IPv6 in winbindd, but moves most of the socket functions that were
wrongly in lib/util.c into lib/util_sock.c and provides generic
IPv4/6 independent versions of most things. Still lots of work
to do, but now I can see how I'll fix the access check code.
Nasty part that remains is the name resolution code which is
used to returning arrays of in_addr structs.

InBuffer/OutBuffer
The complete history of this patch can be found under
http://www.samba.org/~vlendec/inbuf-checkin/.
Jeremy, Jerry: If possible I would like to see this in 3.2.0. I'm only
checking into 3_2 at the moment, as it currently will slow down operations for
all non-converted (i.e. all at this moment) operations, as it will copy the
talloc'ed inbuf over the global InBuffer. It will need quite a bit of effort
to convert everything necessary for the normal operations an XP box does.
I have patches for negprot, session setup, tcon_and_X, open_and_X, close. More
to come, but I would appreciate some help here.

that contains some of the fields from the SMB header, removing the need
to access inbuf directly. This right now is used only in the open file
code & friends, and creating that header is only done when needed. This
needs more work, but it is a start.
Jeremy, I'm only checking this into 3_0, please review before I merge it
to _26.

I'm 100% certain I've forgotten to merge something, but the main code
should be in. It's mainly in dbwrap_ctdb.c, ctdbd_conn.c and
messages_ctdbd.c.
There should be no changes to the non-cluster case, it does survive make
test on my laptop.
It survives some very basic tests with ctdbd enables, I did not do the
full test suite for clusters yet.
Phew...

This replaces the internal explicit dev/ino file id representation by a
"struct file_id". This is necessary as cluster file systems and NFS
don't necessarily assign the same device number to the shared file
system. With this structure in place we can now easily add different
schemes to map a file to a unique 64-bit device node.
Jeremy, you might note that I did not change the external interface of
smb_share_modes.c.

doing this because for the clustering the marshalling is needed in more
than one place, so I wanted a decent routine to marshall a message_rec
struct which was not there before.
Tridge, this seems about the same speed as it used to be before, the
librpc/ndr overhead in my tests was under the noise.

This changes "struct process_id" to "struct server_id", keeping both is

for utimes - change the call to ntimes. This preserves
nsec timestamps we get from stat (if the system supports
it) and only maps back down to usec or sec resolution
on time set. Looks bigger than it is as I had to move
lots of internal code from using time_t and struct utimebuf
to struct timespec.

based on the flags2 values in the negprot request.
This also includes some code for testing the dialect
strings for "SMB 2.001" but this is unreliable as Vista
only sends that in the 1st negprot and caches the fact
that we don't support it. Restartnig the WOrkstation
service on the client clears the cache.

event-driven
based approach. The only remaining hook into the backend is now
void *(*notify_add)(TALLOC_CTX *mem_ctx,
struct event_context *event_ctx,
files_struct *fsp, uint32 *filter);
(Should we put this through the VFS, so that others can more easily plug in?)
The trick here is that the backend can pick filter bits that the main smbd
should not handle anymore. Thanks to tridge for this idea.
The backend can notify the main smbd process via
void notify_fsp(files_struct *fsp, uint32 action, char *name);
The core patch is not big, what makes this more than 1800 lines are the
individual backends that are considerably changed but can be reviewed
one by one.
Based on this I'll continue with inotify now.

works - even with the strange "initial delete on close"
semantics. The "initial delete on close" flag isn't
committed to the share mode db until the handle is
closed, and is discarded if any real "delete on close"
was set. This allows me to remove the "initial_delete_on_close"
flag from the share db, and move it into a BOOL in files_struct.
Warning ! You must do a make clean after this. Cope with
the wrinkle in directory delete on close which is done
differently from files. We now pass all Samba4 smbtortute
BASE-DELETE tests except for the one checking that files
can't be created in a directory which has the delete on
close set (possibly expensive to fix).

survives the
first of the raw-notify subtests, the one-level test_notify_dir without any
flags around yet.
The tricky part was getting the data structures right, I hope the next tests
don't let that fall over.
fsp->notify is now by default NULL, meaning that nobody has issued a
changenotify call. This means nobody is interested in changes for this
directory.
If that has happened, notify_change_buf collects the changes if no current
request is outstanding, and it collects the requests if no change has happened
since the last request.
Happy New Year, somewhere on this planet it's already 2007 :-)
