2012-10-05do not create pid file twicePavel Březina1-1/+6
If a provider is terminated and the monitor tries to restart it, it goes again through mark_service_as_started() which will try to create pid file again because number of running services didn't change. Because the pid file cannot be created twice, it will not return EOK and the whole SSSD is terminated.
2012-10-04Check for existing pidfile before starting the providersJakub Hrozek1-17/+15
After we switched to writing pidfile after the responders started, we forgot that starting a second SSSD instance would first overwrite the pipes and sockets and only then the SSSD would find out there already is a pidfile. This patch checks for existing pidfile before proceeding with startup.

2012-08-07monitor: set debug level when unable to load configurationPavel Březina1-0/+6
https://fedorahosted.org/sssd/ticket/1345 When the monitor is unable to load configuration and non debug level is set (e.g. when sssd is started via 'service'), none message was saved into logs. This patch forces debug messages to be written in this scenario.

This adds only the basic outline of the PAC responder, it won't support any operations, it will just start and initialize itself.

2011-11-22Set more strict permissions on keyringSimo Sorce1-0/+27
We want to confine access to the keyring to the current process and not let root easily peek into the keyring contents.

2011-09-28Multiline macro cleanupJakub Hrozek1-1/+2
This is mostly a cosmetic patch. The purpose of wrapping a multi-line macro in a do { } while(0) is to make the macro usable as a regular statement, not a compound statement. When the while(0) is terminated with a semicolon, the do { } while(0); block becomes a compound statement again.
2011-09-15MONITOR: Correctly detect lack of response from servicesStephen Gallagher1-21/+26
We were incorrectly using DBUS_ERROR_TIMEOUT here. The correct behaviour is to check for DBUS_ERROR_NO_REPLY. This way we will properly handle the three-tries in the tasks_check_handler(). Additionally, we weren't properly handling failure counts correctly, meaning we weren't restarting stuck services in a timely manner.
2011-09-08DEBUG timestamps offer higher precisionPavel Březina1-2/+26
https://fedorahosted.org/sssd/ticket/956 Added: --debug-microseconds=0/1 Added: debug_microseconds to sssd.conf
2011-09-06Change libnl monitor callback to only signal going onlineJakub Hrozek1-5/+3
This feature was not used and would probably never be used, because it is much safer to rely on online actions to time out. Moreover, it would make implementing the new features more complex.
2011-09-02Add option to specify the kerberos replay cache dirStephen Gallagher1-0/+31
Adds a configure option to set the distribution default as well as an sssd.conf option to override it. https://fedorahosted.org/sssd/ticket/980
2011-08-25--debug-timestamps=1 is not passed to providersPavel Březina1-44/+69
https://fedorahosted.org/sssd/ticket/972 --debug-timestamps=1 is now passed to providers
2011-08-25New DEBUG facility - SSSDBG_UNRESOLVED changed from -1 to 0Pavel Březina1-3/+7
Removed: SSS_UNRESOLVED_DEBUG_LEVEL (completely replaced with SSSDBG_UNRESOLVED) Added new macro: CONVERT_AND_SET_DEBUG_LEVEL(new_value) Changes unresolved debug level value (SSSDBG_UNRESOLVED) from -1 to 0 so DEBUG macro could be reduced by one condition. Anyway, it has a minor effect, every time you want to load debug_level from command line parameters, you have to use following pattern: /* Set debug level to invalid value so we can deside if -d 0 was used. */ debug_level = SSSDBG_INVALID; pc = poptGetContext(argv[0], argc, argv, long_options, 0); while((opt = poptGetNextOpt(pc)) != -1) { ... } CONVERT_AND_SET_DEBUG_LEVEL(debug_level);
2011-08-25New DEBUG facility - conversionPavel Březina1-2/+3
https://fedorahosted.org/sssd/ticket/925 Conversion of the old debug_level format to the new one. (only where it was necessary) Removed: SSS_DEFAULT_DEBUG_LEVEL (completely replaced with SSSDBG_DEFAULT)

2011-05-23Import config.h earlierStephen Gallagher1-2/+1
On RHEL 5 and other older platforms, failing to set _GNU_SOURCE early would cause some functions - such as strndup() - to be unavailable.

2011-05-16Fixed --debug-to-files for nss and pam servicesJan Zeleny1-4/+4
This error caused that monitor didn't pass --debug-to-files option to nss and pam services when creating them.
2011-05-06Allow changing the log level without restartStephen Gallagher1-1/+3
We will now re-read the confdb debug_level value when processing the monitor_common_logrotate() function, which occurs when the monitor receives a SIGHUP.
2011-05-04Override config file debug_level with command-lineStephen Gallagher1-13/+50
This patch also makes the following changes: 1) The [sssd] debug_level setting no longer acts as a default for all other sections. 2) We will now skip passing the debug argument to the child processes from the master unless the SSSD was run with a command-line argument for the debug level. https://fedorahosted.org/sssd/ticket/764
2011-01-17Clarify nscd warningStephen Gallagher1-4/+5
Removes the level-zero DEBUG message and modifies the syslog message to explain that NSCD is safe for maps that SSSD does not (yet) support.

https://fedorahosted.org/sssd/ticket/724
2010-12-02Set up signal handlers before initializing sysdbStephen Gallagher1-38/+38
A temporary signal handler for SIGTERM is set up in server_setup() that calls exit() from within a pure signal handler. This causes a race condition where it's possible that if the SSSD is restarted immediately while it is still initializing the sysdb caches for the first time, it can leave the cache in a corrupt and unusable state. https://bugzilla.redhat.com/show_bug.cgi?id=658444
2010-12-02Resend SIGTERM if child doesn't terminateStephen Gallagher1-24/+40
There is a race condition where if we send a SIGTERM before the kernel has scheduled the child, it may be lost, and the child will not terminate and will leave the monitor hung in wait(). This patch alters this behavior so that we will send the SIGTERM again every 10ms and check the wait() in a nonblocking manner.
