Marc CARRE bc94633180 Re-claim IP on start-up when an existing ID has been found. 
- Rewrote conditions to keep c.ident immutable and hopefully makes
things clearer.
- Added a case to tolerate reclaim after we have used CNI (passed CID
is “_” and existing CID is a real container ID).

Martynas Pumputis 58caf38f07 Fix re-attaching of weave router in awsvpc mode 
In order to re-attach the router and make it work in awsvpc mode,
the following has to be done:

- expose_ip on the router
- adjusting arp settings
- restoring host routes

To detect that we run in awsvpc mode, we inspect cmd parameters
of the weave router instead of GET'ing /ipinfo/tracker. This is so,
because the HTTP server started by the router might not be running
at the time of restoration.

Martynas Pumputis 8569cbd4a3 Force transferring of IPAM ranges in a case of Shutdown 
If no peer for transfer is found, we transfer them to
mesh.UnknownPeerName to notify the ring update tracker.

Makes the awsvpc tracker to remove local entries from
the VPC route table when the last peer calls "weave reset".

Adam Harrison adcb1018df Merge pull request #2345 from weaveworks/issues/2344-persist-more 
Fix ring persistence after free space update
 2016-06-09 16:37:57 +01:00
Martynas Pumputis de2a70861c Add GET /ipinfo/tracker 
The endpoint returns the name of tracker. It is used to determine
whether the router is running a tracker.
 2016-06-08 16:44:54 +01:00
Martynas Pumputis 9fc7be83c8 Create a Tracker when starting the router 
The tracker's HandleUpdate method is called by the ring update routines.

In addition, we add a dummy overlay for AWSVPC to make `weave (status|
report)` to produce reasonable reports which includes AWS hosts
connection state.

Martynas Pumputis c260536429 Add AWSVPC Tracker 
The tracker is responsible for managing the AWSVPC route tables
which is used to implement the underlay routing based on VPC.
 2016-06-08 16:44:54 +01:00
Martynas Pumputis 59b3a3c8c5 Add the Tracker interface 
An instance of the interface must implement the HandleUpdate method
which (in the future) will be called when any change to the IPAM ring
occurs.

Martynas Pumputis f50fbc002e Change ipam Universe from Range to CIDR 
There was no code to initialize it as anything else, and this lets us
bake in an assumption that it will always be a CIDR.

Bryan Boreham cda1084777 Check validity of IP subnets 
Be more consistent about this - check in the same way whether at startup
or during allocation.

Martynas Pumputis 85cea672d3 Change the type of entry.Free to address.Count 
This change is backward compatible, because the underlying types of
address.Offset (the previous type) and address.Count are the same
and the Gob encoder does not require types to exactly correspond.
