Align SELinux property policy with init property_perms. Introduce a net_radio_prop type for net. properties that can be set by radio or system. Introduce a system_radio_prop type for sys. properties that can be set by radio or system. Introduce a dhcp_prop type for properties that can be set by dhcp or system. Drop the rild_prop vs radio_prop distinction; this was an early experiment to see if we could separate properties settable by rild versus other radio UID processes but it did not pan out. Remove the ability to set properties from unconfineddomain. Allow init to set any property. Allow recovery to set ctl_default_prop to restart adbd.

Enable SELinux on vold This change enables SELinux security enforcement on vold. For the vold.te file ONLY, this change is conceptually a revert of 77d4731e9d30c8971e076e2469d6957619019921 and 50e37b93ac97631dcac6961285b92af5026557af, with the following additional changes: 1) Removal of "allow vold proc:file write;" and "allow vold self:capability { sys_boot };". As of system/vold change adfba3626e76c1931649634275d241b226cd1b9a, vold no longer performs it's own reboots, so these capabilities are no longer needed. 2) Addition of the powerctl property, which vold contacts to tell init to reboot. 3) Removal of "allow vold kernel:system module_request;". As of CTS commit f2cfdf5c057140d9442fcfeb4e4a648e8258b659, Android devices no longer ship with loadable modules, hence we don't require this rule. 4) Removal of "fsetid" from "self:capability". Any setuid / setgid bits SHOULD be cleared if vold is able to change the permissions of files. IMHO, it was a mistake to ever include this capability in the first place. Testing: As much as possible, I've tested filesystem related functionality, including factory reset and device encryption. I wasn't able to test fstrim functionality, which is a fairly new feature. I didn't see any policy denials in dmesg. It's quite possible I've missed something. If we experience problems, I happy to roll back this change.

Dependencies for new goldfish service domains. In order to support the new goldfish service domains in a change with the same Change-Id for the build project, we need the following changes in external/sepolicy: - /system/bin/logcat needs its own type so that it can be used as an entrypoint for the goldfish-logcat service. A neverallow rule prevents us from allowing entrypoint to any type not in exec_type. - The config. and dalvik. property namespaces need to be labeled with something other than default_prop so that the qemu-props service can set them. A neverallow rule prevents us from allowing qemu-props to set default_prop. We allow rx_file_perms to logcat_exec for any domain that was previously allowed read_logd() as many programs will read the logs by running logcat. We do not do this for all domains as it would violate a neverallow rule on the kernel domain executing any file without transitioning to another domain, and as we ultimately want to apply the same restriction to the init domain (and possibly others).

Support fine grain read access control for properties Properties are now broken up from a single /dev/__properties__ file into multiple files, one per property label. This commit provides the mechanism to control read access to each of these files and therefore sets of properties. This allows full access for all domains to each of these new property files to match the current permissions of /dev/__properties__. Future commits will restrict the access.
