Hylke van der Schaaf 2f4f7135fb Validate fixed header bits in MQTT (#11389) ... Motivation: The MQTT spec states that the bits in the fixed header must be set to specific values depending on message type. If a client sends a message with the wrong bits, the server must treat the message as malformed. Netty did not check the value of the reserved bits in the fixed header. See: MQTT3.1.1: http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/errata01/os/mqtt-v3.1.1-errata01-os-complete.html#_Toc442180835 MQTT 5.0: https://docs.oasis-open.org/mqtt/mqtt/v5.0/os/mqtt-v5.0-os.html#_Toc3901023 Modification: Add validation checks to MqttDecoder.java Add unit tests to MqttCodecTest.java Fixed two instances where messages were generated for other unit tests with an incorrect fixed header. Result: Fixes #11379.		2021-06-16 14:59:15 +02:00
