Use a bit of talloc_steal and talloc_unlink to get the real socket to
be a child of the GENSEC or TLS socket.
Always return a new socket, even for the 'pass-though' case.

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.

correct, or we try and do a memcmp on the trailing '\0'.
This happens because we now use memcmp for the prefix matching.
I just wish I had a test other than a particular invocation of the OSX
client. (I've tried and failed so far)
Andrew Bartlett
(This used to be commit 36aa839080)
This reduces caller complexity, because the TLS code is now called
just like any other socket. (A new socket context is returned by the
tls_init_server and tls_init_client routines).
When TLS is not available, the original socket is returned.

Also trust OpenLDAP to be pedantic about it, breaking connections to AD.

GSSAPI differs from GSS-SPNEGO in an additional 3 packets, negotiating

I worked off draft-ietf-sasl-gssapi-03, and this works against Win2k3.
I'm doing this in the hope that Apple clients as well as SASL-based

Currently it doesn't to fallbacks like SPNEGO does, but this could be
added (to GENSEC, not to here).
This also adds a new function to GENSEC, which returns a list of SASL
names in our preference order (currently determined by the build
system of all things...).
Also make the similar function used for OIDs in SPNEGO do the same.
This is all a very long-winded way of moving from a hard-coded NTLM to

most of the changes are fixes to make all the ldb code compile without
warnings on gcc4. Unfortunately That required a lot of casts :-(
I have also added the start of an 'operational' module, which will
replace the timestamp module, plus add support for some other
operational attributes
In ldb_msg_*() I added some new utility functions to make the
operational module sane, and remove the 'ldb' argument from the
ldb_msg_add_*() functions. That argument was only needed back in the
early days of ldb when we didn't use the hierarchical talloc and thus
needed a place to get the allocation function from. Now its just a
pain to pass around everywhere.
Also added a ldb_debug_set() function that calls ldb_debug() plus sets
the result using ldb_set_errstring(). That saves on some awkward
coding in a few places.

requirements, and for better error reporting.
In particular, the composite session setup (extended security/SPNEGO)
code now returns errors, rather than NT_STATUS_NO_MEMORY. This is
seen particularly when GENSEC fails to start.
The tighter interface rules apply to NTLMSSP, which must be called
exactly the right number of times. This is to match some of our other
less-tested modules, where adding flexablity is harder. (and this is
security code, so let's just get it right). As such, the DCE/RPC and
LDAP clients have been updated.

(This used to be commit a9e8cd0bad)
quite a large change as we had lots of code that assumed that
objectSid was a string in S- format.
metze and simo tried to convince me to use NDR format months ago, but
I didn't listen, so its fair that I have the pain of fixing all the
code now :-)
This builds on the ldb_register_samba_handlers() and ldif handlers
code I did earlier this week. There are still three parts of this
conversion I have not finished:
- the ltdb index records need to use the string form of the objectSid
(to keep the DNs sane). Until that it done I have disabled indexing on
objectSid, which is a big performance hit, but allows us to pass
all our tests while I rejig the indexing system to use a externally
supplied conversion function
- I haven't yet put in place the code that allows client to use the
"S-xxx-yyy" form for objectSid in ldap search expressions. w2k3
supports this, presumably by looking for the "S-" prefix to
determine what type of objectSid form is being used by the client. I
have been working on ways to handle this, but am not happy with
them yet so they aren't part of this patch
- I need to change pidl to generate push functions that take a
"const void *" instead of a "void*" for the data pointer. That will
fix the couple of new warnings this code generates.
Luckily it many places the conversion to NDR formatted records
actually simplified the code, as it means we no longer need as many
calls to dom_sid_parse_talloc(). In some places it got more complex,
but not many.

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
(This used to be commit 3a3025485b)
- hooked into events system, so requests can be truly async and won't
interfere with other processing happening at the same time
- uses NTSTATUS codes for errors (previously errors were mostly
ignored). In a similar fashion to the DOS error handling, I have
reserved a range of the NTSTATUS code 32 bit space for LDAP error
codes, so a function can return a LDAP error code in a NTSTATUS
- much cleaner packet handling
(This used to be commit 2e3c660b2f)
ldif parsing code in libcli/ldap/ldap_ldif.c, and instead use the ldb
ldif code. To do that I have changed the ldap code to use 'struct
ldb_message_element' instead of 'struct ldap_attribute'. They are
essentially the same structure anyway, so by making them really the
same it will be much easier to use the ldb code in libcli/ldap/
I have also made 'struct ldb_val' the same as a DATA_BLOB, which will
simplify data handling in quite a few places (I haven't yet removed
all the code that maps between these two, that will come later)

instead of a search expression. This allows our ldap server to pass
its ASN.1 parsed search expressions straight to ldb, instead of going
via strings.

- got rid of the separate ldb_parse.h now that the ldb_parse
structures are exposed externally
- moved to C99 structure initialisation in ldb
- switched ldap server to using ldb_search_bytree()

(This used to be commit d5353b6342)
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').

less likely that anyone will use pstring for new code
- got rid of winbind_client.h from includes.h. This one triggered a

pstring and fstring.

files don't need to match the type names in the generated headers
- with this type mapping we no longer need definitions for the
deprecated "int32", "uint8" etc form of types. We can now force
everyone to use the standard types int32_t, uint8_t etc.
- fixed all the code that used the deprecated types
- converted the IDL types "int64" and "uint64" to "dlong" and
"udlong". These are the 4 byte aligned 64 bit integers that
Microsoft internally define as two 32 bit integers in a
structure. After discussions with Ronnie Sahlberg we decided that
calling these "int64" was confusing, as it implied a true 8 byte
aligned type
- fixed all the cases where we incorrectly used things like
"NTTIME_hyper" in our C code. The generated API now uses a NTTIME for
those. The fact that it is hyper-aligned on the wire is not relevant
to the API, and should remain just a IDL property
(This used to be commit f86521677d)
- added #if TALLOC_DEPRECATED around the _p functions
- fixes the code that broke from the above
while doing this I fixed quite a number of places that were
incorrectly using the non type-safe talloc functions to use the type
safe ones. Some were even doing multiplies for array allocation, which
is potentially unsafe.
(This used to be commit 6e7754abd0)

(disabled by default, set parametric option: gensec:gssapi=yes to enable).
This module backs directly onto GSSAPI, and allows us to sign and seal
GSSAPI/Krb5 connections in particular. This avoids me reinventing the
entire GSSAPI wheel.
Currently a lot of things are left as default - we will soon start
specifiying OIDs as well as passwords (it uses the keytab only at the
moment). Tested with our LDAP-* torture tests against Win2k3.
My hope is to use this module to access the new SPNEGO implementation
in Heimdal, to avoid having to standards-verify our own.

I have created the include/system/ directory, which will contain the
wrappers for the system includes for logical subsystems. So far I have
created include/system/kerberos.h and include/system/network.h, which
contain all the system includes for kerberos code and networking code.
These are the included in subsystems that need kerberos or networking
respectively.
Note that this method avoids the mess of #ifdef HAVE_XXX_H in every C
file, instead each C module includes the include/system/XXX.h file for
the logical system support it needs, and the details are kept isolated
in include/system/
This patch also creates a "struct ipv4_addr" which replaces "struct
in_addr" in our code. That avoids every C file needing to import all
the system networking headers.
(This used to be commit 2e25c71853)
taking a context (so when you pass a NULL pointer you end up with

(This used to be commit f12ee2f241)
btw, the reason I want to use strncasecmp() instead of StrnCaseCmp()
is that the Samba internal functions are built to deal with
multi-byte, whereas in the cases I am converting we know we are
dealing with solely ascii string constants, so going via the slow
conversion libraries is pointless.
(This used to be commit cef08d5789)
This version does the following:
1) talloc_free(), talloc_realloc() and talloc_steal() lose their
(redundent) first arguments
2) you can use _any_ talloc pointer as a talloc context to allocate
more memory. This allows you to create complex data structures
where the top level structure is the logical parent of the next
level down, and those are the parents of the level below
that. Then destroy either the lot with a single talloc_free() or
destroy any sub-part with a talloc_free() of that part
3) you can name any pointer. Use talloc_named() which is just like
talloc() but takes the printf style name argument as well as the
parent context and the size.
The whole thing ends up being a very simple piece of code, although
some of the pointer walking gets hairy.
So far, I'm just using the new talloc() like the old one. The next
step is to actually take advantage of the new interface
properly. Expect some new commits soon that simplify some common
coding styles in samba4 by using the new talloc().
