2015-05-05shared/utmp-wtmp: fix copy/paste errorMichael Olbrich
2015-05-05lockfile-util.[ch]: Split out from util.[ch]Colin Walters
Continuing the general trend of splitting up util.[ch]. I specifically want to reuse this code in https://github.com/GNOME/libglnx and having it split up will make future copy-pasting easier.
2015-05-05Fix permissions on /run/systemd/nspawn/locksSeth Jennings
machined is getting an EACCES when trying to create the lock file for images because the mode on /run/systemd/nspawn/locks is 0600. mkdir("/run/systemd/nspawn/locks", 0600) = -1 EEXIST (File exists) stat("/run/systemd/nspawn/locks", {st_mode=S_IFDIR|0600, st_size=40, ...}) = 0 open("/run/systemd/nspawn/locks/inode-41:256", O_RDWR|O_CREAT|O_NOCTTY|O_NOFOLLOW|O_CLOEXEC, 0600) = -1 EACCES (Permission denied) This commit adjusts the mode to 0700 to correct the issue.
2015-05-05core: be more strict when manipulating slices names and unescaping paths ↵Lennart Poettering
from unit names Let's better be safe then sorry.
2015-05-05core: rework unit name validation and manipulation logicLennart Poettering
A variety of changes: - Make sure all our calls distuingish OOM from other errors if OOM is not the only error possible. - Be much stricter when parsing escaped paths, do not accept trailing or leading escaped slashes. - Change unit validation to take a bit mask for allowing plain names, instance names or template names or an combination thereof. - Refuse manipulating invalid unit name
2015-05-05util: be a bit safer in path_is_safe()Lennart Poettering
We should be more strict when verifying paths with path_is_safe() for potentially dangerous constructs, and that includes lengths of PATH_MAX-1 and larger. Be more accurate here.
2015-05-05cgroup-util: be more strict when processing slice unit namesLennart Poettering
2015-05-04generators: rename add_{root,usr}_mount to add_{sysroot,sysroot_usr}_mountZbigniew Jędrzejewski-Szmek
This makes it obvious that those functions are only usable in the initramfs. Also, add a warning when noauto, nofail, or automount is used for the root fs, instead of silently ignoring. Using those options would be a sign of significant misconfiguration, and if we bother to check for them, than let's go all the way and complain. Other various small cleanups and reformattings elsewhere.
2015-04-30core: catch some special cases in cg_slice_to_path()Lennart Poettering
2015-04-30sd-bus,sd-login: add api for querying the slice within the the user systemd ↵Lennart Poettering
instance of a process units are organized in slice trees, not only for the system instance, but also for user systemd instances, expose this properly.
2015-04-30core: rework cgroup path parse logicLennart Poettering
Various cleanups, be stricter when parsing unit paths. Most importantly: return the root slice "-.slice" when asked for slice of paths that contain no slice component.
2015-04-29sd-bus: properly handle creds that are known but undefined for a processLennart Poettering
A number of fields do not apply to all processes, including: there a processes without a controlling tty, without parent process, without service, user services or session. To distuingish these cases from the case where we simply don't have the data, always return ENXIO for them, while returning ENODATA for the case where we really lack the information. Also update the credentials dumping code to show this properly. Fields that are known but do not apply are now shown as "n/a". Note that this also changes some of the calls in process-util.c and cgroup-util.c to return ENXIO for these cases.

2015-04-24shared/utmp-wtmp: add parameter for origin tty and callback userdataDaniel Mack
Instead of looking up the tty from STDIN, let utmp_wall() take an argument to specify an origin tty for the wall message. Only if that argument is NULL do the STDIN lookup. Also add an void *userdata argument that is handed back to the callback function.

test for mount points It's a very recent kernel addition, but certainly makes sense to support.
2015-04-23util: Fix assertion in split() on missing 'Martin Pitt
When parsing a unit with a trailing slash after an escaped line break, like ExecStart=/bin/echo 'foo \ bar' the split() function (through config_parse()) asserted and crashed pid 1: Assertion 'current[*l + 1] == quotechars[0]' failed at ../src/shared/util.c:583, function split(). Aborting. Fix this by returning an error in this case ("trailing garbage"). Add corresponding test case. Also fix the missing "unit" argument of config_parse_exec() in the comment. https://launchpad.net/bugs/1447243
2015-04-22journalctl: rework code that checks whether we have access to /var/log/journalLennart Poettering
- fix some memory leaks on error conditions - handle all error cases properly, and log about failures - move HAVE_ACL and no-HAVE_ACL code closer to each other
2015-04-22btrfs-util: support recursive removal of read-only subvolumesLennart Poettering
When deleting a read-only subsvolume with a sub-subvolume, we need to mark it writable first, otherwise the removal will not work.
2015-04-22btrfs-util: fix creating recursive read-only snapshotsLennart Poettering
When creating recursive read-only snapshots we need to mark the snapshot writable immediately before creating subsnapshots within it, otherwise the operation for it will fail.
2015-04-22btrfs-util: be more careful when invoking btrfs file system ioctlsLennart Poettering
If we get passed an fd that does not refer to a regular file or directory, we should not issue btrfs ioctls on it, since it might end up in a device driver or similar (note that DRM for example uses the same ioctl numbers as some file system ioctls). Hence, let's make sure to always check if something is a regular file or directory, or is on btrfs before invoking the respective ioctls. It's better to be safe than sorry.
2015-04-22btrfs-util: introduce btrfs_is_filesystem() and make use of it where appropriateLennart Poettering
Let's unify the code that checks whether an fd is on btrfs a bit. (Also, rename btrfs_is_snapshot() to btrfs_is_subvol(), since that's usually how this is referred to in our code)
2015-04-22util: make sure fd refers to regular file or directory when applying file ↵Lennart Poettering
attributes Before invoking file system ioctls we need to make sure that the specified fd actually refers to a file system object, and not a device node or similar. Otherwise we might by accident invoke unrelated device driver ioctls. For example, DRM ioctls use the same ioctl numbers as the various file system ioctls.

2015-04-16shared: move assert_return_errno() from libudevTom Gundersen
This should not be used for any new code, as we don't set errno in new code, but there are several legacy users, so let's keep it in shared.

2015-04-11bus: implement bus_label_unescape_n()David Herrmann
This is like bus_label_unescape() but takes a maximum length instead of relying on NULL-terminated strings. This is highly useful to unescape labels that are not at the end of a path.
2015-04-11hashmap: return NULL from destructorDavid Herrmann
We _always_ return NULL from destructors to allow direct assignments to the variable holding the object. Especially on hashmaps, which treat NULL as empty hashmap, this is pretty neat.

systemctl and logind were unconditionally using functions that were not compiled on non-EFI systems. Add stubs returning -EOPNOTSUPP to fix compile again.
2015-04-10shared: efivars - is_efi_*() returns bool instead of intTom Gundersen
There was a bug where is_efi_*() could return a negative error value, which would be treated as 'true', just make this a bool in the helper library to avoid the problem.
