Fix a bug introduced in 69cce1d140 ("net: Abstract dst->neighbour accesses behind helpers.") where we might dereference skb_dst(skb) even if it is NULL, which causes: [ 240.944030] BUG: unable to handle kernel NULL pointer dereference at 0000000000000040 [ 240.948007] IP: [<ffffffffa0366ce9>] ipoib_start_xmit+0x39/0x280 [ib_ipoib] [...] [ 240.948007] Call Trace: [ 240.948007] <IRQ> [ 240.948007] [<ffffffff812cd5e0>] dev_hard_start_xmit+0x2a0/0x590 [ 240.948007] [<ffffffff8131f680>] ? arp_create+0x70/0x200 [ 240.948007] [<ffffffff812e8e1f>] sch_direct_xmit+0xef/0x1c0 Addresses: https://bugzilla.kernel.org/show_bug.cgi?id=41212 Signed-off-by: Bernd Schubert <bernd.schubert@itwm.fraunhofer.de> Signed-off-by: Roland Dreier <roland@purestorage.com>		2011-08-16 10:19:20 -07:00
