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.

allow apps access to the keystore, dhcp/pptp fixes, wifi fixes and isolated_app access - allow all apps to connect to the keystore over unix socket - dhcp runs scripts in /system/etc/dhcpcd/dhcpcd-hooks and creates/removes lease files - mtp connects to dnsproxyd when a pptp vpn connection is established - allow appdomain to also open qtaguid_proc and release_app to read qtaguid_device - WifiWatchDog uses packet_socket when wifi comes up - apps interact with isolated_apps when an app uses an isolated service and uses sockets for that interaction - for apps with levelFromUid=true to interact with isolated_app, isolated_app must be an mlstrustedsubject Change-Id: I09ff676267ab588ad4c73f04d8f23dba863c5949 Signed-off-by: Joshua Brindle <jbrindle@tresys.com> 2012-09-25 15:52:54 -07:00			`net_domain(mtp)`

mtp: support using pppox_socket family Kernel commit da69a5306ab92e07224da54aafee8b1dccf024f6 ("selinux: support distinctions among all network address families") modified the kernel to support fine grain differentiation of socket families, if userspace enables it (which Android does). Modify the mtp SELinux policy to allow the use of pppox_socket (needed for kernels 4.14 or greater) and the generic "socket" family (for kernels below 4.14).

sepolicy: Add rules for non-init namespaces In kernel 4.7, the capability and capability2 classes were split apart from cap_userns and cap2_userns (see kernel commit 8e4ff6f228e4722cac74db716e308d1da33d744f). Since then, Android cannot be run in a container with SELinux in enforcing mode. This change applies the existing capability rules to user namespaces as well as the root namespace so that Android running in a container behaves the same on pre- and post-4.7 kernels. This is essentially: 1. New global_capability_class_set and global_capability2_class_set that match capability+cap_userns and capability2+cap2_userns, respectively. 2. s/self:capability/self:global_capability_class_set/g 3. s/self:capability2/self:global_capability2_class_set/g 4. Add cap_userns and cap2_userns to the existing capability_class_set so that it covers all capabilities. This set was used by several neverallow and dontaudit rules, and I confirmed that the new classes are still appropriate. Test: diff new policy against old and confirm that all new rules add only cap_userns or cap2_userns; Boot ARC++ on a device with the 4.12 kernel.
