:Fine, stick it under DIAGNOSTIC (which isn't dead.) The problem is that there :aren't just 5 places in the kernel that you would need to stick this assert, :you would need it all over the place. But I guess no one else has looked at :all the places that p_ucred is used and thought about how to ensure we don't :use a bogus td_ucred. : : :John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ Don't try to overengineer the problem. Unless you believe there is a serious problem, there is no need to put a check in every single conceivable place an error might occur. Just putting a few safety checks in a few critical places should be sufficient. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
