+ Subject: [PATCH] login: use TCSANOW to remove HUPCL
+
+ login(1) code:
+
+ ttt.c_cflag &= ~HUPCL;
+ tcsetattr(0, TCSAFLUSH, &ttt);
+
+ close(STDIN_FILENO);
+ close(STDOUT_FILENO);
+ close(STDERR_FILENO);
+
+ signal(SIGHUP, SIG_IGN); /* so vhangup() wont kill us */
+ vhangup();
+ signal(SIGHUP, SIG_DFL);
+
+ strace :
+
+ ioctl(0, SNDCTL_TMR_CONTINUE or SNDRV_TIMER_IOCTL_GPARAMS or TCSETSF, {B9600 opost isig icanon echo ...}) = 0
+ close(0) = 0
+ close(1) = 0
+ close(2) = 0
+ --- SIGHUP {si_signo=SIGHUP, si_code=SI_KERNEL} ---
+ --- SIGTERM {si_signo=SIGTERM, si_code=SI_USER, si_pid=1, si_uid=0} ---
+ +++ killed by SIGTERM +++
+
+ It seems we get SIGHUP (and SIGTERM from systemd) before vhangup().
+ The problem occur sometimes.
+
+ I guess it's because TCSAFLUSH is not applied immediately, so it would
+ be probably better to use TCSANOW to make the code more robust.
