2015-09-05sd-login: add new sd_pid_get_cgroup() APILennart Poettering
This adds a new sd_pid_get_cgroup() call to sd-login which may be used to query the control path of a process. This is useful for programs when making use of delegation units, in order to figure out which subtree has been delegated. In light of the unified control group hierarchy this is finally safe to do, hence let's add a proper API for it, to make it easier to use this.

2015-09-05NEWS: add entries for v226David Herrmann
Initial set of features for the upcoming v226 release next week. This is mostly about the unified cgroup hierarchy and DHCP.

2015-09-04networkd: adjust error codes for nonexisting DHCP dataMartin Pitt
Commit 0339cd770 changed libsystemd-network's error code for missing DHCP lease data from ENOENT to ENODATA. Adjust networkd accordingly. This fixes interfaces being stuck in "degraded/configuring" mode forever. https://github.com/systemd/systemd/issues/1147
2015-09-04tests: Skip tests which need to access /sys/fs/cgroup if that is not availableMartin Pitt
Commit efdb023 ("core: unified cgroup hierarchy support") introduced a new error ENOEXEC in cg_unified() if /sys/fs/cgroup/ is not available. Adjust the "skip" checks in various tests accordingly. Add a corresponding "skip" check to test-bus-creds as well, as sd_bus_creds_new_from_pid() now calls cg_unified() as well. This re-fixes "make check" in build chroots without /sys/fs/cgroup. https://github.com/systemd/systemd/issues/1132
2015-09-04hwdb: Add Thinkpad T550 / W550s to 70-pointingstick.hwdbHans de Goede
Like many other recent thinkpads the factory default pointingstick sensitivity on these devices is quite low, making the pointingstick very slow in moving the cursor. This extends the existing hwdb rules for tweaking the sensitivity to also apply to the T550 / W550s models. BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1200717

bus-proxy: increase NOFILE limit
2015-09-04Merge pull request #1141 from poettering/logind-fixesDaniel Mack
Various logind fixes
2015-09-04bus-proxy: increase NOFILE limitDavid Herrmann
The bus-proxy manages the kdbus connections of all users on the system (regarding the system bus), hence, it needs an elevated NOFILE. Otherwise, a single user can trigger ENFILE by opening NOFILE connections to the bus-proxy. Note that the bus-proxy still does per-user accounting, indirectly via the proxy/fake API of kdbus. Hence, the effective per-user limit is not raised by this. However, we now prevent one user from consuming the whole FD limit of the shared proxy. Also note that there is no *perfect* way to set this. The proxy is a shared object, so it needs a larger NOFILE limit than the highest limit of all users. This limit can be changed dynamically, though. Hence, we cannot protect against it. However, a raised NOFILE limit is a privilege, so we just treat it as such and basically allow these privileged users to be able to consume more resources than normal users (and, maybe, cause some limits to be exceeded by this). Right now, kdbus hard-codes 1024 max connections per user on each bus. However, we *must not* rely on this. This limits could be easily dropped entirely, as the NOFILE limit is a suitable limit on its on.

And not bool.

2015-09-04cgroups: delegation to unprivileged services is safe in the unified hierarchyLennart Poettering
Delegation to unpriviliged processes is safe in the unified hierarchy, hence allow it. This has the benefit of permitting "systemd --user" instances to further partition their resources between user services.
2015-09-04sd-login: rework error handlingLennart Poettering
Makre sure we always return sensible errors for the various, following the same rules, and document them in a comment in sd-login.c. Also, update all relevant man pages accordingly.
2015-09-04sd-event: make sure RT signals are not droppedLennart Poettering
RT signals operate in a queue, and we should be careful to never merge two queued signals into one. Hence, makes sure we only ever dequeue a single signal at a time and leave the remaining ones queued in the signalfd. In order to implement correct priorities for the signals introduce one signalfd per priority, so that we only process the highest priority signal at a time.
2015-09-04test: add one more test case for parse_pid()Lennart Poettering
2015-09-04nspawn: enable all controllers we can for the "payload" subcgroup we createLennart Poettering
In the unified hierarchy delegating controller access is safe, hence make sure to enable all controllers for the "payload" subcgroup if we create it, so that the container will have all controllers enabled the nspawn service itself has.
2015-09-04cgroup: always read the supported controllers from the root cgroup of the ↵Lennart Poettering
local container Otherwise we might end up thinking that we support more controllers than actually enabled for the container we are running in.

2015-09-04cgroup: make sure cg_is_empty_recursive() returns 1 for non-existing cgroupsLennart Poettering
Previously, on the legacy hierarchy a non-existing cgroup was considered identical to an empty one, but the unified hierarchy the check for a non-existing one returned ENOENT.
2015-09-04cgroup: when comparing agent paths, use path_equal()Lennart Poettering
After all a path is a path is a path and we should use path_equal() to comapre those.
2015-09-04audit: audit calls should return ENODATA when process are not in an audit ↵Lennart Poettering
session ENODATA is how we usually indicate such "missing info" cases, so we should do this here, too.
2015-09-04util: document why parse_uid() returns ENXIOLennart Poettering
parse_uid() returns EINVAL for invalid strings, but ENXIO for the (uid_t) -1 user ids in order to distinguish these two cases. Document this.
2015-09-04core: split up manager_get_unit_by_pid()Lennart Poettering
Let's move the actual cgroup part of it into a new separate function manager_get_unit_by_pid_cgroup(), and then make manager_get_unit_by_pid() just a wrapper that also checks the two pid hashmaps. Then, let's make sure the various calls that want to deliver events to the owners of a PID check both hashmaps and the cgroup and deliver the event to *each* of them. OTOH make sure bus calls like GetUnitByPID() continue to check the PID hashmaps first and the cgroup only as fallback.
2015-09-04cgroup: move controller to dirname translation into join_path_legacy()Lennart Poettering
Let's simplify things a bit.
2015-09-04util: add new uid_is_valid() callLennart Poettering
This simply factors out the uid validation checks from parse_uid() and uses them everywhere. This simply verifies that the passed UID is neither 64bit -1 nor 32bit -1.
2015-09-04macro: introduce new PID_TO_PTR macros and make use of themLennart Poettering
This adds a new PID_TO_PTR() macro, plus PTR_TO_PID() and makes use of it wherever we maintain processes in a hash table. Previously we sometimes used LONG_TO_PTR() and other times ULONG_TO_PTR() for that, hence let's make this more explicit and clean up things.
2015-09-04man: always use the same example in nss module documentationLennart Poettering
Show the same recommended example file in all three man pages, just highlight the different, relevant parts. This should be less confusing for users, and clarify what we actually recommend how /etc/nsswitch.conf is set up.

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.
