fork1 required its callers to pass a pointer to struct proc * which would be set to the new process (if any). procdesc and racct manipulation also used said pointer. However, the process could have exited prior to do_fork return and be automatically reaped, thus making this a use-after-free. Fix the problem by letting callers indicate whether they want the pid or the struct proc, return the process in stopped state for the latter case. Reviewed by: kib |
