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.

Move net.dns* to it's own label. Move net.dns* from net_radio_prop to the newly created label net_dns_prop. This allows finer grain control over this specific property. Prior to this change, this property was readable to all SELinux domains, and writable by the following SELinux domains: * system_server * system_app (apps which run as UID=system) * netmgrd * radio This change: 1) Removes read access to this property to everyone EXCEPT untrusted_app and system_server. 2) Limit write access to system_server. In particular, this change removes read access to priv_apps. Any priv_app which ships with the system should not be reading this property.

ro.runtime. u:object_r:system_prop:s0
Remove access to ro.runtime.firstboot from apps ro.runtime.firstboot system property is only used internally by system_server to distinguish between first start after boot from consecutive starts (for example, this happens when full-disk encryption is enabled). The value of the property is a millisecond-precise timestamp which can help track individual device. Thus apps should not have access to this property. Test: Device boots fine, reading ro.runtime.firstboot from an app results in an error and SELinux denial. Bug: 33700679 Change-Id: I4c3c26a35c5dd840bced3a3e53d071f45317f63c

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.

Increase communication surface between dumpstate and Shell: - Add a new 'dumpstate' context for system properties. This context will be used to share state between dumpstate and Shell. For example, as dumpstate progresses, it will update a system property, which Shell will use to display the progress in the UI as a system notification. The user could also rename the bugreport file, in which case Shell would use another system property to communicate such change to dumpstate. - Allow Shell to call 'ctl.bugreport stop' so the same system notification can be used to stop dumpstate.

limit shell's access to log.* properties Restrict the ability of the shell to set the log.* properties. Namely: only allow the shell to set such properities on eng and userdebug builds. The shell (and other domains) can continue to read log.* properties on all builds. While there: harmonize permissions for log.* and persist.log.tag. Doing so introduces two changes: - log.* is now writable from from |system_app|. This mirrors the behavior of persist.log.tag, which is writable to support "Developer options" -> "Logger buffer sizes" -> "Off". (Since this option is visible on user builds, the permission is enabled for all builds.) - persist.log.tag can now be set from |shell| on userdebug_or_eng().

SELinux rule for ro.device_owner and persist.logd.security They are introduced for the device owner process logging feature. That is, for enterprise-owned devices with device owner app provisioned, the device owner may choose to turn on additional device-wide logging for auditing and intrusion detection purposes. Logging includes histories of app process startup, commands issued over ADB and lockscreen unlocking attempts. These logs will available to the device owner for analysis, potentially shipped to a remote server if it chooses to. ro.device_owner will be a master switch to turn off logging, if the device has no device owner provisioned. persist.logd.security is a switch that device owner can toggle (via DevicePoliyManager) to enable/disable logging.

Assign a label to the ro.boottime.* properties system/core commit 331cf2fb7c16b5b25064f8d2f00284105a9b413f created a number of new properties of the form: [ro.boottime.init]: [5294587604] [ro.boottime.InputEventFind]: [10278767840] [ro.boottime.adbd]: [8359267180] ... These properties were assigned the default_prop SELinux label because a better label did not exist. Properties labeled with the default_prop label are readable to any SELinux domain, which is overly broad. bullhead:/ $ getprop -Z ro.boottime.adbd u:object_r:default_prop:s0 Instead, create a new label for the ro.boottime.* properties so we can apply more fine grain read access control to these properties. bullhead:/ $ getprop -Z ro.boottime.adbd u:object_r:boottime_prop:s0 New SELinux property labels have minimal permissions by default. As a result, after this change, ro.boottime.* properties will only be readable to system_server, bootstat, init (because it manages the property space), and "adb root" (because no SELinux permissions are enforced there). Additional read access can be granted as-needed. This is part of a larger effort to implement fine-grain access control on the properties managed by init.

Restrict access to ro.serialno and ro.boot.serialno This restricts access to ro.serialno and ro.boot.serialno, the two system properties which contain the device's serial number, to a select few SELinux domains which need the access. In particular, this removes access to these properties from Android apps. Apps can access the serial number via the public android.os.Build API. System properties are not public API for apps. The reason for the restriction is that serial number is a globally unique identifier which cannot be reset by the user. Thus, it can be used as a super-cookie by apps. Apps need to wean themselves off of identifiers not resettable by the user.

persist.sys.boot.reason is cleared once read by bootstat To ensure a surprise reboot does not take the last boot reason on face value especially if coming from more than one boot sessions ago. We shift and clear the value from persist.sys.boot.reason to sys.boot.reason.last and establish a correct last reboot reason in the canonical sys.boot.reason property. As a result, the power manager should read the canonical sys.boot.reason for a definitive result rather than relying on the possibly incorrect values in the persistent storage. sys.boot.reason should be a core property as it represents the canonical boot reason API.

SELinux rule for ro.device_owner and persist.logd.security They are introduced for the device owner process logging feature. That is, for enterprise-owned devices with device owner app provisioned, the device owner may choose to turn on additional device-wide logging for auditing and intrusion detection purposes. Logging includes histories of app process startup, commands issued over ADB and lockscreen unlocking attempts. These logs will available to the device owner for analysis, potentially shipped to a remote server if it chooses to. ro.device_owner will be a master switch to turn off logging, if the device has no device owner provisioned. persist.logd.security is a switch that device owner can toggle (via DevicePoliyManager) to enable/disable logging. Writing to both properties should be only allowed by the system server. Bug: 22860162 Change-Id: Iabfe2347b094914813b9d6e0c808877c25ccd038

Finer grained permissions for ctl. properties Currently, permissions for ctl. property apply to each action verb, so if a domain has permissions for controlling service 'foo', then it can start, stop, and restart foo. This change implements finer grainer permissions such that permission can be given to strictly start a given service, but not stop or restart it. This new permission scheme is mandatory for the new control functions, sigstop_on, sigstop_off, interface_start, interface_stop, interface_restart.

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).

Combine vendor-init-actionable with vendor-init-readable Historically, vendor-init-actionable was created since the various property_contexts files were not yet available when init parses its scripts. Since then, the property_contexts files are now always available when init parses its scripts, so we can collapse these two categories. Specifically, this change ensures that all of the properties in the previous 'stable_properties.h' file in init, which contained the vendor-init-actionable properties, are able to be read by init according to SEPolicy.

Use a property instead of file to communicate cold boot done Ueventd can't set properties currently, but this is an artificial limitation, since ueventd communicates to init that it has finished cold boot via a file, and init polls this file instead of returning to the epoll loop, where properties are handled. A related change replaces that file with a property and thus frees ueventd to be able to set properties. This change creates the cold_boot_done property type for this property and gives only ueventd permissions to set it. Bug: 62301678 Test: boot, check that properties are set Change-Id: I40843b423b192ea841db6a82f648e5bab9738e0e
