From f7fe25a6f00522791cce38bac552d295339d0c79 Mon Sep 17 00:00:00 2001 From: Antony Antony Date: Fri, 21 Oct 2022 15:42:01 +0200 Subject: xfrm: update x->lastused for every packet x->lastused was only updated for outgoing mobile IPv6 packet. With this fix update it for every, in and out, packet. This is useful to check if the a SA is still in use, or when was the last time an SA was used. lastused time of in SA can used to check IPsec path is functional.
