2011-01-21s3:winbind: Fork multiple children per domainVolker Lendecke1-5/+45
This makes us scale better with many simultaneous winbind requests, some of which might be slow. This implementation breaks offline logons, as the cached credentials are maintained in a child (this needs fixing). So, if the offline logons are active, only allow one DC connection. Probably the offline logon and the scalable file server cases are separate enough so that this patch is useful even with the restriction.

2010-12-06s3: Fix bug 7844: Race in winbindVolker Lendecke1-4/+8
If a child dies, the parent process right away closes the socket. This is wrong, with tevent we still have events pending. This works fine for epoll but does not for at least the FreeBSD select variant. Tevent sticks a closed socket into the select masks. This then returns an error EBADF. When this happens, the parent winbind dies instead of forking a new child. This moves the socket close from the SIGCHLD cleanup function to the socket receiver. I could not reproduce the parent death anymore and it did not create an obvious fd leak. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Mon Dec 6 23:21:02 CET 2010 on sn-devel-104

2010-10-01s3:events: Call all ready fd event handlers on each iteration of the main loopSteven Danneman1-3/+3
Previously, only one fd handler was being called per main message loop in all smbd child processes. In the case where multiple fds are available for reading the fd corresponding to the event closest to the beginning of the event list would be run. Obviously this is arbitrary and could cause unfairness. Usually, the first event fd is the network socket, meaning heavy load of client requests can starve out other fd events such as oplock or notify upcalls from the kernel. In this patch, I have changed the behavior of run_events() to unset any fd that it has already called a handler function, as well as decrement the number of fds that were returned from select(). This allows the caller of run_events() to iterate it, until all available fds have been handled. I then changed the main loop in smbd child processes to iterate run_events(). This way, all available fds are handled on each wake of select, while still checking for timed or signalled events between each handler function call. I also added an explicit check for EINTR from select(), which previously was masked by the fact that run_events() would handle any signal event before the return code was checked. This required a signature change to run_events() but all other callers should have no change in their behavior. I also fixed a bug in run_events() where it could be called with a selrtn value of -1, doing unecessary looping through the fd_event list when no fds were available. Also, remove the temporary echo handler hack, as all fds should be treated fairly now.

2010-09-30s3: Add "smbcontrol winbindd ip-dropped <local-ip>"Volker Lendecke1-0/+22
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.

Giving the parent pid to reinit_after_fork is not a good idea.... None of the other callers do this, checked it.

2010-04-01s3:winbindd: fix problems with SIGCHLD handling (bug #7317)Stefan Metzmacher1-3/+3
The main problem is that we call CatchChild() within the parent winbindd, which overwrites the signal handler that was registered by winbindd_setup_sig_chld_handler(). That means winbindd_sig_chld_handler() and winbind_child_died() are never triggered when a winbindd domain child dies. As a result will get "broken pipe" for all requests to that domain. To reduce the risk of similar bugs in future we call CatchChild() in winbindd_reinit_after_fork() now. We also use a full winbindd_reinit_after_fork() in the cache validation child now instead instead of just resetting the SIGCHLD handler by hand. This will also fix possible tdb problems on systems without pread/pwrite and disabled mmap as we now correctly reopen the tdb handle for the child. metze

2009-11-19s3: Avoid races to change the machine password in winbindVolker Lendecke1-0/+18
The machine password handler has code to deal with every node in the cluster trying to change the machine password at the same time. However, it is not very nice to the DC if everyone tries this simultaneously. This adds a random 0-255 second offset to our timed event. When this fires a bit later than strictly calculated, someone else might have stepped in and have already changed it. The timed event handler will handle this gracefully, it won't even try to do it again.
2009-11-19s3: Protect against flooding the DC with pwchange requestsVolker Lendecke1-14/+24
When there is a temporary problem changing passwords we flooded the DC with pwchange requests. This gives the DC a 60-second break to recover.
