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: 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.
2015-11-13udev/path_id: improve and enhance bus detection for Linux on z SystemsLiu Yuan Yuan
Improve and enhance the path_id udev builtin to correctly handle bus' available on Linux on z Systems (s390). Previously, the CCW bus and, in particular, any FCP devices on it, have been treated separately. This commit integrates the CCW bus into the device chain loop. FCP devices and their associated SCSI disks are now handled through the common SCSI handling functions in path_id. This implies also a change in the naming of the symbolic links created by udev. So any backports of this commit to existing Linux distribution must be done with care. If a backport is required, a udev rule must be created to also create the "old-style" symbolic links. Apart from the CCW bus, this commit adds bus support for the: - ccwgroup bus which manages network devices, and - ap bus which manages cryptographic adapters - iucv bus which manages IUCV devices on z/VM

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.

2015-10-14keymap: Drop keyboard-keys-to-name.hMartin Pitt
We don't use that anywhere any more. With the introduction of alias names it also is not a proper mapping any more as several keys (e. g. KEY_COFFEE and KEY_SCREENLOCK) have the same numerical mapping.
2015-10-05document ability to disable MACAddressPolicyJacob Keller
While it is currently possible to either not set MACAddressPolicy or set it to a value different from "persistent" or "random", it is not obvious that a user can do so. Add a policy, "none", which simply retains kernel MAC addresses (same as not filling in the policy at all) and document it so that users are aware of this setting.

This seems to be an oversight from: 707b66c66381c899d7ef640e158ffdd5bcff4deb We have to return ENODATA instead of ENOENT if a requested entry is non-present. Also fix the call-site in udev to check for these errors.

2015-09-02udev: net_id - support predictable ifnames on virtio busesTom Gundersen
Virtio buses are undeterministically enumerated, so we cannot use them as a basis for deterministic naming (see bf81e792f3c0). However, we are guaranteed that there is only ever one virtio bus for every parent device, so we can simply skip over the virtio buses when naming the devices.
