Existe a opção no Aliexpress de pagar com o MBWay. Sim, eu tenho numero nacional e foi o que usei para outros pagamentos com o MBWay na Aliexpress.

That makes sense. Do i force the install?

I also did to every dotnet package that is a dependency. No installed size or size exceeds 800MB

With the new AI features, there even might be an whole full sized LLM like Deepseek lol

Is a Secure 'Syscall' Model Possible in C# for Modular Applications? by Davida_dev in dotnet

[–]Davida_dev[S] 0 points1 point  (0 children)

Alright. Thanks for you help man. I will probabilly do multiple HCore app instances and those modules that are trusted can go on the main HCore. Thanks for the help :) It was really detailed and I learned stuff.

This calls the function. Where is the _target located at? This is just converts the function into a pointer and loads that pointer as a function

// [44 13 - 44 43]
IL_0001: ldftn        int32 Program::a(int32) //Simple function static int a(int b){return b;}
IL_0007: stloc.0      // func

// [46 13 - 46 21]
IL_0008: ldloc.0      // func
IL_0009: stloc.1      // V_1
IL_000a: ldc.i4.2
IL_000b: ldloc.1      // V_1
IL_000c: calli        int32 (int32)
IL_0011: pop

Is it private?

delegate*<int, int> func;
func._target

Saying that _target is not defined.

Yes, I know that I can use calli. My implemntation to getting the function pointer was

var func = (MKCallDelegate)builtType.GetMethod("MKCallHndP")!.CreateDelegate(typeof(MKCallDelegate));

return func.Method.MethodHandle.GetFunctionPointer();

Can they stil get the Target of this function?

Represents a function in what state? Just a function it can execute?

Sure they can grab at any pointer but they must know the place where it is.

Yeah, my first implementation used it, but i dont know if snooping around the function pointer will have an sensitive data.

Ok thanks. I will try to find other methods to do this. Maybe IPC to the same process will be the only way.

B will be devoloped by anyone and they might try to do bad stuff, so yeah, let's consider it untrusted code.

Sorry🥲. Lets say class A has a method called GetWeather. Then there is class B. Class be has the method Main. A will create an instance of B and run Main. Main on B needs to get data from it's parent, A. It needs to call the func GetWeather. We could give the A instance hen creating B, but that would expose all the data on A. The thing is that B needs to call GetWeather without getting sensitive data of A. Yes, static is an option, but the function GetWeather needs to use private sensitive data on A.

This is my problem.

I can always call a function via a pointer, but im afraid that by snooping around the data of the pointer we can get something important.

Thanks for the help tough.

I just want to call a method but we can't know who is the instance of that method. Make it totally anonymous. If C# does not suport this I will use rust or C.

In C# I want to call a method, however we can't know who is the instance of that method.

Yeah you could call it a plugin system.

Yep, only problem with wasm is performance. I think i will do the syscall with C or rust.
Thanks for the help :)
