Bruce Fields + +commit 22cf8419f1319ff87ec759d0ebdff4cbafaee832 upstream. + +The server is failing to apply the umask when creating new objects on +filesystems without ACL support. + +To reproduce this, you need to use NFSv4.2 and a client and server +recent enough to support umask, and you need to export a filesystem that +lacks ACL support (for example, ext4 with the "noacl" mount option). + +Filesystems with ACL support are expected to take care of the umask +themselves (usually by calling posix_acl_create). + +For filesystems without ACL support, this is up to the caller of +vfs_create(), vfs_mknod(), or vfs_mkdir(). + +Reported-by: Elliott Mitchell +Reported-by: Salvatore Bonaccorso +Tested-by: Salvatore Bonaccorso +Fixes: 47057abde515 ("nfsd: add support for the umask attribute") +Cc: stable@vger.kernel.org +Signed-off-by: J.
