----------------------------------
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.
