selftest: tcp: Add v4-mapped-v6 cases in bind_wildcard.c.
We add these 8 test cases in bind_wildcard.c to check bind() conflicts. 1st bind() 2nd bind() --------- --------- 0.0.0.0 ::FFFF:0.0.0.0 ::FFFF:0.0.0.0 0.0.0.0 0.0.0.0 ::FFFF:127.0.0.1 ::FFFF:127.0.0.1 0.0.0.0 127.0.0.1 ::FFFF:0.0.0.0 ::FFFF:0.0.0.0 127.0.0.1 127.0.0.1 ::FFFF:127.0.0.1 ::FFFF:127.0.0.1 127.0.0.1 All test passed without bhash2 and with bhash2 and this series. Before bhash2: $ uname -r 6.0.0-rc1-00393-g0bf73255d3a3 $ ./bind_wildcard ... # PASSED: 16 / 16 tests passed. Just after bhash2: $ uname -r 6.0.0-rc1-00394-g28044fc1d495 $ ./bind_wildcard ... ok 15 bind_wildcard.v4_local_v6_v4mapped_local.v4_v6 not ok 16 bind_wildcard.v4_local_v6_v4mapped_local.v6_v4 # FAILED: 15 / 16 tests passed. On net.git: $ ./bind_wildcard ... not ok 14 bind_wildcard.v4_local_v6_v4mapped_any.v6_v4 not ok 16 bind_wildcard.v4_local_v6_v4mapped_local.v6_v4 # FAILED: 13 / 16 tests passed. With this series: $ ./bind_wildcard ... # PASSED: 16 / 16 tests passed. Signed-off-by: Kuniyuki Iwashima <kuniyu@amazon.com> Signed-off-by: David S. Miller <davem@davemloft.net>
