             Summary: raw connection posts wake events after disconnect event 
is handled
                 Key: PROTON-2466
                 URL: https://issues.apache.org/jira/browse/PROTON-2466
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-c
    Affects Versions: proton-c-0.36.0
            Reporter: Ken Giusti
         Attachments: qdrouterd-A.conf

While running tcp stress tests against qdrouterd a crash occurred.  The crash 
was due to a stale pointer dereference.

qdrouterd code has been patched to properly clear the pointer and check for 
null in the effected codepath.  However...

... the access occurred while processing a PN_RAW_CONNECTION_WAKE event that 
arrived on a raw connection *after* a PN_RAW_CONNECTION_DISCONNECTED event 
previously arrived on the raw connection.

IIUC the PN_RAW_CONNECTION_DISCONNECTED event is supposed to be the last event 
generated on a raw connection, and once that event has been handled the raw 
connection is released.   If that is correct then the arrival of the following 
WAKE event is a bug.
