Package: mumble-server Version: 1.3.0~git20190125.440b173+dfsg-2 Severity: normal
Hi, currently /etc/init.d/mumble-server stop doesn't does not stop the murmurd and "restart" spawns an additional instance of mumble-server, leading to various problems. I'd assume "force-reload" is similarly affected. This is caused by two separate issues: First the init script specifies "--user $USER", where $USER is "root" by default. But murmur will (by default) drop itself to "mumble-server" user; so this flag prevents start-stop-daemon from finding the process. Removing the --user switches resolves this part. I've included the modified init-script below. Second murmur does not write its own pidfile in the default setup. I was able to fix this with chown root:mumble-server $PIDDIR && chmod g+w PIDDIR This is a bit crude though and ideally murmurd would write its pidfile _before_ dropping privileges instead if that's possible. Apparently murmurd already does read ssl certificates before dropping privileges. There's also a related upstream issue, albeit apparently stale: https://github.com/mumble-voip/mumble/issues/2388 ~~ Nils -- System Information: Distributor ID: Raspbian Description: Raspbian GNU/Linux 10 (buster) Release: 10 Codename: buster Architecture: armv7l Kernel: Linux 5.4.83-v7+ (SMP w/4 CPU cores) Kernel taint flags: TAINT_CRAP Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages mumble-server depends on: ii adduser 3.118 ii debconf [debconf-2.0] 1.5.71 ii libatomic1 8.3.0-6+rpi1 ii libavahi-client3 0.7-4+b1 ii libavahi-common3 0.7-4+b1 ii libavahi-compat-libdnssd1 0.7-4+b1 ii libc6 2.28-10+rpi1 ii libcap2 1:2.25-2 ii libgcc1 1:8.3.0-6+rpi1 ii libprotobuf17 3.6.1.3-2+rpi1 ii libqt5core5a 5.11.3+dfsg1-1+rpi1+deb10u4 ii libqt5dbus5 5.11.3+dfsg1-1+rpi1+deb10u4 ii libqt5network5 5.11.3+dfsg1-1+rpi1+deb10u4 ii libqt5sql5 5.11.3+dfsg1-1+rpi1+deb10u4 ii libqt5sql5-sqlite 5.11.3+dfsg1-1+rpi1+deb10u4 ii libqt5xml5 5.11.3+dfsg1-1+rpi1+deb10u4 ii libssl1.1 1.1.1d-0+deb10u4+rpt1 ii libstdc++6 8.3.0-6+rpi1 ii libzeroc-ice3.7 3.7.2-4 ii lsb-base 10.2019051400+rpi1 mumble-server recommends no packages. mumble-server suggests no packages. -- Configuration Files: /etc/init.d/mumble-server changed: PATH=/sbin:/bin:/usr/sbin:/usr/bin NAME=mumble-server DESC="Mumble VoIP Server" PIDDIR=/run/$NAME PIDFILE=$PIDDIR/$NAME.pid DAEMON=/usr/sbin/murmurd #USER=mumble-server # mumble will drop to 'mumble-server' itself USER=root GROUP=mumble-server test -x $DAEMON || exit 0 INIFILE=/etc/mumble-server.ini DAEMON_OPTS="-ini $INIFILE" MURMUR_USE_CAPABILITIES=0 MURMUR_LIMIT_NOFILE=0 if [ -f /etc/default/$NAME ] ; then . /etc/default/$NAME fi . /lib/init/vars.sh . /lib/lsb/init-functions if [ "$MURMUR_LIMIT_NOFILE" -gt 0 ] ; then ulimit -n $MURMUR_LIMIT_NOFILE fi case "$1" in start) [ "$VERBOSE" != no ] && log_daemon_msg "Starting $DESC" "$NAME" [ -d $PIDDIR ] || install -o $USER -d $PIDDIR if [ "$MURMUR_USE_CAPABILITIES" != "1" ] ; then start-stop-daemon --start --quiet \ --pidfile $PIDFILE \ --chuid $USER:$GROUP \ --exec $DAEMON \ -- $DAEMON_OPTS else start-stop-daemon --start --quiet \ --pidfile $PIDFILE \ --exec $DAEMON \ -- $DAEMON_OPTS fi case "$?" in 0|1) [ "$VERBOSE" != no ] && log_end_msg 0 ;; 2) [ "$VERBOSE" != no ] && log_end_msg 1 ;; esac ;; stop) [ "$VERBOSE" != no ] && log_daemon_msg "Stopping $DESC" "$NAME" start-stop-daemon --stop --quiet \ --retry=TERM/30/KILL/5 \ --pidfile $PIDFILE \ --exec $DAEMON #--user $USER \ case "$?" in 0|1) rm -f $PIDFILE [ "$VERBOSE" != no ] && log_end_msg 0 ;; 2) [ "$VERBOSE" != no ] && log_end_msg 1 ;; esac ;; status) if start-stop-daemon --test --stop --quiet \ --pidfile $PIDFILE \ --exec $DAEMON #--user $USER \ then [ "$VERBOSE" != no ] && echo "$DESC is running." exit 0 else [ "$VERBOSE" != no ] && echo "$DESC is not running" exit 3 fi ;; force-reload) #--user $USER \ start-stop-daemon --stop --test --quiet \ --pidfile $PIDFILE \ --exec $DAEMON \ && $0 restart || exit 0 ;; restart) [ "$VERBOSE" != no ] && log_daemon_msg "Restarting $DESC" "$NAME" start-stop-daemon --stop --quiet \ --retry=TERM/30/KILL/5 \ --pidfile $PIDFILE \ --exec $DAEMON #--user $USER \ case "$?" in 0|1) [ -d $PIDDIR ] || install -o $USER -d $PIDDIR rm -f $PIDFILE if [ "$MURMUR_USE_CAPABILITIES" != "1" ] ; then start-stop-daemon --start --quiet \ --pidfile $PIDFILE \ --chuid $USER:$GROUP \ --exec $DAEMON \ -- $DAEMON_OPTS else start-stop-daemon --start --quiet \ --pidfile $PIDFILE \ --exec $DAEMON \ -- $DAEMON_OPTS fi case "$?" in 0) [ "$VERBOSE" != no ] && log_end_msg 0 ;; *) [ "$VERBOSE" != no ] && log_end_msg 1 ;; esac ;; *) [ "$VERBOSE" != no ] && log_end_msg 0 ;; esac ;; *) N=/etc/init.d/$NAME echo "Usage: $N {start|stop|restart|force-reload}" >&2 exit 3 ;; esac exit 0 -- debconf information: mumble-server/start_daemon: true mumble-server/use_capabilities: false
