Ken Giusti updated PROTON-2466:
-------------------------------
Attachment: qdrouterd-B.conf
> 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
> Priority: Major
> Attachments: qdrouterd-A.conf, qdrouterd-B.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.
