I only commit this as this is used in a global macro
tridge: we should try to get rid of this warning without using
(void)talloc_steal(ctx, ptr);
everywhere!!!

request. The problem is that the talloc_free() in
smbsrv_send_reply_nosign() frees this reference, but doesn't free the
memory iself, thus leaving it attached to the connection context.
Metze, what was the idea behind this reference? If we need it, then we
need a corresponding talloc_free() to go with it.
- to use a struct ntvfs_handle instead of a uint16_t fnum.
(to make it independend from the frontend protocol)
- the allocation of handles now is provided by the frontend
(smbsrv_*) via callbacks and not by each backend module
- this also makes sure that file handles are only passed
to the ntvfs subsystem when the tcon and session matches,
so modules can rely on this and need to check this.
- this allows multiple modules in the ntvfs module chain
to allocate file handles. This can be used for virtual
files like "\\$Extend\\$Quota:$Q:$INDEX_ALLOCATION"...
- also this will make SMB2 with 128 bit file handles possible

(for now we just do #define ntvfs_request smbsrv_request,
but it's the first step...)
- rename ntvfs_openfile() -> ntvfs_open()
- fix the talloc hierachie in some places in the ntvfs_map_*() code

- add an idtree_limit to limit the max VUID we give the clients
it's UINT16_MAX (0xffff) for the SMB protocol
- add auth_time to the smbsrv_session statistics
- use the session_info as marker for finished and non-finished
session setups

them
- add a idtree_limit to the tcons substructure of smbsrv_connection
this controls what the highest TID is we give away to the client
it's UINT16_MAX (0xFFFF) for the SMB protocol

authentication. This pulls the creating of the keytab back to the
credentials code, and removes the special case of 'use keberos keytab
= yes' for now.
This allows (and requires) the callers to specify the credentials for
the server credentails to GENSEC. This allows kpasswdd (soon to be
added) to use a different set of kerberos credentials.
The 'use kerberos keytab' code will be moved into the credentials
layer, as the layers below now expect a keytab.
We also now allow for the old secret to be stored into the
credentials, allowing service password changes.

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
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.

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
- stream_socket services
the smb, ldap and rpc service which sets up a srtam socket end then
waits for connections
and
- task services
which this you can create a seperate task that do something
(this is also going through the process_model subsystem
so with -M standard a new process for this created
with -M thread a new thread ...
I'll add datagram services later when we whave support for datagram sockets in lib/socket/
see the next commit as an example for service_task's
