Details

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,

  1. 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'.

  2. 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.
