[PATCH net v7 0/1] net/sched: act_gate: snapshot parameters with RCU on replace

Posted by Paul Moses 1 month, 1 week ago

This series fixes a schedule lifetime race in `act_gate` between the
control-plane replace path and the running hrtimer callback
(`gate_timer_func`).

Changes since v6:
- revert gate_start_timer()
- added explicit chain_put: label before release_idr:
- kzalloc failure path changed from goto release_idr to goto chain_put
- formatting only: blankline cleanup for readability, no behavior change
