[PATCH] D41053: Set of corrections for MSan/NetBSD

[Kamil Rytarowski via Phabricator via llvm-commits]

krytarowski added a project: Sanitizers.
Herald added subscribers: kubamracek, srhines.

Changes:

- Don't attempt to intercept GLIBC specific functions like __strtol_internal. This is required to stop intercepting it as we leak dlerror(3) for dlsym(3) that cannot manage to find a symbol.
- Correct interception of fstatat(2).
- Don't run a test for fgetgrent_r() that is missing on NetBSD.
- Correct link_map location (offset) in Obj_Entry on x86_64 and i386.
- Stop intercepting getpshared-like functions in pthread(3). This is feature is not enabled by default on NetBSD as it's unfinished.
- Switch intercepting from UTMP to UTMPX functions.
