2017-10-02noise: use spinlock for rotating keysJason A. Donenfeld
This should only really be contended in extremely exceptional cases, so changing from a mutex to a spinlock is likely fine. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-09-24tools: use key_is_zero for comparing to zerosJason A. Donenfeld
Maybe an attacker on the system could use the infoleak in /proc to gauge how long a wg(8) process takes to complete and determine the number of leading zeros. This is somewhat ridiculous, but it's possible somebody somewhere might at somepoint care in the future, so alright. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-09-19send: don't take uninitialized lockJason A. Donenfeld
Packets is a local, which means we need to use the functions that don't take a spinlock, since otherwise we'll be using a spinlock in an undefined state. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-09-19receive: use netif_receive_skb instead of netif_rxJason A. Donenfeld
netif_rx queues things up to a per-cpu backlog, whereas netif_receive_skb immediately delivers the packet to the underlying network device and mostly never fails. In the event where decrypting packets is actually happening faster than the networking subsystem receive them -- like with 65k packets with UDPv6 in `make test-qemu` -- then this backlog fills up and we wind up dropping some packets. This is fine and not all together terrible, but it does raise the question of why we bothered spending CPU cycles decrypting those packets if they were just going to be dropped anyway. So, moving from netif_rx to netif_receive_skb means that whatever time netif_receive_skb needs winds up slowing down the dequeuing of decryption packets, which in turn means the decryption receive queue fills up sooner, so that we drop packets before decryption, rather than after, thus saving precious CPU cycles. Potential downsides of this include not keeping the cache hot, or not inundating the network subsystem with as many packets per second as possible, but in preliminary benchmarks, no difference has yet been observed.

2017-09-18queue: entirely rework parallel systemJason A. Donenfeld
This removes our dependency on padata and moves to a different mode of multiprocessing that is more efficient. This began as Samuel Holland's GSoC project and was gradually reworked/redesigned/rebased into this present commit, which is a combination of his initial contribution and my subsequent rewriting and redesigning.
