2016-05-07systemctl: rewrite code to explicitly take care of n_units==0 caseZbigniew Jędrzejewski-Szmek
Coverity was complaing, but it was a false positive (CID #1354669). Nevertheless, it's better to rewrite the code so that units is never null.

2016-05-05logind: drop pointless UINT64_C() macro useLennart Poettering
2016-05-05logind: enforce a limit on inhibitors we hand outLennart Poettering
For similar reasons as the recent addition of a limit on sessions. Note that we don't enforce a limit on inhibitors per-user currently, but there's an implicit one, since each inhibitor takes up one fd, and fds are limited via RLIMIT_NOFILE, and the limit on the number of processes per user.
2016-05-05logind: expose more configuration settings as bus propertiesLennart Poettering
2016-05-05logind: don't include session lists in PropertyChanged messagesLennart Poettering
If we have a lot of simultaneous sessions we really shouldn't send the full list of active sessions with each PropertyChanged message for user and seat objects, as that can become quite substantial data, we probably shouldn't dump on the bus on each login and logout. Note that the global list of sessions doesn't send out changes like this either, it only supports requesting the session list with ListSessions(). If cients want to get notified about sessions coming and going they should subscribe to SessionNew and SessionRemoved signals, and clients generally do that already. This is kind of an API break, but then again the fact that this was included was never documented.
2016-05-05logind: process session/inhibitor fds at higher priorityLennart Poettering
Let's make sure we process session and inhibitor pipe fds (that signal sessions/inhibtors going away) at a higher priority than new bus calls that might create new sessions or inhibitors. This helps ensuring that the number of open sessions stays minimal.
2016-05-05logind: enforce a limit on current user sessionsLennart Poettering
We really should put limits on all resources we manage, hence add one to the number of concurrent sessions, too. This was previously unbounded, hence set a relatively high limit of 8K by default. Note that most PAM setups will actually invoke pam_systemd prefixed with "-", so that the return code of pam_systemd is ignored, and the login attempt succeeds anyway. On systems like this the session will be created but is not tracked by systemd.
2016-05-05core: fix owner user/group output in socket dumpLennart Poettering
The unit file settings are called SocketUser= and SocketGroup= hence name these fields that way in the "systemd-analyze dump" output too. https://github.com/systemd/systemd/issues/3171#issuecomment-216216995

2016-05-05tree-wide: introduce new SOCKADDR_UN_LEN() macro, and use it everywhereLennart Poettering
The macro determines the right length of a AF_UNIX "struct sockaddr_un" to pass to connect() or bind(). It automatically figures out if the socket refers to an abstract namespace socket, or a socket in the file system, and properly handles the full length of the path field. This macro is not only safer, but also simpler to use, than the usual offsetof() + strlen() logic.

2016-05-05core: use an AF_UNIX/SOCK_DGRAM socket for cgroup agent notificationLennart Poettering
dbus-daemon currently uses a backlog of 30 on its D-bus system bus socket. On overloaded systems this means that only 30 connections may be queued without dbus-daemon processing them before further connection attempts fail. Our cgroups-agent binary so far used D-Bus for its messaging, and hitting this limit hence may result in us losing cgroup empty messages. This patch adds a seperate cgroup agent socket of type AF_UNIX/SOCK_DGRAM. Since sockets of these types need no connection set up, no listen() backlog applies. Our cgroup-agent binary will hence simply block as long as it can't enqueue its datagram message, so that we won't lose cgroup empty messages as likely anymore. This also rearranges the ordering of the processing of SIGCHLD signals, service notification messages (sd_notify()...) and the two types of cgroup notifications (inotify for the unified hierarchy support, and agent for the classic hierarchy support). We now always process events for these in the following order: 1. service notification messages (SD_EVENT_PRIORITY_NORMAL-7) 2. SIGCHLD signals (SD_EVENT_PRIORITY_NORMAL-6) 3. cgroup inotify and cgroup agent (SD_EVENT_PRIORITY_NORMAL-5) This is because when receiving SIGCHLD we invalidate PID information, which we need to process the service notification messages which are bound to PIDs. Hence the order between the first two items. And we want to process SIGCHLD metadata to detect whether a service is gone, before using cgroup notifications, to decide when a service is gone, since the former carries more useful metadata.

Fix incorrect string deduplication in udev
2016-05-03strbuf: set the proper character when creating new nodesLubomir Rintel
Commit 82501b3fc added an early break when a terminal node is found to incorrect place -- before setting c. This caused trie to be built that does not correspond to what it points to in buffer, causing incorrect deduplications: # cat /etc/udev/rules.d/99-bug.rules ENV{FOO}=="0" ENV{xx0}=="BAR" ENV{BAZ}=="00" # udevadm test * RULE /etc/udev/rules.d/99-bug.rules:1, token: 0, count: 2, label: '' M ENV match 'FOO' '0'(plain) * RULE /etc/udev/rules.d/99-bug.rules:2, token: 2, count: 2, label: '' M ENV match 'xx0' 'BAR'(plain) * RULE /etc/udev/rules.d/99-bug.rules:3, token: 4, count: 2, label: '' M ENV match 'BAZ' 'x0'(plain) * END The addition of "xx0" following "0" will cause a trie like this to be created: c=\0 c=0 "0" c=0 "xx0" <-- note the c is incorrect here, causing "00" to be c=O "FOO" deduplicated to it c=R "BAR" This in effect caused the usb_modeswitch rule for Huawei modems to never match and this never be switched to serial mode from mass storage.

Alternatively, this could perhaps be removed since it was broken for a long time and noone seemed to care. But it was helpful for me today.

2016-05-03install: cache the presets before evaluatingAlex Crawford
The previous implementation traversed the various config directories, walking the preset files and parsing each line to determine if a service should be enabled or disabled. It did this for every service which resulted in many more file operations than neccessary. This approach parses each of the preset entries into an array which is then used to check if each service should be enabled or disabled.

2016-05-03networkd: add support to set route tableSusant Sahani
networkd: add support to set route table 1. add support to configure the table id. if id is less than 256 we can fit this in the header of route as netlink property is a char. But in kernel this proepty is a unsigned 32. Hence if greater that 256 add this as RTA_TABLE attribute. 2. we are not setting the address family now. Now set this property.
