From a12eec740dc6d0c533fb7d83a0a54de6d3abb17c Mon Sep 17 00:00:00 2001 From: Isaac Dunham Date: Wed, 5 Aug 2015 21:33:43 -0500 Subject: reboot: signal init, add -f option to call reboot(); init: use SIGINT, use xsignal() Now that oneit supports the same signals as our "sysv"-init for shutdown, make reboot et al. signal pid 1 with the appropriate signal. Of these signals, only SIGINT works with sysvinit 2.88, causing a reboot. The others are only supported in Busybox init. Also, make init accept SIGINT and use xsignal(). --- toys/other/reboot.c | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) (limited to 'toys/other/reboot.c') diff --git a/toys/other/reboot.c b/toys/other/reboot.c index a1358886..9193ba4e 100644 --- a/toys/other/reboot.c +++ b/toys/other/reboot.c @@ -2,7 +2,7 @@ * * Copyright 2013 Elie De Brauwer -USE_REBOOT(NEWTOY(reboot, "n", TOYFLAG_SBIN|TOYFLAG_NEEDROOT)) +USE_REBOOT(NEWTOY(reboot, "fn", TOYFLAG_SBIN|TOYFLAG_NEEDROOT)) USE_REBOOT(OLDTOY(halt, reboot, TOYFLAG_SBIN|TOYFLAG_NEEDROOT)) USE_REBOOT(OLDTOY(poweroff, reboot, TOYFLAG_SBIN|TOYFLAG_NEEDROOT)) @@ -10,10 +10,11 @@ config REBOOT bool "reboot" default y help - usage: reboot/halt/poweroff [-n] + usage: reboot/halt/poweroff [-fn] Restart, halt or powerdown the system. + -f Don't signal init -n Don't sync before stopping the system. */ @@ -24,8 +25,12 @@ config REBOOT void reboot_main(void) { int types[] = {RB_AUTOBOOT, RB_HALT_SYSTEM, RB_POWER_OFF}; + int sigs[] = {SIGINT, SIGUSR1, SIGUSR2}; if (!(toys.optflags & FLAG_n)) sync(); - toys.exitval = reboot(types[stridx("hp", *toys.which->name)+1]); + if (toys.optflags & FLAG_f) + toys.exitval = reboot(types[stridx("hp", *toys.which->name)+1]); + else + toys.exitval = kill(1, sigs[stridx("hp", *toys.which->name)+1]); } -- cgit v1.2.3
