Sara Dickinson 729af1d159 Allow backed-off upstreams to be re-instated if all our upstreams are unusable (e.g. if the network is down). 
But limit re-tries for a given netreq to the total number of upstreams before failing. This should (roughly) allow 2 retries per upstream of the correct transport before bailing out. Otherwise we are stuck in a loop retrying forever!

Sara Dickinson 42945cfc08 Make the backoff time incrementally increase until the upstream starts working again 2017-09-08 17:28:37 +01:00
Sara Dickinson 2e4e3873e4 First pass at fixing problems when connections to servers are lost. 
Need to reset connection state if connections fail at setup and on read/write if there are no more messages queued.
This means we will back-off servers that fail, so we should think about using a shorter backoff default in stubby
because otherwise temporarily loss of the network connection will mean having to restart stubby.
Also some minor changes to logging.

Daniel Kahn Gillmor 9de4d6537b Implement sensible default padding policy. 
This commit changes the semantics of tls_query_padding_blocksize()
slightly.  Where previously both 0 and 1 meant "no padding", this
commit changes 1 to mean "pad using a sensible policy".

At NDSS 2017's DNS privacy workshop, I presented an empirical study of
DNS padding policies:

https://www.internetsociety.org/events/ndss-symposium/ndss-symposium-2017/dns-privacy-workshop-2017-programme#session3

The slide deck is here:
https://dns.cmrg.net/ndss2017-dprive-empirical-DNS-traffic-size.pdf

The resulting recommendation from the research is that a simple
padding policy is relatively cheap and still protective of metadata
when DNS traffic is encrypted:

 * queries should be padded to a multiple of 128 octets
 * responses should be padded to a multiple of 468 octets

Since getdns is only currently doing queries over tls, we only have to
implement the first part of this policy :)

Sara Dickinson f0f3c43552 - Add a new mode where for TLS (and infact TCP too) the upstream selection simply cycles over all the upstreams rather than treating them as an ordered list and always using the first open one. 
- Make IP field in debug output fixed width
- Collect all the one line config options at the top of the stubby.conf file to make it easier to read
