2016-06-14util-lib: rework get_process_cmdline() (#3529)Lennart Poettering
This reworks get_process_cmdline() quite substantially, fixing the following: - Fixes: https://github.com/systemd/systemd/pull/3512/commits/a4e3bf4d7ac2de51191ce136ee9361ba319e106c#r66837630 - The passed max_length is also applied to the "comm" name, if comm_fallback is set. - The right thing happens if max_length == 1 is specified - when the cmdline "foobar" is abbreviated to 6 characters the result is not "foobar" instead of "foo...". - trailing whitespace are removed before the ... suffix is appended. The 7 character abbreviation of "foo barz" is hence "foo..." instead of "foo ...". - leading whitespace are suppressed from the cmdline - a comprehensive test case is added
2016-06-14resolved: in the ResolveHostname() bus call, accept IP addresses with scopeLennart Poettering
When we get a literal IP address as string that includes a zone suffix, process this properly and return the parsed ifindex back to the client, and include it in the canonical name in case of a link-local IP address.

2016-06-14manager: reduce complexity of unit_gc_sweep (#3507)Lukáš Nykrýn
When unit is marked as UNSURE, we are trying to find if it state was changed over and over again. So lets not go through the UNSURE states again. Also when we find a GOOD unit lets propagate the GOOD state to all units that this unit reference. This is a problem on machines with a lot of initscripts with different starting priority, since those units will reference each other and the original algorithm might get to n! complexity. Thanks HATAYAMA Daisuke for the expand_good_state code.

2016-06-14build: fix missing symbol for old kernel headers (#3530)Andrew Jeddeloh
Fix issue where IN6_ADDR_GEN_MODE_STABLE_PRIVACY is undefined but IFLA_INET6_ADDR_GEN_MODE is defined and thus the former does not get fixed in missing.h. This occurs with kernel headers new enough to have the IFLA_INET6_ADDR_GEN_MODE but old enough to not yet have IN6_ADDR_GEN_MODE_STABLE_PRIVACY (e.g. 3.18).
2016-06-13systemctl: rework "systemctl status" a bitLennart Poettering
This reworks "systemctl status" and "systemctl show" a bit. It removes the definition of the `property_info` structure, because we can simply reuse the existing UnitStatusInfo type for that. The "could not be found" message is now printed by show_one() itself (and not its caller), so that it is shown regardless by who the function is called. (This makes it necessary to pass the unit name to the function.) This also adds all properties found to a set, and then checks if any of the properties passed via "--property=" is mising in it, if so, a proper error is generated. Support for checking the PID file of a unit is removed, as this cannot be done reasonably client side (since the systemd instance we are talking to might sit on another host) Replaces: #3411 Fixes: #3425 Also see: #3504

2016-06-13nspawn: lock down system call filter a bitLennart Poettering
Let's block access to the kernel keyring and a number of obsolete system calls. Also, update list of syscalls that may alter the system clock, and do raw IO access. Filter ptrace() if CAP_SYS_PTRACE is not passed to the container and acct() if CAP_SYS_PACCT is not passed. This also changes things so that kexec(), some profiling calls, the swap calls and quotactl() is never available to containers, not even if CAP_SYS_ADMIN is passed. After all we currently permit CAP_SYS_ADMIN to containers by default, but these calls should not be available, even then.
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.

2016-06-12process-util: remove broken support for pid==0Zbigniew Jędrzejewski-Szmek
Our functions that query /proc/pid/ support using pid==0 to mean self. get_process_id also seemed to support that, but it was not implemented correctly: the result should be in *uid, not returned, and also it gave completely bogus result when called from get_process_gid(). But afaict, get_process_{uid,gid} were never called with pid==0, so it's not an actual bug. Remove the broken code to avoid confusion.

2016-06-11test-keymap-util: use kbd-model-map/language-fallback-map from $(srcdir)Zbigniew Jędrzejewski-Szmek
This adds (undocumented) environment variables SYSTEMD_KBD_MODEL_MAP and SYSTEMD_LANGUAGE_FALLBACK_MAP, which, if set, override compiled-in locations of those two files. Instead of skipping tests when the maps are not installed, just use the one from the source dir. We still cannot do the mappings the other way if /usr/lib/kbd/keymaps is not present, so truncate the tests in that case. Also tweak the debug messages a bit to make it easier to see which function is failing.
2016-06-10resolved: move verification that link is unmanaged into the proper bus callsLennart Poettering
Previously, we checked only for the various SetLinkXYZ() calls on the Manager object exposed on the bus if the specified interface is managed/unmanaged by networkd (as we don't permit overriding DNS configuration via bus calls if networkd owns the device), but the equivalent SetXYZ() calls on the Link object did not have such a check. Fix that by moving the appropriate check into the latter, as the former just calls that anyway.

2016-06-10systemctl: prolong timeout of "systemctl daemon-reload"Lennart Poettering
Reloading or reexecuting PID 1 means the unit generators are rerun, which are timed out at 90s. Make sure the method call asking for the reload is timed out at twice that, so that the generators have 90s and the reload operation has 90s too. This reworks the daemon_reload() call in systemctl, and makes it exclusively about reloading/reexecing. Previously it was used for other trivial method calls too, which didn't really help readability. As the code paths are now sufficiently different, split out the old code into a new function trivial_method(). This call also does a similar change as c8ad4efb277c3235d58789170af11bb3c847d655 but for the reload/reexec operation. Fixes: #3353
2016-06-10systemctl: don't suppress error code when handling legacy commandsLennart Poettering
For legacy commands such as /sbin/halt or /sbin/poweroff we support legacy fallbacks that talk via traditional SysV way with PID 1 to issue the desired operation. We do this on any kind of error if the primary method of operation fails. When this is the case we suppress any error message that is normally generated, in order to not confuse the user. When suppressing this log message, don't suppress the original error code, because there's really no reason to.

2016-06-10core/execute: add the magic character '!' to allow privileged execution (#3493)Alessandro Puccetti

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 ------------
