2015-11-25resolved: add a generic DnsSearchDomain conceptLennart Poettering
With this change, we add a new object to resolved, "DnsSearchDomain=" which wraps a search domain. This is then used to introduce a global search domain list, in addition to the existing per-link search domain list which is reword to make use of this new object too. This is preparation for implement proper unicast DNS search domain support.
2015-11-25man: fix documentation how /etc/resolv.conf is readLennart Poettering
/etc/resolv.conf is only read when the DNS= setting does not appear at all in resolved.conf, regardless if set to the empty list or anything else. Correct that in the man page.
2015-11-25core: support <soft:hard> ranges for RLIMIT optionsKarel Zak
The new parser supports: <value> - specify both limits to the same value <soft:hard> - specify both limits the size or time specific suffixes are supported, for example LimitRTTIME=1sec LimitAS=4G:16G The patch introduces parse_rlimit_range() and rlim type (size, sec, usec, etc.) specific parsers. No code is duplicated now. The patch also sync docs for DefaultLimitXXX= and LimitXXX=. References: https://github.com/systemd/systemd/issues/1769

2015-11-22man: include the target name when linking to man pages in html outputZbigniew Jędrzejewski-Szmek
Links like http://www.freedesktop.org/software/systemd/man/systemd.socket.html are changed to http://www.freedesktop.org/software/systemd/man/systemd.socket.html#Accept=. This implementation is quick & dirty, and misses various corner cases. A fairly important one is that when a few directives share the same anchor (which happens when multiple directives are described in the same paragraph), generated links for everything except the first one link to an invalid anchor. Another shortcoming is that the formatting does not use the proper generateID machinery, so the anchor name could be wrong in some cases. But it seems to work for a large percentage of links, so seems to be an improvement in usability. When the anchor is missing, we land at the top of the page, which is the same as before. If the anchor were to point to different spot, this would be more confusing... Not sure if that ever happens. Anyway, the user should be able to recover from landing on the wrong place in the page. (Mostly) fixes https://github.com/systemd/systemd/issues/1956.

2015-11-17core: add RemainAfterElapse= setting to timer unitsLennart Poettering
Previously, after a timer unit elapsed we'd leave it around for good, which has the nice benefit that starting a timer that shall trigger at a specific point in time multiple times will only result in one trigger instead of possibly many. With this change a new option RemainAfterElapse= is added. It defaults to "true", to mimic the old behaviour. If set to "false" timer units will be unloaded after they elapsed. This is specifically useful for transient timer units.

2015-11-16tmpfiles: create subvolumes for "v", "q", and "Q" only if / is a subvolumeLennart Poettering
It's not a good idea to create subvolumes for parts of the OS tree (such as /home, or /var) if the root directory is not a subvolume too. We shouldn't assume control of "heavier" objects such as subvolumes, if the originating object (the root directory) is a "light-weight" object, i.e. a plain directory. Effectively this means that chroot() environments that are run on a plain directory do not have to deal with problems around systemd creating subvolumes that cannot be removed with a simple "rm" anymore. However, if the chroot manager creates a proper subvolume for such an environment it will also get further subvolumes placed in there, under the assumption that the manager understands the concept of subvolumes in that case.

2015-11-13logind: add a new UserTasksMax= setting to logind.confLennart Poettering
This new setting configures the TasksMax= field for the slice objects we create for each user. This alters logind to create the slice unit as transient unit explicitly instead of relying on implicit generation of slice units by simply starting them. This also enables us to set a friendly description for slice units that way.

nginx defines an uppercase "M" that way (in contrast to the lowercase "m" for "minute"), and it sounds like an OK logic to follow, so that we understand a true superset of time values nginx understands. http://nginx.org/en/docs/syntax.html

stop managing per-interface IP forwarding settings

Remove support for RequiresOverridable= and RequisiteOverridable=
2015-11-13networkd: stop managing per-interface IP forwarding settingsLennart Poettering
As it turns out the kernel does not support per-interface IPv6 packet forwarding controls (unlike as it does for IPv4), but only supports a global option (#1597). Also, the current per-interface management of the setting isn't really useful, as you want it to propagate to at least one more interface than the one you configure it on. This created much grief (#1411, #1808). Hence, let's roll this logic back and simplify this again, so that we can expose the same behaviour on IPv4 and IPv6 and things start to work automatically again for most folks: if a network with this setting set is set up we propagate the setting into the global setting, but this is strictly one-way: we never reset it again, and we do nothing for network interfaces where this setting is not enabled. Fixes: #1808, #1597.
2015-11-12nspawn: add new --network-veth-extra= switch for defining additional veth linksLennart Poettering
The new switch operates like --network-veth, but may be specified multiple times (to define multiple link pairs) and allows flexible definition of the interface names. This is an independent reimplementation of #1678, but defines different semantics, keeping the behaviour completely independent of --network-veth. It also comes will full hook-up for .nspawn files, and the matching documentation.
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").
2015-11-12man: improve the unit file enable state table a bitLennart Poettering
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

For all units ensure there's an "Automatic Dependencies" section in the man page, and explain which dependencies are automatically added in all cases, and which ones are added on top if DefaultDependencies=yes is set. This is also done for systemd.exec(5), systemd.resource-control(5) and systemd.unit(5) as these pages describe common behaviour of various unit types.
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`.
2015-11-11networkd: IPv6 router discovery - follow IPv6AcceptRouterAdvertisemnt=Tom Gundersen
The previous behavior: When DHCPv6 was enabled, router discover was performed first, and then DHCPv6 was enabled only if the relevant flags were passed in the Router Advertisement message. Moreover, router discovery was performed even if AcceptRouterAdvertisements=false, moreover, even if router advertisements were accepted (by the kernel) the flags indicating that DHCPv6 should be performed were ignored. New behavior: If RouterAdvertisements are accepted, and either no routers are found, or an advertisement is received indicating DHCPv6 should be performed, the DHCPv6 client is started. Moreover, the DHCP option now truly enables the DHCPv6 client regardless of router discovery (though it will probably not be very useful to get a lease withotu any routes, this seems the more consistent approach). The recommended default setting should be to set DHCP=ipv4 and to leave IPv6AcceptRouterAdvertisements unset.
