From ec6743a10996d38e0438e5f45f2347ff2f42df0a Mon Sep 17 00:00:00 2001 From: Vlad Buslov Date: Mon, 11 Feb 2019 10:55:43 +0200 Subject: net: sched: track rtnl lock status when validating extensions Actions API is already updated to not rely on rtnl lock for synchronization. However, it need to be provided with rtnl status when called from classifiers API in order to be able to correctly release the lock when loading kernel module. Extend extension validation function with 'rtnl_held' flag which is passed to actions API. Add new 'rtnl_held' parameter to tcf_exts_validate() in cls API. No classifier is currently updated to support unlocked execution, so pass hardcoded 'true' flag parameter value. Signed-off-by: Vlad Buslov Acked-by: Jiri Pirko Signed-off-by: David S.
