2016-06-30sd-event: expose the event loop iteration counter via ↵Lennart Poettering
sd_event_get_iteration() (#3631) This extends the existing event loop iteration counter to 64bit, and exposes it via a new function sd_event_get_iteration(). This is helpful for cases like issue #3612. After all, since we maintain the counter anyway, we might as well expose it. (This also fixes an unrelated issue in the man page for sd_event_wait() where micro and milliseconds got mixed up)
2016-06-28man: clarify NotifyAccess overriding (#3620)Luca Bruno
Type=notify has a magic overriding case where a NotifyAccess=none is turned into a NotifyAccess=main for sanity purposes. This makes docs more clear about such behavior: https://github.com/systemd/systemd/blob/2787d83c28b7565ea6f80737170514e5e6186917/src/core/service.c#L650:L651
2016-06-26man: document what Authenticated: in the systemd-resolve output actually ↵Lennart Poettering

2016-06-24resolved: add option to disable caching (#3592)Martin Pitt
In some cases, caching DNS results locally is not desirable, a it makes DNS cache poisoning attacks a tad easier and also allows users on the system to determine whether or not a particular domain got visited by another user. Thus provide a new "Cache" resolved.conf option to disable it.
2016-06-24Merge pull request #3549 from poettering/resolved-moreTom Gundersen

2016-06-22nspawn: improve man page (#3577)Lennart Poettering
This change documents the existance of the systemd-nspawn@.service template unit file, which was previously not mentioned at all. Since the unit file uses slightly different default than nspawn invoked from the command line, these defaults are now explicitly documented too. A couple of further additions and changes are made, too. Replaces: #3497

2016-06-22watchdog: Support changing watchdog_usec during runtime (#3492)Minkyung
Add sd_notify() parameter to change watchdog_usec during runtime. Application can change watchdog_usec value by sd_notify like this. Example. sd_notify(0, "WATCHDOG_USEC=20000000"). To reset watchdog_usec as configured value in service file, restart service. Notice. sd_event is not currently supported. If application uses sd_event_set_watchdog, or sd_watchdog_enabled, do not use "WATCHDOG_USEC" option through sd_notify.

2016-06-13core: improve seccomp syscall grouping a bitLennart Poettering
This adds three new seccomp syscall groups: @keyring for kernel keyring access, @cpu-emulation for CPU emulation features, for exampe vm86() for dosemu and suchlike, and @debug for ptrace() and related calls. Also, the @clock group is updated with more syscalls that alter the system clock. capset() is added to @privileged, and pciconfig_iobase() is added to @raw-io. Finally, @obsolete is a cleaned up. A number of syscalls that never existed on Linux and have no number assigned on any architecture are removed, as they only exist in the man pages and other operating sytems, but not in code at all. create_module() is moved from @module to @obsolete, as it is an obsolete system call. mem_getpolicy() is removed from the @obsolete list, as it is not obsolete, but simply a NUMA API.

2016-06-10core/execute: add the magic character '!' to allow privileged execution (#3493)Alessandro Puccetti
This patch implements the new magic character '!'. By putting '!' in front of a command, systemd executes it with full privileges ignoring paramters such as User, Group, SupplementaryGroups, CapabilityBoundingSet, AmbientCapabilities, SecureBits, SystemCallFilter, SELinuxContext, AppArmorProfile, SmackProcessLabel, and RestrictAddressFamilies. Fixes partially https://github.com/systemd/systemd/issues/3414 Related to https://github.com/coreos/rkt/issues/2482 Testing: 1. Create a user 'bob' 2. Create the unit file /etc/systemd/system/exec-perm.service (You can use the example below) 3. sudo systemctl start ext-perm.service 4. Verify that the commands starting with '!' were not executed as bob, 4.1 Looking to the output of ls -l /tmp/exec-perm 4.2 Each file contains the result of the id command. ````````````````````````````````````````````````````````````````` [Unit] Description=ext-perm [Service] Type=oneshot TimeoutStartSec=0 User=bob ExecStartPre=!/usr/bin/sh -c "/usr/bin/rm /tmp/exec-perm*" ; /usr/bin/sh -c "/usr/bin/id > /tmp/exec-perm-start-pre" ExecStart=/usr/bin/sh -c "/usr/bin/id > /tmp/exec-perm-start" ; !/usr/bin/sh -c "/usr/bin/id > /tmp/exec-perm-star-2" ExecStartPost=/usr/bin/sh -c "/usr/bin/id > /tmp/exec-perm-start-post" ExecReload=/usr/bin/sh -c "/usr/bin/id > /tmp/exec-perm-reload" ExecStop=!/usr/bin/sh -c "/usr/bin/id > /tmp/exec-perm-stop" ExecStopPost=/usr/bin/sh -c "/usr/bin/id > /tmp/exec-perm-stop-post" [Install] WantedBy=multi-user.target] `````````````````````````````````````````````````````````````````
2016-06-10nspawn: introduce --notify-ready=[no|yes] (#3474)Alessandro Puccetti
This the patch implements a notificaiton mechanism from the init process in the container to systemd-nspawn. The switch --notify-ready=yes configures systemd-nspawn to wait the "READY=1" message from the init process in the container to send its own to systemd. --notify-ready=no is equivalent to the previous behavior before this patch, systemd-nspawn notifies systemd with a "READY=1" message when the container is created. This notificaiton mechanism uses socket file with path relative to the contanier "/run/systemd/nspawn/notify". The default values it --notify-ready=no. It is also possible to configure this mechanism from the .nspawn files using NotifyReady. This parameter takes the same options of the command line switch. Before this patch, systemd-nspawn notifies "ready" after the inner child was created, regardless the status of the service running inside it. Now, with --notify-ready=yes, systemd-nspawn notifies when the service is ready. This is really useful when there are dependencies between different contaniers. Fixes https://github.com/systemd/systemd/issues/1369 Based on the work from https://github.com/systemd/systemd/pull/3022 Testing: Boot a OS inside a container with systemd-nspawn. Note: modify the commands accordingly with your filesystem. 1. Create a filesystem where you can boot an OS. 2. sudo systemd-nspawn -D ${HOME}/distros/fedora-23/ sh 2.1. Create the unit file /etc/systemd/system/sleep.service inside the container (You can use the example below) 2.2. systemdctl enable sleep 2.3 exit 3. sudo systemd-run --service-type=notify --unit=notify-test ${HOME}/systemd/systemd-nspawn --notify-ready=yes -D ${HOME}/distros/fedora-23/ -b 4. In a different shell run "systemctl status notify-test" When using --notify-ready=yes the service status is "activating" for 20 seconds before being set to "active (running)". Instead, using --notify-ready=no the service status is marked "active (running)" quickly, without waiting for the 20 seconds. This patch was also test with --private-users=yes, you can test it just adding it at the end of the command at point 3. ------ sleep.service ------ [Unit] Description=sleep After=network.target [Service] Type=oneshot ExecStart=/bin/sleep 20 [Install] WantedBy=multi-user.target ------------ end ------------

2016-06-07networkd: rename IPv6AcceptRouterAdvertisements to IPv6AcceptRALennart Poettering
The long name is just too hard to type. We generally should avoid using acronyms too liberally, if they aren't established enough, but it appears that "RA" is known well enough. Internally we call the option "ipv6_accept_ra" anyway, and the kernel also exposes it under this name. Hence, let's rename the IPv6AcceptRouterAdvertisements= setting and the [IPv6AcceptRouterAdvertisements] section to IPv6AcceptRA= and [IPv6AcceptRA]. The old setting IPv6AcceptRouterAdvertisements= is kept for compatibility with older configuration. (However the section [IPv6AcceptRouterAdvertisements] is not, as it was never available in a published version of systemd.

2016-06-06network: beef up ipv6 RA support considerablyLennart Poettering
This reworks sd-ndisc and networkd substantially to support IPv6 RA much more comprehensively. Since the API is extended quite a bit networkd has been ported over too, and the patch is not as straight-forward as one could wish. The rework includes: - Support for DNSSL, RDNSS and RA routing options in sd-ndisc and networkd. Two new configuration options have been added to networkd to make this configurable. - sd-ndisc now exposes an sd_ndisc_router object that encapsulates a full RA message, and has direct, friendly acessor functions for the singleton RA properties, as well as an iterative interface to iterate through known and unsupported options. The router object may either be retrieved from the wire, or generated from raw data. In many ways the sd-ndisc API now matches the sd-lldp API, except that no implicit database of seen data is kept. (Note that sd-ndisc actually had a half-written, but unused implementaiton of such a store, which is removed now.) - sd-ndisc will now collect the reception timestamps of RA, which is useful to make sd_ndisc_router fully descriptive of what it covers. Fixes: #1079

2016-06-03core: always use "infinity" for no upper limit instead of "max" (#3417)Tejun Heo
Recently added cgroup unified hierarchy support uses "max" in configurations for no upper limit. While consistent with what the kernel uses for no upper limit, it is inconsistent with what systemd uses for other controllers such as memory or pids. There's no point in introducing another term. Update cgroup unified hierarchy support so that "infinity" is the only term that systemd uses for no upper limit.
