QEMU with VirtIO GPU Vulkan Support

With its latest reales qemu added the Venus patches so that virtio-gpu now support venus encapsulation for vulkan. This is one more piece to the puzzle towards full Vulkan support.

An outdated blog post on clollabora described in 2021 how to enable 3D acceleration of Vulkan applications in QEMU through the Venus experimental Vulkan driver for VirtIO-GPU with a local development environment. Following up on the outdated write up, this is how its done today.

Definitions

Let's start with the brief description of the projects mentioned in the post & extend them:

Deploy a Python WebSocket Server on Debian 10 ("buster") with `systemd` and `nginx`

Following are configuration files and instructions for using systemd to create Unix domain sockets to handle incoming websocket requests. Websocket requests are proxied by nginx.

While these instructions are for Debian 10, they should largely work on other Linux distributions. It may be necessary to change paths and the nginx username, which is www-data when installed with the Debian package manager.

Install requirements

user@host:~$ sudo apt update
user@host:~$ sudo apt install nginx python3 wget

Trying to deploy WPA3 on my home network

Introduction

Recently, news broke about a new possible offline attack on WPA2 using PMKID. To summarize the attack, WPA2 protected APs can end up broadcasting PMKID values which can then be used to offline-brute-force the password.

These PMKID values are computed this way:

PMKID = HMAC-SHA1-128(PMK, "PMK Name" | MAC_AP | MAC_STA)

README

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:
