Merge branch 'tcp-fix-bind-regression-and-more-tests'
Kuniyuki Iwashima says: ==================== tcp: Fix bind() regression and more tests. 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 v1: https://lore.kernel.org/netdev/20240325181923.48769-1-kuniyu@amazon.com/ ==================== Link: https://lore.kernel.org/r/20240326204251.51301-1-kuniyu@amazon.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
