             Summary: Authenticated message size is restricted to 65535 bytes
                 Key: QPID-7105
                 URL: https://issues.apache.org/jira/browse/QPID-7105
             Project: Qpid
          Issue Type: Bug
          Components: C++ Broker
         Environment: RH Linux
            Reporter: Alexander Moibenko


Hello,
 I recently found that authenticated message size (GSSAPI in my case) is
restricted to 65535.
 In cyrus-sasl there also is a restriction. According to gssapi.c it is
 0xFFFFFF=16777215.
 In qpid SaslFactory.cpp it is hard-coded to secprops.maxbufsize = 65535;
 There are also some places where maxFrameSize is set to
 65535. What does this mean? I know that there is a restriction on UDP
 message size, which is 64KB, but why there is a restriction to
authenticated TCP/IP qpid message? There is not restriction to 
non-authenticated message though.
Gordon Sim confirmed this as a bug and recommended to JIRA.
Alexander.
P.S. I did not indicate version, because this is in allversions
