user_info strcture in auth/
This moves it to a pattern much like that found in ntvfs, with
functions to migrate between PAIN, HASH and RESPONSE passwords.
Instead of make_user_info*() functions, we simply fill in the control
block in the callers, per recent dicussions on the lists. This
removed a lot of data copies as well as error paths, as we can grab
much of it with talloc.

setup. Andrew, please check over this.
What happens is this:
- run the BASE-SECLEAK test
- with each failed session setup using spnego a gensec ctx is leaked into the smb_conn structure
- after the client disconnects these are finally cleaned up as they
are all children of the connection structure
- the cleanup of the millions of memory objects takes long enough
that the next operation in test_posix.sh sometimes fails with a timeout
Andrew, can you also look at the talloc_reference() on line 332 of
sesssetup.c ? I suspect it isn't needed (I don't think it does any
actual harm though)

"sam database"
set to the internal ldap server over loopback. The following happened:
- DCERPC_AUTH3 request
- auth requests calls ldb
- ldb calls ldap
- ldap calls our internal ldap server, triggering events
- samrConnect from client
- connect refused
- SMBclose from client
- causes dcerpc_pipe to be destroyed
- AUTH3 continues
- dies on freed pipe
I chose this solution as it provides a guarantee that backends only have to think about
async issues when they mark a request async. When they don't, this code guarantees that
a second request won't happen on the same connection while processing the first one

replay attacks under SMB signing, where the session key is a fixed
derivitive of the user's password.
This removes the VID offset, but I'm not worried about random client
bytes mattering here, given the space (and the fact that it applies to
very, very old clients).

event_context for the socket_connect() call, so that when things that
use dcerpc are running alongside anything else it doesn't block the
whole process during a connect.
Then of course I needed to change any code that created a dcerpc
connection (such as the auth code) to also take an event context, and
anything that called that and so on .... thus the size of the patch.
There were 3 places where I punted:
- abartlet wanted me to add a gensec_set_event_context() call
instead of adding it to the gensec init calls. Andrew, my
apologies for not doing this. I didn't do it as adding a new
parameter allowed me to catch all the callers with the
compiler. Now that its done, we could go back and use
gensec_set_event_context()
- the ejs code calls auth initialisation, which means it should pass
in the event context from the web server. I punted on that. Needs fixing.
- I used a NULL event context in dcom_get_pipe(). This is equivalent
to what we did already, but should be fixed to use a callers event
context. Jelmer, can you think of a clean way to do that?
I also cleaned up a couple of things:
- libnet_context_destroy() makes no sense. I removed it.
- removed some unused vars in various places

behaviour on session setups, and because we no longer need do deal
with the linked list as much, the code is much simpiler too.
We may be able to compleatly remove the tid and vuid linked lists, but
I need to check.
This patch also tries to clean up the VUID handling and session setups
in general. To avoid security issues, we now have a distinction
between VUIDs allocated for the session setup (to tie togeather the
multiple round trips) and those used after authentication.

GENSEC, and to pull SCHANNEL into GENSEC, by making it less 'special'.
GENSEC now no longer has it's own handling of 'set username' etc,
instead it uses cli_credentials calls.
In order to link the credentails code right though Samba, a lot of
interfaces have changed to remove 'username, domain, password'
arguments, and these have been replaced with a single 'struct
cli_credentials'.
In the session setup code, a new parameter 'workgroup' contains the
client/server current workgroup, which seems unrelated to the
authentication exchange (it was being filled in from the auth info).
This allows in particular kerberos to only call back for passwords
when it actually needs to perform the kinit.
The kerberos code has been modified not to use the SPNEGO provided
'principal name' (in the mechListMIC), but to instead use the name the
host was connected to as. This better matches Microsoft behaviour,
is more secure and allows better use of standard kerberos functions.
To achieve this, I made changes to our socket code so that the
hostname (before name resolution) is now recorded on the socket.
In schannel, most of the code from librpc/rpc/dcerpc_schannel.c is now
in libcli/auth/schannel.c, and it looks much more like a standard
GENSEC module. The actual sign/seal code moved to
libcli/auth/schannel_sign.c in a previous commit.
The schannel credentails structure is now merged with the rest of the
credentails, as many of the values (username, workstation, domain)
where already present there. This makes handling this in a generic
manner much easier, as there is no longer a custom entry-point.
The auth_domain module continues to be developed, but is now just as
functional as auth_winbind. The changes here are consequential to the
schannel changes.
The only removed function at this point is the RPC-LOGIN test
(simulating the load of a WinXP login), which needs much more work to
clean it up (it contains copies of too much code from all over the
torture suite, and I havn't been able to penetrate its 'structure').

refresh, release and query)
- change the iface_n_*() functions to return a "const char *" instead of a "struct ipv4_addr"
I think that in general we should move towards "const char *" for
all IP addresses, as this makes IPv6 much easier, and is also easier
to debug. Andrew, when you get a chance, could you fix some of the
auth code to use strings for IPs ?
- return a NTSTATUS error on bad name queries and node status instead
of using rcode. This makes the calling code simpler.
- added low level name release code in libcli/nbt/
- use a real IP in the register and wins nbt torture tests, as w2k3
WINS server silently rejects some operations that don't come from the
IP being used (eg. it says "yes" to a release, but does not in fact
release the name)

make it possible to add optimisations to the events code such as
keeping the next timed event in a sorted list, and using epoll for
file descriptor events.
I also removed the loop events code, as it wasn't being used anywhere,
and changed timed events to always be one-shot (as adding a new timed
event in the event handler is so easy to do if needed)

servers in smbd. The old code still contained a fairly bit of legacy
from the time when smbd was only handling SMB connection. The new code
gets rid of all of the smb_server specific code in smbd/, and creates
a much simpler infrastructures for new server code.
Major changes include:
- simplified the process model code a lot.
- got rid of the top level server and service structures
completely. The top level context is now the event_context. This
got rid of service.h and server.h completely (they were the most
confusing parts of the old code)
- added service_stream.[ch] for the helper functions that are
specific to stream type services (services that handle streams, and
use a logically separate process per connection)
- got rid of the builtin idle_handler code in the service logic, as
none of the servers were using it, and it can easily be handled by
a server in future by adding its own timed_event to the event
context.
- fixed some major memory leaks in the rpc server code.
- added registration of servers, rather than hard coding our list of
possible servers. This allows for servers as modules in the future.
- temporarily disabled the winbind code until I add the helper
functions for that type of server
- added error checking on service startup. If a configured server
fails to startup then smbd doesn't startup.
- cleaned up the command line handling in smbd, removing unused options

encapsulates all the different session setup methods, including the
multi-pass spnego code.
I have hooked this into all the places that previously used the
RAW_SESSSETUP_GENERIC method, and have removed the old
RAW_SESSSETUP_GENERIC code from clisession.c and clitree.c. A nice
side effect is that these two modules are now very simple again, back
to being "raw" session setup handling, which was what was originally
intended.
I have also used this to replace the session setup code in the
smb_composite_connect() code, and used that to build a very simple
replacement for smbcli_tree_full_connection().
As a result, smbclient, smbtorture and all our other SMB connection
code now goes via these composite async functions. That should give
them a good workout!
