Modified Files: src/sys/kern [netbsd-9]: sys_ptrace_common.c src/sys/sys [netbsd-9]: ptrace.h Log Message: Pull up following revision(s) (requested by kamil in ticket #325): sys/sys/ptrace.h: revision 1.66 sys/kern/sys_ptrace_common.c: revision 1.66 Introduce new ptrace(2) operation PT_STOP It works like: - kill(SIGSTOP) for unstopped tracee - ptrace(PT_CONTINUE,SIGSTOP) for stopped tracee The child will be stopped and always possible to be waited (with wait(2) like calls). For stopped traccee kill(SIGSTOP) has no effect. PT_CONTINUE+SIGSTOP cannot be used on an unstopped process (EBUSY). This operation is modeled after PT_KILL that is similar for the SIGKILL call. While there, allow PT_KILL on unstopped traced child. This operation is useful in an abnormal exit of a debugger from a signal handler, usually followed by waitpid(2) and ptrace(PT_DETACH).
