The objective is to cover kernel paths that use the RTO_ONLINK flag in .flowi4_tos. This way we'll be able to safely remove this flag in the future by properly setting .flowi4_scope instead. With these selftests in place, we can make sure this won't introduce regressions. For more context, the final objective is to convert .flowi4_tos to dscp_t, to ensure that ECN bits don't influence route and fib-rule lookups (see commit a410a0cf9885 ("ipv6: Define dscp_t and stop taking ECN bits into account in fib6-rules")). These selftests only cover IPv4, as SO_DONTROUTE has no effect on IPv6 sockets. v2: - Use two different nettest options for setting SO_DONTROUTE either on the server or on the client socket. - Use the above feature to run a single 'nettest -B' instance per test (instead of having two nettest processes for server and client). ==================== Signed-off-by: David S.
