Ilya Dryomov 193490dbe5 ceph: canonicalize server path in place ... commit b27a939e83 upstream. syzbot reported that 4fbc0c711b ("ceph: remove the extra slashes in the server path") had caused a regression where an allocation could be done under a spinlock -- compare_mount_options() is called by sget_fc() with sb_lock held. We don't really need the supplied server path, so canonicalize it in place and compare it directly. To make this work, the leading slash is kept around and the logic in ceph_real_mount() to skip it is restored. CEPH_MSG_CLIENT_SESSION now reports the same (i.e. canonicalized) path, with the leading slash of course. Fixes: 4fbc0c711b ("ceph: remove the extra slashes in the server path") Reported-by: syzbot+98704a51af8e3d9425a9@syzkaller.appspotmail.com Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Luis Henriques <lhenriques@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2020-04-13 10:48:11 +02:00
