      x86/csum: clean up `csum_partial' further · a476aae3
      Linus Torvalds authored
      Commit 688eb819 ("x86/csum: Improve performance of `csum_partial`")
      ended up improving the code generation for the IP csum calculations, and
      in particular special-casing the 40-byte case that is a hot case for
      IPv6 headers.
      
      It then had _another_ special case for the 64-byte unrolled loop, which
      did two chains of 32-byte blocks, which allows modern CPU's to improve
      performance by doing the chains in parallel thanks to renaming the carry
      flag.
      
      This just unifies the special cases and combines them into just one
      single helper the 40-byte csum case, and replaces the 64-byte case by a
      80-byte case that just does that single helper twice.  It avoids having
      all these different versions of inline assembly, and actually improved
      performance further in my tests.
      
      There was never anything magical about the 64-byte unrolled case, even
      though it happens to be a common size (and typically is the cacheline
      size).

      x86/csum: Remove unnecessary odd handling · 5d4acb62
      Noah Goldstein authored
      The special case for odd aligned buffers is unnecessary and mostly
      just adds overhead. Aligned buffers is the expectations, and even for
      unaligned buffer, the only case that was helped is if the buffer was
      1-byte from word aligned which is ~1/7 of the cases. Overall it seems
      highly unlikely to be worth to extra branch.
      
      It was left in the previous perf improvement patch because I was
      erroneously comparing the exact output of `csum_partial(...)`, but
      really we only need `csum_fold(csum_partial(...))` to match so its
      safe to remove.
      
      All csum kunit tests pass.

      net/tcp: Only produce AO/MD5 logs if there are any keys · 4c8530dc
      Dmitry Safonov authored
      User won't care about inproper hash options in the TCP header if they
      don't use neither TCP-AO nor TCP-MD5. Yet, those logs can add up in
      syslog, while not being a real concern to the host admin:
      > kernel: TCP: TCP segment has incorrect auth options set for XX.20.239.12.54681->XX.XX.90.103.80 [S]
      
      Keep silent and avoid logging when there aren't any keys in the system.
      
      Side-note: I also defined static_branch_tcp_*() helpers to avoid more
      ifdeffery, going to remove more ifdeffery further with their help.
