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).
Six unrelated drift fixes that accumulated since they were last
synced. Each is independent of the rest:
* README{.en,}.md — kmod claim "filters /proc/net/*" trimmed to
/proc/net/route. The other /proc/net files are SELinux-blocked
for untrusted apps and the coverage table already says so.
* kmod/README.md — hook table and architecture note updated from
dev_ifconf to sock_ioctl. dev_ifconf gets inlined by Clang LTO
on GKI 5.10 so the kretprobe silently never fires; sock_ioctl
has been the actual hook target since the vpnhide_kmod.c fix.
* zygisk/README.md — five inline hooks now, not four (recv was
added separately because bionic's recv tail-calls recvfrom).
Also clarified pre_app_specialize runs in the forked child, not
zygote, matching the lifecycle block in lib.rs.
* docs/development.md — JDK requirement matches CI image (17, not
21); document ANDROID_NDK_ROOT quirk for Gobley; CI lint list
expanded to match what ci.yml actually runs.
* docs/development.md + lsposed/README.md — explain Gobley (the
Gradle plugin pair that builds lsposed/native/ and bundles the
.so + UniFFI Kotlin bindings into the APK). Previously absent
from all *.md.
The VPN Hide app is now the sole UI for target management. WebUI was
KernelSU-Next-only and redundant since the app works on both KSU and
Magisk. Remove webroot/, action.sh, and all references across docs,
install scripts, module descriptions, and code comments.
The lsposed APK now includes a Compose target picker UI that works
with both kmod and zygisk on any root solution. Update all READMEs
to recommend the app over WebUI (which is KernelSU-only).
Root README is now the single source for shared content (verified
against, split tunneling, threat model, component overview). Sub-READMEs
focus on component-specific technical details and link back to root.
- Remove ~700 lines of duplicated content across sub-READMEs
- Update all cross-references to use monorepo relative paths
- Add test-app to components table
- Update zygisk README: mark openat/recvmsg/SIOCGIFCONF as implemented
- Fix stale links to archived repos
- Remove specific commercial app/bank names from all READMEs, comments,
and log messages to avoid legal issues. Open-source detection tools
(RKNHardering, YourVPNDead) are kept with links.
- Rewrite test-app in Jetpack Compose with Material3 dynamic colors,
edge-to-edge, system dark/light theme support.
- Make test UI more verbose with detailed result cards.
- Add full logcat output for all checks (tag: VPNHideTest) for
automated testing by AI agents.
- Fix 16KB page alignment for Android 15+.
Unified repository for the complete Android VPN-hiding stack:
- zygisk/ — Rust Zygisk module (inline libc hooks via shadowhook)
- lsposed/ — Kotlin LSPosed module (Java API + system_server hooks)
- kmod/ — C kernel module (kretprobe hooks, invisible to anti-tamper)
CI workflows use path filters to build only the changed component.
