Description Andreas Schneider 2025-11-27 16:27:23 UTC 
libsmbclient posix extensions with SMB3 don't work at all.

a) smbc_setOptionPosixExtensions() doesn't do anything

b) smbc_fgetxattr() calls getxattr() without the *f*!
   This means smbc_fgetxattr(posix.attr.enabled) always returns -1.

Have patchset, need bug.
