575d39048e idl: limit recurion on recursive elements
Limit the max_recursion on self recursive definitions in the idl to
20,000. This value is hopefully large eneough to not impact normal
operation, but small eneough to prevent stack over flow issues.

This simply matches the behaviour from before e7b1acaddf
when the logic for a trailing . was added.  This matches what is added in
the dnsRecord attribute for a name of "." over the dnsserver RPC
management interface and is based on what Windows does for that name
in (eg) an MX record.

No a security bug because we use talloc and so name will be just the
end of the talloc header.

fee5c6a424 librpc/idl/dnsserver.idl: Ensure DnsProperty id matches what is pulled from the stored buffer
There are two concerns here, assuming the attacker can place arbitary values
in a dnsProperty attribute over LDAP (eg is a DNS administrator).

This comes from the fact that id is used as the switch value at the C layer
but at the NDR layer the wDataLength value is considered first.

One concern is that a pull/push round-trip could include server memory:

 The previous switch_is() behaviour could store the server memory back
 into the attribute.

 However this pattern of pull/push only happens in ndrdump and fuzzing tools, as
 dnsserver_db_do_reset_dword() operates only on the uint32/bitmap union
 arms, and fully initialises those.

The other is that a pull of the attacker-supplied value could
cause the server to expose memory.

 This would be over the network via DNS or the RPC dnsserver protocols.
 However at all times the ndr_pull_struct_blob is passed zeroed memory.

The final concern (which fuzz_ndr_X found) is that in the ndr_size_dnsPropertyData()
the union descriminent is only id.

 This has no impact as only zeroed memory is used so there will be a
 zero value in all scalars, including data->d_ns_servers.AddrArray.

 Therefore the server will not crash processing the attacker-supplied blob

[MS-DNSP] 2.3.2.1 dnsProperty has no mention of this special behaviour.
https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-dnsp/445c7843-e4a1-4222-8c0f-630c230a4c80

This was known as CVE-2019-14908 before being triaged back to a normal bug.

Found by Douglas Bagnall using Hongfuzz and the new fuzz_ndr_X fuzzer.

7b265830ad lib/fuzzing: add fuzz_ndr_X
This NDR fuzzer links with each "interface" in the IDL files to
create avsingle binary.  This tries to matches what the fuzzing
engines desire.

It started as a copy of ndrdump but very little of that remains
in place.

The fancy build rules try to avoid needing a lof of boilerplate
in the wscript_build files and ensure new fuzzers are generated
and run when new IDL is added automatically.

bd81733bb7 librpc: Make CFDATA private to cab.idl and remove pull and push functions
We can do this because ndr_{pull,push}_CFDATA is unused.

The earlier commit 466d5e8147 removed
the link between "uint16 cbData" and the size of "DATA_BLOB ab" so
when the new ndr_fuzz_X fusser pushed a new structure this allowed
a read beyond the end of allocated memory.

The ndr_push_cab_file() function is also manually written and
does not rely on the value of cbData to calculate the checksum.

Found by Douglas Bagnall using Hongfuzz and the new fuzz_ndr_X
fuzzer, which like ndrdump's struct mode uses the public structure
tables.  (This is how it found the unused functions to test).

dfbb304958 ndrdump: add --stop-on-parse-failure
If a data stream fails to parse as an NDR object, the default ndrdump
action is to try to print those structures anyway, resulting perhaps in
a NULL dereference. Sometimes you don't want to see that because it isn't
very interesting and makes it harder to distinguish a crash in the parse
routines. So --stop-on-parse-failure will skip the print and validate
stages altogether if the parse failed.

6fc7cc1504 dnsp.idl: fix the dnsp_dns_addr_array definition

from the blobs Windows generated (see the torture test):

  AddrArray: ARRAY(3)
      AddrArray: struct dnsp_dns_addr
          family                   : 0x0002 (2)
          port                     : 0x0035 (53)

[MS-DNSP] states that the port is supposed to be ignored, but it's still
good to decode it as port '53' (0x0035) instead of '13568' (0x3500).

96e6adedcd librpc idl: netlogon netr_identity_info logon_id to 64 bit
Fold the two 32 bit values logon_id_high and logon_id_low into a single
64 bit logon_id in netr_identity_info.  This will be used to tie
together winbind and SamLogon requests in audit logging.

Summary of the of the Query and Response from Microsoft on it's usage.

[REG:119013019612095] [MS-NRPC]: NETLOGON_LOGON_IDENTITY_INFO: Does
the Reserved field have LogonId meaning?

Questions:
  In NetrLogonSamLogonEx does the Reserved field
  (of NETLOGON_LOGON_IDENTITY_INFO) have LogonId meaning?

  What is a valid LogonID, and does have any audit usage?

  Samba is sending a constant "deadbeef" in hex and would like to
  understand any usage of this field.

Response:
  The NRPC spec is accurate in defining the field as Reserved, and without
  protocol significance. In the header file in our source code, it is
  defined as LogonId and commented as such, but it’s effectively not used.
  This is probably why the API structure has that field name. It may have
  been intended as such but it’s not used.

Samba will send a random value in this field.
