t3hn3rd d0425a41e3 feature: WASM execution pipeline, file dispatch, RAM drive, and VFS handle table
- Add file-type dispatch registry (filedispatch.pas) matching files by
  magic header bytes and routing to registered handlers
- Add WASM integration layer: wasmshim, wasmio, wasmrunner, wasmcleanup
  providing full WASI Preview1 bridging (fd_write/read, proc_exit,
  clock, random, args passthrough, environ stubs)
- Add RAM drive (ramdrive.pas) providing in-memory VFS at /disk/ram
  with a built-in hello world WASM binary
- (Placeholder) Implement VFS handle table for proper
  open/read/write/close/filesize routing through registered drives
  and devices
- Integrate file dispatch into vterminal for unknown commands, supporting
  both foreground and background execution of dispatched files
- Expand progmanager init with PS, KILL, TERMINATE, DEV, DISK, MEMRAW,
  BSOD, IFCONFIG, ARP, and TCP commands; wire up ramdrive, filedispatch,
  and wasmrunner initialization
- Replace serial.sendString with syslog.logln in desktop launcher

t3hn3rd 463b746b82 fix: drone pipeline not working
continuous-integration/drone/push Build is passing
- compile_wasuro.sh was copying files to the /code directory which
  is not where drone builds from, fixed to use $(pwd) and relative
  directories based on the root.

t3hn3rd 8b4335768b refactor(memory): complete PMM/VMM/LMM rewrite - bitmap allocators, bug fixes, hardening
continuous-integration/drone/push Build is passing
continuous-integration/drone/pr Build is passing
PMM Rewrite:
- Replace ~8KB record array with compact bitmaps
  (PhysPresent/PhysAlloc/PhysScanned, 128B each)
- Add PhysOwner[0..1023] for per-block ownership tracking
- new_block: O(1) amortised via NextFreeHint + dword-level BSF scan,
  returns 0 as OOM sentinel
- free_block: O(1) direct bit clear with double-free detection
- alloc_block: validates PhysPresent and PhysAlloc bits before allocation
- Add pmm_free_blocks/pmm_total_blocks stats functions

VMM Correctness Fixes:
- Fix free_page block extraction (Address SHR 10, was using
  raw Address field)
- Fix invlpg operand (use virtual address, was passing PDE index)
- Clear PDE entry on free_page before returning block to PMM
- Remove map_page double-write (delegate to map_page_ex only)
- Add OOM propagation (new_page returns false if PMM returns 0)
- Fix missing pop_trace in new_page error path

LMM Rewrite:
- Replace per-entry record array with bitmap allocator
  (93% vs 43% page efficiency)
- Layout: Header(24B) + Bitmap(64512B) + Padding + Data at 0x10000
- SIZE_PREFIX=16 for 16-byte aligned returns (SSE MOVAPS requirement)
- Next-fit bitmap scan with roving hint (NextFree) and dword-level
  fast skip
- Large alloc sentinel (LARGE_ALLOC_MAGIC=$FFFFFFFE) so kfree detects
  klalloc'd memory
- Implement klfree (was previously a no-op - pages could never
  be returned)
- Implement try_release_page (return fully-free heap pages to VMM/PMM)
- Fix interrupt safety: stack-balanced pushfd/cli/pop +
  restore_if (sti only)
  Fixes Bad TSS caused by popfd restoring dangerous EFLAGS bits (NT, IOPL)
- Zero memory via rep stosd instead of byte-by-byte loop

Hardening:
- kalloc OOM now triggers BSOD instead of returning nil
  (90% of callers don't check)
- Double-free detection in kfree (verify bitmap bits set before clearing)
- Guard bytes ({$IFDEF DEBUG_LMM}): $DEADBEEF sentinel for buffer overrun detection
- kpalloc: bounds check (block >= 1024 -> GPF) + syslog MMIO mapping audit log

Observability:
- Add MEMINFO command as src/prog/meminfo.pas (moved from inline kernel.pas)
- Displays multiboot memory, PMM block stats, LMM heap stats
- Register via progmanager.pas following standard prog pattern

Files changed:
- src/pmemorymanager.pas
- src/vmemorymanager.pas
- src/lmemorymanager.pas
- src/kernel.pas
- src/progmanager.pas
- src/prog/meminfo.pas

t3hn3rd 91cd005361 feat: integrate Wasuro WASM runtime into Asuro build chain
continuous-integration/drone/push Build is failing
- Add compile_wasuro.sh to sparse-clone Wasuro src/wasm from gitea
  (develop branch) with caching to skip redundant pulls
- Update compile.sh to include wasuro build step in pipeline
- Update compile_sources.sh to dynamically discover -Fu paths via
  find across src/ and wasuro/ directories
- Extend system.pas with FPC 3.2.2 compilerprocs required by Wasuro:
  - 64-bit signed/unsigned div and mod (fpc_div_int64, fpc_mod_int64,
    fpc_div_qword, fpc_mod_qword) with correct i386 parameter mapping
  - 64-bit multiply (fpc_mul_int64) via three 32-bit MUL instructions
  - Float-to-integer intrinsics (Trunc, Round) using x87 FPU
  - Memory allocation compilerprocs (fpc_getmem, fpc_freemem)
    delegating to kernel kalloc/kfree
  - Exception handling stubs (reraise, raiseexception, catches, doneexception)
  - setjmp/longjmp for exception address stack
  - Fix sInt64 type alias (was longint/32-bit, now int64/64-bit)
  - Add serial debug helpers (COM1 $3F8) for bare-metal tracing
- Wire up Wasuro in kernel.pas: init WASM VM, set I/O callback to
  syslog, and run all 1103 Wasuro tests (0 failures)
- Update .gitignore to exclude wasuro/ cache directory

t3hn3rd 99fd5507ca Merge branch 'feature/vtop-fix' into feature/process-management
continuous-integration/drone/push Build is passing
2026-03-03 19:11:47 +00:00
t3hn3rd 035d489c4f feature: preemptive process management - implementation progress
continuous-integration/drone/push Build is passing
Implement a preemptive multitasking system for the Asuro kernel.

Context Switching & Scheduling:
- Custom IRQ0 ISR (contextswitcher.pas) with PUSHAD/POPAD ESP-swap
- Round-robin scheduler with priority-based quantum
- Process table using DList of PProcessContext pointers
- Idle process (PID 0) replaces kernel HLT loop

Process Lifecycle:
- create/kill/terminate/sendMessage API (processmanager.pas)
- Process states: Created, Running, Ready, Suspended, Awaiting,
  Finished, Error
- Parent-child tracking (ParentID, smChildExited notification on reap)
- proc_yield, proc_sleep_ms, proc_await, proc_suspend, proc_exit

Resource Binding & Cleanup:
- Per-process resource list
  (bindResource/unbindResource/unbindAllResources)
- TCP sockets auto-bound to owning process (OwnerPID on TTCPSocket)
- socket_cleanup + auto-unbind in DestroySocket

VTerminal Refactor:
- Multi-instance design (heap-allocated TVTermState per terminal)
- Foreground process with incremental stdout/stderr drain via LVGL timer
- Ctrl+C kills foreground process (killForeground)
- Per-terminal CWD, dir stack, FS builtins (CD/LS/PUSHD/POPD)
- Background job support (& suffix, JOBS/FG commands)
- Command history (Up/Down arrow)

Command Consolidation:
- 14 commands extracted from 9 units into centralized progmanager.pas
- Command procedures exported in host unit interfaces
- E1000/TRACER/stdio builtins kept in-place (conditional/circular)

New Units:
- src/include/proctypes.pas — process type definitions
- src/processmanager.pas — core process manager
- src/prog/ping.pas — standalone ICMP ping process
- src/prog/testcmd.pas — test command (proc_sleep_ms demo)
- src/testprocs.pas — process subsystem smoke tests

Misc:
- ICMP callbacks gain userData parameter for concurrency-safe ping
- CLI/STI guards on kalloc/kfree (lmemorymanager.pas)
- LV_KEY_CTRLC constant + Ctrl+C interception in LVGL keyboard hook
- Window owner PID tracking (windows.pas)
- ISR_32 gate override support (isrmanager.pas)

t3hn3rd 5e9d0004d7 feature: implement TCP (RFC 793) protocol driver
continuous-integration/drone/push Build is passing
Add full TCP/IP stack implementation at L4 alongside UDP and ICMP.

Core Protocol Engine:
- TCP types in nettypes.pas (header, TCB, state enum, error codes,
  callbacks, OOO entry, socket structures)
- 3-way handshake (active & passive OPEN)
- Reliable data transfer with ACK and sequence number tracking
- Graceful close (FIN_WAIT, CLOSE_WAIT, LAST_ACK, TIME_WAIT)
- RST send/receive handling
- Retransmission with exponential backoff (max 5 attempts)
- Pseudo-header based checksum (RFC 793)

Server Support:
- LISTEN → SYN_RECEIVED → ESTABLISHED passive open path
- Listen backlog enforcement (configurable per-socket)
- accept() to retrieve established child connections

Robustness & Hardening:
- Delayed ACK timer (~200ms)
- Nagle's algorithm (buffer small sends while unACKed data pending)
- Jacobson/Karels RTT estimation with adaptive RTO
- Congestion control (slow start / congestion avoidance)
- Zero-window probing with exponential backoff
- MSS option negotiation in SYN/SYN-ACK (Kind=2, Len=4)
- Keep-alive (30s idle, 10s interval, 5 probes)
- Out-of-order segment reassembly (4-slot buffer)

Terminal & Testing:
- tcpconnect: active open + send "Hello, World!"
- tcplisten: passive open with syslog output
- tcphttp: HTTP/1.0 GET client

Also add push_trace() instrumentation to net, eth2, arp, ipv4,
icmp, udp, and dhcp entry points for call tracing, and register
tcp in net.init.
