Steps to reproduce(needs two hosts connected with firewire): while true; do ifconfig fwip0 10.0.0.5 up fwcontrol -r ping -c 10.0.0.3 kldunload if_fwip done There's a chance that the unloading of if_fwip.ko triggers following warning: Warning: memory type fw_com leaked memory on destroy (1 allocations, 64 bytes leaked). commit d79b6b8ec267e7eef6e07cf4245159705e24acd5 (origin/main, origin/HEAD) (cherry picked from commit 25a5bb7318052322190a2880e0e7ef18e06d54bd) --- sys/net/if_fwsubr.c | 1 + 1 file changed, 1 insertion(+) diff --git a/sys/net/if_fwsubr.c b/sys/net/if_fwsubr.c index 61c52a9df3c2..cd796b63f857 100644 --- a/sys/net/if_fwsubr.c +++ b/sys/net/if_fwsubr.c @@ -801,6 +801,7 @@ firewire_ifdetach(struct ifnet *ifp) { bpfdetach(ifp); if_detach(ifp); + NET_EPOCH_DRAIN_CALLBACKS(); } voidhome | help
