commit ac791f19a273a7fe254a7596f193af6534582a9f upstream. If the tx_ignore_nack_until_eom error injection was activated, then tx_nacked was never set instead of setting it when the last byte of the message was transmitted. As a result the transmit was marked as OK, when it should have been NACKed. Modify the condition so that it always sets tx_nacked when the last byte of the message was transmitted.
