p->mem_ctx is a relatively long lived context as it will not be freed until
a full request is served. In spoolss we do a lot of operations including
opening new pipes to connect to winreg.
Use more shortlived temporary contexts to avoid leaking a lot of memory on
p->mem_ctx and carrying it around untill all the operations in the current call
are done.

Put InternalPipes related functions in rpc_handles.c and out of rpc_ncacn_np.c
rpc_handles.c is the only file that really uses them after all and ncacn_np.c
is the wrong place for that stuff.
While ther remove unnecessary wrapper functions now that the InternalPipes
static variable is directly accessible.
Also move all pipes_struct related header stuff in its own rpc_pipes.h header.

Instead, we base our guest calculations on the presence or absense of the
authenticated users group in the token, ensuring that we have only
one canonical source of this important piece of authorization data

This is not required any more now that they are the same structure,
and shows the value in having a common structure across the codebase.
In particular, now any additional state that needs to be added to the
auth_session_info will be transparently available across the named
pipe proxy, without a need to modify the mapping layer.

This patch finally has the same structure being used to describe the
authorization data of a user across the whole codebase.
This will allow of our session handling to be accomplished with common code.

This makes auth3_session_info identical to auth_session_info
The logic to convert the info3 to a struct auth_user_info is
essentially moved up the stack from the named pipe proxy in
source3/rpc_server to create_local_token().
Andrew Bartlett

This ensures that the exact same token is used on both sides of the
pipe, when a full token is passed (ie, source3 to source3, but not yet
source4 to to source3 as the unix info isn't calculated there yet).
If we do not have unix_token, we fall back to the old behaviour and go
via create_local_token(). (However, in this case the security_token
is now overwritten, as it is better to have it match the rest of the
session_info create_local_token() builds).

This brings this structure one step closer to the struct auth_session_info.
A few SMB_ASSERT calls are added in some key places to ensure that
this pointer is initialised, to make tracing any bugs here easier in
future.
NOTE: Many of the users of this structure should be reviewed, as unix
and NT access checks are mixed in a way that should just be done using
the NT ACL. This patch has not changed this behaviour however.

This seperation between the structure used inside the auth modules and
in the wider codebase allows for a gradual migration from struct
auth_serversupplied_info -> struct auth_session_info (from auth.idl)
The idea here is that we keep a clear seperation between the structure
before and after the local groups, local user lookup and the session
key modifications have been processed, as the lack of this seperation
has caused issues in the past.

As auth_util.c is linked several times the static variables have
different address on different calls. This leads to segfaults.

The previous behaviour was to attempt to do a reverse hostname lookup,
where enabled. This new behaviour matches the new behaviour in the
modules called by auth stack.

TDB2 returns a negative error number on failure. This is compatible
if we always check for < 0 instead of == -1.
Also, there's no tdb_traverse_read in TDB2: we don't try to make
traverse reliable any more, so there are no write locks anyway.

r->out.buffer needs to stay in its size, as it will be marshalled completely.
As it's preallocated and initialized with zeros, we just need to copy
the payload into it, even if it's smaller than the offered buffer size.

If we always marshall the return buffer, we already have the needed
buffer size and don't need to call ndr_size_* functions.

And always initialize the whole return structure.

The client tell us in the rpc bind to which rpc service it wants to
connect. We did set the p->syntax earlier by guessing to which pipe name
it connects, but we don't know to which rpc service it wants to bind
until we read the first packet.
This provides the 'sconn' parameter to this key functions, that
is currently duplicated in dummysmbd.c, which causes duplicate symbol
issues in the waf build.
This has natrually caused a number of consequential changes across the
codebase, includning not passing a messaging context into initial
reload_services():
This causes problems because the global smbd_server_connection isn't
yet set up, as there isn't a connection here, just the initial
process.
Andrew Bartlett
With the recent consolidation of code between s3 and s4, a number of new
dependencies have been implicitly introduced. For example, previous s3
code gained an implicit dependency on talloc after the charset related
consolidation (lib/util/charset/charset.h now includes talloc.h). When
building against the embedded version of talloc this isn't a problem
since the paths are automatically added to the search path, but when
building against the external libraries build failures will occur for
all components that don't directly or indirectly include talloc as
a dependency.
Since charset.h is included from util.h, which in turn is included from
includes.h, this means most of the codebase (s3 and s4) has such an
undeclared dependency.
Therefore, samba-util-common and samba-util have been added as
dependencies to the s3 and s4 code respectively, for all cases where
the source would otherwise fail to build. Additionally, a few other
dependencies are added in specific wscript_build files to address
similar dependency-related problems.

This only works for Heimdal and MIT Krb5 1.8, other versions will get
an ACCESS_DEINED error.
We no longer manually verify any details of the PAC in Samba for
GSSAPI logins, as we never had the information to do it properly, and
it is better to have the GSSAPI library handle it.
Andrew Bartlett
This Heimdal function does not set the global state, and allows the
GSSAPI server to progress further when compiled against Heimdal (such
as in the top level build).
The ability to specify a keytab has been removed from the API as it is
unused, and and the Heimdal function (avoiding setting global
variables) works with an open keytab.
