[jira] [Created] (QPID-6784) [Java Broker, Java Client] Client sends too large frames and broker does wrong frame size validation on 0-9

Lorenz Quack created QPID-6784:
----------------------------------

             Summary: [Java Broker, Java Client] Client sends too large frames and broker does wrong frame size validation on 0-9
                 Key: QPID-6784
                 URL: https://issues.apache.org/jira/browse/QPID-6784
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker, Java Client
    Affects Versions: 0.32, 0.17
            Reporter: Lorenz Quack
            Priority: Blocker


The Client does not include the frame attributes (except for 1 byte) in its calculation of the AMQP Frame size thus creating frames which are 7 bytes too large. This happens in {{org.apache.qpid.client.BasicMessageProducer_0_8#calculateContentBodyFrameCount}} and maybe other places.
The broker on the other end does an incorrect validation (in {{AMQDecoder#decodable}} at least) where it does not take any of the attributes into account thus accepting too large frames.

Besides not being compliant with the spec this causes problems in {{NonBlockingConnectionPlainDelegate#processData}} where the frame does not fit into a single networkBuffer.

I did not investigate other protocol versions.
