Subject: [PATCH] Add caller check to com.android.credentials.RESET [Backport]
|
|
|
|
* Only the Settings app can reset credentials
|
|
via com.android.credentials.RESET.
|
|
* com.android.credentials.INSTALL should still be
|
|
callable by CertInstaller.
|
|
|
|
Manual testing steps:
|
|
* Install certificate via Settings
|
|
* Verify unable to reset certificates via test app
|
|
provided in the bug (app-debug.apk)
|
|
* Verify able to reset certificates via Settings
|
|
* Verify com.android.credentials.INSTALL isn't changed
|
|
|
|
Bug: 200164168
|
|
Test: manual
