Since commit 7022554, smbds share a printcap cache (printer_list.tdb),
therefore ordering of events between smbd processes is important when
updating printcap cache information. Consider the following two process
example:
1) smbd1 receives HUP or printcap cache time expiry
2) smbd1 checks whether pcap needs refresh, it does
3) smbd1 marks pcap as refreshed
4) smbd1 forks child1 to obtain cups printer info
5) smbd2 receives HUP or printcap cache time expiry
6) smbd2 checks whether pcap needs refresh, it does not (due to step 3)
7) smbd2 reloads printer shares prior to child1 completion (stale pcap)
8) child1 completion, pcap cache (printer_list.tdb) is updated by smbd1
9) smbd1 reloads printer shares based on new pcap information
In this case both smbd1 and smbd2 are reliant on the pcap update
performed on child1 completion.
The prior commit "reload shares after pcap cache fill" ensures that
smbd1 only reloads printer shares following pcap update, however smbd2
continues to present shares based on stale pcap data.
This commit addresses the above problem by driving pcap cache and
printer share updates from the parent smbd process.
1) smbd0 (parent) receives a HUP or printcap cache time expiry
2) smbd0 forks child0 to obtain cups printer info
3) child0 completion, pcap cache (printer_list.tdb) is updated by smbd0
4) smbd0 reloads printer shares
5) smbd0 notifies child smbds of pcap update via message_send_all()
6) child smbds read fresh pcap data and reload printer shares
This architecture has the additional advantage that only a single
process (the parent smbd) requests printer information from the printcap
backend.
Use time_mono in housekeeping functions As suggested by Björn Jacke.

This breaks the perfcol_onefs() build.
Tim, Steve, this use of smbd_server_fd is replacable by calls into
substitute.c. I don't have a onefs environment around to build a fix, so I've
decided to insert an #error, making it not compile. The fix should be pretty
obvious, you can get the socket data via "%I" and "%i" substitutions.

This moves those arrays from dynamic to static, shared memory, removing them
from globals.c.
I did it by dumping the result of init_tables() with dump_data(). Some massage
by an editor macro made it the initializer.

into negprot_spnego() where it belongs (it's not an SPNEGO operation).
Add a TALLOC_CTX for callers of negprot_spnego(). Closer to unifying all
the gen_negTokenXXX calls.

Volker pointed out I'd missed the "last directory" cache
part of this code. Return us to caching the directory we're
in (reduces sys call load).
Mea maxima culpa.

It would be obvious to initialize this in smbd_init_globals(), but there the
messaging_context can't be initialized yet because we don't have smb.conf
loaded yet.

If a file is closed we must also NULL out all chained_fsp
pointers when the fsp is freed to prevent invalid pointer
access.

The my_yp_domain variable is just a static cache needed to avoid
making over and over expensive and potentially blocking calls to
yp_get_default_domain().
Instead of keeping this onto the smbd_server_connection struct, just
keep it local to the only function ever using this variable.
This disentagle this function (and a number of calling functions)
from having to pass around smbd_server_connection and thus having
to link against smbd. It also removes a few ifdefs.
Nothing changes from a global/local pov, as the smbd_server_connection
variable passed around is also a global one.

64-bit Vista client
It turns out that the persistent handles are used by the Microsoft
redirector to index files on oplock break requests. So even if we
don't do durable handles (yet) we must set the persistent handle
on create. For now just use the same handle value as we use for
volatile.

Metze, you'll probably be happier with this work as it
doesn't abuse tevent in the way you dislike. This is a
first cut at the code, which will need lots of testing
but I'm hoping this will give people an idea of where I'm
going with this.

Makes SMB2Create call re-entrant internally.
Now this infrastructure is in place, oplocks will follow shortly.
Tested with Win7 client and with W2K8R2.

right.
Gets us handling SMB2 compound async requests similar to W2K8R2
(and triggers the same client bug in the Win7 redirector). Great
thanks to Ira Cooper <samba@ira.wakeful.net> for helping with
this and to Metze for the wonderful async framework. The one
thing I need to fix to make us identical to W2K8R2 is that
when a compound request goes async at the end W2K8R2 splits
the replies up into a compound non-async reply followed by
a separate async reply. Currently we're doing the whole thing
in a compound reply.

This will allow us to share logic much easier between SMB1 and SMB2
servers.

Rename functions to be internally consistent. Next step is
to cope queueing single (non-compounded) SMB2 requests to
put some code inside the stubs.

Allocate a uint16_t internal SMB1 mid for an SMB2 request.
Add a back pointer from the faked up smb_request struct
to the smb2 request.
Getting ready to add restart code for blocking locks,

Remove the bool ms_dfs_link parameter from smbd_do_qfilepathinfo.
It is not possible for this to be a DFS link. Remove the check_msdfs_link()
call from call_trans2qfilepathinfo() - the call to filename_convert()
above with a ucf_flags of zero *MUST* catch a DFS link and return
NT_STATUS_PATH_NOT_COVERED in this case, so the code below checking
for msdfs links is redundent. Don't add this to 3.5.x, as it's an
optimization but not needed to fix bug #7339 - MSDFS is non-functional in 3.5.x.
