From 94623f579ce338b5fa61b5acaa5beb8aa657fb9e Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Mon, 3 Apr 2023 13:54:37 +0200 Subject: netfilter: br_netfilter: fix recent physdev match breakage Recent attempt to ensure PREROUTING hook is executed again when a decrypted ipsec packet received on a bridge passes through the network stack a second time broke the physdev match in INPUT hook. We can't discard the nf_bridge info strct from sabotage_in hook, as this is needed by the physdev match. Keep the struct around and handle this with another conditional instead.
