Hello guys,

 

I’m having a weird problem with the fragment_add_seq_check function.

I have a DLL plugin where I handle fragmentation.

The same DLL, which works with Wireshark 1.8.6:

frag=1, patch_seq=0, msg_id=3608, frag_remaining=33, frag_msg=059FF780

fails in Wireshark 1.8.8:

frag=1, patch_seq=0, msg_id=3608, frag_remaining=33, frag_msg=00000000

 

below is the function call I use (params are corresponding to the text above):

frag_msg = fragment_add_seq_check(tvb,offset,pinfo,msg_id,

                           my_fragment_table,

                           my_reassembled_table,

                           patch_seq,

                           frag_remaining, (frag != FR_LAST));

 

I checked several wireshark versions, older and newer (including latest 1.10 trunk) and for some reason I can only make it work with 1.8.6.

did anyone ever had this problem? Or know what might cause this issue?

I’m lost.

 

Thanks,

Maayan
