  3. Pass in source slot to ctor of dynamic control 

    When DynamicPartitionControlAndroid is constructed, it initializes both
source and target slot to -1. These values get updated during
PreparePartitionsForUpdate call. And we only
PreparePartitionsForUpdate() when applying an OTA or applocating space
for an OTA(not when verifying OTA metadata). Which means if
VerifyPayloadApplicable() is called before any call two other APIs, we
could be using an "Uninitialiazed"  dynamic partition control.

To mitigate this problem, we pass in source_slot at ctor of
DynamicPartitionControl, also make IsDynamicPartition() api take in a
slot number to avoid reading uninitialized member fields.

Bug: 181643302

Test: apply an OTA, abort, restart update_engine, verify a payload

  1. Allow /postinstall files to have custom contexts 

    We were mounting /postinstall with a 'context=...' option. This forces
all files within /postinstall to have a single selinux context,
limiting the possible granularity of our policies. Here we change it
to simply default to the 'postinstall_file' context for the 'system'
partition but allow individual files to have their own custom contexts
defined by /system/sepolicy. Other partitions retain the single
'postinstall_file' context.

The sample_images were updated to manually add a selinux label for
testing FS contexts.

  1. Check the super partiton size in VAB case 

    When the snapshot is used, we should check that the maximum size
of all dynamic partition groups doesn't exceed the super partition
size.

  2. Allow /postinstall files to have custom contexts 

    We were mounting /postinstall with a 'context=...' option. This forces
all files within /postinstall to have a single selinux context,
limiting the possible granularity of our policies. Here we change it
to simply default to the 'postinstall_file' context for the 'system'
partition but allow individual files to have their own custom contexts
defined by /system/sepolicy. Other partitions retain the single
'postinstall_file' context.

The sample_images were updated to manually add a selinux label for
testing FS contexts.

Test: Manual OTA of blueline
Test: atest update_engine_unittests

  1. Add 5s timeout to cleanup commands 

    Sometimes shutdown takes a while due to adb issues, gracefully terminate
with a timeout. This will throw an exception if timeout occured, telling
the developer that something went wrong.

  1. CheckSuperPartitionAllocatableSpace: based on device prop 

    Check allocatable space in super based on whether VAB is
enabled on the device, instead of basing on whether snapshot
is used for this update.

On VAB devices where snapshot is not used, e.g. secondary
update, we don't want to divide allocatable space by half.

The logic changes from:

  if (!retrofit DAP && ! update uses snapshot && !sideload)
    allocatable_space /= 2

to

  if (!retrofit DAP && ! VAB enabled)
    allocatable_space /= 2

All other changes are cosmetic.

  4. Refactor extent writer to take filedescriptor in constructor 

    Functions which receive an instance of extent writer need to manually
pass fd to ExtentWriter via Init() call, which breaks separation of
concerns. It makes it hard for us to decouple InstallOp execution from
writing of data, as the execution unit must be aware of which fd to pass
to extent writer. In addition, many extents writer, such as snapshot
extent writer, simply ignores the fd parameter, which is a indication of
poor code structure.

To address the above issue, we pass FileDescriptorPtr via constructor if
needed. This way, whoever is "executing" InstallOps don't need to care
about where the output data is going, and whoever's writing the data
would be responsible for initializing an ExtentWriter.

  2. Add COW version to the update_metadata.proto 

    COW versioning will be used to detect if the COW library
version matches with the version in the proto file.
If not, VABC is disabled.

Bug: 183863613
Test: Apply OTA and verifiy if VABC is disabled if the versioning
doesn't match

    When postinstall_mount_device is initially introduced, it's only
intended to be used by postinstall action, hence  the name. Now we plan
to use it for fs verification purpose as well, rename for better
clarity.

  1. Fix verity discarded bug 

    If update_engine opens CowWriterFileDescriptor w/o writing anything,
data past the resume label is readable while fd is open, but will
be discarded once the fd is closed. Such "phantom read" causes
inconsistency. This CL contains two changes to address the above bug:

1. When device reboots after update, all I/O are served by snapuserd.
update_engine should use snapuserd for verification to emulate bahvior
of device after reboot.

2. When a CowWriterFd is opened, don't call Finalize() if no verity is
written. Since past-the-end data is discarded when we call Finalize()

  2. Create a minimal testcase to reproduce silent verity corruption 

    b/186196758 is triggered by the following sequence of events:

1. update_engine finish writing all install ops, emits kEndOfInstall
label
2. update_engine opens cow in append mode, invokes
InitialiazeAppend(kEndOfInstall)
3. update_engine writes verity data, invokes SnapshotWriter::Finalize()
4. update_engine repeats step 2, but does not write any data after
opening SnapshotWriter. Instead, it reads verity and make sure the hash
matches what's specified in OTA payload.
5. Reboot device, verity data corrupted, device rollback to slot _a.

This is because, during step 4, when calling
InitializeAppend(kEndOfInstall), the SnapshotWriter only reads up to the
given label. But OpenReader() completely disregards the resume label and
reads all ops. Therefore, update_engine sees the verity data, and
determines that everything is fine. However, when calling
SnapshotWriter::Finalize(), data after resume label are discarded,
therefore verity data is gone.

  3. Write verity first, then do fs verification 

    Old behavior:
   Read partition, for each block:
    Update hasher
    Update verity writer
   before reading hashtree/verity:
    write hashtree/verity to disk
   Read the last verity blocks.
   Finalize hasher, verity hashes.

The old bahvior tries to minimize fs read by only read once and feed
data to hasher and verity writer. However, in VABC, reading/writing are
handled very differently. Read can be done via regular fd, but writes
must go through special COW API. As we have seen in b/186196758, using
COW API in filesystem hashing can lead to inconsistent read and boot
failure. Therefore, we've decided to write verity first using COW API,
then read/hash partition using regular fd. This does mean that we need
to read everything twice, but we think this is a worth while tradeoff.
As verity writes can take 5 minutes, but reading the entire partition
again only takes <10 seconds.

New behavior:
    Read partition, for each block:
      Update verity writer
    Finalize verity writer, write verity to disk
    launch snapuserd, open a regular fd.
    Read partition, for each block:
      Update hasher
    Finaliaze hasher, verity hashes.

  3. ResetStatus if update_engine boot in different slot but same build 

    Old behavior:
    When update_engine starts up after device take OTA and reboot, if
    device booted into a different build(check build fingerprint),
    ResetStatus().

When we apply a self-ota, device will boot into the same build, so
ResetStatus() is never called. If we apply the same OTA at this point,
this OTA will be treated as a "resume", and will fail to install because
we never call libsnapshot's API to allocate snapshot for new update.

Changed to ResetStatus() if boot slot changed, or build fingerprint
changed.

Bug: 185019674
Test: apply self-full OTA, reboot, repeat 2 times.

  1. Clean up reserved space for decompression when OTA cancelled 

    OTA can terminate in the following ways:

1) Before reboot, intentionally cancelled.
2) Before reboot, failed due to error
3) After reboot, failed due to error
4) After reboot, success

Cleaning up from ResetStatus should cover #1. For #2, there won't be
automatic cleanup on failure, as sometimes we resume OTA from where it
last failed. So user needs to explicitely call ResetStatus to clean up.
for #2.

Number #3 and #4 will be dealt in follow up cl.

Bug: 172911822
Test: Case #1: Intentionally cancel
  1. Allocated space:
     python3 update_device.py --allocate-only ota.zip
  2. Temp file deleted by:
     adb shell update_engine_client --reset_status

  2. Record the source build fingerprint in SnapshotMergeStats. 

    This also adds a manual call to WriteState(). If update_engine crashes
or the device reboots, it's possible that certain stats (such as the COW
file stats) will be gone by the time the merge state is recovered.
Forcing a write prevents this.

Note that the write was previously implicit in set_cow_file_size, but is
now explicit before calling InitiateMerge().

  1. update_engine: allow allocatable space to be overridden 

    The override is needed in cases where update_engine erroneously concludes that there isn't sufficient space for dynamic partitions.

This prevents some ROMs from being flashed. This patch allows the available space to be overridden, via a prop (ro.dynamic.full_size).

In a typical situation where this problem occurs, you will see something like this in the recovery log:
'update_engine_sideload E 12-17 04:06:00   809   809 [ERROR:dynamic_partition_control_android.cc(830)]
The maximum size of all groups for the target slot (9126805504) has exceeded allocatable space for dynamic partitions 9125756928'

So, update_engine has used a calculation of the allocatable space that doesn't match the actual available space.

In this example, running "resetprop ro.dynamic.full_size 9126805504" via runatboot.sh or postrecoveryboot.sh will override the allocatable space and allow the ROM to flash.

If the prop is used, the override will only be triggered if the value supplied is higher than the calculated allocatable space.

If the prop is not used at all, then everything will carry on as normal.
