2016-02-01core: fix support for transient resource limit propertiesLennart Poettering
Make sure we can properly process resource limit properties. Specifically, allow transient configuration of both the soft and hard limit, the same way from the unit files. Previously, only the the hard rlimits could be configured but they'd implicitly spill into the soft hard rlimits. This also updates the client-side code to be able to parse hard/soft resource limit specifications. Since we need to serialize two properties in bus_append_unit_property_assignment() now, the marshalling of the container around it is now moved into the function itself. This has the benefit of shortening the calling code. As a side effect this now beefs up the rlimit parser of "systemctl set-property" to understand time and disk sizes where that's appropriate.

2016-01-12capabilities: keep bounding set in non-inverted format.Ismo Puustinen
Change the capability bounding set parser and logic so that the bounding set is kept as a positive set internally. This means that the set reflects those capabilities that we want to keep instead of drop.

2015-12-28nspawn: userns and unified cgroup: chown cgroup.eventsAlban Crequy
When starting a container in a new user namespace, systemd-nspawn chowns the cgroup knob files so they are usable by the container. But the cgroup knob file "cgroup.events" was missing. This file exists when the unified hierarchy is used.

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.

2015-11-16siphash24: let siphash24_finalize() and siphash24() return the result directlyDaniel Mack
Rather than passing a pointer to return the result, return it directly from the function calls. Also, return the result in native endianess, and let the callers care about the conversion. For hash tables and bloom filters, we don't care, but in order to keep MAC addresses and DHCP client IDs stable, we explicitly convert to LE.

2015-11-16siphash24: change result argument to uint64_tMartin Pitt
Change the "out" parameter from uint8_t[8] to uint64_t. On architectures which enforce pointer alignment this fixes crashes when we previously cast an unaligned array to uint64_t*, and on others this should at least improve performance as the compiler now aligns these properly. This also simplifies the code in most cases by getting rid of typecasts. The only place which we can't change is struct duid's en.id, as that is _packed_ and public API, so we can't enforce alignment of the "id" field and have to use memcpy instead.

2015-11-12nspawn: add new --network-veth-extra= switch for defining additional veth linksLennart Poettering
The new switch operates like --network-veth, but may be specified multiple times (to define multiple link pairs) and allows flexible definition of the interface names. This is an independent reimplementation of #1678, but defines different semantics, keeping the behaviour completely independent of --network-veth. It also comes will full hook-up for .nspawn files, and the matching documentation.

2015-11-09nspawn: support custom container service nameIago López Galeiras
We were hardcoding "systemd-nspawn" as the value of the $container env variable and "nspawn" as the service string in machined registration. This commit allows the user to configure it by setting the $SYSTEMD_NSPAWN_CONTAINER_SERVICE env variable when calling systemd-nspawn. If $SYSTEMD_NSPAWN_CONTAINER_SERVICE is not set, we use the string "systemd-nspawn" for both, fixing the previous inconsistency.

Use the "return log_error_errno(...)" idiom to have fewer curly braces. The last hunk also fixes the return value of setup_journal(), but the fix has no practical effect.

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.

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.

2015-10-24util-lib: get_current_dir_name() can return errors other than ENOMEMLennart Poettering
get_current_dir_name() can return a variety of errors, not just ENOMEM, hence don't blindly turn its errors to ENOMEM, but return correct errors in path_make_absolute_cwd(). This trickles down into a couple of other functions, some of which receive unrelated minor fixes too with this commit.
