Received from Mark Salyzyn, This set of fixes improve error handling stability of the driver. A popular manifestation of the problems is an NULL pointer reference in the interrupt handler when referencing portions of the scsi command context, or in the scsi_done handling when an offlined device is referenced. The aacraid driver currently does not get notification of orphaned command completions due to devices going offline. The driver also fails to handle the commands that are finished by the error handler, and thus can complete again later at the hands of the adapter causing situations of completion of an invalid scsi command context. Test Unit Ready calls abort assuming that the abort was successful, but are not, and thus when the interrupt from the adapter occurs, they reference invalid command contexts. We add in a TIMED_OUT flag to inform the aacraid FIB context that the interrupt service should merely release the driver resources and not complete the command up. We take advantage of this with the abort handler as well for select abortable commands. And we detect and react if a command that can not be aborted is currently still outstanding to the controller when reissued by the retry mechanism.
