2021-12-09[MTE] Add interface to communicate MTE status to bootloader.Florian Mayer1-0/+10
We can use this interface to instruct the bootloader to either permanently or only for the next reboot enable MTE for userspace or kernel. Bug: 206895651 Change-Id: I7330e43b7c4f94fc5913a7bc0f667b6eab06e111
2019-11-12Consolidate the vendor space misc usage for PixelsTianjie Xu1-34/+3
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
2019-11-09bootloader_message: Add helpers for handling IBootControl MergeStatus.David Anderson1-0/+43
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
2019-11-05bootloader_message: Carve out space reserved for system.David Anderson1-0/+7
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
2019-08-07bootloader_message: Remove global std::stringVic Yang1-3/+4
A global std::string, even if not used, pollutes the bss section unnecessarily. Since this object is only there for testing, make it std::optional<std::string>, which is constexpr constructible. Bug: 138856262 Test: Along with a fix in fs_mgr, see that the bss section for libbootloader_message.so is now clean on cuttlefish for several processes.

2019-05-21Add misc_writer.Tao Bao1-0/+42
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`).

2019-01-31Add android::fs_mgr namespace for new Fstab codeTom Cherry1-0/+3
Also add libfstab dependencies where needed. Previously the `typedef struct FstabEntry Volume;` line served to both define a `struct FstabEntry` as well as alias Volume to it. With the new namespace for android::fs_mgr::FstabEntry, `struct FstabEntry` isn't compatible anymore, so we need to alias Volume to the real android::fs_mgr::FstabEntry. In doing so, we need to include <fstab/fstab.h> and this requires libfstab as a library, which a few modules did not have before. Test: treehugger Change-Id: I655209a0efb304b3e0568db0748bd5cf7cecbdb7

2017-11-03Switch to bionic gtest in bootable/recoveryTianjie Xu1-16/+17
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/+7
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.

2017-03-27Revert "libbootloader_message: use different fstab paths for normal/recovery boot"Bowgo Tsai1-8/+2
This reverts commit 37bd44174bf2511320961f3f8cd1f698a1c72b66. The logic here is better to be moved into fs_mgr, not fs_mgr clients.

2017-03-25libbootloader_message: use different fstab paths for normal/recovery bootBowgo Tsai1-2/+8
libbootloader_message is used by both normal boot and recovery boot. It needs to use different fstab paths, respectively. Otherwise, factory reset will fail when we move /fstab.{ro.hardware} to /vendor/etc/. Recovery boot: fs_mgr_read_fstab_with_dt("/etc/recovery.fstab") Normal boot: fs_mgr_read_fstab_default() Bug: 35811655 Bug: 36502022 Test: normal boot sailfish, go to Settings > System & tap on "Factory Data reset" Test: recovery boot sailfish Change-Id: I253f5bdfb9be8a01f80856eb1194f85cdf992bbd
2017-03-10recovery: replacing fs_mgr_read_fstab() with new fs_mgr APIsBowgo Tsai1-18/+5
The fstab settings of early-mounted partitions (e.g., /vendor) will be in kernel device tree. Switch to the new API to get the whole settings with those in device tree: fs_mgr_read_fstab_with_dt("/etc/recovery.fstab") The original default /fstab.{ro.hardware} might be moved to /vendor/etc/. or /odm/etc/. Use another new API to get the default fstab instead of using the hard-coded /fstab.{ro.hardware}. This API also includes the settings from device tree: fs_mgr_read_fstab_default() Bug: 35811655 Test: boot sailfish recovery Change-Id: Iaa56ac7f7b4c4dfc7180c65f03e9a37b94f1de09
2016-12-15Add update_bootloader_message() to fix two-step OTAs.Tao Bao1-0/+21
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
