Message

Kuniyuki Iwashima March 25, 2024, 6:19 p.m. UTC

bhash2 has not been well tested for IPV6_V6ONLY option.

This series fixes two regression around IPV6_V6ONLY, one of which
has been there since bhash2 introduction, and another is introduced
by a recent change.

Also, this series adds as many tests as possible to catch regression
easily.  The baseline is 28044fc1d495~ which is pre-bhash2 commit.

 Tested on 28044fc1d495~:
  # PASSED: 132 / 132 tests passed.
  # Totals: pass:132 fail:0 xfail:0 xpass:0 skip:0 error:0

 net.git:
  # FAILED: 125 / 132 tests passed.
  # Totals: pass:125 fail:7 xfail:0 xpass:0 skip:0 error:0

 With this series:
  # PASSED: 132 / 132 tests passed.
  # Totals: pass:132 fail:0 xfail:0 xpass:0 skip:0 error:0
