| | | | | | | | | | | | | | | | | Related: https://fedorahosted.org/sssd/ticket/2553 Adds two new functions to the cache_req API: - cache_req_user_by_filter_send - cache_req_group_by_filter_send These functions can be used to retrieve users or groups that match a specified filter. Also renames a variable to avoid constant confusion -- the variable is only used for debug output. Reviewed-by: Pavel Březina <pbrezina@redhat.com>

* negcache: Soften condition for expired entriesLukas Slebodnik2015-05-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Type of timestamp for entries in negative cache is time_t which is number of *seconds* that have elapsed since 1 January 1970. The condition for ttl was to strict so entry could be valid from "ttl-1" to ttl e.g. * ttl is 1 second * entry was stored to negative cache at 1432120871.999639 stored_timestamp = 1432120871 * entry was tested few miliseconds later 1432120872.001293 current_time = 1432120872 Entry was marked as expired becuase result of condition was false stored_timestamp + ttl < current_time 1432120871 + 1 < 1432120872 This is a reason why ./test-negcache sometime fails. It's quite easily reproducible on slow machine or when valgrind was used. sh$ while libtool --mode=execute valgrind ./test-negcache ; do echo OK: done Reviewed-by: Pavel Reichl <preichl@redhat.com>
* responders: reset ncache after domains are discovered during startupJakub Hrozek2015-04-092-8/+38

| | | | | | | | | | | | Originaly, the cache_req used enum sss_dp_acct_type to indicate request type but not all types were implemented.

The function sbus_new_interface() is made static and used directly in sbus_conn_register_iface(). The name was chosen to better describe what the function is doing. That it registers an interface on a given object path. The same interface can be used with different paths so it is not really about adding an interface.

* DP: Remove unused 'force' parameter from the subdomain handlerJakub Hrozek2014-04-221-14/+4
| | | | | | | | | | | | | The force argument was unused and made the code more complex than required. Moreover, the force argument would have made the subdomain handler behave differently than other identity domains -- when the front end decides it's time to update the domains, the back end should just update them. Handling multiple concurrent requests from multiple responders (typically after startup) is handled at the generic back end level (see be_queue_request).

* sbus: Refactor how we export DBus interfacesStef Walter2014-03-142-14/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most importantly, stop using per connection private data. This doesn't scale when you have more than one thing exporting or exported on a connection. Remove struct sbus_interface and expand sbus_conn_add_interface() function. Remove various struct sbus_interface args to connection initialization functions and make callers use sbus_conn_add_interface() directly. The old method was optimized for exporting one interface on a connection. We'll have connections that export zero, one or more interfaces. To export an interface on a DBus server, call sbus_conn_add_interface() from within the sbus_server_conn_init_fn. To export an interface on a DBus client, call sbus_conn_add_interface() after sbus_new_connection() returns. As before struct sbus_interface represents an object exported via DBus. However it is now talloc allocated. One can set instance data on the struct sbus_interface. This instance data is passed to the various handlers and used in their implementation. However, we now have type safe interface exporting in the various high level sss_process_init() sss_monitor_init() and so on. Introspection support was not in use, and is now gone until we implement it using the metadata (future patch).

* sbus: Add struct sbus_request to represent a DBus invocationStef Walter2014-03-142-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct sbus_request represents a request from a dbus client being handled by a dbus server implementation. The struct contains the message, connection and method (and in the future teh property) which is being requested. In the future it will contain caller information as well. sbus_request is a talloc memory context, and is a good place to attach any allocations and memory specific to the request. Each handler accepts an sbus_request. If a handler returns EOK, it is assumed that the handler will finish the request. Any of the sbus_request_*finish() methods can be used to complete the request and send back a reply. sbus_request_return_and_finish() uses the same argument varargs syntax as dbus_message_append_args(), which isn't a great syntax. Document it a bit, but don't try to redesign: The marshalling work (will follow this patch set) will remove the need to use varargs for most DBus implementation code. This patch migrates the monitor and data provider dbus code to use sbus_request, but does not try to rework the talloc context's to use it.
