* resolv: Do not try to free addrinfo in case of errorLukas Slebodnik2014-05-201-1/+2
| | | | | | | | | | | We should call freeaddrinfo only in situation if getaddrinfo succeeds. It is not specified in RFC2553 the behaviour of calling freeaddrinfo with the NULL argument. It is more portable to do not rely on undocumented behaviour of glibc. http://www.ietf.org/rfc/rfc2553.txt [Page 28] Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>

* dyndns: New option dyndns_update_ptrJakub Hrozek2013-05-032-4/+7
| | | | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1832 While some servers, such as FreeIPA allow the PTR record to be synchronized when the forward record is updated, other servers, including Active Directory, require that the PTR record is synchronized manually. This patch adds a new option, dyndns_update_ptr that automatically generates appropriate DNS update message for updating the reverse zone. This option is off by default in the IPA provider. Also renames be_nsupdate_create_msg to be_nsupdate_create_fwd_msg

* Provide TTL structure names for c-ares < 1.7Jakub Hrozek2011-06-161-0/+8
| | | | | | | | | | | https://fedorahosted.org/sssd/ticket/898 In c-ares 1.7, the upstream renamed the addrttl/addr6ttl structures to ares_addrttl/ares_addr6ttl so they are in the ares_ namespace. Because they are committed to stable ABI, the contents are the same, just the name changed -- so it is safe to just #define the new name for older c-ares version in case the new one is not detected in configure time.

* Use safe alignment macros for in-tree SRV record parsingJakub Hrozek2011-04-121-3/+3
| | | | | | The in-tree SRV record parsing is used with very old c-ares libraries that don't implement the parsing themselves (c-ares < 1.7, used in e.g. RHEL5)
* Reschedule the fd timeout for secondary lookupsStephen Gallagher2010-12-141-0/+4
| | | | | | | | | | | We were unscheduling the timeout handler after the first lookup (A or AAAA) returned, but not rescheduling it if we went on to check the secondary record type. This resulted in the resolver never returning a result for the secondary lookup, which can mean that logins/screen unlocks after VPN drop or suspend/resume might never complete. Fixes https://fedorahosted.org/sssd/ticket/729
* Fix timeouts for DNS resolverStephen Gallagher2010-12-141-1/+1
| | | | | | | options.tries specifies the number of retries. Setting this to zero means to try exactly once. Previously we were always trying twice (internally). We want to simply honor the SSSD configuration and fail over to the next server (or go offline) after one try.
* Internal DNS resolver should check /etc/hostsJakub Hrozek2010-11-241-0/+2
| | | | https://fedorahosted.org/sssd/ticket/686
* Add dns_resolver_timeout optionStephen Gallagher2010-04-301-1/+5
| | | | | | We had a hard-coded timeout of five seconds for DNS lookups in the async resolver. This patch adds an option 'dns_resolver_timeout' to specify this value (Default: 5)
* Support SRV servers in failoverJakub Hrozek2010-04-301-5/+5
| | | | | | | | | | | | | | | Adds a new failover API call fo_add_srv_server that allows the caller to specify a server that is later resolved into a list of specific servers using SRV requests. Also adds a new failover option that specifies how often should the servers resolved from SRV query considered valid until we need a refresh. The "real" servers to connect to are returned to the user as usual, using the fo_resolve_service_{send,recv} calls. Make SRV resolution work with c-ares 1.6
* Sort SRV replies according to RFC 2782Jakub Hrozek2010-04-302-0/+248
| | | | | | | | | | RFC 2782 defines a way to sort replies to a SRV query. In short, the algorithm sorts all replies by priority and then does a weight-based selection for every priority level. For details, please see the sections "Usage rules" for overview of the algorithm and section "The 'Weight' field" for description on the weight selection.
