Frank Filz 7ee2cb7f32 nfs: Fix NFS v4 client handling of MAY_EXEC in nfs_permission. ... The problem is that permission checking is skipped if atomic open is possible, but when exec opens a file, it just opens it O_READONLY which means EXEC permission will not be checked at that time. This problem is observed by the following sequence (executed as root): mount -t nfs4 server:/ /mnt4 echo "ls" >/mnt4/foo chmod 744 /mnt4/foo su guest -c "mnt4/foo" Signed-off-by: Frank Filz <ffilzlnx@us.ibm.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Cc: stable@kernel.org Tested-by: Eugene Teo <eugeneteo@kernel.sg> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2009-05-18 20:11:12 -07:00
