2017-02-03kbuild: modversions: add infrastructure for emitting relative CRCsArd Biesheuvel4-5/+38
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>

2016-12-21selinux: use the kernel headers when building scripts/selinuxPaul Moore4-2/+14
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.

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); } ...

2016-12-12get_maintainer: look for arbitrary letter prefixes in sectionsJoe Perches1-3/+9
Jani Nikula proposes patches to add a few new letter prefixes for "B:" bug reporting and "C:" maintainer chatting to the various sections of MAINTAINERS. Add a generic mechanism to get_maintainer.pl to find sections that have any combination of "[A-Z]" letter prefix types in a section.

2016-12-12kasan: turn on -fsanitize-address-use-after-scopeAndrey Ryabinin1-0/+2
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 828347f8f9a5 ("kasan: support use-after-scope detection"). So, to make it work, we just have to enable use-after-scope in CFLAGS.

2016-12-11kconfig/nconf: Fix hang when editing symbol with a long promptBen Hutchings1-4/+11
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().
