From 170ad599540dfeee252ebf53cbedd610c2d22a5f Mon Sep 17 00:00:00 2001 From: Kelvin Zhang Date: Tue, 14 Mar 2023 15:02:53 -0700 Subject: Allow brick OTA package to be sideloaded in recovery Makes testing easier, brick packaegs can now be tested directly in recovery w/o having to go through GOTA. Test: adb sideload brick_ota.zip Bug: 273561331 Change-Id: I48214dc03e63b69e61fc217bc3f58923bb90a9a6 --- install/include/install/wipe_device.h | 1 + install/install.cpp | 18 +++++++++++++++++- install/wipe_device.cpp | 8 ++++++-- 3 files changed, 24 insertions(+), 3 deletions(-) diff --git a/install/include/install/wipe_device.h b/install/include/install/wipe_device.h index 903ddfdcd..19e7c65bf 100644 --- a/install/include/install/wipe_device.h +++ b/install/include/install/wipe_device.h @@ -24,6 +24,7 @@ // Wipes the current A/B device, with a secure wipe of all the partitions in RECOVERY_WIPE. bool WipeAbDevice(Device* device, size_t wipe_package_size); +bool WipeAbDevice(Device* device, Package* wipe_package); // Reads the "recovery.wipe" entry in the zip archive returns a list of partitions to wipe. std::vector GetWipePartitionList(Package* wipe_package); diff --git a/install/install.cpp b/install/install.cpp index 30ba94c26..a9786cfdf 100644 --- a/install/install.cpp +++ b/install/install.cpp @@ -48,6 +48,7 @@ #include "install/spl_check.h" #include "install/wipe_data.h" +#include "install/wipe_device.h" #include "otautil/error_code.h" #include "otautil/package.h" #include "otautil/paths.h" @@ -71,6 +72,8 @@ static constexpr float VERIFICATION_PROGRESS_FRACTION = 0.25; // The charater used to separate dynamic fingerprints. e.x. sargo|aosp-sargo static const char* FINGERPRING_SEPARATOR = "|"; static constexpr auto&& RELEASE_KEYS_TAG = "release-keys"; +// If brick packages are smaller than |MEMORY_PACKAGE_LIMIT|, read the entire package into memory +static constexpr size_t MEMORY_PACKAGE_LIMIT = 1024 * 1024; static std::condition_variable finish_log_temperature; static bool isInStringList(const std::string& target_token, const std::string& str_list, @@ -382,7 +385,20 @@ static InstallResult TryUpdateBinary(Package* package, bool* wipe_cache, return INSTALL_CORRUPT; } - bool package_is_ab = get_value(metadata, "ota-type") == OtaTypeToString(OtaType::AB); + const bool package_is_ab = get_value(metadata, "ota-type") == OtaTypeToString(OtaType::AB); + const bool package_is_brick = get_value(metadata, "ota-type") == OtaTypeToString(OtaType::BRICK); + if (package_is_brick) { + LOG(INFO) << "Installing a brick package"; + if (package->GetType() == PackageType::kFile && + package->GetPackageSize() < MEMORY_PACKAGE_LIMIT) { + std::vector content(package->GetPackageSize()); + if (package->ReadFullyAtOffset(content.data(), content.size(), 0)) { + auto memory_package = Package::CreateMemoryPackage(std::move(content), {}); + return WipeAbDevice(device, memory_package.get()) ?
