From 09812eb764b440651f3ff4cb5d37bd343f800560 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Sun, 22 Dec 2013 22:14:05 +0100 Subject: sd-daemon: introduce sd_watchdog_enabled() for parsing $WATCHDOG_USEC Also, introduce a new environment variable named $WATCHDOG_PID which cotnains the PID of the process that is supposed to send the keep-alive events. This is similar how $LISTEN_FDS and $LISTEN_PID work together, and protects against confusing processes further down the process tree due to inherited environment. --- src/core/service.c | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) (limited to 'src/core/service.c') diff --git a/src/core/service.c b/src/core/service.c index 87eaa29378..4eb3d9e668 100644 --- a/src/core/service.c +++ b/src/core/service.c @@ -1750,7 +1750,7 @@ static int service_spawn( if (r < 0) goto fail; - our_env = new0(char*, 5); + our_env = new0(char*, 4); if (!our_env) { r = -ENOMEM; goto fail; @@ -1768,12 +1768,6 @@ static int service_spawn( goto fail; } - if (s->watchdog_usec > 0) - if (asprintf(our_env + n_env++, "WATCHDOG_USEC=%llu", (unsigned long long) s->watchdog_usec) < 0) { - r = -ENOMEM; - goto fail; - } - if (UNIT(s)->manager->running_as != SYSTEMD_SYSTEM) if (asprintf(our_env + n_env++, "MANAGERPID=%lu", (unsigned long) getpid()) < 0) { r = -ENOMEM; @@ -1804,6 +1798,7 @@ static int service_spawn( UNIT(s)->manager->cgroup_supported, path, UNIT(s)->id, + s->watchdog_usec, s->type == SERVICE_IDLE ?
