Adam Harrison 264e5c9979 Merge pull request #2541 from weaveworks/issues/2540-withnetns 
Change namespace via nsenter, for plugin arp-config step

Martynas Pumputis 4a49ff3083 Replace usage of WithNetNSUnsafe in plugin/net/watcher.go with safer version 
Unsafe version was in ConfigureARPforVeths; replacement is via `weaveutil configure-arp`

Matthias Radestock 85ac8177ad inline (u)int8 array to string conversion 
so that the code compiles regardless of the uts.Release array type,
which varies across platforms.

Fixes #2506

Bryan Boreham 50a8dc1383 Add weaveutil process-addrs 
Fetches addresses for every veth that is in a network namespace and
attached to the specified bridge.  Works by iterating over every process.

Bryan Boreham 71491138aa Extract function to return all current process ids 
This implementation should be more efficient because it only uses the
names under /proc, whereas the previous implementation fetched the
full directory entry for each one, and sorted them too.

Adam Harrison 69b688b357 Merge pull request #2509 from weaveworks/issues/2503-persist-peers-fix 
Create restart.sentinel after storing the peer list
 2016-09-21 10:09:05 +01:00
Martynas Pumputis cdeae04238 Create restart.sentinel after storing peer list 
Otherwise, we risk to lose peer list when any failure happens after
the creation but before storing the list and as a consequence,
the weave container gets restarted.

Bryan Boreham ac4246e1f5 Pass in default subnet when creating 'weave' plugin network. 
New behaviour in Docker 1.12 means it disregards a plugin-supplied
address pool that overlaps an existing route, which causes a hang as
noted in #2469. When we pass in the subnet, Docker believes we really
do want that address range and avoids the hang.

Martynas Pumputis fd0a7efa23 Fix "weave ps" output when weave is not running 
The #2418 has changed a behaviour of "weave ps" which outputs
"Link not found" in the case of weave not running. The previous
behaviour was to output an empty line.

- Do not re-enter the root netns when querying weave bridge.

Martynas Pumputis 7f5c37ef1e Fix "weave ps" 
Make sure that any network namespace changes happens at the end of
the cmd invocation. Otherwise, we are risking to end up in a situation
in which OS scheduling threads are in a "wrong" namespace.

See WithNetNS for more details.

Martynas Pumputis 05baa566c6 Refactor common.GetBridgeNetDev 
- Optimize. Use LinkByName instead of iterating over list of available
  links. Linux does not support interfaces with the same names.
- Remove unnecessary indirection in utility functions which return
  common.NetDev.

Bryan Boreham 37fd54f20b Perform AWSVPC checks for attach in script rather than in weaveutil 2016-06-08 16:44:54 +01:00
Martynas Pumputis 7670fed72c Add AWSVPC setup routines to the attach script 
When running in the AWSVPC mode, we need to do the following:

- Keep the HW TX offloading on.
- Check that the allocated address belongs to the default subnet,
  because only one subnet is allowed and it should be the default one.

If it is not possible to determine whether AWSVPC is on, we ignore
all the steps, because the attachment routines have to work
regardless whether the router is running and the AWSVPC detection
is done by querying the /ipinfo/tracker endpoint served by
the router.
 2016-06-08 16:44:54 +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.

Bryan Boreham a1c3cba363 Invert multicast option in plugin 
Now it's off by default, and there is an option to enable the

We turn it on for the `weave` network created when we start the plugin.
