- Strictly adhere to the System V AMD64 ABI by skipping the 128-byte "Red Zone" before modifying the stack, see page 23 of https://gitlab.com/x86-psABIs/x86-64-ABI/-/jobs/artifacts/master/raw/x86-64-ABI/abi.pdf?job=build for details.
- Added `inject_via_staging` as a fallback strategy:
1. Copies the payload to `/data/local/tmp`.
2. Sets permissions/context (`u:object_r:system_file:s0`).
3. Loads via standard `dlopen`.
4. Immediately unlinks the file for stealth.
- Introduced `RegisterRestorer` RAII class to guarantee original registers are restored even if the injection logic returns early due to error.
The following two bugs are fixed:
1. `zygisk.json` is renamed to `update.json`, which is indicated in `module.prop`.
2. To avoid over optimization of R8, we must keep certains packages, which are found after many experiments.
This commit introduces the main application subproject, 'app', and sets up the necessary infrastructure for the TEESimulator.
Key changes:
* 'app' Subproject Setup: Added the new :app module with its initial structure, including build files, manifest, and Kotlin main entry point.
* LSPlt Integration: Added the LSPlt hooking framework as a Git submodule in app/src/main/cpp/external/ and configured its use in CMake.
* Native Build Configuration: Configured the C++ build to use LSPlt statically and compile two essential native libraries: libinject.so (for injection) and libTEESimulator.so (for interception/logic).
* Module Packaging: Implemented complex Gradle logic within app/build.gradle.kts to automate the creation of a flashable zip module (supporting Magisk, Ksu, and Apatch) with versioning based on Git information.
* Initial Module Files: Added the template files (module.prop, update-binary, updater-script) for the flashable module structure.
