b61f89826f Fix for interesting resource constraint condition. When all opens are
level 2 and a request for open with no oplock is received then the
smbd should send *synchronous* break messages, not asynchronous,
otherwise it spins very rapidly, releasing the lock, sending the
'break to none' messages and then re-acquiring the lock before
any other process has a chance to get the lock and remove it's own
oplock (at least on linux).

9cd0306baa This split the mangling code up to allow for the possibility of multiple
mangling implementation, selectable using "mangling method = " in smb.conf

It also tidies the interface a little, although it is still nasty.

e6a6dee027 This is Jeremy pretending to be Volker, 'cos the
link from Seattle is having problems.
I've added 3 things here to work on the fcntl spin
problem.
1). Check *all* tdb return codes... :-).
2). If we're asking ourselves to break an oplock, and we can't
find a fsp pointer that matches the entry, this is a *logic bug*
and we should abort and panic so someone with gdb can pick up
the pieces.
3). After we've broken an oplock, ensure that the entry itself
has been removed, and if not remove it ourselves. This should
not be neccessary in a correctly working environmen,t, but will
provide an added layer of robustness in error situations.
4). I hate german keyboards :-) :-).

6f58dd5871 Ok - fixed a bug in our levelII oplock code. We need to break a level II on
a byte range lock (write lock only, but Win2k breaks on read lock also so I
do the same) - if you think about why, this is obvious. Also fixed our client
code to do level II oplocks, if requested, and fixed the code where we would
assume the client wanted level II if it advertised itself as being level II
capable - it may not want that.

b2d01bd2db totally rewrote the async signal, notification and oplock notification
handling in Samba. This was needed due to several limitations and
races in the previous code - as a side effect the new code is much
cleaner :)

in summary:

- changed sys_select() to avoid a signal/select race condition. It is a
  rare race but once we have signals doing notification and oplocks it
  is important.

- changed our main processing loop to take advantage of the new
  sys_select semantics

- split the notify code into implementaion dependent and general
  parts. Added the following structure that defines an implementation:

struct cnotify_fns {
	void * (*register_notify)(connection_struct *conn, char *path, uint32 flags);
	BOOL (*check_notify)(connection_struct *conn, uint16 vuid, char *path, uint32 flags, void *data, time_t t);
	void (*remove_notify)(void *data);
};


then I wrote two implementations, one using hash/poll (like our old
code) and the other using the new Linux kernel change notify. It
should be easy to add other change notify implementations by creating
a sructure of the above type.

- fixed a bug in change notify where we were returning the wrong error
  code.

- rewrote the core change notify code to be much simpler

- moved to real-time signals for leases and change notify

Amazingly, it all seems to work. I was very surprised!

8843a6379d Linux kernel oplocks now seem to work, but need a _lot_ of testing
I had to modify sys_select() to not loop on EINTR. I added a wrapper

e82dbfcbe9 Now that fsp's are created on successful file open, the structure member
fsp->open is no longer needed (if an fsp pointer is valid, then it's open :-).

identical w.r.t file serving with HEAD. This makes it impossible for
me to help maintain TNG. Please fix asap.

2fa922611b finally got sick of the "extern int Client" code and the stupid
assumption that we have one socket everywhere

while doing so I discovered a few bugs!

1) the clientgen session retarget code if used from smbd or nmbd would
cause a crash as it called close_sockets() which closed our main
socket! fixed by removing close_sockets() completely - it is unnecessary

2) the caching in client_addr() and client_name() was bogus - it could
easily get fooled and give the wrong result. fixed.

3) the retarget could could recurse, allowing an easy denial of
service attack on nmbd. fixed.

689ec46450 the bulk of the changes to get rid of fd_ptr and move print open
handling to printing/printing.c

most of this was just replacing things like fsp->fd_ptr->fd with fsp->fd

the changes in open.c are quite dramatic. Most of it is removing all
the functions that handled the fd multiplexing

4e1291a83f converted all our existing shared memory code to use a tdb database
instead of either sysv or mmap shared memory or lock files.

this means we can now completely remove
	locking_shm.c
	locking_slow.c
	shmem.c
	shmem_sysv.c
and lots of other things also got simpler

locking.c got a bit larger, but is much better compartmentalised now

053d6c605c at the interop Isaac (at least I _think_ it was Isaac) said that if a
MS client doesn't respond to a oplock break request then we might try
resending the request.

This morning Sues Win95 machine had this problem (thus forcing me to
do something about it!). When starting winword her box refused to
answer an oplock break request. I have added code to resend the oplock
break request up to 3 times at 10 second intervals before killing the
socket.

of course, as soon as I did this her box started to behave again so I
haven't been able to tell if this fix actually works, but it can't be
worse than dropping the socket immediately.
