Zefan Li 7e6932300a dlci: validate the net device in dlci_del() ... commit 578a1310f2 upstream. We triggered an oops while running trinity with 3.4 kernel: BUG: unable to handle kernel paging request at 0000000100000d07 IP: [<ffffffffa0109738>] dlci_ioctl+0xd8/0x2d4 [dlci] PGD 640c0d067 PUD 0 Oops: 0000 [#1] PREEMPT SMP CPU 3 ...
