2013-04-21Refactoring: remove duplicated code in nss responderSumit Bose2-622/+240
Different user and group lookup requests used nearly identical code, this patch unifies some of the related code paths.
2013-04-21Fix and rename get_my_domain_data()Sumit Bose3-12/+14
The task of get_my_domain_data() is to read some information about the configured domain from the cache. While the sysdb interface was redesigned some changes changed the behaviour so that the data of the domain of the current request was read. If this domain is a sub-domain the wrong data was read. As a result group-memberships of the configured domain were not taken into account. The original code didn't made it easy to see that always the parent domain should be used here, because there was no comment indication this and the function name get_my_domain_data() didn't made it clear either. Additionally to fixing the issue this patch also adds a comment and rename the function to get_parent_domain_data(). Fixes https://fedorahosted.org/sssd/ticket/1888
2013-04-17Inform about function duplication.Michal Zidek1-0/+3
sss_mc_set_recycled is a static function, that should not be used outside nsssrv_mmap_cache.c. The sss_cache tool is an exception, because in the case when sssd is not running, sss_cache must invalidate the memory cache file. That is why sss_mc_set_recycled was copied to the tools_mc_util.c (as helper function for sss_memcache_invalidate function). It was duplicated to allow this function to remain static (and invisible to any .h files), so that it is not used anywhere else. Wrong usage of this function might cause race conditions and corrupt the cache. I'll add comments about the duplication to the code.

2013-04-08Allocate PAM DP request data on responder contextJakub Hrozek3-5/+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.

2013-04-02Making the authtok structure really opaque.Lukas Slebodnik2-14/+12
Definition of structure sss_auth_token was removed from header file authtok.h and there left only declaration of this structure. Therefore only way how to use this structure is to use accessory function from same header file. To creating new empty authotok can only be used newly created function sss_authtok_new(). TALLOC context was removed from copy and setter functions, because pointer to stuct sss_auth_token is used as a memory context. All declaration of struct sss_auth_token variables was replaced with pointer to this structure and related changes was made in source code. Function copy_pam_data can copy from argument src which was dynamically allocated with function create_pam_data() or zero initialized struct pam_data allocated on stack. https://fedorahosted.org/sssd/ticket/1830
2013-04-02Reusing create_pam_data() on the other places.Lukas Slebodnik1-1/+1
Function create_pam_data() should be only one way how to create new struct pam_data, because it also initialize destructor to created object.

2013-03-20change responder contexts hierarchyPavel Březina6-65/+94
https://fedorahosted.org/sssd/ticket/1575 The hierarchy is now: main_ctx -> responder_ctx -> specific_ctx where specific_ctx is one of sudo, pam, etc.

2013-03-19Move SELinux processing to provider.Michal Zidek1-309/+0
The SELinux processing was distributed between provider and pam responder which resulted in hard to maintain code. This patch moves the logic to provider. IT ALSO REQUIRES CHANGE IN THE SELINUX POLICY, because the provider also writes the content of selinux login file to disk (which was done by responder before). https://fedorahosted.org/sssd/ticket/1743
2013-03-19Removing unused declaration of functions and variable.Lukas Slebodnik1-1/+0
Variables dir_cc and file_cc are used in three modules: krb5_common.c, krb5_utils.c, krb5_child-test.c, therefore should be declared with extern in krb5_utils.h.
2013-03-08Move sss_cmd_execute from client to responder code.Jakub Hrozek3-7/+15
I think it logically belongs there and allows to better exercise the responder commands from unit tests.
2013-03-07Debug message in sss_mc_create_file.Michal Zidek1-0/+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.
2013-03-07File descriptor leak in nss responder.Michal Zidek1-18/+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

This parameter was never used. https://fedorahosted.org/sssd/ticket/1765
2013-03-04Use the same dbg level for all ncache hits.Michal Zidek2-21/+28
We used different debug levels for messages informing about negative cache hits (old levels 2,3,4). Now it is only SSSDBG_TRACE_FUNC (same level is used in nsssrv_services.c and proposed in the ticket bellow). https://fedorahosted.org/sssd/ticket/1771

2013-03-01autofs: fix invalid header 'number of entries' in packetPavel Březina1-1/+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.

2013-02-10Parent and subdomains use the same sysdbSimo Sorce2-71/+8
Remove code that tries to get the 'right' sysdb, as it is always going to get the same answer anyway since the recent patches to rework the domains/sysdb relationship.
2013-02-10Change the way domains are linked.Simo Sorce3-78/+32
- Use a double-linked list for domains and subdomains. - Never remove a subdomain, simply mark it as disabled if it becomes unused. - Rework the way subdomains are refreshed. Now sysdb_update_subdomains() actually updates the current subdomains and marks as disabled the ones not found in the sysdb or add new ones found. It never removes them. Removal of missing domains from sysdb is deferred to the providers, which will perform it at refresh time, for the ipa provider that is done by ipa_subdomains_write_mappings() now. sysdb_update_subdomains() is then used to update the memory hierarchy of the subdomains. - Removes sysdb_get_subdomains() - Removes copy_subdomain() - Add sysdb_subdomain_delete()
2013-02-10Add function get_next_domain()Simo Sorce11-101/+83
Use this function instead of explicitly calling domain->next This function allows to get the next primary domain or to descend into the subdomains and replaces also get_next_dom_or_subdom()

2013-01-22sudo responder: change num_rules type from size_t to uint32_tPavel Březina5-20/+20
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.
2013-01-16Invalidate user entry even if there are no groupsJakub Hrozek1-6/+1
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.
2013-01-16NSS: invalidate memcache user entry on initgr, tooJakub Hrozek1-0/+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.
