Wireshark's SIP dissector is throwing an error on the RAck header field method name. It shouldn't, because the message's header is correctly formed, but there's a bug in packet-sip.c: for case POS_RACK, when it goes to add the method name, it's using '(int)linelen-sub_value_offset' for the length argument to proto_tree_add_item(), but should be using '(int)value_len-sub_value_offset'. patch: Index: epan/dissectors/packet-sip.c =================================================================== --- epan/dissectors/packet-sip.c (revision 47899) +++ epan/dissectors/packet-sip.c (working copy) @@ -2734,7 +2734,7 @@ { proto_tree_add_item(rack_tree, hf_sip_rack_cseq_method, tvb, value_offset + sub_value_offset, - (int)linelen-sub_value_offset, ENC_ASCII|ENC_NA); + (int)value_len-sub_value_offset, ENC_ASCII|ENC_NA); } break; -hadriel On Feb 28, 2013, at 1:21 AM, Lohith HS <lohith.hs () globaledgesoft com> wrote:
