eth-ws-someip's Issues

Multiple PDUs

If there are multiple PDUs in a buffer, only the first is parsed. The rest are currently put in the "data" field.
I am writing some code to fix this

Lua Error: string expected, got nil

Getting the following error when I try to analyze someIP packets: 'Lua Error : PATH\someip.lua:129: bad argument #3 to '__newindex' (string expected, got nil)' . If needed I will uploaded a packet for analysis.

Error during loading in someip.lua:13: bad argument #1 to 'Proto' (Proto_new: there cannot be two protocols with the same name)

Hi,

I am using Wireshark 3.2.1 on Linux 5.4.0-kali3-amd64 and I was receiving this error during startup after following your installation instructions:

Lua: Error during loading:
.local/lib/wireshark/plugins/3.2/eth-ws-someip/someip.lua:13:
bad argument #1 to 'Proto' (Proto_new: there cannot be two protocols with the same name)
stack traceback:
[C]: in function 'Proto'
.local/lib/wireshark/plugins/3.2/eth-ws-someip/someip.lua:13: in main chunk

The fix was to replace line 13 in someip.lua with the following expression:

p_someip = Proto("someip2","Scalable service-Oriented MiddlewarE over IP")

Then during packet analysis, Wireshark was throwing an error in line 135 in sd_options.lua which was solved by the following fix:

if o_l4[l4_u8] == "TCP" then
    DissectorTable.get("tcp.port"):add(buf(offset,2):uint(),Dissector.get("someip2"))
elseif o_l4[l4_u8] == "UDP" then
    DissectorTable.get("udp.port"):add(buf(offset,2):uint(),Dissector.get("someip2"))
end

I cannot recall that I have installed a Wireshark SOME/IP plugin before. So I am a bit confused by the errors.

Cheers,
Arnd
