Andreas Kling	2a65f0ee4f	strace: Allow "strace command" to trace a process from start to finish. ... Tracing a specific pid is now done via "strace -p PID". To ensure we don't miss any syscalls, we fork and have the child immediately SIGSTOP itself. Then when the parent has set up the systrace() fd, we send SIGCONT to the child which then execs the command. :^)	2019-05-02 15:51:39 +02:00
Andreas Kling	5c68929aa1	Kernel: Add a systrace() syscall and implement /bin/strace using it. ... Calling systrace(pid) gives you a file descriptor with a stream of the syscalls made by a peer process. The process must be owned by the same UID who calls systrace(). :^)	2019-04-22 18:44:45 +02:00
