Protocol info column not set correctly in the Windows version

[darki2002]

Windows does not show the description in the info column wich is set in every payload type file

[darki2002]

• Windows shows the correct data in the info column if set in the packet-doip
• Windows also reaches the line in the payload type file when the payload is dissected (proved by adding a console printf before this line)

[darki2002]

• Windows can also resolve the description string (printf debug)
• Windows does not set the column correctly in the payload type file (proven by setting a fixed "Hello World" string there)

I was able to show the Info column once, but it is unreproduceable why... (I used some printfs and then col_add_str in 0005. But wireshark crashed when searching for doip or payload types... but when scrolling arround I was able to see doip packages with correct info column set... :/)

• maybe there is something wrong with the col_set_str function and we should use col_add_str instead because it makes a copy of the variable and is visable all the time. But I could not handle to use this sucessfully.

I got an violation error when reading the cinfo, so I try to check weather this function is really writeable in the dissector file

[darki2002]

I am on a working state now, but cannot state why it is working. This is the part of the payload-0005.c:

`void dissect_payload_0005(doip_header header, proto_item pitem, packet_info pinfo)
{ tvbuff_t tvb; proto_tree *doip_tree;

/* set info column to description */
printf("HELLO WEORLD\n");
printf(description);
printf("\n");
printf(col_get_text(pinfo->cinfo, COL_INFO));
if(col_get_writable(pinfo->cinfo)) {
    printf("\n this is writeable! \n");
}

col_clear(pinfo->cinfo, COL_INFO);
col_add_str(pinfo->cinfo, COL_INFO, description); .....`

The wireshark console output now is (as picture, because I cannot copy from wireshark console):

• It is pretty strange, but now, all payload types are working.... so there is something wrong with the build process or something other
• whey trying to search for doip or payload type -> CRASH
• I will try to adjust the example

[darki2002]

After removing the debug output: `...

/* set info column to description */
/*printf("HELLO WEORLD\n");
printf(description);
printf("\n");
printf(col_get_text(pinfo->cinfo, COL_INFO));
if(col_get_writable(pinfo->cinfo)) {
    printf("\n this is writeable! \n");
}
*/
col_clear(pinfo->cinfo, COL_INFO);
col_add_str(pinfo->cinfo, COL_INFO, description);

...` I can now open wireshark again and get the write info column. I can now also search for doip or doip.payload.type == ... but whey I do a searching, the info column sets itself back to Ack-=..., Len=... etc.

The Error does NOT occure when using the wireshark-gtk.exe!

I will further check other wireshark versions (2.0.4 and 1.12.12).

[darki2002]

Same happens with Wireshark 2.0.4 The correspongin TCP Info column is shown in the info Column.
