My research has led me to believe that limiting stack size is unfair to languages like Ada and Rust that prioritise security. Whilst there are a number of invalid reasons posted online for limiting it more than the heap. The real reason was limited virtual address space which is not an issue on 64-bit systems. The stack is also faster generally (the heap is useful for some data structures of course) and so discouraging it's use so heavily for programs without root seems sub optimal?
Even if the kernel probably shouldn't. There might be an issue of the kernel expecting it to be limited even though it probably shouldn't. Does anyone know if that is true? -- Regards, Kc
