Hi there Timothy,
You'll want to read the thread "[patch] security. namespace"
recently - see the linux-xfs list archives on oss.sgi.com.
The right way to implement this is to support the "security"
namespace in XFS. The attached (experimental) patch does
just that - there are missing pieces (xfsdump/xfsrestore do
not support this yet, etc), but this seems fairly stable so
far. The patch is from late last year, it will need a few
tweaks to work with the current CVS trees, but should apply
relatively cleanly to older trees and Marcelo's bk tree (but
not yet Andrew's/Linus' bk tree - thats a few changes behind
us just at the moment and will conflict on this one).
It needs some more testing, and technical discussion between
us SGI folks before this patch will be applied. (so please
don't follow up with "when will this be applied" questions ;)
Have fun.
cheers.
