2009-05-27s3: Allow child processes to exit gracefully if we are out of fdsMarc VanHeyningen1-2/+3
When we run out of file descriptors for some reason, every new connection forks a child that immediately panics causing smbd to coredump. This seems unnecessarily harsh; with this code change we now catch that error and merely log a message about it and exit without the core dump. Signed-off-by: Tim Prouty <tprouty@samba.org>

2009-02-01Add two new parameters to control how we verify kerberos tickets. Removes ↵Dan Sledz1-1/+1
lp_use_kerberos_keytab parameter. The first is "kerberos method" and replaces the "use kerberos keytab" with an enum. Valid options are: secrets only - use only the secrets for ticket verification (default) system keytab - use only the system keytab for ticket verification dedicated keytab - use a dedicated keytab for ticket verification. secrets and keytab - use the secrets.tdb first, then the system keytab For existing installs: "use kerberos keytab = yes" corresponds to secrets and keytab "use kerberos keytab = no" corresponds to secrets only The major difference between "system keytab" and "dedicated keytab" is that the latter method relies on kerberos to find the correct keytab entry instead of filtering based on expected principals. The second parameter is "dedicated keytab file", which is the keytab to use when in "dedicated keytab" mode. This keytab is only used in ads_verify_ticket.

"rescan_trusted_domain". From analysis by hargagan <shargagan@novell.com> : "The winbindd_child_died() is also getting called from process_loop() in case of SIGCHLD signal. In this case it doesn't make the timeout_handler to NULL for the first request. It then initiate a new request using schedule_async_request() which installs a new timeout handler for the same request. In such a case, for a badly unresponsive system both the timeout handler can be called. For the first call the "private_data" will be cleared and for another call the timeout handler will be detecting the double free. So, for such a case as well, the winbindd_child_died() should make the timeout_handler to NULL." Jeremy.

2008-07-25Fix a race condition in winbind leading to a crashVolker Lendecke1-4/+3
When SIGCHLD handling is delayed for some reason, sending a request to a child can fail early because the child has died already. In this case async_main_request_sent() directly called the continuation function without properly removing the malfunctioning child process and the requests in the queue. The next request would then crash in the DLIST_ADD_END() in async_request() because the request pending for the child had been talloc_free()'ed and yet still was referenced in the list. This one is *old*... Volker (cherry picked from commit 8691709626b0d461de91b8fc9d10c730d1f183dd) (This used to be commit c70e2b6476d2d99c79624e15a4a3cfcdc850fc7c)

2008-07-01MSG_DEBUG now forwarded to all the winbindd children by parent.Darshan Purandare1-0/+34
smbcontrol winbindd debug level would only set the debug level of the parent winbindd process and not the child processes. This patch adds the functionality of broadcasting the debug message to all winbindd children. Now the debug level message is propagated to all the winbindd processes that includes parent and children. (This used to be commit cfbcfc3ffe74f28ec874a6bf1ab93f55f405b6e6)

2008-05-14Fix bug #5464. Pointed out by Herb @ Connectathon. In fork_domain_child() we ↵Jeremy Allison1-3/+3
call : CatchChild(); *before* we fork the domain child. This call establishes a signal handler that eats SIGCLD signals and doesn't call sys_select_signal() as the main daemon SIGCLD handler should do. This causes the parent to ignore dead children and time out, instead of calling winbind_child_died() on receipt of the signal. The correct fix is to move the CatchChild call into the child code after the fork. Jeremy. (This used to be commit 8d701a142be2b75dc30ad215bc178af902eb4af9)

2008-04-30Winbind: Prevent cycle in children list when reaping dead child processes.Gerald W. Carter1-0/+4
Thanks to Glenn Curtis and Kyle Stemen @ Likewise. Their explanation is: In winbindd_dual.c, there is a list of children processes that is maintained using macros DTLIST_ADD and DTLIST_REMOVE. In the case when a scheduled_async_request fails, the particular child was located in the list, and its attributes were cleared out and it was reused for a subsequent async request. The bug was that the new request would queue the same node into the doubly-linked list and would result in list->next pointing to the same node as list itself. This would set up an infinite loop in the processing of the for loop when the list of children was referenced. Solution was to fully remove the child node from the list, such that it could be inserted without risk of being inserted twice. Note that the child is re-added to the list in fork_domain_child() again. (This used to be commit b379b5b5d8a6daccc69aaf2be6d9a6e276e7dd78)
2008-04-23Fix CLEAR_IF_FIRST handling of messages.tdbVolker Lendecke1-1/+1
We now open messages.tdb even before we do the become_daemon. become_daemon() involves a fork and an immediate exit of the parent, thus the parent_is_longlived argument must be set to false in this case. The parent is not really long lived :-) (This used to be commit 4f4781c6d17fe2db34dd5945fec52a7685448aec)
