From 1bf40954cf232a043a49623cf251f787c1871e64 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 16 Dec 2007 14:04:02 -0800 Subject: [PATCH] [PACKET]: Fix /proc/net/packet crash due to bogus private pointer The seq_open_net patch changed the meaning of seq->private. Unfortunately it missed two spots in AF_PACKET, which still used the old way of dereferencing seq->private, thus causing weird and wonderful crashes when reading /proc/net/packet.
