The\nsame concurrency lets throttled multiplex frames from different\ninterfaces clobber the single rx_ifindex/rx_stamp fields shared by\nthe op.\n\nAdd op->if_detected to track the first interface that delivers a\nmatching frame while a timeout/throttle timer is configured, and\nreject frames from any other interface for that op. The claim is\ndecided in bcm_rx_handler() before hrtimer_cancel() touches\nop->timer, so a rejected frame can never disturb the claimed\ninterface's watchdog. RTR-mode ops are excluded via RX_RTR_FRAME,\nindependent of kt_ival1/kt_ival2, since those may briefly hold a\nstale value from an earlier non-RTR configuration.\n\nThe claim is released in bcm_notify() on NETDEV_UNREGISTER and in\nbcm_rx_setup() when SETTIMER reconfigures the timer values.\n\nA (re-)claim is only possible on CAN devices in NETREG_REGISTERED\ndev->reg_state to cover the release in bcm_notify() where reg_state\nbecomes NETREG_UNREGISTERING until synchronize_net().","state":0,"publishedAt":"2026-08-15T05:52:55.524+00:00","modifiedAt":"2026-10-16T18:44:56.703+00:00","affected":[{"ecosystem":"Vendor
