2013-12-12bus: add SD_BUS_NAME_REPLACE_EXISTING to all activatable services, fix one ↵Kay Sievers
flags conversion
2013-12-12bus: instead of exposing the dbus1 flags when acquiring a name use our own ↵Lennart Poettering
that are closer to kdbus This turns around DO_NOT_QUEUE into QUEUE which implies a more useful default. (And negative options are awful anyway.)
2013-12-12bus: properly return an error when we detect a method call timeoutLennart Poettering
2013-12-12core: fix bus registration on daemon reexecLennart Poettering
2013-12-11nspawn: complain and continue if machine has same idZbigniew Jędrzejewski-Szmek
If --link-journal=host or --link-journal=guest is used, this totally cannot work and we exit with an error. If however --link-journal=auto or --link-journal=no is used, just display a warning. Having the same machine id can happen if booting from the same filesystem as the host. Since other things mostly function correctly, let's allow that. https://bugs.freedesktop.org/show_bug.cgi?id=68369
2013-12-11Do not log all assert_return failuresZbigniew Jędrzejewski-Szmek
% build/journalctl help Assertion 'match_is_valid(data, size)' failed at ../src/journal/sd-journal.c:227, function sd_journal_add_match(). Ignoring. Callers cannot be expect to check all arguments always.
2013-12-11journal: pipe journalctl help output into a pagerDjalal Harouni
journalctl help output might run off the screen, so be consistent as other systemd tools do and pipe it into a pager.
2013-12-11man: mention SYSTEMD_USER_WANTSZbigniew Jędrzejewski-Szmek
Also split into paragraphs for easier reading and make a few minor corrections.
2013-12-12service: actually leave watchdog enabled in the states where it mattersLennart Poettering
2013-12-12timedated: make sure GetAll() succeeds in systems lacking /dev/rtc (such as ↵Lennart Poettering
containers)
2013-12-12test-fileio: replace mktemp with mkstemp to avoid warningsThomas Hindoe Paaboel Andersen
This is a fairly useless thing to do but it makes the compilers and analyzers shut up about the use of mktemp.
2013-12-12bus: properly generate NameOwnerChanged messages when we take from/give back ↵Lennart Poettering
to queue/starter
2013-12-12bus: fix order in which we check credsLennart Poettering
2013-12-12update TODOLennart Poettering
2013-12-12bus: update name listing logic to current kernel interfaceLennart Poettering
2013-12-12bus: when checking whether a creds object contains some field, don't use ↵Lennart Poettering
assert_return() These are not programming errors, so they shouldn't use assert_return()
2013-12-12bus: connect directly via kdbus in sd_bus_open_system_container()Lennart Poettering
kdbus fortunately exposes the container's busses in the host fs, hence we can access it directly instead of doing the namespacing dance.
2013-12-11sd-event: try to move each wakeup to the same spot within every 10sLennart Poettering
In addition to the same spot within every 1min, every 1s, every 250s
2013-12-11journald: make sure the stdout/stderr stream fd is removed from epoll before ↵Lennart Poettering
we close it
2013-12-11units: don't run readahead done timers in containersLennart Poettering
We don't run the collector in the container either, hence we don't need to stop it either.
2013-12-11journald: cache cgroup root path, instead of querying it on every incoming ↵Lennart Poettering
log message
2013-12-11journal: when listing logs of a container make sure we don't accidentally ↵Lennart Poettering
show messages from host too
2013-12-11journald: cache hostname, boot_id and machine_id fields instead of ↵Lennart Poettering
generating them fresh for each log entry
2013-12-11journal: don't go belly up when an stdout/stderr client terminates the ↵Lennart Poettering
connection
2013-12-11journal: add ability to browse journals of running OS containersLennart Poettering
This adds the new library call sd_journal_open_container() and a new "-M" switch to journalctl. Particular care is taken that journalctl's "-b" switch resolves to the current boot ID of the container, not the host.
2013-12-11service: clean up watchdog logic a bitLennart Poettering
2013-12-11journald: port to sd-event and enable watchdog supportLennart Poettering
2013-12-11man: explain in more detail how SYSTEMD_READY= influences SYSTEMD_WANTS= in ↵Lennart Poettering
udev rules https://bugzilla.redhat.com/show_bug.cgi?id=1026860
2013-12-11event: hook up sd-event with the service watchdog logicLennart Poettering
Adds a new call sd_event_set_watchdog() that can be used to hook up the event loop with the watchdog supervision logic of systemd. If enabled and $WATCHDOG_USEC is set the event loop will ping the invoking systemd daemon right after coming back from epoll_wait() but not more often than $WATCHDOG_USEC/4. The epoll_wait() will sleep no longer than $WATCHDOG_USEC/4*3, to make sure the service manager is called in time. This means that setting WatchdogSec= in a .service file and calling sd_event_set_watchdog() in your daemon is enough to hook it up with the watchdog logic.
2013-12-11event: when handling SIGCHLD of a child process only reap after dispatching ↵Lennart Poettering
event source That way the even source callback is run with the zombie process still around so that it can access /proc/$PID/ and similar, and so that it can be sure that the PID has not been reused yet.
2013-12-11bus: kdbus - skip only STARTER and IN_QUEUE names for NameOwnerChangedKay Sievers
2013-12-10activate: clean up inherited descriptorsZbigniew Jędrzejewski-Szmek
> [simon@troela server]$ /usr/lib/systemd/systemd-activate -l 9000 main.js > Assertion 'fd == 3 + count' failed at src/activate/activate.c:115, > function open_sockets(). Aborting. > Aborted (core dumped) > after a bit debuging i found the problem: > slim appears to leak an fd into all of its children: > stat /proc/14004/fd/3 (14004 is the pid a random process in my session) > File: '/proc/14004/fd/3' -> '/var/log/slim.log' systemd-activate should be robust against the shell (or anything else) leaking descriptors. Now everything except stdin/stdout/stderr and received sockets will be closed.

2013-12-11ptyfwd: Don't set the output prop of stdin, nor the input props of stdout.Luke Shumaker
It was calling cfmakeraw(3) on the properties for STDIN_FILENO; cfmakeraw sets both input and output properties. If (and only if) stdin and stdout are the same device is this correct. Otherwise, we must change only the input properties of stdin, and only the output properties of stdout.
2013-12-11ptyfwd: Set the size of the PTY base on the size of stdout, not stdin.Luke Shumaker
2013-12-10core: fix Unit.SetProperties argument parsingDavid Herrmann
SetProperties has signature "ba(sv)", but the bus_unit_set_properties() helper already does a enter_container('a', "sv") so we have to skip it in bus_unit_method_set_properties().
2013-12-10bus: do not dispatch incoming method calls that are broacasted to vtablesLennart Poettering
2013-12-10bus: don't generate assert warnings when we detach a detached bus from an eventLennart Poettering

2013-12-10core: epoll and signalfd has been moved into sd event loopShawn Landden
2013-12-10fix scan-build issuesThomas Hindoe Paaboel Andersen
The static analyzer scan-build had a few issues with analysing parts of systemd. gpt-auto-generator.c: scan-build could not find blkid.h. Whether it should be blkid.h or blkid/blkid.h seems to depend on the version used. We already use blkid/blkid.h in udev-builtin-blkid.c so it seems safe to use that here too. Makefile.am: Moved some -D's from CFLAGS to CPPFLAGS. I also simplified them a bit and got rid of a left over DBUS_CFLAGS. test-cgroup-mask.c/test-sched-prio.c A variable was added to store the replaced TEST_DIR. When wrapped in an assert_se TEST_DIR was not replaced in the logged error. While not an issue introduced in this patch we might as well fix it up while we are here.
2013-12-10bus: generate debug messages when we cannot deliver messages via kdbusLennart Poettering
2013-12-10bus: when we _unref() a NULL pointer, don't use assert_return()Lennart Poettering
We support unreffing NULL pointers just fine and we shouldn't pay the _unlikely_() price for it, not get a debug message if we do, hence let's not use assert_return() here.

2013-12-10Revert "libsystemd-bus: use assert_return"Lennart Poettering
This reverts commit f7e2bd5a8070ba86cba6bcbf7d1c9a8173d846d4. Most of these checks are not programming errors, but happen during normal runtime. For example bus_kernel_pop_memfd() is called all the time on non-kdbus systems and is supposed to quickly fail if kdbus is not available. However, assert_return() makes this failure expensive, and hence has no place here. With the most recent change to assert_return() it will even log a debug message, which should never happen here.
2013-12-10Revert "systemd: add a start job for all units in SYSTEMD_[USER_]WANTS="Lennart Poettering
This reverts commit e775289d56ace2f8d23e62ed79316d71332d6d05. We really should let the dependency logic add jobs for dependencies here rather than manually adding in jobs, overtaping the real problem.
