The problem was that the parent smbd doesn't have
any event when the process model standard was in use.
Now we always add an fd event for stdin, but may not
ask for any events to trigger.

The problem here was that with the packet code set to serialise, we
can have multiple packets 'processing' at once, and previously the
second packet (allowed because we are spining on an event context down
the stack) would clear the flag.

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.

NULL represents an anoymous connection, as that's
cheaper than always calling auth_anonymous_session_info(),
That means if the caller wants to use the transport layer
session_info he should call auth_anonymous_session_info()
to create the session info.

Fix talloc_steal in both cases to steal connected socket (from accept)

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'.

been working on for at least half a year now. Contains the following
improvements:
* proper layering (finally!) for the registry library. Distinction is
now made between 'real' backends (local, remote, wine, etc) and
the low-level hive backends (regf, creg, ldb, ...) that are only used
by the local registry backend
* tests for all important hive and registry operations
* re-enable RPC-WINREG tests (still needs more work though, as
some return values aren't checked yet)
* write support for REGF files
* dir backend now supports setting/reading values, creating keys
* support for storing security descriptors
* remove CREG backend as it was incomplete, didn't match the data model
and wasn't used at all anyway
* support for parsing ADM files as used by the policy editor (see lib/policy)
* support for parsing PREG files (format used by .POL files)
* new streaming interface for registry diffs (improves speed and memory usage
for regdiff/regpatch significantly)
... and fixes a large number of bugs in the registry code

This merges Samba4 with lorikeet-heimdal, which itself has been
tracking Heimdal CVS for the past couple of weeks.
This is such a big change because Heimdal reorganised it's internal
structures, with the mechglue merge, and because many of our 'wishes' have been granted: we now have DCE_STYLE GSSAPI, send_to_kdc hooks and many other features merged into the mainline code. We have adapted to upstream's choice of API in these cases.
In gensec_gssapi and gensec_krb5, we either expect a valid PAC, or NO
PAC. This matches windows behavour. We also have an option to
require the PAC to be present (which allows us to automate the testing
of this code).
This also includes a restructure of how the kerberos dependencies are
handled, due to the fallout of the merge.

contexts from the application layer into the socket layer.
This improves a number of correctness aspects, as we now allow LDAP
packets to cross multiple SASL packets. It should also make it much
easier to write async LDAP tests from windows clients, as they use SASL
by default. It is also vital to allowing OpenLDAP clients to use GSSAPI
against Samba4, as it negotiates a rather small SASL buffer size.
This patch mirrors the earlier work done to move TLS into the socket
layer.
Unusual in this pstch is the extra read callback argument I take. As
SASL is a layer on top of a socket, it is entirely possible for the
SASL layer to drain a socket dry, but for the caller not to have read
all the decrypted data. This would leave the system without an event
to restart the read (as the socket is dry).
As such, I re-invoke the read handler from a timed callback, which
should trigger on the next running of the event loop. I believe that
the TLS code does require a similar callback.
In trying to understand why this is required, imagine a SASL-encrypted
LDAP packet in the following formation:
+-----------------+---------------------+
| SASL Packet #1 | SASL Packet #2 |
----------------------------------------+
| LDAP Packet #1 | LDAP Packet #2 |
----------------------------------------+
In the old code, this was illegal, but it is perfectly standard
SASL-encrypted LDAP. Without the callback, we would read and process
the first LDAP packet, and the SASL code would have read the second SASL
packet (to decrypt enough data for the LDAP packet), and no data would
remain on the socket.
Without data on the socket, read events stop. That is why I add timed
events, until the SASL buffer is drained.
Another approach would be to add a hack to the event system, to have it
pretend there remained data to read off the network (but that is ugly).
In improving the code, to handle more real-world cases, I've been able
to remove almost all the special-cases in the testnonblock code. The
only special case is that we must use a deterministic partial packet
when calling send, rather than a random length. (1 + n/2). This is
needed because of the way the SASL and TLS code works, and the 'resend
on failure' requirements.

It will take a minute or so to generate all the dependency information,
but there should be no need to rebuild that information later on, unless
a file changes.
This behaviour is only enabled when building in developer mode
(--enable-developer) and requires a GNU make (or compatible). In all other
cases, the file 'static_deps.mk' is included, which contains some basic
hardcoded dependency information.

structure that is more generic than just 'IP/port'.
It now passes make test, and has been reviewed and updated by
metze. (Thankyou *very* much).
This passes 'make test' as well as kerberos use (not currently in the
testsuite).
The original purpose of this patch was to have Samba able to pass a
socket address stucture from the BSD layer into the kerberos routines
and back again. It also removes nbt_peer_addr, which was being used
for a similar purpose.
It is a large change, but worthwhile I feel.

We now use a different system for initializing the modules for a subsystem.
Most subsystems now have an init function that looks something like this:
init_module_fn static_init[] = STATIC_AUTH_MODULES;
init_module_fn *shared_init = load_samba_modules(NULL, "auth");
run_init_functions(static_init);
run_init_functions(shared_init);
talloc_free(shared_init);
I hope to eliminate the other init functions later on (the
init_programname_subsystems; defines).

This is the start of a WINS-Replicaton server:
The design is to handle incoming and outgoing connections,
in one process, because it make thing much easier, and there's
no need to it otherwise.
The current code only parses incoming packets, and can reply
to them, but currently only a standard error packets STOP_ASSOCIATON

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

There is now a new --debug-stderr option to enable debug to STDERR.
popt isn't perfect, but the callbacks are used in all the main Samba
binaries, and should be used in the rest. This avoids duplicated
code, and ensures every binary is setup correctly.
This also ensures the setup happens early enough to have -s function,
and have a correct impact on the credentials code. (Fixing a bug that
frustrated tridge earlier today).
The only 'subtle' aspect of all this is that I'm pretty sure that the
SAMBA_COMMON popt code must be above the CREDENTIALS code, in the
popt tables.

- if you want kerberos now, you need to unpack a lorikeet heimdal
tree in source/heimdal/. If source/heimdal/ does not exist at
configure time then all kerberos features are disabled. You cannot
use an external kerberos library for now. That may change later.
- moved lib/replace/ config stuff to lib/replace/ and create a
lib/replace/replace.h. That allows the heimdal build to use our
portability layer, and prevenets duplicate definitions of functions
like strlcat()
- if you do enable heimdal, then you will need to do 'make
HEIMDAL_EXTERNAL' before you build Samba. That should be fixed once
I explain the problem to jelmer (the problem is the inability to
set a depend without also dragging in the object list of the
dependency. We need this for building the heimdal asn1 compiler and
et compiler.
- disabled all of the m4 checks for external kerberos libraries. I
left them in place in auth/kerberos/, but disabled it in
configure.in
some of the heimdal_build/ code is still very rough, for example I
don't correctly detect the correct awk, flex, bison replacements for
heimdal_build/build_external.sh. I expect to fix that stuff up over
the next few days.

management system I proposed on samba-technical a couple of days
ago. Essentially it is a very lightweight way for any code in Samba to
make IDL based rpc calls to anywhere else in the code, without the
client or server having to go to the trouble of setting up a full rpc
service.
It can be used with any of our existing IDL, but I expect it will
mostly be used for a new set of Samba specific management calls.
The LOCAL-IRPC torture test demonstrates how it can be used by calling
the echo_AddOne() call over this transport.
