a396b705c8 librpc:ndr: Introduce ‘ndr_flags_type’ type
Instead of ‘int’ or ‘uint32_t’, neither of which convey much meaning,
consistently use a newly added type to hold NDR_ flags.

Update the NDR 4.0.0 ABI.

c4f281e9ae librpc:ndr: Introduce ‘libndr_flags’ type
The LIBNDR_FLAG_ namespace is getting dangerously full, with only a
single flag value (1 << 9) remaining for use. After that flag is put
into use, we won’t be able to add any new flags without increasing the
flag width to 64‐bit.

Up to now we’ve used a haphazard mix of int, unsigned, and uint32_t to
store these flags. Introduce a new type, ‘libndr_flags’, to be used
consistently to hold LIBNDR flags. If in the future we find we need to
move to 64‐bit flags, this type gives us an opportunity to do that.

Bump the NDR version to 4.0.0 — an major version increment, for we’re
changing the function ABI and adding the new symbol
ndr_print_libndr_flags.

ae9d9434de librpc/wsp: adjust the wsp property api to additionally use a csv file
We have definitions for a number of properties both from the WSP
spec document and from those used by wireshark. These properties
are built into samba (generated from csv files). This commit allows
extra properties to be added on the fly in a custom csv file, the
format of the csv file is the same as that used in the build. This
allows us to add some 'unknown' properties on the fly, although we
would hope that information regarding these properties would be
incorporated into the build in due course.

f893cf85cc security.idl: extend security token for claims
A security token contains the context needed to make access decisions
for a particular client, which has until now been a number of SIDs and
flags. Claims are arbitrary attributes that can be tacked onto the
security token. Typically they will arrive via a Kerberos PAC, but we
don't need to worry about that now -- only that they are stored on the
token.

The security token in [MS-DTYP] 2.5.2 is described in abstract terms
(it is not transmitted on the wire) as behaving *as if* it held claims
in three arrays of CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1 structures. We
take that suggestion literally. This is *almost* the same as storing
the [MS-ADTS] 2.2.18 claims wire structures that the claims are
presumably derived from, and doing that might seem like a small
optimisation. But we don't do that because of subtle differences and
we already need CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1 in security.idl
for resource attribute ACEs.

The three stored claim types are user claims, device claims, and local
claims. Local claims relate to local Windows accounts and are unlikely
to occur in Samba. Nevertheless we have the array there just in case.

c73034cf7c librpc/security.idl: adjust size calculations for upcoming ace types
Soon we will get Conditional ACEs and Resource Attribute ACES, each of
which have trailing bytes at the end of the ACE. Here's a diagram:

              ____      The ACE size field may indicate a size bigger
  .type      /    |     than the known parts, even when you take
  .flags    /     |     rounding to a multiple of four into account.
  .size  --'      |     This extra data is meaningful in some ACEs.
  .access_mask    |
  .trustee (sid) _|  <- known data ends here.
                  :
   "coda"      ___:  <- the trailing part, Zero size unless the size
                        field points beyond the end of the known data.
			Probably empty for ordinary ACE types.

Until now we have thrown away these extra bytes, because they have no
meaning in the ACE types we recognise. But with conditional and
resource attribute ACEs we need to catch and process these bytes, so
we add an extra field for that.

Thus we can drop the manually written ndr_pull_security_ace() that
discarded the trailing bytes, because we just allow it to be pulled
into an unused blob. In the very common case, the blob will be empty.

Microsoft does not use a common name across different ACE types to
describe this end-data -- "coda" is a Samba term.

edad945339 librpc/nbt: Avoid reading invalid member of union
WACK packets use the ‘data’ member of the ‘nbt_rdata’ union, but they
claim to be a different type — NBT_QTYPE_NETBIOS — than would normally
be used with that union member. This means that if rr_type is equal to
NBT_QTYPE_NETBIOS, ndr_push_nbt_res_rec() has to guess which type the
structure really is by examining the data member. However, if the
structure is actually of a different type, that union member will not be
valid and accessing it will invoke undefined behaviour.

To fix this, eliminate all the guesswork and introduce a new type,
NBT_QTYPE_WACK, which can never appear on the wire, and which indicates
that although the ‘data’ union member should be used, the wire type is
actually NBT_QTYPE_NETBIOS.

This means that as far as NDR is concerned, the ‘netbios’ member of the
‘nbt_rdata’ union will consistently be used for all NBT_QTYPE_NETBIOS
structures; we shall no longer access the wrong member of the union.

963688b3a5 librpc: Always call ndr_push_compression_state_init() for compression
This allows the push routine to cache the chosen compression algorithm in
the struct ndr_compression_state in ndr->cstate and so, in claims, avoid
calling ndr_size_CLAIMS_SET_NDR() three times per compression (more in the
overall push).

As claims is now the primary use of the libndr compression code, this is
a reasonable tradeoff compared to the other callers who have more static
algorithm selections.

By removing the struct ndr_compression_state **state argument from
ndr_push_compression_state_init() we make clear that the ndr->cstate
belongs to this NDR context, and this context alone.

2e8e93fdd1 s4:kdc: Refactor PAC handling
It's getting unwieldy adding new PAC buffer types when each one has to
have its own handling. It also makes the possibility of mistakes more
likely.

Add a new container, 'struct pac_blobs', containing the types of PAC
buffers in a given PAC, with an index for quick access to the types we
support specifically. We can add new blobs (overriding existing ones) by
calling pac_blobs_add_blob(), and override certain blobs that must be
present with pac_blobs_replace_existing().

This removes the need to have a complicated 'switch' statement with
different logic for each PAC buffer type, or a dozen index variables.

e20067c52d auth: Make more liberal use of SID index constants
Arrays of SIDs are handled not fully consistently throughout the

user and a primary group respectively; other times they don't mean
anything in particular. Using these index constants in situations of the
former sort can help to clarify our intent.

The domain-local groups that are added to the PAC of a service ticket

If a client disconnected all its interfaces and reconnects when
the come back, it will likely start from any ip address returned
dns, which means it can try to connect to a different ctdb node.
The old node may not have noticed the disconnect and still holds
the client_guid based smbd.

Up unil now the new node returned NT_STATUS_NOT_SUPPORTED to
the SMB2 Negotiate request, as messaging_send_iov[_from]() will
return -1/ENOSYS if a file descriptor os passed to a process on
a different node.

Now we tell the other node to teardown all client connections
belonging to the client-guid.

Note that this is not authenticated, but if an attacker can
capture the client-guid, he can also inject TCP resets anyway,
to get the same effect.

0651fa474c dcesrv_core: wrap gensec_*() calls in [un]become_root() calls
This is important for the source3/rpc_server code as it might
be called embedded in smbd and may not run as root with access
to our private tdb/ldb files.

Note this is only really needed for 4.15 and older, as
we no longer run the rpc_server embedded in smbd,
but we better be consistent for now.

This should be able to fix the problem the printing no longer works
on Windows 7 with 2021-10 monthly rollup patch (KB5006743).

Windows uses NTLMSSP with privacy at the DCERPC layer on top
of NCACN_NP (smb).

da90c02b16 dcesrv_core: Add dcesrv_loop_next_packet()
This is used by the helpers of samba-dcerpcd: When accepting a DCERPC
client, normally the server engine would read the initial bind
packet. In case of samba-dcerpcd the bind packet will already be read
from the socket, so we need to inject it into the rpc server engine
externally.

95659031e4 backupkey.idl: Don't listen on \\pipe\ntsvcs
[MS-BKRP] says it SHOULD listen here. In the ad dc, this conflicts
with smbd's srv_ntsvcs_nt.c listening also on nt ntsvcs unix domain
socket. Because "samba" starts smbd after itself, smbd takes over the
socket anyway, backupkey can't have been reached over this transport.

1bab76223c librpc: Add named_pipe_auth_req_info5->transport
This will serve as a check to make sure that in particular a SAMR
client is really root. This is for example used in get_user_info_18()
handing out a machine password.

The unix domain sockets for NCACN_NP can only be contacted by root,
the "np\" subdirectory for those sockets is root/root 0700.

Connecting to such a socket is done in two situations: First, local
real root processes connecting and smbd on behalf of SMB clients
connecting to \\pipe\name, smbd does become_root() there. Via the
named_pipe_auth_req_info4 smbd hands over the SMB session information
that the RPC server blindly trusts. The session information (i.e. the
NT token) is heavily influenced by external sources like the KDC. It
is highly unlikely that we get a system token via SMB, but who knows,
this is information not fully controlled by smbd.

This is where this additional field in named_pipe_auth_req_info5 makes
a difference: This field is set to NCACN_NP by smbd's code, not
directly controlled by the clients. Other clients directly connecting
to a socket in "np\" is root anyway (only smbd can do become_root())
and can set this field to NCALRPC.

530fb4fdfb named_pipe_auth.idl: Add "need_idle_server"
Once RPC services are done by individual processes, we need to avoid
recursion between processes:

Any RPC server process will be able to serve multiple client requests
simultaneously, but each request is served in a single-threaded
blocking manner.

For example the netlogon RPC service needs to ask samr for
something. The netlogon->samr connection will initially be handled by
a central dispatcher assigning clients to processes. This dispatcher
needs to know that this connection can't end up in the same process
that originated the request.

With this flag an RPC client can request a samr server process that
exclusively serves its own requests and that will not serve anybody
else while serving netlogon.
