From 53f88ed85bdd194b8a30605a264692b28a3ee665 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Wed, 14 Aug 2024 14:10:04 +0300 Subject: [PATCH] selftests: fib_rule_tests: Add negative connect tests The fib_rule{4,6}_connect tests verify that locally generated traffic from a socket that specifies a DS Field using the IP_TOS / IPV6_TCLASS socket options is correctly redirected using a FIB rule that matches on the given DS Field. Add negative tests to verify that the FIB rule is not hit when the socket specifies a DS Field that differs from the one used by the FIB rule.
