The timout for the cache entry of a negative connection should be the

This defines a common table format, so we can in future define a
common table.

This is the s3 debug system, with a number of changes to tidy it up
for common use. The debug class system is simplified by the removal of the
ISSET table, the system no longer attempts to cope with assignment of
DEBUGLEVEL, and the full class table is always available (rather than
just DEBUGLEVEL_CLASS[DBCG_ALL]) from startup. It is also no longer
confusingly described as a hack, but as the initial table.

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.

is incorrect.
(I based it on the text in MS-SMB2, silly me :-). Fix it so incoming sequence numbers
can range over the entire allowable bitmap range. This fixes a repeatable
disconnect against Win7.

Parts of the Samba RPC client and server code misinterpret authenticated
packets.
DCE authenticated packets actually look like this :
+--------------------------+
|header |
| ... frag_len (packet len)|
| ... auth_len |
+--------------------------+
| |
| Data payload |
... ....
| |
+--------------------------+
| |
| auth_pad_len bytes |
+--------------------------+
| |
| Auth footer |
| auth_pad_len value |
+--------------------------+
| |
| Auth payload |
| (auth_len bytes long) |
+--------------------------+
That's right. The pad bytes come *before* the footer specifying how many pad
bytes there are. In order to read this you must seek to the end of the packet
and subtract the auth_len (in the packet header) and the auth footer length (a
known value).
The client and server code gets this right (mostly) in 3.0.x -> 3.4.x so long
as the pad alignment is on an 8 byte boundary (there are some special cases in
the code for this).
Tridge discovered there are some (DRS replication) cases where on 64-bit
machines where the pad alignment is on a 16-byte boundary. This breaks the
existing S3 hand-optimized rpc code.
This patch removes all the special cases in client and server code, and allows
the pad alignment for generated packets to be specified by changing a constant
in include/local.h (this doesn't affect received packets, the new code always
handles them correctly whatever pad alignment is used).
This patch also works correctly with rpcclient using sign+seal from
the 3.4.x and 3.3.x builds (testing with 3.0.x and 3.2.x to follow)
so even as a server it should still work with older libsmbclient and
winbindd code.

this allows us to experiment with ensuring the tdb hash
size for our open files and locking db are appropriately
sized. Make the hash size larger by default (10007 instead
of 1049) and make the locking db hash size the same as the
open file db hash size.

the pam password change code to ensure that existing and working password
chat scripts don't break with 2.2.1. PAM password changing has to be explicitly
requested.
Allowed wildcards in pam password change matching (matches password chat
script matching). Had to add const (sorry Tim :-) to ms_fnmatch() to
stop warnings. Don't worry - the const changes are isolated and don't
cause any other warnings :-).

- removes SMB_ALIGNMENT. That macro caused all sorts of problems with
getting unicode aligned right in sub-protocols (such as SMBtrans and
SMBtrans2). I believe the performance reasons for having
SMB_ALIGNMENT has gone away with the new variants of the SMB
protocol anyway, as newer commands tend to have their own internal
alignment.
- fix the locations where we set smb_flg2 to absolute values. We must
never do this if we want a hope of coping with unicode.
- add initial support for unicode on the wire in smbd. Currently
enabled using SMBD_USE_UNICODE environment variable.

this means "nmblookup -S" now always works, even with broken servers
the database stores all unexpected replies and these can be accessed
by any client.
while doing this I cleaned up a couple of functions, and put in place
a better trn_id generator. in most places the code got quite a bit
simpler due to the addition of simple helper functions.
I haven't yet put the code in to take advantage of this for pdc
replies - that will be next. Jeremys pdc finding code will then work :)
