DispatchCode

When a user-space application accesses a virtual memory address, that address belongs to the address space of the corresponding process. Each user-space task has its own address space: the translation from a virtual address to a physical address starts from the CR3 value. Using this syscall, it is possible to read the memory of another running task.

This is intended for educational purposes only, so the code is by no means production-ready. It could also be interesting to add a syscall and walk the address space :)

Add a new syscall

I created a new folder called memory. This is where the source code will be placed. Kbuild also needs to be updated by adding the following line:

How to use:

./wordle.sh

Or try the unlimit mode:

@echo off
setlocal ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION

::this also support calls that contains a absolute windows path

::check of one of the params contain a absolute windows path

if %errorlevel% == 1 (
    ::if not just git with the given parameters
    call :git %*

[UPDATE] Sublime Text 4

If you have the latest sublime text (version 4), you can just do:

subl --safe-mode

How do I revert Sublime Text 3 to a fresh state

The apt-get version of node is incredibly old, and installing a new copy is a bit of a runaround.

So here's how you can use NVM to quickly get a fresh copy of Node on your new Bash on Windows install

$ touch ~/.bashrc
$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
// restart bash
$ nvm install --lts

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git

By the way, I'm available for tutoring and code review :)
