2012-01-23DP: Fix bugs in sss_dp_get_account_intStephen Gallagher1-0/+1
The conversion to the tevent_req style introduced numerous bugs related to memory management of the various client requests. In some circumstances, this could cause memory corruption and segmentation faults in the NSS responder. This patch makes the following changes: 1) Rename the internal lookup from subreq to sidereq, to indicate that it is not a sub-request of the current lookup (and therefore is not cancelled if the current request is). 2) Change the handling of the callback loops since they call tevent_req_[done|error], which results in them being freed (and therefore removed from the cb_list. This was the source of the memory corruption that would occasionally result in dereferencing an unreadable request. 3) Remove the unnecessary sss_dp_get_account_int_recv() function and change sss_dp_get_account_done() so that it only frees the sidereq. All of the waiting processes have already been signaled with the final results from sss_dp_get_account_int_done()
2012-01-21RESPONDER: Extend sss_dp_account_send() to include extra dataStephen Gallagher1-4/+4
Some NSS maps such as 'services' require more values to be passed to the data provider than just the name or ID. In these cases, we will amend an optional component to filter value to pass to the data provider backend.

2011-08-15sysdb refactoring: deleted domain variables in sysdb APIJan Zeleny1-7/+7

There may be users in LDAP that have a valid but unwelcome shell set in their account. This adds a blacklist of shells that should always be replaced by the fallback_shell. Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>

Useful for optimizing the initgroups operation.
2010-10-13Add netgroup support to the NSS responderStephen Gallagher1-2/+9
2010-10-13Split out some helper functions for the NSS responderStephen Gallagher1-83/+17
Create a new private header and make some functions available for other object files.
2010-10-13Require explicit setting of callback context for check_cacheStephen Gallagher1-7/+13
Previously, it was implicitly using the nss_dom_ctx, but there are situations where we would want to send a different private context
2010-09-22Initgroups on a non-cached user should go to the data providerStephen Gallagher1-1/+2
We were accidentally returning an error when sysdb_getpwnam() returned zero results internally in sysdb_initgroups(). The correct behavior here is to return EOK and a result object with zero entries.
2010-09-08Handle multiple simultaneous enumeration requestsStephen Gallagher1-289/+706
Previously, if a second enumeration request arrived while one was already being processed, each process would receive only a subset of the total number of available users or groups. This is because we were maintaining the response object as a global value in the NSS responder. The second request would come in, see that the data set was already populated, and start reading from wherever the cursor was currently pointed. With this patch, we now move the cursor to the client context instead of the global NSS context. Additionally, this patch completely rewrites the approach to enumerations in the tevent_req style. This makes it much easier to follow in the code. In order to ensure that a slow or malicious client cannot hold onto a reference for the setent result object indefinitely, we set an expiration on the object. We use the enum_cache_timeout here, since that is an appropriate value. If the timeout fires during the normal operation of the get*ent() loop of a client program, we will save the current values of the read index so that we can resume as soon as the object has been refreshed by an implicit setent call. Instead of deleting the enumeration result object immediately after the last in-progress client has read it, we'll keep the object around for the lifetime of enum_cache_timeout. This way, additional clients making enumeration requests can still access the results in-memory.
