Camera3Device's mId can be accessed from String& after being freed with

Subject: [PATCH] Fix incorrect buffer size in NuPlayer
This was discovered from running GTS tests that were failing because the
DRM implementation was receiving media packets of incorrect sizes for
decryption. The problem is that it was copying content using the size of
the underlying MediaBuffer object rather than the range that was set in
it. That was leading to lots of trailing garbage in media packets.
Generally this was fine and decoders would ignore them, but recent
changes in decryption handling for AMD platforms exposed this problem.
The fix is very straightforward in that we should be using the
range_length rather than the size when copying them. This doesn't impact
non-DRM content as those buffer sizes appear to be correct already based
on testing.
Bug: b:268158584
Test: gts.MediaPlayerTest#testLLAMA_H264_BASELINE_240P_800_DOWNLOADED_V1_ASYNC
no longer shows corruption on guybrush and packet sizes now match
up as expected

Subject: [PATCH] RingtoneManager: verify default ringtone is audio
When a ringtone picker tries to set a ringtone through
RingtoneManager.setActualDefaultRingtoneUri (also
called by com.android.settings.DefaultRingtonePreference),
verify the mimeType can be obtained (not found when caller
doesn't have access to it) and it is an audio resource.

Subject: [PATCH] [DO NOT MERGE] Verify URI Permissions in Autofill RemoteViews
Check permissions of URI inside of FillResponse's RemoteViews. If the
current user does not have the required permissions to view the URI, the
RemoteView is dropped from displaying.
This fixes a security spill in which a user can view content of another
user through a malicious Autofill provider.
Bug: 283137865
Fixes: b/283264674 b/281666022 b/281665050 b/281848557 b/281533566
b/281534749 b/283101289
Test: Verified by POC app attached in bugs
Test: atest CtsAutoFillServiceTestCases (added new tests)

Subject: [PATCH] RESTRICT AUTOMERGE: SettingsProvider: exclude secure_frp_mode
from resets
When RescueParty detects that a system process is crashing frequently,
it tries to recover in various ways, such as by resetting all settings.
Unfortunately, this included resetting the secure_frp_mode setting,
which is the means by which the system keeps track of whether the
Factory Reset Protection (FRP) challenge has been passed yet. With this
setting reset, some FRP restrictions went away and it became possible to
bypass FRP by setting a new lockscreen credential.
Fix this by excluding secure_frp_mode from resets.
Note: currently this bug isn't reproducible on 'main' due to ag/23727749
disabling much of RescueParty, but that is a temporary change.
Bug: 253043065
Test: With ag/23727749 reverted and with my fix to prevent
com.android.settings from crashing *not* applied, tried repeatedly
setting lockscreen credential while in FRP mode, using the
smartlock setup activity launched by intent via adb. Verified
that although RescueParty is still triggered after 5 attempts,
secure_frp_mode is no longer reset (its value remains "1").
Test: Verified that secure_frp_mode still gets changed from 1 to 0 when
FRP is passed legitimately.

Test: atest android.provider.SettingsProviderTest
(cherry picked from commit 9890dd7f15c091f7d1a09e4fddb9f85d32015955)
(changed Global.SECURE_FRP_MODE to Secure.SECURE_FRP_MODE,
needed because this setting was moved in U)
(removed static keyword from shouldExcludeSettingFromReset(),
needed for compatibility with Java 15 and earlier)

When p_buf->len is mtu - 1 and p_cmd->multi_req.variable_len
evaluates to true, integer underflow is triggered
in the following line, resulting OOB access.
```
len = p_rsp->attr_value.len - (total_len - mtu);

Subject: [PATCH] Fix path traversal vulnerabilities in MediaProvider
Canonicalize filepath provided by the caller when hanling SCAN_FILE_CALL
method call in MediaProvider.
Additionally, make sure to check access permission in SCAN_FILE_CALL
(using enforceCallingPermissionInternal()).
Preemptively canonicalize Files provided as an arguments to the public
API methods in ModernMediaScanner (scanFile(), scanDirectory() and
onDirectoryDirty()) to prevent path traversal attacks.

Test: atest MediaProviderTests

Subject: [PATCH] Fix for heap-use-after-free in GPUService.cpp
This adds a unit test and fix for the bug reported by libfuzzer.
Changes made:
* Expose GPUService as testable code.
* Update main_gpuservice.cpp to use the new GpuService now located at
gpuservice/GpuService.h
* Make initializer threads members of GpuService
* Join the threads in destructor to prevent heap-use-after-free.
* Add unit test that waits 3 seconds after deallocation to ensure no
wrong access is made.
Bug: 282919145
Test: Added unit test and ran on device with ASAN

Subject: [PATCH] RESTRICT AUTOMERGE: Catch exceptions from setLockCredential()
When LockPatternUtils#setLockCredential() fails, it can either return
false or throw an exception. Catch the exception and treat it the same
way as a false return value, to prevent crashing com.android.settings.
Bug: 253043065
Test: Tried setting lockscreen credential while in secure FRP mode using
smartlock setup activity launched by intent via adb. Verified
that com.android.settings no longer crashes due to the exception
from LockPatternUtils#setLockCredential().
(cherry picked from commit 05f1eff1c9c3f82797f1a0f92ff7665b9f463488)
(moved change into ChooseLockPassword.java and ChooseLockPattern.java,
which are merged into SaveAndFinishWorker.java on udc-qpr-dev and main)

From c873988898e1b520e0e4cfda77e26ec4377a4ce9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix vulnerability in CallRedirectionService.
Currently when the CallRedirectionService binding died, we didn't do
anything, which cause malicious app start activities even not run in the
background by implementing a CallRedirectionService and overriding the
onPlaceCall method to schedule a activity start job in an independent
process and then kill itself. In that way, the activity can still
start after the CallRedirectionService died. Fix this by unbinding the
service when the binding died.
Bug: b/289809991
Test: Using testapp provided in bug to make sure the test activity can't
be started
