* Fix double free issueSumit Bose2010-10-261-2/+2

* Always use talloc_zero() to allocate cmdctxSumit Bose2010-10-262-3/+3
|
* 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.
* sysdb interface for adding fake usersJakub Hrozek2010-10-151-1/+1

* sysdb interface for adding incomplete groupsJakub Hrozek2010-10-151-1/+1
| | | | Useful for optimizing the initgroups operation.

* Add netgroup support to the NSS responderStephen Gallagher2010-10-137-2/+922
|
* Split out some helper functions for the NSS responderStephen Gallagher2010-10-132-83/+147
| | | | | Create a new private header and make some functions available for other object files.
* Add negative cache features for netgroupsStephen Gallagher2010-10-132-0/+39
|
* 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.
* Honor filter_users in PAMStephen Gallagher2010-06-173-10/+47
|
* Move setup of filter_users and filter_groups to negcache.cStephen Gallagher2010-06-173-187/+220
| | | | | Creates a new function - sss_ncache_prepopulate() - that can be shared with other responders, such as PAM.
* Refactor the negative cacheStephen Gallagher2010-06-175-57/+57
| | | | | Rename functions from nss_ncache_* to sss_ncache_* Move negative cache to responder/common and rename as negcache.c/h
* Ensure that all domains are checked for users/groupsStephen Gallagher2010-06-171-3/+15
| | | | | | | There was a bug in the negative cache checks (probably a leftover from when filter_users was global-only) that meant that if a user was filtered out of a domain, the remaining domains would not be checked for that user. (Same for groups/initgroups)
* Properly null-terminate socket pathStephen Gallagher2010-06-141-2/+4
| | | | https://fedorahosted.org/sssd/ticket/540
* Check the correct variable for NULL after creating timerStephen Gallagher2010-06-101-1/+1
| | | | | | | | | In several places, we were creating a new timer and assigning it to the tev variable, but then we were checking for NULL from the te variable (which, incidentally, is guaranteed never to be NULL in this situation) https://fedorahosted.org/sssd/ticket/523
* Remove dead code from the PAM responderJakub Hrozek2010-06-062-13/+0

* Add support for delayed kinit if offlineSumit Bose2010-05-261-1/+1
| | | | | | | If the configuration option krb5_store_password_if_offline is set to true and the backend is offline the plain text user password is stored and used to request a TGT if the backend becomes online. If available the Linux kernel key retention service is used.
* Use SO_PEERCRED on the PAM socketSumit Bose2010-04-162-1/+55
| | | | | | | | | | | | | | | | | This is the second attempt to let the PAM client and the PAM responder exchange their credentials, i.e. uid, gid and pid. Because this approach does not require any message interchange between the client and the server the protocol version number is not changed. On the client side the connection is terminated it the responder is not run by root. On the server side the effective uid and gid and the pid of the client are available for future use. The following additional changes are made by this patch: - the checks of the ownership and the permissions on the PAM sockets are enhanced - internal error codes are introduced on the client side to generate more specific log messages if an error occurs
* Revert "Add better checks on PAM socket"Sumit Bose2010-04-162-140/+1

|
* Adjust fill_pwent and fill_grentSimo Sorce2010-04-121-13/+13
| | | | | | | | | fill_pwent should return the number of users actually processed. Otherwise in case of a recoverable error we may end up skipping a large chunk of users. fill_grent doesn't need to distinguish between number of entries and number of groups to process since we started adding memberuid. Remove remnants that are not useful anymore.

* Fix warnings from -Wmissing-field-initializersSumit Bose2010-03-252-18/+18
| | | | This patch removes some tab-indentations from pamsrv.c, too.

* Fixes for client communicationSumit Bose2010-03-172-9/+17
| | | | | | | - catch all errors of send() and recv(), not only EAGAIN - check if send() or recv() return EWOULDBLOCK or EINTR - remove unused parameter from client_send() and client_recv() - fix a debugging message
* Fixed buffer alignment in exchange_credentials().George McCollister2010-03-151-3/+7
| | | | | | buf needs to be 32 bit aligned on ARM. Also made the fix on the server side. Signed-off-by: George McCollister <George.McCollister@gmail.com>
* Properly handle dbus send attempts on a closed connectionStephen Gallagher2010-03-152-44/+15
| | | | | | | | dbus_connection_send_with_reply() will report success and return a NULL pending_reply when the connection is not open for communication. This patch creates a new wrapper around dbus_connection_send_with_reply() to properly detect this condition and report it as an error.
* Add better checks on PAM socketSumit Bose2010-03-112-1/+136
| | | | | - check if the public socket belongs to root and has 0666 permissions - use a SCM_CREDENTIALS message if available
* Make filter_users and filter_groups also per-domainJakub Hrozek2010-03-081-13/+109
| | | | Fixes: #290
* Reopen logs when SIGHUP is caughtJakub Hrozek2010-03-082-0/+2
| | | | | | | | Upon receiving SIGHUP, the monitor signals all services to reopen their debug logs. It is also possible to signal individual services to reopen their particular files. Fixes: #332
* Fixed alignment problems in nss client/serverGeorge McCollister2010-03-081-6/+5
| | | | | | | | I fixed a handful of alignment problems in sss_client and nss responder. Enumerating group and passwd with getgrent and getpwent now works correctly on ARM. Signed-off-by: George McCollister <georgem@novatech-llc.com>
* Add forgotten \n in DEBUG statementsMartin Nagy2010-03-045-9/+9
| | | | | | Logs from confdb with missing '\n' in the DEBUG statements annoyed me so I decided to fix them. I also made a quick grep through the code and found other places so I fixed them too.
