From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: inthewaves Date: Sat, 12 Sep 2020 12:28:34 -0700 Subject: [PATCH] support new special runtime permissions These are treated as a runtime permission even for legacy apps. They need to be granted by default for all apps to maintain compatibility. Ported from 10: 4d5d82f4e2fb9ff68158bf30f3944591bb74dd04 Changes from 10: - It seems like parts of PackageManagerService#resetUserChangesToRuntimePermissionsAndFlagsLPw were refactored into PermissionManagerService#resetRuntimePermissionsInternal. As a result, PackageManagerService is no longer modified. --- .../permission/PermissionManagerService.java | 24 +++++++++++++++---- 1 file changed, 19 insertions(+), 5 deletions(-) diff --git a/services/core/java/com/android/server/pm/permission/PermissionManagerService.java b/services/core/java/com/android/server/pm/permission/PermissionManagerService.java index 8d2363b6e831..26b959879084 100644 --- a/services/core/java/com/android/server/pm/permission/PermissionManagerService.java +++ b/services/core/java/com/android/server/pm/permission/PermissionManagerService.java @@ -1461,7 +1461,7 @@ public class PermissionManagerService extends IPermissionManager.Stub { // to keep the review required permission flag per user while an // install permission's state is shared across all users. if (pkg.getTargetSdkVersion() < Build.VERSION_CODES.M - && bp.isRuntime()) { + && bp.isRuntime() && !isSpecialRuntimePermission(permName)) { return; } @@ -1513,7 +1513,8 @@ public class PermissionManagerService extends IPermissionManager.Stub { + permName + " for package " + packageName); } - if (pkg.getTargetSdkVersion() < Build.VERSION_CODES.M) { + if (pkg.getTargetSdkVersion() < Build.VERSION_CODES.M + && !isSpecialRuntimePermission(permName)) { Slog.w(TAG, "Cannot grant runtime permission to a legacy app"); return; } @@ -1623,7 +1624,7 @@ public class PermissionManagerService extends IPermissionManager.Stub { // to keep the review required permission flag per user while an // install permission's state is shared across all users. if (pkg.getTargetSdkVersion() < Build.VERSION_CODES.M - && bp.isRuntime()) { + && bp.isRuntime() && !isSpecialRuntimePermission(bp.name)) { return; } @@ -1847,7 +1848,8 @@ public class PermissionManagerService extends IPermissionManager.Stub { // If this permission was granted by default or role, make sure it is. if ((oldFlags & FLAG_PERMISSION_GRANTED_BY_DEFAULT) != 0 - || (oldFlags & FLAG_PERMISSION_GRANTED_BY_ROLE) != 0) { + || (oldFlags & FLAG_PERMISSION_GRANTED_BY_ROLE) != 0 + || isSpecialRuntimePermission(bp.getName())) { // PermissionPolicyService will handle the app op for runtime permissions later. grantRuntimePermissionInternal(permName, packageName, false, Process.SYSTEM_UID, userId, delayingPermCallback); @@ -2606,6 +2608,10 @@ public class PermissionManagerService extends IPermissionManager.Stub { } } + public static boolean isSpecialRuntimePermission(final String permission) { + return false; + } + /** * Restore the permission state for a package. * @@ -2952,6 +2958,14 @@ public class PermissionManagerService extends IPermissionManager.Stub { } } } + + if (isSpecialRuntimePermission(bp.name) && + origPermissions.getRuntimePermissionState(bp.name, userId) == null) { + if (permissionsState.grantRuntimePermission(bp, userId) + != PERMISSION_OPERATION_FAILURE) { + wasChanged = true; + } + } } else { if (permState == null) { // New permission @@ -3907,7 +3921,7 @@ public class PermissionManagerService extends IPermissionManager.Stub { && (grantedPermissions == null || ArrayUtils.contains(grantedPermissions, permission))) { final int flags = permissionsState.getPermissionFlags(permission, userId); - if (supportsRuntimePermissions) { + if (supportsRuntimePermissions || isSpecialRuntimePermission(bp.name)) { // Installer cannot change immutable permissions. if ((flags & immutableFlags) == 0) { grantRuntimePermissionInternal(permission, pkg.getPackageName(), false,
