2011-04-29s3: In winbind, close parent/child socketsVolker Lendecke1-1/+1
This should further reduce fd load in winbind children
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.

2011-01-19s3: Add wbinfo --dc-infoVolker Lendecke1-0/+93
wbinfo --dc-info prints the current DC name and IP address. This helps diagnosing problems that might happen when a later wbinfo --ping-dc fails. This patch started out by using the SAF and NBT cache entires, but those are relatively short-lived. So I decided to invent a new gencache entry with a very long timeout. We need to go via the gencache because when for some reason a winbind child process is stuck, we can't query it for the current DC it's connected to. This must eventually go away again when we have a fully async winbind. Autobuild-User: Volker Lendecke <vlendec@samba.org> Autobuild-Date: Wed Jan 19 08:40:28 CET 2011 on sn-devel-104

2010-11-14Fix the unexpected.tdb database problem. Change nmbd to store theJeremy Allison1-1/+6
transaction id of packets it was requested to send via a client, and only store replies that match these ids. On the client side change clients to always attempt to ask nmbd first for name_query and node_status calls, and then fall back to doing socket calls if we can't talk to nmbd (either nmbd is not running, or we're not root and cannot open the messaging tdb's). Fix readers of unexpected.tdb to delete packets they've successfully read. This should fix a long standing problem of unexpected.tdb growing out of control in noisy NetBIOS envioronments with lots of bradcasts, yet still allow unprivileged client apps to work mostly as well as they already did (nmblookup for example) in an environment when nmbd isn't running.

2010-09-30s3: Add "smbcontrol winbindd ip-dropped <local-ip>"Volker Lendecke1-0/+33
This is supposed to improve the winbind reconnect time after an ip address has been moved away from a box. Any kind of HA scenario will benefit from this, because winbindd does not have to wait for the TCP timeout to kick in when a local IP address has been dropped and DC replies are not received anymore.
