Subject: [PATCH net v2 0/6] net/sched: Fix packet loops in mirred and netem
Date: Mon, 16 Mar 2026 17:10:46 -0400	[thread overview]
Message-ID: <20260316211052.332383-1-jhs@mojatatu.com> (raw)

We introduce a 2-bit global skb->ttl counter. Patch #1 describes how we put
together those bits. Patches #2 and patch #5 use these bits.
I added Fixes tags to patch #1 in case it is useful for backporting.
Patch #3 and #4 revert William's earlier netem commits. Patch #6 introduces
tdc test cases.

Changes in v2:
Do not reuse skb->from_ingress (which was move skb->cb)

Jamal Hadi Salim (5):
  net: Introduce skb ttl field to track packet loops
  net/sched: Fix ethx:ingress -> ethy:egress -> ethx:ingress mirred loop
  Revert "net/sched: Restrict conditions for adding duplicating netems
    to qdisc tree"
  Revert "selftests/tc-testing: Add tests for restrictions on netem
    duplication"
  net/sched: fix packet loop on netem when duplicate is on

Victor Nogueira (1):
  selftests/tc-testing: Add netem/mirred test cases exercising loops
