2015-06-10tree-wide: whenever we fork off a foreign child process reset signal ↵Lennart Poettering
mask/handlers Also, when the child is potentially long-running make sure to set a death signal. Also, ignore the result of the reset operations explicitly by casting them to (void).
2015-05-29util: split out signal-util.[ch] from util.[ch]Lennart Poettering
No functional changes.
2015-05-25import: dkr - avoid NULL-pointer dereferenceTom Gundersen
A malformed manifest could in principle cause a NULL pointer dereference of. Check for this and fail early. Fixes CID 1299642.

2015-04-29sd-bus: allow passing NULL as bus parameter to sd_bus_send()Lennart Poettering
If NULL is specified for the bus it is now automatically derived from the passed in message. This commit also changes a number of invocations of sd_bus_send() to make use of this.
2015-04-29sd-bus: drop bus parameter from message callback prototypeLennart Poettering
This should simplify the prototype a bit. The bus parameter is redundant in most cases, and in the few where it matters it can be derived from the message via sd_bus_message_get_bus().

2015-04-07util: rework cunescape(), improve error handlingLennart Poettering
Change cunescape() to return a normal error code, so that we can distuingish OOM errors from parse errors. This also adds a flags parameter to control whether "relaxed" or normal parsing shall be done. If set no parse failures are generated, and the only reason why cunescape() can fail is OOM.
2015-04-06btrfs: add support for recursive btrfs snapshottingLennart Poettering

2015-03-13tree-wide: there is no ENOTSUP on linuxDavid Herrmann
Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.
2015-03-10util: add rename_noreplaceAlban Crequy
renameat2() exists since Linux 3.15 but btrfs support for the flag RENAME_NOREPLACE was added later. This patch implements a fallback when renameat2() returns EINVAL. EINVAL is the error returned when the filesystem does not support one of the flags.
2015-03-10shared: the btrfs quota field is called "referenced" not "referred"Lennart Poettering
2015-03-09importd: add API for exporting container/VM imagesLennart Poettering
Also, expose it in machinectl.
2015-03-05importd: add new bus calls for importing local tar and raw imagesLennart Poettering
This also adds "machinectl import-raw" and "machinectl import-tar" to wrap these new bus calls. THe commands basically do for local files that "machinectl pull-raw" and friends do for remote files.

import and pull calls
2015-03-05import: rename download code from "import" to "pull"Lennart Poettering
That way we can call the code for local container/VM imports "import" without confusion.
2015-03-03importd: automatically grow /var/lib/machines/ loopback filesystem during ↵Lennart Poettering
downloads If /var/lib/machines is mounted as btrfs loopback file system in /var/lib/machines.raw with this change we automatically grow the file system as it fills up. After each 10M we write to it during imports, we check the free disk space, and if the fill level grows beyond 66% we increase the size of the file system to 3x the fill level (thus lowering it to 33%).
2015-03-02import: add support for gpg2 for verifying imported imagesLennart Poettering
gpg2 insists on created a trust db even if we tun off all trust db support. Hence create a temporary home where the trust db is placed, and remove it after use.
2015-03-02machined: also set up /var/lib/machines as btrfs, if "machinectl set-limit" ↵Lennart Poettering

2015-03-02importd: split out setup logic for /var/lib/machines into its own API fileLennart Poettering
2015-02-24importd: enable btrfs quota in /var/lib/machines, if necessaryLennart Poettering
2015-02-24importd: create a loopback btrfs file system for /var/lib/machines, if necessaryLennart Poettering
When manipulating container and VM images we need efficient and atomic directory snapshots and file copies, as well as disk quota. btrfs provides this, legacy file systems do not. Hence, implicitly create a loopback file system in /var/lib/machines.raw and mount it to /var/lib/machines, if that directory is not on btrfs anyway. This is done implicitly and transparently the first time the user invokes "machinectl import-xyz". This allows us to take benefit of btrfs features for container management without actually having the rest of the system use btrfs. The loopback is sized 500M initially. Patches to grow it dynamically are to follow.
2015-02-24import: print nice warning if we need btrfs but /var/lib/machines is not btrfsLennart Poettering
2015-02-18shared: introduce cmsg_close_all() callLennart Poettering
The call iterates through cmsg list and closes all fds passed via SCM_RIGHTS. This patch also ensures the call is used wherever appropriate, where we might get spurious fds sent and we should better close them, then leave them lying around.
2015-02-18logind: open up most bus calls for unpriviliged processes, using PolicyKitLennart Poettering
Also, allow clients to alter their own objects without any further priviliges. i.e. this allows clients to kill and lock their own sessions without involving PK.

2015-02-05networkd: exit on idleTom Gundersen
We will be woken up on rtnl or dbus activity, so let's just quit if some time has passed and that is the only thing that can happen. Note that we will always stay around if we expect network activity (e.g. DHCP is enabled), as we are not restarted on that.
2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.

2015-01-23importd: when listing transfers, show progress percentageLennart Poettering
With this change the pull protocol implementation processes will pass progress data to importd which then passes this information on via the bus. We use sd_notify() as generic transport for this communication, making importd listen to them, while matching the incoming messages to the right transfer.
