commit dc9da87bd334906375eb35c3adaceaf0b6b4f2e3 Author: Kristof Provost <[email protected]> AuthorDate: 2023-05-31 19:45:29 +0000 Commit: Kristof Provost <[email protected]> CommitDate: 2023-08-11 12:13:09 +0000 pf tests: test SCTP 'return' Ensure that we send a correct abort message for 'block return' rules. Test this by validating that nc doesn't sit around waiting for a connection. It should give up immediately when it receives the abort.
