Re: War2 100% of 1 core CPU load - CPU Savior, version 2

Let me share the source code for this project.
Looks like I adandoned that project, maybe somebody will fix crashes for win8-10 also...
Maybe i will some day, but not sure if i have enough time or not.

This: https://bitbucket.org/ilwar2/war2-cpu-savior

Let me know if something wrong: my first git repository :)

If people have a Win8/10 system, there is less of a possibility that they might need it (powerful enough system)!
I actually don't mean it 100% works on win-non 8/10 and doesn't work on others. That just caused crash on my test win8/10 platforms and didn't on winxp/vista/7. Maybe that was just my luck/unluck.

Did you try version 2 (cpusavior_cmd) or version 1 (cpusavior_il)?
Did it work stable for you?

I just got an idea that address GETPROP_ADDR 0x150452A4 is not the same for every system.
Hm, or depends on x86 or x64 os? Which OS do you have?

the dll can be rebased but the exe can not, so the trick is to pull the dll address from the exe IAT.

any reason to avoid patching in-place?

this untested example code makes my eyes bleed less  :'(
Code: [Select]
void CpuSaver_Hook_Storm208( HANDLE hProcess ){
DWORD dwPrevProtect;
DWORD storm208_va;
DWORD offset = 0x15011370 - 0x150112E0;
BYTE data[] = { 0x89, 0xE8, 0x83, 0xE8, 0x3C, 0x6A, 0x01, 0xFF, 0xD0, 0xEB, 0xE2, 0x90 };
ReadProcessMemory( hProcess, (void*)0x004902C8, storm208_va, 4, 0 );
VirtualProtectEx(  hProcess, storm208_va + offset, sizeof(data), PAGE_EXECUTE_READWRITE, &dwPrevProtect );
WriteProcessMemory( hProcess, storm208_va + offset, data, sizeof(data), 0 );
VirtualProtectEx( hProcess, storm208_va + offset, sizeof(data), dwPrevProtect, &dwPrevProtect );
}

Well, i just copied the idea from R!CH project, similar solution :P

aqrit, your idea looks much better!
I just didn't understand how you understood that storm208 is what we need.

I opened storm.dll in IDA and looked into 15011378 (address after: call    ebx ; GetPropA)
It belongs function called Ordinal208 - is that a key? Ordinal208 == storm208?


I also didn't understand your trick with asm code on 15011370:
why EBP-3C is address of Sleep?

Sorry for stupid questions, i never had experience with dll addressing before...

Ordinal208 == storm208
yeah, IDA just makes up a name for it because it is un-named...
in the "Exports" tab... double-clicking "Storm_208" jumps to "Ordinal208"

This can be checked by looking at it in a debugger,
checking the IAT structure by hand, or using some other tool.

That is a typo, EBX is the pointer to GetPropA (not EBP)
which would make the first two bytes of data "89 D8" ( not "89 E8" )

ebx == GetPropA == 0x15033270
Sleep == 0x15033234
0x15033270 - 0x15033234 = 0x3C

Thx, just have not been sure that 208 is a constant between exe and dll.
I wasn't able to load both exe and dll into the same IDA instance, so i used if separately (my bad knowledge in IDA).

That is a typo, EBX is the pointer to GetPropA (not EBP)
which would make the first two bytes of data "89 D8" ( not "89 E8" )
I see, just a mistake.
Also i didn't think distance between GetPropA and Sleep is constant in all the systems, past and future. Can it be hardcoded as 3C?

Anyways, i like you idea to find storm208 by address and then to patch it some way. Should 100% work on any system.

yeah that is NOT going to work :)
I shouldn't post things without trying them I suppose...

I was thinking it was mov ebx, xxxxx
when it was actually mov ebx, [xxxxx]

I see, as you wrote it's just an untested example, thx for it.
You idea with patching in-place is good, you right, i should never use hardcoded 0x15XXXXXX addresses and i can safely use 0x004XXXXX anywhere. I'll try to modify my project...

Oh cool.   :)

Somehow missed this thread last year. Must have been busy having a mental breakdown at the time...

Anyway, this is totally the way to go. You can never reliably hard code procedure entry points in external modules. They can be re-mapped by the OS, but in fact almost never are. The other problem is different versions of the same module will shift the entry points for the individual procedures even if the module is mapped at the same base address.

In theory modules can be re-mapped by the OS and they will be in the case where multiple 3rd party modules attempt to use the same address space, but AFAIK for core API modules the only time M$ seriously tried to impliment this was for Vista. It was supposed to be a security feature but ended up being a Pandora's Box of cascading bugs that eventually imploded the whole OS.

But as aqrit points out, the only way to go when linking procedure calls is to use the correct import/export structures. You can always get these from the IMAGE_EXPORT_DIRECTORY but if the proc you want is already imported by the target application, then its much easier to just us the Import Address Table, as the system loader will have already done the work for you.

In the case of WC2 it already imports a fairly decent list of handy API functions, but most notably it imports both LoadLibrary and GetProcAddress. Obviously when you have access to there 2 functions you can always import anything you want to.

the "call DWORD ptr[IAT offset]" method is ideal for injected code. When doing this type of thing I find it handy to to just define the proc names as equates then you only need to add the square brackets to call instructions. i.e.

Code: [Select]
Sleep            equ  490168h

.code

push 50
call [Sleep]

If you keep your equates in a seperate include, you can swap them in/out in exchange for standard API includes which helps when testing/compiling for injection.

So how did this end up going? I tested it on my system and it seemed to work well in-game, but not in the chat channel. Did this ever end up being fixed?

Re: Re: War2 100% of 1 core CPU load - CPU Savior, version 2

Anyway, this is totally the way to go. You can never reliably hard code procedure entry points in external modules. They can be re-mapped by the OS, but in fact almost never are. The other problem is different versions of the same module will shift the entry points for the individual procedures even if the module is mapped at the same base address.
I'd appreciate if you fork my project, fix that and release it as your version somewhere on bitbucket.org or anywhere else. That is my first experince with hooking and it's not perfect. I'd be glad to look into that myself and understand how to fix it, but i absolutely have no time for war2 and for such low-priority projects.
If you fix my code i can build it and distrubute to community and a part of combat or w/e (after some beta-test period to make sure everything works perfect everywhere).
Need help to translate War2Combat to German, French, Italian, Polish or another language: http://forum.war2.ru/index.php/topic,4728.0.html
Please, contact me if you are interested in that.
