okhsunrog 9ba7bfb127 refactor: drop WebUI and action.sh from kmod and zygisk modules

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.

Building vpnhide-kmod

Most users should download pre-built modules from Releases — builds are provided for all supported GKI generations. This guide is for contributors or users who need to build from source.

Quick build with DDK (recommended)

The easiest way to build is using the same DDK Docker images that CI uses. No kernel source clone, no toolchain setup.

# Pick your GKI generation (see "Identifying your GKI generation" below)
KMI=android14-6.1

# Build the kernel module
docker run --rm -v $(pwd)/kmod:/work \
    ghcr.io/ylarod/ddk-min:${KMI}-20260313 sh -c "
    CLANG=\$(echo /opt/ddk/clang/clang-r*/bin) && \
    make -C /opt/ddk/kdir/${KMI} M=/work \
        ARCH=arm64 LLVM=1 LLVM_IAS=1 \
        CC=\$CLANG/clang LD=\$CLANG/ld.lld \
        AR=\$CLANG/llvm-ar NM=\$CLANG/llvm-nm \
        OBJCOPY=\$CLANG/llvm-objcopy \
        OBJDUMP=\$CLANG/llvm-objdump \
        STRIP=\$CLANG/llvm-strip \
        CROSS_COMPILE=aarch64-linux-gnu- \
        modules"

# Package as KSU module
cp kmod/vpnhide_kmod.ko kmod/module/
(cd kmod/module && zip -qr ../../vpnhide-kmod.zip .)

Local build with kernel source

If you prefer building against a local kernel source tree (e.g. for development or debugging), use the Makefile with direnv:

cd kmod/
cp .env.example .env
# Edit .env with paths to your kernel source and clang toolchain
direnv allow
make
./build-zip.sh

See .env.example for the required variables. You need a prepared kernel source tree with headers and Module.symvers.

Identifying your GKI generation

adb shell uname -r

The output looks like 6.1.75-android14-11-g... — the generation is android14-6.1.

Note: the android14 part is NOT your Android version — it's the kernel generation. All Pixels from 6 to 9a share the same android14-6.1 kernel. Pixel 10 series moves to android16-6.12.

`uname -r` pattern	GKI generation
`5.10.xxx-android12-...`	android12-5.10
`5.10.xxx-android13-...`	android13-5.10
`5.15.xxx-android13-...`	android13-5.15
`5.15.xxx-android14-...`	android14-5.15
`6.1.xxx-android14-...`	android14-6.1
`6.6.xxx-android15-...`	android15-6.6
`6.12.xxx-android16-...`	android16-6.12

Install and test

adb push vpnhide-kmod.zip /sdcard/Download/
# Install via KernelSU-Next manager -> Modules -> Install from storage
# Reboot

Verify after reboot:

adb shell "su -c 'lsmod | grep vpnhide'"
adb shell "su -c 'dmesg | grep vpnhide'"
adb shell "su -c 'cat /proc/vpnhide_targets'"

Troubleshooting

insmod: Exec format error — symvers CRC mismatch. Use the DDK build (matched symvers).

insmod: File exists — module already loaded. rmmod vpnhide_kmod first.

kretprobe not firing — check dmesg | grep vpnhide for registration messages and /proc/vpnhide_targets for correct UIDs. Target app UIDs change on reinstall — re-resolve via the VPN Hide app.
