Hi,
Can anybody help me with packet reassembly?
I've been working with Wireshark 1.8 'til now and the same scenario worked
there just fine.
I'm trying to move into 1.10.7 and reworking the code so it will perform the
same dissection.
In the block bellow fragment_add_seq_check keeps returning NULL into frag_msg
so obvious process_reassembled_data returns NULL as well.
frag_msg = fragment_add_seq_check(&my_fragment_table,
tvb,offset,pinfo,
msg_id,
NULL,
patch_seq,
frag_remaining,
(frag_type != FR_LAST));
new_tvb = process_reassembled_data(tvb,offset,pinfo,
"Reassembled Message ",
frag_msg,
&my_frag_items,
NULL,tree);
In an header file I declared:
static reassembly_table my_fragment_table;
static const fragment_items my_frag_items = {
/* Fragment subtrees */
&ett_msg_fragment,
&ett_msg_fragments,
/* Fragment fields */
&hf_msg_fragments,
&hf_msg_fragment,
&hf_msg_fragment_overlap,
&hf_msg_fragment_overlap_conflicts,
&hf_msg_fragment_multiple_tails,
&hf_msg_fragment_too_long_fragment,
&hf_msg_fragment_error,
&hf_msg_fragment_count,
/* Reassembled in field */
&hf_msg_reassembled_in,
/* Reassembled length field */
&hf_msg_reassembled_length,
&hf_msg_reassembled_data,
/* Tag */
"Message fragments"
};
Where my_fragment_table was initialized by:
reassembly_table_init(&my_fragment_table,&addresses_reassembly_table_functions);
can anyone tell me what I'm doing wrong?
Thanks,
Maayan
