The branch main has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=b5e7dbac756afb49c58315c7081737b34a1d2dfd commit b5e7dbac756afb49c58315c7081737b34a1d2dfd Author: Mark Johnston <markj@FreeBSD.org> AuthorDate: 2023-10-16 21:35:07 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2023-10-17 13:12:36 +0000 socket tests: Clean up the MSG_TRUNC regression tests a bit - Fix style. - Move test case-specific code out of the shared function and into the individual test cases. - Remove unneeded setting of SO_REUSEPORT. - Avoid unnecessary copying. - Use ATF_REQUIRE* instead of ATF_CHECK*. The former cause test execution to stop after a failed assertion, which is what we want. - Add a test case for AF_LOCAL/SOCK_SEQPACKET sockets.
