Strings: UTF-8 with no embedded NULs, by adding a new internal function, _dbus_check_is_valid_utf8 Object paths, signatures: the obvious syntactic checks This moves some of the burden of validation to the sender. When sending <http://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-demo.txt> 10240 times with up to 1024 parallel calls pending, on a single-core ARM Linux device, I found that user CPU time in dbus-spam increased by up to 80% as a result of the validation. However, when sending messages to dbus-daemon, overall throughput only reduced by 15%, and when sending messages to an echo service, overall throughput actually improved by around 14% (presumably because making the sender CPU-bound influenced kernel scheduling).
