2016-01-25logind,machined: bump TasksMax=Lennart Poettering
Issue #2388 suggests the current TasksMax= setting for user processes is to low. Bump it to 12K. Also, bump the container TasksMax= from 8K to 16K, so that it remains higher than the one for user processes. (Compare: the kernel default limit for processes system-wide is 32K). Fixes #2388
2016-01-20basic/terminal-util: introduce SYSTEMD_COLORS environment variableJan Synacek
... to determine if color output should be enabled. If the variable is not set, fall back to using on_tty(). Also, rewrite existing code to use colors_enabled() where appropriate.
2016-01-18logind: simplify job variable handlingZbigniew Jędrzejewski-Szmek
manager_{start,stop}_{slice,scope,unit} functions had an optional job output parameter. But all callers specified job, so make the parameter mandatory, add asserts. Also extract common job variable handling to a helper function to avoid duplication. Avoids gcc warning about job being unitialized.
2016-01-18logind: do not use an uninitialized variableZbigniew Jędrzejewski-Szmek
We requested various fields using SD_BUS_CREDS_AUGMENT but at least sd_bus_creds_get_tty can fail with ENXIO, not setting the output variable.
2016-01-13tree-wide: check if errno is greater than zero (2)Zbigniew Jędrzejewski-Szmek
Compare errno with zero in a way that tells gcc that (if the condition is true) errno is positive.
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.

2015-11-16login: ignore JobRemoved of old jobsDavid Herrmann
If we requeue jobs, we are no longer interested in old jobs. Hence, we better ignore any JobRemoved signals for old jobs and concentrate on our replacements.
2015-11-16login: make sure to replace existing unitsDavid Herrmann
When queuing unit jobs, we should rather replace existing units than fail. This is especially important when we queued a user-shutdown and a new login is encountered. In this case, we better raplce the shutdown jobs. systemd takes care of everything else.
2015-11-16login: fix re-use of usersDavid Herrmann
If the last reference to a user is released, we queue stop-jobs for the user-service and slice. Only once those are finished, we drop the user-object. However, if a new session is opened before the user object is fully dropped, we currently incorrectly re-use the object. This has the effect, that we get stale sessions without a valid "systemd --user" instance. Fix this by properly allowing user_start() to be called, even if user->stopping is true.
2015-11-16login: group static fields in "struct User"David Herrmann
Make sure to put static fields together in "struct User". This makes it easier to figure out the lifetime of each field.
2015-11-16login: make user->service staticDavid Herrmann
Just like user->slice, there is no reason to store the unit name in /run, nor should we allocate it dynamically on job instantiation/removal. Just keep it statically around at all times and rely on user->started || user->stopping to figure out whether the unit exists or not.
2015-11-16login: make user_new() and user_free() follow coding-styleDavid Herrmann
Few changes to user_new() and user_free(): - Use _cleanup_(user_freep) in constructor - return 'int' from user_new() - make user_free() deal with partially initialized objects - keep reverse-order in user_free() compared to user_new() - make user_free() return NULL - make user_free() accept NULL as no-op
2015-11-16login: keep user->slice constantDavid Herrmann
Currently, we allocate user->slice when starting a slice, but we never release it. This is incompatible if we want to re-use a user object once it was stopped. Hence, make sure user->slice is allocated statically on the user object and use "u->started || u->stopping" as an indication whether the slice is actually available on pid1 or not.
2015-11-16login: simply XDG_RUNTIME_DIR managementDavid Herrmann
Lets not pretend we support changing XDG_RUNTIME_DIR via logind state files. There is no reason to ever write the string into /run, as we allocate it statically based on the UID, anyway. Lets stop that and just allocate the runtime_path in "struct User" at all times. We keep writing it into the /run state to make sure pam_systemd of previous installs can still read it. However, pam_systemd is now fixed to allocate it statically as well, so we can safely remove that some time in the future. Last but not least: If software depends on systemd, they're more than free to assume /run/user/$uid is their runtime dir. Lets not require sane applications to query the environment to get their runtime dir. As long as applications know their login-UID, they should be safe to deduce the runtime dir.

2015-11-13logind: add a new UserTasksMax= setting to logind.confLennart Poettering
This new setting configures the TasksMax= field for the slice objects we create for each user. This alters logind to create the slice unit as transient unit explicitly instead of relying on implicit generation of slice units by simply starting them. This also enables us to set a friendly description for slice units that way.
2015-11-13logind: don't assert if the slice is missingLennart Poettering
After all, we don't actually really need the slice to work, it's just nice to have it.
2015-11-10defs: rework CONF_DIRS_NULSTR() macroLennart Poettering
The macro is generically useful for putting together search paths, hence let's make it truly generic, by dropping the implicit ".d" appending it does, and leave that to the caller. Also rename it from CONF_DIRS_NULSTR() to CONF_PATHS_NULSTR(), since it's not strictly about dirs that way, but any kind of file system path. Also, mark CONF_DIR_SPLIT_USR() as internal macro by renaming it to _CONF_PATHS_SPLIT_USR() so that the leading underscore indicates that it's internal.

2015-11-03util-lib: move CONF_DIRS_NULSTR definition to def.hLennart Poettering
After all, this is not some compiler or C magic, but something very specific to how systemd works, hence let's move it into def.h, and out of macro.h

capability-util.[ch] The files are named too generically, so that they might conflict with the upstream project headers. Hence, let's add a "-util" suffix, to clarify that this are just our utility headers and not any official upstream headers.

So far we had two pretty much identical calls in user-util.[ch]: lookup_uid() and uid_to_name(). Get rid of the former, in favour of the latter, and while we are at it, rewrite it, to use getpwuid_r() correctly, inside an allocation loop, as POSIX intended.

2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
