[PATCH v7 1/2] signal: add pidfd_send_signal() syscall

2019-01-02 Thread Christian Brauner
The kill() syscall operates on process identifiers (pid). After a process has exited its pid can be reused by another process. If a caller sends a signal to a reused pid it will end up signaling the wrong process. This issue has often surfaced and there has been a push to address this problem [1].
