e634134180885574d1fe7aa162777ba41e7fcd5b is the first bad commit commit e634134180885574d1fe7aa162777ba41e7fcd5b Author: Vladimir Oltean Date: Mon May 27 18:39:54 2024 +0300 net/sched: taprio: make q->picos_per_byte available to fill_sched_entry() In commit b5b73b26b3ca ("taprio: Fix allowing too small intervals"), a comparison of user input against length_to_duration(q, ETH_ZLEN) was introduced, to avoid RCU stalls due to frequent hrtimers. The implementation of length_to_duration() depends on q->picos_per_byte being set for the link speed. The blamed commit in the Fixes: tag has moved this too late, so the checks introduced above are ineffective. The q->picos_per_byte is zero at parse_taprio_schedule() -> parse_sched_list() -> parse_sched_entry() -> fill_sched_entry() time. Move the taprio_set_picos_per_byte() call as one of the first things in taprio_change(), before the bulk of the netlink attribute parsing is done. That's because it is needed there. Add a selftest to make sure the issue doesn't get reintroduced.
