2017-11-02update_verifier: Fix the wrong computation with group_range_count.Tao Bao1-3/+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. Check the number of verified blocks against the one in care_map.txt.

2017-08-09update_verifier: verify blocks in parallelWei Wang1-31/+51
This CL is to change update_verifier to verify blocks in parallel to maximize storage bandwidth, it also preallocate the buffer to avoid vector allocation within reading loop.

2017-08-09update_verifier: Support androidboot.veritymode being empty or 'disabled'.David Zeuthen1-4/+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. (cherry-picked from commit 1a0929cc8aac532dba00b3c98cea22715719a421) Bug: 64404283 Change-Id: I3adf93f8dfd528fe9b869a63afa775f5730a3f69
2017-07-24update_verifier: Handle legacy care_map.txt gracefully.Tao Bao1-29/+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.

2015-12-08Add update_verifier for A/B OTA update.Tao Bao2-0/+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.
