This tc action allows you to retrieve the connection tracking mark This action has been used heavily by openwrt for a few years now. There are known limitations currently: doesn't work for initial packets, since we only query the ct table. Fine given use case is for returning packets no implicit defrag. frags should be rare so fix later.. won't work for more complex tasks, e.g. lookup of other extensions since we have no means to store results we still have a 2nd lookup later on via normal conntrack path. This shouldn't break anything though since skb->nfct isn't altered. V2: remove unnecessary braces (Jiri) change the action identifier to 14 (Jiri) Fix some stylistic issues caught by checkpatch V3: Move module params to bottom (Cong) Get rid of tcf_hashinfo_init and friends and conform to newer API (Cong) Acked-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S.
