Willem Toorop f95a052e55 Rewrite DNS proxy in transport/timeout test suites 
To use the new DNS packet conversion functions.
This looses the dependency on ldns for unit tests too.

Linus Nordberg 466302131e Don't treat "domain" or "search" as a nameserver. 
Continue the while fgets() loop as soon as we're done with "domain" or
"search".

Simplify the logic of the function by removing the if else constructs.

Willem Toorop 4fd8d3dddd Replace mini_event extension by default_eventloop 
* default_eventloop was prototyped in getdns_query and is still in there as my_eventloop
  * It interfaces directly with the scheduling primitives of getdns.
  * It can operate entirely from stack and does not have to do
    any memory allocations or deallocations.

* Adapted configure.ac to allow libunbound to be linked with Windows
  (with the removal of winsock_event.c we have no symbol clashed anymore)

* Added STUB_TCP_WOULDBLOCK return code in stub_resolving helper functions,
  to anticipate dealing with edge triggered event loops (versus level triggered). (i.e. Windows)

Daniel Kahn Gillmor 2a50f4d2ac Set tls_auth_failed when any present authentication mechanism fails 
We used to only have hostnames available.  now we have pubkey_pinsets
available as well.

We want upstream->tls_auth_failed to be 1 when any authentication
mechanism we've been asked for fails (and also when we haven't been
given any authentication mechanism at all).

Daniel Kahn Gillmor a9eb9ccca9 Check that the pinset matches if it is configured 
if the upstream is configured to allow fallback, this will not be a
fatal error, but it will still be checked.

Future work:

 * verify any certs higher in the chain than the end-entity cert
 * deal with raw public keys
 * in the fallback case, report to the user whether the pinset match failed
 2015-12-23 18:00:43 +00:00
Daniel Kahn Gillmor d09675539e Provide access to the pinsets during the TLS verification callback 
We do this by associating a getdns_upstream object with the SSL object
handled by that upstream.

This allows us to collapse the verification callback code to a single
function.

Note that if we've agreed that fallback is ok, we are now willing to
accept *any* cert verification error, not just HOSTNAME_MISMATCH.
This is fine, because the alternative is falling back to cleartext,
which would be worse.

We also always set SSL_VERIFY_PEER, since we might as well try to do
so; we'll drop the verification error ourselves if we know we're OK
with falling back.

wtoorop 7230031c0a Merge pull request #119 from dkg/ietf94-privacy-hackathon 
Thank you dkg!  Great work!

Interestingly you've put the configuration of those two features at "context" level.  Since both options (just like cookies) relate to upstreams, I think they should be configurable per upstream as well  (perhaps using the context settings as the defaults, over-loadable by those upstream options).  With my cookie implementation, I've implemented activation with an extension, but cookies also relate to upstreams, so perhaps they should be enableable per upstream as well (and have a global over-loadable setting in context).

Cheers,
-- Willem

Daniel Kahn Gillmor c322a8a330 add -P flag to getdns_query for EDNS padding policy 2015-11-01 15:49:56 +09:00
Daniel Kahn Gillmor 83bf5ab08b actually implement tls_query_padding_blocksize 
since no DNS OPT value has been allocated, i chose a random value in
the experimental/local range.

Daniel Kahn Gillmor 1457c1a2b5 stash tls_query_padding_blocksize in the dns_req from the context 2015-11-01 15:49:56 +09:00
Daniel Kahn Gillmor b3128652f4 add tls_query_padding_blocksize property for getdns_context 
This is a parameter to the getdns_context that tells the context how
much to pad queries that go out over TLS.

It is not yet functional in this commit, but the idea is to pad each
outbound query over TLS to a multiple of the requested blocksize.

Because we only have a set amount of pre-allocated space for dynamic
options (MAXIMUM_UPSTREAM_OPTION_SPACE), we limit the maximum
padding blocksize.

This is a simplistic padding policy.  Suggestions for improved padding
policies are welcome!

Daniel Kahn Gillmor 8291cdb455 add -c flag for EDNS Client Subnet privacy to getdns_query 2015-11-01 15:49:56 +09:00
Daniel Kahn Gillmor 05585281eb add test for context update callback for edns_client_subnet_private 2015-11-01 15:49:56 +09:00
Daniel Kahn Gillmor df3725e635 added edns_client_subnet_private to getdns_context 
https://tools.ietf.org/html/draft-ietf-dnsop-edns-client-subnet-04

Using the above spec, an intermediate resolver may forward a chunk of
the client's IP address to the authoritative resolver.

Setting edns_client_subnet_private to a getdns_context in stub mode
will indicate to the next-hop recursive resolver that the client
wishes to keep their address information private.

Willem Toorop b062974fb1 ub_setup_recursion also for non roadblock avoidance 2015-11-01 15:48:31 +09:00
Daniel Kahn Gillmor 0b388872ea clarify per-query options vs. per-upstream options 
Sending DNS cookies was overwriting any existing options (DNS OPT) in
the outbound query.

Also, DNS cookies may not be the only option that gets set
per-upstream (instead of per-query).

This changeset establishes a set of per-query options (established at
the time of the query), and a buffer of additional space for adding
options based on the upstream is in use.

The size of this buffer is defined at configure time (defaults to 3000
octets).

Just before a query is sent out, we add the per-upstream options to
the query.

Note: we're also standardizing the query in tls too, even though we're
not sending any upstream options in that case at the moment
(edns_cookies are much weaker than TLS itself)

Daniel Kahn Gillmor 3e90795680 enable talking to servers with ECDSA certs 
There is no clear reason to reject servers that don't have RSA certs.
We should accept ECDSA certs as well.

(also, clean up comments about opportunistic TLS)
