[4.0.0 12025] Opcode ID changed ?

[Woweur]

Hey, i have patched my cataclysm alpha to the next build (12025) and i have try to adapt emulator for this. Ok, so i have decompile with IDA in pseudo-code wow.exe ...etc.

When i try to find the new offset for ReadUint32, HandleOpcode i have find that :

//----- (004BC690) --------------------------------------------------------
void __cdecl sub_4BC690()
{
  void *v0; // eax@2

  if ( !dword_C1C980 )
  {
    v0 = sub_7A6F40(57752, (int)".\\FriendList.cpp", 1207, 0);
    if ( v0 )
      dword_C1C980 = sub_4B68E0(v0);
    else
      dword_C1C980 = 0;
    sub_4B3B80(0x2FEDu, (int)sub_4BC370, 0);
    sub_4B3B80(0x3B68u, (int)sub_4B69D0, 0);
    sub_4B3B80(0xCBEBu, (int)sub_4B6A10, 0);
    sub_4B3B80(0xBFECu, (int)sub_4BC350, 0);
    sub_4B3B80(0x7FECu, (int)sub_4BC300, 0);
    sub_5F9E60((int)"whois", (int)sub_4B78F0, 0, (int)"Ask the server to do an account/real name lookup on a character name");

Ok, so sub_4B3B80 is a function for handle recv opcode from the server, so the first argument of the function is opcode id !

Here you can view the same function for build 11927 :

//----- (00FriendList__Initialize) --------------------------------------------------------
void __cdecl sub_FriendList__Initialize()
{
  void *v0; // eax@2

  if ( !dword_B8E3E0 )
  {
    v0 = sub_SMemAlloc(57752, (signed int)".\\FriendList.cpp", 1207, 0);
    if ( v0 )
      dword_B8E3E0 = sub_FriendList__FriendList(v0);
    else
      dword_B8E3E0 = 0;
    sub_ClientServices_SetMessageHandler(99, (int)sub_Packet_Packet_SMSG_WHO, 0);
    sub_ClientServices_SetMessageHandler(101, (int)sub_Packet_Packet_SMSG_WHOIS, 0);
    sub_ClientServices_SetMessageHandler(510, (int)sub_Packet_Packet_SMSG_RWHOIS, 0);
    sub_ClientServices_SetMessageHandler(103, (int)sub_Packet_Packet_SMSG_CONTACT_LIST, 0);
    sub_ClientServices_SetMessageHandler(104, (int)sub_Packet_Packet_SMSG_FRIEND_STATUS, 0);
    sub_ConsoleCommandRegister("whois", (int)sub_4B1890, 0, (int)"Ask the server to do an account/real name lookup on a character name");

so, WTF ? Blizzard has change all opcode id ?

[TOM_RUS]

Yeah. Looks like they randomized all opcodes

[Woweur]

Ok so i'm no crasy =P.
I don't think it's random opcode id, maybe formule, flags or something.

[XTZGZoReX]

All research so far shows that they're completely randomized during compile-time.

The randomized IDs are "condensed" though, but it's seemingly not anything that'd be useful to us.

So until someone works their magic, we're pretty much ****ed.

[Woweur]

I Try to make a little tool for convert old server's opcode to new server's opcode, i just need go into a game with new build. Noby has a sandbox source ? (because with sandbox, we havn't a lot of opcode to change manualy =P).

[Hiperzone]

lol anyone having trouble locating SMSG_AUTH_CHALLENGE and SMSG_COMPRESSED_OBJECT opcodes? cant seem to find the ids at all.

[XTZGZoReX]

lol anyone having trouble locating SMSG_AUTH_CHALLENGE and SMSG_COMPRESSED_OBJECT opcodes? cant seem to find the ids at all.

I hope you're not searching for their old, non-randomized value...

I Try to make a little tool for convert old server's opcode to new server's opcode, i just need go into a game with new build. Noby has a sandbox source ? (because with sandbox, we havn't a lot of opcode to change manualy =P).

How would you even achieve that?

[Woweur]

45027 is a new randomized ID for smsg_compress_object_update and 7651 is a new randomized ID for SMSG_AUTH_CHALLENGE.

[Hiperzone]

ye i found the challenge one by myself, thx for the other. im able to reach char enum now, just need to get CMSG_CHAR_LOGIN for world enter.

[Woweur]

it's 35820 for CMSG_CHAR_LOGIN.

[Hurrr]

Here's a (long and painful) way to find the new values for all the SMSG opcodes.

Run two instances of IDA pro side-by-side, one with the 11927 client and one with the 12025 client.

In the old client, the function located at 4AE1A0 registers a handler function for a given SMSG opcode. You can find all references to it, it's called with the opcode as first parameter (so pushed last before the call).

In the new client, that function is at 4B3B80 and works the exact same way, except with the randomized value for that opcode.

So in both IDA, go to that function and open the xref pane (view -> open subview -> cross references). Dock it to the side.

Now the nice thing is that the calls to those functions appears to be mostly in the same order in both versions of the client (ie the code looks the same in both place except for the opcode. I also looked at the handler code for a couple opcodes that were registered in the same place and the handler code seemed to match too).

So by going through each call one by one on each side you can establish a correspondence table between the old opcode values and the new ones.

I guess some script could be made to parse the disassembled code for both client and automatically build that correspondence table, the problem is that so far from what I seen the order can differ slightly, I've seen one small function registering just one opcode in the old client that wasn't there at the same place in the new one.

But to fish out individual opcodes I guess it's workable. I had started to collect all the opcodes manually but it's an awful lot of work to do by hand and it's error prone.

[Woweur]

Yeah, i have already done a little script for that (detour a function with injected DLL) but that work only if you can go in game AND it's work only for server opcode (SMSG).

[Hurrr]

I found the function that sends a CMSG. It's at 798080 in the new client and at 758790 in the 11927 client. It takes the opcode as first parameter on the stack. The same method as with the function that registers the SMSG handlers can probably be applied.

Gonna try to see if I can get mangos to work.

[Robske]

The ones I checked (mainly those related to movement) are correct.

Is this Blizzard's response to those 'teleport' hacks?...
