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
...

On net.git:

# FAILED: 13 / 16 tests passed.
With this series:

This is a preparation patch for the following patch.
Let's define expected_errno in each test case so that we can add other test
cases easily.

selftest: tcp: Fix address length in bind_wildcard.c.2023-09-13T06:18:04+00:00Kuniyuki Iwashimakuniyu@amazon.com2023-09-11T18:36:58+00:00urn:sha1:0071d15517b4a3d265abc00395beb1138e7236c7
The selftest passes the IPv6 address length for an IPv4 address.
We should pass the correct length.
Note inet_bind_sk() does not check if the size is larger than
sizeof(struct sockaddr_in), so there is no real bug in this
selftest.

selftest: Add test for bind() conflicts.2023-03-15T07:24:10+00:00Kuniyuki Iwashimakuniyu@amazon.com2023-03-12T03:19:04+00:00urn:sha1:13715acf8ab5b32a6d7e42686fceeb66df114185
The test checks if (IPv4, IPv6) address pair properly conflict or not.
* IPv4
* 0.0.0.0
* 127.0.0.1
* IPv6
* ::
* ::1
If the IPv6 address is [::], the second bind() always fails.
