selftests: forwarding: add shebang for sch_red.sh

2022-09-22T14:33:56+00:00

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: Add test cases for unresolved multicast routes

2022-09-20T15:22:15+00:00

Add IPv4 and IPv6 test cases for unresolved multicast routes, testing
that queued packets are forwarded after installing a matching (S, G)
route.

The test cases can be used to reproduce the bugs fixed in "ipmr: Always
call ip{,6}_mr_forward() from RCU read-side critical section".

selftests: forwarding: Fix failing tests with old libnet

2022-08-11T05:36:14+00:00

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

2022-07-05T09:52:33+00:00

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.
