2015-10-24path-util: rework find_binary(), fsck_exists() and mkfs_exists()Lennart Poettering
Modernize the code a bit: - Get rid of FOREACH_WORD_SEPARATOR() loop in favour of a extract_first_word() loop. - Remove find_binary()'s "local" flag. It's not reasonably possible to look for binaries on remote systems, we hence should not pretend we could. - When we cannot find a suitable binary, return the last error returned from access() rather than ENOENT unconditionally. - Rework fsck_exists() and mkfs_exists() to return 1 on success, 0 if the implementation is missing and negative on real errors. This is more like we do it in other functions. - Make sure we also detect direct fsck symlinks to "true", rather than just absolute ones to /bin/true.
2015-10-22import: when downloading images, create a subtree quota group for themLennart Poettering
2015-10-22btrfs: beef-up btrfs support with a limited understanding of quotaLennart Poettering
With this change we understand more than just leaf quota groups for btrfs file systems. Specifically: - When we create a subvolume we can now optionally add the new subvolume to all qgroups its parent subvolume was member of too. Alternatively it is also possible to insert an intermediary quota group between the parent's qgroups and the subvolume's leaf qgroup, which is useful for a concept of "subtree" qgroups, that contain a subvolume and all its children. - The remove logic for subvolumes has been updated to optionally remove any leaf qgroups or "subtree" qgroups, following the logic above. - The snapshot logic for subvolumes has been updated to replicate the original qgroup setup of the source, if it follows the "subtree" design described above. It will not cover qgroup setups that introduce arbitrary qgroups, especially those orthogonal to the subvolume hierarchy. This also tries to be more graceful when setting up /var/lib/machines as btrfs. For example, if mkfs.btrfs is missing we don't even try to set it up as loopback device. Fixes #1559 Fixes #1129

See https://github.com/systemd/systemd/pull/1534#commitcomment-13744013 Actually, thinking about this, maybe it would be nicer to actually look for "Limit" in the string rather than chopping off a "Default".... Sounds more generic...

2015-10-07machinectl: fix race when opening new shells with "machinectl shell"Lennart Poettering
Previously, we'd allocate the TTY, spawn a service on it, but immediately start processing the TTY and forwarding it to whatever the commnd was started on. This is however problematic, as the TTY might get actually opened only much later by the service. We'll hence first get EIOs on the master as the other side is still closed, and hence considered it hung up and terminated the session. With this change we add a flag to the pty forwarding logic: PTY_FORWARD_IGNORE_INITIAL_VHANGUP. If set, we'll ignore all hangups (i.e. EIOs) on the master PTY until the first byte is successfully read. From that point on we consider a hangup/EIO a regular connection termination. This way, we handle the race: when we get EIO initially we'll ignore it, until the connection is properly set up, at which time we start honouring it.
2015-10-07ask-password: add support for caching passwords in the kernel keyringLennart Poettering
This adds support for caching harddisk passwords in the kernel keyring if it is available, thus supporting caching without Plymouth being around. This is also useful for hooking up "gdm-auto-login" with the collected boot-time harddisk password, in order to support gnome keyring passphrase unlocking via the HDD password, if it is the same. Any passwords added to the kernel keyring this way have a timeout of 2.5min at which time they are purged from the kernel.
2015-10-06ask-password: various modernizationsLennart Poettering
Primarily clean-up error logging: log either all or no error messages in the various functions. Mostly this means the actual password querying calls no longer will log on their own, but the callers have to do so. Contains various other fixes too, for example ports some code over to use the clean-up macro. Should contain no functional changes.
2015-10-05hashmap: hash_funcs - make inputs unambiguousTom Gundersen
Make sure all variable-length inputs are properly terminated or that their length is encoded in some way. This avoids ambiguity of adjacent inputs. E.g., in case of a hash function taking two strings, compressing "ab" followed by "c" is now distinct from "a" followed by "bc".
2015-10-05hashmap: refactor hash_funcTom Gundersen
All our hash functions are based on siphash24(), factor out siphash_init() and siphash24_finalize() and pass the siphash state to the hash functions rather than the hash key. This simplifies the hash functions, and in particular makes composition simpler as calling siphash24_compress() repeatedly on separate chunks of input has the same effect as first concatenating the input and then calling siphash23_compress() on the result.

2015-09-30tree-wide: clean up log_syntax() usageLennart Poettering
- Rely everywhere that we use abs() on the error code passed in anyway, thus don't need to explicitly negate what we pass in - Never attach synthetic error number information to log messages. Only log about errors we *receive* with the error number we got there, don't log any synthetic error, that don#t even propagate, but just eat up. - Be more careful with attaching exactly the error we get, instead of errno or unrelated errors randomly. - Fix one occasion where the error number and line number got swapped. - Make sure we never tape over OOM issues, or inability to resolve specifiers

2015-09-30fileio: make get_status_field() more genericAaro Koskinen
All users of get_status_field() expect the field pattern to occur in the beginning of a line, and the delimiter is ':'. Hardcode this into the function, and also skip any whitespace before ':' to support fields in files like /proc/cpuinfo. Add support for returning the full field value (currently stops on first whitespace). Rename the function so it's easier to ensure all callers switch to new semantics.

2015-09-29bus-util: rename bus_open_transport() to bus_connect_transport()Lennart Poettering
In sd-bus, the sd_bus_open_xyz() family of calls allocates a new bus, while sd_bus_default_xyz() family tries to reuse the thread's default bus. bus_open_transport() sometimes internally uses the former, sometimes the latter family, but suggests it only calls the former via its name. Hence, let's avoid this confusion, and generically rename the call to bus_connect_transport(). Similar for all related calls. And while we are at it, also change cgls + cgtop to do direct systemd connections where possible, since all they do is talk to systemd itself.

2015-09-11core: refactor cpu shares/blockio weight cgroup logicLennart Poettering
Let's stop using the "unsigned long" type for weights/shares, and let's just use uint64_t for this, as that's what we expose on the bus. Unify parsers, and always validate the range for these fields. Correct the default blockio weight to 500, since that's what the kernel actually uses. When parsing the weight/shares settings from unit files accept the empty string as a way to reset the weight/shares value. When getting it via the bus, uniformly map (uint64_t) -1 to unset. Open up StartupCPUShares= and StartupBlockIOWeight= to transient units.

core: add support for the "pids" cgroup controller
2015-09-10core: add support for the "pids" cgroup controllerLennart Poettering
This adds support for the new "pids" cgroup controller of 4.3 kernels. It allows accounting the number of tasks in a cgroup and enforcing limits on it. This adds two new setting TasksAccounting= and TasksMax= to each unit, as well as a gloabl option DefaultTasksAccounting=. This also updated "cgtop" to optionally make use of the new kernel-provided accounting. systemctl has been updated to show the number of tasks for each service if it is available. This patch also adds correct support for undoing memory limits for units using a MemoryLimit=infinity syntax. We do the same for TasksMax= now and hence keep things in sync here.
