2018-07-26libsanitizer: Mark REAL(swapcontext) with indirect_return attribute on x86H.J. Lu
Cherry-pick compiler-rt revision 337603: When shadow stack from Intel CET is enabled, the first instruction of all indirect branch targets must be a special instruction, ENDBR. lib/asan/asan_interceptors.cc has ... int res = REAL(swapcontext)(oucp, ucp); ... REAL(swapcontext) is a function pointer to swapcontext in libc. Since swapcontext may return via indirect branch on x86 when shadow stack is enabled, as in this case, int res = REAL(swapcontext)(oucp, ucp); ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This function may be returned via an indirect branch. Here compiler must insert ENDBR after call, like call *bar(%rip) endbr64 I opened an LLVM bug: https://bugs.llvm.org/show_bug.cgi?id=38207 to add the indirect_return attribute so that it can be used to inform compiler to insert ENDBR after REAL(swapcontext) call. We mark REAL(swapcontext) with the indirect_return attribute if it is available.

As mentioned in <http://gcc.gnu.org/ml/gcc/2018-03/msg00133.html> the bogus adjustment to 160 from 144 (which is reverted here), is a single-token commit in upstream r301307, an attempt to correct a failed build due to an upstream change to compile the runtime with D_FILE_OFFSET_BITS=64. The correct fix is here: just use the right include. Yes, user-struct-stat64-as-stat is actually 160 for MIPS o32 and I hear user-struct-stat is also 160 for n32. There are additional fields appended for user-struct-stat! I guess for MIPS it's as bad as it gets for mixing up kernel and user struct stat. The context of the patch doesn't show that in the #else there's the correct include, the one for <asm/stat.h> to get the kernel-struct-stat. If you can't compile it, IMHO the kernel headers are just too old; 3.2 is fine for example. * sanitizer_common/sanitizer_platform_limits_linux.cc: Do not take the shortcut to #include <sys/stat.h> for MIPS instead of the kernel <asm/stat.h>.
