Opened: Sep 30, 2014
Severity: 4-Minor

Symptoms

The SPDY filter incorrectly handles the error case in which a child flow is aborted.

Impact

Potential disruption of valid client traffic, in theory.

Conditions

A child flow that is aborted for any reason would trigger an superfluous ABORT event to be sent by SPDY.

Workaround

None.

Fix Information

SPDY no longer sends superfluous aborts to an already aborting child flow.
