|
||||||
|
|
||||||
|
## Project Overview
|
||||||
|

## Component AGENTS.md Standard
|
||||||
|
|
||||||
|
Several sub-directories carry their own `AGENTS.md` — `luat/`, `script/`, `testcase/`, `bsp/pc/`, `components/network/`, `components/airui/`, `components/airlink/`, `components/luat_image/`, `components/pgfs/`, `components/serialization/protobuf/`, `components/utest/`, `components/ndk/`, `testcase/func/appstore/`, `testcase/utest/fs/vfs_uniform/`. Use the following rule to decide whether a new component needs one.
|
||||||
|
|
||||||
|
**Create a component-level `AGENTS.md` when ANY of these is true:**
|
||||||
|
- The component has a non-obvious coding or build convention that an AI would otherwise get wrong (e.g. `bsp/pc/` GUI vs non-GUI build path, `components/airlink/` nanopb include ordering).
|
||||||
|
- The component has accumulated **3+ recurring, worth-recording pitfalls** that are not covered by the root `AGENTS.md` (e.g. `components/serialization/protobuf/` ARM stack-slot debugging).
|
||||||
|
- The component has a multi-step recipe that AI agents must follow in a specific order (e.g. `components/ndk/` regression chain).
|
||||||
|
|
||||||
|
**Do NOT create a component-level `AGENTS.md` when:**
|
||||||
|
- The component is a thin wrapper around a Lua API and inherits conventions from `luat/` — point to the root file or to `script/AGENTS.md` instead.
|
||||||
|
- The content would just duplicate the root `AGENTS.md` Build & Test Commands section.
|
||||||
|
- The component is not yet stable (active refactor in progress) — wait until the conventions settle.
|
||||||
|
|
||||||
|
**Style requirements for any new `AGENTS.md`:**
|
||||||
|
- Match the encoding & line-ending of the surrounding tree (currently mixed LF/CRLF — check `git show HEAD:<dir>/README.md` first).
|
||||||
|
- Use the canonical section shape: `## Scope` → `## Where to Look` → conventions → recipes → `## Anti-Patterns` → `## Related Docs`.
|
||||||
|
- Keep it a **single point of authority**: if the root `AGENTS.md` references the component's pitfalls, replace the duplicated bullets with a single `See <path> § <section>` pointer.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Build & Test Commands
|
||||||
|
|
||||||
|
### PC Simulator (Development & Testing)
|
||||||
|
|
||||||
|
See `bsp/pc/AGENTS.md` for detailed PC Simulator build and development instructions.
|
||||||
|
|
||||||
|
**Compilation rule:**
|
||||||
|
- **NEVER run `xmake -y` directly** — it triggers a full rebuild (10+ min) and the output gets truncated in the shell tool, making it impossible to read errors.
|
||||||
|
- **ALWAYS use the helper batch scripts** in `bsp/pc/` for Windows:
|
||||||
|
```powershell
|
||||||
|
# 非 GUI 变更（增量编译，约 10-30 秒）
|
||||||
|
cd bsp\pc && cmd /c build_windows_32bit_msvc.bat
|
||||||
|
# 或 64 位
|
||||||
|
cd bsp\pc && cmd /c build_windows_64bit_msvc.bat
|
||||||
|
```
|
||||||
|
- The scripts call `build_with_summary.ps1` which runs xmake and shows only errors/warnings in a compact summary. Full log is written to `bsp/pc/build/logs/`.
|
||||||
|
- If you modify `components/airui/`, LVGL, SDL display flow, or any code behind `LUAT_USE_GUI`, use the GUI variant:
|
||||||
|
```powershell
|
||||||
|
cmd /c build_windows_32bit_msvc_gui.bat
|
||||||
|
```
|
||||||
|
- Do **not** claim build verification is complete unless the bat script output shows `Build completed successfully`.
|
||||||
|
|
||||||
|
### Build Helper Scripts (Windows)
|
||||||
|
|
||||||
|
| Script | Arch | GUI | Use Case |
|
||||||
|
|--------|------|-----|----------|
|
||||||
|
| `build_windows_32bit_msvc.bat` | x86 | No | 日常非 GUI 增量编译（推荐） |
|
||||||
|
| `build_windows_64bit_msvc.bat` | x64 | No | 64 位测试 |
|
||||||
|
| `build_windows_32bit_msvc_gui.bat` | x86 | Yes | AirUI/LVGL/SDL 变更验证 |
|
||||||
|
| `build_windows_64bit_msvc_gui.bat` | x64 | Yes | 64 位 GUI 验证 |
|
||||||
|
|
||||||
|
All scripts accept an optional `full` argument to force a clean rebuild: `cmd /c build_windows_32bit_msvc.bat full`
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Run a test case (pass exactly two script directories)
|
||||||
|
build/out/luatos-lua.exe ../../testcase/common/scripts/ ../../testcase/<feature>/<feature>_basic/scripts/
|
||||||
|
|
||||||
|
# Example
|
||||||
|
build/out/luatos-lua.exe ../../testcase/common/scripts/ ../../testcase/unit/tools/mreport/scripts/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Creating New Tests
|
||||||
|
|
||||||
|
1. Create directory: `testcase/<feature>/<feature>_basic/scripts/`
|
||||||
|
2. Create `metas.json` with test metadata
|
||||||
|
3. Create `main.lua`:
|
||||||
|
```lua
|
||||||
|
PROJECT = "testcase_name"
|
||||||
|
VERSION = "1.0.0"
|
||||||
|
require("testrunner")
|
||||||
|
sys.taskInit(function()
|
||||||
|
-- test logic
|
||||||
|
end)
|
||||||
|
sys.run()
|
||||||
|
```
|
||||||
|
4. Create `<feature>_test.lua` with functions starting with `test_`
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Coding Conventions
|
||||||
|
|
||||||
|
### C Code (Core & Modules)
|
||||||
|
|
||||||
|
**Naming:**
|
||||||
|
- Core APIs use `luat_` prefix: `luat_gpio_set`, `luat_uart_open`, `luat_spi_transfer`
|
||||||
|
- Module files: `luat_lib_<module>.c` (e.g., `luat_lib_gpio.c`, `luat_lib_uart.c`)
|
||||||
|
- Headers located in `luat/include/`
|
||||||
|
|
||||||
|
**Feature Flags:**
|
||||||
|
- Use `LUAT_USE_<FEATURE>` macros to control compilation
|
||||||
|
- Example: `LUAT_USE_GUI` enables GUI support (LVGL/SDL2)
|
||||||
|
|
||||||
|
**Code Style:**
|
||||||
|
- Follow existing patterns in `luat/modules/`
|
||||||
|
- Use `luat_` prefix for all public APIs
|
||||||
|
- Document functions with Doxygen-style comments
|
||||||
|
|
||||||
|
**Quality & Safety (project-wide C conventions):**
|
||||||
|
- **Address arithmetic**: use `uint64_t` as an intermediate when computing differences of two `uint32_t` addresses/offsets — direct subtraction on `uint32_t` silently wraps at zero. Cast each operand to `uint64_t` *before* the subtraction.
|
||||||
|
- **Atomic counters**: any counter touched by more than one thread (e.g. `ndk_thread_count`) MUST be updated through `InterlockedIncrement` / `InterlockedDecrement` (MSVC) or `__sync_add_and_fetch` / `__sync_sub_and_fetch` (GCC). Plain `++` / `--` on a shared counter is a data race.
|
||||||
|
- **Macro definitions**: when a macro body mixes `&` and `|` (or any other low-precedence operator), wrap the **entire expression** in parentheses so caller-side precedence assumptions cannot silently change semantics.
|
||||||
|
- **Resource cleanup**: if the same `free` / `release` / `memset-to-zero` sequence appears in 3+ places, extract a helper (e.g. `ndk_free_fields()` in `components/ndk/src/luat_ndk.c`) rather than duplicating the pattern.
|
||||||
|
|
||||||
|
### Lua Code (Scripts & Applications)
|
||||||
|
|
||||||
|
**Task Management:**
|
||||||
|
```lua
|
||||||
|
-- Use sys.taskInit for concurrency
|
||||||
|
sys.taskInit(function()
|
||||||
|
-- long-running task
|
||||||
|
end)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Entry Point:**
|
||||||
|
```lua
|
||||||
|
-- Scripts must end with sys.run()
|
||||||
|
sys.run()
|
||||||
|
```
|
||||||
|
|
||||||
|
**Logging:**
|
||||||
|
```lua
|
||||||
|
log.info(tag, message) -- Info level
|
||||||
|
log.warn(tag, message) -- Warning level
|
||||||
|
log.error(tag, message) -- Error level
|
||||||
|
```
|
||||||
|
|
||||||
|
**Testing:**
|
||||||
|
- Test functions MUST start with `test_` prefix
|
||||||
|
- Use `assert(condition, message)` for assertions
|
||||||
|
- Use `log.info()` for test output
|
||||||
|

### When to Use Specialized Agents
|
||||||
|
|
||||||
|
| Task Type | Agent | Description |
|
||||||
|
|-----------|-------|-------------|
|
||||||
|
| Find existing code patterns | `explore` | Search codebase structure, patterns, and styles |
|
||||||
|
| Look up library documentation | `librarian` | Search external docs, official APIs, OSS examples |
|
||||||
|
| Complex architecture decisions | `oracle` | Multi-system tradeoffs, unfamiliar patterns |
|
||||||
|
| Complex scope clarification | `metis` | Ambiguous requirements, pre-planning analysis |
|
||||||
|
| Review work plans | `momus` | Evaluate plans for clarity and completeness |
|
||||||
|
|
||||||
|
### Background Execution
|
||||||
|
|
||||||
|
Always run exploration and research tasks in background mode for parallel execution:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
task(subagent_type="explore", run_in_background=true, ...)
|
||||||
|
task(subagent_type="librarian", run_in_background=true, ...)
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Verification Checklist
|
||||||
|
|
||||||
|
Before reporting task completion, verify:
|
||||||
|
|
||||||
|
- [ ] All planned steps completed (check todo list)
|
||||||
|
- [ ] No type errors or warnings introduced
|
||||||
|
- [ ] If required, build passes in `bsp/pc` using the correct batch script: `build_windows_32bit_msvc.bat` for non-GUI changes, `build_windows_32bit_msvc_gui.bat` for AirUI/LVGL/SDL changes (never run `xmake -y` directly)
|
||||||

## Debugging Lessons & Common Pitfalls
|
||||||
|
|
||||||
|
### Memory Initialization
|
||||||
|
- `lua_newuserdata` does **NOT** zero memory — always `memset` the returned pointer
|
||||||
|
- `malloc` / `luat_heap_malloc` also do not zero — use `memset` or `calloc`
|
||||||
|
- Uninitialized pointers (e.g. `task_name`, `cb_ref`) cause delayed crashes in callback chains
|
||||||
|
|
||||||
|
### Async Event Safety
|
||||||
|
- When closing resources, consider what events are still in-flight
|
||||||
|
- Async callbacks may fire on a **different thread** — the originating context may already be freed
|
||||||
|
- Don't send state-machine events (e.g. `EV_NW_SOCKET_CLOSE_OK`) if the handler will access uninitialized state
|
||||||
|
|
||||||
|
### Async Handle Rules
|
||||||
|
- Do not copy runtime-managed async handles by `memcpy`; keep handle ownership clear
|
||||||
|
- Async close operations require the handle to remain valid until close callback fires
|
||||||
|
- Heap-allocate handles that need to outlive their creating scope

# ARP 1000ms 定时器低功耗化改造 / netdrv.arpSleep API
|
||||||
|
|
||||||
|
> 适用：基于 `net_lwip2` adapter + `netdrv` 框架的 BSP（Air8000A/U/N/AB/W/D/DB/T 等），目标是消除 `pm.power(pm.WORK_MODE, 1)` 进入 Slp1 后由 ARP 1000ms 定时器（`etharp_tmr`）带来的周期性唤醒功耗。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. 背景与问题
|
||||||
|
|
||||||
|
### 1.1 现象
|
||||||
|
|
||||||
|
Air8000A 系列模组进入低功耗模式后，预期功耗 ~40-70uA，但实测有持续 1Hz 的电流脉冲。串口/EPAT 日志可观察到：
|
||||||
|
|
||||||
|
```
|
||||||
|
03:0048:07:06464 D/net arp_pm: TICK etharp_tmr
|
||||||
|
03:0148:07:05760 D/net arp_pm: TICK etharp_tmr
|
||||||
|
03:0248:07:05440 D/net arp_pm: TICK etharp_tmr
|
||||||
|
... 每秒一次, 无限持续 ...
|
||||||
|
```
|
||||||
|
|
||||||
|
### 1.2 根因
|
||||||
|
|
||||||
|
`net_lwip2.c` 为每个 netif 维护了一个 1000ms 周期的 ARP timer（`prvlwip.arp_timer`），作用是周期性扫描 ARP 表 + 重传 ARP 请求。当编译选项是 `LUAT_NETDRV_ARP_TIMER_ALWAYS_ON` 时它永久 1Hz 跑；当编译为 on-demand 时它本应在「不需要 ARP」时停止，但：
|
||||||
|
|
||||||
|
- WIFI/CH390/AP 任一 netif 处于 `link_up` 且 `gw_mac` 尚未解析时，定时器都会启动；
|
||||||
|
- 进入低功耗前没有任何代码主动告诉 net_lwip2「我要睡了，把定时器停掉」。
|
||||||
|
|
||||||
|
### 1.3 多次尝试的失败路径
|
||||||
|
|
||||||
|
| 方案 | 结果 |
|
||||||
|
|---|---|
|
||||||
|
| 在 `luat_lib_pm.c` 的 `l_pm_power_ctrl` 加 hook：`id==LUAT_PM_POWER_WORK_MODE && onoff!=0` 时调用 `net_lwip2_arp_timer_sleep_prepare()` | 失败。Air8000 的 `pm.power(WORK_MODE,1)` 编译宏走 `LUAT_USE_DRV_PM` 分支，最初 hook 放在 `#else` 内，从未生效。 |
|
||||||
|
| 把 hook 移到 `#ifdef LUAT_USE_DRV_PM` **外** | 失败。Air8000 实际把 `pm.power(WORK_MODE,1)` 重定向到 `pm.request(Slp1)` 路径（日志只看到 `I/pm request mode=Slp1`，看不到我们注册的 `arp_pm: pm.power(...)` 行），完全绕过 `l_pm_power_ctrl`。 |
|
||||||
|
| 同时在 `l_pm_request` 加 hook | 部分固件构建仍未触发。该路径在 SoC 内部由 drv_pm 框架管理，钩子位置和编译条件因平台而异，不可靠。 |
|
||||||
|
| 用 `netdrv.ctrl(LWIP_ETH, CTRL_UPDOWN, 0)` 让 `LINK_DOWN` 事件触发 `apply_stop` | 在 ETH 场景下有效，但 STA/AP 场景下 WIFI 芯片会被直接掉电，netif 不一定经过标准 LINK_DOWN 事件。 |
|
||||||
|
|
||||||
|
### 1.4 最终选择
|
||||||
|
|
||||||
|
**抛弃所有 pm 钩子，改用一个显式的 Lua API：`netdrv.arpSleep()` / `netdrv.arpResume()`。** 由低功耗脚本在 `pm.power(WORK_MODE,1)` 之前主动调用，直接把 `EV_LWIP_ARP_TIMER_SLEEP` 事件 post 给 lwip task。完全与 pm 框架解耦。

## 3. 改动清单
|
||||||
|
|
||||||
|
### 3.1 C 层
|
||||||
|
|
||||||
|
| 文件 | 改动 | 必须重编 |
|
||||||
|
|---|---|---|
|
||||||
|
| `components/network/adapter_lwip2/net_lwip2.h` | 声明 `net_lwip2_arp_timer_sleep_prepare/wakeup_resume` 等公共 API | ✅ |
|
||||||
|
| `components/network/adapter_lwip2/net_lwip2.c` | 实现 sleep/resume API + EV_LWIP_ARP_TIMER_SLEEP/RESUME 事件处理；修复 `LINK_STATE` 钩子用 `netif_is_link_up()`（不是 `netif_is_up()`）；`any_adapter_need_arp` 同步加上 link_up 检查 | ✅ |
|
||||||
|
| `components/network/netdrv/src/luat_netdrv_lwip_etharp.c` | `gw_mac_valid` 通知（STABLE 时置 1, free 时置 0） | ✅ |
|
||||||
|
| `components/network/netdrv/src/luat_netdrv_ch390h_task.c` | 所有 CH390 处于 `CH390H_STATUS_STOPPED` 时 task 进入 `LUAT_WAIT_FOREVER` 等待，不再 1Hz 心跳；新增 `luat_ch390h_task_wakeup()` | ✅ |
|
||||||
|
| `components/network/netdrv/src/luat_netdrv_ch390h.c` | `CTRL_UPDOWN=1` 时调用 `luat_ch390h_task_wakeup()` 把 task 从 FOREVER 等待唤醒 | ✅ |
|
||||||
|
| `components/network/netdrv/binding/luat_lib_netdrv.c` | 新增 Lua API `netdrv.arpSleep()` / `netdrv.arpResume()` | ✅ |
|
||||||
|
|
||||||
|
### 3.2 Lua 层
|
||||||
|
|
||||||
|
| 文件 | 改动 | 必须重编 |
|
||||||
|
|---|---|---|
|
||||||
|
| `script/libs/dhcpsrv.lua` | 新增 `dhcpsrv.stop(srv)` API；`dhcp_task` 加 `srv.stop` 退出条件 | ❌ 刷脚本即可 |
|
||||||
|
| `module/Air8000/demo/network_routing/wifi_out_ethernet_in_wifi_in/netif_app.lua` | `dhcpsrv.create` 返回值存到 `_G.eth_dhcpsrv` / `_G.ap_dhcpsrv`，供 drv_lowpower 引用 | ❌ |
|
||||||
|
| `module/Air8000/demo/network_routing/wifi_out_ethernet_in_wifi_in/drv_lowpower.lua` | 休眠前: stop dhcpsrv + CTRL_UPDOWN=0 + `netdrv.arpSleep()`；UART1 唤醒回调: `netdrv.arpResume()` + CTRL_UPDOWN=1 + 重新 create dhcpsrv | ❌ |
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. 新增 Lua API
|
||||||
|
|
||||||
|
### 4.1 `netdrv.arpSleep()`
|
||||||
|
|
||||||
|
```lua
|
||||||
|
-- 进入 pm.power(pm.WORK_MODE, 1) 之前调用
|
||||||
|
netdrv.arpSleep()
|
||||||
|
pm.power(pm.WORK_MODE, 1)
|
||||||
|
```
|
||||||
|
|
||||||
|
- **作用**：直接 post `EV_LWIP_ARP_TIMER_SLEEP` 事件给 lwip task，task 收到后立即 stop ARP 1000ms 定时器，并把当前 running 状态保存到 `arp_timer_sleep_saved` 字段以便恢复时判断。
|
||||||
|
- **返回**：boolean。`true` 表示事件已投递（编译启用了 `LUAT_USE_NETDRV_LWIP_ARP` 且未开 `LUAT_NETDRV_ARP_TIMER_ALWAYS_ON`）；`false` 表示当前固件 ARP timer 是 always-on 模式或未启用，无效。
|
||||||
|
- **线程安全**：可在任意 task / 协程中调用。
|
||||||
|
|
||||||
|
### 4.2 `netdrv.arpResume()`
|
||||||
|
|
||||||
|
```lua
|
||||||
|
-- 唤醒回调里调用
|
||||||
|
netdrv.arpResume()
|
||||||
|
```
|
||||||
|
|
||||||
|
- **作用**：post `EV_LWIP_ARP_TIMER_RESUME` 事件给 lwip task。task 收到后清 `arp_timer_in_sleep` 标志位，然后检查 `arp_timer_sleep_saved` 或 `any_adapter_need_arp()`，若仍有 adapter 需要 ARP（admin_up + link_up + gw_mac 未解析），重新启动定时器；否则保持停止。
|
||||||
|
- **返回**：boolean，同上。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 5. 关键 C 实现要点
|
||||||
|
|
||||||
|
### 5.1 `LINK_STATE` 事件钩子修复
|
||||||
|
|
||||||
|
```c
|
||||||
|
// 文件: components/network/adapter_lwip2/net_lwip2.c
|
||||||
|
case EV_LWIP_NETIF_LINK_STATE:
|
||||||
|
{
|
||||||
|
uint8_t idx = event.Param3;
|
||||||
|
#ifndef LUAT_NETDRV_ARP_TIMER_ALWAYS_ON
|
||||||
|
// 注意: 这里是 link state 事件, 必须用 netif_is_link_up() 判断 link 层状态,
|
||||||
|
// 不能用 netif_is_up() (它是 admin state). CH390 CTRL_UPDOWN=0 只调
|

|
|
||||||
|
## 6. 业务侧使用模板
|
||||||
|
|
||||||
|
### 6.1 应用脚本（暴露 dhcpsrv 句柄）
|
||||||
|
|
||||||
|
```lua
|
||||||
|
-- netif_app.lua
|
||||||
|
local function wifi_eth_setup()
|
||||||
|
-- ...
|
||||||
|
-- 用全局变量暴露给低功耗模块, 进入休眠前会调用 dhcpsrv.stop(eth_dhcpsrv)
|
||||||
|
_G.eth_dhcpsrv = dhcpsrv.create({ adapter = socket.LWIP_ETH })
|
||||||
|
end
|
||||||
|
|
||||||
|
local function wifi_sta_ap_setup()
|
||||||
|
-- ...
|
||||||
|
_G.ap_dhcpsrv = dhcpsrv.create(dhcpsrv_opts)
|
||||||
|
end
|
||||||
|
```
|
||||||
|
|
||||||
|
### 6.2 低功耗脚本（关闭顺序）
|
||||||
|
|
||||||
|
```lua
|
||||||
|
-- drv_lowpower.lua 在 pm.power(pm.WORK_MODE, 1) 之前
|
||||||
|
|
||||||
|
-- 1) 关 dhcpsrv 协程 (消除 1Hz sys.waitUntil 唤醒)
|
||||||
|
if dhcpsrv and dhcpsrv.stop and _G.eth_dhcpsrv then
|
||||||
|
dhcpsrv.stop(_G.eth_dhcpsrv)
|
||||||
|
_G.eth_dhcpsrv = nil
|
||||||
|
end
|
||||||
|
if dhcpsrv and dhcpsrv.stop and _G.ap_dhcpsrv then
|
||||||
|
dhcpsrv.stop(_G.ap_dhcpsrv)
|
||||||
|
_G.ap_dhcpsrv = nil
|
||||||
|
end
|
||||||
|
|
||||||
|
-- 2) 关 CH390 PHY + 让 ch390_task 进入 FOREVER 等待
|
||||||
|
if netdrv and netdrv.CTRL_UPDOWN and socket.adapter and socket.adapter(socket.LWIP_ETH) then
|
||||||
|
pcall(netdrv.ctrl, socket.LWIP_ETH, netdrv.CTRL_UPDOWN, 0)
|
||||||
|
end
|
||||||
|
|
||||||
|
-- 3) 关 ARP 1000ms 定时器
|
||||||
|
if netdrv and netdrv.arpSleep then
|
||||||
|
netdrv.arpSleep()
|
||||||
|
end
|
||||||
|
|
||||||
|
-- 4) 进入低功耗
|
||||||
|
pm.power(pm.WORK_MODE, 1)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 6.3 唤醒回调（恢复顺序）
|
||||||
|
|
||||||
|
```lua
|
||||||
|
local function uart1_wakeup_read(_, len)
|
||||||
|
if len == -1 then
|
||||||
|
pm.power(pm.WORK_MODE, 0)
|
||||||
|
|
||||||
|
-- 1) 恢复 ARP 定时器 (内部判断是否真的需要启动)
|
||||||
|
if netdrv and netdrv.arpResume then
|
||||||
|
netdrv.arpResume()
|
||||||
|
end
|
||||||
|
-- 2) 重启 CH390 PHY + task
|
||||||
|
if netdrv and netdrv.CTRL_UPDOWN then
|
||||||
|
pcall(netdrv.ctrl, socket.LWIP_ETH, netdrv.CTRL_UPDOWN, 1)
|
||||||
|
end
|
||||||
|
-- 3) 重建 dhcpsrv (stop 是一次性的)
|
||||||
|
if dhcpsrv and dhcpsrv.create and not _G.eth_dhcpsrv then
|
||||||
|
_G.eth_dhcpsrv = dhcpsrv.create({adapter = socket.LWIP_ETH})
|
||||||
|
end
|
||||||
|
|
||||||
|
uart.write(1, "lowpower wakeup\r\n")
|
||||||
|
end
|
||||||
|
-- ...
|
||||||
|
end
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 7. 验证标准
|
||||||
|
|
||||||
|
### 7.1 重编 BSP（不能只刷脚本）
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
# 在 bsp/Air8000 目录下
|
||||||
|
xmake -y
|
||||||
|
# 烧入新的 .soc
|
||||||
|
```
|
||||||
|
|
||||||
|
判断标准：开机日志里必须看到这一行说明 C 改动已编入：
|
||||||
|
|
||||||
|
```
|
||||||
|
I/net arp_pm: INIT adapter=2 on-demand mode, timer created (stopped)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 7.2 进入休眠期望日志
|
||||||
|
|
||||||
|
```
|
||||||
|
I/user.lowpower_task enter
|
||||||
|
I/user.drv_lowpower stop ap dhcpsrv
|
||||||
|
I/user.dhcpsrv dhcp_task exit, adapter 3
|
||||||
|
I/user.drv_lowpower ch390 skip CTRL_UPDOWN=0 (LWIP_ETH not present)
|
||||||
|
I/user.drv_lowpower netdrv.arpSleep() -> stop ARP 1000ms timer
|
||||||
|
I/net arp_pm: API sleep_prepare -> post EV_SLEEP
|
||||||
|
I/net arp_pm: EVENT SLEEP saved=1 running=1
|
||||||
|
I/net arp_pm: apply_stop running=1 -> stop
|
||||||
|
I/pm request mode=Slp1, prev=Slp1
|
||||||
|
（之后串口不再出现 D/net arp_pm: TICK etharp_tmr）
|
||||||
|
```
|
||||||
|
|
||||||
|
### 7.3 唤醒期望日志
|
||||||
|
|
||||||
|
```
|
||||||
|
I/pm wakeup
|
||||||
|
I/net arp_pm: API wakeup_resume -> post EV_RESUME
|
||||||
|
I/net arp_pm: EVENT RESUME saved=1 in_sleep=1
|
||||||
|
I/net arp_pm: apply_start running=0 in_sleep=0 -> start 1000ms
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 8. 排障 checklist
|
||||||
|
|
||||||
|
| 现象 | 可能原因 | 排查方法 |
|
||||||
|
|---|---|---|
|
||||||
|
| 看不到 `netdrv.arpSleep()` 日志 | Lua 脚本未更新 | 重新 download script |
|
||||||
|
| 看到 Lua 日志但没 `API sleep_prepare` | C 改动没编入 | 必须重编 BSP，不能只刷脚本 |
|
||||||
|
| 看到 `apply_stop` 但 TICK 仍在 | 多个 lwip task 实例 / timer 二次注册 | 抓 `INIT` 日志确认初始化次数 |
|
||||||
|
| `not such netdrv 4` 警告 | CH390 没初始化 | 检查 `wifi_eth_setup()` 是否被调用 |
|
||||||
|
| `apply_start skip running=1 in_sleep=0` 之后又出现 TICK | LINK_UP/DOWN 误判 | 确认 net_lwip2.c 用的是 `netif_is_link_up()` 不是 `netif_is_up()` |
|
||||||
|
| 唤醒后 `arpResume` 后没自动启动 timer | `any_adapter_need_arp` 返回 false | 正常，等业务流量触发 SET_IP/LINK_UP 时会自启 |
|
||||||
|
| WIFI STA 仍 1Hz 唤醒 | LWIP_DHCP `dhcp_fine_tmr` 500ms / `dhcp_coarse_tmr` 60s | 改用静态 IP 或在 lwipopts.h 关 LWIP_DHCP |
|
||||||
|
| 仍有 10Hz 唤醒 | `LWIP_IGMP=1` (`igmp_tmr` 100ms) 或 `LWIP_IPV6_MLD=1` | 在 BSP lwipopts.h 设为 0 |
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 9. 其他功耗杀手提醒
|
||||||
|
|
||||||
|
`netdrv.arpSleep()` 只解决 ARP 1000ms 定时器。要达到最低功耗还需注意：
|
||||||
|
|
||||||
|
1. **LWIP_DHCP**：500ms / 60s 周期，必杀。静态 IP 或编译关闭。
|
||||||
|
2. **LWIP_IGMP / LWIP_IPV6_MLD**：100ms 周期，致命。`lwipopts.h` 设为 0。
|
||||||
|
3. **CH390 PULL 模式**：5ms 轮询。必须接 INT 脚走 IRQ 模式。
|
||||||
|
4. **AGPIO 高电平 + 外部下拉电阻**：每 100K 下拉 ~33uA。
|
||||||
|
5. **GNSS / GSensor 电源开关 (GPIO24)**：拉低省 88uA。
|
||||||
|
6. **WIFI 芯片 (GPIO23)**：`pm.power(pm.WIFI, 0)` 或 `gpio.setup(23, nil, gpio.PULLDOWN)` 省 42uA。
|
||||||
|
7. **dhcpsrv.lua 协程**：1Hz `sys.waitUntil`，用 `dhcpsrv.stop(srv)` 关掉。
|
||||||
|
8. **CH390 task 1Hz 心跳**：用 `netdrv.ctrl(LWIP_ETH, CTRL_UPDOWN, 0)` 让 task 进 FOREVER 等待。
|
||||||

## 10. 历史决策记录
|
||||||
|
|
||||||
|
| 日期 | 决策 | 原因 |
|
||||||
|
|---|---|---|
|
||||||
|
| 2026-06-23 | 在 `luat_lib_pm.c` 加 sleep hook | 最初方案，认为 `pm.power(WORK_MODE,1)` 会经过 `l_pm_power_ctrl` |
|
||||||
|
| 2026-06-23 | hook 移到 `#ifdef LUAT_USE_DRV_PM` 外 | 发现 Air8000 走 DRV_PM 分支，hook 被跳过 |
|
||||||
|
| 2026-06-24 | 修复 `EV_LWIP_NETIF_LINK_STATE` 用 `netif_is_link_up()` | 发现 `CTRL_UPDOWN=0` 时 link_down 被错判为 LINK_UP |
|
||||||
|
| 2026-06-24 | 抛弃 pm hook，改用 `netdrv.arpSleep()` Lua API | 发现 Air8000 `pm.power(WORK_MODE,1)` 实际走 `pm.request(Slp1)` 路径，绕过所有 pm 钩子 |

> 适用范围：LuatOS `netdrv` 框架下的 IKEv2/IPsec 隧道模式客户端
|

|
> （ESP tunnel mode）。首期已在 PC 模拟器上对接真实 strongSwan 网关

|
||||||
|
|
||||||
|
## 1. 目标与范围
|
||||||
|
|
||||||
|
在 netdrv 框架内新增 `netdrv.IPSEC` 虚拟网卡，实现：
|
||||||
|
|
||||||
|
- IKEv2 发起端（RFC 7296），服务器证书链校验 + 强制 EAP-MSCHAPv2；
|
||||||
|
- NAT-T（RFC 3948）：UDP 500 启动，探测到 NAT 后切换 4500；
|
||||||
|
- DPD 保活、CHILD_SA 到期重协商（CREATE_CHILD_SA，默认带 PFS，
|
||||||
|
KE + 新 Ni/Nr 按 RFC 7296 §2.17 派生 KEYMAT；网关不支持 PFS 时自动
|
||||||
|
无 KE 重试一次并保持旧 SA 在线）、IKE SA 到期全量重建；
|
||||||
|
- 套件扩展：IKE DH 组 19/20/21（ECP-256/384/521，RFC 4753），
|
||||||
|
ESP AES-GCM-128/256（RFC 4106 AEAD，SA 内无 INTEG transform）；
|
||||||
|
- MOBIKE（RFC 4555，opt-in，默认关闭）：本地地址变化时发送
|
||||||
|
INFORMATIONAL(UPDATE_SA_ADDRESSES + NAT-D)，处理对端发起的地址更新，
|
||||||
|
以及 established 状态下的对端地址学习；不做 ADDITIONAL_IP4_ADDRESS
|
||||||
|
通告与 COOKIE2；
|
||||||
|
- CP（Configuration Payload）下发虚拟 IPv4 + DNS；
|
||||||
|
- ESP 隧道模式（RFC 4303）AES-CBC-128/256 + HMAC-SHA1-96 /
|
||||||
|
HMAC-SHA2-256-128 或 AES-GCM-128/256，32 包反重放窗口，
|
||||||
|
ESP-in-UDP(4500)。
|
||||||
|
|
||||||
|
明确不做：IKEv1、L2TP/IPsec、ESP 传输模式、客户端证书认证、
|
||||||
|
IPv6 隧道、MOBIKE 的 ADDITIONAL_IP4_ADDRESS 通告与 COOKIE2。
|
||||||
|
MOBIKE 默认关闭（`ipsec_mobike_enable` 未配置时行为与旧版一致，
|
||||||
|
地址变化仍走断线重连）。
|
||||||
|
|
||||||
|
## 2. 文件布局
|
||||||
|
|
||||||
|
代码按用户要求拆分到独立子模块 `components/network/ipsec/`（内部头在
|
||||||
|
`include/ipsec/`，源文件在 `src/`）：
|
||||||
|
|
||||||
|
| 文件 | 说明 |
|
||||||
|
|---|---|
|
||||||
|
| `include/ipsec/ipsec_crypto.h` + `src/ipsec_crypto.c` | PRF+/HMAC、DH modp2048、IKE/CHILD 密钥派生、AUTH 计算/验签、X.509 链+SAN 校验（信任锚由 `ipsec_ca_cert_pem` 提供；不提供时默认 fail-closed，仅当显式开启 `ipsec_insecure_cert_ok` 才接受证书且仍校验 SAN） |
|
||||||
|
| `include/ipsec/ipsec_esp.h` + `src/ipsec_esp.c` | ESP 隧道封装/解封（AES-CBC + HMAC 或 AES-GCM AEAD）、SPI 方向、32 包反重放 |
|
||||||
|
| `include/ipsec/ipsec_ike.h` + `src/ipsec_ike.c` | IKEv2 状态机：SA_INIT/AUTH/EAP/CREATE_CHILD_SA/INFORMATIONAL、payload 编解码、SK 加密、NAT-T 切换、DPD、重协商、虚拟 netif 与 adapter 收发 |
|
||||||
|
| `include/ipsec/ipsec_vendor_md4.h` + `src/ipsec_vendor_md4.c` | MD4（Apache-2.0, 从 mbedTLS 2.x vendor, 自包含） |
|
||||||
|
| `include/ipsec/ipsec_vendor_chap_ms.h` + `src/ipsec_vendor_chap_ms.c` | MS-CHAPv2（BSD, 移植自 lwIP2.2 `chap_ms.c`），含 strongSwan 线格式与 RFC 3079 MSK 派生、RFC 2759 测试向量自检 |
|
||||||
|
| `src/luat_netdrv_ipsec.c` | netdrv 胶水层：setup/ctrl(UPDOWN)/dhcp(-1)/debug + 链路状态回调 |
|
||||||
|
| `components/network/netdrv/include/luat_netdrv_ipsec.h` | 胶水层头文件（保持在 netdrv/include） |
|
||||||
|
|
||||||
|
接入点：
|
||||||
|
|
||||||
|

- `luat_netdrv.h`：`luat_netdrv_ipsec_conf_t` + `conf->ipsec_conf`
|
||||||
|
- `luat_netdrv.c` / `luat_lib_netdrv.c`：setup 分发与 `ipsec_*` 参数解析

|
||||||
|
|
||||||
|
## 3. 架构与数据流
|
||||||
|
|
||||||
|
```
|
||||||
|
Lua (netdrv.setup / socket.*)
|
||||||
|
|
|
||||||
|
v
|
||||||
|
luat_netdrv_ipsec.c (setup/ctrl/dhcp/debug, IP_READY/IP_LOSE 事件)
|
||||||
|
|
|
||||||
|
v
|
||||||
|
ipsec_ike.c (IKEv2 状态机, tcpip 线程)
|
||||||
|
| netif (虚拟网卡, 全流量默认路由)
|
||||||
|
| | netif output -> ESP 封装 -> adapter UDP TX(4500)
|
||||||
|
| | adapter RX(4500) -> IKE(4字节零前缀) 或 ESP -> 内层 IP 注入
|
||||||
|
|
|
||||||
|
+-- network_ctrl_t (luat_network_adapter, 单 socket: 500 -> 4500)
|
||||||
|
```
|
||||||
|
|
||||||
|
- IKE 与 ESP 共用同一个 adapter UDP socket：先在 500 上完成
|
||||||
|
IKE_SA_INIT，NAT 探测后切换到本地/远端 4500（RFC 3948 非 ESP
|
||||||
|
marker 区分 IKE 与 ESP）。这是标准 NAT-T 形态，避免了双 socket
|
||||||
|
同端口绑定的问题。
|
||||||
|
- 所有状态机工作经 `tcpip_callback_with_block` 汇聚到 tcpip 线程；
|
||||||
|
adapter 回调只拷贝数据并投递，与 L2TP/OpenVPN 客户端一致。
|
||||||
|
- CP 下发虚拟 IP 后 `netif_set_addr` + `netif_set_default`，DNS 写入
|
||||||
|
`network_set_dns_server`。
|
||||||
|
|
||||||
|
## 4. 协议要点与互操作细节
|
||||||
|
|
||||||
|
- 套件：IKE `{aes256-sha256, aes128-sha1} × {modp2048, ecp256, ecp384,
|
||||||
|
ecp521}!`（8 个提案，DH14 优先；响应者选中其它组时按 RFC 7296 §2.7
|
||||||
|
的 INVALID_KE 通知重试，IKE_SA_INIT 默认先发 DH14 的 KE）；
|
||||||
|
ESP `aes256-sha256, aes128-sha1, aes256gcm16, aes128gcm16!`
|
||||||
|
（AEAD 提案无 INTEG transform，transform id 20 + KEY_LENGTH 属性）。
|
||||||
|
- CHILD_SA 重协商默认带 PFS：请求载荷顺序 `SA | Ni | KE | TSi | TSr`，
|
||||||
|
使用 IKE_SA_INIT 协商出的 DH 组生成新的临时密钥对；响应解析新 Nr 与
|
||||||
|
KE，KEYMAT = prf+(SK_d, g^ir | Ni | Nr)。响应缺少 KE 或带
|
||||||
|
NO_PROPOSAL_CHOSEN/TS_UNACCEPTABLE 时，自动无 KE 重试一次并保持旧 SA
|
||||||
|
在线（与旧版行为一致）。
|
||||||
|
- MOBIKE 更新载荷顺序：`N(UPDATE_SA_ADDRESSES) | N(NAT_DETECTION_SOURCE_IP)
|
||||||
|
| N(NAT_DETECTION_DESTINATION_IP)`（RFC 4555 §2.2），NAT-D 复用
|
||||||
|
IKE_SA_INIT 的 SHA-1 哈希方式；对端发起的更新用当前本地 IP 校验
|
||||||
|
目标 NAT-D，不匹配则忽略；established 状态下的地址学习只发生在
|
||||||
|
密码学验证通过之后：ESP 报文在 ICV/解密成功后、对端
|
||||||
|
UPDATE_SA_ADDRESSES 在 SK 解密 + NAT-D 校验通过后、已认证的
|
||||||
|
INFORMATIONAL 响应在 ICV 校验通过后（RFC 4555 §3，
|
||||||
|
未认证报文一律不得改写对端地址）。
|
||||||
|
- IKE 请求单在途槽位：`pending_msgid/last_tx` 全 client 一份，
|
||||||
|
DPD/MOBIKE 更新/CREATE_CHILD_SA 任一在途时其余请求让路（下一秒
|
||||||
|
tick 重试）；INFORMATIONAL 响应（DPD/MOBIKE ack）经 SK 解密 +
|
||||||
|
ICV 校验后才采信；msgid 全链路 32 位（RFC 7296 单调不回绕）。
|
||||||
|
- IKE SK 载荷：AES-CBC + HMAC；**ICV 只覆盖 IKE 报文本身**（strongSwan
|
||||||
|
收到 4500 报文会先剥离 4 字节非 ESP marker 再校验）。
|
||||||
|
- ESP AEAD（RFC 4106）：8 字节显式 IV，GCM IV = salt(4) | IV(8)，
|
||||||
|
AAD = SPI | SEQ，ICV 16 字节，padding 按 4 字节对齐；KEYMAT 每方向为
|
||||||
|
`enc_key(16/32) + salt(4)`（RFC 7296 §3.3.2），无 INTEG 密钥。
|
||||||
|
- AUTH：EAP 模式按 RFC 7296 §2.16 用 MSK 作为共享密钥；
|
||||||
|
`"Key Pad for IKEv2"` 为 17 字节（不含 NUL）。
|
||||||
|
- MSK：按 strongSwan 的 RFC 3079 实现——
|
||||||
|
`master=SHA1(HH|NT-Response|Magic1)`，
|
||||||
|
`recv/send=SHA1(master[0:16]|0x00*40|Magic2/3|0xF2*40)`，
|
||||||
|
`MSK=recv[0:16]|send[0:16]|0x00*32`。
|
||||||
|
- MS-CHAPv2 线格式采用 strongSwan/Windows 客户端格式：
|
||||||
|
`opcode|id|ms_length|value_size|...`（区别于 RFC 2759 排版）。
|
||||||
|
- ESP SPI 方向：发起端**发送**用响应者分配的 SPI（SAr2），**接收**
|
||||||
|
用自己提议的 SPI（SAi2）。
|
||||||
|
- 证书链：配置了 `ipsec_ca_cert_pem` 时按该信任锚做链校验并校验
|
||||||
|
SAN `ipsec.air32.cn`；未配置时默认 **fail-closed**（固件不再内置任何
|
||||||
|
信任锚），仅当显式设置 `ipsec_insecure_cert_ok=true` 才接受服务器证书，
|
||||||
|
且仍强制 SAN 匹配。mbedTLS 校验需传 `mbedtls_x509_crt_profile_default`，
|
||||||
|
PEM 缓冲需 NUL 结尾（mbedTLS 3.x 的 PEM 识别条件）。
|
||||||
|
|
||||||
|
## 5. 配置参考（Lua）
|
||||||
|
|
||||||
|
```lua
|
||||||
|
netdrv.setup(socket.LWIP_USER1, netdrv.IPSEC, {
|
||||||
|
ipsec_remote_ip = "154.8.159.79", -- 网关 IP（仅字面量）
|
||||||
|
ipsec_remote_port = 500, -- IKE 端口, 默认 500
|
||||||
|
ipsec_username = "vpnuser",
|
||||||
|
ipsec_password = "xxxx",
|
||||||
|
ipsec_san = "ipsec.air32.cn", -- 服务器 SAN 校验
|
||||||
|
-- ipsec_ca_cert_pem = "-----BEGIN CERTIFICATE-----...", -- 建议配置信任锚;
|
||||||
|
-- -- 未配置且未开启 insecure 时无法连接 (fail-closed)
|
||||||
|
-- ipsec_insecure_cert_ok = false, -- 默认 false; true 表示无 CA 时仅校验 SAN 即接受
|
||||||
|
ipsec_mtu = 1400,
|
||||||
|
ipsec_retry_enable = true,
|
||||||
|
ipsec_retry_base_ms = 1000,
|
||||||
|
ipsec_retry_max_ms = 60000,
|
||||||
|
-- ipsec_mobike_enable = true, -- MOBIKE 双向地址更新 (默认关闭)
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
`ipsec_mobike_enable`：布尔，默认 `false`。开启后客户端在 1s tick 轮询
|
||||||
|
本地地址，变化时发送 UPDATE_SA_ADDRESSES；底层 socket 关闭但传输仍在线
|
||||||
|
时重开同端口 socket 并走更新流程而非全量重建；同时支持对端发起的地址
|
||||||
|
更新与 established 状态下的地址学习。仅 utest 构建提供测试钩子
|
||||||
|
`netdrv.ipsec_sim_addr_change(id)` 模拟一次本地地址变更。
|
||||||
|
|
||||||
|
## 6. 联调记录（2026-08-12, PC 模拟器 ↔ ipsec.air32.cn）
|
||||||
|
|
||||||
|
联调期间发现并修复的问题：
|
||||||
|
|
||||||
|
| # | 现象 | 根因 | 修复 |
|
||||||
|
|---|---|---|---|
|
||||||
|
| 1 | 网关对 IKE_SA_INIT 无响应 | Ni/NAT-D 载荷的 Next Payload 误用 notify 值(16388)而非载荷类型(41) | 改为 `IPSEC_PAYLOAD_NOTIFY` |
|
||||||
|
| 2 | IKE_AUTH 无响应, 网关日志 `message ID 16777216, expected 1` | msgid 以单字节写入 (`01 00 00 00`) 而非 4 字节大端 | `ike_put32(msg+20, msgid)` |
|
||||||
|
| 3 | 网关日志 `MAC verification failed` | mbedTLS 3 `aes_crypt_cbc` 会把最后一组密文写回 IV 缓冲, 覆盖了包内 IV | 用独立 IV 缓冲 |
|
||||||
|
| 4 | 网关日志 `MAC verification failed`（修复 3 后仍失败） | 4500 上 ICV 把 4 字节零前缀算进去了, 而 strongSwan 收到会先剥离 | ICV 只覆盖 IKE 报文 |
|
||||||
|
| 5 | `trust anchor parse failed -0x2180` | mbedTLS 3.x 仅当缓冲区 NUL 结尾才识别 PEM | 内嵌/用户 PEM 均保留 NUL 结尾 |
|
||||||
|
| 6 | `cert chain verify failed flags=0xFFFFFFFF` | `mbedtls_x509_crt_verify_with_profile` 的 profile 传 NULL 返回 BAD_INPUT_DATA | 传 `mbedtls_x509_crt_profile_default` |
|
||||||
|
| 7 | 服务器只发叶子证书, 链校验失败 | strongSwan `leftsendcert=always` 只发叶子；Let's Encrypt 2026 新链 | 内置 YE2/ISRG Root YE/ISRG Root X2 中间 CA |
|
||||||
|
| 8 | `server AUTH signature verification failed` | 裸 r\|s 转 DER 时长度公式少算 2 字节 | 修正 `total=6+r+s+pad` |
|
||||||
|
| 9 | 服务器 `INVALID_SYNTAX` 拒绝 EAP Identity 响应 | EAP 载荷构建后未 `p += plen`, 内层为空 | 修复三处 EAP 载荷 |
|
||||||
|
| 10 | `unhandled MS-CHAPv2 request opcode 1` | 用 RFC 2759 排版解析 strongSwan 的 Challenge | 按 strongSwan 线格式解析 |
|
||||||
|
| 11 | 最终 AUTH 被拒 | 内层 `"Key Pad for IKEv2"` 用 `sizeof`（含 NUL 18 字节） | 用 17 字节 |
|
||||||
|
| 12 | 最终 AUTH 被拒（修复 11 后仍失败） | MSK 的 master 用 `sizeof(inner)=79`（实际 67）；且 0x36/0x5C 填充与 strongSwan 的 0x00/0xF2 不符；32 字节 key 从 20 字节 digest 越界拷贝 | 按 strongSwan 实现重写 MSK 派生 |
|
||||||
|
| 13 | ESP 无回包, 网关 `XfrmInNoStates` | ESP SPI 方向反了（发送用了自己提议的 SPI） | 发送用 SAr2 的 SPI |
|
||||||
|
| 14 | 隧道 IP 与策略不匹配 | CP 的 IPv4 字节序（`ip4_addr_set_u32` 需先 `lwip_htonl`） | 恢复 `lwip_htonl(ike_get32())` |
|
||||||
|
| 15 | 证书校验 `NOT_TRUSTED`（flags=0x8） | 网关改用私建 CA（`CN=IKEv2 VPN CA`，自签 10 年），strongSwan 只发叶子，内置 ISRG Root X1 / LE 中间链不再适用 | 测试脚本改从 `scripts/ikev2-ca.crt` 读取 CA 作为 `ipsec_ca_cert_pem` 传入；同时按需求移除固件内置信任锚，未配 CA 的默认行为在后续提交中收紧为 fail-closed（需显式 `ipsec_insecure_cert_ok=true` 才接受证书，且仍校验 SAN） |
|
||||||
|
|
||||||
|
服务器侧配合项（已处理，用户授权调试）：
|
||||||
|
|
||||||
|
- 云主机 `dirtyfrag.conf` 禁用 `esp4` 内核模块（`install esp4 /bin/false`），
|
||||||
|
导致 XFRM SAD 安装失败（`netlink error: Requested type not found (93)`）：
|
||||||
|
已注释该规则并加载 `esp4`/`xfrm_user`/`xfrm4_tunnel`；
|
||||||
|
- `ipsec.secrets` 私钥声明为 `: RSA` 但实际是 ECDSA P-384：
|
||||||
|
已改为 `: ECDSA`；
|
||||||
|
- 联调后 `charondebug` 已恢复 `ike 2`，`esp=aes256-sha256, aes128-sha1!`
|
||||||
|
已恢复原样。
|
||||||
|
|
||||||
|
## 7. 测试结果（PC 模拟器, testcase/unit/net/netdrv_ipsec_basic）
|
||||||
|
|
||||||
|
- `connect`：IKE_SA_INIT → 证书链+SAN 校验 → 服务器 AUTH 验签 →
|
||||||
|
EAP-MSCHAPv2（含服务器 Authenticator Response 校验）→ 双端 AUTH →
|
||||||
|
CP 下发虚拟 IP/DNS → 隧道上线 → 隧道内 TCP 到网关 SSH 收到 banner，
|
||||||
|
**3 passed / 0 failed**；
|
||||||
|
- `badpass`：错误密码 → EAP 失败 → 不 ready，**通过**；
|
||||||
|
- `sanit`：错误 SAN → 证书校验拒绝 → 不 ready，**通过**。
|
||||||
|
|
||||||
|
> 前置：`testcase/unit/net/netdrv_ipsec_basic/scripts/ikev2-ca.crt`
|
||||||
|
> （网关私建 CA）必须存在，测试会把它作为 `ipsec_ca_cert_pem` 传入；
|
||||||
|
> 测试账号凭据通过环境变量 `LUAT_IPSEC_USERNAME` / `LUAT_IPSEC_PASSWORD`
|
||||||
|
> 注入（不随源码分发），未设置时测试跳过。
|
||||||
|
> 固件默认 fail-closed：未传 `ipsec_ca_cert_pem` 且未显式开启
|
||||||
|
> `ipsec_insecure_cert_ok` 时拒绝连接（固件不再内置任何信任锚）。
|
||||||
|
|
||||||
|
## 8. 遗留与后续
|
||||||
|
|
||||||
|
- 集成联调（需网关侧重配，未完成项见交付说明）：
|
||||||
|
- PFS：网关 `pfs=yes` + 缩短 lifetime，验证重协商日志、DPD、隧道不断流；
|
||||||
|
- ECP/GCM：网关 `ike=aes256-sha256-ecp256!` / `esp=aes256gcm16!` 建连；
|
||||||
|
- MOBIKE：`netdrv.ipsec_sim_addr_change` 触发 UPDATE_SA_ADDRESSES，
|
||||||
|
网关 `mobike=no` 时回退重连。
|
||||||
|
- 硬件 BSP：需确认目标板 lwip 导出符号（`pbuf/netif/sys/ip4_input`）
|
||||||
|
与 adapter 行为，并按验收清单在目标板重跑；
|
||||||
|
- 服务器 FORWARD 链的 IPsec 池 ACCEPT 规则与 `rightsourceip`
|
||||||
|
段需按实际网络调整（当前云主机 iptables 规则与池配置不完全一致，
|
||||||
|
隧道到网关本机可用，跨子网转发需核对）；
|
||||||
|
- `netdrv.debug` 会输出 IKE/ESP 帧日志（含 SK 明文转储仅调试用）。
|
||||||

## fatfs

### fatfs::setup_module_not_found [high]
|
||||||
|
- **Expected**: 当 `fatfs` 模块在 PC BSP 中不可用时, `mount_fatfs.setup()` 应返回 false 让 `main.lua` 自跳过整个测试套
|
||||||
|
- **Actual**: `mount_fatfs.lua:9` 的 `require("fatfs")` 在 PC BSP 上直接抛出 "module 'fatfs' not found", VM 在 `main.lua` 检测 `fs_ok` 之前就崩溃退出, 测试套根本没有 self-skip 机会

|
- **Source**: `testcase/utest/fs/vfs_uniform/scripts/mount_fatfs.lua:9`

|
- **Repro**:
|

|
1. 在 PC 模拟器上跑 `vfs_uniform_fatfs`
|
||||||
|
2. `mount_fatfs.setup()` 里 `require("fatfs")` 失败, 抛错
|
||||||
|
3. 错误沿着 `require` 链 `vfs_uniform_mount.lua -> mount_fatfs.lua` 一路冒泡, VM 退出

### fatfs::pc_build_fatfs_module_unavailable [high]
|

|
- **Expected**: PC BSP 应当能 `require("fatfs")` 加载内置 fatfs 模块 (因为 `LUAT_USE_FATFS` 已在 `bsp/pc/include/luat_conf_bsp.h:145` 定义, 且 `luaopen_fatfs` 在 `bsp/pc/port/luat_base_mini.c:160` 注册)
|
||||||
|
- **Actual**: 当前 PC 二进制 `bsp/pc/build/out/luatos-lua.exe` 对 `require("fatfs")` 返回 "module not found", 同样 `require("uart")`/`require("json")` 等内置模块也都失败; 只有 `io`/`os`/`string`/`log`/`rtos` 这类 globals 仍可用. 整个 fatfs 测试套无法在 PC 上执行
|
||||||
|
- **Source**: `bsp/pc/port/luat_base_mini.c:159-161` (注册) vs PC BSP 实际加载行为
|
||||||
|
- **Repro**:
|
||||||
|
1. 写 `print(type(require("fatfs")))` 的最小 main.lua
|
||||||
|
2. 用 `bsp/pc/build/out/luatos-lua.exe ... /tmp/test/` 跑

## tfs

### tfs::tfs_mount_format_name_marker [high]
|
||||||
|
- **Expected**: `lf.mount(flash, "/tfs0", 0, 256*1024, {fs="tfs"})` 在 PC 模拟器空白 flash 上应返回 true, mount 后 VFS 即可在 /tfs0 上读写文件
|
||||||
|
- **Actual**: 第一次 `lf.mount` 返回 false, 日志显示 `tfs: format ret=0 read_errors=0` (format 成功) 紧接着 `tfs: open name marker failed` 和 `tfs: format mount failed`, 之后才出现 `tfs: anchor written chunk=0 seq=4096`; 二次 mount 找到 anchor 但仍 `tfs: open name marker failed` 触发 `tfs: probe failed, reformatting`, 再次 `tfs: open name marker failed` 后 `tfs: format or mount failed`
|
||||||
|
- **Source**: `components/little_flash/luat_little_flash_tfs.c:478` (`lf_tfs_write_name_marker` 中 `tfs_open` 失败) 与 `:1226` (`tfs: format mount failed`)

- **Repro**:
|
||||||
|
1. 在 PC 上跑 `D:/github/LuatOS/bsp/pc/build/out/luatos-lua.exe` 并加载 vfs_uniform_tfs/scripts
|
||||||

2. `mount_tfs.lua` 调 `spi.deviceSetup(1,255,...)` + `lf.init(spidev)` + `lf.mount(flash,"/tfs0",0,256*1024,{fs="tfs"})`
|

### tfs::all_tests_skipped_mount_unavailable [high]
|
||||||
|
- **Expected**: 30 个共享用例应在 /tfs0 上运行, 大部分通过
|
||||||
|
- **Actual**: 30 个用例全部 0/0 跳过, 因为 tfs mount 失败直接 `os.exit(0)`, 没有任何用例被执行
|
||||||
|
- **Source**: 测试 `main.lua` 在 `mount.setup()` 返回 false 时退出; 根因是 tfs mount bug
|
||||||

- **Repro**:
|
||||||
|
1. 跑 vfs_uniform_tfs (与上面 tfs_mount_format_name_marker 同一触发条件)

## pgfs

||||||
|
|
||||||
|
> pgfs mounted successfully on PC simulator (`/pgfs0`, 256KB partition, virtual NAND
|
||||||
|
> W25N01GVZEIG). However the FTL has very few free blocks at mount time (`next=1, total=2,
|
||||||
|
> bad=0`), and the GC allocator reports `alloc_segment: no free blocks` whenever a write
|
||||||
|
> triggers a new segment allocation. This causes most write/read roundtrip assertions to
|
||||||
|
> fail with 0-byte content. Each test below is a separate symptom of the same root cause
|
||||||
|
> (or, in two cases, an independent semantic bug).

### pgfs::test_refcount_remove_open_fails [med]

# netdrv L2TPv2 客户端驱动设计文档
|
||||||
|
|
||||||
|
> 适用范围：在 LuatOS `netdrv` 框架下新增 L2TPv2（RFC 2661）客户端驱动（LAC），
|
||||||
|
> 当前首期落地 PC 模拟器（`bsp/pc`），硬件 BSP 按需开启 `LUAT_USE_NETDRV_L2TP`。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. 背景与目标
|
||||||
|
|
||||||
|
LuatOS 需要在内网/办公网场景下提供「二层隧道 + PPP 拨号」的能力，典型形态是
|
||||||
|
接入企业 LNS（L2TP Network Server）获得内网 IP 并访问内网资源。
|
||||||
|
|
||||||
|
需求边界（与 lwip 自带 `pppol2tp.c` 的能力边界一致）：
|
||||||
|
|
||||||
|
- ✅ L2TPv2 客户端（LAC），PPP over L2TP（UDP 隧道）
|
||||||
|
- ✅ PPP 认证：PAP + CHAP(MD5)；可选 L2TP 隧道共享密钥认证（`l2tp_secret`）
|
||||||
|
- ❌ LNS（服务端）、L2TPv3、隧道切换、多隧道/多会话
|
||||||
|
- ❌ MSCHAPv2 / MPPE / EAP / CCP
|
||||||
|
|
||||||
|
核心约束：**外层 UDP 传输一律走 LuatOS network adapter**（`network_ctrl_t` UDP
|
||||||
|
模式，与 OpenVPN 客户端一致），不直接创建 lwip `udp_pcb`。这样 VPN 虚拟网卡与
|
||||||
|
底层物理网卡（4G/WiFi/ETH/CH390H）完全解耦，底层可以是任意 netdrv 适配器。
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|

```
|
||||||
|
|
||||||
|
### 2.1 分层
|
||||||
|
|
||||||
|
1. **胶水层**（`luat_netdrv_l2tp.c`）：把 L2TP 客户端包装成标准 `luat_netdrv_t`
|
||||||
|
驱动，负责配置拷贝、`LUAT_NETDRV_CTRL_UPDOWN` 控制、链路状态上报。
|
||||||
|
2. **客户端核心**（`components/network/l2tp/src/`，按协议层拆为三个文件）：
|
||||||
|
- `l2tp_client.c`：生命周期/状态机/定时器/网络适配器传输
|
||||||
|
（`l2tp_udp_send`、`l2tp_timeout`、重连退避、`l2tp_client_*` API）；
|
||||||
|
- `l2tp_ctrl.c`：L2TPv2 控制面从 lwip22 `netif/ppp/pppol2tp.c` 移植，
|
||||||
|
仅替换 UDP 收发为 `network_tx/network_rx`，去掉 `udp_pcb` 与传输
|
||||||
|
netif 参数（线格式/AVP 构造解析、ns/nr 窗口、定时重传）；
|
||||||
|
- `l2tp_ppp.c`：PPP 会话运行在 vendor 的 lwIP PPP 栈上，
|
||||||
|
`struct link_callbacks` 的 `write/netif_output` 走 L2TP 数据封装，
|
||||||
|
并处理 `ppp_status_cb` 链路状态回调。
|
||||||
|
- 跨文件原型在 `components/network/l2tp/include/l2tp/`（`l2tp_ctrl.h` /
|
||||||
|
`l2tp_ppp.h`），公共客户端 API 在 `l2tp/l2tp_client.h`。
|
||||||
|
3. **PPP 栈**（`components/network/l2tp/src/ppp/`）：lwIP 2.2.1
|
||||||
|
`ppp.c/lcp.c/ipcp.c/auth.c/fsm.c/upap.c/chap-new.c/chap-md5.c/magic.c/utils.c`
|
||||||
|
的 vendor 副本（保留 BSD 许可头，注明来源），由构建系统按需编译。
|
||||||
|
|
||||||
|
### 2.2 线程模型
|
||||||
|
|
||||||
|
- `create/connect/close` 与 `ppp_input` 的投递统一 marshal 到 lwip core 线程
|
||||||
|
（`tcpip_callback_with_block`，模式同 WG 驱动的 `exec_netif_add`）；
|
||||||
|
- network adapter 回调（运行在 adapter 任务/Lua 主线程）内**只做数据拷贝**，
|
||||||
|
通过 `tcpip_callback` 投递给 tcpip 线程，PPP 状态机绝不在 adapter 线程执行；
|
||||||
|
- `transport_err` 标志由 adapter 回调置位，由 500ms 周期定时器（tcpip 线程）
|
||||||
|
消费，避免跨线程直接操作 PPP 状态机。
|
||||||
|
|
||||||
|
### 2.3 就绪信号
|
||||||
|
|
||||||
|
PPP 的 `sifup()` 在 `np_up()` 把 phase 推进到 `PPP_PHASE_RUNNING` **之前**就会
|
||||||
|
回调 `link_status_cb(PPPERR_NONE)`，因此驱动的 ready 判定使用 `ppp->if4_up`
|
||||||
|
（`sifup` 内部先置位再回调），而不是 phase==RUNNING，否则会出现一次误报
|
||||||
|
`IP_LOSE` 且不再上报 `IP_READY` 的竞态。
|
||||||
|
|
||||||

## 3. 方案选择与取舍
|
||||||
|
|
||||||
|
### 3.1 传输层：network adapter UDP 而非 lwip `udp_pcb`
|
||||||
|
|
||||||
|
| 方案 | 结论 |
|
||||||
|
|---|---|
|
||||||
|
| 直接创建 lwip `udp_pcb` 走底层 netif | 与 4G/WiFi/ETH 等 LuatOS 自有适配器耦合，需要额外的 netif 路由/ARP 处理，硬件差异大 |
|
||||||
|
| `network_ctrl_t` UDP（本方案） | 与 OpenVPN 客户端一致，底层网卡即插即用；天然支持「LNS 从随机源端口应答」（posix 适配器不 connect UDP socket） |
|
||||||
|
|
||||||
|
代价：多一次 adapter 层数据拷贝，VPN 隧道吞吐受 adapter 缓冲限制
|
||||||
|
（`network_tx/rx` 单包缓冲，L2TP 数据面当前使用 1600B 栈缓冲）。
|
||||||
|
|
||||||
|
### 3.2 PPP 栈：vendor lwip22 源码 vs 自己实现
|
||||||
|
|
||||||
|
lwip22 自带完整的 `ppp.c` 系列（LCP/IPCP/PAP/CHAP/FSM/魔法数），直接 vendor
|
||||||
|
到 `components/network/l2tp/src/ppp/` 并配套两个移植补丁：
|
||||||
|
|
||||||
|
1. **`ppp_pcb` 改用 `mem_malloc/mem_free`**：本仓库 lwip22 的 `memp_std.h`
|
||||||
|
裁剪掉了 PPP/PPPOL2TP 内存池，vendor 副本内自行 `LWIP_MEMPOOL_DECLARE`
|
||||||
|
可以编译，但为减少静态池开销并贴合本仓库约定，改为堆分配。
|
||||||
|
2. **MD5 走外部 mbedTLS**：`LWIP_USE_EXTERNAL_MBEDTLS=1` 把 `lwip_md5_*`
|
||||||
|
映射到 LuatOS 已有 mbedtls（`MBEDTLS_MD5_C` 在 PC 与硬件配置均已启用），
|
||||||
|
不再编译 lwip 内嵌 PolarSSL 副本。
|
||||||
|
|
||||||
|
### 3.3 编译选项覆盖：`luat_ppp_opts_override.h`
|
||||||
|
|
||||||
|
`bsp/pc/include/lwipopts.h` 写死 `PPP_SUPPORT 0`，且会**无条件重定义**，因此
|
||||||
|
per-file 命令行宏会被覆盖；同时 `ppp_opts.h` 的 `#if PPP_SUPPORT` 块在 override
|
||||||
|
生效之前求值（其中定义的 FSM/UPAP/CHAP/LCP 超时、`MAXNAMELEN/MAXSECRETLEN`、
|
||||||
|
`PPP_MRU`、`PPP_IPV4_SUPPORT` 等全部缺失）。
|
||||||
|
|
||||||
|
解决办法：xmake 仅对 vendor PPP 文件与 L2TP 客户端文件附加
|
||||||
|
`LUAT_L2TP_PPP_BUILD=1`，并在 `ppp_opts.h` 之后强制 include
|
||||||
|
`luat_ppp_opts_override.h`，统一恢复特性集：
|
||||||
|
|
||||||
|
```
|
||||||
|
PPP_SUPPORT=1, PPPOL2TP/PPPOS/PPPOE=0, LWIP_PPP_API=0,
|
||||||
|
PAP_SUPPORT=1, CHAP_SUPPORT=1, MSCHAP/EAP/CCP/MPPE/VJ/LQR=0,
|
||||||
|
PPP_IPV4_SUPPORT=(LWIP_IPV4), PPP_IPV6_SUPPORT=0, PPP_SERVER=0,
|
||||||
|
LWIP_USE_EXTERNAL_MBEDTLS=1, MEMP_NUM_PPP_PCB=1
|
||||||
|
```
|
||||||
|
|
||||||
|
配套提供 `components/network/l2tp/include/ppp_settings.h`：`lwip22/include/arch/cc.h`
|
||||||
|
无条件定义 `PPP_INCLUDE_SETTINGS_HEADER`，但仓库从未提供该 port 头文件
|
||||||
|
（PPP 此前从未编译），本文件为空实现（选项全部走 override 头）。
|
||||||
|
|
||||||
|
> 注意：这些宏只作用于 vendor PPP 文件与 L2TP 客户端文件，**不是全局宏**。
|
||||||
|
> 全局开启 `PPP_SUPPORT` 会触发 `lwip22/core/init.c` 的
|
||||||
|
> `#error "PPP_SUPPORT needs at least one of PPPOS_SUPPORT..."` 编译检查。
|
||||||
|
|
||||||
|
### 3.4 L2TP 控制面：自实现（`PPPOL2TP_SUPPORT=0`）
|
||||||
|
|
||||||
|
lwip 的 `pppol2tp.c` 与 `udp_pcb` 强耦合，且其头文件要求
|
||||||
|
`PPPOL2TP_SUPPORT=1`。本驱动把控制面逻辑平移到
|
||||||
|
`l2tp_ctrl.c`（常量、AVP 构造/解析、ns/nr 窗口、定时重传均照搬），
|
||||||
|
传输改为 adapter 调用，因此 vendor PPP 文件以 `PPPOL2TP_SUPPORT=0` 编译，
|
||||||
|
避免 `pppol2tp.c` 参与编译。
|
||||||
|
|
||||||
|
### 3.5 认证与隧道密钥
|
||||||
|
|
||||||
|
- `ppp_set_auth(ppp, PPPAUTHTYPE_ANY, user, passwd)`：PAP/CHAP-MD5 均可；
|
||||||
|
- `l2tp_secret` 非空时按 RFC 2661 在 SCCRQ/SCCRP/SCCCN 中携带
|
||||||
|
Challenge / Challenge-Response AVP（MD5(消息类型|secret|challenge)）。
|
||||||
|
- 认证选项由**对端**在 LCP ConfReq 中提出：lwip 客户端的 LCP ConfReq 本身
|
||||||
|
不携带 auth 选项（`lcp_addci` 使用 gotoptions，客户端侧该位不置位），
|
||||||
|
因此 LNS 必须主动要求认证（真实 LNS 行为一致）。
|
||||||
|
|
||||||
|
### 3.6 断线检测与自动重连
|
||||||
|
|
||||||
|
- **PPP 层**：LCP keepalive（3s 间隔、3 次失败）检测静默断线（对端不响应）；
|
||||||
|
对端 StopCCN 在 DATA 阶段不主动断开（沿用 pppol2tp 语义），由 keepalive 兜底。
|
||||||
|
- **传输层**：`EV_NW_RESULT_CLOSE`/`Param1!=0` 置 `transport_err`，500ms 周期
|
||||||
|
定时器消费并触发重连。
|
||||||
|
- 重连策略：指数退避（base 1s，max 60s，可配置），传输离线时按 base 轮询；
|
||||||
|
用户主动 `CTRL_UPDOWN=0` 不重连。
|
||||||
|
- 在线判定使用 setup 时捕获的 `transport_index`，而非运行时默认 adapter：
|
||||||
|
netdrv 虚拟网卡注册后 `network_register_get_default()` 会变成 USERx 自身，
|
||||||
|
若用运行时默认值会导致「传输离线」误判。
|
||||||
|
|
||||||
|
### 3.7 数据面 MTU 与缓冲
|
||||||
|
|
||||||
|
PPP MRU 默认 1450（`L2TP_DEFAULT_MTU`，可用 `l2tp_mtu` 配置）；L2TP 数据头 6B
|
||||||
|
（flags + tunnel id + session id）。发送侧把 pbuf 拼成扁平缓冲后走
|
||||||
|
`network_tx`（1600B 栈缓冲），接收侧同样扁平缓冲 -> pbuf -> `ppp_input`。
|
||||||
|

|
### 4.2 xmake 接线要点（`bsp/pc/xmake.lua`）
|
||||||
|
|
||||||
|
```lua
|
||||||
|
-- 剔除 lwip22 自带 PPP（避免与 vendor 副本重复编译）
|
||||||
|
remove_files(lwip_path .. "netif/ppp/**.c")
|
||||||
|
|
||||||
|
-- netdrv 核心（VPN 子模块已拆出为独立目录）
|
||||||
|
add_files(luatos .. "components/network/netdrv/**.c")
|
||||||
|
|
||||||
|
-- L2TP 子模块：头文件路径 + vendor PPP + 客户端按文件附加编译宏
|
||||||
|
add_includedirs(luatos .. "components/network/l2tp/include")
|
||||||
|
add_includedirs(luatos .. "components/network/l2tp/src/ppp")
|
||||||
|
add_files(luatos .. "components/network/l2tp/src/ppp/*.c",
|
||||||
|
{defines = {"LUAT_L2TP_PPP_BUILD=1"}})
|
||||||
|
add_files(luatos .. "components/network/l2tp/src/l2tp_client.c",
|
||||||
|
luatos .. "components/network/l2tp/src/l2tp_ctrl.c",
|
||||||
|
luatos .. "components/network/l2tp/src/l2tp_ppp.c",
|
||||||
|
{defines = {"LUAT_L2TP_PPP_BUILD=1"}})
|
||||||
|
add_files(luatos .. "components/network/l2tp/src/luat_netdrv_l2tp.c")
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4.3 Lua 用法
|
||||||
|
|
||||||
|
```lua
|
||||||
|
netdrv.setup(socket.LWIP_USER1, netdrv.L2TP, {
|
||||||
|
l2tp_remote_ip = "10.0.0.1", -- 必填，LNS IP（仅 IP 字面量，同 OpenVPN）
|
||||||
|
l2tp_remote_port = 1701, -- 默认 1701
|
||||||
|
l2tp_username = "user", -- 可选
|
||||||
|
l2tp_password = "pass", -- 可选
|
||||||
|
l2tp_secret = nil, -- 可选，L2TP 隧道共享密钥
|
||||||
|
l2tp_mtu = 1450, -- 可选，默认 1450
|
||||||
|
l2tp_retry_enable = true, -- 可选，失败自动重连
|
||||||
|
l2tp_retry_base_ms = 1000,
|
||||||
|
l2tp_retry_max_ms = 60000,
|
||||||
|
})
|
||||||
|
-- 就绪判断沿用 netdrv.ready(id) 与 IP_READY/IP_LOSE 事件
|
||||||
|
-- netdrv.dhcp 对该网卡返回 -1（IP 由 IPCP 下发）
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 5. 测试方案
|
||||||
|
|
||||||
|
PC 模拟器 + Python mock LNS（`testcase/unit/net/netdrv_l2tp_basic/mock_lns.py`）：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# pap 场景
|
||||||
|
python testcase/unit/net/netdrv_l2tp_basic/mock_lns.py --port 1701 --auth pap --log &
|
||||||
|
LUAT_L2TP_TEST=pap build/out/luatos-lua.exe \
|
||||||
|
../../testcase/common/scripts/ ../../testcase/unit/net/netdrv_l2tp_basic/scripts/
|
||||||
|
|
||||||
|
# chap / reject / reconnect 场景分别用：
|
||||||
|
# --port 1702 --auth chap (LUAT_L2TP_TEST=chap)
|
||||||
|
# --port 1703 --reject-auth (LUAT_L2TP_TEST=reject)
|
||||||
|
# --port 1701 --drop-after 8 (LUAT_L2TP_TEST=reconnect)
|
||||||
|
```
|
||||||
|
|
||||||
|
四个场景均已实测通过（`### OVERALL_PASS ###`）：
|
||||||
|
|
||||||
|
| 场景 | 验证点 |
|
||||||
|
|---|---|
|
||||||
|
| pap | 隧道建立 + PAP 认证 + IPCP 下发 192.168.8.2 + 隧道内 TCP echo |
|
||||||
|
| chap | CHAP-MD5 认证（挑战/响应校验）+ 同样链路验证 |
|
||||||
|
| reject | 密码错误 -> 认证失败、一直 not ready |
|
||||||
|
| reconnect | 会话中途断开 -> `IP_LOSE` -> 自动重连成功 |
|
||||||
|
|
||||||
|
回归：`netdrv_evt_pkg`（19/19）、`netdrv_lwip_intercept_basic`（3/3）通过；
|
||||||
|
PC 增量编译 `Build completed successfully`，无新增告警。
|
||||||
|
|
||||||
|
### mock LNS 实现要点（实测中踩过的坑，写在这里供后续参考）
|
||||||
|
|
||||||
|
- 每端第一条控制消息 NS 从 **0** 开始（SCCRP 的 NS 必须为 0）；
|
||||||
|
- ZLB 不消耗 NS 槽位：其 NS 与下一条真实消息相同，接收方不推进 `peer_ns`；
|
||||||
|
- 数据包隧道/会话 ID 必须用**客户端分配**的 ID（lwip 按 `remote_*_id` 校验）；
|
||||||
|
- LCP/IPCP 是对称协议：服务端必须发送自己的 ConfReq，否则客户端 FSM 停在
|
||||||
|
ACKRCVD 并重传；
|
||||||
|
- LCP Echo-Reply 必须携带**服务端自己的 magic**，lwip 会拒绝携带自身 magic
|
||||||
|
的 Echo-Reply（视为回环）；
|
||||||
|
- CHAP 校验用的 secret 是 PPP 密码（客户端 `settings.passwd`），与 L2TP 隧道
|
||||||
|
`l2tp_secret` 无关；
|
||||||
|
- IPCP ConfNak 的 length 字段必须等于实际负载长度（含 DNS 选项时容易写错，
|
||||||
|
会导致客户端只解析到部分选项）。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 6. 尚待完善之处
|
||||||
|
|
||||||
|
1. **硬件 BSP 使能**：首期只落地 PC。硬件 BSP 需要确认 lwip 导出
|
||||||
|
`pbuf/netif/sys/ip4_input` 等符号；若未导出 `ip4_input`，在
|
||||||
|
`LUAT_USE_NETDRV_LWIP_ARP` 下把 vendor `ppp.c` 的调用改走
|
||||||
|
`luat_netdrv_ip4_input`。硬件侧建议在正式发布前跑一遍 mock LNS 验证。
|
||||||
|
2. **IPCP DNS 下发**：PC 当前 `LWIP_DNS=0`，`ppp.c` 的 `sdns()` 未编译，
|
||||||
|
IPCP 携带的 DNS 选项会被忽略。后续可评估启用 `LWIP_DNS` 或由驱动把
|
||||||
|
IPCP 协商出的 DNS 写入 `net_lwip2` 的 `set_dns_server`。
|
||||||
|
3. **LNS 域名支持**：`l2tp_remote_ip` 仅支持 IP 字面量；可通过传输 adapter
|
||||||
|
的 DNS 能力扩展域名解析（同 OpenVPN 现状）。
|
||||||
|
4. **隧道认证自动化测试**：`l2tp_secret` 的 Challenge/Challenge-Response
|
||||||
|
流程已实现，mock LNS 也支持 `--secret`，但当前四场景未覆盖，待补测试。
|
||||||
|
5. **认证/加密能力扩展**：MSCHAPv2、MPPE（CCP）、EAP 需要额外 vendor
|
||||||
|
`chap_ms.c/ccp.c/mppe.c/eap.c` 并调整编译选项，属后续需求。
|
||||||
|
6. **多实例**：当前按单会话设计（`MEMP_NUM_PPP_PCB=1`），多隧道/多会话、
|
||||||
|
隧道切换未支持。
|
||||||
|
7. **资源释放细节**：配置字符串（用户名/密码/密钥）在客户端生命周期内保留，
|
||||||
|
用户停止后不释放（便于再次启动）；PPP 会话若处于 `TERMINATE` 进行中，
|
||||||
|
`ppp_free` 会等待状态归位，极端时序下可能保留 pcb 等待下一次 start 清理。
|
||||||
|
8. **定时器预算**：`MEMP_NUM_SYS_TIMEOUT` 由 17 提到 24 以容纳
|
||||||
|
PPP/L2TP 的 LCP-FSM + LCP-Echo + 认证 + IPCP-FSM + L2TP 控制/周期定时器；
|
||||||
|
硬件侧若同时跑 OpenVPN/WG，需按实际固件核对预算。
|
||||||
|
9. **CI 集成**：mock LNS 依赖本机 UDP 端口，目前是手工编排；后续可封装成
|
||||||
|
CI job（起 LNS -> 跑模拟器 -> 校验 OVERALL_PASS）。
|
||||||
|
10. **文档与 API 注释**：`luat_lib_netdrv.c` 已补充 `netdrv.L2TP` 用法注释，
|
||||||
|
建议后续在 `script/` 侧补充完整 usage.md/示例。

# EC718HM/EC718PM LuatOS AT 射频校准设计规格
|
||||||
|
|
||||||
|
> 日期：2026-06-15
|
||||||
|
> 关联计划：`docs/superpowers/plans/2026-06-15-ec718hm-pm-rfa-at-plan.md`

|
|
||||||
|
## 1. 背景与目标
|
||||||
|
|
||||||
|
在 LuatOS 固件中提供一套产线 AT 指令射频校准能力，使 EC718HM/EC718PM 系列模组能够直接通过 UART 接收产线工具下发的 AT 指令完成：
|
||||||
|
- 射频校准（RFCALI）
|
||||||
|
- 非信令综测（RFNST）
|
||||||
|
- 相关产线辅助操作（IMEI 读写、NPI 标志、Golden 数据、PMU 等）
|
||||||
|
|
||||||
|
设计沿用已有的 `rfa`（Radio Factory Agent）Thin C / Fat Lua 架构，C 端只做字节搬运和状态存储，所有 AT 协议逻辑由 `script/libs/rfa.lua` 完成。
|
||||||
|
|
||||||

|
### 5.3 未实化部分
|
||||||
|
以下命令在真机目前返回占位值，需在 PLAT 侧公开对应 API 后替换：
|
||||||
|
- `AT+ECPMUCFG` 的 PMU 模式设置
|
||||||
|
- `AT+ECCHIPVER?` 的芯片版本读取
|
||||||
|
- `AT+ECBAND=?` 的支持 Band 查询
|
||||||
|
- `AT+ECFACCHK=1` 的 NV 头校验
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 6. 测试
|
||||||
|
|
||||||
|
- PC 端：`testcase/utest/drv/mobile_rfa_basic/` 4 套件 42+ case
|
||||||
|
- PC 端 com0com：`tools/rfa_com0com/test_rfa_com0com.py`
|
||||||
|
- 真机端：EC718HM/PM 开发板 + 产线工具或串口助手
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 7. 风险
|
||||||
|
|
||||||
|
1. `soc_mobile_rf_test_input` 对长 hex 字符串可能有长度限制，需与 `ATC_ECRFNST_0_STR_MAX_LEN` 对齐。
|
||||||
|
2. `AT+ECRFNST` 产线工具对响应时序敏感，需用逻辑分析仪/串口抓包对比 ec7xx-at。
|
||||||
|
3. PMU/ChipVer/Band/FACCHK 依赖未公开 PLAT API，当前为占位实现。
|
||||||
|
4. `mobile.rfTestParam` 的 `is_set` 语义在 Lua/C 边界易出错，业务代码应使用 `rfa.lua` 封装。

# EC718HM/EC718PM 系列模组 LuatOS AT 射频校准实施计划
|
||||||
|
|
||||||
|
> 基于 LuatOS rfa（Radio Factory Agent）框架，在 EC718HM/EC718PM 系列模组的 LuatOS 固件上实现产线 AT 指令射频校准功能。
|
||||||
|
> 计划日期：2026-06-15
|
||||||
|
|

|
||||||
|
|
||||||
|
## 1. 目标与范围
|
||||||
|
|
||||||
|
### 1.1 总体目标
|
||||||
|
在 LuatOS 固件中新增一个基于 rfa.lua 的 AT 服务器，通过指定 UART 接收产线校准/综测工具下发的 AT 指令，调用 mobile.rfTest* 系列 C API 与底层 RF 校准原语交互，最终使 EC718HM/EC718PM 系列模组能够用 LuatOS 固件完成产线射频校准与非信令综测。
|
||||||
|
|
||||||
|
### 1.2 覆盖命令（按 EC CAT1产线校准综测相关AT命令.xlsx）
|
||||||
|
|
||||||
|
| No. | AT Command | 属性 | 处理方式 | 备注 |
|
||||||
|
|-----|------------|------|----------|------|
|
||||||
|
| 1 | AT | 3GPP | rfa.lua 内置派发 | 握手 |
|
||||||
|
| 2 | ATE0/ATE1 | 3GPP | rfa.lua 内置派发 | 回显 |
|
||||||
|
| 3 | AT+CFUN=0 | 3GPP | rfa.lua 内置 + mobile.flymode | 进飞行模式 |
|
||||||
|
| 4 | AT+CPIN? | 3GPP | rfa.lua 内置 | 返回 CME ERROR: 303 |
|
||||||
|
| 5 | AT+CGSN | 3GPP | rfa.lua 内置 + mobile.rfTestImei | 读 IMEI |
|
||||||
|
| 6 | AT+ECPMUCFG | EigenComm | 新增 rfa.lua 处理或 C 层 mobile.rfTestParam 扩展 | PMU 模式 |
|
||||||
|
| 7 | AT+ECRST | EigenComm | 新增 rfa.lua 处理 | 软复位 |
|
||||||
|
| 8 | AT+ECCGSN | EigenComm | 新增 rfa.lua 处理 + mobile.rfTestImeiSet | 写 IMEI/SN |
|
||||||
|
| 9 | AT+ECNPICFG | EigenComm | rfa.lua 内置 + mobile.rfTestParam | 校准/综测标志位 |
|
||||||
|
| 10 | AT+ECGMDATA | EigenComm | 新增 rfa.lua 处理 + C 层扩展 | 金机数据读写 |
|
||||||
|
| 11 | AT+ECCHIPVER? | EigenComm | 新增 rfa.lua 处理或 C 层扩展 | 读芯片版本 |
|
||||||
|
| 12 | AT+ECRFNST | EigenComm | rfa.lua 私有协议派发 + mobile.rfTestInput | 校准/非信令指令 |
|
||||||
|
| 13 | AT+ECBAND=? | EigenComm | 新增 rfa.lua 处理或 C 层扩展 | 查支持 Band |
|
||||||
|
| 14 | AT+ECICCID | EigenComm | 新增 rfa.lua 处理 + mobile.* ICCID 接口 | 读 ICCID |
|
||||||
|
| 15 | AT+ECFACCHK=1 | EigenComm | 新增 rfa.lua 处理 + C 层扩展 | 查 NV 头 |
|
||||||
|
|
||||||
|
注：ECRFNST 的私有协议 cmdId 模板按产线工具需求通过 rfa.registerRfnst() 扩展；rfa.lua 默认输出占位响应。
|
||||||
|
|
||||||
|
### 1.3 不涉及范围（Non-goals）
|
||||||
|
- 不修改 ec7xx-at 现有 AT 固件实现。
|
||||||
|
- 不改动 PLAT 闭源预编译库中的 RfAtNstCmdPreHandle / RfAtTestCmd 内部逻辑。
|
||||||
|
- 不实现 ec7xx-at 中的扩展命令如 AT+ECRFTEST、AT+ECRFSTAT、AT+ECVERSION、AT+ECDIEXY 等（如需后续另开 PR）。
|
||||||
|
- 不替换现有产线工具，只保证 AT 协议层行为一致。

## 2. 现状分析
|
||||||
|
|
||||||
|
### 2.1 LuatOS 侧（框架已就绪）
|
||||||
|
- script/libs/rfa.lua：已有 7 阶段状态机、内置 AT 派发、扩展点 register / registerRfnst、UART 绑定。
|
||||||
|
- components/mobile/luat_mobile.h：已声明 6 个 luat_mobile_rf_test_* C API。
|
||||||
|
- components/mobile/luat_lib_mobile.c：已绑定 5 个 Lua API（mobile.rfTestMode/Input/Param/Imei/ImeiSet）。
|
||||||
|
- bsp/pc/port/luat_mobile_pc.c：PC 仿真后端完整实现，单元测试 testcase/utest/drv/mobile_rfa_basic/ 13 case 全过。
|
||||||
|
|
||||||
|
### 2.2 luatos-soc-2024 侧（真机后端待补齐）
|
||||||
|
- interface/src/luat_mobile_ec7xx.c 已存在：
|
||||||
|
- luat_mobile_rf_test_input()：转发到 soc_mobile_rf_test_input()，并做 toupper()。
|
||||||
|
- luat_mobile_rf_test_mode()：转发到 soc_mobile_rf_test_mode()。
|
||||||
|
- 尚未实现：
|
||||||
|
- luat_mobile_rf_test_param()：需映射到 npi_config.h 的 NPI 接口。
|
||||||
|
- luat_mobile_rf_test_imei_get()：需调用 appGetImeiNumSync()。
|
||||||
|
- luat_mobile_rf_test_imei_set()：需调用 appSetImeiNumSync()。
|
||||||
|
- luat_mobile_rf_test_set_rx_cb()：按头文件注释，真机无需实现，返回 0 或 -1 即可。
|
||||||
|
|
||||||
|
### 2.3 ec7xx-at 侧（参考实现）
|
||||||
|
- PLAT/middleware/developed/at/atps/src/atec_rf.c：AT+ECRFNST 调用 RfAtNstCmdPreHandle()。
|
||||||
|
- PLAT/middleware/developed/at/atcust/src/atec_product.c：AT+ECNPICFG、AT+ECGMDATA、AT+ECRFSTAT 等。
|
||||||
|
- PLAT/middleware/developed/at/atcust/src/atec_plat_dev.c：AT+ECPMUCFG。
|
||||||
|
- PLAT/middleware/developed/open_am/driver/src/am_service.c：soc_mobile_rf_test_mode/input 的实现入口，在闭源 libcore_airm2m.a 中。
|
||||||
|
- 关键底层头文件：
|
||||||
|
- PLAT/middleware/developed/common/inc/npi_config.h
|
||||||
|
- PLAT/middleware/developed/ecapi/psapi/inc/ps_lib_api.h
|
||||||
|
- PLAT/driver/hal/ec7xx/ap/inc/hal_rfCali.h
|
||||||
|
|
||||||

|
||||||
|
|
||||||

## 3. 架构设计
|
||||||
|
|
||||||
|
### 3.1 分层架构
|
||||||
|
|
||||||
|
```
|
||||||

|
||||||
|
|

|

| - 状态机 / NPI / IMEI 管理 |

|
| - mode/input -> soc_mobile_* |
|
||||||
|
| - param -> npi_config |
|
||||||
|
| - imei -> appGet/SetImeiNumSync |
|
||||||
|
+-----------------------------+
|
||||||
|
| soc_mobile_* / RfAtNstCmdPreHandle
|
||||||
|

|
||||||
|
+-----------------------------+
|
||||||
|
| PLAT 闭源库 / CP / PHY | <- RF 底层
|
||||||
|
+-----------------------------+
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.2 关键设计决策
|
||||||
|
|
||||||
|
1. 沿用 Thin C / Fat Lua：已有 rfa.lua 承担全部 AT 协议逻辑，C 端只做字节透传与 NPI/IMEI 读写，避免在 C 端重复实现 AT 状态机。
|
||||||
|
2. 真机端补齐 4 个 C API：param、imei_get、imei_set、set_rx_cb，其中 set_rx_cb 为无操作桩。
|
||||||
|
3. AT+ECRFNST 透传路径：
|
||||||
|
- rfa.lua 收到 AT+ECRFNST=<hex> 后，对已知 cmdId 模板生成同步响应；
|
||||||
|
- 对未知/需要底层执行的 cmdId，通过 mobile.rfTestInput() 将 hex 字节流转发给 soc_mobile_rf_test_input()，由闭源库处理并异步返回。
|
||||||
|
- 当前 rfa.lua 默认全部生成同步占位响应；若产线工具需要真响应，需按 cmdId 扩展 registerRfnst 回调。
|
||||||
|
4. PMU/Golden/ChipVer/Band/ICCID/FACCHK：
|
||||||
|
- 先尝试在 rfa.lua 中通过现有 mobile.* API（如 mobile.imei()、mobile.flymode()）实现；
|
||||||
|
- 缺少的接口优先扩展 mobile.rfTestParam 的 key 集合，由 C 层调用对应 PLAT API；
|
||||||
|
- 若 PLAT 无公开 API，则通过 mobile.rfTestInput() 走 soc_mobile_rf_test_input() 的私有通道。
|
||||||
|
5. EC718HM/EC718PM 共用同一接口文件：luat_mobile_ec7xx.c 不拆分；构建系统按 --chip_target 自动选择 PLAT/libs/ec718pm* 或 ec718hm* 预编译库。
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 4. 任务分解
|
||||||
|
|
||||||
|
### Phase 1：luatos-soc-2024 真机 C 实现
|
||||||
|
|
||||||
|
目标：补齐 luat_mobile_rf_test_param / imei_get / imei_set / set_rx_cb，使 mobile.rfTest* 在 EC718HM/PM 真机上可用。
|
||||||
|
|
||||||
|
文件：luatos-soc-2024/interface/src/luat_mobile_ec7xx.c
|
||||||
|
|
||||||
|
1. 包含必要头文件：
|
||||||
|
- PLAT/middleware/developed/common/inc/npi_config.h
|
||||||
|
- PLAT/middleware/developed/ecapi/psapi/inc/ps_lib_api.h
|
||||||
|
2. 实现 luat_mobile_rf_test_param(const char *key, int *value, int is_set)：
|
||||||
|
- key "rfCaliDone" -> NPI_PROCESS_STATUS_ITEM_RFCALI
|
||||||
|
- key "rfNSTDone" -> NPI_PROCESS_STATUS_ITEM_RFNST
|
||||||
|
- key "rfCTDone" -> NPI_PROCESS_STATUS_ITEM_RFCT
|
||||||
|
- key "state" / "erfMode" -> 本地静态变量（非持久化）
|
||||||
|
- key "save" -> 调用 npiSaveConfigToAPNV2()（确认接口名）
|
||||||
|
- 不支持的 key 返回 -1
|
||||||
|
3. 实现 luat_mobile_rf_test_imei_get(char *out, uint32_t len)：
|
||||||
|
- 调用 appGetImeiNumSync(out)，确保字符串结束。
|
||||||
|
4. 实现 luat_mobile_rf_test_imei_set(const char *imei)：
|
||||||
|
- 校验长度 15，调用 appSetImeiNumSync((char*)imei)。
|
||||||
|
5. 实现 luat_mobile_rf_test_set_rx_cb(...)：
|
||||||
|
- 真机无需，直接返回 0。
|
||||||
|
6. 编译验证：
|
||||||
|
cd luatos-soc-2024/project/example_mobile
|
||||||
|
xmake f --chip_target=ec718pm
|
||||||
|
xmake
|
||||||
|
同样对 ec718hm 做一次编译验证。
|
||||||
|
|
||||||
|
### Phase 2：LuatOS rfa.lua 扩展
|
||||||
|
|
||||||
|
目标：支持 Excel 中的 16 条核心产线命令，并保留扩展点。
|
||||||
|
|
||||||
|
文件：LuatOS/script/libs/rfa.lua
|
||||||
|
|
||||||
|
1. 在 _builtin_dispatch 中新增：
|
||||||
|
- AT+ECRST -> 调用 mobile.restart() 或 mobile.rfTestInput 私有通道；返回 OK 后触发复位。
|
||||||
|
- AT+ECCGSN=<type>,<sn/imei> -> 校验类型与长度，调用 mobile.rfTestImeiSet()。
|
||||||
|
- AT+ECGMDATA? -> 返回 Golden Unit 数据（先返回 OK 占位，后续接 Phase 4）。
|
||||||
|
- AT+ECGMDATA=<data> -> 写入 Golden Unit 数据。
|
||||||
|
- AT+ECCHIPVER? -> 返回芯片版本字符串。
|
||||||
|
- AT+ECBAND=? -> 返回支持的 Band 列表。
|
||||||
|
- AT+ECICCID -> 调用 mobile.iccid() 或等效 API。
|
||||||
|
- AT+ECPMUCFG=<enable>[,<mode>] -> 设置 PMU 模式。
|
||||||
|
- AT+ECPMUCFG? -> 查询 PMU 模式。
|
||||||
|
- AT+ECFACCHK=1 -> 返回 NV 头校验结果。
|
||||||
|
2. 对 AT+ECRFNST 处理增强：
|
||||||
|
- 保留默认占位响应；
|
||||||
|
- 增加常见 cmdId（如 0x0D、0x0A、0x51-0x5A）的模板响应；
|
||||||
|
- 提供 rfa.registerRfnst() 让项目级 Lua 代码注入更多模板。
|
||||||
|
3. 添加 rfa.atServerStart(id, baud) 别名（与 rfa.start 等价），便于产线工具文档对齐。
|
||||||
|
|
||||||
|
### Phase 3：LuatOS C 绑定修正（如需要）
|
||||||
|
|
||||||
|
文件：LuatOS/components/mobile/luat_lib_mobile.c
|
||||||
|
|
||||||
|
1. 检查 l_mobile_rf_test_param 的 is_set 参数处理：当前 lua_toboolean(L, 4) 对整数 0 判断为 true，需确认 rfa.lua 已用 nil/false 表示读；如需更健壮，可改为显式判断 lua_isnil/lua_isboolean。
|
||||||
|
2. 检查 LUAT_USE_MOBILE_RFA 宏在目标 BSP（如 bsp/ec7xx）中是否已打开；未打开则添加。
|
||||||
|
|
||||||
|
### Phase 4：Golden / PMU / ChipVer / Band / ICCID / FACCHK 的 C 后端（按需）
|
||||||
|
|
||||||
|
目标：若 rfa.lua 缺少对应 mobile.* API，则通过扩展 mobile.rfTestParam 或新增 C API 实现。
|
||||||
|
|
||||||
|
文件：
|
||||||
|
- LuatOS/components/mobile/luat_mobile.h（仅当新增 API 时）
|
||||||
|
- LuatOS/components/mobile/luat_lib_mobile.c
|
||||||
|
- luatos-soc-2024/interface/src/luat_mobile_ec7xx.c
|
||||||
|
|
||||||
|
1. AT+ECGMDATA：
|
||||||
|
- 方案 A：通过 mobile.rfTestParam 新增 key "gmData"（读写 int 数组或字符串长度受限）。
|
||||||
|
- 方案 B：新增 mobile.rfTestGmData(buf) / mobile.rfTestGmDataSet(buf) 字符串 API。
|
||||||
|
- 推荐方案 B，因为 Golden 数据可能较长。
|
||||||
|
2. AT+ECPMUCFG：
|
||||||
|
- 新增 mobile.rfTestParam key "pmuMode" / "pmuEnable"，C 层调用 apmuSetDeepestSleepMode() 或 PMU_SetSleepMode()。
|
||||||
|
3. AT+ECCHIPVER?：
|
||||||
|
- 新增 mobile.rfTestParam key "chipVer"，C 层调用现有 chipver API。
|
||||||
|
4. AT+ECBAND=?：
|
||||||
|
- 新增 mobile.rfTestParam key "bandList"，C 层返回支持的 Band 位图。
|
||||||
|
5. AT+ECICCID：
|
||||||
|
- 优先复用 mobile.iccid()；若不可用，新增 mobile.rfTestIccid()。
|
||||||
|
6. AT+ECFACCHK=1：
|
||||||
|
- 新增 mobile.rfTestParam key "facChk"，C 层调用 NV 头校验接口。
|
||||||
|
|
||||||
|
Phase 4 的具体命令可在进入开发后根据产线工具实际交互日志裁剪；本计划按“全部实现”排期。
|
||||||
|
|
||||||
|
### Phase 5：单元测试与集成测试
|
||||||
|
|
||||||
|
文件：
|
||||||
|
- LuatOS/testcase/utest/drv/mobile_rfa_basic/scripts/mobile_rfa_test.lua
|
||||||
|
- LuatOS/tools/rfa_com0com/test_rfa_com0com.py
|
||||||
|
- 新增：testcase/utest/drv/mobile_rfa_basic/scripts/ec718_rfa_test.lua（真机行为 mock）
|
||||||
|
|
||||||
|
1. PC 端单元测试：
|
||||||
|
- 扩展 mobile_rfa_test.lua，覆盖新增命令（ECRST、ECCGSN、ECGMDATA、ECPMUCFG、ECBAND、ECICCID、ECFACCHK、ECCHIPVER）。
|
||||||
|
- 验证状态机推进、IMEI 读写、NPI 保存。
|
||||||
|
2. PC 端 com0com 回归：
|
||||||
|
- 扩展 test_rfa_com0com.py，覆盖 Excel 中的核心命令。
|
||||||
|
3. 真机测试：
|
||||||
|
- 在 EC718HM/PM 开发板上烧录 LuatOS 固件。
|
||||||
|
- 使用 USB/UART 连接产线工具或串口助手，验证：
|
||||||
|
- 握手与回显
|
||||||
|
- CFUN=0 进入飞行模式
|
||||||
|
- CGSN 读 IMEI
|
||||||
|
- ECCGSN 写 IMEI
|
||||||
|
- ECGMDATA 读写
|
||||||
|
- ECRFNST 私有协议响应
|
||||||
|
- ECNPICFG 标志位读写与掉电保持
|
||||||
|
- ECRST 复位
|
||||||
|
4. 产线工具对齐：
|
||||||
|
- 用实际产线工具跑一遍校准/综测流程，对比 ec7xx-at 输出行为差异并修复。
|
||||||
|
|
||||||
|
### Phase 6：文档与落档
|
||||||

## 6. 风险与应对
|
||||||
|
|
||||||
|
| 风险 | 影响 | 应对 |
|
||||||
|
|------|------|------|
|
||||||
|
| npi_config.h / appGetImeiNumSync 在 ec718hm 与 ec718pm 上行为不一致 | 中 | 在两个目标上分别编译并真机验证；若 API 有差异，用宏隔离 |
|
||||||
|
| soc_mobile_rf_test_input 对长 hex 字符串（>8000 字符）有长度限制 | 中 | 与 ec7xx-at 中 ATC_ECRFNST_0_STR_MAX_LEN 对齐；超长时分片或报错 |
|
||||||
|
| AT+ECGMDATA 需要文件系统（LittleFS）支持，LuatOS 真机文件路径不同 | 中 | 复用 LuatOS io/fs API 而非直接写 /rfTestFile；PC 端用内存缓冲 |
|

|
## 各 FS 详细结果
|
||||||
|
|
||||||
|
### ram — 30/30 PASS ✅
|
||||||
|
参考实现, 所有用例都通过. 验证了 30 个用例在 VFS 统一接口下的预期行为.
|
||||||
|
|
||||||
|
### posix — 27/30 PASS, 3 bugs
|
||||||
|
1. **test_dir_nested_mkdir_auto_parent** [med] — `io.mkdir("a/b/c")` 父目录不存在时失败 (单 `mkdir` 调用, 不递归)
|
||||||
|
2. **test_edge_deep_nesting** [low] — 7 级嵌套 mkdir 失败 (同上根因)
|
||||||
|
3. **test_meta_rename_overwrite** [low] — Windows `rename` 不允许覆盖已存在目标
|
||||||
|
|
||||||
|
### lfs2 — 26/30 PASS, 4 bugs
|
||||||
|
跳过 1 个 (test_dir_nested_mkdir_auto_parent, C13 已知不兼容):
|
||||||
|
1. **test_edge_long_filename** [low] — 60 字符文件名失败
|
||||||
|
2. **test_edge_deep_nesting** [low] — 7 级嵌套 mkdir 失败
|
||||||
|
3. **test_refcount_remove_open_fails** [med] — 打开中的文件可被 os.remove 删除
|
||||||
|
4. **test_refcount_rename_open_fails** [med] — 打开中的文件可被 os.rename 重命名
|
||||||
|
|
||||||
|
**关键发现**: lfs2 不实现 POSIX 引用计数, 直接转发 `lfs_remove` / `lfs_rename`.
|
||||||
|
|
||||||
|
### fatfs — 30/30 (修复完成, 本轮)
|
||||||
|
**本轮修复**:
|
||||||
|
- `bsp/pc/xmake.lua` 新增 `add_defines("LUAT_USE_FATFS=1")` 与 `LUAT_USE_FS_VFS=1`,
|
||||||
|
让 `luaopen_fatfs` 在 PC BSP 注册, `luat_fs_fatfs.c` 编译进 VFS 适配.
|
||||||
|
- `mount_fatfs.lua` 加 TDD 探针 (`require("fatfs")` 不抛 + `fatfs.mount(fatfs.SPI, "/fatfs", 20, 23, ...)` 成功),
|
||||||
|
复用 PC 现有的 `pc_vsd_t` 虚拟 SD 卡 (bus 20 / CS 23, 64MB 镜像 `spidrv/tf.bin`).
|
||||||
|
|
||||||
|
原 2 个 high bug (`require` 抛错 + 模块未注册) 已修, 0/30 → 30/30.
|
||||||
|
|
||||||
|
### tfs — 30/30 (修复完成, 本轮)
|
||||||
|
**本轮修复**:
|
||||||
|
- `mount_tfs.lua` 把 256KB 测试分区升到 16MB (TFS OOB + name marker + 初始 CP 至少需要数 MB).
|
||||||
|
16MB 与 PGFS 16MB 静态 slab (s_pgfs_test_flash_slab) 策略一致.
|
||||||
|
- 新增 `tdd_probe_tfs_mounted()`: 挂载后立刻 `io.open("/tfs0/_vfs_uniform_probe", "wb")` 探活,
|
||||||
|
PASS/FAIL 仅日志不阻断 setup, 与 PGFS probe 模式一致.
|
||||||
|
|
||||||
|
源: `components/little_flash/luat_little_flash_tfs.c:478` name marker 已在 fresh mount 上自动 format
|
||||||
|
fallback (line 1286 `lf_tfs_format_and_mount`), 分区扩大后 mount 链不再早退.
|
||||||
|
|
||||||
|
原 2 个 high bug (name marker open fails + 30 用例全 skip) 已修, 0/30 → 30/30.
|
||||||
|
|
||||||
|
### pgfs — 28/30 PASS, 2 bugs (修复完成, 本轮)
|
||||||
|
跳过 2 个 (test_dir_rmdir_nonempty_fails, test_dir_nested_mkdir_auto_parent).
|
||||||
|
|
||||||
|
**本轮修复**:
|
||||||
|
- `components/pgfs/pgfs_internal.h` 新增 `PGFS_MIN_PARTITION_BYTES = 8MB` 常量,
|
||||||
|
附详细 budget 注释 (FTL 元数据 ~256KB + 2× superblock + 2× CP + 64×128KB 段).
|
||||||
|
- `components/pgfs/pgfs_vfs_adapter.c:luat_vfs_pgfs_mount` 在 mount 早期加 size gate,
|
||||||
|
< 8MB 直接 `LLOGE` + 返回 -1.
|
||||||
|
- `mount_pgfs.lua` 加 3 个 TDD probe (256KB 拒绝 / 8MB 接受 / 16MB 接受),
|
||||||
|
并把实际挂载分区从 256KB 切到 16MB (与 `s_pgfs_test_flash_slab` 一致).
|
||||||
|
|
||||||
|
**仅剩 bug** (2, 均不属本轮):
|
||||||
|
1. **test_refcount_remove_open_fails** [med] — 同 lfs2, 不检查引用
|
||||||
|
2. **test_meta_rename_overwrite** [low] — rename 不允许覆盖目标
|
||||||
|
|
||||||
|
**FTL "no free blocks" 12 个衍生症状已全部消除** (16/30 → 28/30), 写不再静默丢失数据.
|
||||||
|
|
||||||
|
## 跨 FS 对比 (关键发现)
|
||||||
|
|
||||||
|
### POSIX 行为分歧
|
||||||
|
|
||||||
|
| 用例 | ram | posix | lfs2 | pgfs | 期望 |
|
||||||
|
|------|-----|-------|------|------|------|
|
||||||
|
| rmdir 非空目录 | ✅ 拒绝 | ✅ 拒绝 | ❌ 允许 | (skip) | 拒绝 |
|
||||||
|
| remove open file | ✅ 拒绝 | ❌ 允许 | ❌ 允许 | ❌ 允许 | 拒绝 |
|
||||||
|
| rename open src | ✅ 拒绝 | ❌ 允许 | ❌ 允许 | ❌ 允许 | 拒绝 |
|
||||||
|
| rename 覆盖目标 | ✅ 允许 | ❌ 拒绝 | ✅ 允许 | ❌ 拒绝 | 允许 |
|
||||||
|
| mkdir 嵌套父目录 | ✅ 允许 | ❌ 拒绝 | ❌ 拒绝 | (skip) | 允许 |
|
||||||
|
|
||||||
|
### 数据丢失 (高严重度)
|
||||||
|
|
||||||
|
- ~~**pgfs**: 在小分区上 FTL 段分配失败, 写静默丢失数据 (12 个用例受影响)~~ — 本轮已修
|
||||||
|
- ~~**fatfs / tfs**: 在 PC 上根本跑不通, 无法评估数据完整性~~ — 本轮已修
|
||||||
|
|
||||||
|
## 框架改进 (在 vfs-utest 期间发现)
|
||||||
|
|
||||||
|
- LuatOS 的 `f:seek(whence, offset)` 是 Lua 标准形式, 不是 `f:seek(offset, whence)`
|
||||||
|
- LuatOS 没有 `f:tell()`, 用 `f:seek()` (无参) 获取当前位置
|
||||||
|
- LuatOS 的 `io.exists()` 只检查文件, 不检查目录 (用 `io.lsdir` 验证目录)
|
||||||
|
- LuatOS 的 `f:read()` 在 closed file 上调用会失败 (PC 是 error)
|
||||||
|
- `io.mkdir` 在不同 FS 上对父目录缺失的容忍度不同 (ram 自动创建, 其他需要先 mkdir 父)
|
||||||
|
|
||||||
|

|
## 下一步
|
||||||
|
|
||||||
|
1. ~~修复 pgfs 的 FTL "no free blocks" 问题 (优先级 high)~~ — 本轮已修 (commit `19e49d586`)
|
||||||
|
2. ~~修复 tfs mount 的 name marker 问题 (luat_little_flash_tfs.c:478)~~ — 本轮已修 (commit `90267fbbc`)
|
||||||
|
3. ~~修复 fatfs 在 PC BSP 上的模块加载 (luat_base_mini.c 实际未注册)~~ — 本轮已修
|
||||||
|
- 主分支 commit `419030781` (require 风格探针) → 修订版在
|
||||||
|
`.worktrees/fix-fatfs-pc-mount` 上的 `9c300b19e` (LuatOS 约定:基础 C
|
||||||
|
模块走全局, 不 require; 参考 `spitf_test.lua:13`)
|
||||||
|
- 修订版需要把 `419030781` 替换/移除, 历史清理待协调
|
||||||
|
4. 修复 lfs2 的 refcount 缺失 (在 luat_fs_lfs2.c:134 加引用检查) — MED, 排期中
|
||||||
|
5. 修复 pgfs 的 refcount 缺失 (pgfs 同 lfs2) — MED, 排期中
|
||||||
|
6. 评估 posix 在 Linux/macOS 上的语义 (Windows rename 不能覆盖是 OS 行为)

We assume that instructions are unsigned numbers.
|
||||||
|
All instructions have an opcode in the first 6 bits.
|

|
Instructions can have the following fields:
|
||||||
|
'A' : 8 bits
|
||||||
|
'B' : 9 bits
|
||||||
|
'C' : 9 bits
|
||||||
|
'Ax' : 26 bits ('A', 'B', and 'C' together)
|
||||||
|
'Bx' : 18 bits ('B' and 'C' together)
|
||||||
|
'sBx' : signed Bx
|
||||||
|
|
||||||
|
A signed argument is represented in excess K; that is, the number
|
||||||
|
value is the unsigned value minus K. K is exactly the maximum value
|
||||||
|
for that argument (so that -max is represented by 0, and +max is
|
||||||
|
represented by 2*max), which is half the maximum for the corresponding
|

|
unsigned argument.

Notes:
|
||||||
|
(*) In OP_CALL, if (B == 0) then B = top. If (C == 0), then 'top' is
|
||||||
|
set to last_result+1, so next open instruction (OP_CALL, OP_RETURN,
|
||||||
|
OP_SETLIST) may use 'top'.
|
||||||
|
|
||||||
|
(*) In OP_VARARG, if (B == 0) then use actual number of varargs and
|
||||||
|
set top (like in OP_CALL with C == 0).
|
||||||
|
|
||||||
|
(*) In OP_RETURN, if (B == 0) then return up to 'top'.
|
||||||
|
|
||||||
|
(*) In OP_SETLIST, if (B == 0) then B = 'top'; if (C == 0) then next
|
||||||
|
'instruction' is EXTRAARG(real C).
|
||||||
|
|
||||||
|
(*) In OP_LOADKX, the next 'instruction' is always EXTRAARG.
|
||||||
|
|
||||||
|
(*) For comparisons, A specifies what condition the test should accept
|
||||||
|
(true or false).
|
||||||
|
|
||||||
|
(*) All 'skips' (pc++) assume that next instruction is a jump.

|
Designed and implemented in April of 1972 by John Walker, based on the
|
||||||
|
Case Algol OPRO$ algorithm implemented in 1966.
|
||||||
|
|
||||||
|
Reimplemented in 1975 by John Walker for the Interdata 70.
|
||||||
|
Reimplemented in 1977 by John Walker for the Marinchip 9900.
|
||||||
|
Reimplemented in 1982 by Duff Kurland for the Intel 8080.
|
||||||
|
|
||||||
|
Portable C version implemented in September of 1990 by an older, wiser
|
||||||
|
instance of the original implementor.
|

INTRODUCTION
|
||||||
|
============
|
||||||
|
|
||||||
|
BGET is a comprehensive memory allocation package which is easily
|
||||||
|
configured to the needs of an application. BGET is efficient in
|
||||||
|
both the time needed to allocate and release buffers and in the
|
||||||
|
memory overhead required for buffer pool management. It
|
||||||
|
automatically consolidates contiguous space to minimise
|
||||||
|
fragmentation. BGET is configured by compile-time definitions,
|
||||||
|
Major options include:
|
||||||
|
|
||||||
|
* A built-in test program to exercise BGET and
|
||||||
|
demonstrate how the various functions are used.
|
||||||
|
|
||||||
|
* Allocation by either the "first fit" or "best fit"
|
||||||
|
method.
|
||||||
|
|
||||||
|
* Wiping buffers at release time to catch code which
|
||||||
|
references previously released storage.
|
||||||
|
|
||||||
|
* Built-in routines to dump individual buffers or the
|
||||||
|
entire buffer pool.
|
||||||
|
|
||||||
|
* Retrieval of allocation and pool size statistics.
|
||||||
|
|
||||||
|
* Quantisation of buffer sizes to a power of two to
|
||||||
|
satisfy hardware alignment constraints.
|
||||||
|
|
||||||
|
* Automatic pool compaction, growth, and shrinkage by
|
||||||
|
means of call-backs to user defined functions.
|
||||||
|
|
||||||
|
Applications of BGET can range from storage management in
|
||||||
|
ROM-based embedded programs to providing the framework upon which
|
||||||
|
a multitasking system incorporating garbage collection is
|
||||||
|
constructed. BGET incorporates extensive internal consistency
|
||||||
|
checking using the <assert.h> mechanism; all these checks can be
|
||||||
|
turned off by compiling with NDEBUG defined, yielding a version of
|
||||||
|
BGET with minimal size and maximum speed.
|
||||||
|
|
||||||
|
The basic algorithm underlying BGET has withstood the test of
|
||||||
|
time; more than 25 years have passed since the first
|
||||||
|
implementation of this code. And yet, it is substantially more
|
||||||
|
efficient than the native allocation schemes of many operating
|
||||||
|
systems: the Macintosh and Microsoft Windows to name two, on which
|
||||||
|
programs have obtained substantial speed-ups by layering BGET as
|
||||||
|
an application level memory manager atop the underlying system's.
|
||||||
|
|
||||||
|
BGET has been implemented on the largest mainframes and the lowest
|
||||||
|
of microprocessors. It has served as the core for multitasking
|
||||||
|
operating systems, multi-thread applications, embedded software in
|
||||||
|
data network switching processors, and a host of C programs. And
|
||||||
|
while it has accreted flexibility and additional options over the
|
||||||
|
years, it remains fast, memory efficient, portable, and easy to
|
||||||
|
integrate into your program.
|
||||||
|
|
||||||
|
|
||||||
|
BGET IMPLEMENTATION ASSUMPTIONS
|
||||||
|
===============================
|
||||||
|
|
||||||
|
BGET is written in as portable a dialect of C as possible. The
|
||||||
|
only fundamental assumption about the underlying hardware
|
||||||
|
architecture is that memory is allocated is a linear array which
|
||||||
|
can be addressed as a vector of C "char" objects. On segmented
|
||||||
|
address space architectures, this generally means that BGET should
|
||||||
|
be used to allocate storage within a single segment (although some
|
||||||
|
compilers simulate linear address spaces on segmented
|
||||||
|
architectures). On segmented architectures, then, BGET buffer
|
||||||
|
pools may not be larger than a segment, but since BGET allows any
|
||||||
|
number of separate buffer pools, there is no limit on the total
|
||||||
|
storage which can be managed, only on the largest individual
|
||||||
|
object which can be allocated. Machines with a linear address
|
||||||
|
architecture, such as the VAX, 680x0, Sparc, MIPS, or the Intel
|
||||||
|
80386 and above in native mode, may use BGET without restriction.
|
||||||
|
|
||||||
|
|
||||||
|
GETTING STARTED WITH BGET
|
||||||
|
=========================
|
||||||
|
|
||||||
|
Although BGET can be configured in a multitude of fashions, there
|
||||||
|
are three basic ways of working with BGET. The functions
|
||||||
|
mentioned below are documented in the following section. Please
|
||||||
|
excuse the forward references which are made in the interest of
|
||||||
|
providing a roadmap to guide you to the BGET functions you're
|
||||||
|
likely to need.
|
||||||
|
|
||||||
|
Embedded Applications
|
||||||
|
---------------------
|
||||||
|
|
||||||
|
Embedded applications typically have a fixed area of memory
|
||||||
|
dedicated to buffer allocation (often in a separate RAM address
|
||||||
|
space distinct from the ROM that contains the executable code).
|
||||||
|
To use BGET in such an environment, simply call bpool() with the
|
||||||
|
start address and length of the buffer pool area in RAM, then
|
||||||
|
allocate buffers with bget() and release them with brel().
|
||||||
|
Embedded applications with very limited RAM but abundant CPU speed
|
||||||
|
may benefit by configuring BGET for BestFit allocation (which is
|
||||||
|
usually not worth it in other environments).
|
||||||
|
|
||||||
|
Malloc() Emulation
|
||||||
|
------------------
|
||||||
|
|
||||||
|
If the C library malloc() function is too slow, not present in
|
||||||
|
your development environment (for example, an a native Windows or
|
||||||
|
Macintosh program), or otherwise unsuitable, you can replace it
|
||||||
|
with BGET. Initially define a buffer pool of an appropriate size
|
||||||
|
with bpool()--usually obtained by making a call to the operating
|
||||||
|
system's low-level memory allocator. Then allocate buffers with
|
||||||
|
bget(), bgetz(), and bgetr() (the last two permit the allocation
|
||||||
|
of buffers initialised to zero and [inefficient] re-allocation of
|
||||||
|
existing buffers for compatibility with C library functions).
|
||||||
|
Release buffers by calling brel(). If a buffer allocation request
|
||||||
|
fails, obtain more storage from the underlying operating system,
|
||||||
|
add it to the buffer pool by another call to bpool(), and continue
|
||||||
|
execution.
|
||||||
|
|
||||||
|
Automatic Storage Management
|
||||||
|
----------------------------
|
||||||
|
|
||||||
|
You can use BGET as your application's native memory manager and
|
||||||
|
implement automatic storage pool expansion, contraction, and
|
||||||
|
optionally application-specific memory compaction by compiling
|
||||||
|
BGET with the BECtl variable defined, then calling bectl() and
|
||||||
|
supplying functions for storage compaction, acquisition, and
|
||||||
|
release, as well as a standard pool expansion increment. All of
|
||||||
|
these functions are optional (although it doesn't make much sense
|
||||||
|
to provide a release function without an acquisition function,
|
||||||
|
does it?). Once the call-back functions have been defined with
|
||||||
|
bectl(), you simply use bget() and brel() to allocate and release
|
||||||
|
storage as before. You can supply an initial buffer pool with
|
||||||
|
bpool() or rely on automatic allocation to acquire the entire
|
||||||
|
pool. When a call on bget() cannot be satisfied, BGET first
|
||||||
|
checks if a compaction function has been supplied. If so, it is
|
||||||
|
called (with the space required to satisfy the allocation request
|
||||||
|
and a sequence number to allow the compaction routine to be called
|
||||||
|
successively without looping). If the compaction function is able
|
||||||
|
to free any storage (it needn't know whether the storage it freed
|
||||||
|
was adequate) it should return a nonzero value, whereupon BGET
|
||||||
|
will retry the allocation request and, if it fails again, call the
|
||||||
|
compaction function again with the next-higher sequence number.
|
||||||
|
|
||||||
|
If the compaction function returns zero, indicating failure to
|
||||||
|
free space, or no compaction function is defined, BGET next tests
|
||||||
|
whether a non-NULL allocation function was supplied to bectl().
|
||||||
|
If so, that function is called with an argument indicating how
|
||||||
|
many bytes of additional space are required. This will be the
|
||||||
|
standard pool expansion increment supplied in the call to bectl()
|
||||||
|
unless the original bget() call requested a buffer larger than
|
||||||
|
this; buffers larger than the standard pool block can be managed
|
||||||
|
"off the books" by BGET in this mode. If the allocation function
|
||||||
|
succeeds in obtaining the storage, it returns a pointer to the new
|
||||||
|
block and BGET expands the buffer pool; if it fails, the
|
||||||
|
allocation request fails and returns NULL to the caller. If a
|
||||||
|
non-NULL release function is supplied, expansion blocks which
|
||||||
|
become totally empty are released to the global free pool by
|
||||||
|
passing their addresses to the release function.
|
||||||
|
|
||||||
|
Equipped with appropriate allocation, release, and compaction
|
||||||
|
functions, BGET can be used as part of very sophisticated memory
|
||||||
|
management strategies, including garbage collection. (Note,
|
||||||
|
however, that BGET is *not* a garbage collector by itself, and
|
||||||
|
that developing such a system requires much additional logic and
|
||||||
|
careful design of the application's memory allocation strategy.)

BGET FUNCTION DESCRIPTIONS
|
||||||
|
==========================
|
||||||
|
|
||||||
|
Functions implemented in this file (some are enabled by certain of
|
||||||
|
the optional settings below):
|
||||||
|
|
||||||
|
void bpool(void *buffer, bufsize len);
|
||||||
|
|
||||||
|
Create a buffer pool of <len> bytes, using the storage starting at
|
||||||
|
<buffer>. You can call bpool() subsequently to contribute
|
||||||
|
additional storage to the overall buffer pool.
|
||||||
|
|
||||||
|
void *bget(bufsize size);
|
||||||
|
|
||||||
|
Allocate a buffer of <size> bytes. The address of the buffer is
|
||||||
|
returned, or NULL if insufficient memory was available to allocate
|
||||||
|
the buffer.
|
||||||
|
|
||||||
|
void *bgetz(bufsize size);
|
||||||
|
|
||||||
|
Allocate a buffer of <size> bytes and clear it to all zeroes. The
|
||||||
|
address of the buffer is returned, or NULL if insufficient memory
|
||||||
|
was available to allocate the buffer.
|
||||||
|
|
||||||
|
void *bgetr(void *buffer, bufsize newsize);
|
||||||
|
|
||||||
|
Reallocate a buffer previously allocated by bget(), changing its
|
||||||
|
size to <newsize> and preserving all existing data. NULL is
|
||||||
|
returned if insufficient memory is available to reallocate the
|
||||||
|
buffer, in which case the original buffer remains intact.
|
||||||
|
|
||||||
|
void brel(void *buf);
|
||||||
|
|
||||||
|
Return the buffer <buf>, previously allocated by bget(), to the
|
||||||
|
free space pool.
|
||||||
|
|
||||||
|
void bectl(int (*compact)(bufsize sizereq, int sequence),
|
||||||
|
void *(*acquire)(bufsize size),
|
||||||
|
void (*release)(void *buf),
|
||||||
|
bufsize pool_incr);
|
||||||
|
|
||||||
|
Expansion control: specify functions through which the package may
|
||||||
|
compact storage (or take other appropriate action) when an
|
||||||
|
allocation request fails, and optionally automatically acquire
|
||||||
|
storage for expansion blocks when necessary, and release such
|
||||||
|
blocks when they become empty. If <compact> is non-NULL, whenever
|
||||||
|
a buffer allocation request fails, the <compact> function will be
|
||||||
|
called with arguments specifying the number of bytes (total buffer
|
||||||
|
size, including header overhead) required to satisfy the
|
||||||
|
allocation request, and a sequence number indicating the number of
|
||||||
|
consecutive calls on <compact> attempting to satisfy this
|
||||||
|
allocation request. The sequence number is 1 for the first call
|
||||||
|
on <compact> for a given allocation request, and increments on
|
||||||
|
subsequent calls, permitting the <compact> function to take
|
||||||
|
increasingly dire measures in an attempt to free up storage. If
|
||||||
|
the <compact> function returns a nonzero value, the allocation
|
||||||
|
attempt is re-tried. If <compact> returns 0 (as it must if it
|
||||||
|
isn't able to release any space or add storage to the buffer
|
||||||
|
pool), the allocation request fails, which can trigger automatic
|
||||||
|
pool expansion if the <acquire> argument is non-NULL. At the time
|
||||||
|
the <compact> function is called, the state of the buffer
|
||||||
|
allocator is identical to that at the moment the allocation
|
||||||
|
request was made; consequently, the <compact> function may call
|
||||||
|
brel(), bpool(), bstats(), and/or directly manipulate the buffer
|
||||||
|
pool in any manner which would be valid were the application in
|
||||||
|
control. This does not, however, relieve the <compact> function
|
||||||
|
of the need to ensure that whatever actions it takes do not change
|
||||||
|
things underneath the application that made the allocation
|
||||||
|
request. For example, a <compact> function that released a buffer
|
||||||
|
in the process of being reallocated with bgetr() would lead to
|
||||||
|
disaster. Implementing a safe and effective <compact> mechanism
|
||||||
|
requires careful design of an application's memory architecture,
|
||||||
|
and cannot generally be easily retrofitted into existing code.
|
||||||
|
|
||||||
|
If <acquire> is non-NULL, that function will be called whenever an
|
||||||
|
allocation request fails. If the <acquire> function succeeds in
|
||||||
|
allocating the requested space and returns a pointer to the new
|
||||||
|
area, allocation will proceed using the expanded buffer pool. If
|
||||||
|
<acquire> cannot obtain the requested space, it should return NULL
|
||||||
|
and the entire allocation process will fail. <pool_incr>
|
||||||
|
specifies the normal expansion block size. Providing an <acquire>
|
||||||
|
function will cause subsequent bget() requests for buffers too
|
||||||
|
large to be managed in the linked-block scheme (in other words,
|
||||||
|
larger than <pool_incr> minus the buffer overhead) to be satisfied
|
||||||
|
directly by calls to the <acquire> function. Automatic release of
|
||||||
|
empty pool blocks will occur only if all pool blocks in the system
|
||||||
|
are the size given by <pool_incr>.
|
||||||
|
|
||||||
|
void bstats(bufsize *curalloc, bufsize *totfree,
|
||||||
|
bufsize *maxfree, unsigned long *nget, unsigned long *nrel);
|
||||||
|
|
||||||
|
The amount of space currently allocated is stored into the
|
||||||
|
variable pointed to by <curalloc>. The total free space (sum of
|
||||||
|
all free blocks in the pool) is stored into the variable pointed
|
||||||
|
to by <totfree>, and the size of the largest single block in the
|
||||||
|
free space pool is stored into the variable pointed to by
|
||||||
|
<maxfree>. The variables pointed to by <nget> and <nrel> are
|
||||||
|
filled, respectively, with the number of successful (non-NULL
|
||||||
|
return) bget() calls and the number of brel() calls.
|
||||||
|
|
||||||
|
void bstatse(bufsize *pool_incr, unsigned long *npool,
|
||||||
|
unsigned long *npget, unsigned long *nprel,
|
||||||
|
unsigned long *ndget, unsigned long *ndrel);
|
||||||
|
|
||||||
|
Extended statistics: The expansion block size will be stored into
|
||||||
|
the variable pointed to by <pool_incr>, or the negative thereof if
|
||||||
|
automatic expansion block releases are disabled. The number of
|
||||||
|
currently active pool blocks will be stored into the variable
|
||||||
|
pointed to by <npool>. The variables pointed to by <npget> and
|
||||||
|
<nprel> will be filled with, respectively, the number of expansion
|
||||||
|
block acquisitions and releases which have occurred. The
|
||||||
|
variables pointed to by <ndget> and <ndrel> will be filled with
|
||||||
|
the number of bget() and brel() calls, respectively, managed
|
||||||
|
through blocks directly allocated by the acquisition and release
|
||||||
|
functions.
|
||||||
|
|
||||||
|
void bufdump(void *buf);
|
||||||
|
|
||||||
|
The buffer pointed to by <buf> is dumped on standard output.
|
||||||
|
|
||||||
|
void bpoold(void *pool, int dumpalloc, int dumpfree);
|
||||||
|
|
||||||
|
All buffers in the buffer pool <pool>, previously initialised by a
|
||||||
|
call on bpool(), are listed in ascending memory address order. If
|
||||||
|
<dumpalloc> is nonzero, the contents of allocated buffers are
|
||||||
|
dumped; if <dumpfree> is nonzero, the contents of free blocks are
|
||||||
|
dumped.
|
||||||
|
|
||||||
|
int bpoolv(void *pool);
|
||||||
|
|
||||||
|
The named buffer pool, previously initialised by a call on
|
||||||
|
bpool(), is validated for bad pointers, overwritten data, etc. If
|
||||||
|
compiled with NDEBUG not defined, any error generates an assertion
|
||||||
|
failure. Otherwise 1 is returned if the pool is valid, 0 if an
|
||||||
|
error is found.

本demo主要使用AirCAMERA_1040 gc032a摄像头完成拍照上传任务
|
||||||
|
Air780EPM的sys ram内存资源只有2.3M，在使用camera功能时，需要非常谨慎，避免内存泄漏导致系统崩溃，需要注意以下情况：
|
||||||
|
1、exmcamera业务执行时，必须要确保有连续的内存空间，否则会导致excamera.open()初始化失败，需要的空间计算方式为：
|
||||||
|
（ 摄像头像素高 X 摄像头像素宽 X 2 ），用“GC032A”举例，内存空间为：640 * 480 * 2 = 614400 (B) ≈ 620KB
|
||||||
|
2、当使用ZBUFF方式存储照片，或者将照片放到 /ram/ 路径下保存时，必须确保有更多的内存连续空间，需要的总空间大小计算方式为：
|
||||||
|
（ 摄像头像素高 X 摄像头像素宽 X 3.5 ），用“GC032A”举例，内存空间为：640 * 480 * 3.5 = 1075200 (B) ≈ 1MB
|

3、本DEMO为常规模式下，摄像头稳定供电使用，DEMO逻辑为excamera.open()初始化完摄像头后，只需要重复调用excamera.photo()拍照即可，不需要反复的初始化关闭摄像头；
|
||||||
|
4、在实际应用中，务必将摄像头初始化的优先级排前，因为摄像头业务占用内存过大，尽早的初始化可以确保摄像头初始化时拿到足够的连续内存，确保后续拍照时能够正常执行；
|
||||||
|
5、Air780EPM的内存非常有限，在摄像头需求高的产品设计中，请选择Air780EHM/EGH/EHV、Air8000、Air700ECH这类 8MB + 8MB 的SOC，更大的内存才是摄像头业务稳定运行的最优解；
|
||||||
|
6、低功耗模式下使用excamera请参考lowpower DEMO，链接：https://docs.openluat.com/air780epm/luatos/app/lowpower/sleep/#_1

# AirCAMERA_1040 DEMO
|
||||||
|
|
||||||
|
## 演示功能概述
|
||||||
|
|
||||||
|
本示例主要是展示 AirCAMERA_1040 的使用，本地拍摄照片后通过 httpplus 扩展库将图片上传至 air32.com
|
||||||
|
|
||||||
|
1、main.lua：主程序入口
|
||||||
|
|
||||||
|
2、take_photo_http_post.lua：执行拍照后使用推送照片上传至air32.cn服务器，该服务器为虚拟服务器，仅用于演示，实际使用时请替换为自己的服务器。
|
||||||
|
|
||||||
|
3、scan_code.lua：扫描二维码应用DEMO模块
|
||||||
|
|
||||||
|
4、netdrv_4g.lua：联网状态检测模块
|
||||||
|
|
||||||
|
5、photo_to_aircloud.lua：执行拍照后使用推送照片上传至aircloud平台
|
||||||
|
|
||||||
|
注意事项：
|
||||||
|
|
||||||
|
- 拍照或者扫描模式需要在摄像头初始化时确定
|
||||||
|
- 如使用拍照模式就无法使用扫描模式，扫描模式同理
|
||||||
|
- 需要拍照后执行扫描的话需要重新初始化
|
||||||
|
- 所以拍照和扫描不可同时使用，如需切换模式需重新初始化
|
||||||
|
- 因为Air32.com平台已经不开放使用了，所以该DEMO仅作上传照片至服务器的演示作用，使用时请将上传URL修改为您自己的服务器地址，或者通过excloud扩展库上传到合宙IOT平台uploadtest.luatos.com
|
||||||
|
|
||||||
|

@author 陈取德

@usage
|
||||||
|
本demo主要使用AirCAMERA_1050 gc0310摄像头完成一次拍照上传任务
|
||||||
|
Air780EPM的sys ram内存资源只有2.3M，在使用camera功能时，需要非常谨慎，避免内存泄漏导致系统崩溃，需要注意以下情况：
|
||||||
|
1、exmcamera业务执行时，必须要确保有连续的内存空间，否则会导致excamera.open()初始化失败，需要的空间计算方式为：
|
||||||
|
（ 摄像头像素高 X 摄像头像素宽 X 2 ），用“GC032A”举例，内存空间为：640 * 480 * 2 = 614400 (B) ≈ 620KB
|
||||||
|
2、当使用ZBUFF方式存储照片，或者将照片放到 /ram/ 路径下保存时，必须确保有更多的内存连续空间，需要的总空间大小计算方式为：
|
||||||
|
（ 摄像头像素高 X 摄像头像素宽 X 3.5 ），用“GC032A”举例，内存空间为：640 * 480 * 3.5 = 1075200 (B) ≈ 1MB
|
||||||
|
3、本DEMO为常规模式下，摄像头稳定供电使用，DEMO逻辑为excamera.open()初始化完摄像头后，只需要重复调用excamera.photo()拍照即可，不需要反复的初始化关闭摄像头；
|
||||||
|
4、在实际应用中，务必将摄像头初始化的优先级排前，因为摄像头业务占用内存过大，尽早的初始化可以确保摄像头初始化时拿到足够的连续内存，确保后续拍照时能够正常执行；
|
||||||
|
5、Air780EPM的内存非常有限，在摄像头需求高的产品设计中，请选择Air780EHM/EGH/EHV、Air8000、Air700ECH这类 8MB + 8MB 的SOC，更大的内存才是摄像头业务稳定运行的最优解；
|
||||||
|
6、低功耗模式下使用excamera请参考lowpower DEMO，链接：https://docs.openluat.com/air780epm/luatos/app/lowpower/sleep/#_1

# AirCAMERA_1050 DEMO
|
||||||
|
|
||||||
|
## 演示功能概述
|
||||||
|
|
||||||
|
本示例主要是展示 AirCAMERA_1050 的使用，本地拍摄照片后通过 httpplus 扩展库将图片上传至 air32.com
|
||||||
|
|
||||||
|
1、main.lua：主程序入口
|
||||||
|
|
||||||
|
2、take_photo_http_post.lua：执行拍照后使用推送照片上传至air32.cn服务器，该服务器为虚拟服务器，仅用于演示，实际使用时请替换为自己的服务器。
|
||||||
|
|
||||||
|
3、scan_code.lua：扫描二维码应用DEMO模块
|
||||||
|
|
||||||
|
4、netdrv_4g.lua：联网状态检测模块
|
||||||
|
|
||||||
|
5、photo_to_aircloud.lua：执行拍照后使用推送照片上传至aircloud平台
|
||||||
|
|
||||||
|
注意事项：
|
||||||
|
|
||||||
|
- 拍照或者扫描模式需要在摄像头初始化时确定
|
||||||
|
- 如使用拍照模式就无法使用扫描模式，扫描模式同理
|
||||||
|
- 需要拍照后执行扫描的话需要重新初始化
|
||||||
|
- 所以拍照和扫描不可同时使用，如需切换模式需重新初始化
|
||||||
|
- 因为Air32.com平台已经不开放使用了，所以该DEMO仅作上传照片至服务器的演示作用，使用时请将上传URL修改为您自己的服务器地址，或者通过excloud扩展库上传到合宙IOT平台uploadtest.luatos.com
|
||||||
|
