d987e9b327 Migrate Test Targets to New Android Ownership Model
This CL is created as a best effort to migrate test targets to the new Android ownership model.
It is based on historical data from repository history and insights from git blame.
Given the nature of this effort, there may be instances of incorrect attribution. If you find incorrect or unnecessary
attribution in this CL, please create a new CL to fix that.

940820cfa1 Replace use of deprecated logging functions
This is needed to upgrade the android_logger crate from 0.12.0
to 0.13.3.

with_max_level provides the same functionality as with_min_level.
The renaming is admittedly confusing, but the new name is accurate
and it makes sense that they deprecated and then removed the
previously poorly named with_min_level.

See crate documentation [1] and code [2].

07fec0ff0c Deprecating the aidl for Android Protected Confirmation
Android Protected Confirmation is deprecated due to the high
support/maintenance cost for Android device makers and low adoption rate
among app developers. APC requires Android device makers to have a
substantial amount of device-specific UI code running in the trusted
execution environment. That has proven to be expensive to maintain and
non-scalable, as there cannot be a single implementations device makers
can share or use as a reference. Additionally, app developers have not
adopted this feature, as the Android platform offers other mechanisms
for authentication a user's intent. These mechanisms, such as
authentication-bound Keystore keys, are less secure than Trusted UI, but
are more wide-spread. While we explore alternatives to APC that are
viable to the device makers ecosystem, we sunset the APC API.

4dc27b52eb List apps affected by secure user ID
Add a method to the Keystore maintenance interface to list the UIDs of
apps that are affected by a given secure user ID.

With this method, it would be possible to tell if removing a given
user's LSKF or enrolling new biometrics will invalidate Keystore keys,
thus affecting some apps.

6946daa1ab Fix UnlockedDeviceRequired with weak unlock methods
Starting in Android 12, unlocking the device with a class 1
("convenience") biometric, class 2 ("weak") biometric, or a trust agent
unexpectedly doesn't allow the use of UnlockedDeviceRequired keys.  The
cause of this bug is that the cryptographic protection that Keystore now
applies to UnlockedDeviceRequired keys incorrectly assumes that the
device can only be unlocked using LSKF or via a biometric that
participates in Keystore (has a SID and uses HardwareAuthTokens).
Actually, Keyguard also allows the device to be unlocked using weaker
biometrics that do not particiate in Keystore, if they are enrolled.
Similarly, there are also cases where a trust agent can actively unlock
the device, e.g. unlocking a phone using a paired watch.

In combination with the system_server changes in
I34dc49f1338e94755e96c1cf84de0638dc70d311, this CL fixes the bug by
making Keystore retain the UnlockedDeviceRequired super keys in memory
if a weak unlock method is enabled at device lock time.  This does mean
that UnlockedDeviceRequired is enforced only logically when a weak
unlock method is enabled, but this is the best we can do in this case.

This CL also adds methods by which Keystore can be notified of the
expiration of unlock methods, causing the security level of
UnlockedDeviceRequired keys to be upgraded.  A future CL for
system_server is planned to use these.

74b6c752da keystore: remove unused Keystore1 files
Remove files from the "keystore" directory that are unused, i.e. not
referenced by an Android.bp, or in the case of header files not included
from anywhere.  This mostly includes files belonging to Keystore1 that
were missed when Keystore1 was deleted.  This also includes a couple
outdated test scripts that were never actually wired up to anything.

b9c88c9c9e keystore: remove misleading error message from AES_gcm_decrypt()
Since there's now a case where AES_gcm_decrypt() is expected to fail
(trying to use HKDF-derived key to decrypt an old super key that's
encrypted by an PBKDF2-derived key, before falling back to PBKDF2),
remove the corresponding error message from the C++ function.  The error
message is misleading in this case.  In other cases, the error message
does not provide useful information since it seems to be the only way
that AES_gcm_decrypt() can actually fail (seeing as the length mismatch
should never happen), and the caller uses the boolean return value to
create the real Rust error which is then logged/handled appropriately.

Bug: 296464083
Bug: 314391626
Test: Verified that on device that has old super keys, the
      "Failed to decrypt blob" message is no longer logged.

6e5ccd7f4a keystore: eliminate redundant key stretching
Since the Keystore password is a high-entropy synthetic password, key
stretching is not required.  Therefore, improve the performance of
encrypting and decrypting Keystore user super keys by using HKDF instead
of 8192-iteration PBKDF2.  PBKDF2 continues to be used for decrypting
old keys, when AES-GCM decryption using the HKDF-derived key fails.

2202fcc19f Increase RLIMIT_MEMLOCK for keystore2
By default Android only allows processes to lock up to 65536 bytes of
memory, resulting from the command 'setrlimit memlock 65536 65536' in
system/core/rootdir/init.rc.  The recent Keystore changes to create each
user's super keys at user creation time cause Keystore to sometimes lock
more memory and sometimes exceed this limit.  To reproduce this issue
myself, I had to create almost 100 users.  However, it apparently can
happen with fewer users too, based on CTS test failure report.

Fix this issue by setting the memlock limit for keystore2 to unlimited.
Note that the amount actually used remains fairly small, but I don't
think there's a reason to set an arbitrary limit here.  A memlock limit
makes sense for unprivileged apps but not for system processes.

10afa966fa Split Keystore's onLockScreenEvent into onDevice{Unlocked,Locked}
Currently Keystore is notified of the device being unlocked and locked
for each user via onLockScreenEvent(lockScreenEvent, userId, password,
unlockingSids), where lockScreenEvent is UNLOCK or LOCK.  This is a bit
confusing because the password parameter is only meaningful for UNLOCK,
and the unlockingSids parameter is only meaningful for LOCK.  This
problem will get worse when we add a parameter that tells Keystore
whether unlocking via a weak biometric or trust agent is possible, as
that will be another parameter that is only meaningful for LOCK.

Therefore, this CL splits onLockScreenEvent into two methods
onDeviceUnlocked and onDeviceLocked, each with the appropriate
parameters.  No change in behavior intended.
