* smbd: Sort notify events by timestampVolker Lendecke2014-04-231-0/+16
| | | | | | | | | | | | | This will fix the raw.notify test with the new messaging system. With the new messaging system messages come in via yet another fd that has to line up in poll next to the incoming client TCP socket. With the signal-based messaging messages were always handled before client requests. The new scheme means that notify messages might be deferred a bit (something which can happen in a cluster already now), which then means that notify_marshall_changes() will coalesce entries, which in turn makes raw.notify unhappy.

* smbd: Add a timestamp to queued notify eventsVolker Lendecke2014-04-231-7/+14
| | | | | | | | | | | In a cluster and with changed messaging it can happen that messages are scheduled after new SMB requests. This re-ordering breaks a few notify tests. This starts the infrastructure to add timestamps to notify events, so that they can be sorted before they are sent out. The timestamp will be the current local time of notify_fname, that's all we can do. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Messaging based on unix domain datagram sockets This makes every process participating in messaging bind on a unix domain datagram socket, similar to the source4 based messaging. The details are a bit different though: Retry after EWOULDBLOCK is done with a blocking thread, not by polling. This was the only way I could in experiments avoid a thundering herd or high load under Linux in extreme overload situations like many thousands of processes sending to one blocked process. If there are better ideas to do this in a simple way, I'm more than happy to remove the pthreadpool dependency again. There is only one socket per process, not per task. I don't think that per-task sockets are really necessary, we can do filtering in user space. The message contains the destination server_id, which contains the destination task_id. I think we can rebase the source4 based imessaging on top of this, allowing multiple imessaging contexts on top of one messaging_context. I had planned to do this conversion before this goes in, but Jeremy convinced me that this has value in itself :-) Per socket we also create a fcntl-based lockfile to allow race-free cleanup of orphaned sockets. This lockfile contains the unique_id, which in the future will make the server_id.tdb obsolete. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>

* lib: Add unix_msgVolker Lendecke2014-04-237-0/+1358
| | | | | | | | | | | | | | | | | | This is a messaging layer based on unix domain datagram sockets. Sending to an idle socket is just one single nonblocking sendmsg call. If the recv queue is full, we start a background thread to do a blocking call. The source4 based imessaging uses a polling fallback. In a situation where thousands of senders beat one single blocked socket, this will generate load on the system due to the constant polling. This does not happen with a threaded blocking send call. The threaded approach has another advantage: We save become_root() calls on the retries. The access checks are done when the blocking socket is connected, the threaded blocking send call does not check permissions anymore.
