Subject: [PATCH v12 nf-next 0/2] conntrack: bridge: add double vlan, pppoe and pppoe-in-q
Date: Tue, 17 Jun 2025 08:58:33 +0200	[thread overview]
Message-ID: <20250617065835.23428-1-ericwouds@gmail.com> (raw)

Conntrack bridge only tracks untagged and 802.1q.

To make the bridge-fastpath experience more similar to the
forward-fastpath experience, add double vlan, pppoe and pppoe-in-q
tagged packets to bridge conntrack and to bridge filter chain.

Changes in v12:

- Only allow tracking this traffic when a conntrack zone is set.
- nf_ct_bridge_pre(): skb pull/push without touching the checksum,
   because the pull is always restored with push.
- nft_do_chain_bridge(): handle the extra header similar to
   nf_ct_bridge_pre(), using pull/push.

Changes in v11:

- nft_do_chain_bridge(): Proper readout of encapsulated proto.
- nft_do_chain_bridge(): Use skb_set_network_header() instead of thoff.
- removed test script, it is now in separate patch.

v10 split from patch-set: bridge-fastpath and related improvements v9
