#FreeBSD, a Unix-like operating system, is often shrouded in myths and misconceptions. Originating from the Berkeley Software Distribution (hence BSD), #FreeBSD is renowned for its reliability, performance, and advanced networking features. However, several myths have arisen over the years, clouding the true capabilities and characteristics of this OS. In this article, we aim to debunk these myths and shed light on what FreeBSD truly offers. https://lnkd.in/e7Zea2Q9

[FreeBSD Commit] Disable KASAN for generated symbols. In a recent commit we focused on fixing a bug where KASAN inserting guards around global variables causing incorrect offsets within the kernel. Kernel Address Sanitizer (KASAN) detects use-after-free, out of bounds, and other memory errors that can leave to bugs and vulnerabilities. Harmful to performance, but invaluable during development https://lnkd.in/gTs7fYCq
