2010-12-14Reschedule the fd timeout for secondary lookupsStephen Gallagher1-0/+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
2010-12-14Fix timeouts for DNS resolverStephen Gallagher1-1/+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.

2010-04-30Add dns_resolver_timeout optionStephen Gallagher1-1/+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)
2010-04-30Support SRV servers in failoverJakub Hrozek1-5/+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
2010-04-30Sort SRV replies according to RFC 2782Jakub Hrozek2-0/+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.
