Sara Dickinson 67e282edd1 More work on transport/upstream fallback. TLS and UDP fallback not working yet.... Probably need to maintain a current upstream for each transport to get this working properly 2015-06-22 18:02:28 +01:00

wtoorop d819bc901b Merge pull request #104 from saradickinson/features/transport_api 
Commit addition of transport list to the API.

Sara Dickinson 8dd8d90e74 Commit addition of transport list to the API. 
- set and get functions are added.
- Existing transport functions retained for backwards compatibility.
- Basic combinations work as before, but underlying functional changes and cleanup are not complete yet...
- Context level options for timeouts and max_transactions_per_tcp_connection coming soon...

Sara Dickinson 3de15ad782 Change internal transport handling to use a list, not a fixed type 2015-04-24 16:29:08 +01:00
Sara Dickinson f2ae55858f First pass at making handshake async. Lots of issues with this code still 
- timeouts are not being rescheduled on fallback
- several error cases are not being handled correctly (e.g. 8.8.8.8) and a user callback is not always called
- the fallback mechanism is not generic (specific to tls to tcp)
 2015-04-23 17:46:31 +01:00
Sara Dickinson 6c7ffc4e4e 1) Fix enum mapping error. 
2) Also add detection of TLS 1.2 in openssl during configure and warn that it if not available then TLS will not be available. Using TLS_ONLY in stub mode will then error with BAD_CONTEXT. TLS/TCP will fallback to TCP.

3) Explicitly disallow use of TLS_ONLY in RECURSIVE mode since it isn't supported yet. TLS/TCP will fallback to TCP.

4) Fix for MAC OS X build where openssl not linked correctly
 2015-04-17 18:38:13 +01:00
Sara Dickinson ab4fb8d9e9 Enable GETDNS_TRANSPORT_TLS_ONLY_KEEP_CONNECTIONS_OPEN for libunbound. Should only be used in stub mode. 
GETDNS_TRANSPORT_TLS_FIRST_AND_FALL_BACK_TO_TCP_KEEP_CONNECTIONS_OPEN still just does TCP.
Also some tidy up of new transport types.

Willem Toorop a0cb4e1774 Move stub resolving to stub.c again 
Merged hostname.c and service.c in general so that getdns_general_ns can become static.
Removed specialized synchronous handling from return_validation_chain code.
Removed un_timed_resolve (specialized sync handling is not needed anymore)
Renamed inter-object file symbols to priv_<name> and made intra-object symbols static as much as possible.
