This is a note to let you know that I have just added a patch titled cfg80211: check wdev->netdev in connection work to the linux-3.8.y-queue branch of the 3.8.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.8.y-queue This patch is scheduled to be released in version 3.8.13.3. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From d070c0a4f8d8d12afa359d06d9edb5639865beef Mon Sep 17 00:00:00 2001 From: Johannes Berg <johannes.berg@intel.com> Date: Thu, 23 May 2013 18:10:21 +0200 Subject: cfg80211: check wdev->netdev in connection work commit c815797663b72e3ac1736f1886538152bc48e4af upstream. If a P2P-Device is present and another virtual interface triggers the connection work, the system crash because it tries to check if the P2P-Device's netdev (which doesn't exist) is up. Skip any wdevs that have no netdev to fix this.
