https://polymathmonkey.github.io/weblog/artifacts/openbsdmalloc/index.htmlThe unseen hero of OpenBSD: otto’s malloc What this is about This is me learning about OpenBSD’s malloc. I try not to do a surface-level overview. I want to understand the internals better, the data structures, the design decisions, and why those decisions make heap exploitation so much harder. What malloc actually does Every C program that needs memory at runtime calls malloc. malloc is a library function. It’s not a syscall – it’s a layer between your code and the kernel.Hugoen-usAll text is licensed under a Creative Commons Attribution 4.0 International License.
