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.
