2015-07-07service: if logging start app with LD_PRELOAD & lib for line bufferingRafał Miłecki
Using pipe automatically switches service to block buffering which kind of breaks our logging. We won't get anything from stdout FD until the buffer gets filled fully or the service exits. This makes log messages appear with an unwanted delay. This change adds a tiny libsetlbf.so switching stdout to line buffering and uses this lib for every logging-enabled service started by procd. We don't need any extra change for stderr as it's unbuffered by default. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Modified to use no buffering to align with stderr. Several cleanups.

2015-05-05instance: handle setgid() before setuid()Jo-Philipp Wich
When attempting to run a service with an unprivileged user and group id procd, the following error might occur: procd: failed to set uid:1000, gid:1000 This is due to the fact that procd first performs the setuid(), then the setgid() call. Usually there no sufficient permissions after a setuid() anymore to change the effective group id of the process. Refactor the code to: * Swap the invocations (first gid, then uid) * Don't set user or group id if it is 0 * Handle errors independently and make them more verbose Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>

2015-02-26procd: support relayoing daemon stdout/stderr to syslogJo-Philipp Wich
This commit adds support to procd for relaying stdout and stderr streams to the system log. That is mainly useful for services not using syslog, e.g. uhttpd. Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>

2013-12-18procd: fix service file trackingJo-Philipp Wich
The instance_config_move() function in the procd instance managing code is missing a blobmsg_list_move() call to update the tracked file items with the newly calculated checksums in case of a file change. Without that change, services are always reloaded after the first change to a tracked file regardless of whether there are any subsequent changes or not. Add a missing instance of blobmsg_list_free() as well. Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>
