2014-01-13networkd: DHCPv4 - allow opting out of using DNS serversTom Gundersen
Setting UseDNS=no will ignore any received DNS servers.
2014-01-12networkd: fix wordingTom Gundersen
2014-01-12networkd: generate resolv.confTom Gundersen
This adds support to generate a basic resolv.conf in /run/systemd/network. This file will not take any effect unless a symlink is created from /etc/resolv.conf. Nameservers received over DHCP takes precedence over statically configured ones. Note: /etc/resolv.conf is severely limited, so in the future we will likely rather provide a much more powerfull nss plugin (or something to that effect), but this should allow current users to function without any loss of functionality.
2014-01-12networkd: bridge - remove redundant stateTom Gundersen
We will not insist on getting the reply from rtnl that the bridge was created before considering the bridge ready, as we will be notified about that via udev. We will listen for the rtnl response however, in case the creation of the bridge failed.
2014-01-12networkd: don't automatically reload config at runtimeTom Gundersen
We don't know if the config will be consistent, so do as systemd itself and only load config when the daemon starts (and possibly, in the future, when explicitly requested).
2014-01-12networkd: improve logging a bitTom Gundersen
2014-01-11network: use GNU-ism to simplify macrosZbigniew Jędrzejewski-Szmek
Thanks David!
2014-01-08networkd: print the received DHCPv4 address and gatewayZbigniew Jędrzejewski-Szmek
It seems that networkd stores in_addr.s_addr contents in reverse order (little-endian, not network order). This is a bit confusing, but sd_rtnl evidently likes this order.
2014-01-08networkd: use structured logging for links and bridgesZbigniew Jędrzejewski-Szmek
2014-01-08No need to canonicalize fixed pathsZbigniew Jędrzejewski-Szmek
2014-01-05networkd: refuse to use .network files with missing Address/Gateway keyTom Gundersen
These keys are mandatory in [Address]/[Route] sections. Otherwise, we hit an assert: ens3: setting addresses Assertion 'address->family == 2 || address->family == 10' failed at /build/amd64-generic/tmp/portage/sys-apps/systemd-9999-r1/work/systemd-9999/src/network/networkd-address.c:137, function address_configure(). Aborting. Reported-by: Alex Polvi <alex.polvi@coreos.com> At the same time make sure Route's Destination and Gateway uses the same address family.
2014-01-03networkd: link hash uses 64, not 32 bit keysTom Gundersen
2014-01-03networkd: print the ifindex of added linksTom Gundersen
This debug information may be useful when comapring to dropped rtnetlink messages.
2014-01-03networkd: improve loggingTom Gundersen
This gives a bit better messages when a link is added twice.
2014-01-03networkd: improve link state change loggingTom Gundersen
2014-01-03networkd: add some debug info about notifications we ignoreTom Gundersen
2014-01-03networkd: link - explicitly set the link to be up if the call to IFF_UP succeedsTom Gundersen
No need to wait for the NEWLINK message to arrive.
2014-01-02networkd: fix memory leak in error pathZbigniew Jędrzejewski-Szmek
2014-01-02networkd: do not deference null pointer in cleanupZbigniew Jędrzejewski-Szmek
2014-01-03networkd: dhcp - avoid null pointer dereferenceTom Gundersen
2014-01-03networkd: add more asserts and ignore all events when link has failedTom Gundersen
2014-01-02networkd: only track state of links we are managingTom Gundersen
If a network is not (yet) set for a link, we do not care about its state (as we anyway don't know what to do with it).
2014-01-02networkd: improve loggingTom Gundersen
Remove redundant messages, add some debugging ones and make wording more uniform.
2014-01-02networkd: fix NULL pointer derefKay Sievers
2014-01-02networkd: fix getting initial stateTom Gundersen
We were requesting the state and then ignoring it...
2014-01-01networkd: add DHCPv4 supportTom Gundersen
This adds basic DHCPv4 support. Link-sense is enabled unconditionally, but the plan is to make that configurable. I tested this in a VM with lots of NICs and over wifi in the various coffee shops I found this Christmas, but more testing would definitely be appreciated.
2014-01-01networkd: distinguish between static and dynamic addresses/routesTom Gundersen
Static addresses/routes are associated with a network. Dynamic addresses/routes are associtade with links (as the corresponding network may be shared by several links).
2014-01-01network: add support for dropping addressTom Gundersen
2013-12-18core,logind,networkd: check for udev device initialization via enumeration ↵Lennart Poettering
matches Instead of checking each device after we got it, check wuth an enumeration filter instead, to make it more efficient.
2013-12-18core,logind,networkd: don't pick up devices from udev before they finished ↵Lennart Poettering
udev initialization Managers shouldn't pick up the devices the manage before udev finished initialization, hence check explicitly for that.
2013-12-17networkd: bridge - fix state machineTom Gundersen
We were entering BRIDGE_STATE_CREATED rather than BRIDGE_STATE_READY.
2013-12-17networkd: link - remove useless statesTom Gundersen
Rework the state-machine a bit.
2013-12-17networkd: rename link_update_flags to link_updateTom Gundersen
We are likely to track more than the flags in the future.
2013-12-17networkd: add support for Route sectionsTom Gundersen
2013-12-17networkd: correct logging messageTom Gundersen
2013-12-16network: more asserts to shut up scan-buildThomas Hindoe Paaboel Andersen
2013-12-16network: use SETLINK to bring up interfacesTom Gundersen
2013-12-16rtnl: replace message_append by typesafe versionsTom Gundersen
2013-12-16rtnl: simplify route_new()Tom Gundersen
Drop most of the arguments and instead introduce set_dst_prefixlen().
2013-12-16rtnl: simplify link_new()Tom Gundersen
Drop most of the arguments and instead introduce link_set_{flags,type}.
2013-12-13event: be more conservative when returning errors from event handler callbacksLennart Poettering
We really should return errors from event handlers if we have a continous problem and don't know any other solution.
2013-12-11event: hook up sd-event with the service watchdog logicLennart Poettering
Adds a new call sd_event_set_watchdog() that can be used to hook up the event loop with the watchdog supervision logic of systemd. If enabled and $WATCHDOG_USEC is set the event loop will ping the invoking systemd daemon right after coming back from epoll_wait() but not more often than $WATCHDOG_USEC/4. The epoll_wait() will sleep no longer than $WATCHDOG_USEC/4*3, to make sure the service manager is called in time. This means that setting WatchdogSec= in a .service file and calling sd_event_set_watchdog() in your daemon is enough to hook it up with the watchdog logic.
2013-12-04networkd: add link-sense and simplify state-machine a bitTom Gundersen
This listens to rtnetlink for changes to IFF_UP and IFF_LOWER_UP (link sense). The latter is simply logged at the moment, but will be useful once we add dhcp support.
2013-11-28Remove some unused variablesZbigniew Jędrzejewski-Szmek
2013-11-28networkd: fix several Address entries in [Network] sectionTom Gundersen
2013-11-27networkd: Initialize variable to NULLPatrik Flykt
If any number of arguments are given, _cleanup_manager_free_ is used with unitialized memory causing a crash.
2013-11-26networkd: add bridge supportTom Gundersen
A bridge is specified in a .netdev file with a section [Bridge] and at least the entry Name=. A link may be joined to a bridge if the .network applied to it has a Bridge= entry giving the name of the bridge in its [Network] section. We eagerly create all bridges on startup, and links are added to bridges as soon as they both appear.
2013-11-26networkd: minor fixesTom Gundersen
In particular, store the ifname, though we should only use it carefully, as it is not guaranteed to be stable. Using it for logging is fine though.
2013-11-25networkd: use correct printf formatterDave Reisner
uint64_t can be formatted correctly with %ju, rather than casting to unsigned and potentially losing accuracy.
2013-11-25delete unused variablesThomas Hindoe Paaboel Andersen
