This allows libauth not to depend on smbd_base. Andrew Bartlett

Using the standard macro makes it easier to move code into common, as TALLOC_ZERO_P isn't standard talloc.

2011-05-31s3: Mark sockets in error state writableVolker Lendecke1-0/+23
Without this patch, when a socket only has a write event pending, we will never detect an error condition. I've seen winbind doing 12:19:13.659964 gettimeofday({1306837153, 659984}, NULL) = 0 <0.000016> 12:19:13.660109 poll([{fd=35, events=POLLOUT}, {fd=32, events=POLLIN|POLLHUP}], 2, 9996) = 1 ([{fd=35, revents=POLLERR|POLLHUP}]) <0.000015> 12:19:13.660253 gettimeofday({1306837153, 660269}, NULL) = 0 <0.000013> 12:19:13.660298 poll([{fd=35, events=POLLOUT}, {fd=32, events=POLLIN|POLLHUP}], 2, 9996) = 1 ([{fd=35, revents=POLLERR|POLLHUP}]) <0.000015> for a while when trying to connect to a DC when the socket had died already.

2011-05-10s3-events: tevent_internal.h is not a public headerAndrew Tridgell1-1/+1
We need to use the "foo.h" form instead of the <foo.h> form for headers that are not installed publicly. Otherwise when an external version of tevent is used we won't find the header and the build will fail. Note that this creates a structure dependency between the tevent structures in the external library and the headers in our source tree. That is not ideal, but is currently OK as the waf build will only use the external library if it is at least the same version as the internal tree, which means it will actually be the same version, as we release the external version from our tree. We should come up with a better solution, but for now this allows openchange to build again.

2011-04-11s3: Fix timeout calculation in event_add_to_poll_argsVolker Lendecke1-1/+1
In the initial phase nmbd does not yet have timed events. This led to nmbd not correctly registering its names in make test and certainly everywhere else. Autobuild-User: Volker Lendecke <vlendec@samba.org> Autobuild-Date: Mon Apr 11 14:35:45 CEST 2011 on sn-devel-104

2011-01-23s3: Fix an infinite loopVolker Lendecke1-0/+4
If select returns EBADF (which should NEVER happen), then we loop infinitely because the select masks seem all active. I've been given an strace where smbd floods syslog with inotify-related error messages. The strace shows that select returns EBADF, and we're calling the inotify event callback. It then complains there's no data on the inotify fd. Metze, please check! We might need to fix this in 3.4 and 3.5 as well. And we need to find the deeper reason where we close a file descriptor and don't tell the events system about it.

2010-10-01s3:events: Call all ready fd event handlers on each iteration of the main loopSteven Danneman1-7/+15
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.

2010-02-05s3-events: make the old timed events compatible with teventAndrew Tridgell1-2/+19
tevent ensures that a timed event is only called once. The old events code relied on the called handler removing the event itself. If the handler removed the event after calling a function which invoked the event loop then the timed event could loop forever. This change makes the two timed event systems more compatible, by allowing the handler to free the te if it wants to, but ensuring it is off the linked list of events before the handler is called, and ensuring it is freed even if the handler doesn't free it.

2009-01-28Avoid valgrind errorsVolker Lendecke1-35/+13
In event handlers, we might destroy other events that are pending in the lists. We can only run one event safely per select call. Yes, I've seen these valgrind errors :-) Jeremy, with ccdd921e61 you had checked in the change to run multiple events. Do you remember why it was necessary and could not be solved in a different way?

2008-04-14Enable multiple fd events on a single file descriptorVolker Lendecke1-1/+1
Now we can have multiple events listen on a single fd. The order in which they are called is naturally not defined, meaning that it is only deterministic if exactly one event is readable or writeable. (This used to be commit 61503f822b60f98dd1f7549707ec89b48e32caeb)
