On offsets

After the recent release of ps5-kstuff with support for PS4 fpkg files, there is a lot of questions about porting this to other firmwares (4.50 and 4.51 are important in particular, because users of those firmwares can't update to 4.03, but they are still vulnerable to all of the used exploits). The main problem with these ports it the bespoke XOM, which prevents finding the offsets by simply examining the dumps. So in this document I'm going to go over what offsets are important for ps5-kstuff, and how I found them for 4.03.

These are the main categories of offsets:

  1. Kernel data offsets, those can be found from data dumps that are not XOM-protected
  2. Kernel text offsets pointed to by kernel data
  3. doreti_iret offset (that's one offset, but it deserves its own word)
  4. Offsets found from single-stepping of kernel functions

Rust modules and how to use them

So, how tf do rust modules work? and why tf are they not doing what I want right now???

Note: A bunch of things in here are defined by cargo and a few others by rust. I won't generally care about that distinction because two languages without standard build system is more than enough for my sanity.

➡️ Feel free to ask me on twitter if you have questions or remarks.

Ubuntu 21.04 VM with GPU acceleration under Hyper-V...?

Ubuntu 21.04 VM with GPU acceleration under Hyper-V...?

Modern versions of Windows support GPU paravirtualization in Hyper-V with normal consumer graphics cards. This is used e.g. for graphics acceleration in Windows Sandbox, as well as WSLg. In some cases, it may be useful to create a normal VM with GPU acceleration using this feature, but this is not officially supported. People already figured out how to do it with Windows guests though, so why not do the same with Linux? It should be easy given that WSLg is open source and reasonably well documented, right?

Well... not quite. I managed to get it to run... but not well.

How to do it?

  1. Verify driver support

Exploring function calls in Roc

This is a systematic in-depth exploration of different ways of calling functions in Roc.

Lambda expressions and function calls

In Roc, functions are values that are defined using lambda-expressions. Here are two single-argument functions on integers, one that increments a given number and another that doubles it.
