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.

2014-07-30man: fix outdated example in systemd.networkHong Shick Pak
The docs for the DHCP= was updated, but not the example.
2014-07-30networkd: ipv4ll - configure link-local address independently of DHCPv4Tom Gundersen
This changes the behavior when both DHCPv4 and IPv4LL are enabled. Before, we would disable IPv4LL when we got a DHCPv4 lease and enable it if the lease was lost. Now we just always set up both, if both are enabled, but the DHCPv4 addresses and routes will always take precedence due to their metric and scope.
2014-07-29udev: unify event timeout handlingKay Sievers
2014-07-29udevd: add --event-timeout commandline optionHannes Reinecke
Some events take longer than the default 30 seconds. Killing those events will leave the machine halfway configured. Add a commandline option '--event-timeout' to handle these cases.
2014-07-25networkd: ipv4ll - default to setting up ipv4ll routesTom Gundersen
This is necessary for non-ipv4ll hosts to communicate with ipv4ll-only hosts on the same link. Defaults to being enabled, but can be opted out. See: <http://avahi.org/wiki/AvahiAutoipd#Routes>

The following bond options are supported by this patch. MIIMonitorSec: Specifies the frequency in milli-seconds that MII link monitoring will occur. UpDelaySec: Specifies the delay time in milli-seconds to enable a link after a link up status has been detected. DownDelaySec: Specifies the delay time in milli-seconds to disable a link after a link failure has been detected. changes: 1.

LacpduTransmitRate option specifies the rate in which link partner to transmit LACPDU packets in 802.3ad mode. Possible values slow : Request partner to transmit LACPDUs every 30 seconds fast : Request partner to transmit LACPDUs every 1 second The default is slow. chages: 1.

2014-07-18systemd-detect-virt: detect s390 virtualizationThomas Blume
A system that is running on a logical partition (LPAR) provided by PR/SM has access to physical hardware (except CPU). It is true that PR/SM abstracts the hardware, but only for sharing purposes. Details are statet at: http://publib.boulder.ibm.com/infocenter/eserver/v1r2/topic/eicaz/eicazzlpar.htm -->-- In other words, PR/SM transforms physical resources into virtual resources so that many logical partitions can share the same physical resources. --<-- Still, from the OS point of view, the shared virtual resource is real hardware. ConditionVirtualization must be set to false if the OS runs directly on PR/SM (e.g. in an LPAR). [zj: reorder code so that variables are not allocated when #if-def is false. Add commit message.]

2014-07-15journal-remote: allow splitting incoming logs by source hostZbigniew Jędrzejewski-Szmek
Previously existing scheme where the file name would be based on the source was just too ugly and unpredicatable. Now there are only two options: 1. just one file (until rotation), 2. one file per source host, using the hostname as filename part. For the cases where the source is specified by the user, only option one is allowed, and the full of the file must be specified.
2014-07-15sd-dhcp-client: make request broadcasts opt-inTom Gundersen
It appears there is no good way to decide whether or not broadcasts should be enabled, there is hardware that must have broadcast, and there are networks that only allow unicast. So we give up and make this configurable. By default, unicast is used, but if the kernel were to inform us abotu certain interfaces requiring broadcast, we could change this to opt-in by default in those cases.
2014-07-14man: systemd.netdev - make it clear that we do not touch preexisting netdevsTom Gundersen
We will happily use bridges/bonds as master devices, but we will not change their settings if they were created by someone else.
2014-07-14networkd: dhcp add vendor class indentifier option 60Susant Sahani
Vendor Class Identifier be used by DHCP clients to identify their vendor type and configuration. When using this option, vendors can define their own specific identifier values, such as to convey a particular hardware or operating system configuration or other identifying information. Vendor-specified DHCP options—features that let administrators assign separate options to clients with similar configuration requirements. For example, if DHCP-aware clients for example we want to separate different gateway and option for different set of people (dev/test/hr/finance) in a org or devices for example web/database servers or let's say in a embedded device etc and require a different default gateway or DNS server than the rest of clients.
2014-07-14networkd: make metric of routes configurableSusant Sahani
Now route metric can be configuted via conf file: example conf: [Match] Name=em1 [Route] Gateway=192.168.1.12 Metric=10 Test: ip route output default via 192.168.1.12 dev em1 metric 10 [tomegun: squash TODO update and reword man page a bit]

2014-07-11journald: turn ForwardToSyslog= off by defaultLennart Poettering
After all, rsyslog and friends nowadays read their data directly from the journal, hence the forwarding is unnecessary in most cases.

Parameters to hostnamectl command are not optional and should not be marked as such in the man page.
