TMM might crash if CONNFLOW_FLAG_L7_POLICY is not set in the connection flow flags, but the system still tries to call Centralized Policy Matching (CPM).


TMM/(CPM Module) might crash.


This occurs when TCLRULE_HTTP_RESPONSE is triggered from the server-side, if the server-side does not process the policy, and the connection flow flags do not have CONNFLOW_FLAG_L7_POLICY set.



Fix Information

The system now adds the flag check of CONNFLOW_FLAG_L7_POLICY if it is not already set, so there is no crash in TMM or Centralized Policy Matching (CPM).
