Koinos Kernel Module (Syscall Override)

[sgerbino]

As a blockchain developer, I would like to override system calls via in-band updates.

• [ ] Implement a upload_kernel_module operation, this operation should call the init function of the kernel module.
• [ ] Implement a system call register_syscall, ensuring the syscall table is only modified at the end of a block.
• [ ] Implement a system call unregister_syscall, ensuring the syscall table is only modified at the end of a block.

Register system call may look like this:

register_syscall( SYSCALL_PRINT, N("action") );

An example kernel module:

namespace koinos::kernel
{
   class module
   {
       void init() = 0;
   };
}

class my_module : public koinos::kernel::module
{
   void init()
   {
      register_syscall( SYSCALL_PRINT, N("print") );
   }

   [[koinos::action]]
   void print( std::string s )
   {
      _print( s );
   }
}

This design has been usurped. Closing.
