Prior = to FreeBSD 12.2, bsd_to_linux_sockaddr() didn't check the value of msg.msg_nam= elen (as len). Now it does, if (len < 2 || len > UCHAR_MAX) return (EINVAL); I am currently working around this with, --- linux_socket.c +++ linux_socket.c @@ -926,10 +926,10 @@ goto out; if (PTRIN(args->from) !=3D NULL) { - error =3D bsd_to_linux_sockaddr(sa, &lsa, msg.msg_namelen); + error =3D bsd_to_linux_sockaddr(sa, &lsa, fromlen); if (error =3D=3D 0) error =3D copyout(lsa, PTRIN(args->from), - msg.msg_namelen); + fromlen); free(lsa, M_SONAME); } --=20 You are receiving this mail because: You are the assignee for the bug.=
