2022-02-07ipv4: Stop taking ECN bits into account in fib4-rulesGuillaume Nault1-1/+29
Use the new dscp_t type to replace the tos field of struct fib4_rule, so that fib4-rules consistently ignore ECN bits. Before this patch, fib4-rules did accept rules with the high order ECN bit set (but not the low order one). Also, it relied on its callers masking the ECN bits of ->flowi4_tos to prevent those from influencing the result. This was brittle and a few call paths still do the lookup without masking the ECN bits first. After this patch fib4-rules only compare the DSCP bits. ECN can't influence the result anymore, even if the caller didn't mask these bits. Also, fib4-rules now must have both ECN bits cleared or they will be rejected.

2022-02-07ipv6: Define dscp_t and stop taking ECN bits into account in fib6-rulesGuillaume Nault1-1/+29
Define a dscp_t type and its appropriate helpers that ensure ECN bits are not taken into account when handling DSCP. Use this new type to replace the tclass field of struct fib6_rule, so that fib6-rules don't get influenced by ECN bits anymore. Before this patch, fib6-rules didn't make any distinction between the DSCP and ECN bits. Therefore, rules specifying a DSCP (tos or dsfield options in iproute2) stopped working as soon a packets had at least one of its ECN bits set (as a work around one could create four rules for each DSCP value to match, one for each possible ECN value). After this patch fib6-rules only compare the DSCP bits. ECN doesn't influence the result anymore. Also, fib6-rules now must have the ECN bits cleared or they will be rejected.

2022-02-01selftests: fib rule: Don't echo modified sysctlsGuillaume Nault1-3/+3
Run sysctl in quiet mode. Echoing the modified sysctl doesn't bring any useful information. Signed-off-by: Guillaume Nault <gnault@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-02-01selftests: fib rule: Log test descriptionGuillaume Nault1-4/+6
All callers of fib_rule6_test_match_n_redirect() and fib_rule4_test_match_n_redirect() pass a third argument containing a description of the test being run. Instead of ignoring this argument, let's use it for logging instead of printing a truncated version of the command. Signed-off-by: Guillaume Nault <gnault@redhat.com> Signed-off-by: David S.

2022-02-01selftests: fib rule: Drop erroneous TABLE variableGuillaume Nault1-2/+2
The fib_rule6_del_by_pref() and fib_rule4_del_by_pref() functions use an uninitialised $TABLE variable. They should use $RTABLE instead. This doesn't alter the result of the test, as it just makes the grep command less specific (but since the script always uses the same table number, that doesn't really matter). Let's fix it anyway and, while there, specify the filtering parameters directly in 'ip -X rule show' to avoid the extra grep command entirely.

2021-08-24selftests/net: Use kselftest skip code for skipped testsPo-Hsu Lin1-2/+5
There are several test cases in the net directory are still using exit 0 or exit 1 when they need to be skipped. Use kselftest framework skip code instead so it can help us to distinguish the return status. Criterion to filter out what should be fixed in net directory: grep -r "exit [01]" -B1 | grep -i skip This change might cause some false-positives if people are running these test scripts directly and only checking their return codes, which will change from 0 to 4. However I think the impact should be small as most of our scripts here are already using this skip code. And there will be no such issue if running them with the kselftest framework.

As all the testing addresses are in the same subnet and egress device == ingress device. We need enable forwarding to get the route entry.
