Instead, it erroneously cleared the skip flag, which\nwould cause the ring to get stuck, as future events won\u0027t match the\nmissed TD which is never removed from the queue until it\u0027s cancelled.\n\nThis buggy logic seems to have been in place substantially unchanged\nsince the 3.x series over 10 years ago, which probably speaks first\nand foremost about relative rarity of this case in normal usage, but\nby the spec I see no reason why it shouldn\u0027t be possible.\n\nAfter d56b0b2ab142, TDs are immediately skipped when handling those\nStopped events. This poses a potential problem in case of Stopped -\nLength Invalid, which occurs either on completed TDs (likely already\ngiven back) or Link and No-Op TRBs. Such event won\u0027t be recognized\nas matching any TD (unless it\u0027s the rare Link TRB inside a TD) and\nwill result in skipping all pending TDs, giving them back possibly\nbefore they are done, risking isoc data loss and maybe UAF by HW.\n\nAs a compromise, don\u0027t skip and don\u0027t clear the skip flag on this\nkind of event. Then the next event will skip missed TDs. A downside\nof not handling Stopped - Length Invalid on a Link inside a TD is\nthat if the TD is cancelled, its actual length will not be updated\nto account for TRBs (silently) completed before the TD was stopped.\n\nI had no luck producing this sequence of completion events so there\nis no compelling demonstration of any resulting disaster. It may be\na very rare, obscure condition. The sole motivation for this patch\nis that if such unlikely event does occur, I\u0027d rather risk reporting\na cancelled partially done isoc frame as empty than gamble with UAF.\n\nThis will be fixed more properly by looking at Stopped event\u0027s TRB\npointer when making skipping decisions, but such rework is unlikely\nto be backported to v6.12, which will stay around for a few years.",

For example, qfq_dump_class may trigger a NULL\ndereference, and qfq_delete_class may cause a use-after-free.\n\nThis patch addresses the issue by:\n\n1.
