eCryptfs: Copy up lower inode attrs after setting lower xattr
After passing through a ->setxattr() call, eCryptfs needs to copy the inode attributes from the lower inode to the eCryptfs inode, as they may have changed in the lower filesystem's ->setxattr() path. One example is if an extended attribute containing a POSIX Access Control List is being set. The new ACL may cause the lower filesystem to modify the mode of the lower inode and the eCryptfs inode would need to be updated to reflect the new mode. https://launchpad.net/bugs/926292 Signed-off-by: Tyler Hicks <tyhicks@canonical.com> Reported-by: Sebastien Bacher <seb128@ubuntu.com> Cc: John Johansen <john.johansen@canonical.com> Cc: <stable@vger.kernel.org>
