Matthias Radestock 10f37db9da tidy up DNSServer fields 
- make Zone, Iface and Upstream public - this is safe and makes sense
  since all are immutable, and the former two are passed to the
  constructor and are thus known anyway, and the latter is derived
  from external information
- remove IfaceName - we can just use Iface instead
- log Upstream on startup

Matthias Radestock de557a3e03 introduce WEAVEDNS_DOCKER_ARGS 
same purpuse as WEAVE_DOCKER_ARGS, except for weavedns
This allows us to get rid if the -fallback option since
WEAVEDNS_DOCKER_ARGS="--dns=..." has the same effect.

Closes #487.

Matthias Radestock b50688b4de act immediately on weave connecting existing addresses 
we simply reset the vars controlling backoff for that address
Note that we do not interrupt any current connection attempt, since
that is hard.

Closes #499.

David Wragg b00be096f7 Fix returns when iterating over Connections() 
d5eb76f32 replaced (*Peer)ForEachConnection into (*Peer)Connections(),
and consequently converted some nested functions into for loops.  But
the "return" statements in those nested functions were left as-was,
and so exited the outer function rather than moving on to the next
iteration.

Fixes #497

Matthias Radestock d708cb7d4e prevent PMTUVerfied handling from blocking 
...due to blocking on sending the pmtu to the forwarder, because the
forwarder has terminated.

Fixes #464.

Matthias Radestock fc22f9664e refactor: improve encapsulation of Forwarder 2015-03-29 12:14:32 +01:00
Matthias Radestock 07c11d87a8 oops 
I broke this in 1eca5e1097

Matthias Radestock 4eda7e361b put back forwarder channel nil check 
since otherwise forward(...) can block indefinitely due to both the
forwarder channel and finshed channel being nil
 2015-03-29 10:36:01 +01:00
Matthias Radestock b6448fa196 more idiomatic closing of forwarders, by closing a 'finished' channel 
The previous scheme set the reference to main channel to nil and then
drained it. That was racy and hence could lead to deadlock in the
following scenario:

1. multiple senders obtain the main channel from the stored reference
2. main channel reference is set to nil
3. main channel is drained
4. multiple senders send to main channel

So the issue here is that the entire forwarder stopping sequence
occurs between senders obtaining of the reference to the main channel,
and then sending on that channel. If more senders sent than there is
capacity in the channel then this leads to deadlock.

David Wragg 78c70023d8 Don't pass the sender UDPAddr through the crypto layer 
The crypto layer doesn't need it, and the cost of an additional
closure allocation for each incoming UDP packet is modest.

Also, make the FrameConsumer the last parameter to IterateFrames.
It seems a more natural ordering.
 2015-03-27 18:05:00 +00:00
David Wragg 0d30df165f Eliminate UDPPacket 
The Name field is not used anywhere, and once that's gone the remaining
pairing of the packet bytes and sender is not worth it.
 2015-03-27 18:05:00 +00:00
David Wragg 4a1d3aeb96 Remove frameLen parameter to FrameConsumer 
It's the same as len(frame)
 2015-03-27 18:05:00 +00:00
David Wragg bc45a363dd Make Encryptor.AppendFrame more consistent with FrameConsumer 
Also removes references to Peer type in crypto.go, to keep it agnostic
of higher-level concerns.

David Wragg a670272a37 Remove name parameter from (*Peers)ForEach consumer function 
It's part of the Peer anyway.

Matthias Radestock f544fc68de enter frame accumulation even after dropping one 
This logically makes more sense, i.e. we keep draining frames from
fwd.ch until we run out.

Matthias Radestock 1c5fee0a5e refactor: simplify Forwarder.run by extracing a helper function 
Also, don't check for failed receive on fwd.ch; it cannot happen and
we weren't doing it everywhere anyway.
