networkd: (de)serialize more state and support expiring routes
 2015-11-03 15:03:50 +01:00
Tom Gundersen c598ac7626 networkd: link - port to extract_first_word() 2015-10-30 12:32:49 +01:00
Tom Gundersen f833694d4f networkd: route - add expiration support 
This should really live in the kernel, but the netlink API currently
does not support it. Until support has been added, expire the route
from userspace.

Tom Gundersen 0bc70f1d9c networkd: link - (de)serialize IPv4LL and DHCPv4 addresses 
This initializes the clients to try rebinding the preexisting
addresses before doing anything else.

Tom Gundersen c4a03a5669 networkd: link - deserialize 
For now only deserialize some basic state and the applied addresses.

When a link is added, try to deserialize it's state from /run. This
is relevant only when networkd is restarted at runtime.

Hristo Venev 4701725cd5 network: fix use-after-free in link_free 
Freeing a link removes it both from addresses and addresses_foreign,
causing SIGSEGV if one of the sets is freed.

Tom Gundersen ceabaf0fea networkd: ndisc - make logging messages uniform 
Refer to Router Discovery rather than ICMPv6.

Tom Gundersen 84de38c569 networkd: manager/link - only serialize once per event-loop iteration 
Every time the state is written out we may trigger third-party apps, so
let's be a bit more careful about writing this out unnecessarily.

Tom Gundersen e7780c8d44 networkd: link - serialize addresses 2015-10-21 03:24:23 +02:00
Tom Gundersen adda1ed94a networkd: address - distinguish between addresses added by us and by others 
We only keep the addresses that we added ourselves in link->addresses, and
introduce a new set link->addresses_foreign to keep addresses of unknown
origin.

Only functional change is that "foreign" addresses no longer prevent a link
from entering "configured" state.

Tom Gundersen 6666907869 networkd: address - merge _change() into _configure() 
These functions are almost entirely the same, so avoid duplication.
 2015-10-21 02:35:31 +02:00
Tom Gundersen 8012cd3919 networkd: link - only consider configured when all addresses are ready 
We were considering a link configured whilst its IPv6 addresses were still
tentative.

Fixes issue #650.

Tom Gundersen ce6c77ebf1 networkd: address - introduce address_is_ready()

Tom Gundersen 91b5f99731 networkd: make address_{establish,release}() static 
No need to expose these functions, but rather call them from address_{add,drop}.

Tom Gundersen cf1d700da3 networkd: address - store active addresses in a Set rather than a List 
We need to be able to look these things up quickly as we will be updating them
continuously and there can in principle be many of them.

Patrik Flykt 3ada37a21e networkd: Be opportunistic when declaring link configured 
The DHCP variable in the [Network] section of the network configuration
file moves the link to the configured state according to the following:

DHCP=yes   Link is configured when either DHCPv4 or DHCPv6 succeed
DHCP=ipv4  Link is configured only when DHCPv4 succeeds
DHCP=ipv6  Link is configured only when DHCPv6 succeeds
DHCP=no    Neither DHCPv4 or DHCPv6 is attempted

Reported by Martin Pitt.

Georg Müller 6a512301bb Set accept_ra to "2" if enabled in config 
This causes the kernel to accept router advertisments even if
ip forwarding is enabled for this interface.

This fixes #1340.

David Herrmann 9ef61f2e48 sd-lldp: hide internal details 
Currently, sd-lldp.h exports "UPDATE_INFO".. and defines it to a magic
constant '10'. This is completely bogus, so fix it to follow our coding
standards:

  - Prefix exported symbols by SD_LLDP_*

  - Define a separate event-enum for event types

  - Translate internal state to external event-types

Lennart Poettering 75f86906c5 basic: rework virtualization detection API 
Introduce a proper enum, and don't pass around string ids anymore. This
simplifies things quite a bit, and makes virtualization detection more
similar to architecture detection.

Tom Gundersen 9b3a67c55b networkd: dhcp-server - allow configuration of the pool 
The constraints we place on the pool is that it is a contiguous
sequence of addresses in the same subnet as the server address, not
including the subnet nor broadcast addresses, but possibly including
the server address itself. If the server address is included in the
pool it is (obviously) reserved and not handed out to clients.

Tom Gundersen 61986155d2 networkd: dhcp-server - default to manage the whole subnet 
Don't restrict yourselves to 32 leases, simply manage the whole subnet by default.

Tom Gundersen 9963469618 sd-dhcp-server: simplify pool creation 
Merge sd_dhcp_server_set_address() and sd_dhcp_server_set_lease_pool() into
sd_dhcp_server_configure_pool() as the behavior of the two former depends
on the order they are called in. The flexibility is not needed, so let's
just do this in one call.

Lennart Poettering 4f5f911e81 networkd: propagate DNS/NTP server from uplink to dhcp server 
When handing out DHCP leases, try to propagate DNS/NTP server
information from "uplink". The "uplink" is automatically determined as
the network interface with the highest priority default route on it.
