snuffy	b546497fe0	Add support for older name resolving version libraries like openBSD ... Fix support of OS's like openBSD that use an older nameser.h, this change reverts the defines to the older style which on other systems is found in nameser_compat.h Tested on openBSD 6.0, Debian 8 ASTERISK-26608 #close Change-Id: Iffb36caab8c5aa9dece0ce2d009041f7b56cc86a	9 years ago
Joshua Colp	bdb6d928c5	res_pjsip: Perform resolution when explicit IPv6 transport is used. ... This change fixes the SIP resolver such that if an IPv6 transport is explicitly used it will resolve NAPTR, SRV, and AAAA records. You can explicitly use one by specifying it on an endpoint.

Richard Mudgett	30cd559345	DNS: Need to use the same serializer for a pjproject SIP transaction. ... All send/receive processing for a SIP transaction needs to be done under the same threadpool serializer to prevent reentrancy problems inside pjproject when using an external DNS resolver to process messages for the transaction. * Add threadpool API call to get the current serializer associated with the worker thread. * Pick a serializer from a pool of default serializers if the caller of res_pjsip.c:ast_sip_push_task() does not provide one. This is a simple way to ensure that all outgoing SIP request messages are processed under a serializer. Otherwise, any place where a pushed task is done that would result in an outgoing out-of-dialog request would need to be modified to supply a serializer. Serializers from the default serializer pool are picked in a round robin sequence for simplicity. A side effect is that the default serializer pool will limit the growth of the thread pool from random tasks. This is not necessarily a bad thing. * Made pjsip_resolver.c use the requesting thread's serializer to execute the async callback. * Made pjsip_distributor.c save the thread's serializer name on the outgoing request tdata struct so the response can be processed under the same serializer.

Richard Mudgett	b23f33e7e5	DNS: Fix some corner cases. ... * Fix query_set destruction before we are done kicking the queries off. * Fixed no queries requested handling. * Add empty queries request unit test. * Added missing allocation check in ast_dns_query_set_add(). * Made initial pjsip resolving query vector slightly larger.

Richard Mudgett	83bc9d366d	pjsip_resolver.c: Fix debug code to only execute at acceptable debug level. ... Change-Id: I1716c93d6e097ad28128ecb9e806aac7a4180c8a	11 years ago
Joshua Colp	a3cec44a0a	res_pjsip: Add external PJSIP resolver implementation using core DNS API. ... This change adds the following: 1. A query set implementation. This is an API that allows queries to be executed in parallel and once all have completed a callback is invoked. 2. Unit tests for the query set implementation. 3. An external PJSIP resolver which uses the DNS core API to do NAPTR, SRV, AAAA, and A lookups. For the resolver it will do NAPTR, SRV, and AAAA/A lookups in parallel. If NAPTR or SRV are available it will then do more queries. And so on. Preference is NAPTR > SRV > AAAA/A, with IPv6 preferred over IPv4. For transport it will prefer TLS > TCP > UDP if no explicit transport has been provided. Configured transports on the system are taken into account to eliminate resolved addresses which have no hope of completing.
