From e4c1721642bbd42d8142f4811cde0588c28db51d Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Wed, 29 May 2013 07:36:25 +0000 Subject: xfrm: force a garbage collection after deleting a policy In some cases after deleting a policy from the SPD the policy would remain in the dst/flow/route cache for an extended period of time which caused problems for SELinux as its dynamic network access controls key off of the number of XFRM policy and state entries. This patch corrects this problem by forcing a XFRM garbage collection whenever a policy is sucessfully removed. Reported-by: Ondrej Moris Signed-off-by: Paul Moore Signed-off-by: David S.
