https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D275920 Kristof Provost <kp@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jhibbits@FreeBSD.org, | |kp@freebsd.org, | |loos@FreeBSD.org, | |mizhka@FreeBSD.org --- Comment #2 from Kristof Provost <kp@freebsd.org> --- That's interesting. The cause is fairly obvious. e6000sw creates struct ifn= ets that don't have an ioctl handler, and that's triggering this crash. The following is probably the best fix, assuming that the ioctl-less e6000sw ifnet is intentional: diff --git a/sys/net/if.c b/sys/net/if.c index 9f44223af0dd..c3c27fbf678f 100644 --- a/sys/net/if.c +++ b/sys/net/if.c @@ -4871,6 +4871,9 @@ if_resolvemulti(if_t ifp, struct sockaddr **srcs, str= uct sockaddr *dst) int if_ioctl(if_t ifp, u_long cmd, void *data) { + if (ifp->if_ioctl =3D=3D NULL) + return (EOPNOTSUPP); + return (ifp->if_ioctl(ifp, cmd, data)); } --=20 You are receiving this mail because: You are the assignee for the bug.=
