* Check SPL downgrade before install OTA in recoveryKelvin Zhang2021-05-171-0/+7
| | | | | | | | | | | | | | | | | | Applying an SPL downgrade package can cause boot failures (/data failed to decrypt). Today's ota_from_target_files tool already try to prevent this. But Packages generated using older tools are still around. Add check in recovery to prevent such OTA package from installing. Test: th Test: Sideload an OTA with newer SPL, make sure check passes Test; Sideload an OTA with older SPL, make sure check fails Bug: 186581246 Change-Id: Icffe8097521c511e151af023a443ccbb4b59e22c
* Check for overflow before allocating memory fore decompression.Kelvin Zhang2020-09-181-1/+7
| | | | | | | | On 32bit devices, an ZipEntry64 may have size > 2^32, we should check for such cases before attempting to allocate memory. Test: mm -j Change-Id: I0f916ef4b2a692f167719a74bd6ff2e887c6c2ce
* Switch to zip64 in recoveryKelvin Zhang2020-09-161-4/+4
| | | | | | | | | There's already library support for zip64 in libziparchive. We just need to start using the new APIs. Bug: 167951876 Test: Sideload a large ota package in recovery Change-Id: I652741965f28de079d873c6822317ee9fa855201
* Add recovery support of dynamic fingerprintsKelvin Zhang2020-06-291-3/+23
| | | | | | | | | | | | After http://go/aog/1306461, the metadata in the OTA package can have multiple fingerprints or device names e.g. from pre-device=lmiin to pre-device=lmiin|lmiinpro This CL updates recovery code to recognize them Test: Added unit tests for this Bug: 159850736 Change-Id: If6315bf2d3dea77abb9d7d83145f55b0148cdfb1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check the package metadata to determine whether this is an A/B or non-A/B update package. This is more accurate. Also checks ro.virtual_ab.allow_non_ab flag. This is useful for continuously supporting (and testing) non-A/B.

* | Force off-device package installation with FUSETianjie Xu2020-02-131-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The non-A/B package installation is subject to TOC/TOU flaw if the attacker can switch the package in the middle of installation. And the most pratical case is to store the package on an external device, e.g. a sdcard, and swap the device in the middle. To prevent that, we can adopt the same protection as used in sideloading a package with FUSE. Specifically, when we install the package with FUSE, we read the entire package to cryptographically verify its signature. The hash for each transfer block is recorded in the memory (TOC), and the subsequent reads (TOU) will be rejected upon dectecting a mismatch. This CL forces the package installation with FUSE when the package stays on a removable media. Bug: 136498130 Test: Run bin/recovery --update_package with various paths; and packages are installed from FUSE as expected Test: recovery_unit_test - no new failures Change-Id: Ia5afd19854c3737110339fd59491b96708926ae5 Merged-In: I35119c2334895aa0ef4ed71b3ddd08f280c0c031

* otautil: Factor out the utils that're private to recovery.Tao Bao2019-10-021-2/+2
| | | | | | | | | | | A number of utility functions are intended for serving recovery's own use. Exposing them via libotautil (which is a static lib) would pass the dependencies onto libotautil's users (e.g. recovery image, updater, host simulator, device-specific recovery UI/updater extensions etc). This CL finds a new home for the utils that are private to recovery. Test: mmma bootable/recovery Change-Id: I575e97ad099b85fe1c1c8c7c9458a5a43d4e11e1
* Clean up some global variables in common.hTianjie Xu2019-07-241-1/+4
| | | | | | | | | | | | | | Some global variables are only used for recovery.cpp and recovery_main.cpp, remove them from common.h and handle their usage accordingly. Variables include: static constexpr int kRecoveryApiVersion; extern struct selabel_handle* sehandle; extern RecoveryUI* ui; extern bool has_cache; bool is_ro_debuggable(); Test: unit tests pass, boot into recovery mode and run graphic tests Change-Id: If83a005786c9b38412731da97aaf85af69a3b917

* install: Return bool for a few check functions.Tao Bao2019-04-301-33/+31
| | | | | | | | | | | | | | | The results from these functions have boolean semantics. They're returning `int` prior to this CL, with some of them mixing 0 and InstallResult. Note that SetUpNonAbUpdateCommands() was returning INSTALL_CORRUPT / INSTALL_ERROR / 0 prior to this change, but all the callers handle INSTALL_CORRUPT and INSTALL_ERROR the same way. This CL changes them to return bool instead. Test: `mmma -j bootable/recovery` Test: TreeHugger Test: Sideload on taimen. Change-Id: Ic1b5dbf79aaca68b53ab8ea2c8ba3d19f988c571
* Move wipe cache|data to libinstallxunchang2019-04-151-5/+13
| | | | | | | | | | | | | | | Therefore, libinstall becomes the sole owner to handle the request from minadbd service. The change also includes 1. move logging.cpp out of librecovery 2. drop the dependency on common.h 3. now it's more sensible to move the wipe_cache as part of install_package. move the wipe_cache to the end of the function.
