Revision c9a82bec02c339cdda99b37c5e62b3b71fc4209c authored by Vlad Buslov on 12 June 2023, 09:34:26 UTC, committed by Jakub Kicinski on 15 June 2023, 06:03:16 UTC
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.
