Hi,
I am developing a dissector for MPICH over TCP and trying to use
tcp_dissect_pdus. But unfortunately I am getting a blank screen. My
code
looks like this:
void
dissect_mpich_tcp_nonepm (tvbuff_t * tvb, packet_info * pinfo,
proto_tree
* tree)
{
tcp_dissect_pdus (tvb, pinfo, tree, mpich_desegment, HEADER_LENGTH,
get_mpich_pdu_len, dissect_mpich_tcp_nonepm_pdu);
}
guint
get_mpich_pdu_len (tvbuff_t * tvb, int offset)
{
guint32 messageSize = 0;
guint32 messagetype = 0;
messagetype = tvb_get_ntohs(tvb, offset);
if (messagetype == MPIDI_CH3_PKT_EAGER_SEND)
messageSize = tvb_get_ntohs(tvb,offset + 12);
return messageSize;
}
I noticed my code enter get_mpich_pdu_len but never goes beyond
messagetype = tvb_get_ntohs(tvb, offset); line.
I am not sure what I am doing wrong.
Any help is fully appreciated.
Seyed.
