2014-03-19sd-bus: add proper monitoring APILennart Poettering
2014-03-19busname: introduce Activating directiveDaniel Mack
Add a new config 'Activating' directive which denotes whether a busname is actually registered on the bus. It defaults to 'yes'. If set to 'no', the .busname unit only uploads policy, which will remain active as long as the unit is running.
2014-03-19core: when creating an activating busname attach all metadata fields to the ↵Lennart Poettering
messages queued for it This way we can be sure that the service the messages are ultimately intended for finds all fields it might need.
2014-03-19update kdbus.hLennart Poettering
2014-03-18sd-bus: if we got a message with fds attached even though we didn't ↵Lennart Poettering
negotiate it, refuse to take it This makes sure we don't mishandle if developers specificy a different AcceptFileDescriptors= setting in .busname units then they set for the bus connection in the activated program.
2014-03-18core: add new AcceptFD= setting to .busname unitsLennart Poettering
AcceptFD= defaults to true, thus making sure that by default fd passing is enabled for all activatable names. Since for normal bus connections fd passing is enabled too by default this makes sure fd passing works correctly regardless whether a service is already activated or not. Making this configurable on both busname units and in bus connections is messy, but unavoidable since busnames are established and may queue messages before the connection feature negotiation is done by the service eventually activated. Conversely, feature negotiation on bus connections takes place before the connection acquires its names. Of course, this means developers really should make sure to keep the settings in .busname units in sync with what they later intend to negotiate.

2014-03-18util: replace close_nointr_nofail() by a more useful safe_close()Lennart Poettering
safe_close() automatically becomes a NOP when a negative fd is passed, and returns -1 unconditionally. This makes it easy to write lines like this: fd = safe_close(fd); Which will close an fd if it is open, and reset the fd variable correctly. By making use of this new scheme we can drop a > 200 lines of code that was required to test for non-negative fds or to reset the closed fd variable afterwards.
2014-03-17build-sys: move sd-login src/login → src/libsystemd/sd-loginLennart Poettering
After all, it is ultimately linked to libsystems.so anyway, thus belongs there and shares very little with the rest of logind, hence let's move this away.
2014-03-17sd-login: add calls that retrieve credentials of peers connected to AF_UNIX ↵Lennart Poettering
peers This is supposed to be an extension of SO_PEERCRED and SO_PEERSEC, except for cgroup information.
2014-03-17core, libsystemd, systemd, timedate, udev: spelling fixesMiklos Vajna
2014-03-17systemctl: introduce -r switch to show units running in local containers in ↵Lennart Poettering
addition to the host
2014-03-16Use strlen even for constant stringsJosh Triplett
GCC optimizes strlen("string constant") to a constant, even with -O0. Thus, replace patterns like sizeof("string constant")-1 with strlen("string constant") where possible, for clarity. In particular, for expressions intended to add up the lengths of components going into a string, this often makes it clearer that the expression counts the trailing '\0' exactly once, by putting the +1 for the '\0' at the end of the expression, rather than hidden in a sizeof in the middle of the expression.
2014-03-16sd-rtnl: never treat broadcasts as repliesTom Gundersen
Otherwise the sequence number of a broadcast may match the sequence number of a pending unicast message and cause confusion.
2014-03-15sd-rtnl: make RTM_NEWLINK report EEXIST by defaultTom Gundersen
Use RTM_SETLINK to update an existing link.
2014-03-14sd-bus: don't choke if somebody sends us a message with a unix fd count of 0Lennart Poettering
It's kinda pointless to include a unix fd header field in messages if it carries the value 0, but let's do this anyway...
2014-03-14sd-bus: don't access invalid memory if a signal matcher was freed from its ↵Lennart Poettering
own callback
2014-03-13sd-bus: don't look for a 64bit value when we only have 32bit value on reply ↵Lennart Poettering
cookie hash table access This broke hashtable lookups for the message cookies on s390x, which is a 64bit BE machine where accessing 32bit values as 64bit and vice versa will explode. Also, while we are at it, be a bit more careful when dealing with the 64bit cookies we expose and the 32bit serial numbers dbus uses in its payload. Problem identified by Fridrich Strba.
2014-03-13bus: fix memory leak when kdbus is not enabledLennart Poettering
2014-03-12sd-login: add sd_machine_get_class() callLennart Poettering
2014-03-11bus: replace sd_bus_label_{escape,unescape}() by new ↵Lennart Poettering
sd_bus_path_{encode,decode}() The new calls work similarly, but enforce a that a common, fixed bus path prefix is used. This follows discussions with Simon McVittie on IRC that it should be a good idea to make sure that people don't use the escaping applied here too wildly as anything other than the last label of a bus path.
2014-03-08sd-bus: sync kdbus.hDaniel Mack
2014-03-08sd-bus: check for potential integer overflow in KDBUS_ITEM_FOREACH()Daniel Mack
For large values of item->size, the 'part' pointer can wrap around, which results in an illegal pointer, but currently passes the for-loop condition.
2014-03-08sd-rtnl: increase default timeout to match sd-busTom Gundersen
2014-03-07sd-bus: add support for policy upload on activator connectionsDaniel Mack
Activator connections may upload policy when registering to the bus. This patch contains code to translate between BusNamePolicy objects and the kdbus specific items.
2014-03-07sd-bus: sync kdbus.h (ABI break)Daniel Mack
Bring kdbus.h in sync with recent policy related changes. Most notably, KDBUS_MAKE_POLICY_OPEN is now gone. The rest doesn't matter for systemd at this point, as the policy functionality was not yet used.
2014-03-07sd-rtnl: introduce read ether and ip address functionsSusant Sahani
This patch introduces reading ethernet address and IPV4/IPv6 as well which is based on table based look up. [tomegun: rename read_ether() to read_ether_addr() to match the append function.]
2014-03-06man: describe functions for appending to messagesZbigniew Jędrzejewski-Szmek
2014-03-06sd-rtnl/networkd: use new rtnl_message_read() API and drop helperTom Gundersen
With the new sd_rtnl_message_read_string(), there is no longer a need for rtnl_message_get_ifname().
2014-03-06sd-rtnl:introduce table-based lookup and typesafe read() functionsSusant Sahani
This patch introduces new netlink attribute parsing logic which is table based lookup and sd_rtnl_message_read_* methods for reading attributes. By doing this user does not have to loop for the attribute values . Only providing the attribute type it gets the attribute values which is optimized and sd_rtnl_message_read_* methods are simplified.
2014-03-05sd-rtnl: do not blindly enter containers in message_read()Tom Gundersen
We need a separate container_enter() function, which will be part of a largerg API change. For now, just fix message_read().
2014-03-05systemd-run: support all currently exported properties with -pLennart Poettering
2014-03-05core: make the LimitXYZ= properties settable for transient service unitsLennart Poettering
2014-03-05systemd-run: add new --property= switch that can set arbitrary properties ↵Lennart Poettering
for the unit that is created The code for parsing these properties is shared with "systemctl set-property", which means all the resource control settings are immediately available.
2014-03-04Introduce strv_consume which takes ownershipZbigniew Jędrzejewski-Szmek
This mirrors set_consume and makes the common use a bit nicer.
2014-03-03sd-network: IPv4 link-local support [v2]Umut Tezduyar Lindskog
Implements IPv4LL with respect to RFC 3927 (http://tools.ietf.org/rfc/rfc3927.txt) and integrates it with networkd. Majority of the IPv4LL state machine is taken from avahi (http://avahi.org/) project's autoip. IPv4LL can be enabled by IPv4LL=yes under [Network] section of .network file. IPv4LL works independent of DHCP but if DHCP lease is aquired, then LL address will be dropped. [tomegun: removed a trailing newline and a compiler warning]

2014-03-03bus: add sd_bus_track object for tracking peers, and port core over to itLennart Poettering
This is primarily useful for services that need to track clients which reference certain objects they maintain, or which explicitly want to subscribe to certain events. Something like this is done in a large number of services, and not trivial to do. Hence, let's unify this at one place. This also ports over PID 1 to use this to ensure that subscriptions to job and manager events are correctly tracked. As a side-effect this makes sure we properly serialize and restore the track list across daemon reexec/reload, which didn't work correctly before. This also simplifies how we distribute messages to broadcast to the direct busses: we only track subscriptions for the API bus and implicitly assume that all direct busses are subscribed. This should be a pretty OK simplification since clients connected via direct bus connections are shortlived anyway.
2014-02-25Use /var/run/dbus/system_bus_socket for the D-Bus socketZbigniew Jędrzejewski-Szmek
2014-02-26Revert back to /var/run at a couple of problemsLennart Poettering
This partially reverts 41a55c46ab8fb4ef6727434227071321fc762cce Some specifications we want to stay compatibility actually document /var/run, not /run, and we should stay compatible with that. In order to make sure our D-Bus implementation works on any system, regardless if running systemd or not, we should always use /var/run which is the only path mandated by the D-Bus spec. Similar, glibc hardcodes the utmp location to /var/run, and this is exposed in _UTMP_PATH in limits.h, hence let's stay in sync with this public API, too. We simply do not support systems where /var/run is not a symlink → /run. Hence both are equivalent. Staying compatible with upstream specifications hence weighs more than cleaning up superficial appearance.
2014-02-25Replace /var/run with /run in remaining placesZbigniew Jędrzejewski-Szmek
/run was already used almost everywhere, fix the remaining places for consistency.

2014-02-22test: always use assert_se in testsTom Gundersen
2014-02-21event: add new kind of event source called "post"Lennart Poettering
This new event source is triggered by the dispatching of any non-post event source. It can thus be used to do clean-up or recheck work, triggered by any other event source having been executed. This is different from "defer" event source which are unconditionally triggered as long as they are enabled. A "defer" event source that does nothing will result in the event loop busy looping unless it is turned off eventually. This is different for "post" event sources that will be only triggered when some other non-post ran, and will thus not keep the event loop busy on its own.
2014-02-21sd-event: Fix systemd crash when using timer units.Thomas Bächler
There was a copy-paste error introduced in commit c2ba3ad6604ef2e189d7e0a36d6911116e84d3ab which causes the following error when using timer units: Assertion '(x->type == SOURCE_MONOTONIC && y->type == SOURCE_MONOTONIC) || (x->type == SOURCE_REALTIME && y->type == SOURCE_REALTIME)' failed at src/libsystemd/sd-event/sd-event.c:264, function latest_time_prioq_compare(). Aborting.
2014-02-20libsystemd: fix compiler warning in property_get_set_callbacks_run()Daniel Mack
gcc (4.8.2, arm) doesn't understand that vtable_property_get_userdata() will always set 'u' when it returns > 0. Hence, the warning is bogus, but anyway. src/libsystemd/sd-bus/bus-objects.c:510:19: warning: 'u' may be used uninitialized in this function [-Wmaybe-uninitialized] (and yes, indeed, even the reported line numbers are bogus in this case)
