Michał Sapka ☛ Docker free since 2024
As of today, my entire infrastructure is migrated. I no longer need to care about Docker dancing for VC’s moneys - at least personally; at work I am still forced to use it… and a Mac. Some services will follow soon (like Jellyfin), as I want them to behave differently but today I have stopped the last Docker container.

Trail of Bits ☛ A deep dive into Linux’s new mseal syscall
If you love exploit mitigations, you may have heard of a new system call named mseal landing into the Linux kernel’s 6.10 release, providing a protection called “memory sealing.” Beyond notes from the authors, very little information about this mitigation exists. In this blog post, we’ll explain what this syscall is, including how it’s different from prior memory protection schemes and how it works in the kernel to protect virtual memory. We’ll also describe the particular exploit scenarios that mseal helps stop in Linux userspace, such as stopping malicious permissions tampering and preventing memory unmapping attacks.
