The failure occurs because TBF sometimes peeks at\npackets in the child qdisc without actually dequeuing them when tokens are\nunavailable.\n\nThis peek operation creates a discrepancy between the parent and child qdisc\nqueue length counters. When TBF later receives a high-priority packet,\nSKBPRIO's queue length may show a different value than what's reflected in its\ninternal priority queue tracking, triggering the assertion.\n\nThe fix removes this overly strict assertions in SKBPRIO, they are not\nnecessary at all.\n\ud83d\udccf Published: 2025-04-18T07:01:34.564Z\n\ud83d\udccf Modified: 2025-04-18T07:01:34.564Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/7abc8318ce0712182bf0783dcfdd9a6a8331160e\n2. https://git.kernel.org/stable/c/1284733bab736e598341f1d3f3b94e2a322864a8\n3. https://git.kernel.org/stable/c/32ee79682315e6d3c99947b3f38b078a09a66919\n4. https://git.kernel.org/stable/c/1dcc144c322a8d526b791135604c0663f1af9d85\n5. https://git.kernel.org/stable/c/864ca690ff135078d374bd565b9872f161c614bc\n6. https://git.kernel.org/stable/c/2f35b7673a3aa3d09b3eb05811669622ebaa98ca\n7. https://git.kernel.org/stable/c/2286770b07cb5268c03d11274b8efd43dff0d380\n8. https://git.kernel.org/stable/c/034b293bf17c124fec0f0e663f81203b00aa7a50\n9. https://git.kernel.org/stable/c/ce8fe975fd99b49c29c42e50f2441ba53112b2e8", "creation_timestamp": "2025-04-18T07:59:13.000000Z"}
