From 3eed52842b9fd291233c15f65fed34c5d3241183 Mon Sep 17 00:00:00 2001 From: Vlad Buslov Date: Mon, 1 Apr 2019 14:16:59 +0300 Subject: [PATCH] net: sched: don't set tunnel for decap action Action tunnel_key doesn't have a metadata/tunnel for release(decap) action. Drivers do not dereference entry->tunnel pointer for that action type, so this behavior doesn't result in a crash at the moment. However, this needs to be corrected as a preparation for updating hardware offloads API to not rely on rtnl lock, for which flow_action code will copy the tunnel data to temporary buffer to prevent concurrent action overwrite from invalidating/freeing it.
