2011-05-04s3: Properly deal with exited winbind childrenVolker Lendecke1-0/+5
When a winbind child exits, we need to immediately close the socket. If not, the next request to that child will be sent to a socket without a listener, leading to a failed request. This failed request will then trigger a proper re-init. This patch avoids the one failed request.

2011-04-29s3: Avoid a potential 100% CPU loop in winbinddVolker Lendecke1-0/+27
In the clustering case if ctdb is unhappy, winbindd_reinit_after_fork fails. This can lead to an endless loop depending on the scheduling of the parent vs child. Parent forks, child is immediately scheduled and exits. Parent gets SIGCHLD, parent is then scheduled before it sends the request out to the child. Parent tries to fork again immediately. The code before this patch did not really take into account that reinit_after_fork can fail. The code now sends the result of winbindd_reinit_after_fork to the parent and the parent only considers the child alive when it got NT_STATUS_OK. This was seen in 3.4 winbind. winbind has changed significantly since then, so it might be possible that this does not happen anymore in exactly this way. But passing up the status of reinit_after_fork and only consider the child alive when that's ok is the correct thing to do anyway.

2011-04-28s3: Close the winbind client fds after forkingVolker Lendecke1-0/+10
In an overload situation, the winbind helper child process inherits all those hundreds of fd's which it will never talk to. Close them. We (Christian Ambach and me) just saw a crash in libkrb5. Christian's analysis showed that libkrb5 also does select, probably exceeding FD_SETSIZE and crashing due to that reason. The parent winbind in theory does not do Kerberos at all, so this should fix that problem. The crash is interesting because the child process did not really crash. Somewhere in glibc backtrace() is called, probably due to an assert() or some explicit consistency check. This then somehow generates a signal probably due to corrupted memory structures. That signal triggers Samba to again call backtrace(). This blocks hard on a ptrace_once(). Sorry for the long backtrace here, but this *is* interesting. The child process blocking and not really crashing makes the situation worse: The parent process does not get told the child has crashed and more client sockets pile up. This patch is intended to put some relief on this problem by closing the majority of sockets the parent holds.

2011-04-28s3-libads: Use ldap_init_fd() to connect to AD server in socket_wrapperAndrew Bartlett1-3/+3
This means that we control the connection setup, don't rely on signals for timeouts and the connection uses socket_wrapper where that is required in our test environment. According to bug reports, this method is also used by curl and other tools, so we are not the first to (ab)use the OpenLDAP libs in this way. It is ONLY enabled for socket_wrapper at this time, as this is the best way to get 'make test' working for S3 winbind tests in an S4 domain. Andrew Bartlett

2011-04-27s3-winbind Use get_dyn_WINBINDD_SOCKET_DIR() to get the winbind pipe dirAndrew Bartlett1-1/+1
This ensures we follow the dynconfig convention for the socket directory, and makes it easier to ensure that the client and server both refer to the same socket. Andrew Bartlett

Most fault codes have a NTSTATUS representation, so use that. This brings the fault handling in common with the source4/librpc/rpc code, which make it possible to share more highlevel code, between source3 and source4 as the error checking can be the same now. metze Autobuild-User: Stefan Metzmacher <metze@samba.org> Autobuild-Date: Sun Apr 24 10:44:53 CEST 2011 on sn-devel-104
