From fd2874b3bbe832e90ac480971a7a8bd736b629b9 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 7 Oct 2015 16:48:32 -0500 Subject: [PATCH] ipv4: Fix ip_local_out_sk by passing the sk into __ip_local_out_sk In the rare case where sk != skb->sk ip_local_out_sk arranges to call dst->output differently if the skb is queued or not. This is a bug. Fix this bug by passing the sk parameter of ip_local_out_sk through from ip_local_out_sk to __ip_local_out_sk (skipping __ip_local_out).
