* RESPONDER: Fix segfault in sss_packet_send()sssd-1.5.1-62.el6Stephen Gallagher2011-10-251-0/+5
| | | | | | | | | There are several places (all error-handling) where sss_cmd_done() is called with no response packet created. As a short-term solution, we need to check whether the packet is NULL and simply return EINVAL. client_send() (the consumer) will then forcibly disconnect the client (which will return PAM_SYSTEM_ERR to the client).

| | | | | | | | | | | | 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.

* Add missing name to struct getent_ctx for missing netgroupSumit Bose2011-03-071-4/+13
| | | | | | | | | | https://fedorahosted.org/sssd/ticket/817 Refactor set_netgroup_entry() To avoid wrong or missing netgroup names in the getent_ctx destructor set_netgroup_entry() now takes the name out of the getent_ctx struct instead of using a separate argument.
* Perform initgroups lookups for all domainsStephen Gallagher2011-02-211-3/+5
| | | | | | | | | | Previously, we were setting the client context PAM lookup timeout after the first domain replied. However, if the user wasn't a member of the first domain, their information wasn't being updated. This patch ensures that we only set this timeout after the user has been found or all domains were searched.
* Perform initgroups lookup for PAMStephen Gallagher2011-01-211-1/+3
| | | | | Previously we were only looking up the user, but we need to make sure that all groups are available for use by access providers.
* Use DEFAULT_PAM_VERBOSITY if config value cannot be retrievedSumit Bose2011-01-191-1/+1

* Add pam_pwd_expiration_warning config optionSumit Bose2011-01-191-12/+47
|
* Fix missing hash table bugStephen Gallagher2011-01-141-0/+1
| | | | | | | When the automatic cleanup happened, if the netgroup had been created with no contents (to indicate an unknown netgroup), we weren't saving the hash table address and the talloc_free() was failing.
* Validate user supplied size of data itemsSumit Bose2011-01-111-76/+75
| | | | | | Specially crafted packages might lead to an integer overflow and the parsing of the input buffer might not continue as expected. This issue was identified by Sebastian Krahmer <krahmer@suse.de>.
* Remove unused enumeration cache timeout checksSumit Bose2011-01-063-33/+2
| | | | | The existence of the getent_ctx is used to track the enumeration cache timeout.
* Post enumeration tevent request if neededSumit Bose2011-01-062-8/+43

* Update the ID cache for any PAM requestStephen Gallagher2010-12-224-8/+23
| | | | | | | | Also adds an option to limit how often we check the ID provider, so that conversations with multiple PAM requests won't update the cache multiple times. https://fedorahosted.org/sssd/ticket/749
* Ensure ID is checked in all domains for PAMStephen Gallagher2010-12-221-0/+2
| | | | | | | Previously, this was initialized to zero, so the first domain in the list wouldn't be checked for ID updates in pam_check_user_search. This initializes the first domain to check the provider.

* Introduce pam_verbosity config optionSumit Bose2010-11-151-11/+90
| | | | | | | | | | | Currently we display all PAM messages generated by sssd to the user. But only some of them are important and others are just some useful information. This patch introduces a new option to the PAM responder which controls what kind of messages are displayed. As an example the 'Authenticated with cached credentials' message is used. This message is only displayed if pam_verbosity=1 or if there is an expire date.

* Remove all nss requests after a reconnectSumit Bose2010-10-263-1/+26
| | | | | | | Currently we do not handle the open nss request after a reconnect and wait until they timeout (which is a couple of minutes!). This patch adds a handler that terminates all requests after a reconnect. Then responder will return matching cache entries or nothing.

* Require explicit setting of callback context for check_cacheStephen Gallagher2010-10-131-7/+13
| | | | | Previously, it was implicitly using the nss_dom_ctx, but there are situations where we would want to send a different private context
* Initgroups on a non-cached user should go to the data providerStephen Gallagher2010-09-221-1/+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.
* Handle multiple simultaneous enumeration requestsStephen Gallagher2010-09-082-289/+717
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Dead assignments cleanup in NSS responderJan Zeleny2010-09-082-7/+7
| | | | | | Various dead assignments were deleted, some return value inspections were added. Ticket: #588
* Move crypto functions into its own subdirJakub Hrozek2010-09-081-1/+1
| | | | | | A refactoring patch that creates a common util/crypto subdir with per-implementation subdirectories for each underlying crypto library supported by SSSD.
