      signal handling: don't use BUG_ON() for debugging · a382f8fe
      Linus Torvalds authored
      These are indeed "should not happen" situations, but it turns out recent
      changes made the 'task_is_stopped_or_trace()' case trigger (fix for that
      exists, is pending more testing), and the BUG_ON() makes it
      unnecessarily hard to actually debug for no good reason.
      
      It's been that way for a long time, but let's make it clear: BUG_ON() is
      not good for debugging, and should never be used in situations where you
      could just say "this shouldn't happen, but we can continue".
      
      Use WARN_ON_ONCE() instead to make sure it gets logged, and then just
      continue running.  Instead of making the system basically unusuable
      because you crashed the machine while potentially holding some very core
      locks (eg this function is commonly called while holding 'tasklist_lock'
      for writing).

      af_unix: Optimise hash table layout. · cf21b355
      Kuniyuki Iwashima authored
      Commit 6dd4142f ("Merge branch 'af_unix-per-netns-socket-hash'") and
      commit 51bae889 ("af_unix: Put pathname sockets in the global hash
      table.") changed a hash table layout.
      
        Before:
          unix_socket_table [0   - 255] : abstract & pathname sockets
                            [256 - 511] : unnamed sockets
      
        After:
          per-netns table   [0   - 255] : abstract & pathname sockets
                            [256 - 511] : unnamed sockets
          bsd_socket_table  [0   - 255] : pathname sockets (sk_bind_node)
      
      Now, while looking up sockets, we traverse the global table for the
      pathname sockets and the first half of each per-netns hash table for
      abstract sockets, where pathname sockets are also linked.  Thus, the
      more pathname sockets we have, the longer we take to look up abstract
      sockets.  This characteristic has been there before the layout change,
      but we can improve it now.
      
      This patch changes the per-netns hash table's layout so that sockets not
      requiring lookup reside in the first half and do not impact the lookup of
      abstract sockets.
      
          per-netns table   [0   - 255] : pathname & unnamed sockets
                            [256 - 511] : abstract sockets
          bsd_socket_table  [0   - 255] : pathname sockets (sk_bind_node)
      
      We have run a test that bind()s 100,000 abstract/pathname sockets for
      each, bind()s an abstract socket 100,000 times and measures the time
      on __unix_find_socket_byname().  The result shows that the patch makes
      each lookup faster.
      
        Without this patch:
          $ sudo ./funclatency -p 2278 --microseconds __unix_find_socket_byname.isra.44

      Jason A. Donenfeld says:
      
      ====================
      wireguard patches for 5.19-rc6
      
      1) A few small fixups to the selftests, per usual. Of particular note is
         a fix for a test flake that occurred on especially fast systems that
         boot in less than a second.
      
      2) An addition during this cycle of some s390 crypto interacted with the
         way wireguard selects dependencies, resulting in linker errors
         reported by the kernel test robot. So Vladis sent in a patch for
         that, which also required a small preparatory fix moving some Kconfig
         symbols around.

      Select the new implementation of CHACHA20 for S390 when available.
      It is faster than the generic software implementation, but also prevents
      some linker errors in certain situations.

      crypto: s390 - do not depend on CRYPTO_HW for SIMD implementations · b7133757
      Jason A. Donenfeld authored
      Various accelerated software implementation Kconfig values for S390 were
      mistakenly placed into drivers/crypto/Kconfig, even though they're
      mainly just SIMD code and live in arch/s390/crypto/ like usual. This
      gives them the very unusual dependency on CRYPTO_HW, which leads to
      problems elsewhere.
      
      This patch fixes the issue by moving the Kconfig values for non-hardware
      drivers into the usual place in crypto/Kconfig.
