Subject: [PATCH 2/2] mac80211: Fix dangling pointer in ieee80211_xmit
Date: Wed, 8 Sep 2010 16:34:32 -0700 [thread overview]
Message-ID: <1283988872-44843-3-git-send-email-steve@cozybit.com> (raw)
In-Reply-To: <1283988872-44843-1-git-send-email-steve@cozybit.com>
hdr pointer is left dangling after call to ieee80211_skb_resize. This
can cause guards around mesh path selection to fail.
