-Subject: [PATCH] [sanitizer] Remove crypt and crypt_r interceptors
-
-From Florian Weimer's D144073
-
-> On GNU/Linux (glibc), the crypt and crypt_r functions are not part of the main shared object (libc.so.6), but libcrypt (with multiple possible sonames). The sanitizer libraries do not depend on libcrypt, so it can happen that during sanitizer library initialization, no real implementation will be found because the crypt, crypt_r functions are not present in the process image (yet). If its interceptors are called nevertheless, this results in a call through a null pointer when the sanitizer library attempts to forward the call to the real implementation.
->
-> Many distributions have already switched to libxcrypt, a library that is separate from glibc and that can be build with sanitizers directly (avoiding the need for interceptors). This patch disables building the interceptor for glibc targets.
-
-Let's remove crypt and crypt_r interceptors (D68431) to fix issues with
-newer glibc.
-
-For older glibc, msan will not know that an uninstrumented crypt_r call
-initializes `data`, so there is a risk for false positives. However, with some
-codebase survey, I think crypt_r uses are very few and the call sites typically
-have a `memset(&data, 0, sizeof(data));` anyway.

-    [sanitizer] Remove #include <linux/fs.h> to resolve fsconfig_command/mount_attr conflict with glibc 2.36
-    
-    It is generally not a good idea to mix usage of glibc headers and Linux UAPI
-    headers (https://sourceware.org/glibc/wiki/Synchronizing_Headers). In glibc
-    since 7eae6a91e9b1670330c9f15730082c91c0b1d570 (milestone: 2.36), sys/mount.h
-    defines `fsconfig_command` which conflicts with linux/mount.h:
-    
-        .../usr/include/linux/mount.h:95:6: error: redeclaration of ‘enum fsconfig_command’
-    
-    Remove #include <linux/fs.h> which pulls in linux/mount.h. Expand its 4 macros manually.
-    
-    Fix https://github.com/llvm/llvm-project/issues/56421
