I have made some changes to packet-giop.c that appear to work, but I don’t
quite understand why.
What I have done is added two new members to struct comp_req_list_entry..
address src; /* source address */
guint32 srcport; /* source port */
These I set by extending insert_in_comp_req_list
Then in get_mfn_from_fn_and_reqid I have extended the test
if (entry_ptr->reqid == reqid && cmp_address (&entry_ptr->src, addr) == 0
&& entry_ptr->srcport == pnum) { /* similar reqid */
return entry_ptr->fn; /* return MFN */
The bit I don’t understand is, to make this work the calls to
insert_in_comp_req_list require pinfo->src and pinfo->srcport and the call to
get_mfn_from_fn_and_reqid requires pinfo->src, pinfo->destport. This seems
wrong I would have thought the get call would require the destination address,
not the source.
The initial request stores the source IP & port. So I would have thought the
reply would have a destination IP & port to match, but it seems I have to use
the source IP and destination port.
Any idea what is going on?
Thanks for any help
