Subject: [PATCH 3/6] readlink("/proc/self/exe") overwrites buffer beyond its
return value
https://bugs.kde.org/show_bug.cgi?id=514094
Squashed cherry-picks:
Solaris: set VG_(resolved_exename) in load_client()
Haven't needed it yet, but I would like to try using it in the
readlink syscall wrapper.
(cherry picked from commit bf154d815a9fd7f4aaae97e31aa03cecf69448d4)
Bug 514094 - readlink("/proc/self/exe") overwrites buffer beyond its return value
Used the reproducer as the basis for a test on Solaris and Linux.
(cherry picked from commit 5c0f5e604bc3a4e8822ea59c488c123af6284afd)
readlink[at] syswrap: limit copy to bufsiz when path is proc self exe
(cherry picked from commit bd9edb8fcd0a8692d865e08fab2a573a4cde4c16)
Regtest: add missing readlinkat_self files
(cherry picked from commit 987034c44105cdc2f6f8d84751135d23bd5c37b6)
regtest: fix warning
Added a nice const named variable then didn't use it
(cherry picked from commit dae37ecd2692e0e5beba77c296c2648ebbf47637)
Fix bug514094,vgtest typo in none/tests/Makefile.am
(cherry picked from commit 294742a2d9f431fd2dcd73db161f67fb12ddd833)
syswrap readlink and linux readlinkat: check that buf is accessible for proc self exe case
Also update the t testcases to cover this.
(cherry picked from commit 8d8023d107699c7c2d97acf2dcb77bae71c0b1cf)
solaris readlinkat: check that buf is accessible for proc self path a.out
(cherry picked from commit 827a1b8c307a2eafa001788565e14af3445f2151)

Subject: [PATCH 6/6] Disable linux madvise MADV_GUARD_INSTALL
glibc 2.42+ (with linux 6.13+) uses MADV_GUARD_INSTALL to setup stack
guard pages. valgrind currently isn't able to track this and such
guard pages also don't show up in /proc maps (only in /proc pagemap
since linux 6.14). For now valgrind fails a madvise MADV_GUARD_INSTALL
syscall with EINVAL. This causes glibc to fall back to mprotect
PROT_NONE which valgrind is able to track.
