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 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.

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)
