Hi folks, to fix the LDAP SASL integrity only stuff, I think I have to do something like the following: --- a/asn1/spnego/packet-spnego-template.c +++ b/asn1/spnego/packet-spnego-template.c @@ -1026,13 +1026,30 @@ dissect_spnego_krb5_cfx_wrap_base(tvbuff_t *tvb, int off if (pinfo->gssapi_data_encrypted) { checksum_size = 44 + ec; + + proto_tree_add_item(tree, hf_spnego_krb5_sgn_cksum, tvb, offset, + checksum_size, ENC_NA); + offset += checksum_size; + } else { - checksum_size = 12; - } + tvbuff_t *inner_token; + int inner_token_len = 0; + heur_dtbl_entry_t *hdtbl_entry; - proto_tree_add_item(tree, hf_spnego_krb5_sgn_cksum, tvb, offset, - checksum_size, ENC_NA); - offset += checksum_size; + checksum_size = ec; + + inner_token_len = tvb_reported_length_remaining(tvb, offset) - + ec; + inner_token = tvb_new_subset(tvb, offset, inner_token_len, + tvb_reported_length(tvb)); + + call_some_dissector(inner_token, pinfo, tree, FALSE); + + offset += inner_token_len; + + proto_tree_add_item(tree, hf_spnego_krb5_sgn_cksum, tvb, offset, + checksum_size, ENC_NA); + } if(pinfo->decrypt_gssapi_tvb){ /* if the caller did not provide a tvb, then we just use So, how do I call the next dissector? The only clue I have so far is that the inner token looks like it is ASN.1 encoded because it starts with 0x3073... Any clues out there? -- Regards, Richard Sharpe (何以解憂?唯有杜康。--曹操) ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
