* Clear the warm_reset flag after boot is successfulTianjie Xu2019-11-151-0/+4
| | | | | | | | | | | | The property is set to inform kernel to do a warm_reset on the next reboot. This is useful to persist the logs to debug device boot failures. After the slot has been marked as boot successful, we can drop the warm_reset flag to avoid the performance overhead on the next reboot.

| * Update_verifier: Remove the support for legacy text format CareMapxunchang2019-03-132-47/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have already switched to the protobuf format for new builds, and the downgrade packages will require a data wipe. So it should be safe to drop the support for text format. This also helps to save the issue when users sideload a package with a pending OTA, because the new CareMap contains the fingerprint of the intended build. Bug: 128536706 Test: unit tests pass, run update_verifier with legacy CareMap Change-Id: I1c4d0e54ec591f16cc0a65dac76767725ff9e7c4

* Defer marking boot successful when checkpointingDaniel Rosenberg2019-02-072-6/+31
| | | | | | | | | | | | | | This moves actually marking the slot as successful to a later point so that on devices with checkpointing enabled we can still roll back to the previous version if we fail to boot to the point that the checkpoint is marked as successful. Test: When taking an update on a checkpoint enabled device, it defers marking the slot as successful instead of directly marking it. Visible in logs. Bug: 123260515 Change-Id: I7ed3595c1b0904ddbfe20d1cad4f69ecbf1ea351
* Compare the fingerprint before reading the partitionTianjie Xu2018-10-052-14/+53
| | | | | | | | | | | | The update_verifier now compares the fingerprint of a partition before performing the blocks read. If the fingerprint of the current system property mismatches the one embedded in the care_map, verification of this partition will be skipped. This is useful for the possible system only updates in the future. Bug: 114778109 Test: unit tests pass Change-Id: Iea309148a05109b5810dfb533d94260d77ab8540

* Refactor update_verifier into a classTianjie Xu2018-09-214-72/+135
| | | | | | | | | | | | | The refactor separates out the parsing of care_map and the actual verification of the partitions. Moreover, it skips the verification in case of a format error in the care map. Also, the parsing of care_map now uses the suffix of the file to tell if it has the protobuf format or the plain text format. Bug: 115740187 Test: unit test pass Change-Id: I7aa32004db02af1deb7bfdc6f5bd7921eb7883e5
* Add a python binary to generate the protobuf for care_mapTianjie Xu2018-08-172-1/+140
| | | | | | | | | | | | | | This binary parses the legacy care_map text in the input file and writes the generated protobuf message into the output file. For test purpose, it also has a "--parse_proto" option to reverse the process and convert a protobuf message file into plain text. The build script will then call the binary to generate the care_map.txt in the new format. Bug: 77867897 Test: Run the binary to convert a care_map.txt, run update_verifier Change-Id: I3ca65e19027404806132aa8d51e9bff766630c99
* Add proto3 support for care_mapTianjie Xu2018-07-254-25/+95
| | | | | | | | | | Switching to the protobuf format helps to make the care_map more extensible. As we have such plans in the future, add the support to parse the protobuf message in the update_verifier. Bug: 77867897 Test: unit tests pass, update_verifier successfully verifies a care_map.pb Change-Id: I9fe83cb4dd3cc8d6fd0260f2a47338fe142d3938

* Make update_verifier generic across verified boot versions.Tao Bao2018-04-202-35/+18
| | | | | | | | | | | | | | | This allows the update_verifier in a general system image to work across devices that have different verified boot versions (i.e. not supported / verified boot 1.0 / verified boot 2.0 / disabled). Bug: 78283982 Test: Run recovery_component_test on both of marlin and walleye. Test: Generate an OTA that has this CL. Install this OTA and check the update_verifier log during the post-reboot verification, on both of marlin (VB 1.0) and walleye (VB 2.0). Test: Build and flash walleye image with verified boot disabled. Check that update_verifier marks the slot as successfully booted. Change-Id: I828d87d59f911786531f774ffcf9b2ad7c2ca007
* update_verifier: Support verifying product partition.Tao Bao2018-03-231-12/+10
| | | | | | | | | | | | | | We have added the support for building /product partition in build system (the CL in [1]), where /product is an optional partition that contains system files. This CL adds the matching support if /product needs to be verified during A/B OTA (i.e. listed in care_map file). [1]: commit b7735d81054002961b681f4bdf296d4de2701135, https://android-review.googlesource.com/c/platform/build/+/598454 Bug: 63974895 Test: Run update_verifier test on walleye.

* update_verifier: Fix the wrong computation with group_range_count.Tao Bao2017-10-291-3/+5
| | | | | | | | | | | | | | | | 'group_range_count' doesn't properly consider the pair-wise range structure. It may split the ranges into wrong pairs if it evaluates to an odd number. For example, for an input range string of "6,0,2,10,12,20,22" with 4 threads, group_range_count becomes 1. It would then try to verify (0,2), (2,10), (10,12) and (12,20). Note that (2,10) and (12,20) are not valid ranges to be verified, and with (20,22) uncovered. Bug: 68343761 Test: Trigger update_verifier verification.

* update_verifier: Support androidboot.veritymode being empty or 'disabled'.David Zeuthen2017-08-081-4/+17
| | | | | | | | | | | | | Bootloaders using libavb will set androidboot.veritymode=disabled if the "disable dm-verity" flag has been set. Additionally if the "disable verification" flag is set androidboot.veritymode will not be set at all. Handle both cases. Without this fix we'll end up in a bootloop. Test: Manually tested on a device using AVB. Bug: 64315394 Change-Id: I8310849e347248f4a96158838310f688ecef4211
* update_verifier: Handle legacy care_map.txt gracefully.Tao Bao2017-07-221-29/+42
| | | | | | | | | | | | | | | | | | | | | | | | update_verifier should be backward compatible to not reject legacy care_map.txt from old releases, which could otherwise fail to boot into the new release. For example, we've changed the care_map format between N and O. An O update_verifier would fail to work with an N care_map.txt - a) we have switched update_verifier to read from device mapper in O; b) the last few blocks that contain metadata can't be read via device mapper. This could be a result of sideloading an O OTA while the device having a pending N update. Bug: 63544345 Test: As follows on sailfish: 1. Flash the device with this CL; 2. Put a copy of N care_map.txt at /data/ota_package/. Restore the permissions properly ('cache' group); 3. `adb reboot bootloader`; 4. `fastboot set_active <current_slot>` 5. Device boots up into home screen, with a warning in logcat that says it has skipped legacy care_map.txt. Change-Id: I6acc88c9e655a9245e6531f176fef7953953935f

* Add update_verifier for A/B OTA update.Tao Bao2015-12-082-0/+108
update_verifier checks the integrity of the updated system and vendor partitions on the first boot post an A/B OTA update. It marks the current slot as having booted successfully if it passes the verification. This CL doesn't perform any actual verification work which will be addressed in follow-up CLs.
