Subject: Switch back to syscall()
Switch back to syscall() for the *xattr system calls. The current
mechanism of forwarding those calls to glibc breaks libraries like
libfakeroot (fakeroot) and libasan (the gcc address sanitizer; gcc
-fsanitize=address).
Those libraries provide wrappers for functions defined in other shared
libraries, usually glibc, do their own processing, and forward calls to
the original symbols looke dup via dlsym(RTLD_NEXT, "symbol_name"). In
our case, dlsym returns the libattr_*xattr wrappers. However, when our
wrappers try calling glibc, they end up calling the libfakeroot /
libasan wrappers instead because those override the original symbols =>
recursion.
The libattr_*xattr wrappers will only be used when symbols are looked up
at runtime (dlopen / dlsym). Programs linking against libattr will
directly use the glibc provided symbols. Therefore, the slightly worse
performance of syscall() won't affect any of the "normal" users of
libattr.
