2012-09-13FO: Check server validity before setting statusJakub Hrozek1-14/+13
The list of resolved servers is allocated on the back end context and kept in the fo_service structure. However, a single request often resolves a server and keeps a pointer until the end of a request and only then gives feedback about the server based on the request result. This presents a big race condition in case the SRV resolution is used. When there are requests coming in in parallel, it is possible that an incoming request will invalidate a server until another request that holds a pointer to the original server is able to give a feedback. This patch simply checks if a server is in the list of servers maintained by a service before reading its status. https://fedorahosted.org/sssd/ticket/1364

2012-08-01Primary server support: basic support in failover codeJan Zeleny1-28/+187
Now there are two list of servers for each service. If currently selected server is only backup, then an event will be scheduled which tries to get connection to one of primary servers and if it succeeds, it starts using this server instead of the one which is currently connected to.

2011-01-21Allow fallback to SSSD domainStephen Gallagher1-2/+4
For backwards-compatibility with older versions of the SSSD (such as 1.2.x), we need to be able to have our DNS SRV record lookup be capable of falling back to using the SSSD domain name as the DNS discovery domain. This patch modifies our DNS lookups so that they behave as follows: If dns_discovery_domain is specified, it is considered authoritative. No other discovery domains will be attempted. If dns_discovery_domain is not specified, we first attempt to look up the SRV records using the domain portion of the machine's hostname. If this returns "NOTFOUND", we will try performing an SRV record query using the SSSD domain name as the DNS discovery domain. https://fedorahosted.org/sssd/ticket/754
2010-12-01Run checks before resetting offline stateSumit Bose1-0/+5
Before setting the backend to online during a reset offline request the check_online method if the ID provider is called. If the check_online method returns that the ID provider is still not reachable the backend stays offline. Otherwise the backend is switched to online and the related callbacks are run. Additionally the check online test is called during the res_init request because a change in /etc/resolve.conf might also make a server reachable which was assumed offline before.

2010-07-09Add an interface to try next fail-over server after connection to the active ↵eindenbom1-45/+45
server was unexpectedly dropped.
2010-07-09Added an interface to query number of configured (and currently resolved ↵eindenbom1-0/+21
through SRV records) failover servers.
2010-06-30Add dns_discovery_domain optionJakub Hrozek1-1/+12
The service discovery used to use the SSSD domain name to perform DNS queries. This is not an optimal solution, for example from the point of view of authconfig. This patch introduces a new option "dns_discovery_domain" that allows to set the domain part of a DNS SRV query. If this option is not set, the default behavior is to use the domain part of the machine's hostname. Fixes: #479
2010-05-27Add run_callbacks flagSumit Bose1-2/+23
2010-05-07Use service discovery in backendsJakub Hrozek1-0/+32
Integrate the failover improvements with our back ends. The DNS domain used in the SRV query is always the SSSD domain name. Please note that this patch changes the default value of ldap_uri from "ldap://localhost" to "NULL" in order to use service discovery with no server set.
2010-04-30Add dns_resolver_timeout optionStephen Gallagher1-1/+9
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)
2010-02-22Restrict family lookupsJakub Hrozek1-3/+49
Adds a new option that tells resolver which address family to prefer or use exclusively. Fixes: #404
