourceware.org/bugzilla/show_bug.cgi?id=20767 However this can be worked around by assembling an empty file to link with instead. The resulting lib-ksyms.o is slightly larger (seemingly due to empty .text, .data, .bss setions added), but final linked output should not be changed. Reported-by:

genksyms currently does not handle va_list. Add the __builtin_va_list keyword as a type.

THIN_ARCHIVES builds archives for built-in.o targets, have it build multi-y targets as archives as well. This saves another ~15% of the size of intermediate artifacts in the build tree. After this patch, the linker is only used in final link, and special cases like vdsos. Signed-off-by:

Nicholas Piggin authored
kallsyms generation is not foolproof, due to some linkers adding symbols (e.g., branch trampolines) when a binary size changes. Have it attempt a 3rd pass automatically if the kallsyms size changes in the 2nd pass. This allows powerpc64 allyesconfig to build without adding another pass when it's not required. This can be solved other ways by directing the linker not to add labels on branch stubs, or to move kallsyms near the end of the image. The former is undesirable for debugging/tracing, and the latter is a more significant change that requires more testing and review. Signed-off-by:
