2019-02-14Don't allow writing or reading to TTY unless process group is in foreground.Nicolas Lacasse
If a background process tries to read from a TTY, linux sends it a SIGTTIN unless the signal is blocked or ignored, or the process group is an orphan, in which case the syscall returns EIO. See drivers/tty/n_tty.c:n_tty_read()=>job_control(). If a background process tries to write a TTY, set the termios, or set the foreground process group, linux then sends a SIGTTOU. If the signal is ignored or blocked, linux allows the write. If the process group is an orphan, the syscall returns EIO. See drivers/tty/tty_io.c:tty_check_change().
