The branch stable/12 has been updated by kp: URL: https://cgit.FreeBSD.org/src/commit/?id=086f8d605606aa0f3d8092f5757558cadd5e4233 commit 086f8d605606aa0f3d8092f5757558cadd5e4233 Author: Tom Jones <thj@FreeBSD.org> AuthorDate: 2019-08-05 11:47:34 +0000 Commit: Kristof Provost <kp@FreeBSD.org> CommitDate: 2021-09-14 08:26:33 +0000 Add common firewall test suite Add a common test suite for the firewalls included in the base system. The test suite allows common test infrastructure to test pf, ipfw and ipf firewalls from test files containing the setup for all three firewalls. Add the pass block test for pf, ipfw and ipf. The pass block test checks the allow/deny functionality of the firewalls tested. Submitted by: Ahsan Barkati Sponsored by: Google, Inc.
