From f307170d6e591a48529425b1ed6ca835790995a9 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 19 Jun 2015 17:23:37 -0500 Subject: [PATCH] netfilter: nf_queue: Don't recompute the hook_list head If someone sends packets from one of the netdevice ingress hooks to the a userspace queue, and then userspace later accepts the packet, the netfilter code can enter an infinite loop as the list head will never be found. Pass in the saved list_head to avoid this. Signed-off-by: "Eric W.
