Mingshuai Ren reports: When a new chain is added by using tc, one soft lockup alarm will be generated after delete the prio 0 filter of the chain. To reproduce the problem, perform the following steps: (1) tc qdisc add dev eth0 root handle 1: htb default 1 (2) tc chain add dev eth0 (3) tc filter del dev eth0 chain 0 parent 1: prio 0 (4) tc filter add dev eth0 chain 0 parent 1: Fix the issue by accounting for additional reference to chains that are explicitly created by RTM_NEWCHAIN message as opposed to implicitly by RTM_NEWTFILTER message. Fixes: 726d061286ce ("net: sched: prevent insertion of new classifiers during chain flush") Reported-by: Mingshuai Ren <renmingshuai@huawei.com> Closes: https://lore.kernel.org/lkml/87legswvi3.fsf@nvidia.com/T/ Signed-off-by: Vlad Buslov <vladbu@nvidia.com> Link: https://lore.kernel.org/r/20230612093426.2867183-1-vladbu@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
