2013-05-03Add SID related calls to the NSS responderSumit Bose2-3/+795
The patch adds 4 new calls to the NSS responder: - SSS_NSS_GETSIDBYNAME - SSS_NSS_GETSIDBYID - SSS_NSS_GETNAMEBYSID - SSS_NSS_GETIDBYSID to either return the SIDs of the requested object or map the SID to the name or the POSIX ID of the related object.
2013-05-02Add idmap context to nss contextSumit Bose2-0/+22
This allows the nss responder to use libsss_idmap to convert between different SID representations.
2013-05-02Remove unused TALLOC_CTX from responder_get_domain()Sumit Bose3-4/+4
Recent refactoring removed the need to copy the domain info data of sub-domains because the related objects will not be removed from memory anymore.
2013-04-26DB: Switch to new libini_config APIOndrej Kos2-2/+1
https://fedorahosted.org/sssd/ticket/1786 Since we need to support the old interface as well, the configure scritp is modified and correct ini interface is chosen.
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.
2013-04-17Inform 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.

2013-03-20change responder contexts hierarchyPavel Březina1-15/+20
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.
2013-03-20do not leak memory on failure in *_process_init()Pavel Březina1-7/+12
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.
2013-03-07Debug 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
2013-03-04Use the same dbg level for all ncache hits.Michal Zidek1-18/+25
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

Fixes https://fedorahosted.org/sssd/ticket/1766
2013-02-10Add function get_next_domain()Simo Sorce3-75/+55
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()

2013-01-16Invalidate 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.
2013-01-15Add domain arguments to sysdb services functionsSimo Sorce1-6/+6
also fix sysdb_svc_add declarations
2013-01-15Add domain argument to sysdb_initgroups()Simo Sorce1-2/+2
2013-01-15Add domain option to sysdb_get/netgr/attrs() fnsSimo Sorce1-1/+1
2013-01-15Pass domain to sysdb_enum<pw/gr>ebt() functionsSimo Sorce1-4/+4
2013-01-15Pass domain to sysdb_get<pwu/grg><id() functionsSimo Sorce1-2/+2
2013-01-15Pass domain to sysdb_get<pw/gr>nam() functionsSimo Sorce1-9/+5
Also allows us to remove sysdb_subdom_get<pw/gr>nam() wrappers and restore fqnames proper value in subdomains, by testing for a parent domain being present or not.
2013-01-07memcache: add macro that validates record lengthPavel Březina1-2/+1
2013-01-07sss_userdel and sss_groupdel with use_fully_qualified_namesMichal Zidek1-15/+50
If use_fully_qualified_names is used, we need to pass fqdn to sss_mmap_cache_*_invalidate.
2012-12-20mmap cache: invalidate cache on fatal errorSimo Sorce3-10/+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.
2012-12-20Carefully check records when forcibly invalidatingSimo Sorce1-18/+101
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.
2012-12-20Update free table when records are invalidated.Simo Sorce1-14/+23
We were holding up slots when entries were invalidated directly an not through our primitive garbage collection scheme.
2012-12-20nss_mc: Add extra checks when dereferencing recordsSimo Sorce1-0/+12
Although it should enver happen that we pass in an invalid hash it is always better to just not do anything than access memory ouf of the hash table. It can lead to segfaults, or worse referencing memory that should not be touched.
2012-12-19sssd_nss: Plug memory leaksSimo Sorce1-2/+11
A recent patch introduced a glaring memory leak in the routines that clean up memcache memory on initgroups calls.
2012-12-18RESPONDERS: Create a common file with service names and versionsJakub Hrozek2-3/+1
The monitor sends calls different sbus methods to different responders. Instead of including headers of the particular responders directly in monitor, which breaks layering a little, create a common header file that will be included from src/responder/common/
2012-12-14Allow mmap calls to gracefully return absent ctxSimo Sorce1-0/+25
This is to allow to freely call mc functions even if initialization failed. They will now gracefully fail instead of segfaulting.
2012-12-13sssd_nss: Remove entries from memory cache if not found in sysdbMichal Zidek1-0/+23
Functions nss_cmd_getXXnam remove entries from memory cache if not found in sysdb cache of a local domain.
2012-12-11NSS: Fix the error handler in sss_mc_create_fileJakub Hrozek1-10/+16
https://fedorahosted.org/sssd/ticket/1704 The function is short enough so that we can simply stick with return and release resources before returning as appropriate.
2012-12-05Hook for mmap cache update on initgroup callsSimo Sorce3-0/+147
This set of functions enumerate the user's groups and invalidate them all if the list does not matches what we get from the caller.
2012-12-05Hook to perform a mmap cache update from sssd_nssSimo Sorce3-0/+118
This set of functions enumerate each user/group from all domains and invalidate any mmap cache record that matches.
2012-12-05mmap cache: public functions to invalidate recordsSimo Sorce2-0/+135
These functions can be called from the nss responder to invalidate records that have ceased to exist or that need to be refreshed the first time an application needs them.
2012-12-04NSS: Fix netgroup midpoint cache refreshJakub Hrozek2-2/+2
https://fedorahosted.org/sssd/ticket/1683 The result of the percent calculation was always 0 as it used plain ints. The patch switches to using explicit floats to avoid reintroducing the bug again even with brackets.
2012-11-19Refactor the way subdomain accounts are savedSimo Sorce1-3/+7
The original sysdb code had a strong assumption that only users from one domain are saved in the databse, with the subdomain feature, we have changed reality, but have not adjusted all the code arund the sysdb calls to not rely on the original assumption. One of the side effects of this incongrunece is that currently group memberships do not return fully qualified names for subdomain users as they should. In oreder to fix this and other potential issues surrounding the violation of the original assumption, we need to fully qualify subdomain user names. By savin them fully qualified we do not risk aliasing local users and have group memberhips or other name based matching code mistake a domain user with subdomain usr or vice versa.

2012-10-23Fix two errors in the nss responderSumit Bose1-1/+3
One is a copy-and-paste error which was introduce by 1774ee9a61b9d691dadd1a0538f32bcdcc84f72f. The second fixes a missing explicit setting of the return value. In the case where we want fully qualified names ret contains the number of characters from the last snprintf() which is almost ever not 0.
