b418c30e3a Skip checking files that have less blocks in block map.
When creating ext4 images with mke2fs, it may skip allocating some
blocks if they contain all zeros. As a result, there could be less
blocks listed in the block map than the actual file length.

For example, for a file with a length of 112200-byte (27+ blocks),
the listed blocks in block.map could be '43665-43688' (24 blocks).
Because some all-zero blocks are not taking actual space.

The generated ext4 images are perfectly valid - kernel will figure out
that data block is not allocated and writes all zeros into user buffer.
However, we can't fully reconstruct a file from its block list in our
Python script. Ideally this can be avoided by mounting or parsing an
ext4 image directly, which is yet to be supported in our script.

This CL skips checking for such files to avoid failing
validate_target_files.py.

Bug: 65213616
Test: validate_target_files.py passes on targets with mke2fs generated
      images (e.g. marlin).

bcd1d161e8 Add compatibility metadata for Treble-enabled non-A/B OTA packages.
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.

9a5f419ecf Look for non-existent files listed in avb_vbmeta_args.
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.

b0a29ad8c2 Generate brotli compressed {}.new.dat for full OTA
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)

c218a470fb Support replacing AVB signing keys.
sign_target_files_apks.py now supports signing targets using verified
boot 2.0 (aka AVB). It allows replacing AVB signing keys for both of
chained and non-chained partitions.

An example command line looks as follows.
 $ ./build/tools/releasetools/sign_target_files_apks.py \
     --avb_vbmeta_key external/avb/test/data/testkey_rsa2048.pem \
     --avb_vbmeta_algorithm SHA256_RSA2048 \
     --avb_vbmeta_extra_args \
         "--signing_helper_with_files ./signing-helper.sh" \
     --avb_system_key external/avb/test/data/testkey_rsa4096.pem \
     --avb_system_algorithm SHA256_RSA4096 \
     --avb_system_extra_args \
         "--signing_helper_with_files ./signing-helper.sh" \
     product-target_files.eng.zip signed-product-target_files.zip

To verify the signed images:
 $ unzip signed-product-target_files.zip IMAGES/\*
 $ avbtool verify_image --image IMAGES/vbmeta.img \
     --expected_chain_partition system:1:testkey_rsa4096_pub.pem \

57ae9a2234 Delay the write-back of misc_info in sign_target_files_apks.py.
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.

f636a80888 AVB: support chain partition signing
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...`

2b8f489e30 Allow sign_target_files_apks.py to create zip64 signed TF.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.

9ac4cb0984 Fix duplicate 'META/care_map.txt' when calling add_img_to_target_files
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.

Bug: 62345693
Test: Run add_img_to_target_files.py on sailfish target files, and
care_map.txt is updated.

3e599ead66 AVB: support chain partition signing
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

46a5999a02 Delay the write-back of misc_info in sign_target_files_apks.py.
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.
