ec32b22ed5 r5037: got rid of all of the TALLOC_DEPRECATED stuff. My apologies for the
large commit. I thought this was worthwhile to get done for
consistency.

7f981b9ed9 r4944: every event_add_*() caller was having to call talloc_steal() to take
control of the event, so instead build that into the function. If you
pass NULL as mem_ctx then it leaves it as a child of the events
structure.

a3c7417cfe r4943: Smplified the events handling code a lot. The first source of
complexity was that events didn't automatically cleanup
themselves. This was because the events code was written before we had
talloc destructors, so you needed to call event_remove_XX() to clean
the event out of the event lists from every piece of code that used
events. I have now added automatic event destructors, which in turn
allowed me to simplify a lot of the calling code.

The 2nd source of complexity was caused by the ref_count, which was
needed to cope with event handlers destroying events while handling
them, which meant the linked lists became invalid, so the ref_count ws
used to mark events for later destruction.

The new system is much simpler. I now have a ev->destruction_count,
which is incremented in all event destructors. The event dispatch code
checks for changes to this and handles it.

d5fa02746c r4728: split up server_services into:
- stream_socket services
  the smb, ldap and rpc service which sets up a srtam socket end then
  waits for connections
and
- task services
  which this you can create a seperate task that do something
  (this is also going through the process_model subsystem
  so with -M standard a new process for this created
  with -M thread a new thread ...

I'll add datagram services later when we whave support for datagram sockets in lib/socket/

see the next commit as an example for service_task's

bfca9eb7cb r3631: a couple of tweaks to the talloc hierarchy for async requests in
pvfs. This prevents a possible crash due to free ordering on
unexpected disconnect.

e53ec2f6b6 r3595: - fixed a talloc_free ordering problem on cleanup with pending requests
- added initial support for MODE_INFORMATION in setfileinfo (I have no
  idea what "mode information" on a file is - it takes a value of 0,
  2, 4 or 6. What could it be?)

f23d6a2800 r3540: added testing of SMBntcancel in the open/open/close mux
testing. Interestingly, w2k3 does not allow the cancel of an
outstanding async open request, whereas it does allow the cancel of an
outstanding async lock request. To support this I have changed the
pvfs_wait interface to provide a enum on why the event is happening,
so the callback can decide what to do.

3423e2f414 r3528: added support for the SMBntcancel() operation, which cancels any
outstanding async operation (triggering an immediate timeout).

pvfs now passes the RAW-MUX test

0d51511d40 r3507: - added deferred replies on sharing violation in pvfs open. The
deferred reply is short-circuited immediately when the file is
  closed by another user, allowing it to be opened by the waiting user.

- added a sane set of timeval manipulation routines

- converted all the events code and code that uses it to use struct
  timeval instead of time_t, which allows for microsecond resolution
  instead of 1 second resolution. This was needed for doing the pvfs
  deferred open code, and is why the patch is so big.

fde64c0dc1 r3336: use a struct ntvfs_async_state to be able to do async chaning of ntvfs modules
the idea is that a passthru module can use ntvfs_async_state_push() before
calling ntvfs_next_*() and in the _send function it calls
ntvfs_async_state_pop() and then call the upper layer send_fn itself

- ntvfs_nbench is now fully async

- the ntvfs_map_*() functions and the trans(2) mapping functions are not converted yet

7f2c771b0e r3278: - rewrote the client side rpc connection code to use lib/socket/
rather than doing everything itself. This greatly simplifies the
  code, although I really don't like the socket_recv() interface (it
  always allocates memory for you, which means an extra memcpy in this
  code)

- fixed several bugs in the socket_ipv4.c code, in particular client
  side code used a non-blocking connect but didn't handle EINPROGRESS,
  so it had no chance of working. Also fixed the error codes, using
  map_nt_error_from_unix()

- cleaned up and expanded map_nt_error_from_unix()

- changed interpret_addr2() to not take a mem_ctx. It makes absolutely
  no sense to allocate a fixed size 4 byte structure like this. Dozens
  of places in the code were also using interpret_addr2() incorrectly
  (precisely because the allocation made no sense)

a256e71029 r3039: This solves the problem of async handlers in ntvfs backends not being
in the right state when called. For example, when we use the unixuid
handler in the chain of handlers, and a backend decides to continue a
call asynchronously then we need to ensure that the continuation
happens with the right security context.

The solution is to add a new ntvfs operation ntvfs_async_setup(),
which calls all the way down through the layers, setting up anything
that is required, and takes a private pointer. The backend wanting to
make a async calls can use ntvfs_async_setup() to ensure that the
modules above it are called when doing async processing.

5ef80f034d r3034: - fixed a bug in message dispatch, when the dispatch function called messaging_deregister()
- added a pvfs_lock_close_pending() hook to remove pending locks on file close

 - fixed the private ptr argument to messaging_deregister() in pvfs_wait

 - fixed a bug in continuing lock requests after a lock that is blocking a pending lock is removed

 - removed bogus brl_unlock() call in lock continue

 - corrected error code for LOCKING_ANDX_CHANGE_LOCKTYPE

 - expanded the lock cancel test suite to test lock cancel by unlock and by close

 - added a testsuite for LOCKING_ANDX_CHANGE_LOCKTYPE

4395c0557a r3029: implemented byte range lock timeouts.
This adds a pvfs_wait_message() routine which uses the new messaging
system, event timers and talloc destructors to give a nice generic
async event handling system with a easy to use interface. The
extensions to pvfs_lock.c are based on calls to pvfs_wait_message()
routines.

We now pass all of our smbtorture locking tests, although while
writing this code I have thought of some additonal tests that should
be added, particularly for lock cancel operations. I'll work on that
soon.

This commit also extends the smbtorture lock tests to test the rather
weird 0xEEFFFFFF locking semantics that I have discovered in
win2003. Win2003 treats the 0xEEFFFFFF boundary as special, and will
give different error codes on either side of it. Locks on both sides
are allowed, the only difference is which error code is given when a
lock is denied. Anyone like to hazard a guess as to why? It has
me stumped.
