      Address bug report denials. · 2e7a301f
      Nick Kralevich authored
      Triggering a bug report via
      Settings > Developer Options > Take bug report
      generates a number of denials.
      
      Two bugs here:
      
      1) According to the "allowed" list in
      frameworks/native/cmds/servicemanager/service_manager.c ,
      media apps, nfc, radio, and apps with system/root UIDs can register
      as a binder service. However, they were not placed into the
      binder_service domain. Fix them.
      
      2) The bugreport mechanism queries all the services and java
      programs and asks them to write to a shell owned file. Grant the
      corresponding SELinux capability.
      
      Addresses the following denials:

      Move unconfined domains out of permissive mode. · 353c72e3
      Nick Kralevich authored
      This change removes the permissive line from unconfined
      domains. Unconfined domains can do (mostly) anything, so moving
      these domains into enforcing should be a no-op.
      
      The following domains were deliberately NOT changed:
      1) kernel
      2) init
      
      In the future, this gives us the ability to tighten up the
      rules in unconfined, and have those tightened rules actually
      work.
      
      When we're ready to tighten up the rules for these domains,
      we can:
      
      1) Remove unconfined_domain and re-add the permissive line.
      2) Submit the domain in permissive but NOT unconfined.
      3) Remove the permissive line
      4) Wait a few days and submit the no-permissive change.
      
      For instance, if we were ready to do this for adb, we'd identify
      a list of possible rules which allow adbd to work, re-add
      the permissive line, and then upload those changes to AOSP.
      After sufficient testing, we'd then move adb to enforcing.
      We'd repeat this for each domain until everything is enforcing
      and out of unconfined.

      Make all domains unconfined. · 77d4731e
      repo sync authored
      This prevents denials from being generated by the base policy.
      Over time, these rules will be incrementally tightened to improve
      security.
