cover secid reconciliation-v02: Repost patchset with updates
The following are the changes included in this patchset since the previous post:
- Perform flow_in check before (as opposed to after) computing transition secid on inbound; this seems more intuitive and correct.
- Implement reconciliation and flow control for outbound traffic (forward case being a sequence of inbound checks followed by outbound checks).
- Make selinux_xfrm_postroute_last checks conditional on compat_net.
This patchset is relative to David Miller's net-2.6.19.git (last updated on Sep 1st).
Please consider for inclusion in 2.6.19.
UPCOMING WORK:
The following per the discussion at:
http://marc.theaimsgroup.com/?l=selinux&m=115755980516072&w=2
- Create IPSec SAs to be acquired with the creating sock's context as opposed to that of the matching SPD rule, resulting in a simpler SPD as well as policy.
- Set peer_sid on tcp sockets to the reconciled secmark so trusted applications can retrieve and service the data at the appropriate context.

Considering the discussions that have taken place on the SELinux list I think doing the work to set the peer_sid value on TCP sockets is an important part of the secid work and should be included in this patchset. I don't believe it would be that difficult, and it would make some of the code much cleaner/simpler I think.
