2015-11-27tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easyLennart Poettering
GLIB has recently started to officially support the gcc cleanup attribute in its public API, hence let's do the same for our APIs. With this patch we'll define an xyz_unrefp() call for each public xyz_unref() call, to make it easy to use inside a __attribute__((cleanup())) expression. Then, all code is ported over to make use of this. The new calls are also documented in the man pages, with examples how to use them (well, I only added docs where the _unref() call itself already had docs, and the examples, only cover sd_bus_unrefp() and sd_event_unrefp()). This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we tend to call our destructors these days. Note that this defines no public macro that wraps gcc's attribute and makes it easier to use. While I think it's our duty in the library to make our stuff easy to use, I figure it's not our duty to make gcc's own features easy to use on its own. Most likely, client code which wants to make use of this should define its own: #define _cleanup_(function) __attribute__((cleanup(function))) Or similar, to make the gcc feature easier to use. Making this logic public has the benefit that we can remove three header files whose only purpose was to define these functions internally. See #2008.

2015-09-29bus-util: rename bus_open_transport() to bus_connect_transport()Lennart Poettering
In sd-bus, the sd_bus_open_xyz() family of calls allocates a new bus, while sd_bus_default_xyz() family tries to reuse the thread's default bus. bus_open_transport() sometimes internally uses the former, sometimes the latter family, but suggests it only calls the former via its name. Hence, let's avoid this confusion, and generically rename the call to bus_connect_transport(). Similar for all related calls. And while we are at it, also change cgls + cgtop to do direct systemd connections where possible, since all they do is talk to systemd itself.
2015-09-29util: introduce common version() implementation and use it everywhereLennart Poettering
This also allows us to drop build.h from a ton of files, hence do so. Since we touched the #includes of those files, let's order them properly according to CODING_STYLE.
2015-09-24hostnamed: drop redundant codeDavid Herrmann
Doing argc checks once is enough enough enough enough.
2015-09-09tree-wide: update empty-if coccinelle script to cover empty-while and moreLennart Poettering
Let's also clean up single-line while and for blocks.
2015-09-09tree-wide: drop {} from one-line if blocksLennart Poettering
Patch via coccinelle.
2015-09-09tree-wide: use coccinelle to patch a lot of code to use mfree()Lennart Poettering
This replaces this: free(p); p = NULL; by this: p = mfree(p); Change generated using coccinelle. Semantic patch is added to the sources.
2015-09-07basic: rework virtualization detection APILennart Poettering
Introduce a proper enum, and don't pass around string ids anymore. This simplifies things quite a bit, and makes virtualization detection more similar to architecture detection.
2015-09-06bus-util: support details in CheckAuthorization callsMichael Chapman
Extra details for an action can be supplied when calling polkit's CheckAuthorization method. Details are a list of key/value string pairs. Custom policy can use these details when making authorization decisions.
2015-08-05hostname-util: get rid of unused parameter of hostname_cleanup()Zbigniew Jędrzejewski-Szmek
All users are now setting lowercase=false.
2015-08-05hostnamectl: allow trailing dot on fqdnZbigniew Jędrzejewski-Szmek
When the user requests to set hostname, and we are setting both pretty and static hostnames, and the name is a valid FQDN, we use it as the static hostname, and unset the pretty hostname. The change is that a FQDN with a trailing dot is accepted and ignored. https://bugzilla.redhat.com/show_bug.cgi?id=1238246 Lowercasing of the static name is not done anymore. $ hostnamectl set-hostname Foobar. => static is "Foobar", pretty is "Foobar." $ hostnamectl set-hostname Foobar.org. => static is "Foobar.org", pretty is unset $ hostnamectl set-hostname Foobar.org.. => static is "Foobar.org", pretty is "Foobar.org.."
2015-08-05hostname-util: add relax parameter to hostname_is_validZbigniew Jędrzejewski-Szmek
Tests are modified to check behaviour with relax and without relax. New tests are added for hostname_cleanup(). Tests are moved a new file (test-hostname-util) because there's now a bunch of them. New parameter is not used anywhere, except in tests, so there should be no observable change.
2015-07-03sd-bus: introduce new sd_bus_flush_close_unref() callLennart Poettering
sd_bus_flush_close_unref() is a call that simply combines sd_bus_flush() (which writes all unwritten messages out) + sd_bus_close() (which terminates the connection, releasing all unread messages) + sd_bus_unref() (which frees the connection). The combination of this call is used pretty frequently in systemd tools right before exiting, and should also be relevant for most external clients, and is hence useful to cover in a call of its own. Previously the combination of the three calls was already done in the _cleanup_bus_close_unref_ macro, but this was only available internally. Also see #327
2015-05-19hostname: Allow comments in /etc/hostnameMartin Pitt
The hostname(1) tool allows comments in /etc/hostname. Introduce a new read_hostname_config() in hostname-util which reads a hostname configuration file like /etc/hostname, strips out comments, whitespace, and cleans the hostname. Use it in hostname-setup.c and hostnamed and remove duplicated code. Update hostname manpage. Add tests. https://launchpad.net/bugs/1053048
2015-05-18util: split all hostname related calls into hostname-util.cLennart Poettering
2015-04-29sd-bus: drop bus parameter from message callback prototypeLennart Poettering
This should simplify the prototype a bit. The bus parameter is redundant in most cases, and in the few where it matters it can be derived from the message via sd_bus_message_get_bus().
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-18logind: open up most bus calls for unpriviliged processes, using PolicyKitLennart Poettering
Also, allow clients to alter their own objects without any further priviliges. i.e. this allows clients to kill and lock their own sessions without involving PK.
2014-12-28tmpfiles: add new line type 'v' for creating btrfs subvolumesLennart Poettering
2014-12-25hostnamed: remove spurious include of <sys/capability.h>Filipe Brandenburger
It does not use any functions from libcap directly. The CAP_SYS_ADMIN constant in use by this file comes from <linux/capability.h> imported through "missing.h". Tested that "systemd-hostnamed" builds cleanly and works after this change.
2014-12-24sd-bus: rename sd_bus_open_system_container() to sd_bus_open_system_machine()Lennart Poettering
Pretty much everywhere else we use the generic term "machine" when referring to containers in API, so let's do though in sd-bus too. In particular, since the concept of a "container" exists in sd-bus too, but as part of the marshalling system.
2014-12-12util: when using basename() for creating temporary files, verify the ↵Lennart Poettering
resulting name is actually valid Also, rename filename_is_safe() to filename_is_valid(), since it actually does a full validation for what the kernel will accept as file name, it's not just a heuristic.

2014-11-28treewide: more log_*_errno + return simplificationsMichal Schmidt
2014-11-28hostnamectl: Exit with zero on successMartin Pitt
In show_all_names(), bus_map_all_properties() returns 1 on success which is then used as the return code of show_all_names() and eventually main(). Exit with zero in main() on all nonnegative results to guard against similar errors.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
2014-11-06hostnamed: introduce new "embedded" chassis typeLennart Poettering
We really don't want to get lost in adding fridge, car, plane, drone, or whatever else, hence add a generic term "embedded" cover all the cases where the computer is just part of something bigger, and not at the focus of things.
2014-10-27util: introduce sethostname_idempotentMichal Sekletar
Function queries system hostname and applies changes only when necessary. Also, migrate all client of sethostname to sethostname_idempotent while at it.
2014-10-23mac: rename apis with mac_{selinux/smack}_ prefixWaLyong Cho
2014-09-16hostname: add missing EMITS_CHANGE annotationDavid Herrmann
We call into sd-bus to send PropertiesChanged notifications for "Hostname", but forgot to add the annotation to the bus-vtable. Fix that!
2014-08-18bus-util: simplify bus_verify_polkit_async() a bitLennart Poettering
First, let's drop the "bus" argument, we can determine it from the message anyway. Secondly, determine the right callback/userdata pair automatically from what is currently is being dispatched. This should simplify things a lot for us, since it makes it unnecessary to pass pointers through the original handlers through all functions when we process messages, which might require authentication.

2014-08-15sd-bus: add API to check if a client has privilegesLennart Poettering
This is a generalization of the vtable privilege check we already have, but exported, and hence useful when preparing for a polkit change. This will deal with the complexity that on dbus1 one cannot trust the capability field we retrieve via the bus, since it is read via /proc/$$/stat (and thus might be out-of-date) rather than directly from the message (like on kdbus) or bus connection (as for uid creds on dbus1). Also, port over all code to this new API.
2014-08-15hostnamectl: actually implement location supportLennart Poettering
2014-08-15sd-bus: Remove bus arg from bus_verify_polkit_async_registry_free()Stef Walter
It's unneccessary, not used, and complicates callers of the function.
2014-08-04bus: always explicitly close bus from main programsLennart Poettering
Since b5eca3a2059f9399d1dc52cbcf9698674c4b1cf0 we don't attempt to GC busses anymore when unsent messages remain that keep their reference, when they otherwise are not referenced anymore. This means that if we explicitly want connections to go away, we need to close them. With this change we will no do so explicitly wherver we connect to the bus from a main program (and thus know when the bus connection should go away), or when we create a private bus connection, that really should go away after our use. This fixes connection leaks in the NSS and PAM modules.
2014-08-03Unify parse_argv styleZbigniew Jędrzejewski-Szmek
getopt is usually good at printing out a nice error message when commandline options are invalid. It distinguishes between an unknown option and a known option with a missing arg. It is better to let it do its job and not use opterr=0 unless we actually want to suppress messages. So remove opterr=0 in the few places where it wasn't really useful. When an error in options is encountered, we should not print a lengthy help() and overwhelm the user, when we know precisely what is wrong with the commandline. In addition, since help() prints to stdout, it should not be used except when requested with -h or --help. Also, simplify things here and there.

2014-07-11hostnamed: drop nss-myhostname checkLennart Poettering
The check only cares about whether the module is installed, not enabled. But installation we should know anyway, after all we ship the module with systemd these days...
