Thanks.

Yes it is, you need CAP_NET_ADMIN.  I guess this probably isn't that important
for 2.6.19 then ...

[Thanks for the pointer, didn't know that file was there]

... however, I still think this might qualify for the 2.6.19 stable kernel.
When a MLS sensitivity level or category maps to zero then whenever the NetLabel
subsystem is called to resolve the security attributes of a packet it will, in
certain configurations, return security attributes/contexts which are incorrect.

Please let me know if you think that has merit for the stable tree and I'll send
the patch to the stable mailing list.
