From 4cec2d8c252186e6349cc86c3b3669fca06b6c37 Mon Sep 17 00:00:00 2001 From: Markus Maiwald Date: Mon, 5 Jan 2026 01:14:24 +0100 Subject: [PATCH] feat(rumpk): Achieve interactive Mksh shell & formalize Sovereign FSH MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CHECKPOINT 7: Nuke LwIP, Fix Stack 🎯 PRIMARY ACHIEVEMENTS: - βœ… Interactive Mksh shell successfully boots and accepts input - βœ… Kernel-side LwIP networking disabled (moved to userland intent) - βœ… C-ABI handover fully operational (argc, argv, environ) - βœ… SPEC-130: Sovereign Filesystem Hierarchy formalized πŸ”§ KERNEL FIXES: 1. **Nuked Kernel LwIP** - Disabled membrane_init() in kernel.nim - Prevented automatic DHCP/IP acquisition - Network stack deferred to userland control 2. **Fixed C-ABI Stack Handover** - Updated rumpk_enter_userland signature: (entry, argc, argv, sp) - Kernel prepares userland stack at 0x8FFFFFE0 (top of user RAM) - Stack layout: [argc][argv[0]][argv[1]=NULL][envp[0]=NULL][string data] - Preserved kernel-passed arguments through subject_entry.S 3. **Fixed Trap Return Stack Switching** - Added sscratch swap before sret in entry_riscv.zig - Properly restores user stack and preserves kernel stack pointer - Fixes post-syscall instruction page fault 4. **Rebuilt Mksh with Fixed Runtime** - subject_entry.S no longer zeros a0/a1 - Arguments flow: Kernel -> switch.S -> subject_entry.S -> main() πŸ“ ARCHITECTURAL SPECS: - **SPEC-130: Sovereign Filesystem Hierarchy** - Tri-State (+1) Storage Model: /sysro, /etc, /run, /state - Declarative Stateless Doctrine (inspired by Clear Linux/Silverblue) - Ghost Writer Pattern: KDL recipes -> /etc generation - Bind-Mount Strategy for legacy app grafting - Database Contract for /state (transactional, encrypted) πŸ› οΈ DEVELOPER EXPERIENCE: - Fixed filesystem.nim to fallback to .nexus/ for local builds - Prevents permission errors during development πŸ§ͺ VERIFICATION: Syscalls confirmed working: write (0x200, 0x204), read (0x203) NEXT: Implement proper TTY/PTY subsystem for full job control Co-authored-by: --- apps/init/init.nim | 24 +- apps/subject_entry.S | 23 +-
