2009-06-30Eliminate segfault on first start-upStephen Gallagher1-6/+19
There was a typo in the confdb setup portion of the monitor_process_init that was attempting to use the wrong cdb object to initialize. This patch also adds some missing talloc_free() calls on error.
2009-06-19Protect against segfault in service_signal_reloadStephen Gallagher1-0/+9
There is a potential race condition where the monitor may attempt to signal a reload of a child process before the communication sbus channel is available. If this happens, we will just exit this function and let the monitor kill and restart the child process.
2009-06-19Fix segfault in update_monitor_configStephen Gallagher1-8/+26
We were stealing the memory context of only the first value in the linked-list of domains (and also services). This patch adds a memory context to hold the lists so that can be stolen along with all of the entries.
2009-05-28Make Data Provider a mandatory serviceJakub Hrozek1-0/+32
2009-05-26Stop overwriting the stackSimo Sorce1-2/+2
Actually use the buffer not it's location on the stack.
2009-05-26Read the config before startup, fail if cannot be readJakub Hrozek1-0/+26
2009-05-15Treat the local provider as a special caseStephen Gallagher1-1/+16
The local provider needs no backend, so we'll create a special provider entry for it called "local" that will not attempt to retrieve provider configuration but will remain in the service list so it can be updated when the config file changes.
2009-05-14Check for valid ID range, domains overlapJakub Hrozek1-0/+36
2009-05-12Fix warnings in monitor.c and confdb.cStephen Gallagher1-6/+12
2009-05-11Separate confdb API from confdb setupStephen Gallagher1-0/+1
Refactoring the confdb so that the setup code can be linked separately from the access API. This is being done so that our plugins do not need to link against the collection and ini_config libraries.
2009-05-08Use tevent for shutdown signals, remove old pidfile, make sssd single-instance.Jakub Hrozek1-0/+70
Use tevent signal handling facilities for handlong SIGTERM and SIGINT in the monitor. Remove pidfile on SIGTERM and SIGINT. Make sssd single-instance by checking if we suceeded in signaling the process in the pidfile.
2009-04-29Fix configuration corruption issueStephen Gallagher1-2/+20
In the event that the configuration was corrupt the first time the SSSD is started, it would write in the special data for attributes and indexes, but it would fail before writing the version. Subsequent reloads (even with correct configuration files) would fail, since they would try again to write the attributes and indexes and fail since they were already present.
2009-04-14Add common function to retrieve comma sep. listsSimo Sorce1-50/+4
Also convert all places where we were using custom code to parse config arguments. And fix a copy&paste error in nss_get_config
2009-04-14Make reconnection to the Data Provider a global settingStephen Gallagher1-1/+1
Previously, every DP client was allowed to set its own "retries" option. This option was ambiguous, and useless. All DP clients will now use a global option set in the services config called "reconnection_retries"
2009-04-13Fix a couple of segfaults and timeout checksSimo Sorce1-1/+3
2009-04-13Allow configuration of the SSSD through /etc/sssd/sssd.confStephen Gallagher2-13/+347
The SSSD now links with the ini_config and collection libraries in the common directory. The monitor will track changes to the /etc/sssd/sssd.conf file using inotify on platforms that support it, or polled every 5 seconds on platforms that do not. At startup or modification of the conf file, the monitor will purge the existing confdb and reread it completely from the conf file, to ensure that there are no lingering entries. It does this in a transaction, so there should be no race condition with the client services. A new option has been added to the startup options for the SSSD. It is now possible to specify an alternate config file with the -c <file> at the command line.
2009-04-10Redesign the the monitor's configuration to enable live reloadsStephen Gallagher2-150/+618
Fixes requested during code review
2009-04-09Make the monitor address a compile-time optionStephen Gallagher1-20/+10
Previously it was runtime-selectable in the confdb, but this is not a sensible approach, as if it were to change during runtime, it would cause problems communicating with the child services.
2009-04-08Change the way we retrieve domainsSimo Sorce1-11/+10
To be able to correctly filter out duplicate names when multiple non-fully qualified domains are in use we need to be able to specify the domains order. This is now accomplished by the configuration paramets 'domains' in the config/domains entry. 'domains' is a comma separated list of domain names. This paramter allows also to have disbaled domains in the configuration without requiring to completely delete them. The domains list is now kept in a linked list of sss_domain_info objects. The first domain is also the "default" domain.
2009-03-27Fix bug where services restarted by the monitor would be pinged more than ↵Stephen Gallagher1-0/+8
once per cycle
2009-03-20Enhance server_setupSimo Sorce1-3/+4
Now it can load from scratch default configuration that is valid for all daemons. First thing, make it possible for each daemon/provider to set its own debug level in its configuration entry.
2009-03-20Simplify default configurationSimo Sorce1-11/+65
Make confdb load a base ldif like sysdb to initialize the db, makes it simpler to understand at first sight what is the default configuration. Make the parameter "command" optional. Derive the default command from available information. Make the debug level a global by default so that enabling debug for all components is as easy as passing just -d X to the sssd binary.
2009-03-19Remove references to FreeIPA from D-BUS interfacesStephen Gallagher1-4/+4
Per discussion with the desktop team, using the org.freedesktop interface name will simplify adoption, as potential users won't feel like they're pulling in a FreeIPA dependency.
2009-03-07Fix race condition with initial sysdb creationStephen Gallagher1-0/+14
When the sysdb LDB file does not exist on the system, the first attempt to connect to it will invoke a creation routine. However, both the NSS and the InfoPipe are started in parallel by the monitor, resulting in a race condition as they both try to initialize the sysdb. The easiest fix for this is to simply have the monitor create the sysdb before it launches NSS and InfoPipe.
2009-03-06Implement CreateUser in InfoPipeStephen Gallagher1-1/+1
Changed the order of the arguments to CreateUser in the Introspection XML to match the other functions (domain belongs second on the list) A few other minor fixes as well: Fixed a typo in SYSDB_GETCACHED_FILTER and sysdb_transaction_end(). Added missing error handling in infp_do_user_set_uid().
2009-02-28Fix confdb issues.Simo Sorce1-2/+4
Avoid uninitialized memory messages in valgrind (in _btreemap_get_keys). Do not free memory we just stored in the btree (in confdb_get_domains_list). Streamline confdb_get_domains() and remove extra calls when we already have all the information handy. Do not store basedn in domain info, the base dn is always calculated out of the domain name. Remove the "provider" attribute, it was really used only to distinguish between LOCAL and other domains, directly check for LOCAL as a special case instead.
2009-02-27Refactor creation of domain_map into confdbStephen Gallagher1-2/+3
The NSS provider, the Data Provider backends and the InfoPipe all need access to the domain map provided by the confdb. Instead of reimplimenting it in multiple places, it is now provided in a pair of helper functions from the confdb. confdb_get_domains() returns a domain map by reference. Always returns the most up-to-date set of domains from the confdb. confdb_get_domains_list() returns an array of strings of all the domain names. Always returns the most up-to-date set of domains from the confdb. This patch also modifies the btreemap_get_keys() function to better handle memory and report allocation failures.
2009-02-26Rebase the code to use talloc, tdb, tevent, ldb as externalSimo Sorce2-20/+18
dependencies based on the latest samba code. Convert all references to the old events library to use the renamed tevent library.
2009-02-24Proper fix for memory handling problem.Simo Sorce1-10/+8
sbus_message_handler is not responsible anymore for sending back data in any case. Transfer this responsibility to the handler function called. This way both synchronous and asynchronous funstions use the interface the same way and can properly free memory referenced by the reply after the send buffer has been filled in and all copies are done in sbus_conn_send_reply()
2009-02-24Revert "Fixing serious memory allocation bug in sbus_message_handler."Simo Sorce1-3/+6
This reverts commit 13421cbe0af4343f9d110600755ffa756690b282. Conflicts: server/infopipe/infopipe.c server/infopipe/infopipe.h While this solution fixed the contingent memory problem it introduced other problems in handling asynchronous replies. Reverting in preparation for a different way to solve it. Conflicts have been taken care of.
2009-02-23Fixing serious memory allocation bug in sbus_message_handler.Stephen Gallagher1-6/+3
dbus_message_append_args() adds a reference to memory that is not copied to the outgoing message until dbus_connection_send() is called. Since we compile our reply messages in functions and then return the reply, we need a mechanism for deleting allocated memory after invoking dbus_connection_send. I have changed the arguments to sbus_msg_handler_fn so that it takes a talloc ctx containing the sbus_message_handler_ctx and a pointer to a reply object. We can now allocate memory as a child of the reply context and free it after calling dbus_connection_send.
