[PATCH v3 net 0/4] wireguard fixes for 5.6-rc2

["Jason A. Donenfeld" <Jason@zx2c4.com>]

Here are four fixes for wireguard collected since rc1:

1) Some small cleanups to the test suite to help massively parallel
   builds.

2) A change in how we reset our load calculation to avoid a more
   expensive comparison, suggested by Matt Dunwoodie.

3) I've been loading more and more of wireguard's surface into
   syzkaller, trying to get our coverage as complete as possible,
   leading in this case to a fix for mtu=0 devices.

4) A removal of superfluous code, pointed out by Eric Dumazet.

v2 fixes a logical problem in the patch for (3) pointed out by Eric Dumazet. v3
replaces some non-obvious bitmath in (3) with a more obvious expression, and
adds patch (4).

Jason A. Donenfeld (4):
  wireguard: selftests: reduce complexity and fix make races
  wireguard: receive: reset last_under_load to zero
  wireguard: send: account for mtu=0 devices
  wireguard: socket: remove extra call to synchronize_net
