Commit 21803d3574 only added compatibility
metadata for A/B OTA packages, because by that time we didn't use
'ro.treble.enabled' property to determine if a target was Treble-enabled.
This CL uses 'ro.treble.enabled' to guard the packing of compatibility
metadata for both of A/B and non-A/B OTA packages. It also switches to
checking the system/vendor fingerprints to determine if there's an
update to the partition (previously it was computing the SHA-1 of the
images, which may have unintentionally changed due to issues that give
non-repetitive builds).
Bug: 64339310
Test: Generate OTA packages (full and incremental) on Treble-enabled
targets (sailfish, as well as a non-A/B angler target with
Treble-enabled locally); check that the compatibility.zip entry
exists.
Test: Generate OTA packages on Treble-unenabled non-A/B target (angler);
check that the compatibility.zip entry doesn't exist.

This entry only exists in non-A/B full OTA path. However, this file has
never been loaded by recovery - recovery was only reading the one from
the recovery image (which also has been removed by a recent change in
[1]).

In BOARD_AVB_MAKE_VBMETA_IMAGE_ARGS, if we have defined
"--include_descriptors_from_image" with an image file whose path points
to source tree, add_img_to_target_files.py or sign_target_files_apks.py
may fail to find the file. Because these scripts may run without a
source tree, by taking target_files.zip as the only input.
This CL scans additional locations in the input target_files.zip to find
those missing files in avb_vbmeta_args. As long as the files are included
in the target_files.zip, they get a second chance to be found.
Bug: 63910867
Test: As follows:
1. Setup BOARD_AVB_MAKE_VBMETA_IMAGE_ARGS with a local file path;
2. Remove the local file;
3. sign_target_files_apks.py fails without this CL;
4. sign_target_files_apks.py works.

(cherry picked from commit 1dc5d47653)
Brotli has a better compression ratio than deflation. So for non-AB
full OTA, we can compress the new.dat with brotli first and store it
in the zip package.
This increase the OTA generation time by ~5 minutes for a full OTA
(measured based on 2.0G system.new.dat)

Radio images are added to INSTALLED_RADIOIMAGE_TARGET, which by default
will be packed under RADIO/ in a target_files zip. This CL introduces
BOARD_PACK_RADIOIMAGES that allows additionally copying them into
IMAGES/, which will then be included into <product>-img.zip.

We should only disallow zip64 for the image and OTA zips (because we
don't have zip64 support in libziparchive yet). But target_files zips
are fine to use zip64 with host tools (and we already do that in
add_img_to_target_files.py).
This CL also sets the default compression method to DEFLATED when
creating the signed TF.zip.
Test: sign_target_files.apks.py signing a large TF.zip passes.

In case the system/vendor image is updated for an A/B target file, we'll
delay the write of META/care_map.txt. Specifically, we'll run "zip -d"
to remove the old entry and then zip in the new one from tmp dir.

Current build system will include AVB metadata from each partition and
store them into /vbmeta partiton when BOARD_AVB_ENABLE is set, which makes
each partition tightly-coupled.
Add the support for 'chain partition':
- The vbmeta of each partition is stored on the same partition itself.
- The public key used to verify each partition is stored in /vbmeta.
For example, the following build variables are required to enable chain
partition for system partition:
- BOARD_AVB_SYSTEM_KEY_PATH := path/to/system_private_key
- BOARD_AVB_SYSTEM_ALGORITHM := SHA512_RSA8192
- BOARD_AVB_SYSTEM_ROLLBACK_INDEX := 1
- BOARD_AVB_SYSTEM_ROLLBACK_INDEX_LOCATION := 2
The corresponding settings will be added into META/misc_info.txt for
build_image.py and/or add_img_to_target_files.py:
- avb_system_key_path=path/to/system_private_key
- avb_system_algorithm=SHA512_RSA8192
- avb_system_add_hashtree_footer_args=--rollback_index 1
- avb_system_rollback_index_location=2
To enable chain partition for other partitions, just replace SYSTEM with
BOOT, VENDOR and/or DTBO in the build variables.
Also switch from `avbtool make_vbmeta_image --setup_rootfs_from_kernel system.img ...`
to `avbtool add_hashtree_footer --image system.img --setup_as_rootfs_from_kernel...`
when BOARD_BUILD_SYSTEM_ROOT_IMAGE is true. This works for both chained
and no-chained:
- chained: `avbtool add_hashtree_footer --setup_as_rootfs_from_kernel` will
add dm-verity kernel cmdline descriptor to system.img
- no-chained: `avbtool make_vbmeta_image --include_descriptors_from_image
system.img` will include the kernel cmdline descriptor from system.img into
vbmeta.img

Currently we're writing META/misc_info.txt to the new TF.zip during
ReplaceVerityPrivateKey(). We should delay that until we have replaced
everything in need. Otherwise we won't be able to replace/overwrite
that zip entry (unless `zip -d` first).
This CL also cleans up the return value of ReplaceVerityPublicKey() and
ReplaceVerityKeyId(), since the caller no longer needs the values.
Test: sign_target_files_apks.py and check the generated signed TF.zip.

board_avb_algorithm and board_avb_key_path are overlapping with
avb_signing_args. In core/Makefile, only avb_signing_args (i.e.
INTERNAL_AVB_SIGNING_ARGS) will be used in the AVB-signing command. It
covers the contents in board_avb_{algorithm,key_path}. We should do the
same thing in tools/releasetools to avoid potential inconsistency.
This CL cleans up the logic in tools/releasetools, by always using
avb_signing_args. This also allows easier signing key replacement (so we
can replace the key/algorithm/signer in 'avb_signing_args').
board_avb_system_add_hashtree_footer_args is unused in releasetools
script, and the same information has been covered by
system_avb_add_hashtree_footer_args. This CL removes this arg as well.
Test: `m dist`. Then a) check the removed three args no longer exist in
META/misc_info.txt; b) check that rebuilding images with
add_img_to_target_files.py uses the same parameters.

When AVB is enabled, generate care_map.txt and add it to the target
files. Also copy it into the OTA package where it will later be used
by the update_verifier.
Bug: 62208947
Test: \
1. Run add_img_to_target_files on the TF of a new pixel device,
and care_map.txt generates successfully.
2. Make dist in oc-dr1-release and find care_map.txt in the OTA package.
3. update_verifier succeeds in reading all the blocks on the care_map,
and fails to read out-of-bound blocks.

This is a step to enable signing a given target_files zip with release
keys.
When calling sign_target_files_apks.py, we will delete all the entries
under IMAGES/ in order to re-generate them (with the proper release
keys). In order to support that, we need to pack everything in need into
TF.zip.
Steps to test the CL.
a) Choose a target that has both AVB and DTBO enabled.
$ m dist
b) Check IMAGES/dtbo.img and PREBUILT_IMAGES/dtbo.img both exist in the
generated out/dist/TF.zip.
c) Remove the entries under IMAGES/ from the generated TF.zip.
$ zip -d TF.zip IMAGES/\*
d) Re-generate the images with TF.zip.
$ build/make/tools/releasetools/add_img_to_target_files.py TF.zip
e) Check that IMAGES/dtbo.img is re-generated, and it's identical to the
image in b). Note that by default the re-generated image will carry a
different footer, because of the random salt. This CL is verified by
specifying the same salt.
