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

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 7905eda8b7 Some clean up of connection handling. Still a problem with STARTTLS fallback that needs fixing. 2015-04-30 12:24:13 +01:00

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)

Willem Toorop 0ba6af3523 upstreams_cleanup from upstreams_dereference 2015-04-18 22:17:28 +02:00
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

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 f9195fde4d getdns_context_set_follow_redirects not changed 
Error in previous commit.
Nothing changed with getdns_context_set_follow_redirects.
It is simply not implemented

can also be called after context create now.

Willem Toorop 73dc0f27da fix: local_hosts set keys and shallow free returns 2014-10-23 23:25:55 +02:00
Willem Toorop 4a3d7fd8b2 Replace ldns_rbtree with getdns_rbtree 
As much as possible.
In dnssec ldns_rbtree is inderectly used via the dnssec_zone struct

This change forces use to embed the data in the nodes as getdns_rbtree does not have a data attribute. This is good because lesser allocs and free's and thus slightly faster and less likely to leak memory.
