2014-02-07logind: add function session_jobs_reply() to unify the create replyDjalal Harouni
The session_send_create_reply() function which notifies clients about session creation is used for both session and user units. Unify the shared code in a new function session_jobs_reply(). The session_save() will be called unconditionally on sessions since it does not make sense to only call it if '!session->started', this will also allow to update the session state as soon as possible.
2014-02-07core: one step back again, for nspawn we actually can't wait for cgroups ↵Lennart Poettering
running empty since systemd will get exactly zero notifications about it
2014-02-07machined: since we can now somewhat reliable get notifications for dyingLennart Poettering
scopes we don't need to lower the stop timeout anymore
2014-02-07sd-dhcp-client: split sd_dhcp_lease from sd_dhcp_clientTom Gundersen
This allows us users of the library to keep copies of old leases. This is used by networkd to know what addresses to drop (if any) when the lease expires. In the future this may be used by DNAv4 and sd-dhcp-server.
2014-02-07logind: given that we can now relatively safely shutdown sessions copesLennart Poettering
without working cgroup empty notifications there's no need to set the stop timeout of sessions scopes low
2014-02-07core: allow PIDs to be watched by two units at the same timeLennart Poettering
In some cases it is interesting to map a PID to two units at the same time. For example, when a user logs in via a getty, which is reexeced to /sbin/login that binary will be explicitly referenced as main pid of the getty service, as well as implicitly referenced as part of the session scope.

that's requested
2014-02-07logind: rework session shutdown logicLennart Poettering
Simplify the shutdown logic a bit: - Keep the session FIFO around in the PAM module, even after the session shutdown hook has been finished. This allows logind to track precisely when the PAM handler goes away. - In the ReleaseSession() call start a timer, that will stop terminate the session when elapsed. - Never fiddle with the KillMode of scopes to configure whether user processes should be killed or not. Instead, simply leave the scope units around when we terminate a session whose processes should not be killed. - When killing is enabled, stop the session scope on FIFO EOF or after the ReleaseSession() timeout. When killing is disabled, simply tell PID 1 to abandon the scope. Because the scopes stay around and hence all processes are always member of a scope, the system shutdown logic should be more robust, as the scopes can be shutdown as part of the usual shutdown logic.
2014-02-07core: watch SIGCHLD more closely to track processes of units with no ↵Lennart Poettering
reliable cgroup empty notifier When a process dies that we can associate with a specific unit, start watching all other processes of that unit, so that we can associate those processes with the unit too. Also, for service units start doing this as soon as we get the first SIGCHLD for either control or main process, so that we can follow the processes of the service from one to the other, as long as process that remain are processes of the ones we watched that died and got reassigned to us as parent. Similar, for scope units start doing this as soon as the scope controller abandons the unit, and thus management entirely reverts to systemd. To abandon a unit introduce a new Abandon() scope unit method call.
2014-02-07core: fix warningThomas Hindoe Paaboel Andersen

2014-02-06nspawn: fix HAVE_SELINUX ifdefTom Gundersen
2014-02-06transaction: print more information about conflicting jobsZbigniew Jędrzejewski-Szmek
Also remove some debug statement that should not have been committed.
2014-02-06core: only send SIGHUP when doing first kill, not when doing final sigkillLennart Poettering
2014-02-05Update some message formatsZbigniew Jędrzejewski-Szmek
Use PID_FMT/USEC_FMT/... in more places. Also update logind error messages to print the full path to a file that failed. This should make debugging easier for people who do not know off the top of their head where logind stores it state.

2014-02-05man: introduce new "Desktop" property for sessionsLennart Poettering
This is initialized from XDG_SESSION_DESKTOP and is useful for GNOME to recognize its own sessions. It's supposed to be set to a short string identifying the session, such as "kde" or "gnome".
2014-02-05logind: make session type and class settable via the same waysLennart Poettering
If the session type/class is set via environment variables, use that, and otherwise fallback to something that is set via the PAM module command line.
2014-02-05logind: add new "wayland" session typeLennart Poettering
2014-02-05core: don't wait for non-control/non-main processes when killing processes ↵Lennart Poettering
on the host either Since the current kernel cgroup notification logic is easily confused by existing subgroups, let's do the same thing as in containers before. and just not wait for non-control and non-main processes. This should be corrected as soon as we have sane cgroup notifications from the kernel.

Added sd_rtnl_message_append_u8 and few attribute support in sd_rtnl_message_append_u32 IFLA_GROUP, IFLA_TXQLEN, IFLA_NUM_TX_QUEUES, IFLA_NUM_RX_QUEUES
2014-02-04nspawn: various fixes in selinux hookupLennart Poettering
- As suggested, prefix argument variables with "arg_" how we do this usually. - As suggested, don't involve memory allocations when storing command line arguments. - Break --help text at 80 chars - man: explain that this is about SELinux - don't do unnecessary memory allocations when putting together mount option string
2014-02-04Add SELinux support to systemd-nspawnDan Walsh
This patch adds to new options: -Z PROCESS_LABEL This specifies the process label to run on processes run within the container. -L FILE_LABEL The file label to assign to memory file systems created within the container. For example if you wanted to wrap an container with SELinux sandbox labels, you could execute a command line the following chcon system_u:object_r:svirt_sandbox_file_t:s0:c0,c1 -R /srv/container systemd-nspawn -L system_u:object_r:svirt_sandbox_file_t:s0:c0,c1 -Z system_u:system_r:svirt_lxc_net_t:s0:c0,c1 -D /srv/container /bin/sh

2014-01-31s390/getty-generator: initialize essential system terminals/consolesHendrik Brueckner
Ensure to start getty programs on all essential system consoles on Linux on System z. Add these essential devices to the list of virtualization_consoles to always generate getty configurations. For the sake of completion, the list of essential consoles is: /dev/sclp_line0 - Operating system messages applet (LPAR) /dev/ttysclp0 - Integrated ASCII console applet (z/VM and LPAR) /dev/ttyS0 - Already handled by systemd (3215 console on z/VM) /dev/hvc0 - Already handled by systemd (IUCV HVC terminal on z/VM) Depending on the environment, z/VM or LPAR, only a subset of these terminals are available. See also RH BZ 860158[1] "Cannot login via Operating System Console into RHEL7 instance installed on a LPAR". This bugzilla actually blocks the installation of Linux on System z instances in LPAR mode. [1] https://bugzilla.redhat.com/show_bug.cgi?id=860158

2014-01-31core: introduce new stop protocol for unit scopesLennart Poettering
By specifiy a Controller property when creating the scope a client can specify a bus name that will be notified with a RequestStop bus signal when the scope has been asked to shut down, instead of sending SIGTERM to the scope processes themselves. https://bugzilla.redhat.com/show_bug.cgi?id=1032695

2014-01-31networkd: don't check for ifindex in answer to RTM_NEWLINKTom Gundersen
The kernel will not be changed to support this, so drop the code. Listening for all RTM_NEWLINK messages and filtering on name is reliable, so it is not a problem.
2014-01-31libsystemd-dhcp: Update secs field only when sending DiscoverPatrik Flykt
Compute the 'secs' field as seconds since start of lease acquisition procedure. Start off with a value of zero and increase it only for each resent DHCP discover message. See the discussion before and after http://www.ietf.org/mail-archive/web/dhcwg/current/msg05836.html and Section 3.1 of RFC 2131.

2014-01-31use memzero(foo, length); for all memset(foo, 0, length); callsGreg KH
In trying to track down a stupid linker bug, I noticed a bunch of memset() calls that should be using memzero() to make it more "obvious" that the options are correct (i.e. 0 is not the length, but the data to set). So fix up all current calls to memset(foo, 0, length) to memzero(foo, length).
