Hmm. This could be my bug due to mixing up a -stable and a -current
patch. I modified accept() to reject negative sockaddr name lengths, but
it looks like I botched the return path:
if (uap->name) {
error = copyin(uap->anamelen, &namelen, sizeof (namelen));
if(error)
goto done2;
if (namelen < 0)
return (EINVAL);
}
Try turning that 'return (EINVAL);' into a 'goto done2;' and see if that
helps.
