2022-09-28T09:32:21Z

[ Upstream commit 83e4b196838d90799a8879e5054a3beecf9ed256 ] RHEL/Fedora RPM build checks are stricter, and complain when executable files don't have a shebang line, e.g. *** WARNING: ./kselftests/net/forwarding/sch_red.sh is executable but has no shebang, removing executable bit Fix it by adding shebang line.

selftests: forwarding: Fix failing tests with old libnet

2022-08-25T09:45:17Z

commit 8bcfb4ae4d970b9a9724ddfbac26c387934e0e94 upstream. The custom multipath hash tests use mausezahn in order to test how changes in various packet fields affect the packet distribution across the available nexthops. The tool uses the libnet library for various low-level packet construction and injection. The library started using the "SO_BINDTODEVICE" socket option for IPv6 sockets in version 1.1.6 and for IPv4 sockets in version 1.2. When the option is not set, packets are not routed according to the table associated with the VRF master device and tests fail. Fix this by prefixing the command with "ip vrf exec", which will cause the route lookup to occur in the VRF routing table. This makes the tests pass regardless of the libnet library version.

selftests: forwarding: fix learning_test when h1 supports IFF_UNICAST_FLT

2022-07-05T09:52:33Z

The first host interface has by default no interest in receiving packets MAC DA de:ad:be:ef:13:37, so it might drop them before they hit the tc filter and this might confuse the selftest. Enable promiscuous mode such that the filter properly counts received packets.

selftests: forwarding: fix flood_unicast_test when h2 supports IFF_UNICAST_FLT

2022-07-05T09:52:33Z

As mentioned in the blamed commit, flood_unicast_test() works by checking the match count on a tc filter placed on the receiving interface. But the second host interface (host2_if) has no interest in receiving a packet with MAC DA de:ad:be:ef:13:37, so its RX filter drops it even before the ingress tc filter gets to be executed. So we will incorrectly get the message "Packet was not flooded when should", when in fact, the packet was flooded as expected but dropped due to an unrelated reason, at some other layer on the receiving side. Force h2 to accept this packet by temporarily placing it in promiscuous mode. Alternatively we could either deliver to its MAC address or use tcpdump_start, but this has the fewest complications. This fixes the "flooding" test from bridge_vlan_aware.sh and bridge_vlan_unaware.sh, which calls flood_test from the lib.

selftests: forwarding: tc_actions: allow mirred egress test to run on non-offloaded h2

2022-05-11T22:12:23Z

The host interfaces $h1 and $h2 don't have to be switchdev interfaces, but due to the fact that we pass $tcflags which may have the value of "skip_sw", we force $h2 to offload a drop rule for dst_ip, something which it may not be able to do. The selftest only wants to verify the hit count of this rule as a means of figuring out whether the packet was received, so remove the $tcflags for it and let it be done in software.
