2014-08-27man: add sample glib/sd-event integrationTom Gundersen
This should be moved to man pages, but for now the C code is included directly. Suggested by Zbyszek.

2014-08-26man: reword sd-hibernate-resume description and add linkZbigniew Jędrzejewski-Szmek
"each device" was suggesting that this service might be instantiated multiple times. "hibernation resume" was too jargon-y.
2014-08-26hibernate-resume-generator: add a generator for instantiating the resume unit.Ivan Shapovalov
hibernate-resume-generator understands resume= kernel command line parameter and instantiates the systemd-resume@.service accordingly if it is passed. This enables resume from hibernation using device specified on the kernel command line, and it may be specified either as "/dev/disk/by-foo/bar" or "FOO=bar", not only "/dev/sdXY" which is understood by the in-kernel implementation. So now resume= is brought on par with root= in terms of possible ways to specify a device.
2014-08-26hibernate-resume: add a tool to write a device node's major:minor to ↵Ivan Shapovalov
/sys/power/resume. This can be used to initiate a resume from hibernation by path to a swap device containing the hibernation image. The respective templated unit is also added. It is instantiated using path to the desired resume device.

2014-08-22core: introduce "poweroff" as new failure action typesLennart Poettering
Also, change the default action on a system start-up timeout to powering off.
2014-08-22core: add support for a configurable system-wide start-up timeoutLennart Poettering
When this system-wide start-up timeout is hit we execute one of the failure actions already implemented for services that fail. This should not only be useful on embedded devices, but also on laptops which have the power-button reachable when the lid is closed. This devices, when in a backpack might get powered on by accident due to the easily reachable power button. We want to make sure that the system turns itself off if it starts up due this after a while. When the system manages to fully start-up logind will suspend the machine by default if the lid is closed. However, in some cases we don't even get as far as logind, and the boot hangs much earlier, for example because we ask for a LUKS password that nobody ever enters. Yeah, this is a real-life problem on my Yoga 13, which has one of those easily accessible power buttons, even if the device is closed.
2014-08-21service: allow services of Type=oneshot that specify no ExecStart= commandsLennart Poettering
This is useful for services that simply want to run something on shutdown, but not at bootup. They should only set ExecStop= but leave ExecStart= unset.
2014-08-21core: allow informing systemd about service status changes with RELOADING=1 ↵Lennart Poettering
and STOPPING=1 sd_notify() messages
2014-08-21journalctl: add "-t --identifier=STRING" optionHarald Hoyer
This turns journalctl to the counterpart of systemd-cat. Messages sent with systemd-cat --identifier foo --prioritiy debug can now be shown with journalctl --identifier foo --prioritiy debug "--identifier" is not merged with "--unit" to make a clear distinction between syslog and systemd units. syslog identifiers can be chosen freely by anyone.

2014-08-19socket: suffix newly added TCP sockopt time properties with "Sec"Lennart Poettering
This is what we have done so far for all other time values, and hence we should do this here. This indicates the default unit of time values specified here, if they don't contain a unit.
2014-08-19Revert "socket: introduce SELinuxLabelViaNet option"Lennart Poettering
This reverts commit cf8bd44339b00330fdbc91041d6731ba8aba9fec. Needs more discussion on the mailing list.
2014-08-19tmpfiles: add new 'r' line type to add UIDs/GIDs to the pool to allocate ↵Lennart Poettering
UIDs/GIDs from This way we can guarantee a limited amount of compatibility with login.defs, by generate an appopriate "r" line out of it, on package installation.
2014-08-19socket: introduce SELinuxLabelViaNet optionMichal Sekletar
This makes possible to spawn service instances triggered by socket with MLS/MCS SELinux labels which are created based on information provided by connected peer. Implementation of label_get_child_label derived from xinetd. Reviewed-by: Paul Moore <pmoore@redhat.com>

2014-08-18networkd: warn when ignoring unsupported tuntap optionsTom Gundersen
The interface for creating tuntap devices should be ported to rtnl so it would support the same settings as other kinds. In the meantime, the best one can do is to drop in a .link file to set the desired options.
2014-08-18memfd: internalize functions, drop sd_memfd typeDaniel Mack
Remove the sd_ prefix from internal functions and get rid of the sd_memfd type. As a memfd is now just a native file descriptor, we can get rid of our own wrapper type, and also use close() and dup() on them directly.
2014-08-15networkd: add support for Domains= to .network filesTom Gundersen
This allows the search/routing domanis to be specified per link/network and be passed on to resolved.
2014-08-15networkd: rename UseDomainName to UseDomainsTom Gundersen
This option will also apply to the search domains, so make it plural.
2014-08-15man: drop references to removed and obsolete 'systemctl load' commandLennart Poettering
2014-08-14socket: Add support for TCP defer acceptSusant Sahani
TCP_DEFER_ACCEPT Allow a listener to be awakened only when data arrives on the socket. If TCP_DEFER_ACCEPT set on a server-side listening socket, the TCP/IP stack will not to wait for the final ACK packet and not to initiate the process until the first packet of real data has arrived. After sending the SYN/ACK, the server will then wait for a data packet from a client. Now, only three packets will be sent over the network, and the connection establishment delay will be significantly reduced.
2014-08-14socket: Add Support for TCP keep alive variablesSusant Sahani
The tcp keep alive variables now can be configured via conf parameter. Follwing variables are now supported by this patch. tcp_keepalive_intvl: The number of seconds between TCP keep-alive probes tcp_keepalive_probes: The maximum number of TCP keep-alive probes to send before giving up and killing the connection if no response is obtained from the other end. tcp_keepalive_time: The number of seconds a connection needs to be idle before TCP begins sending out keep-alive probes.
2014-08-15networkd: don't respect domainname from DHCP by defaultTom Gundersen
Most routers will send garbage, so make this opt-in only.
2014-08-14Revert "socket: add support for TCP fast Open"Lennart Poettering
This reverts commit 9528592ff8d7ff361da430285deba8196e8984d5. Apparently TFO is actually the default at least for the server side now. Also the setsockopt doesn't actually take a bool, but a qlen integer.
2014-08-14socket: add support for TCP fast OpenSusant Sahani
TCP Fast Open (TFO) speeds up the opening of successiveTCP) connections between two endpoints.It works by using a TFO cookie in the initial SYN packet to authenticate a previously connected client. It starts sending data to the client before the receipt of the final ACK packet of the three way handshake is received, skipping a round trip and lowering the latency in the start of transmission of data.
2014-08-14socket: add support for tcp nagleSusant Sahani
This patch adds support for TCP TCP_NODELAY socket option. This can be configured via NoDelay conf parameter. TCP Nagle's algorithm works by combining a number of small outgoing messages, and sending them all at once. This controls the TCP_NODELAY socket option.
2014-08-14timer: order OnCalendar units after timer-sync.target if DefaultDependencies=noTobias Geerinckx-Rice
Avoids triggering timers prematurely on systems with significantly inaccurate clocks, or some embedded platforms that lack one entirely.
2014-08-12networkd: disable ipv4ll default routes by defaultTom Gundersen
This causes machines without connectivity to hang where they would otherwise fail. Keep it opt-in for now, but consider whether we sholud just drop it.

2014-08-08udev: link_setup - respect kernel name assign policyTom Gundersen
Newer kernels export meta-information about the origin of an ifname. Respect this from the ifname rename logic. We do not rename any interfaces that was originally named by userspace, nor once which have already been renamed from userspace. Moreover, we optionally do not (the default) rename interfaces which the kernel claims to have named in a predictable way.

2014-08-03bootchart: don't parse /proc/uptime, use CLOCK_BOOTTIMEKarel Zak
* systemd-bootchart always parses /proc/uptime, although the information is unnecessary when --rel specified * use /proc/uptime is overkill, since Linux 2.6.39 we have clock_gettime(CLOCK_BOOTTIME, ...). The backend on kernel side is get_monotonic_boottime() in both cases. * main() uses "if (graph_start <= 0.0)" to detect that /proc is available. This is fragile solution as graph_start is always smaller than zero on all systems after suspend/resume (e.g. laptops), because in this case the system uptime includes suspend time and uptime is always greater number than monotonic time. For example right now difference between uptime and monotonic time is 37 hours on my laptop. Note that main() calls log_uptime() (to parse /proc/uptime) for each sample when it believes that /proc is not available. So on my laptop systemd-boochars spends all live with /proc/uptime parsing + nanosleep(), try strace /usr/lib/systemd/systemd-bootchart to see the never ending loop. This patch uses access("/proc/vmstat", F_OK) to detect procfs.
2014-07-31man: add udev.conf(5)Zbigniew Jędrzejewski-Szmek
We generally have separate man pages for all configuration files. In this case udev.conf was already described in systemd-udevd.service(8), but it was hard to find. Docbook makes it hard to add a .so link from a different section, so describe udev.conf in its own page.
