Subject: [PATCH] DO NOT MERGE Dismiss keyguard when simpin auth'd and...
security method is none. This is mostly to fix the case where we auth
sim pin in the set up wizard and it goes straight to keyguard instead of
the setup wizard activity.
This works with the prevent bypass keyguard flag because the device
should be noe secure in this case.
Fixes: 222446076
Test: turn locked sim on, which opens the sim pin screen. Auth the
screen and observe that keyguard is not shown.

Subject: [PATCH] Truncate user data to a limit of 500 characters
Fix vulnerability that allows creating users with no restrictions. This is done by creating an intent to create a user and putting extras that are too long to be serialized. It causes IOException and the restrictions are not written in the file.
By truncating the string values when writing them to the file, we ensure that the exception does not happen and it can be recorded correctly.
Bug: 293602317
Test: install app provided in the bug, open app and click add. Check logcat to see there is no more IOException. Reboot the device by either opening User details page or running adb shell dumpsys user | grep -A12 heen and see that the restrictions are in place.

Subject: [PATCH] RESTRICT AUTOMERGE Log to detect usage of whitelistToken when
sending non-PI target
Log ActivityManagerService.sendIntentSender if the target is not a
PendingIntent and a non-null whitelistToken is sent to the client.
This is simply to detect if there are real cases this would happen
before we decide simply remove whitelistToken in that case.
Do not pass whitelistToken when sending non-PI target
In ActivityManagerService.sendIntentSender, if the target is not a
PendingIntent, do not send whitelistToken to the client.
Bug: 279428283

Subject: [PATCH] Fix some OOB errors in BTM parsing
Some HCI BLE events are missing bounds checks, leading to possible OOB
access. Add the appropriate bounds checks on the packets.
Bug: 279169188
Test: atest bluetooth_test_gd_unit, net_test_stack_btm
Tag: #security
Ignore-AOSP-First: Security
(cherry picked from https://googleplex-android-review.googlesource.com/q/commit:949eb6b355f1bdcfb5567ebe1b7f00a61b6fb066)
Merged-In: Icf2953c687d9c4e2ca9629474151b8deab6c5f57
