Prevent wg(4) stuck on peer destruction. While interface going down and output stopped, packets could rest in `if_snd' queue. So the (!ifq_empty(&sc->sc_if.if_snd)) condition will always be true and wg_peer_destroy() will sleep until interface became up and stuck packets transmitted. Check IFF_RUNNING flag within (!ifq_empty(&sc->sc_if.if_snd)) loop in wg_peer_destroy(). If the flag is not set that means interface is down, so drain the `if_snd' queue manually to prevent wg_peer_destroy() stuck. Problem reported and fix tested by Kirill Miazine. ok bluhm@ |
