Message-Id: <1443518708-4397-1-git-send-email-michael.rossberg@tu-ilmenau.de> Date: Tue, 29 Sep 2015 11:25:08 +0200 From: Michael Rossberg <michael.rossberg@...ilmenau.de> To: Steffen Klassert <steffen.klassert@...unet.com> Cc: netdev@...r.kernel.org, michael.rossberg@...ilmenau.de Subject: [PATCH 1/1] 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.
