Subject: [PATCH net 0/2] Netfilter fixes for net
Date: Wed, 25 Oct 2023 12:08:17 +0200	[thread overview]
Message-ID: <20231025100819.2664-1-pablo@netfilter.org> (raw)

Hi,

This patch contains two late Netfilter's flowtable fixes for net:

1) Flowtable GC pushes back packets to classic path in every GC run,
   ie. every second. This is because NF_FLOW_HW_ESTABLISHED is only
   used by sched/act_ct (never set) and IPS_SEEN_REPLY might be unset
   by the time the flow is offloaded (this status bit is only reliable
   in the sched/act_ct datapath).

2) sched/act_ct logic to push back packets to classic path to reevaluate
   if UDP flow is unidirectional only applies if IPS_HW_OFFLOAD_BIT is
   set on and no hardware offload request is pending to be handled.
   From Vlad Buslov.

These two patches fixes two problems that were introduced in the
previous 6.5 development cycle.
