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>
