2015-08-24util: make machine_name_is_valid() a macro and move it to hostname-util.hLennart Poettering
As it turns out machine_name_is_valid() does the exact same thing as hostname_is_valid() these days, as it just invoked that and checked the name length was < 64. However, hostname_is_valid() checks the length against HOST_NAME_MAX anyway (which is 64 on Linux), hence any additional check is redundant. We hence replace machine_name_is_valid() by a macro that simply maps it to hostname_is_valid() but sets the allow_trailing_dot parameter to false. We also move this this call to hostname-util.h, to the same place as the hostname_is_valid() declaration.
2015-08-20import: don't create sparse tar archivesVincent Batts
Sparse archives are good for files like utmp/wtmp and journals, but it is still expenseive in having to read the files twice to archive them. Additionally there is a supportability issue as GNU sparse archives are not supported by many archive libraries and tooling.

2015-08-05hostname-util: add relax parameter to hostname_is_validZbigniew Jędrzejewski-Szmek
Tests are modified to check behaviour with relax and without relax. New tests are added for hostname_cleanup(). Tests are moved a new file (test-hostname-util) because there's now a bunch of them. New parameter is not used anywhere, except in tests, so there should be no observable change.
2015-07-31tree-wide: introduce mfree()David Herrmann
Pretty trivial helper which wraps free() but returns NULL, so we can simplify this: free(foobar); foobar = NULL; to this: foobar = mfree(foobar);
2015-07-24tree-wide: do not use _cleanup_free_ on const pointersDaniel Mack
free() cannot be used with const pointers. However, our _cleanup_free_ handler features cast logic that hides that qualifier, so we don't get a warning.
2015-07-03sd-bus: introduce new sd_bus_flush_close_unref() callLennart Poettering
sd_bus_flush_close_unref() is a call that simply combines sd_bus_flush() (which writes all unwritten messages out) + sd_bus_close() (which terminates the connection, releasing all unread messages) + sd_bus_unref() (which frees the connection). The combination of this call is used pretty frequently in systemd tools right before exiting, and should also be relevant for most external clients, and is hence useful to cover in a call of its own. Previously the combination of the three calls was already done in the _cleanup_bus_close_unref_ macro, but this was only available internally. Also see #327
2015-06-18import/pull: fix pulling by image digestPavel Odvody
When pulling by image digest the identifiers that were produced by parsing image digest were later overwritten by code parsing image tag. This resulted in invalid identifiers being used when contacting the remote endpoint, resulting in 404. Reported here: http://lists.freedesktop.org/archives/systemd-devel/2015-June/033039.html

2015-06-15everywhere: port everything to sigprocmask_many() and friendsLennart Poettering
This ports a lot of manual code over to sigprocmask_many() and friends. Also, we now consistly check for sigprocmask() failures with assert_se(), since the call cannot realistically fail unless there's a programming error. Also encloses a few sd_event_add_signal() calls with (void) when we ignore the return values for it knowingly.
2015-06-15util: when creating temporary file names, allow including extra id string in itLennart Poettering
This adds a "char *extra" parameter to tempfn_xxxxxx(), tempfn_random(), tempfn_ranomd_child(). If non-NULL this string is included in the middle of the newly created file name. This is useful for being able to distuingish the kind of temporary file when we see one. This also adds tests for the three call. For now, we don't make use of this at all, but port all users over.
2015-06-10util: introduce CMSG_FOREACH() macro and make use of it everywhereLennart Poettering
It's only marginally shorter then the usual for() loop, but certainly more readable.

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.

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.

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.

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.

2015-02-24importd: 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.

2015-02-18shared: 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.
