John Baldwin 39092e79ed Don't allow userland to set hardware watch points on kernel memory at all. ... Previously, we tried to allow this only for root. However, we were calling suser() on the *target* process rather than the current process. This means that if you can ptrace() a process running as root you can set a hardware watch point in the kernel. In practice I think you probably have to be root in order to pass the p_candebug() checks in ptrace() to attach to a process running as root anyway. Rather than fix the suser(), I just axed the entire idea, as I can't think of any good reason _at all_ for userland to set hardware watch points for KVM. MFC after: 3 days Also thinks hardware watch points on KVM from userland are bad: bde, rwatson		2006-03-14 16:13:55 +00:00
