The crux of the issue is that hfsc is assuming\nthat checking for cl->qdisc->q.qlen == 0 guarantees that it hasn't inserted\nthe class in the vttree or eltree (which is not true for the netem\nduplicate case).\n\nThis patch checks the n_active class variable to make sure that the code\nwon't insert the class in the vttree or eltree twice, catering for the\nreentrant case.\n\n[1] https://lore.kernel.org/netdev/CAHcdcOm+03OD2j6R0=YHKqmy=VgJ8xEOKuP6c7mSgnp-TEJJbw@mail.gmail.com/\n\ud83d\udccf Published: 2025-05-16T13:01:12.798Z\n\ud83d\udccf Modified: 2025-05-16T13:01:12.798Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/e3e949a39a91d1f829a4890e7dfe9417ac72e4d0\n2. https://git.kernel.org/stable/c/8df7d37d626430035b413b97cee18396b3450bef\n3. https://git.kernel.org/stable/c/6082a87af4c52f58150d40dec1716011d871ac21\n4. https://git.kernel.org/stable/c/2e7093c7a8aba5d4f8809f271488e5babe75e202\n5. https://git.kernel.org/stable/c/ac39fd4a757584d78ed062d4f6fd913f83bd98b5\n6. https://git.kernel.org/stable/c/141d34391abbb315d68556b7c67ad97885407547", "creation_timestamp": "2025-05-16T13:35:49.000000Z"}]}
