H A D | ip_dummynet.h | diff 112710 Thu Mar 27 12:56:36 MST 2003 maxim o Protect set_fs_param() by splimp(9). Quote from kern/37573: There is an obvious race in netinet/ip_dummynet.c:config_pipe(). Interrupts are not blocked when changing the params of an existing pipe. The specific crash observed: ... -> config_pipe -> set_fs_parms -> config_red malloc a new w_q_lookup table but take an interrupt before intializing it, interrupt handler does: ... -> dummynet_io -> red_drops red_drops dereferences the uninitialized (zeroed) w_q_lookup table. o Flush accumulated credits for idle pipes. o Flush accumulated credits when change pipe characteristics. o Change dn_flow_queue.numbytes type to unsigned long. Overlapping dn_flow_queue->numbytes in ready_event() leads to numbytes becomes negative and SET_TICKS() macro returns a very big value. heap_insert() overlaps dn_key again and inserts a queue to a ready heap with a sched_time points to the past. That leads to an "infinity" loop.
