Unfortunately fgetxattr() and flistxattr() don't work via O_PATH fds. Let's thus add fallbacks to go via /proc/self/fd/ in these cases. Also, let's merge all the various flavours we have here into singular implementations that can do everything we need: 1. malloc() loop handling 2. by fd, by path, or combination (i.e. a proper openat() like API) 3. work on O_PATH
