The test case shown in [1] triggers the kernel to access the null pointer. Therefore, add related test cases to mq. The test results are as follows: ./tdc.py -e 0531 1..1 ok 1 0531 - Replace mq with invalid parent ID ./tdc.py -c mq 1..8 ok 1 ce7d - Add mq Qdisc to multi-queue device (4 queues) ok 2 2f82 - Add mq Qdisc to multi-queue device (256 queues) ok 3 c525 - Add duplicate mq Qdisc ok 4 128a - Delete nonexistent mq Qdisc ok 5 03a9 - Delete mq Qdisc twice ok 6 be0f - Add mq Qdisc to single-queue device ok 7 1023 - Show mq class ok 8 0531 - Replace mq with invalid parent ID [1] https://lore.kernel.org/all/20230527093747.3583502-1-shaozhengchao@huawei.com/ Signed-off-by: Zhengchao Shao <shaozhengchao@huawei.com> Reviewed-by: Pedro Tammela <pctammela@mojatatu.com> Link: https://lore.kernel.org/r/20230601012250.52738-1-shaozhengchao@huawei.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
