* From android-11, recovery warns the user about the danger of
rebooting after a failed update, but if we didn't even start
the install procedure it doesn't really make much sense.

When entering recovery via rescue party, recovery does not call
FinishRecovery() to reset BCB. This causes the rescue party command to
stick, and device keeps rebooting into rescue party mode after entering
bootloader mode and reboot.
Test: enter rescue party, reboot bootloader, fastboot reboot

For 16K dev options, we might need to reformat /data partition as ext4
before enabling the feature. Add necessary support to recovery.
Test: Trigger reboot with --wipe_data --reformat_data=ext4, make sure
/data is reformatted with ext4 on next boot

This allows us to erase the system image without resetting the MTE
state. This is useful for TestHarness looking to re-use an MTE enabled
device without incurring an extra reboot to re-enable after reboot.

Devices that launched with Android 10 or later require FBE (File Based
Encryption) from the beginning, so there's no need to support converting
to FBE after the fact anymore. This was only ever a developer option,
so it probably wasn't used much. And in any case, it's not used
anymore, as isConvertibleToFBE() is hard-coded to return false. Besides
the fact that FBE has been required for several releases now, this
functionality was only ever available on devices that use FDE (Full Disk
Encryption), but FDE support has been removed from Android.
Therefore, remove this unused code.

Normally, if an ota package has --wipe_user_data flag, we set bootloader
parameter --wipe_data, so that next boot into bootloader will wipe
userdata. But this doesn't work in recovery, likely because after
recovery we don't reboot to bootloader, but directly boot into android.
Therefore perform data reset in recovery if the OTA package has
POWERWASH flag.
Bug: 203507329
Test: apply an OTA pkg with --wipe_user_data, verify that data wipe
happened

ro.bootimage.* sysprops will be removed as they are redundant. Read
ro.build.fingerprint instead.
This is safe because:
2) ro.bootimage.build.fingerprint is the same as other
ro.<partition>.build.fingerprint all of which are from
$(BUILD_FINGERPRINT_FILE).
3) BUILD_FINGERPRINT_FILE is composed of PRODUCT_BRAND, TARGET_PRODUCT,
TARGET_DEVICE, etc.
4) ro.build.fingerprint is auto-composed by init at runtime by the same
rule as #3.

The non-A/B package installation is subject to TOC/TOU flaw if the
attacker can switch the package in the middle of installation. And the
most pratical case is to store the package on an external device, e.g. a
sdcard, and swap the device in the middle.
To prevent that, we can adopt the same protection as used in sideloading
a package with FUSE. Specifically, when we install the package with FUSE,
we read the entire package to cryptographically verify its signature.
The hash for each transfer block is recorded in the memory (TOC), and
the subsequent reads (TOU) will be rejected upon dectecting a mismatch.
This CL forces the package installation with FUSE when the package stays
on a removable media.

For non A/B and Virtual A/B devices where sideloading may affect

prompt do not show up.

A number of utility functions are intended for serving recovery's own
use. Exposing them via libotautil (which is a static lib) would pass the
dependencies onto libotautil's users (e.g. recovery image, updater, host
simulator, device-specific recovery UI/updater extensions etc). This CL
finds a new home for the utils that are private to recovery.
Test: mmma bootable/recovery

We may fail to memory map the package on 32 bit builds for packages with
2GiB+ size. This cl tries to install the package with fuse when memory map
fails in such cases.

the corresponding update_package argument.

Factor out a new function from ApplyFromSdcard that installs a package
from a local path. Inside this function, we start the fuse and choose the
type of data provider depending on the path string. And similar to the
existing logic, we treat the package as a block map if the path starts
with a '@'.
This is part of the effort to install larger than 2GiB packages on ILP32
devices.

This CL changes the on-screen UI to display the default image while
