* File descriptor leak in nss responder.sssd-1.9.2-112.el6Michal Zidek2013-08-091-18/+43
| | | | | | | | | File descriptors leaked every time sss_mmap_cache_reinit was called and also the old memory cache was still maped in memory (munmap was not called). This patch adds destructor for memory cache context to call close() and munmap() automaticly. https://fedorahosted.org/sssd/ticket/1826
* Debug message in sss_mc_create_file.Michal Zidek2013-08-091-0/+5
| | | | | | This patch adds debug message for the case if sssd fails to open old mc file for some other reason than the file does not exist.

* Every time use permissive control in function memberof_mod.sssd-1.9.2-109.el6Lukas Slebodnik2013-08-091-0/+7
| | | | | | | | | | | Storing cyclic groups into sysdb can cause adding ghost members, which has already been stored. Function ldb_modify will fail with error [Attribute or value exists]. With permisive control, duplicated attributes will be skipped as if it was never added. https://fedorahosted.org/sssd/ticket/1846

* Display the last grace warning, toosssd-1.9.2-107.el6Jakub Hrozek2013-08-092-3/+3
| | | | | | | Due to a comparison error, the last warning when an LDAP password was in its grace period was never displayed. https://fedorahosted.org/sssd/ticket/1890
* Do not call sss_cmd_done in function check_cache.sssd-1.9.2-105.el6Lukas Slebodnik2013-08-081-6/+0
| | | | | | | | Function sysdb_getpwnam return more results than 1 and therefore sss_cmd_done was called. Inside of function sss_cmd_done memory was freed, but this freed memory was used in caller functions, therefore sssd crashed. https://fedorahosted.org/sssd/ticket/1980

* sudo responder: use fully qualified name for subdomain userssssd-1.9.2-103.el6Pavel Březina2013-08-081-1/+1
| | | | | | | | | https://fedorahosted.org/sssd/ticket/1912 Patch that converts subdomain usernames into fully qualified format made it to the 1.9 branch but sudo wasn't aware of it. This patch changes sysdb_getpwnam call to sysdb_subdom_getpwnam which converts username into fqn if the domain is subdomain.

* sudo responder: use different callback for oob refreshsssd-1.9.2-100.el6Pavel Březina2013-08-081-6/+8
| | | | | | | | | https://fedorahosted.org/sssd/ticket/1693 Since we don't care about returned values from out of band refresh, we do not need to set callback data. However, this caused talloc to abort as it considers it as type mismatch when called from tevent_req_callback_data().
* MAN: Clarify the min_id/max_id limits furthersssd-1.9.2-99.el6Jakub Hrozek2013-08-081-0/+4
| | | | | | | | | https://fedorahosted.org/sssd/ticket/2005 Some users were confused by our description of min_id/max_id and thought the limits only applied to returning entries from the NSS responder. However, the limits are actually enforced on the back end side, so the entries are not even saved to cache.
* IPA: Do not download or store the member attribute of host groupssssd-1.9.2-98.el6Jakub Hrozek2013-08-082-2/+0
| | | | | | | | https://fedorahosted.org/sssd/ticket/1806 The IPA provider attempted to store the original value of member attribute to the cache. That caused the memberof plugin to process the values which was really CPU intensive.
* NSS: Clear cached netgroups if a request comes in from the sss_cachesssd-1.9.2-97.el6Lukas Slebodnik2013-08-084-0/+55
| | | | | | | In order for sss_cache to work correctly, we must also signal the nss responder to invalidate the hash table requests. https://fedorahosted.org/sssd/ticket/1759
* NSS: allow removing entries from netgroup hash tableLukas Slebodnik2013-08-083-1/+32
| | | | | | | | | There is a timed desctructor in the nss responder that, when the entry timeout passes, removes the netgroup from the hash table while the netgroup is freed. This patch adds a hash delete callback so that if the netgroup is removed from the hash table with hash_delete, its hash table pointer will be invalidated. Later, when the entry is being freed, the destructor won't attempt to remove it from the hash table.

* Allocate PAM DP request data on responder context1.9.2-92Jakub Hrozek2013-07-253-5/+54
| | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1869 Currently the private data passed to the PAM request is a structure allocated on the client context. But in the odd case where the back end would be stopped or stuck until the idle timeout hits, the DP callback would access data that were freed when the client timed out. This patch introduces a new structure allocated on responder context, whose only purpose is to live as long as the request is active.
* autofs: fix invalid header 'number of entries' in packet1.9.2-91Pavel Březina2013-05-301-1/+5
| | | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1739 Pointer to packet body may change while filling packet with autofs mount points. As a consequence, we sometimes wrote the number of entries into invalid body and we recieved an arbitrary number on the client side. If the number was 0, there were some skipped entries. If the number was greater than 0, everything worked correctly, because we iterate through the cached entries until we reach packet length - we don't compare to the number.
* Only try to relink ghost users if we're not enumerating1.9.2-90Jakub Hrozek2013-05-302-4/+16
| | | | | | | | https://fedorahosted.org/sssd/ticket/1893 When SSSD is not enumerating (which is the default), we are trying to link any "ghost" entries with a newly created user entry. However, when enumeration is on, this means a spurious search on adding any user.
* LDAP: do not invalidate pointer with realloc while processing ghost users1.9.2-89Jakub Hrozek2013-05-301-3/+13
| | | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1799 One peculiarity of the sysdb_attrs_get_el interface is that if the attribute does not exist, then the attrs array is reallocated and the element is created. But in case other pointers are already pointing into the array, the realloc might invalidate them. Such case was in the sdap_process_ghost_members function where if the group had no members, the "gh" pointer requested earlier might have been invalidated by the realloc in order to create the member element.
* Fix simple access group control in case-insensitive domains1.9.2-88Jakub Hrozek2013-04-152-18/+11
| | | | | | | | | https://fedorahosted.org/sssd/ticket/1880 In the simple access provider, we need to only canonicalize user names when comparing with values in the ACL, not when searching the cache. The sysdb searches might do a base search with a DN constructed with the username which fails if the username is lower case.
* ldap: Fallback option for rfc2307 schemaSimo Sorce2013-04-1513-11/+227
| | | | | | | | | | | Add option to fallback to fetch local users if rfc2307is being used. This is useful for cases where people added local users as LDAP members and rely on these group memberships to be maintained on the local host. Disabled by default as it violates identity domain separation. Ticket: https://fedorahosted.org/sssd/ticket/1020
* Resolve GIDs in the simple access providerJakub Hrozek2013-04-154-303/+1020
| | | | | | | | | | | | | | Changes the simple access provider's interface to be asynchronous. When the simple access provider encounters a group that has gid, but no meaningful name, it attempts to resolve the name using the be_file_account_request function. Some providers (like the AD provider) might perform initgroups without resolving the group names. In order for the simple access provider to work correctly, we need to resolve the groups before performing the access check. In AD provider, the situation is even more tricky b/c the groups HAVE name, but their name attribute is set to SID and they are set as non-POSIX
* Do not compile main() in DP if UNIT_TESTING is definedJakub Hrozek2013-04-151-0/+2
| | | | | | | | | | | The simple access provider unit tests now need to link against the Data Provider when they start using the be_file_account_request() function. But then we would start having conflicts as at least the main() functions would clash. If UNIT_TESTING is defined, then the data_provider_be.c module does not contain the main() function and can be linked against directly from another module that contains its own main() function
* Add unit tests for simple access test by groupsJakub Hrozek2013-04-151-32/+253
| | | | | | | I realized that the current unit tests for the simple access provider only tested the user directives. To have a baseline and be able to detect new bugs in the upcoming patch, I implemented unit tests for the group lists, too.
* Provide a be_get_account_info_send functionJakub Hrozek2013-04-152-19/+149
| | | | | | | | | | | | | | In order to resolve group names in the simple access provider we need to contact the Data Provider in a generic fashion from the access provider. We can't call any particular implementation (like sdap_generic_send()) because we have no idea what kind of provider is configured as the id_provider. This patch splits introduces the be_file_account_request() function into the data_provider_be module and makes it public. A future patch should make the be_get_account_info function use the be_get_account_info_send function.

| | | | | | | | | https://fedorahosted.org/sssd/ticket/1783 When dn in member attribute is invalid (e.g. rdn instead of dn) or it is outside of configured search bases, we might hit a situation when tevent_req is marked as done before any callback could be attached on it.

* TOOLS: Use file descriptor to avoid races when creating a home directoryJakub Hrozek2013-01-234-354/+364
| | | | | | | | | | | When creating a home directory, the destination tree can be modified in various ways while it is being constructed because directory permissions are set before populating the directory. This can lead to file creation and permission changes outside the target directory tree, using hard links. This security problem was assigned CVE-2013-0219 https://fedorahosted.org/sssd/ticket/1782
* TOOLS: Use openat/unlinkat when removing the homedirJakub Hrozek2013-01-231-42/+41
| | | | | | | | | | The removal of a home directory is sensitive to concurrent modification of the directory tree being removed and can unlink files outside the directory tree. This security issue was assigned CVE-2013-0219 https://fedorahosted.org/sssd/ticket/1782

* sudo responder: change num_rules type from size_t to uint32_tPavel Březina2013-01-227-26/+26
| | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1779 2^32 should be enough to store sudo rules. size_t type was causing troubles on big endian architectures, because it wasn't used correctly in combination with D-Bus. Resolved Conflicts: src/responder/sudo/sudosrv_get_sudorules.c
* Convert the value of pwd_exp_warning to secondsJakub Hrozek2013-01-221-5/+6
| | | | | | | | When read from the domain section, the pwd_expiration_warning was properly converted to seconds from days, but not the pam_pwd_expiration_warning set in the [pam] section. https://fedorahosted.org/sssd/ticket/1773
* fix backend callbacks: remove callback properly from dlistPavel Březina2013-01-221-6/+18
| | | | | | | | https://fedorahosted.org/sssd/ticket/1776 Although cb->list got updated when the callback is removed, this change did not propagate to be_ctx->*_cb_list which caused dlist having invalid records.
* TOOLS: invalidate parent groups in memory cache, tooJakub Hrozek2013-01-214-8/+71

* LDAP: Compare lists of DNs when saving autofs entriesJakub Hrozek2013-01-213-137/+173
| | | | | | | | | | | | https://fedorahosted.org/sssd/ticket/1758 The autofs entries do not have the key as an unique identifier, but rather the full (key, value) tuple as some keys have a special meaning, such as the direct mount key (/-) and may be present in a single map multiple times. Comparing the full DN that contains both the key and the value will allow for working updates if either key or value changes.
* Invalidate user entry even if there are no groupsJakub Hrozek2013-01-162-11/+8
| | | | | | | | | Related to https://fedorahosted.org/sssd/ticket/1757 Previously we would optimize the mc invalidate code for cases where the user was a member of some groups. But if the user was removed from the server while being in memory cache, we would only invalidate the mc record if he was a member of at least one supplementary group.
* NSS: invalidate memcache user entry on initgr, tooJakub Hrozek2013-01-161-0/+11
| | | | | | | | | https://fedorahosted.org/sssd/ticket/1757 When the user entry was missing completely after initgroups, we would never invalidate the user entry from cache. This led to dangling cache entried in memory cache if the user was removed from the server while still being in memory cache.

* LDAP: avoid complex realloc logic in save_rfc2307bis_group_membershipsJakub Hrozek2013-01-151-12/+4
| | | | | | | | | https://fedorahosted.org/sssd/ticket/1761 The function tried to be smart and realloc only when needed, but that only lead to hard-to find bugs where the logic would not allocate the proper space. Remove the reallocation and prefer readability over speed in this case.
