2015-11-25dns-domain: rework dns_label_escape() to not imply memory allocationLennart Poettering
The new dns_label_escape() call now operates on a buffer passed in, similar to dns_label_unescape(). This should make decoding a bit faster, and nicer.
2015-11-25dns-domain: change dns_srv_type_is_valid() return value to boolLennart Poettering
For similar reasons as dns_name_is_root() got changed in the previous commit.
2015-11-25dns-domain: simplify dns_name_is_root() and dns_name_is_single_label()Lennart Poettering
Let's change the return value to bool. If we encounter an error while parsing, return "false" instead of the actual parsing error, after all the specified hostname does not qualify for what the function is supposed to test. Dealing with the additional error codes was always cumbersome, and easily misused, like for example in the DHCP code. Let's also rename the functions from dns_name_root() to dns_name_is_root(), to indicate that this function checks something and returns a bool. Similar for dns_name_is_signal_label().

2015-11-24resolved: implement client-side DNAME resolutionLennart Poettering
Most servers apparently always implicitly convert DNAME to CNAME, but some servers don't, hence implement this properly, as this is required by edns0.
2015-11-23dns-domain: add calls to join/split SRV/DNS-SD service domainsLennart Poettering
This adds dns_service_join() and dns_service_split() which may be used to concatenate a DNS-SD service name, am SRV service type string, and a domain name into a full resolvable DNS domain name string. If the service name is specified as NULL, only the type and domain are appended, to implement classic, non-DNS-SD SRV lookups. The reverse is dns_service_split() which takes the full name, and split it into the three components again.

Remove support for RequiresOverridable= and RequisiteOverridable=
2015-11-12generator: order initrd fsck-root after local-fs-preMichael Marineau
The initrd version of systemd-fsck-root.service must wait for local-fs-pre.target just like systemd-fsck@.service to prevent modifications to the filesystem prior to resuming from hibernation. As-is my laptop routinely fails to resume due to fsck errors. The rest of the time it is probably silently corrupting the filesystem. Unlike normal boot, in the initrd systemd-fsck-root.service has no special significance so it needs to be kept in sync with systemd-fsck@.service. The name systemd-fsck-root.service is only used to preserve state across switch-root.
2015-11-12core: remove support for RequiresOverridable= and RequisiteOverridable=Lennart Poettering
As discussed at systemd.conf 2015 and on also raised on the ML: http://lists.freedesktop.org/archives/systemd-devel/2015-November/034880.html This removes the two XyzOverridable= unit dependencies, that were basically never used, and do not enhance user experience in any way. Most folks looking for the functionality this provides probably opt for the "ignore-dependencies" job mode, and that's probably a good idea. Hence, let's simplify systemd's dependency engine and remove these two dependency types (and their inverses). The unit file parser and the dbus property parser will now redirect the settings/properties to result in an equivalent non-overridable dependency. In the case of the unit file parser we generate a warning, to inform the user. The dbus properties for this unit type stay available on the unit objects, but they are now hidden from usual introspection and will always return the empty list when queried. This should provide enough compatibility for the few unit files that actually ever made use of this.
2015-11-12core: simplify handling of %u, %U, %s and %h unit file specifiersLennart Poettering
Previously, the %u, %U, %s and %h specifiers would resolve to the user name, numeric user ID, shell and home directory of the user configured in the User= setting of a unit file, or the user of the manager instance if no User= setting was configured. That at least was the theory. In real-life this was not ever actually useful: - For the systemd --user instance it made no sense to ever set User=, since the instance runs in user context after all, and hence the privileges to change user IDs don't even exist. The four specifiers were actually not useful at all in this case. - For the systemd --system instance we did not allow any resolving that would require NSS. Hence, %s and %h were not supported, unless User=root was set, in which case they would be hardcoded to /bin/sh and /root, to avoid NSS. Then, %u would actually resolve to whatever was set with User=, but %U would only resolve to the numeric UID of that setting if the User= was specified in numeric form, or happened to be root (in which case 0 was hardcoded as mapping). Two of the specifiers are entirely useless in this case, one is realistically also useless, and one is pretty pointless. - Resolving of these settings would only happen if User= was actually set *before* the specifiers where resolved. This behaviour was undocumented and is really ugly, as specifiers should actually be considered something that applies to the whole file equally, independently of order... With this change, %u, %U, %s and %h are drastically simplified: they now always refer to the user that is running the service instance, and the user configured in the unit file is irrelevant. For the system instance of systemd this means they always resolve to "root", "0", "/bin/sh" and "/root", thus avoiding NSS. For the user instance, to the data for the specific user. The new behaviour is identical to the old behaviour in all --user cases and for all units that have no User= set (or set to "0" or "root").
2015-11-12install: follow unit file symlinks in /usr, but not /etc when looking for ↵Lennart Poettering
[Install] data Some distributions use alias unit files via symlinks in /usr to cover for legacy service names. With this change we'll allow "systemctl enable" on such aliases. Previously, our rule was that symlinks are user configuration that "systemctl enable" + "systemctl disable" creates and removes, while unit files is where the instructions to do so are store. As a result of the rule we'd never read install information through symlinks, since that would mix enablement state with installation instructions. Now, the new rule is that only symlinks inside of /etc are configuration. Unit files, and symlinks in /usr are now valid for installation instructions. This patch is quite a rework of the whole install logic, and makes the following addional changes: - Adds a complete test "test-instal-root" that tests the install logic pretty comprehensively. - Never uses canonicalize_file_name(), because that's incompatible with operation relative to a specific root directory. - unit_file_get_state() is reworked to return a proper error, and returns the state in a call-by-ref parameter. This cleans up confusion between the enum type and errno-like errors. - The new logic puts a limit on how long to follow unit file symlinks: it will do so only for 64 steps at max. - The InstallContext object's fields are renamed to will_process and has_processed (will_install and has_installed) since they are also used for deinstallation and all kinds of other operations. - The root directory is always verified before use. - install.c is reordered to place the exported functions together. - Stricter rules are followed when traversing symlinks: the unit suffix must say identical, and it's not allowed to link between regular units and templated units. - Various modernizations - The "invalid" unit file state has been renamed to "bad", in order to avoid confusion between UNIT_FILE_INVALID and _UNIT_FILE_STATE_INVALID. Given that the state should normally not be seen and is not documented this should not be a problematic change. The new name is now documented however. Fixes #1375, #1718, #1706
2015-11-12install: never log from install functionsLennart Poettering
Instead, let the caller do that. Fix this by moving masked unit messages into the caller, by returning a clear error code (ESHUTDOWN) by which this may be detected.

2015-11-11execute: Add new PassEnvironment= directiveFilipe Brandenburger
This directive allows passing environment variables from the system manager to spawned services. Variables in the system manager can be set inside a container by passing `--set-env=...` options to systemd-spawn. Tested with an on-disk test.service unit. Tested using multiple variable names on a single line, with an empty setting to clear the current list of variables, with non-existing variables. Tested using `systemd-run -p PassEnvironment=VARNAME` to confirm it works with transient units. Confirmed that `systemctl show` will display the PassEnvironment settings. Checked that man pages are generated correctly. No regressions in `make check`.
2015-11-10defs: rework CONF_DIRS_NULSTR() macroLennart Poettering
The macro is generically useful for putting together search paths, hence let's make it truly generic, by dropping the implicit ".d" appending it does, and leave that to the caller. Also rename it from CONF_DIRS_NULSTR() to CONF_PATHS_NULSTR(), since it's not strictly about dirs that way, but any kind of file system path. Also, mark CONF_DIR_SPLIT_USR() as internal macro by renaming it to _CONF_PATHS_SPLIT_USR() so that the leading underscore indicates that it's internal.
