From 4e077237cfb6ab13701d504060d3ae248b191e6e Mon Sep 17 00:00:00 2001 From: Michael Rossberg Date: Tue, 29 Sep 2015 11:25:08 +0200 Subject: xfrm: Fix state threshold configuration from userspace Allow to change the replay threshold (XFRMA_REPLAY_THRESH) and expiry timer (XFRMA_ETIMER_THRESH) of a state without having to set other attributes like replay counter and byte lifetime. Changing these other values while traffic flows will break the state.
