[PATCH net 00/10] wireguard/siphash patches for 5.16-rc6

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

Hi Dave/Jakub,

Here's quite a largeish set of stable patches I've had queued up and
testing for a number of months now:

  - Patch (1) squelches a sparse warning by fixing an annotation.
  - Patches (2), (3), and (5) are minor improvements and fixes to the
    test suite.
  - Patch (4) is part of a tree-wide cleanup to have module-specific
    init and exit functions.
  - Patch (6) fixes a an issue with dangling dst references, by having a
    function to release references immediately rather than deferring,
    and adds an associated test case to prevent this from regressing.
  - Patches (7) and (8) help mitigate somewhat a potential DoS on the
    ingress path due to the use of skb_list's locking hitting contention
    on multiple cores by switching to using a ring buffer and dropping
    packets on contention rather than locking up another core spinning.
  - Patch (9) switches kvzalloc to kvcalloc for better form.
  - Patch (10) fixes alignment traps in siphash with clang-13 (and maybe
    other compilers) on armv6, by switching to using the unaligned
    functions by default instead of the aligned functions by default.

Thanks,
Jason
