These patches add two new options for journald.conf: * ForwardToWall (default yes) * MaxLevelWall (default emerg)
When ForwardToWall is yes, journald forwards all log messages equal or below MaxLevelWall to utmp_wall(). This can be used to send emergency messages to logged-in users. A forwarded log message looks like this when it gets written to a user's terminal: Broadcast message from systemd-journald at hostname (Wed 2014-03-05 13:00:00 CET): some-process[4711]: This is an emergency log message from some-process! See http://lists.freedesktop.org/archives/systemd-devel/2014-March/017610.html for v1 of this patch. Changes since v3: * Added missing documentation of new kernel parameter systemd.journald.forward_to_wall= to kernel-command-line(7) and systemd-journald.service(8) Sebastian Thorarensen (2): utmp-wtmp: allow overriding username on wall journald: add support for wall forwarding Makefile.am | 2 + man/journald.conf.xml | 40 +++++++----- man/kernel-command-line.xml | 1 + man/systemd-journald.service.xml | 5 +- src/journal/journald-gperf.gperf | 2 + src/journal/journald-native.c | 4 ++ src/journal/journald-server.c | 8 +++ src/journal/journald-server.h | 2 + src/journal/journald-stream.c | 4 ++ src/journal/journald-syslog.c | 4 ++ src/journal/journald-wall.c | 67 ++++++++++++++++++++ src/journal/journald-wall.h | 26 ++++++++ src/journal/journald.conf | 2 + src/shared/utmp-wtmp.c | 12 ++-- src/shared/utmp-wtmp.h | 2 +- src/shutdownd/shutdownd.c | 2 +- src/systemctl/systemctl.c | 4 +- .../tty-ask-password-agent.c | 2 +- 18 files changed, 162 insertions(+), 27 deletions(-) create mode 100644 src/journal/journald-wall.c create mode 100644 src/journal/journald-wall.h -- 1.7.10.4 _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
