This PR updates the ReflectiveDLLInjection:
DoSyscalland theSyscallStubto use a new formatSyscallStubfunction calls to use the new formatWhy
Current implementation of the direct syscall fails on the DoSyscall function, most likely due to compiler-specific assumptions for example like the previous stack frame location
dll/src/GateTrampoline64.s:12.This PR updates the way we trigger the syscall, going from a parameters passthrough function to an array-to-parameters type of function.
The
DoSyscallnow receive aULONG_PTR **array of args, used to store the parameters. Then the function is responsible to setup the stack arguments properly, and setup the remaining arguments to registers. and perform the call to thesyscallinstruction location after honoring the the syscall-number setup on eax and movingrcx to r10.
