I fail to see how those 2 are in any conflict. Smack namespace is just a mean of limiting the view of Smack labels within user namespace, to be able to give some limited capabilities to processes in the namespace to make it possible to partially administer Smack there. It doesn't change Smack behaviour or mode of operation in any way. If your approach here is to treat user ns mounted filesystem as if they didn't support xattrs at all then my patches don't conflict here any more than Smack itself already does. If the filesystem will get a default (e.g. by smack* mount options) label then this label will co-work with Smack namespaces. -- Lukasz Pawelczyk Samsung R&D Institute Poland Samsung Electronics -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
