initial policy for uncrypt. Add initial support for uncrypt, started via the pre-recovery service in init.rc. On an encrypted device, uncrypt reads an OTA zip file on /data, opens the underlying block device, and writes the unencrypted blocks on top of the encrypted blocks. This allows recovery, which can't normally read encrypted partitions, to reconstruct the OTA image and apply the update as normal. Add an exception to the neverallow rule for sys_rawio. This is needed to support writing to the raw block device. Add an exception to the neverallow rule for unlabeled block devices. The underlying block device for /data varies between devices within the same family (for example, "flo" vs "deb"), and the existing per-device file_context labeling isn't sufficient to cover these differences. Until I can resolve this problem, allow access to any block devices. Bug: 13083922 Change-Id: I7cd4c3493c151e682866fe4645c488b464322379 2014-02-19 22:33:32 +01:00			`# uncrypt`
Move domain_deprecated into private policy This attribute is being actively removed from policy. Since attributes are not being versioned, partners must not be able to access and use this attribute. Move it from private and verify in the logs that rild and tee are not using these permissions. Bug: 38316109 Test: build and boot Marlin Test: Verify that rild and tee are not being granted any of these permissions.

Introduce system_file_type system_file_type is a new attribute used to identify files which exist on the /system partition. It's useful for allow rules in init, which are based off of a blacklist of writable files. Additionally, it's useful for constructing neverallow rules to prevent regressions. Additionally, add commented out tests which enforce that all files on the /system partition have the system_file_type attribute. These tests will be uncommented in a future change after all the device-specific policies are cleaned up. Test: Device boots and no obvious problems.
