2016-10-24core: simplify skip_seccomp_unavailable() a bitLennart Poettering
Let's prefer early-exit over deep-indented if blocks. Not behavioural change.
2016-10-24update-done: minor clean-upsLennart Poettering
This is a follow-up for fb8b0869a7bc30e23be175cf978df23192d59118, and makes a couple of minor clean-up changes: - The field name in the timestamp file is changed from "TimestampNSec=" to "TIMESTAMP_NSEC=". This is done simply to reflect the fact that we parse the file with the env var file parser, and hence the contents should better follow the usual capitalization of env vars, i.e. be all uppercase. - Needless negation of the errno parameter log_error_errno() and friends has been removed. - Instead of manually calculating the nsec remainder of the timestamp, use timespec_store(). - We now check whether we were able to write the timestamp file in full with fflush_and_check() the way we usually do it.

2016-10-24networkd-ndisc: Don't add NDisc route for local address (#4467)Patrik Flykt
When systemd-networkd is run on the same IPv6 enabled interface where radvd is announcing prefixes, a route is being set up pointing to the interface address. As this will fail with an invalid argument error, the link is marked as failed and the following message like the following will appear in in the logs: systemd-networkd[21459]: eth1: Could not set NDisc route or address: Invalid argument systemd-networkd[21459]: eth1: Failed Should the interface be required by systemd-networkd-wait-online, network-online.target will wait until its timeout hits thereby significantly delaying system startup. The fix is to check whether the gateway address obtained from NDisc messages is equal to any of the interface addresses on the same link and not set the NDisc route in that case.
2016-10-24core: do not assert when sysconf(_SC_NGROUPS_MAX) fails (#4466)Djalal Harouni
Remove the assert and check the return code of sysconf(_SC_NGROUPS_MAX). _SC_NGROUPS_MAX maps to NGROUPS_MAX which is defined in <limits.h> to 65536 these days. The value is a sysctl read-only /proc/sys/kernel/ngroups_max and the kernel assumes that it is always positive otherwise things may break. Follow this and support only positive values for all other case return either -errno or -EOPNOTSUPP. Now if there are systems that want to re-write NGROUPS_MAX then they should not pass SupplementaryGroups= in units even if it is empty, in this case nothing fails and we just ignore supplementary groups. However if SupplementaryGroups= is passed even if it is empty we have to assume that there will be groups manipulation from our side or the kernel and since the kernel always assumes that NGROUPS_MAX is positive, then follow that and support only positive values.

2016-10-24shared, systemctl: teach is-enabled to show installation targetsJan Synacek
It may be desired by users to know what targets a particular service is installed into. Improve user friendliness by teaching the is-enabled command to show such information when used with --full. This patch makes use of the newly added UnitFileFlags and adds UNIT_FILE_DRY_RUN flag into it. Since the API had already been modified, it's now easy to add the new dry-run feature for other commands as well. As a next step, --dry-run could be added to systemctl, which in turn might pave the way for a long requested dry-run feature when running systemctl start.
2016-10-24install: introduce UnitFileFlagsJan Synacek
Introduce a new enum to get rid of some boolean arguments of unit_file_* functions. It unifies the code, makes it a bit cleaner and extensible.

2016-10-22tree-wide: make parse_proc_cmdline() strip "rd." prefix automaticallyZbigniew Jędrzejewski-Szmek
This stripping is contolled by a new boolean parameter. When the parameter is true, it means that the caller does not care about the distinction between initrd and real root, and wants to act on both rd-dot-prefixed and unprefixed parameters in the initramfs, and only on the unprefixed parameters in real root. If the parameter is false, behaviour is the same as before. Changes by caller: log.c (systemd.log_*): changed to accept rd-dot-prefix params pid1: no change, custom logic cryptsetup-generator: no change, still accepts rd-dot-prefix params debug-generator: no change, does not accept rd-dot-prefix params fsck: changed to accept rd-dot-prefix params fstab-generator: no change, custom logic gpt-auto-generator: no change, custom logic hibernate-resume-generator: no change, does not accept rd-dot-prefix params journald: changed to accept rd-dot-prefix params modules-load: no change, still accepts rd-dot-prefix params quote-check: no change, does not accept rd-dot-prefix params udevd: no change, still accepts rd-dot-prefix params I added support for "rd." params in the three cases where I think it's useful: logging, fsck options, journald forwarding options.
2016-10-22udev: change kernel commandline option parsingZbigniew Jędrzejewski-Szmek
- do not crash if an option without value is specified on the kernel command line, e.g. "udev.log-priority" :P - simplify the code a bit - warn about unknown "udev.*" options — this should make it easier to spot typos and reduce user confusion
2016-10-22journald: convert journald to use parse_proc_cmdlineZbigniew Jędrzejewski-Szmek
This makes journald use the common option parsing functionality. One behavioural change is implemented: "systemd.journald.forward_to_syslog" is now equivalent to "systemd.journald.forward_to_syslog=1". I think it's nicer to use this way.

2016-10-21hwdb: add MOUSE_WHEEL_CLICK_COUNT for non-integer click angles (#4440)Peter Hutterer
MOUSE_WHEEL_CLICK_ANGLE has been an integer, and at least libinput (probably the only user) parses it as strict integer. For backwards compatibility, we cannot change it to a decimal number now. Add a new property to list the number of clicks for a full 360 degree rotation, to be specified in addition to the old click angle property. Clients can prefer the new one where available and calculate the decimal value to whatever precision they want.

2016-10-20sysctl: run sysctl service if /proc/sys/net is writable (#4425)Lennart Poettering
This simply changes this line: ConditionPathIsReadWrite=/proc/sys/ to this: ConditionPathIsReadWrite=/proc/sys/net/ The background for this is that the latter is namespaced through network namespacing usually and hence frequently set as writable in containers, even though the former is kept read-only. If /proc/sys is read-only but /proc/sys/net is writable we should run the sysctl service, as useful settings may be made in this case. Fixes: #4370
2016-10-20units: extend stop timeout for user@.service to 120s (#4426)Lennart Poettering
By default all user and all system services get stop timeouts for 90s. This is problematic as the user manager of course is run as system service. Thus, if the default time-out is hit for any user service, then it will also be hit for user@.service as a whole, thus making the whole concept useless for user services. This patch extends the stop timeout to 120s for user@.service hence, so that that the user service manager has ample time to process user services timing out. (The other option would have been to shorten the default user service timeout, but I think a user service should get the same timeout by default as a system service) Fixes: #4206
