From d70063c4634af060a5387337b7632f6334ca3458 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 2 Sep 2005 12:18:03 -0700 Subject: [PATCH] [ATM]: Fix dereference of uninitialized pointer in zatm Fixing breakage from [NET]: Kill skb->list - original was assign vcc do a bunch of stuff using ZATM_VCC(vcc)->pool as common subexpression Now we do int pos = ZATM_VCC(vcc)->pool; assign vcc do a bunch of stuff even though vcc is not even initialized when we enter that block...
