* bootloader_message: Add a magic header to the Virtual A/B message block.David Anderson2019-11-211-1/+3
| | | | | | | | | 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
* bootloader_message: Add helpers for handling IBootControl MergeStatus.David Anderson2019-11-092-9/+94
| | | | | | | | | | | | | | | | 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.

* bootable: leak less memoryGeorge Burgess IV2019-10-231-1/+2
| | | | | | | | | | | `misc_device_` is a std::string, so it allocates and manages its own memory. Hence, the strdup here is immediately leaked. Caught by the static analyzer Bug: None Test: TreeHugger Change-Id: Iffb1ff60f6087e470a0979d202150567272e8b1c
* Add IBootControl 1.1 support to libboot_control.David Anderson2019-09-053-0/+30

* Improve error messaging when bootcontrol HAL fails to load.David Anderson2019-09-051-2/+8

* boot_control: Don't allow current_slot_ to be -1.David Anderson2019-09-051-0/+4
| | | | | | | | | | | If the HAL is run on a non-A/B device, it does not fail gracefully; it will segfault because the current_slot is -1 and methods do not protect against this. Instead, have Init() fail if we can't determine the current slot. Bug: 130078382 Test: vts tests Change-Id: I2d3094518a842b1a764427d2da9d46781a9f26da
* Make libboot_control vendor available.David Anderson2019-08-301-1/+2

* Refactor boot_control into a separate library.David Anderson2019-08-304-134/+256
| | | | | | | | | | | This extracts the implementation of boot_control into a new library, libboot_control. The bootctrl.default module now wraps this library. This refactoring will allow us to re-use the same implementation in HIDL. Bug: 138861550 Test: mm bootctrl.default Change-Id: Ic0558da3c2d8e6f5ebec63a497825c24b51623b7

* Drop -Wno-unused-parameter.Tao Bao2017-10-121-2/+1
| | | | | | | The only one left is libedify. Will handle that in a separate CL. Test: mmma bootable/recovery Change-Id: I732a5f85229da90fd767bee2e46c5c95f529c396
* Boot control HAL based on the A/B headers.Alex Deymo2017-04-032-0/+435
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.
