In the Linux kernel, the following vulnerability has been resolved:net/sched: taprio: extend minimum interval restriction to entire cycle tooIt is possible for syzbot to side-step the restriction imposed by theblamed commit in the Fixes: tag, because the taprio UAPI permits acycle-time different from (and potentially shorter than) the sum ofentry intervals.We need one more restriction, which is that the cycle time itself mustbe larger than N * ETH_ZLEN bit times, where N is the number of scheduleentries. This restriction needs to apply regardless of whether the cycletime came from the user or was the implicit, auto-calculated value, sowe move the existing cycle == 0 check outside the if (!new->cycle_time) branch. This way covers both conditions and scenarios.Add a selftest which illustrates the issue triggered by syzbot.

This restriction needs to apply regardless of whether the cycletime came from the user or was the implicit, auto-calculated value, sowe move the existing cycle == 0 check outside the if (!new->cycle_time) branch. This way covers both conditions and scenarios.Add a selftest which illustrates the issue triggered by syzbot.
In the Linux kernel, the following vulnerability has been resolved:net/sched: taprio: extend minimum interval restriction to entire cycle tooIt is possible for syzbot to side-step the restriction imposed by theblamed commit in the Fixes: tag, because the taprio UAPI permits acycle-time different from (and potentially shorter than) the sum ofentry intervals.We need one more restriction, which is that the cycle time itself mustbe larger than N * ETH_ZLEN bit times, where N is the number of scheduleentries.
