okhsunrog 35b3dcdf50 build: align native cdylib on 16 KiB; unify kmod/zygisk build scripts
Two related changes that ship together because they touch the same
build-script + docs surface and were verified together on-device.

16 KiB alignment
  - zygisk/build.rs: pass `-Wl,-z,max-page-size=16384` to lld so the
    cdylib's LOAD segments line up on 16 KiB pages. NDK r28+ already
    does this by default, but the flag keeps r27 builds compatible.
  - lsposed/native/build.rs: new file, same flag, for libvpnhide_checks.so.
  - docs/development.md: bumped the NDK requirement to r28+ and noted
    the 16 KiB rationale.

Verified via `llvm-readelf -l`: both libvpnhide_zygisk.so and
libvpnhide_checks.so now show `Align 0x4000` on every LOAD segment.

Unified build entry points
  - kmod/build.py replaces kmod/build-zip.py. Single script that
    auto-detects whether to build natively (we're inside the DDK image
    or `--kdir` was passed) or to spawn `ghcr.io/ylarod/ddk-min` via
    podman/docker. CI uses the same script with `--inside-container`.
  - zygisk/build-zip.py renamed to zygisk/build.py for symmetry; logic
    unchanged.
  - kmod/BUILDING.md rewritten — local build is now one command:
    `./kmod/build.py --kmi android14-6.1` (or `--all`). The old
    hand-rolled podman/docker recipes are gone.
  - .github/workflows/ci.yml updated to call the new entry points.
    The DDK image tag in CI now has a comment pointing at
    `DDK_IMAGE_TAG` in kmod/build.py as the source of truth.
  - README.{md,en.md}, kmod/README.md, zygisk/README.md, docs/releasing.md,
    scripts/build_lib.py: reference updates.
  - README.en.md: also fixes a "bacame" typo and tightens the Windows
    zygisk-build note (the aux.rs / libgit2 issue is still real).

Verified end-to-end on Pixel 8 Pro (husky, android14-6.1, Android 16):
APK installs, kmod + zygisk modules load, all 26 self-checks PASS in
Enforcing, 22/26 PASS in Permissive (the same 4 by-design FAILs as
before — kmod doesn't cover those paths in Permissive).

Releasing

Model

  • VERSION file = the last released version on main. It is only modified by release.py.
  • changelog.d/*.md = work in progress. One Markdown file per unreleased entry, accumulated via ./scripts/changelog.py during normal development. See changelog.md.
  • Intermediate builds (main, feature branches, local) get a version string derived from git describe — propagated into module.prop / APK versionName at build time. See build versions below.

Cutting a release

  1. Make sure everything you want in the release is merged to main and changelog.d/ contains exactly the fragments that should appear in the release notes.
  2. Run the release script with the new version:
    ./scripts/release.py 0.6.2
    
    Atomically:
    • rotates every fragment under changelog.d/ into history[0] with version: "0.6.2" and deletes the fragment files,
    • writes 0.6.2 to VERSION,
    • patches versionName/versionCode in every module.prop, Cargo.toml, and build.gradle.kts,
    • regenerates CHANGELOG.md and update-json/changelog.md.
  3. Commit, tag, push:
    git commit -am "chore: release v0.6.2"
    git tag v0.6.2
    git push
    git push origin v0.6.2
    
  4. Wait for CI to finish the build. CI creates a draft GitHub release with all artifacts attached and release notes extracted from CHANGELOG.md — review it on the Releases page and click Publish release when you're happy.
  5. Generate update-json files pointing at the new release assets:
    ./scripts/update-json.sh
    
  6. Commit and push:
    git commit -am "chore: update-json for v0.6.2"
    git push
    

Why update-json is a separate commit

Update-json must be committed after the GitHub release is published (i.e. after you promote the draft to public). Magisk and KSU fetch these files to decide whether an update is available, then download the zip from the URL inside. Draft releases are private — their asset URLs require auth — so update-json must not point at them.

Notes

  • versionCode is derived automatically by release.py as major*10000 + minor*100 + patch (e.g. 0.6.2602).
  • If changelog.d/ is empty when you run release.py, it warns but proceeds — useful for version-only bumps.
  • release.py refuses to release a version that already exists in history[].

Build versions

Every packaging step runs ./scripts/build-version.py to compute the version string stamped into the artifact:

  • On a release tag vX.Y.Z: X.Y.Z
  • N commits after the nearest tag: X.Y.Z-N-gSHA (the git describe format)
  • Working tree dirty: additional -dirty suffix
  • No git / no tags: falls back to the VERSION file

This string goes into:

  • module.prop version=... (visible in the Magisk/KSU manager app)
  • APK versionName (visible in Android Settings → Apps, diagnostic debug zip, BuildConfig.VERSION_NAME)
  • Inside the zip filenames (only for release tags; dev artifacts in CI keep a stable name)

The committed module.prop files are not modified — kmod/build.py and zygisk/build.py stage a copy, patch the version there, and zip. lsposed/app/build.gradle.kts evaluates build-version.py at configure time and sets versionName dynamically.

versionCode stays at the value baked in by the last release.py run (monotonically increasing integer required by Android/Magisk).
