* Move libboot_control to boot_control 1.1Tianjie Xu2020-02-261-102/+0
| | | | | | | | | | | It should belong to the default /misc implementation of boot control 1.1. Right now, it's only used by cuttlefish. So move it over to reduce confusion in bootloader_message. Bug: 131775112 Test: build Change-Id: If09bc6f4cc8adf74c8798048c8e54ec94566abaa (cherry picked from commit dc4d2a70db40a302cb7001ddbc41816e7187d5c5)
* bootloader_message: Add a magic header to the Virtual A/B message block.David Anderson2019-11-211-2/+4
| | | | | | | | | This adds a sanity check in addition to the version number in case misc contains random bits. Bug: 139156011 Test: manual test Change-Id: Ie4f3731d2b1795340881c88e0c4eec9cd4432653
* Consolidate the vendor space misc usage for PixelsTianjie Xu2019-11-121-8/+7
| | | | | | | | | | | | | | | | The layout of the vendor space /misc partition was pretty confusing and lead to some usage conflicts. To formalize the layout, we create a pixel specific library with the definition & offset of various flags. The new library also handles the R/W. As a result, we will leave system domain /misc definitions in the libbootloader_message. We also switch the misc_writer binary to use more specific options instead of writing an arbitrary hex string. So we can avoid redefining the string & offset in both init script and recovery ui. Bug: 131775112 Test: unit tests pass, run misc_writer and check contents of /misc Change-Id: I00f8842a81d1929e31a1de4d5eb09575ffad47c0
* bootloader_message: Add helpers for handling IBootControl MergeStatus.David Anderson2019-11-091-0/+26
| | | | | | | | | | | | | | | | Move merge_status from bootloader_control_ab, which is in vendor space, to a new generic AOSP struct in system space. This will allow more devices to share the same HAL implementation. This patch also changes libboot_control to compensate for merge_status moving out of vendor space. The reference HAL library now also provides separate helper functions for managing the merge status, so devices using a custom boot control HAL can still take advantage of the new misc implementation. Bug: 139156011 Test: manual test Change-Id: I5cd824e25f9d07aad1476301def5cdc3f506b029
* bootloader_message: Carve out space reserved for system.David Anderson2019-11-051-1/+4
| | | | | | | | | | This reduces the wipe space from 32K to 16K. The wipe space is now at the 16K-32K region. The 32K-64K region is now "system space", to complement the vendor space, for generic AOSP usage. Bug: 139156011 Test: manual test Change-Id: I1474bfa65a5f21049ab64ec0aee2f4585b55f60f

* Add misc_writer.Tao Bao2019-05-211-2/+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`).

* Add update_channel field to bootloader_message_ab.Sen Jiang2018-01-231-1/+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
* Switch to bionic gtest in bootable/recoveryTianjie Xu2017-11-031-0/+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
* Boot control HAL based on the A/B headers.Alex Deymo2017-04-031-0/+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.

* Add update_bootloader_message() to fix two-step OTAs.Tao Bao2016-12-151-1/+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
