In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: QOS: Refactor TC_HTB_LEAF_DEL_LAST callback This patch addresses below issues,
- Active traffic on the leaf node must be stopped before its send queue is reassigned to the parent. This patch resolves the issue by marking the node as 'Inner'.
- During a system reboot, the interface receives TC_HTB_LEAF_DEL and TC_HTB_LEAF_DEL_LAST callbacks to delete its HTB queues. In the case of TC_HTB_LEAF_DEL_LAST, although the same send queue is reassigned to the parent, the current logic still attempts to update the real number of queues, leadning to below warnings New queues can't be registered after device unregistration. WARNING: CPU: 0 PID: 6475 at net/core/net-sysfs.c:1714 netdev_queue_update_kobjects+0x1e4/0x200
Отчет
A flaw was found in the Marvell octeontx2-pf driver when handling HTB queue deletion during system shutdown or reconfiguration. Specifically, when processing the TC_HTB_LEAF_DEL_LAST callback, the send queue may be reassigned to the parent class before active traffic is stopped, or the real number of TX queues may be incorrectly updated after device unregistration.
