2013-01-15Refactor sysdb initializationSimo Sorce2-2/+1
Change the way sysdbs are initialized. Make callers responsible for providing the list of domains. Remove the returned array of sysdb contexts, it was used only by sss_cache and not really necessary there either as that tool can easily iterate the domains. Make sysdb ctx children of their respective domains. Neither sysdb context nor domains are ever freed until a program is done so there shouldn't be any memory hierarchy issue. As plus we simplify the code by removing a destructor and a setter function.
2013-01-08Update domain ID for local domain as wellSumit Bose1-2/+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.
2013-01-02failover: Protect against empty host namesMichal Zidek1-1/+2
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
2012-12-18responder_dp: Add timeout to side requetsSimo Sorce1-1/+25
This is an additional proteciont in case the provider misbheaves to avoid having requests pending forever. Fixes: https://fedorahosted.org/sssd/ticket/1717
2012-12-18RESPONDERS: Create a common file with service names and versionsJakub Hrozek1-0/+43
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/
2012-12-05Always append rctx as private dataSimo Sorce1-1/+1
This is used for the new calls back from the data provider.
2012-12-04NSS: Fix netgroup midpoint cache refreshJakub Hrozek1-1/+1
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.
2012-11-19Display more information on DB version mismatchOndrej Kos1-0/+1
https://fedorahosted.org/sssd/ticket/1589 Added check for determining, whether database version is higher or lower than expected. To distinguish it from other errors it uses following retun values (further used for appropriate error message): EMEDIUMTYPE for lower version than expected EUCLEAN for higher version than expected When SSSD or one of it's tools fails on DB version mismatch, new error message is showed suggesting how to proceed.
2012-11-08sss_dp_get_domains_send(): handle subreq error correctlyPavel Březina1-1/+2
If force is true, ret may stay uninitialized and if ret == 0 after the subrequest is send, we will go to immediate label. Data provider request is sent, but the answer is never processed. This prohibited subdomain from working correctly.
2012-10-29Free the internal DP requestJakub Hrozek1-0/+8
2012-10-12Save time of last get_domains requestSumit Bose1-0/+16
2012-10-11Fix memory hierarchy in subdomains discoveryJakub Hrozek1-116/+160
https://fedorahosted.org/sssd/ticket/1571 The patch changes the subdomains discovery to use the tevent_req style. Previously, the code violated several rules which made the code very unreadable and led to memory hierarchy issues and use-after-free errors.
2012-10-11do not call dp callbacks when responder is shutting downPavel Březina3-0/+25
https://fedorahosted.org/sssd/ticket/1514 We were experiencing crash duting responder shut down. This happened when there were some unresolved dp request during the shut down. The memory hierarchy is main_ctx->specific_ctx->rctx, where specific_ctx may be one of the pam, nss, sudo, etc. contexts. If we try to call dp request callback as a result of responder termination, the specific context is already semi freed, which may cause crash.

2012-08-15Fix LOCAL domain lookupsPavel Březina1-19/+22
https://fedorahosted.org/sssd/ticket/1436 Now subdomains are not evaluated for local domains.
2012-08-01Change subdomain_infoSimo Sorce1-1/+1
Rename the structure to use a standard name prefix so it is properly name-spaced, in preparation for changing the structure itself.
2012-07-10Fix segfault when using local providerStephen Gallagher1-6/+5
The name context was not being initialized for local provider domains because it was handled after skipping over the back-end initialization routine. This patch moves the name context init routine to occur earlier. https://fedorahosted.org/sssd/ticket/1412
2012-07-10pac responder: limit access by checking UIDsSumit Bose2-4/+142
A check for allowed UIDs is added in the common responder code directly after accept(). If the platform does not support reading the UID of the peer but allowed UIDs are configured, access is denied. Currently only the PAC responder sets the allowed UIDs for a socket. The default is that only root is allowed to access the socket of the PAC responder. Fixes: https://fedorahosted.org/sssd/ticket/1382
2012-06-20Move some debug lines to new debug log levelsStef Walter1-1/+1
* These are common lines of debug output when starting up sssd https://bugzilla.redhat.com/show_bug.cgi?id=811113

2012-06-12Make re_expression and full_name_format per domain optionsStef Walter4-17/+19
* Allows different user/domain qualified names for different domains. For example Domain\User or user@domain. * The global re_expression and full_name_format options remain as defaults for the domains. * Subdomains get the re_expression and full_name_format of their parent domain. https://bugzilla.redhat.com/show_bug.cgi?id=811663
2012-05-03SSH: Add dp_get_host_send to common responder codeJakub Hrozek2-13/+2
Instead of using account_info request, creates a new ssh specific request. This improves code readability and will make the code more flexible in the future. https://fedorahosted.org/sssd/ticket/1176
2012-05-02RESPONDER: check return value from confdb_get_intJakub Hrozek1-0/+7
sss_process_init forgot to check return value of confdb_get_int

2012-03-16Free entry found in negative cacheJakub Hrozek1-0/+3
2012-03-08Use the correct hash table for pending requestsSimo Sorce3-6/+10
The function that handled pending requests on reconnect was checking an orphaned global variable that was never used, redenring the whole function uselsess. This fixes a very nasty bug that was causing requests for which we never received an answer for (for example because the backend failed and was restarted) to be never removed and therefore causing a black hole effect for any other request of the same type. Fixes: https://fedorahosted.org/sssd/ticket/1229
2012-02-17RESPONDERS: Make the fd_limit setting configurableStephen Gallagher1-1/+18
This code will now attempt first to see if it has privilege to set the value as specified, and if not it will fall back to the previous behavior. So on systems with the CAP_SYS_RESOURCE capability granted to SSSD, it will be able to ignore the limits.conf hard limit. https://fedorahosted.org/sssd/ticket/1197
2012-02-17RESPONDERS: Allow increasing the file-descriptor limitStephen Gallagher2-0/+39
This patch will increase the file descriptor limit to 8k or the limits.conf maximum, whichever is lesser. https://fedorahosted.org/sssd/ticket/1197

2012-02-07DP: Add support for hosts in sss_dp_get_accountJan Cholasta2-2/+13
Host requests are directed to the host info handler.

2012-02-05RESPONDERS: Refactor setent_req_listJakub Hrozek2-5/+90
Makes the setent_add_ref() and setent_notify_*() functions more generic to be reusable by the autofs responder.
2012-02-02RESPONDERS: Provide a common sss_cmd_send_error functionJakub Hrozek2-0/+18
The common function could be reused in new responders
2012-01-31Refactor nss_cmd_send_emptyJakub Hrozek2-0/+39
2012-01-27NSS: Add service enumeration support to NSS providerStephen Gallagher1-0/+3
2012-01-27DP: Refactor responder_dp_req so it's reusable by other respondersJakub Hrozek2-239/+347
* the internal request is now more generic and is decoupled from account-specific data. There is a new sss_dp_issue_request() wrapper that issues a BE request or registers a callback * the public requests all use struct sss_dp_req_state as the tevent_req state data. This allows to report back data from the internal request even if the caller is just a callback notifier * each specific request now uses an _info structure that contains all the data necessary to construct a DBusMessage passed to provider * each specific request now defines a sss_dp_get_$data_msg callback that is called from the sss_dp_issue_request() common wraper. The purpose of the wrapper is to construct a DBusMessage and bind it to a DBus method so the message can be just sent over to back end The miscellanous changes include: * change SSS_DP_ constants to an enum. This way, a switch() would error if a value is not handled. * rename sss_dp_get_account_int_send() to sss_dp_internal_get_send() request because the internal request is going to handle more than just account data * the DBus return values were renamed from err_maj, err_min to dp_err and dp_ret respectively
2012-01-27NSS: Add negative cache routines for servicesStephen Gallagher2-3/+132
2012-01-27DP: Add support for services in dp requestsStephen Gallagher2-0/+4
2012-01-23DP: Fix bugs in sss_dp_get_account_intStephen Gallagher1-66/+44
The conversion to the tevent_req style introduced numerous bugs related to memory management of the various client requests. In some circumstances, this could cause memory corruption and segmentation faults in the NSS responder. This patch makes the following changes: 1) Rename the internal lookup from subreq to sidereq, to indicate that it is not a sub-request of the current lookup (and therefore is not cancelled if the current request is). 2) Change the handling of the callback loops since they call tevent_req_[done|error], which results in them being freed (and therefore removed from the cb_list. This was the source of the memory corruption that would occasionally result in dereferencing an unreadable request. 3) Remove the unnecessary sss_dp_get_account_int_recv() function and change sss_dp_get_account_done() so that it only frees the sidereq. All of the waiting processes have already been signaled with the final results from sss_dp_get_account_int_done()
