From 2f46e07995734a363608e974a82fd05d5b610750 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Tue, 11 Jan 2011 23:55:51 +0100 Subject: [PATCH] netfilter: ebtables: make broute table work again broute table init hook sets up the "br_should_route_hook" pointer, which then gets called from br_input. commit a386f99025f13b32502fe5dedf223c20d7283826 (bridge: add proper RCU annotation to should_route_hook) introduced a typedef, and then changed this to: br_should_route_hook_t *rhook; [..] rhook = rcu_dereference(br_should_route_hook); if (*rhook(skb)) problem is that "br_should_route_hook" contains the address of the function, so calling *rhook() results in kernel panic.
