core/setxattr: prevent users from setting glusterfs xattrs
* Each xlator prevents the user from setting glusterfs-internal xattrs like trusted.gfid by handling it in respective setxattr functions. The speacial case of trusted.gfid is handled in fuse (Not in posix because posix_setxattr is used to set gfid). * For xlators which did not define setxattr and/or fsetxattr, the functions have been implemented with appropriate checks. xlator | fops-added _______________|__________________________ | 1. afr | fsetxattr 2. stripe | setxatrr and fsetxattr 3. quota | setxattr and fsetxattr Change-Id: Ib62abb7067415b23a708002f884d30e8866fbf48 BUG: 765487 Signed-off-by: Rajesh Amaravathi <rajesh@redhat.com> Reviewed-on: http://review.gluster.com/685 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Amar Tumballi <amar@gluster.com>
