2016-07-03receive: protect against impossible conditionsJason A. Donenfeld
It should never be the case that skb->head + skb->transport_header - skb->data is greater than 2^16, but in case the kernel network stack borks this at some point in the future, we don't want this to slyly introduce a vulnerability into WireGuard. Further, really smart compilers might be able to make deductions about data_offset, and optimize accordingly. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2016-06-30device init: free wq after padataJason A. Donenfeld
The padata free functions make reference to their parent workqueue, so it's important that we wait to free the workqueue after the padata. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2016-06-29device: remove updating of trans_startJason A. Donenfeld
Per http://lists.openwall.net/netdev/2016/05/03/87 dev->trans_start has been removed, and updates are now supposed to be handled with netif_trans_update, which now updates the particular txqueue's trans_start instead. However, netdev_start_xmit already updates this member after calling ndo_start_xmit, so the new netif_trans_update function smartly makes the comment that for drivers that don't use LLTX, it's not neccessary to call netif_trans_update. Except we do use LLTX, so it would seem again that we do need to be calling netif_trans_update. However, glancing at drivers like vxlan and other similar virtual tunnels, this doesn't seem to be the case. I suspect the reason is that we both also set IFF_NO_QUEUE, so we aren't even using a txqueue for updating. Thus, this patch removes updating of trans_start all together. I believe this should be okay for older kernels too. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

With packets hitting multiple cores, a 64bit backtrack was too small. This algorithm increases our backtrack to 1984bits. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
