2015-11-13core: add new DefaultTasksMax= setting for system.confLennart Poettering
This allows initializing the TasksMax= setting of all units by default to some fixed value, instead of leaving it at infinity as before.
2015-11-13core: make sure DefaultLimitCPU= and DefaultLimitRTTIME= understand time ↵Lennart Poettering
units, too We added this for the per-unit setting, hence let's enable this for the global default settings too.

When deserializing we can now have an attached network without the various clients yet having been configured. Hence, don't misused the link->network as a check to determine if a link is ready to be used, but check the state explicitly.

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.
2015-11-13networkd: rearrange checks when to write something into sysctl a bitLennart Poettering
Move check whether ipv6 is available into link_ipv6_privacy_extensions() to keep it as internal and early as possible. Always check if there's a network attached to a link before we apply sysctls. We do this for most of the sysctl functions already, with this change we do it for all.
2015-11-13networkd: fix a couple of format string typesLennart Poettering
We really should use %i for ints, and %u for unsigneds, and be careful what we pick depending on the type we want to print.
2015-11-13util-lib: optionally, when writing a string to a file, verify string on failureLennart Poettering
With this change, the idiom: r = write_string_file(p, buf, 0); if (r < 0) { if (verify_one_line_file(p, buf) > 0) r = 0; } gets reduced to: r = write_string_file(p, buf, WRITE_STRING_FILE_VERIFY_ON_FAILURE); i.e. when writing the string fails and the new flag WRITE_STRING_FILE_VERIFY_ON_FAILURE is specified we'll not return a failure immediately, but check the contents of the file. If it matches what we wanted to write we suppress the error and exit cleanly.
2015-11-13udev/path_id: improve and enhance bus detection for Linux on z SystemsLiu Yuan Yuan
Improve and enhance the path_id udev builtin to correctly handle bus' available on Linux on z Systems (s390). Previously, the CCW bus and, in particular, any FCP devices on it, have been treated separately. This commit integrates the CCW bus into the device chain loop. FCP devices and their associated SCSI disks are now handled through the common SCSI handling functions in path_id. This implies also a change in the naming of the symbolic links created by udev. So any backports of this commit to existing Linux distribution must be done with care. If a backport is required, a udev rule must be created to also create the "old-style" symbolic links. Apart from the CCW bus, this commit adds bus support for the: - ccwgroup bus which manages network devices, and - ap bus which manages cryptographic adapters - iucv bus which manages IUCV devices on z/VM
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.

2015-11-12update TODOLennart Poettering
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: drop "override" flag when building transactionsLennart Poettering
Now that we don't have RequiresOverridable= and RequisiteOverridable= dependencies anymore, we can get rid of tracking the "override" boolean for jobs in the job engine, as it serves no purpose anymore. While we are at it, fix some error messages we print when invoking functions that take the override parameter.
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

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.
