Subject: SELinux inode size gotcha in btrfs.
Date: Mon, 27 Feb 2012 22:18:55 +0000 (UTC)	[thread overview]

Hi All,


I've come across the 'gotcha' in XFS where the inode size defaults to 256 [1]
whereas for SELinux the attributes play better when you initialise it at
creation to 512.

>From my reading of the btrfs specs [2] it doesn't look like you'll get caught
with that as the inodes "will not contain embedded file data or extended
attribute data. These things are stored in other item types."

Have I read that right? I've seen xattr bugs patches etc but nothing that would
hit the SE Linux domain.
