Distribute kernel via Gitea Debian apt repo; track stable not mainline
- Publish .deb packages to Gitea's built-in Debian registry (apt source) instead of Releases; CI uploads to pool/stable/main and stops creating Releases. One apt source line serves amd64 and arm64. - Add linux-image-bbrv3 meta-package so `apt upgrade` tracks the latest stable kernel while older kernels stay installed for fallback. Its dependency is the actual built image package name (immune to localversion drift). - Add bbrv3-config package shipping the BBR+CAKE+ECN sysctl drop-in as a conffile (applied via postinst), replacing the installer's sysctl write. - Rewrite install.sh to add the apt source + signing key and install the meta package; keep the OS-version gate, status check and uninstall menu, plus an apt-mark hold escape hatch. - select-stable-kernel.sh: pick the highest stable point release whose series is below mainline and has a matching BBRv3 patch, so a freshly-cut series (latest stable == mainline, e.g. 7.1) is not built. Currently 7.0.12. - Exclude linux-libc-dev (clashes with the distro's headers) and drop the "by Joey" MODULE_DESCRIPTION step and release branding.

BBR 实现不会在自动构建时偷偷更新；自动更新的是 Linux stable 内核的小版本。

|

当前 patch 选择规则：
|
**追踪的是成熟 stable，而非 mainline。** 一个新系列（如 `7.1`）刚发布时，kernel.org 的 “latest stable” 会瞬间等于 “latest mainline”——那其实还是尖端，不是经过 `.z` 打磨的 stable。因此构建脚本（`scripts/select-stable-kernel.sh`）只在满足以下**全部**条件的版本里取最高：
|
||||||
|
|
||||||
|
- 是带三段点号的点版本 `X.Y.Z`（排除刚发布、仅显示为 `X.Y` 的新系列）；
|
||||||
|
- 系列 `X.Y` 严格低于当前 mainline（排除仍等于 mainline 的系列）；
|
||||||
|
- 仓库存在对应的 `patches/bbrv3-linux-X.Y.patch`。
|
||||||
|
|
||||||
|
当前 patch：
|
||||||
|
|
||||||
```text
|
```text
|
||||||
linux-7.0.y -> patches/bbrv3-linux-7.0.patch
|
patches/bbrv3-linux-7.0.patch # linux-7.0.y
|
||||||
linux-7.1.y -> patches/bbrv3-linux-7.1.patch
|
patches/bbrv3-linux-7.1.patch # linux-7.1.y
|
||||||
```
|
```
|
||||||
|
|
||||||
同一主线系列内的小版本更新会自动复用同一个 patch，例如 `7.0.11 -> 7.0.12`。如果内核跳到新的主线系列但仓库内还没有对应 patch，构建会直接失败，避免产出不可验证的内核包。
|
同系列小版本更新自动复用同一 patch（如 `7.0.11 -> 7.0.12`）。等新系列出了点版本、且 mainline 前移到再下一个系列，构建会自动接棒到新系列（前提是其 patch 已就位）。

# BBRv3 内核分发改造：迁移到 Gitea Debian apt 源
|
||||||
|
|
||||||
|
日期：2026-06-17
|
||||||
|
状态：已确认，进入实现
|
||||||
|
|
||||||
|
## 背景与目标
|
||||||
|
|
||||||
|
当前分发链路是「Gitea Releases 存 `.deb` + `curl|bash` 安装脚本手动 `dpkg -i`」。
|
||||||
|
目标是改成 **apt 源**，让用户 `apt upgrade` 即可时刻跟随最新 stable 内核，并顺带提升
|
||||||
|
安全性（GPG 签名、保留旧内核可回退、apt 解依赖）。
|
||||||
|
|
||||||
|
构建层（CI 每天编译 `.deb`）保留不变；本次只替换**分发/更新层**。
|
||||||
|
|
||||||
|
## 关键决策
|
||||||
|
|
||||||
|
1. **分发层 = Gitea 自带 Debian package registry**（实例已自建 Gitea，自动 PGP 签名）。
|
||||||
|
- 上传：`PUT {server}/api/packages/{owner}/debian/pool/{dist}/{comp}/upload`
|
||||||
|
- 用户源：`deb [signed-by=…] {server}/api/packages/{owner}/debian stable main`
|
||||||
|
- 公钥：`{server}/api/packages/{owner}/debian/repository.key`
|
||||||
|
- 统一用 `stable/main` 一个桶；架构由 `.deb` 自带，apt 按 `amd64/arm64` 自动取。
|
||||||
|
2. **更新策略 = 自动跟最新**：构建 meta-package `linux-image-bbrv3`，`Depends` 当前最新
|
||||||
|
`linux-image-<ver>-bbrv3`，版本随内核版本走。`apt upgrade` 跟最新，**旧内核保留可回退**。
|
||||||
|
谨慎用户 `apt-mark hold linux-image-bbrv3` 钉死。
|
||||||
|
3. **sysctl 配置入包**：新增 `bbrv3-config`（`Architecture: all`），把
|
||||||
|
`/etc/sysctl.d/99-bbrv3.conf`（BBR + CAKE + ECN）作为 conffile 随包安装，`postinst`
|
||||||
|
跑 `sysctl --system`。装包即配置，不再依赖脚本。`meta` 依赖它。
|
||||||
|
4. **迁移 = 干净切换 + 保留入口**：CI 只发 registry，停发 Releases；`install.sh` 仍是同一
|
||||||
|
`curl|bash` 入口，菜单不变，动作改成 apt（加源 + 导 key + 装 meta）。
|
||||||
|
5. **只发 `linux-image` / `linux-headers`，排除 `linux-libc-dev`**（避免覆盖发行版 userspace
|
||||||
|
头文件）与 `*-dbg*`。
|
||||||
|
|
||||||
|
## 本次新增需求（用户补充）
|
||||||
|
|
||||||
|
6. **追踪 stable 而非 mainline**。根因：7.1.0 刚发布时 kernel.org「latest stable」== mainline
|
||||||
|
== 7.1，旧 preflight 直接取它就抓到 7.1；成熟 stable 实为 7.0.12。
|
||||||
|
**修法**：`scripts/select-stable-kernel.sh` 从 `finger_banner` 选「带三段点号 `X.Y.Z`、
|
||||||
|
`X.Y` 严格 `<` mainline、且仓库存在 `patches/bbrv3-linux-X.Y.patch`」中的最高版本。
|
||||||
|
三段号排除刚发布的 `7.1`，patch 闸门排除无补丁的 6.x → 当前命中 `7.0.12`。系列自动接棒。
|
||||||
|
7. **删除 joey 标签**：移除 `build.yml` 的「编译声明」步骤（注入 `Compiled & Optimized by
|
||||||
|
Joey` 的 `MODULE_DESCRIPTION`），让上游 patch 自带描述生效；Release 发布块里的 joey 文案
|
||||||
|
随该块一并删除。
|
||||||
|
|
||||||
|
## 改动清单
|
||||||
|
|
||||||
|
- `scripts/select-stable-kernel.sh`（新）— 选 stable 目标版本。
|
||||||
|
- `scripts/build-config-package.sh`（新）— 构建 `bbrv3-config_*_all.deb`。
|
||||||
|
- `scripts/build-meta-package.sh`（新）— 构建 `linux-image-bbrv3_<ver>_<arch>.deb`，依赖项
|
||||||
|
取自实际产出的内核包名（`dpkg-deb -f`），避免 localversion 后缀漂移。
|
||||||
|
- `.github/workflows/build.yml`（改）— preflight 用选择脚本 + 查 registry index 判存在；删
|
||||||
|
joey 步骤；构建 meta/config；发布改 registry `--upload-file`；停发 Release。
|
||||||
|
- `install.sh`（改）— 菜单动作改 apt：加源/导 key/装 meta（1）、装指定版本（2）、状态检查
|
||||||
|
（3，不变）、卸载并删源（4）。保留 OS 版本闸门、依赖安装、sudo 兜底。
|
||||||
|
- `README.md`（改）— 改写「内核来源/BBR 策略/菜单」，新增 apt 用法与 `apt-mark hold`。
|
||||||
|
|
||||||
|
## 前提（落地前核对）
|
||||||
|
|
||||||
|
- `git.chilldove.com` 启用 Packages → Debian registry（新版 Gitea 默认开）。
|
||||||
|
- CI 需 `PKG_TOKEN` secret（有 `write:package` scope）；自动注入的 `GITHUB_TOKEN` 不保证有
|
||||||
|
包写权限。
|
||||||
|
- registry 保留历史版本以支撑「装指定版本」；将来再议 retention。
|
||||||
|
|
||||||
|
## 不做（YAGNI）
|
||||||
|
|
||||||
|
- 不搭 aptly/reprepro、不自管 GPG key（Gitea 全包）。
|
||||||
|
- 不做过渡期双发布。
|
||||||
|
- 不按发行版分多 distribution。
