2011-05-06Allow changing the log level without restartStephen Gallagher3-7/+28
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.
2011-05-06Create common sss_monitor_init()Stephen Gallagher2-0/+49
This was implemented almost identically for both the responders and the providers. It is easier to maintain as a single routine. This patch also adds the ability to provide a private context to attach to the sbus_connection for later use.
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
2011-01-17Remove support for pre-1.1 netlinkStephen Gallagher1-32/+0
Netlink 1.0 and older is buggy and unreliable, occasionally causing tight-loops. We're no longer going to try to support it. https://fedorahosted.org/sssd/ticket/755
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.

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.

2010-11-18Wait for all children to exitStephen Gallagher1-2/+61
Previously, there was a race-condition where the monitor might terminate before its children.

2010-11-05Handle errors during log reopening betterStephen Gallagher1-1/+2
2010-10-19Write log opening failures to the syslogStephen Gallagher1-1/+1
If there is a problem with reopening the logs, it can be an audit trail issue.
2010-09-08Dead assignments cleanup in various places in SSSDJan Zeleny1-0/+3
Three assignments deleted, two return code inspection added. Also found and fixed one critical bug caused by dead assignment. Ticket: #590
2010-07-09Use netlink to detect going onlineJakub Hrozek4-0/+453
Integrates libnl to detect adding routes. When a route is added, the offline status of all back ends is reset. This patch adds no heuristics to detect whether back end went offline. Fixes: #456
2010-07-09Add try_inotify optionStephen Gallagher1-1/+18
There are some special cases where inotify cannot be used, even if the host OS claims that it is supported. In these cases, it should be possible to explicitly disable the use of inotify. https://fedorahosted.org/sssd/ticket/484
2010-06-28Resend SIGINT as SIGTERM in servicesJakub Hrozek1-0/+1
Fixes: #462
2010-06-10Check the correct variable for NULL after creating timerStephen Gallagher1-2/+2
In several places, we were creating a new timer and assigning it to the tev variable, but then we were checking for NULL from the te variable (which, incidentally, is guaranteed never to be NULL in this situation) https://fedorahosted.org/sssd/ticket/523
2010-06-10Properly handle read() and write() throughout the SSSDStephen Gallagher1-2/+2
We need to guarantee at all times that reads and writes complete successfully. This means that they must be checked for returning EINTR and EAGAIN, and all writes must be wrapped in a loop to ensure that they do not truncate their output.

2010-04-26Fix a potential memory violationSumit Bose1-2/+4
If read() returns with errno set to EINTR -1 is added to total_len.
2010-04-12sysydb: Finally stop using a common event contextSimo Sorce1-1/+1
This commit completes the migration to a synchronous sysdb
2010-03-25Fix warnings from -Wmissing-field-initializersSumit Bose1-1/+1
This patch removes some tab-indentations from pamsrv.c, too.
2010-03-22Add generic error messageJakub Hrozek1-0/+4
2010-03-22Fix config file error messageJakub Hrozek1-1/+1
2010-03-19Fix multiple errors with destructors.Simo Sorce1-2/+22
This commits cleans up 3 segfaults/valgrind errors due to access to freed memory. 1. The spy wasn't clearing conn_spy causing the svc_destructor to try to clear the spy destructor when the spy was already freed 2. get_config_service was not setting the svc_destrcutor on services depending on the orderof frees at exit this was causing the spy destructor to try to access freed memory because it was not neutralized when the service was freed. 3. at exit the mt_ctx could be freed before services causing the svc_destrcutor to try to access freed memory when removing the service from the service list in the monitor context.

2010-03-17Fix a series of memory leaks in the SBUSStephen Gallagher2-9/+19
2010-03-15Properly handle dbus send attempts on a closed connectionStephen Gallagher2-67/+12
dbus_connection_send_with_reply() will report success and return a NULL pending_reply when the connection is not open for communication. This patch creates a new wrapper around dbus_connection_send_with_reply() to properly detect this condition and report it as an error.
2010-03-15Flush NSCD cache after modifying local databaseJakub Hrozek2-0/+14
Fixes: #221
2010-03-08Reopen logs when SIGHUP is caughtJakub Hrozek3-3/+26
Upon receiving SIGHUP, the monitor signals all services to reopen their debug logs. It is also possible to signal individual services to reopen their particular files. Fixes: #332
2010-03-04Add forgotten \n in DEBUG statementsMartin Nagy1-3/+3
Logs from confdb with missing '\n' in the DEBUG statements annoyed me so I decided to fix them. I also made a quick grep through the code and found other places so I fixed them too.
2010-03-04Eliminate monitor reconfigStephen Gallagher2-353/+4
We disabled live reconfiguration a long time ago with the intent of fixing it so that it wasn't completely broken, but we've decided that live updates are too delicate to handle all cases gracefully. For the forseeable future, we will rely on process restart for updating the configuration. Furthermore, we had not completely disabled live updates. It would still attempt to run if we sent a SIGHUP. This has also been eliminated.
