selftests: tc-testing: add action offload selftest for action and filter

2021-12-19T14:08:48Z

Add selftest cases in action police with skip_hw. Add selftest case to validate flags of filter and action. These tests depend on corresponding iproute2 command support. Signed-off-by: Baowen Zheng Signed-off-by: Simon Horman Signed-off-by: David S. Miller

selftests/tc-testings: Be compatible with newer tc output

2021-11-22T12:36:00Z

selftests/tc-testing: match any qdisc type

2021-11-22T12:35:59Z

We should not always presume all kernels use pfifo_fast as the default qdisc. For example, a fq_codel qdisk could have below output: qdisc fq_codel 0: parent 1:4 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 Reported-by: kernel test robot Suggested-by: Peilin Ye Signed-off-by: Li Zhijian Signed-off-by: David S.

tc-testing: Add control-plane selftests for sch_mq

2021-08-04T11:42:27Z

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

2021-07-28T12:19:32Z

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

net/sched: act_vlan: Test priority 0 modification

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

2021-05-24T00:16:09Z

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.
