attribute dev_type;
# All types used for processes.
attribute domain;
# Temporary attribute used for migrating permissions out of domain.
# Motivation: Domain is overly permissive. Start removing permissions
# from domain and assign them to the domain_deprecated attribute.
# Domain_deprecated and domain can initially be assigned to all
# domains. The goal is to not assign domain_deprecated to new domains
# and to start removing domain_deprecated where it's not required or
# reassigning the appropriate permissions to the inheriting domain
# when necessary.

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().
