====================
wireguard fixes for 5.6-rc1

Here are fixes for WireGuard before 5.6-rc1 is tagged. It includes:

1) A fix for a UaF (caused by kmalloc failing during a very small
   allocation) that syzkaller found, from Eric Dumazet.

2) A fix for a deadlock that syzkaller found, along with an additional
   selftest to ensure that the bug fix remains correct, from me.

3) Two little fixes/cleanups to the selftests from Krzysztof Kozlowski
   and me.
