      Allow ueventd to set verity.* properties · 47cd53a5
      Sami Tolvanen authored
      On dm-verity errors, we catch uevents in ueventd and set the value
      for a matching verity.* property. Allow ueventd to actually change
      property values.

      Dependencies for new goldfish service domains. · 54e9bc45
      Stephen Smalley authored
      
      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).

      Align SELinux property policy with init property_perms. · fee49159
      Stephen Smalley authored
      
      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.

      debuggerd: Allow "debug.db.uid" usage · 77aa370c
      Nick Kralevich authored
      Allow the use of debug.db.uid on userdebug / eng builds.
      Setting this property allows debuggerd to suspend a process
      if it detects a crash.
      
      Make debug.db.uid only accessible to the su domain. This should
      not be used on a user build.
      
      Only support reading user input on userdebug / eng builds.
      
      Steps to reproduce with the "crasher" program:
      
        adb root
        adb shell setprop debug.db.uid 20000
        mmm system/core/debuggerd
        adb sync
        adb shell crasher

      Enable SELinux on vold · 7914a47f
      Nick Kralevich authored
      This change enables SELinux security enforcement on vold.
      
      For the vold.te file ONLY, this change is conceptually a revert of
      77d4731e and
      50e37b93, 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.
