2016-04-12localed: downgrade libxkbcommon to an optional runtime dependencyLennart Poettering
Previously, libxkbcommon was a compile-time option. When enabled the localed binary would strictly depend on it, thus pulling in libxkbcommon and its dependencies, which are non-trivial in size. With this change we dlopen() libxkbcommon when it is available instead. If the library is available behaviour is as before. However, if it isn't the system is considered "headless", i.e. without local hardware and all attempts to set the local keyboard configuration will be refused. This is useful for general-purpose distributions which want to support "headless" (such as container systems) and "full" systems with the same build.
2016-03-01selinux: always try to load the full selinux dbZbigniew Jędrzejewski-Szmek
https://github.com/systemd/systemd/pull/2508#issuecomment-190901170 Maybe fixes https://bugzilla.redhat.com/show_bug.cgi?id=1308771.
2016-02-22tree-wide: make ++/-- usage consistent WRT spacingVito Caputo
Throughout the tree there's spurious use of spaces separating ++ and -- operators from their respective operands. Make ++ and -- operator consistent with the majority of existing uses; discard the spaces.
2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
2016-01-13tree-wide: check if errno is greater then zeroZbigniew Jędrzejewski-Szmek
gcc is confused by the common idiom of return errno ? -errno : -ESOMETHING and thinks a positive value may be returned. Replace this condition with errno > 0 to help gcc and avoid many spurious warnings. I filed a gcc rfe a long time ago, but it hard to say if it will ever be implemented [1]. Both conventions were used in the codebase, this change makes things more consistent. This is a follow up to bcb161b0230f. [1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61846
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.

There are more than enough to deserve their own .c file, hence move them over.
2015-09-09locale: kill free_and_replace()Daniel Mack
That function really makes little sense, as the open-coded variant is much more readable. Also, if the 2nd argument is NULL, mfree() is a much better candidate. Convert the only users of this function in localed, and then remove it entirely.
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.
2015-08-30locale: add printf attribute to log_xkb()Cristian Rodríguez
2015-08-07strv: convert strv_split_quotes into a generic strv_split_extractRichard Maw
strv_split_extract is to strv_split_quotes as extract_first_word was to unquote_first_word. Now there's extract_first_word for extracting a single argument, extract_many_words for extracting a bounded number of arguments, and strv_split_extract for extracting an arbitrary number of arguments.
2015-08-05Merge branch 'hostnamectl-dot-v2'Zbigniew Jędrzejewski-Szmek
Manual merge of https://github.com/systemd/systemd/pull/751.
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.
2015-07-29tree-wide: port everything over to fflush_and_check()Lennart Poettering
Some places invoked fflush() directly with their own manual error checking, let's unify all that by using fflush_and_check(). This also unifies the general error paths of fflush()+rename() file writers.
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
2015-04-29sd-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().
2015-03-26util: rework word parsing and c unescaping codeLennart Poettering
When parsing words from input files, optionally automatically unescape the passed strings, controllable via a new flags parameter. Make use of this in tmpfiles, and port everything else over, too. This improves parsing quite a bit, since we no longer have to process the same string multiple times with different calls, where an earlier call might corrupt the input for a later call.
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.
2015-02-06localed: add LANGUAGE= fallback when LANG= is specifiedZbigniew Jędrzejewski-Szmek
For the entries listed in the first column of language-fallback-map, the entry from the second column will be used for LANGUAGE=, if LANGUAGE= is not explicitly specified. https://bugzilla.redhat.com/show_bug.cgi?id=624158
2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.
2014-12-28tmpfiles: add new line type 'v' for creating btrfs subvolumesLennart Poettering
2014-12-25localed: 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-localed" builds cleanly and works after this change.
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.
2014-12-03localed: log xkbcommon errorsJan Synacek
The errors are prefixed with "libxkbcommon" to provide some context, because they are quite confusing without it. With the prefix, we at least know where they come from.
2014-11-28treewide: yet more log_*_errno + return simplificationsMichal Schmidt
Using: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg; print;' $f done And a couple of manual whitespace fixups.
2014-11-28treewide: more log_*_errno() conversions, multiline callsMichal Schmidt
Basically: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/log_(debug|info|notice|warning|error|emergency)\("([^"]*)%s"([^;]*),\s*strerror\(-?([->a-zA-Z_]+)\)\);/log_\1_errno(\4, "\2%m"\3);/gms;print;' \ $f; done Plus manual indentation fixups.
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().
2014-11-25localed: verify xkb keymaps after pk-queriesDavid Herrmann
Make sure not to run xkb-keymap validation twice if pk-queries are used. Move it below pk-checks.
2014-11-24localed: validate xkb keymapsDavid Herrmann
Introduce a new optional dependency on libxkbcommon for systemd-localed. Whenever the x11 keymap settings are changed, use libxkbcommon to compile the keymap. If the compilation fails, print a warning so users will get notified. On compilation failure, we still update the keymap settings for now. This patch just introduces the xkbcommon infrastructure to have keymap validation in place. We can later decide if/how we want to enforce this.
2014-11-10strv: rework strv_split_quoted() to use unquote_first_word()Lennart Poettering
This should make the unquoting scheme a bit less naive.
2014-10-23mac: rename apis with mac_{selinux/smack}_ prefixWaLyong Cho
2014-09-23localed: rename write_data_x11 to x11_write_dataZbigniew Jędrzejewski-Szmek
Other functions in this file follow this pattern, we have vconsole_write_data and locale_write_data.
2014-09-03localed: check for partially matching converted keymapsZbigniew Jędrzejewski-Szmek
If a user specifies multiple X11 keymaps, with a (at least the first one) nonempty variant, and we don't match the whole combo, use a converted keymap which includes the variant in preference to the default, variantless, keymap. E.g.: We would convert X11 config "layout=fr variant=mac" to "fr-mac", but "layout=fr,us variant=mac," to "fr", because we don't have a converted keymap which would match "fr,us", and we don't have a legacy mapping for "fr,us". This is unexpected, and if we cannot match both, it is still better to match the primary mapping and use "fr-mac".
2014-09-03localed: introduce helper function to simplify matchingZbigniew Jędrzejewski-Szmek
2014-09-03localed: log locale/keymap changes in detailZbigniew Jędrzejewski-Szmek
Converting X11 to legacy keymaps and back is a fucking mess. Let's make it at least possible to request detailed logs of what is being changed and why (LOG_DEBUG level). At LOG_INFO level, we would log the requested change of X11 or console keymap, but not the resulting change after conversion to console or X11. Make sure that every change of configuration on disk has a matching line in the logs.
2014-09-03localed: remove free_and_copyZbigniew Jędrzejewski-Szmek
It was mostly a duplicate of free_and_strdup().
2014-09-03localed: double free in error path and modernizationZbigniew Jędrzejewski-Szmek
Very unlikely to trigger, but in principle strv_free could be called twice: once explictly, and once from cleanup.
2014-08-28locale: fix sending PropertiesChanged for x11 keymap changedDavid Herrmann
The sd_bus_emit_properties_changed() call for x11 keymap changes lacks commas.. whoops. Fix it! Now localed emits PropertiesChanged signals again.
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.
2014-08-15sd-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.
