Function Documentation

unsigned int LCS_testLength (  ITC_QueueID  qid  )

Deliberately damage a message length. Parameters: qid  (in) Queue/engine to corrupt LCS_testLength() will deliberately damage the message length (make it too large) the next time a protocol 3 allocation request is sent.

unsigned int LCS_testSequence (  ITC_QueueID  qid, int  tgt )

Deliberately damage a packet sequence count. Parameters: qid  (in) Queue/engine to corrupt tgt  (in) Target packet to corrupt Warning: Only protocol 3 transactions make use of the sequence number, so the corruption set up here will be only be applied to the next protocol 3 transaction seen. Protocol 2 transactions are not affected (nor do they cancel this one-shot corruption). LCS_testSequence() will deliberately damage the sequence count the next time it sees the sequence number tgt on queue/engine qid.

unsigned int LCS_testStall (  ITC_QueueID  qid, int  tgt )

Deliberately stall a transmission. Parameters: qid  (in) Queue/engine to stall tgt  (in) Target packet to stall Warning: Only protocol 3 transactions can be stalled (it makes no sense to stall the single packet of a protocol 2 transaction ... how does the receiver figure out that it didn't receive something which it never knew was coming!), so the corruption set up here will be only be applied to the next protocol 3 transaction seen. Protocol 2 transactions are not affected (nor do they cancel this one-shot corruption). LCS_testStall() will deliberately stall transmission at the target packet.

unsigned int LCS_testTransaction (  ITC_QueueID  qid, int  tgt )

Deliberately damage a packet transaction number. Parameters: qid  (in) Queue/engine to corrupt tgt  (in) Target packet to corrupt Warning: Only protocol 3 transactions make use of the transaction number, so the corruption set up here will be only be applied to the next protocol 3 transaction seen. Protocol 2 transactions are not affected (nor do they cancel this one-shot corruption). LCS_testTransaction() will deliberately damage the transaction number the next time it sees the sequence number tgt on queue/engine qid.

static unsigned int length (  void *  prm, LTX_Engine *  txe, LCBD_cl_event *  cl )  [static]

Corrupt the message length. Parameters: prm  (in) User parameter txe  (in) LTX transmit engine cl  (in) LCB command list

static unsigned int sequence (  void *  prm, LTX_Engine *  txe, LCBD_cl_event *  cl )  [static]

The mis-sequence test point plug-in. Parameters: prm  (in) User parameter txe  (in) LTX transmit engine cl  (in) LCB command list

static unsigned int stall (  void *  prm, LTX_Engine *  txe, LCBD_cl_event *  cl )  [static]

The stall test point plug-in. Parameters: prm  (in) User parameter txe  (in) LTX transmit engine cl  (in) LCB command list

static unsigned int transaction (  void *  prm, LTX_Engine *  txe, LCBD_cl_event *  cl )  [static]

The transaction number test point plug-in. Parameters: prm  (in) User parameter txe  (in) LTX transmit engine cl  (in) LCB command list
