2019-05-21Add misc_writer.Tao Bao1-2/+11
bootloader_message.h currently divides /misc into four segments. The space between 2K and 16K is reserved for vendor use (e.g. bootloader persists flags). This CL adds a vendor tool "misc_writer", to allow writing data to the vendor space in /misc, before getting a dedicated HAL for accessing /misc partition (b/131775112). Targets need to explicitly include the module, then invoke the executable to write data. For example, the following command will write 3-byte data ("0xABCDEF") to offset 4 in vendor space (i.e. 2048 + 4 in /misc). $ /vendor/bin/misc_writer --vendor-space-offset 4 --hex-string 0xABCDEF Bug: 132906936 Test: Run recovery_unit_test on crosshatch. Test: Call the command via init.hardware.rc on crosshatch. Check that the call finishes successfully. Then check the contents written to /misc (`dd bs=1 skip=2048 if=/dev/block/sda2 count=32 | xxd`).

2018-01-23Add update_channel field to bootloader_message_ab.Sen Jiang1-1/+5
The update_channel field is used to store the Omaha update channel if update_engine is compiled with Omaha support. We need it to be in misc to persist through factory reset. Bug: 72332119 Test: mma Change-Id: Ied4fecc6e78cc69d33a36ba4d101d675100f9d82
2017-11-03Switch to bionic gtest in bootable/recoveryTianjie Xu1-0/+5
We encountered segfaults in Imgdiff host tests due to the failure to reset states of getopt. The problem can be solved by switching to use bionic's gtest where a new process is forked for each test. Also modify the recovery_component_test to make sure it runs in parallel. Changes include: 1. Merge the writes to misc partition into one single test. 2. Change the hard coded location "/cache/saved.file" into a configurable variable. Bug: 67849209 Test: recovery tests pass Change-Id: I165d313f32b83393fb7922c5078636ac40b50bc2
2017-04-03Boot control HAL based on the A/B headers.Alex Deymo1-0/+5
The added bootctrl.bcb module implement the legacy interface for the bootctrl HAL based on the Boot Control Block (BCB) and the headers already specified in the booloader_message library. This serves as a reference implementation of the boot_control HAL. Bug: 32707546 Test: Tested internally that a device can use this HAL to flip slots and recovery from a /misc wipe.

2016-12-15Add update_bootloader_message() to fix two-step OTAs.Tao Bao1-1/+6
This is a retry of commit 7e31f421a514da09b90e46dbd642a5e9b16e0003. Commit bd56f1590c967205dc45eb2ec298aa8d2aacb740 switches to calling write_bootloader_message(<options>) in get_args(), which unintentionally resets the stage field thus breaks two-step OTAs. This CL adds update_bootloader_message(<options>), which only sets the command field (to "boot-recovery") and the recovery field (with the specified options). Bug: 33534933 Test: Apply a two-step package. Test: recovery_component_test passes. Change-Id: Ie0b1ed4053d2d3c97d9cb84310d616b28fcfc72e

2016-11-18updater: Refactor set_stage() and get_stage() functions.Tao Bao1-0/+18
Add read_bootloader_message_from() and write_bootloader_message_to() to allow specifying the BCB device (/misc). Also add testcases for set_stage() and get_stage(). Test: recovery_component_test passes. Test: Build a recovery image and apply a two-step OTA package. Change-Id: If5ab06a1aaaea168d2a9e5dd63c07c0a3190e4ae

bootloader_messages merges bootloader_message_writer and bootloader.cpp, so we can use the same library to manage bootloader_message in normal boot and recovery mode.
