tc-testing: Add control-plane selftests for sch_mq

2021-08-04T11:42:27+00:00

Recently we added multi-queue support to netdevsim in commit d4861fc6be58 ("netdevsim: Add multi-queue support"); add a few control-plane selftests for sch_mq using this new feature. Use nsPlugin.py to avoid network interface name collisions. Reviewed-by: Cong Wang Signed-off-by: Peilin Ye Signed-off-by: David S. Miller

tc-testing: Add control-plane selftest for skbmod SKBMOD_F_ECN option

2021-07-28T12:19:32+00:00

Recently we added a new option, SKBMOD_F_ECN, to tc-skbmod(8). Add a control-plane selftest for it. Depends on kernel patch "net/sched: act_skbmod: Add SKBMOD_F_ECN option support", as well as iproute2 patch "tc/skbmod: Introduce SKBMOD_F_ECN option".

tc-testing: add test for ct DNAT tuple collision

2021-06-22T17:52:39+00:00

When this test fails, /proc/net/nf_conntrack gets only 1 entry: ipv4 2 tcp 6 119 SYN_SENT src=10.0.0.10 dst=10.0.0.10 sport=5000 dport=10 [UNREPLIED] src=20.0.0.1 dst=10.0.0.10 sport=10 dport=5000 mark=0 secctx=system_u:object_r:unlabeled_t:s0 zone=0 use=2 When it works, it gets 2 entries: ipv4 2 tcp 6 119 SYN_SENT src=10.0.0.10 dst=10.0.0.20 sport=5000 dport=10 [UNREPLIED] src=20.0.0.1 dst=10.0.0.10 sport=10 dport=58203 mark=0 secctx=system_u:object_r:unlabeled_t:s0 zone=0 use=2 ipv4 2 tcp 6 119 SYN_SENT src=10.0.0.10 dst=10.0.0.10 sport=5000 dport=10 [UNREPLIED] src=20.0.0.1 dst=10.0.0.10 sport=10 dport=5000 mark=0 secctx=system_u:object_r:unlabeled_t:s0 zone=0 use=2 The missing entry is because the 2nd packet hits a tuple collusion and the conntrack entry doesn't get allocated.

tc-testing: add support for sending various scapy packets

2021-06-22T17:52:39+00:00

It can be worth sending different scapy packets on a given test, as in the last patch of this series. For that, lets listify the scapy attribute and simply iterate over it. Signed-off-by: Marcelo Ricardo Leitner Signed-off-by: David S. Miller

tc-testing: fix list handling

2021-06-22T17:52:39+00:00

python lists don't have an 'add' method, but 'append'. Fixes: 14e5175e9e04 ("tc-testing: introduce scapyPlugin for basic traffic") Signed-off-by: Marcelo Ricardo Leitner Signed-off-by: David S. Miller

net/sched: act_vlan: Test priority 0 modification

Because explicitly being set, the priority 0 should appear in the output. Signed-off-by: Boris Sukholitko Signed-off-by: David S. Miller

net/sched: act_vlan: No dump for unset priority

Dump vlan priority only if it has been previously set. Fix the tests accordingly. Signed-off-by: Boris Sukholitko Signed-off-by: David S. Miller

net/sched: fq_pie: re-factor fix for fq_pie endless loop

2021-05-24T00:16:09+00:00

the patch that fixed an endless loop in_fq_pie_init() was not considering that 65535 is a valid class id. The correct bugfix for this infinite loop is to change 'idx' to become an u32, like Colin proposed in the past [1]. Fix this as follows: - restore 65536 as maximum possible values of 'flows_cnt' - use u32 'idx' when iterating on 'q->flows' - fix the TDC selftest This reverts commit bb2f930d6dd708469a587dc9ed1efe1ef969c0bf.
