- Check if the type simply as T_ prepended to the name.
- Don't put in a blurb of "NULL".

Subject: [PATCH 3/7] packet-spnego: fix decryption of DCERPC packets in
decrypt_gssapi_krb_cfx_wrap()
There the checksum and the encrypted data are no 2 different buffers
and we need to combine them before we try to rotate and decrypt them.

verified that we did have enough data in the buffer/tvb, which could
lead to a SEGV.
(for example if we enable KRB5 decryption but we do NOT use TCP
reassembly, and the encrypted data goes beyong the end of the current
segment)
Change the signature to decrypt_krb5_data() to take a TVB instead of a
buffer+length.
Actually check that we do have the entire encrypted PDU before calling
out to the kerberos libraries.

(1) Trailing/leading spaces are removed from 'name's/'blurb's
(2) Duplicate 'blurb's are replaced with NULL
(3) Empty ("") 'blurb's are replaced with NULL
(4) BASE_NONE, NULL, 0x0 are used for 'display', 'strings' and 'bitmask' fields
for FT_NONE, FT_BYTES, FT_IPv4, FT_IPv6, FT_ABSOLUTE_TIME, FT_RELATIVE_TIME,
FT_PROTOCOL, FT_STRING and FT_STRINGZ field types
(5) Only allow non-zero value for 'display' if 'bitmask' is non-zero

add a parameter *datalen to decrypt_krb5_data() so that we can pass back
the length of the decrypted blob back to the caller.
This is useful for when there are "junk" at the end of the blob and thus
the decrypted data is not the same size as the encrypted blob.
GSS CFX is one such example.
(we should have done this earlier since it might have made some other
stuff easier to imlement...)
make the preference setting krb_decrypt a globally visible variable so
we can see its value and act on it from callers of krb decryption from
outside of packet-kerberos.c i.e. from GSS CFX
Make keytype == -1 a wildcard that when passed to decrypt_krb5_data()
will try any/all encryption keys.
This since GSS CFX does not provide the enctype in the GSS layer.
(The GSS CFX enctype is only negotiated during the AP-REQ/REP so we
should later pick this value up and store it in a CFX session variable.
That is for a later enhancement.
)
Enhance the GSS decryption (that for hitorical reasons are implemented
in packet-spnego.c and not packet-gssapi.c :-) )
to also handle decryption of GSS CFX
This should make wireshark able to decrypt any/all GSSAPI RFC4121
packets, if the keytab file is provided.
I have successfully decrypted LDAP using GSS CFX with AES encryption
with this.

This is purely empirical as I can find no standard that says it should be there.
However successful LDAP/SASL/GSSAPI between AD and Java client shows it seems to be present.
If the confounder is not dissected, the LDAPMessage to fail to be decoded.
