* Add authtok utility functions.Simo Sorce2013-01-103-0/+384
| | | | | | These functions allow handling of auth tokens in a completely opaque way, with clear semantics and accessor fucntions that guarantee consistency, proper access to data and error conditions.
* Add function to safely wipe memory.Simo Sorce2013-01-102-0/+18
| | | | | This is useful for wiping passwords, as it prevents the compiler from optimizing out a memset to zero before a free()
* Code can only check for cached passwordsSimo Sorce2013-01-105-36/+45
| | | | | Make it clear to the API users that we can not take arbitrary auth tokens. We can only take a password for now so simplify and clarify the interface.
* Fix sdap reinit.Simo Sorce2013-01-101-82/+89
| | | | | | | | | | | | | | | | This set of functions had a few important issues: 1. the base_dn was always NULL, as the base array was never actually used to construct any DN. This means each function searched the whole database multiple times. It would try to remove SYSDB_USN from all database entries 3 times. Then it would try to find non updated entries another 3 times and delete them, arguably find empty results the last 2 times. 2. Remove use of sysdb_private.h, that header is *PRIVATE* which means it should not be used anywhere but within sysdb. Do this by using existing functions instead of using ldb calls directly. This is important to keep sysdb as conistent and self-contained as possible.
* Use sysdb_search_service() for all svc queriesSimo Sorce2013-01-102-78/+56

* Add sysdb_search_service() helper functionSimo Sorce2013-01-102-0/+63

* AD: Add user as a direct member of his primary groupJakub Hrozek2013-01-091-8/+109
| | | | | | | | | | | | In the AD case, deployments sometimes add groups as parents of the primary GID group. These groups are then returned during initgroups in the tokenGroups attribute and member/memberof links are established between the user and the group. However, any update of these groups would remove the links, so a sequence of calls: id -G user; id user; id -G user would return different group memberships. The downside of this approach is that the user is returned as a group member during getgrgid call as well.
* AD: replace GID/UID, do not add another oneJakub Hrozek2013-01-094-7/+41
| | | | | | | The code would call sysdb_attrs_add_uint32 which added another UID or GID to the ID=0 we already downloaded from LDAP (0 is the default value) when ID-mapping an entry. This led to funky behaviour later on when we wanted to process the ID.
* Revert "Add a default section to a switch-statement"Simo Sorce2013-01-091-12/+8
| | | | | | | This reverts commit d698499602461b98fd56f2d550f80c6cb25f12a9. And adds the correct fix. Also makes the function static,as it is used nowehere else.
* Add a default section to a switch-statementSumit Bose2013-01-091-0/+3
| | | | | Besides adding the missing default this patch suppresses a compiler warning about ret being uninitialized.
* Remove dead netgroup functionsSimo Sorce2013-01-083-419/+0
|
* Remove unhelpful vtable from sss_cacheSimo Sorce2013-01-081-24/+30
| | | | | | | | | Using a vtable like this has various drawacks, including the fact prototypes are not checked by the compiler so the code could silently break and still compile fine (in fact I found this out changing one of the prototypes). A switch statement is also better because it catches if the enum changed and won't risk allowing to access the table out of bounds.
* IPA: Rename IPA_CONFIG_SELINUX_DEFAULT_MAPJakub Hrozek2013-01-083-4/+6
| | | | It is not a map, but a default context. The name should reflect that.
* SELINUX: Process maps even when offlineJakub Hrozek2013-01-081-226/+429
| | | | | Changes the ipa_get_selinux{send,recv} request so that it only delivers data and moves processing to the IPA selinux handler.
* SYSDB: Split a function to read all SELinux mapsJakub Hrozek2013-01-082-23/+49
|
* SYSDB: Remove duplicate selinux definesJakub Hrozek2013-01-083-5/+2

* Refactor gid handling in the PAC responderSumit Bose2013-01-084-105/+238
| | | | | | Instead of using a single array of gid-domain_pointer pairs, Simo suggested to use a gid array for each domain an store it with a pointer to the domain.
* PAC responder: check if existing user differsSumit Bose2013-01-083-13/+64
| | | | | | If some of the Posix attributes of an user existing in the cache differ from the data given in the current PAC the old user entry is drop and a new one is created with the data from the PAC.
* Add tests for get_gids_from_pac()Sumit Bose2013-01-082-0/+257
|
* Use hash table to collect GIDs from PAC to avoid dupsSumit Bose2013-01-081-18/+86
| | | | | | | To avoid duplicated entries in the group list all gids are added to a hash table first. Fixes: https://fedorahosted.org/sssd/ticket/1672
* Translate LDB_ERR_ATTRIBUTE_OR_VALUE_EXISTS to EEXISTSumit Bose2013-01-081-0/+1
| | | | | | | | Currently only the LDB error code indicating that an entry already exists is translated to EEXIST. To make debugging easier and return a better indication of the reason for an error in the logs this patch translates the LDB error code for an already existing attribute or value to EEXIST as well.
* Read remote groups from PACSumit Bose2013-01-081-3/+52
| | | | | | | Read the group membership of the remote domain the user belongs to from the PAC and add them to the cache. Fixes: https://fedorahosted.org/sssd/ticket/1666
* Remote groups do not have an original DN attributeSumit Bose2013-01-081-40/+34
| | | | | | | Groups from subdomains will not have an attribute holding the original DN because in general it will not be available. This attribute is only used by IPA HABC to improve performance and remote groups cannot be used for access control.
* Save domain and GID for groups from the configured domainSumit Bose2013-01-083-17/+47
| | | | | | | | | | Currently users from subdomains can only be members of groups from the configured domain and to access those groups a pointer to the domain struct of the configured domain is used. This patch sets the dom_grp member of struct pac_grp to point to the domain struct of the configured for groups from this domain. This is a first step to allow group membership for groups from subdomains as well. For those groups a pointer to the related subdomain structure will be saved.
* Always get user data from PACSumit Bose2013-01-081-7/+7
| | | | | | | Currently some user specific data from the PAC is only read when the user is not already in the cache. Since some of this information is needed later on, e.g. the domain SID the user belongs to, with this patch the data is read always from the PAC.
* Update domain ID for local domain as wellSumit Bose2013-01-081-2/+14
| | | | | | | Currently only the flat name of the configured domain is updated if it is not already set. This patch updates the domain ID as well. This is typically the case when trust support is enabled on the server side while sssd is running.
* IDMAP: add sss_idmap_smb_sid_to_unix()Sumit Bose2013-01-082-0/+39
| | | | | To avoid a conversion on the caller side a new call is added to libsss_idmap which converts a Samba dom_sid structure to a Posix ID.
* Add find_domain_by_id()Sumit Bose2013-01-083-0/+91
| | | | | | | Currently domains can only be searched by name in the global domain list. To make it easier to find the domain for a given SID find_domain_by_id() which returns a pointer to the domain or subdomain entry in the global domain list if a matching id was found.
* Use struct pac_grp instead of gid_t for groups from PACSumit Bose2013-01-084-26/+36
| | | | | To be able to handle groupmemberships from other domains more data than just the gid must be kept for groups given in the PAC.
* Potential resource leak in sss_nss_mc_get_recordJakub Hrozek2013-01-081-0/+1
| | | | https://fedorahosted.org/sssd/ticket/1748
* sudo smart refresh: fix debug messagePavel Březina2013-01-071-1/+1

* sudo smart refresh: do not include usn in filter if no valid usn is knownPavel Březina2013-01-071-5/+12
| | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1736 When there are no rules during first refresh, we don't have valid USN value. We use 0 in this case, but it turned out that OpenLDAP takes it as invalid time format (if modifyTimestamp is used instead of USN) and thus returns no records. Now we don't include USN/modifyTimestamp attribute in the filter if such situasion occurs.
* memcache: make MC_PTR_TO_SLOT() more readablePavel Březina2013-01-071-2/+1

* memcache: add macro that validates record lengthPavel Březina2013-01-072-2/+7
|
* sss_userdel and sss_groupdel with use_fully_qualified_namesMichal Zidek2013-01-071-15/+50
| | | | | If use_fully_qualified_names is used, we need to pass fqdn to sss_mmap_cache_*_invalidate.
* SYSDB: split sysdb_add_userOndrej Kos2013-01-071-125/+176
| | | | | The function itself was very long (more than 300 lines) and hard to read, this patch splits it to three logical blocks.
* SYSDB: Modify ghosts in permissive modeOndrej Kos2013-01-071-1/+33
| | | | | | | | | https://fedorahosted.org/sssd/ticket/1714 The attempt to delete all ghosts for users name and aliases was failing, resulting into failure of whole user-add operation. In permissive mode, the attempts to delete non-existent entries are not interpreted as error.
* Search for SHORTNAME$@REALM instead of fqdn$@REALM by defaultJakub Hrozek2013-01-071-3/+35
| | | | | | | | The search was intended for the AD provider mostly, but keytabs coming from AD via samba don't contain fqdn$@REALM but rather uppercased SHORTNAME$@REALM https://fedorahosted.org/sssd/ticket/1740
* Fix tevent_req style for sdap_async_sudo.Simo Sorce2013-01-071-22/+22
| | | | | | Use correct name for _done() function from the caller. Remove unneded initializzations to NULL for a lot of variables hat are going to be assigned as the first thing done in the functions.
* Remove redundant definition.Simo Sorce2013-01-072-2/+1
| | | | | We had 2 defines for the same class. Consolidate and remove confusion.
* Remove unused headerSimo Sorce2013-01-061-1/+0
|
* sss_cache: fqdn not acceptedMichal Zidek2013-01-041-14/+149
| | | | | | sss_cache did not accept fully quaified domain names. https://fedorahosted.org/sssd/ticket/1620
* LDAP: initialize refresh function handlerOndrej Kos2013-01-041-1/+1
|
* let krb5_backup_kpasswd failover workPavel Březina2013-01-021-2/+2
| | | | https://fedorahosted.org/sssd/ticket/1735
* failover: Protect against empty host namesMichal Zidek2013-01-0211-102/+174
| | | | | | | | | | Added new parameter to split_on_separator that allows to skip empty values. The whole function was rewritten. Unit test case was added to check the new implementation. https://fedorahosted.org/sssd/ticket/1484
* set ret to EOK after for loop in sdap_sudo_purge_sudoersPavel Březina2013-01-021-0/+2
| | | | | | | | | | If we are unable to delete some rule from cache we print a debug message and ignore the error. Thus we should set ret to EOK after the for loop otherwise we return whether the last rule was deleted successfully or not. This also removes compilation warning that ret may be used uninitialized (when we don't go inside the loop at all).
* mmap cache: invalidate cache on fatal errorSimo Sorce2012-12-203-10/+30
| | | | | | | | | | If a fatal EFAULT error is returned by the internal function that frees used memory invalidate the whole cache and reinit it. This way we avoid further corruption and insure clients see consistent data. Also insure we use the right context in init() and we use talloc_zfree() in reinit so that if the init() later fails we do not leave around a pointer to free memory in the callers.
* Carefully check records when forcibly invalidatingSimo Sorce2012-12-202-20/+105
| | | | | | | | | | | | We should never try to invalidate an already invalid record as internal pointers will not be consistent. Carefully test that the record really is valid when we are fishing for free space, and properly invalidate records or return a fatal error if something goes wrong. In order to make the code more robust always invalidate the whole data space on initialization by setting all bits to 1, and make sure to invalidate the whole last allocated slot by converting rec->len to the number of slots instead of just the space used.
* Update free table when records are invalidated.Simo Sorce2012-12-201-14/+23
| | | | | We were holding up slots when entries were invalidated directly an not through our primitive garbage collection scheme.
