- Largish commit, buffer and access controls done together - Add LOG_ID_SECURITY binary content log - Add "default" meta buffer - allow LOG_ID_SECURITY only from AID_SYSTEM and AID_ROOT UID & GID - Use __android_log_security() to gate logging - Add __android_log_security_bwrite() native access to security logging. - Add liblog.__security_buffer end-to-end gTest Bug: 26029733 Change-Id: Ibcf5b4660c17c1aa6902c0d93f8ffd29c93d9a93
