Subject: [PATCH] DO NOT MERGE Grant carrier privileges if package has carrier
|
||
|
|
config access.
|
||
|
|
|
||
|
|
TelephonyManager#hasCarrierPrivileges internally uses
|
||
|
|
SubscriptionManager#canManageSubscription to decide whether to grant
|
||
|
|
carrier privilege status to an app or not.
|
||
|
|
SubscriptionManager#canManageSubscription returns true if caller APK's
|
||
|
|
certificate matches with one of the mNativeAccessRules or
|
||
|
|
mCarrierConfigAccessRules. This over-grants carrier privilege status
|
||
|
|
to apps that only has mNativeAccessRules.
|
||
|
|
Carrier privilege status should
|
||
|
|
be granted to the caller APK only if it's certificate matches with one
|
||
|
|
of mCarrierConfigAccessRules.
|
||
|
|
Replaced SubscriptionManager#canManageSubscription with
|
||
|
|
PhoneInterfaceManager#hasCarrierConfigAccess which returns true only if
|
||
|
|
caller APK certificates matches with one of mCarrierConfigAccessRules of
|
||
|
|
the given subscription.
