specific debug function.
By default do not debug, this is the most appropriate action for a library
as we cannot assume what stderr is use for in the main app.
The main app is responsible to set ev_debug_stderr if they so desire.

To use, run 'smbd -M prefork'
By default, only the smb service is preforked. 4 children are
created, and all listen for new connections. The Linux Kernel 'wake
one' behaviour should ensure that only one is given the oportunity to
accept. We need to look into the ideal number of worker children, as
well as load balancing behaviours.
To change, set:
prefork children : smb = 6
valid service names (smb in this example) match those in 'server services'.

Applications that use LDB modules will now have to run ldb_global_init()
before they can use LDB.
The next step will be adding support for loading LDB modules from .so
files. This will also allow us to use one LDB without difference between the
standalone and the Samba-specific build

good, as it is probably a resource constraint, so if we just try again
we will spin (as the incoming socket will still be readable). Using a
sleep(1) solves this by throtting smbd until the resource constraint
goes away.
if the resource constraint doesn't go away, then at least smbd won't
be spinning chewing cpu

decide to reinstate the mutex code for the threads process model, I'd
like to do it a little differently. At least this gets it out of
includes.h for now.

themselves are run as a single process, but run as a child of the
main process when smbd is run in the standard model, and run as part
of the main process when in the single mode.
- rewrote the winbind template code to use the new task services. Also
fixed the packet queueing
- got rid of event_context_merge() as it is no longer needed
(This used to be commit 339964a596)
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

because the version number was being auto-updated and included in all
C files. With this change it is only included where needed.
(This used to be commit 520cff73c6)
- 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

- use #include <XXX.h> for operating system includes
- use includes relative to include/ for things like system/wait.h
also fixed the thread backend to work somewhat. To fix it properly we need to do this:
- add a configure test for support for thread local storage (the __thread keyword)
- refuse to do pthreads if tls doesn't work
- refuse to do pthreads if seteuid() affects process instead of thread
- defined THREAD_LOCAL as __thread when WITH_PTHREADS
- add THREAD_LOCAL to all the global data structures that should be
thread local (there are quite a few)
right now the thread backend falls over when you hit it with several
connections at once, due to the lack of __thread on some critical
structures.
(This used to be commit 0dc1deabd0)
you set this option (either on the command line using --option or in
smb.conf) then every socket recv or send will return short by random
amounts. This allows you to test that the non-blocking socket logic in
your code works correctly.
I also removed the flags argument to socket_accept(), and instead made
the new socket inherit the flags of the old socket, which makes more
sense to me.
(This used to be commit 406d356e69)
- added the new messaging system, based on unix domain sockets. It
gets over 10k messages/second on my laptop without any socket
cacheing, which is better than I expected.
- added a LOCAL-MESSAGING torture test
(This used to be commit 3af06478da)
connection termination cleanup, and to ensure that the event
contexts are properly removed for every process model
- gave auth_context the new talloc treatment, which removes another
source of memory leaks.
(This used to be commit 230e1cd777)
the idea is to have services as modules (smb, dcerpc, swat, ...)
the process_model don't know about the service it self anymore.
TODO:
- the smbsrv should use the smbsrv_send function
- the service subsystem init should be done like for other modules
- we need to have a generic socket subsystem, which handle stream, datagram,
and virtuell other sockets( e.g. for the ntvfs_ipc module to connect to the dcerpc server
, or for smb or dcerpc or whatever to connect to a server wide auth service)
- and other fixes...
NOTE: process model pthread seems to be broken( but also before this patch!)

(This used to be commit bbe5e00715)
because this is the connection state per transport layer (tcp)

I also moved the substructs directly into smbsrv_connection,
because they don't need a struct name and we should allway pass the complete
smbsrv_connection struct into functions

I plan to convert all objectfile group to use SMB_SUBSYSTEM
later I'll add a SMB_BINARY() and SMB_LIBRARY(), then there will be no more need
to touch Makefile.in, because all make rules will be autogenerated by configure
- convert the PROCESS_MODEL subsystem to this new scheme
and move the pthread test to smbd/process_model.m4
- convert the CHARSET subsystem to this new scheme
and move the iconv test to lib/iconv.m4

1.) We now register endpoint servers add startup via register_backend()
and later use the smb.conf 'dcerpc endpoint servers' parameter to setup the dcesrv_context
2.) each endpoint server can register at context creation time as much interfaces as it wants
(multiple interfaces on one endpoint are supported!)
(NOTE: there's a difference between 'endpoint server' and 'endpoint'!
for details look at rpc_server/dcesrv_server.h)
3.) one endpoint can have a security descriptor registered to it self
this will be checked in the future when a client wants to connect
to an smb pipe endpoint.
4.) we now have a 'remote' endpoint server, which works like the ntvfs_cifs module
it takes this options in the [globals] section:
dcerpc remote:interfaces = srvsvc, winreg, w32time, epmapper
dcerpc remote:binding = ...
dcerpc remote:user = ...
dcerpc remote:password = ...
5.) we currently have tree endpoint servers: epmapper, rpcecho and remote
the default for the 'dcerpc endpiont servers = epmapper, rpcecho'
for testing you can also do
dcerpc endpoint servers = rpcecho, remote, epmapper
dcerpc remote:interfaces = srvsvc, samr, netlogon
6,) please notice the the epmapper now only returns NO_ENTRIES
(but I think we'll find a solution for this too:-)
7.) also there're some other stuff left, but step by step :-)
This patch also includes updates for the
register_subsystem() , ntvfs_init(), and some other funtions
to check for duplicate subsystem registration
