Subject: Clarification of labeled IPsec checks
Date: Fri, 3 May 2013 15:11:48 -0400 [thread overview]
Message-ID: <51840BF4.7000302@tresys.com> (raw)
I'm doing some spring cleaning on refpolicy, cleaning out some old unused/unnecessary networking permissions. I'm trying to make sure I have the permissions checks straight, since labeled networking isn't common use. For labeled IPsec, we have the following permissions (assuming all policy capabilities are on--assume maximum checks):
netif: ingress/egress
node: sendto/recvfrom
peer: recv
association: sendto/recvfrom
I'm told that association perms are checked in the following cases:
sendto: when a packet leaves the box (legacy only) and when a SA/flow is checked
recvfrom: when an incoming packet is queued on a socket (legacy only)
Does "legacy only" mean the checks will eventually go away, or is it for a legacy IPsec configuration?
