|
* extremely threadbare null-pointer protectionKartik K. Agaram2021-04-281-0/+6
| | | | | | | | | | | | | This protects us from reading null arrays, but not null structs. It also doesn't protect us from writes to address 0 itself. It is also incredibly unsafe. According to https://wiki.osdev.org/Memory_Map_(x86), address 0 contains the real-mode IVT. Am I sure it'll never ever get used after I switch to protected mode? I really need a page table, something minimal to protect the first 4KB of physical memory or something. I wonder what other languages/OSs do to protect against really large struct definitions.
* bugfix: initialize gap buffers before using themKartik K. Agaram2021-04-282-2/+5
| | | | | | | I keep running into one hole in Mu's memory-safety since dropping the Linux dependency: null pointers no longer error when dereferenced. Here the problem manifests as aliasing: lots of gap buffers share the same exact data near address 0, because it was never initialized.

* shell: load/store from/to disk with indentKartik K. Agaram2021-04-282-25/+82
| | | | | Once I came up with the right approach, this worked on the first try once I got the types and registers to line up!
