2015-04-29sd-bus: benchmark - also support testing non-kdbus transportsTom Gundersen
We introduce two news types of benchmarks in chart-mode: - 'legacy' connects using the session bus - 'direct' connects using a peer-to-peer socket We should probably also introduce a mode for testing the dbus1-kdbus proxy.
2015-04-28bus-util: drop redundant bus argument from bus_message_map_all_properties() ↵Lennart Poettering
and related calls
2015-04-28run: synchronously wait until the scope unit we create is startedLennart Poettering
Otherwise it might happen that by the time PID 1 adds our process to the scope unit the process might already have died, if the process is short-running (such as an invocation to /bin/true). https://bugs.freedesktop.org/show_bug.cgi?id=86520
2015-04-28bus-util: print correct warnings for units that fail but for which we have a ↵Lennart Poettering
NULL result only
2015-04-26sd-device: don't retry loading uevent/db files more than onceTom Gundersen
If for whatever reason there was nothing to load or loading failed, don't keep trying.
2015-04-26sd-device: don't complain if the uevent file is missingTom Gundersen
Only 'real' devices are required to have an uevent file.
2015-04-24sd-bus: teach bus_print_property() how to print SD_BUS_TYPE_INT64Daniel Mack
2015-04-23udevd: fix REMOVE handlingTom Gundersen
This reverts b67f944. Lazy loading of device properties does not work for devices that are received over netlink, as these are sealed. Reinstate the unconditional loading of the device db. Reported by: Mantas Mikulėnas <grawity@gmail.com>.
2015-04-23sd-bus: add controlling tty field to sd_creds objectLennart Poettering
This is useful to print wall messages from logind with the right client tty. (to be added in a later patch)
2015-04-23sd-bus: when bus operations are to be executed on direct connections always failLennart Poettering
Also, don't consider this an loggable event, so that code that tries to read creds from a direct connection, doesn't generate logs.
2015-04-23sd-bus: don't inherit connection creds into message creds when we have a ↵Lennart Poettering
direct connection It's never a good idea, let's just not do it, not even on dierct connections.
2015-04-23core: explicitly specify credentials for direct connections, tooLennart Poettering
So far we authenticate direct connections primarily at connection time, but let's also do this for each method individually, by attaching the creds we need for that right away.
2015-04-22sd-bus: handle ppid=0 more gracefully (which happens for pid=1)Lennart Poettering
2015-04-21sd-bus: expose ppid fieldLennart Poettering
kdbus has been passing us the ppid file for a while, actually make use of it.

2015-04-21sd-bus: when augmenting creds, remember which ones were augmentedLennart Poettering
Also, when we do permissions checks using creds, verify that we don't do so based on augmented creds, as extra safety check.
2015-04-21sd-bus: augmenting cgroups-based creds when we have the cgroup path already ↵Lennart Poettering

2015-04-21sd-bus: when augmenting creds, don't override any creds in any caseLennart Poettering
Let's better be safe than sorry.

2015-04-17sd-device: simplify enumerator hacksDavid Herrmann
Boolean arithmetic is great, use it! if (a && !b) return 1; if (!a && b) return -1, is equivalent to if (a != b) return a - b; Furthermore: r = false; if (condition) r = true; is equivalent to: r = condition;
2015-04-17sd-device: uniformly handle missing devicesTom Gundersen
sd_device_new_from_* now returns -ENODEV when the device does not exist, and the enumerator silently drops these errors as missing devices is exepected.
2015-04-17sd-device: enumerator - match only on initialized devices by defaultTom Gundersen
It is still possible to include uninitialized ones, but now that is opt-in. In most cases people only want initialized devices. Exception is if you want to work without udev running. Suggested by David Herrmann.
2015-04-17sd-device: enumerator - don't expose add_device()Tom Gundersen
This is rarely, if ever, used. Drop it from the new public API and only keep it for the legacy API. Suggested by David Herrmann.
2015-04-16sd-device: add device-enumerator libraryTom Gundersen

2015-04-12bus-util: add articles to explanation messagesZbigniew Jędrzejewski-Szmek
We are talking about one member of a group of things (resource limits, signals, timeouts), without specifying which one. An indenfinite article is in order. When we are talking about the control process, it's a specific one, so the definite article is used.
2015-04-11bus: implement bus_path_{en,de}code_unique()David Herrmann
Whenever we provide a bus API that allows clients to create and manage server-side objects, we need to provide a unique name for these objects. There are two ways to provide them: 1) Let the server choose a name and return it as method reply. 2) Let the client pass its name of choice in the method arguments. The first method is the easiest one to implement. However, it suffers from a race condition: If a client creates an object asynchronously, it cannot destroy that object until it received the method reply. It cannot know the name of the new object, thus, it cannot destroy it. Furthermore, this method enforces a round-trip. If the client _depends_ on the method call to succeed (eg., it would close() the connection if it failed), the client usually has no reason to wait for the method reply. Instead, the client can immediately schedule further method calls on the newly created object (in case the API guarantees in-order method-call handling). The second method fixes both problems: The client passes an object name with the method-call. The server uses it to create the object. Therefore, the client can schedule object destruction even if the object-creation hasn't finished, yet (again, requiring in-order method-call handling). Furthermore, the client can schedule further method calls on the newly created object, before the constructor returned. There're two problems to solve, though: 1) Object names are usually defined via dbus object paths, which are usually globally namespaced. Therefore, multiple clients must be able to choose unique object names without interference. 2) If multiple libraries share the same bus connection, they must be able to choose unique object names without interference. The first problem is solved easily by prefixing a name with the unique-bus-name of a connection. The server side must enforce this and reject any other name. The second problem is solved by providing unique suffixes from within sd-bus. As long as sd-bus always returns a fresh new ID, if requested, multiple libraries will never interfere. This implementation re-uses bus->cookie as ID generator, which already provides unique IDs for each bus connection. This patch introduces two new helpers: bus_path_encode_unique(sd_bus *bus, const char *prefix, const char *sender_id, const char *external_id, char **ret_path); This creates a new object-path via the template '/prefix/sender_id/external_id'. That is, it appends two new labels to the given prefix. If 'sender_id' is NULL, it will use bus->unique_name, if 'external_id' is NULL, it will allocate a fresh, unique cookie from bus->cookie. bus_path_decode_unique(const char *path, const char *prefix, char **ret_sender, char **ret_external); This reverses what bus_path_encode_unique() did. It parses 'path' from the template '/prefix/sender/external' and returns both suffix-labels in 'ret_sender' and 'ret_external'. In case the template does not match, 0 is returned and both output arguments are set to NULL. Otherwise, 1 is returned and the output arguments contain the decoded labels. Note: Client-side allocated IDs are inspired by the Wayland protocol (which itself was inspired by X11). Wayland uses those IDs heavily to avoid round-trips. Clients can create server-side objects and send method calls without any round-trip and waiting for any object IDs to be returned. But unlike Wayland, DBus uses gobally namespaced object names. Therefore, we have to add the extra step by adding the unique-name of the bus connection.

2015-04-10sd-event: simplify sd_event_run()Lennart Poettering
2015-04-10bus-util: be more verbose if dbus job failsMichal Sekletar
Users might have hard time figuring out why exactly their systemctl request failed. If dbus job fails try to figure out more details about failure by examining Result property of the service. https://bugzilla.redhat.com/show_bug.cgi?id=1016680
2015-04-09bus: simplify bus_message_read_strv_extend()David Herrmann
Avoid unbound for(;;) loop and use the established coding-style: while ((r = sd_bus_message_read*(...)) > 0) { } if (r < 0) return r; This is much easier to read and used all over the code base.
2015-04-09bus: use free_and_strdup()David Herrmann
Save some LOCs by replacing strdup()+error-handling+free+assign with free_and_strdup().
2015-04-09util: add shell_maybe_quote() call for preparing a string for shell cmdline ↵Lennart Poettering
inclusion If necessary the passed string is enclosed in "", and all special characters escapes. This also ports over usage in bus-util.c and job.c to use this, instead of a incorrect local implementation that forgets to properly escape.

2015-04-07polkit: rename bus_verify_polkit() to bus_test_polkit() and make it strictly ↵Lennart Poettering
non-interactive Interactive authorization should only happen asynchronously, hence disallow it in synchronous bus_verify_polkit(), and rename it to bus_test_polkit(). This way even if the bus message header asks for interactive authorization, we'll ask for non-interactive authorization which is actually the desired behaviour if CanSuspend, CanHibernate and friends, which call this function.
2015-04-07util: rework cunescape(), improve error handlingLennart Poettering
Change cunescape() to return a normal error code, so that we can distuingish OOM errors from parse errors. This also adds a flags parameter to control whether "relaxed" or normal parsing shall be done. If set no parse failures are generated, and the only reason why cunescape() can fail is OOM.
2015-04-07device: fix sysattr newline cutterDavid Herrmann
Right now, we always drop the last character of all values we write to sysfs. Fix this!

2015-04-03sd-device: fix deserialization from netlinkTom Gundersen
Use the standard FOREACH_WORD* macros. The current code was broken in the devlink case so the last one received was being dropped, causing https://bugs.freedesktop.org/show_bug.cgi?id=89894

unnecessarily
2015-04-03sd-device: get_sysattr_value - don't leak returned valueTom Gundersen
This was getting leaked as a copy was added to the hashmap, simply add the returned value instead. This should fix CID #1292806.
