[PATCH v3 31/36] selftests/tcp-ao: Add TCP-AO + TCP-MD5 + no sign listen socket tests

Dmitry Safonov
2022-10-27T20:52:55Z

The test plan was (most of tests have all 3 client types):
1. TCP-AO listen (INADDR_ANY)
2. TCP-MD5 listen (INADDR_ANY)
3. non-signed listen (INADDR_ANY)
4. TCP-AO + TCP-MD5 listen (prefix)
5. TCP-AO subprefix add failure [checked in setsockopt-closed.c]
6. TCP-AO out of prefix connect [checked in connect-deny.c]
7. TCP-AO + TCP-MD5 on connect()
8. TCP-AO intersect with TCP-MD5 failure
9. Established TCP-AO: add TCP-MD5 key
10. Established TCP-MD5: add TCP-AO key
11. Established non-signed: add TCP-AO key

Output produced:
1..42
