2017-02-03kbuild: modversions: add infrastructure for emitting relative CRCsArd Biesheuvel
This add the kbuild infrastructure that will allow architectures to emit vmlinux symbol CRCs as 32-bit offsets to another location in the kernel where the actual value is stored. This works around problems with CRCs being mistaken for relocatable symbols on kernels that self relocate at runtime (i.e., powerpc with CONFIG_RELOCATABLE=y) For the kbuild side of things, this comes down to the following: - introducing a Kconfig symbol MODULE_REL_CRCS - adding a -R switch to genksyms to instruct it to emit the CRC symbols as references into the .rodata section - making modpost distinguish such references from absolute CRC symbols by the section index (SHN_ABS) - making kallsyms disregard non-absolute symbols with a __crc_ prefix Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2017-01-18gcc-plugins: Add structleak for more stack initializationKees Cook
This plugin detects any structures that contain __user attributes and makes sure it is being fully initialized so that a specific class of information exposure is eliminated.

Documentation for array parameters passed in a function, like the first argument in the function below, weren't getting exported in the rst format, although they work fine for html and pdf formats: void drm_clflush_pages(struct page * pages[], unsigned long num_pages) That's because the string key to store the description in the parameterdescs dictionary doesn't have the [] suffix.

2017-01-04kernel-doc: make highlights more homogenous for the various backendsPaolo Bonzini
$type_struct_full and friends are only used by the restructuredText backend, because it needs to separate enum/struct/typedef/union from the name of the type. However, $type_struct is *also* used by the rST backend. This is confusing. This patch replaces $type_struct's use in the rST backend with a new $type_fallback; it modifies $type_struct so that it can be used in the rST backend; and creates regular expressions like $type_struct for enum/typedef/union, for use in all backends. Note that, compared to $type_*_full, in the new regexes $1 includes both the "kind" and the name (before, $1 was pretty much a constant).

2017-01-04kernel-doc: make member highlighting available in all backendsPaolo Bonzini
Note that, in order to produce the correct Docbook markup, the "." or "->" must be separated from the member name in the regex's captured fields. For consistency, this change is applied to $type_member and $type_member_func too, not just to $type_member_xml. List mode only prints the struct name, to avoid any undesired change in the operation of docproc.

2017-01-04kernel-doc: strip attributes even if they have an argumentPaolo Bonzini
An inline function can have an attribute, as in include/linux/log2.h, and kernel-doc handles this already for simple cases. However, some attributes have arguments (e.g. the "target" attribute). Handle those too. Furthermore, attributes could be at the beginning of a function declaration, before the return type. To correctly handle this case, you need to strip spaces after the attributes; otherwise, dump_function is left confused.

2016-12-21selinux: use the kernel headers when building scripts/selinuxPaul Moore
Commit 3322d0d64f4e ("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.

2016-12-14sign-file: Fix inplace signing when src and dst names are both specifiedAlex Yashchenko
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); } ...
