* hpsa: correct initialization order issueDon Brace2016-04-29
| | | | | | | | | | | | | | | | | The driver was calling scsi_scan_host before enabling interrupts. This has gone unnoticed except for customers running in intx mode. Calling scsi_scan_host before interrupts are enabled causes "irq XX: nobody cared" messages and the driver to hang. This patch enables interrupts before the call to scsi_scan_host.

* aacraid: Fix for KDUMP driver hangRaghava Aditya Renukunta2016-04-29
| | | | | | | | | | | | | | | | | When KDUMP is triggered the driver first talks to the firmware in INTX mode, but the adapter firmware is still in MSIX mode. Therefore the first driver command hangs since the driver is waiting for an INTX response and firmware gives a MSIX response. If when the OS is installed on a RAID drive created by the adapter KDUMP will hang since the driver does not receive a response in sync mode. Fixed by: Change the firmware to INTX mode if it is in MSIX mode before sending the first sync command.

* aacraid: Fix for aac_command_thread hangRaghava Aditya Renukunta2016-04-29
| | | | | | | | | | | | | | | | | | | | | | | Typically under error conditions, it is possible for aac_command_thread() to miss the wakeup from kthread_stop() and go back to sleep, causing it to hang aac_shutdown. In the observed scenario, the adapter is not functioning correctly and so aac_fib_send() never completes (or time-outs depending on how it was called). Shortly after aac_command_thread() starts it performs aac_fib_send(SendHostTime) which hangs. When aac_probe_one /aac_get_adapter_info send time outs, kthread_stop is called which breaks the command thread out of it's hang. The code will still go back to sleep in schedule_timeout() without checking kthread_should_stop() so it causes aac_probe_one to hang until the schedule_timeout() which is 30 minutes.

* aacraid: Relinquish CPU during timeout waitRaghava Aditya Renukunta2016-04-29
| | | | | | | | | | | | | | | | | | aac_fib_send has a special function case for initial commands during driver initialization using wait < 0(pseudo sync mode). In this case, the command does not sleep but rather spins checking for timeout.This loop is calls cpu_relax() in an attempt to allow other processes/threads to use the CPU, but this function does not relinquish the CPU and so the command will hog the processor. This was observed in a KDUMP "crashkernel" and that prevented the "command thread" (which is responsible for completing the command from being timed out) from starting because it could not get the CPU.

| | | | | | | | | | | | | | | | | | | | | | | | In OCR path, before calling chip reset calls function megasas_wait_for_outstanding_fusion to check reason for OCR. In case of firmware FAULT initiated OCR and DCMD timeout initiated timeout, driver will clear any outstanding reply (yet to be processed by driver) in reply queues before going for chip reset. This code is added to handle a scenario when IO timeout initiated adapter reset and management application initiated adapter reset (by sending command to FAULT firmware) happens simultaneously since adapter reset function is safe-guarded by reset_mutex so only thread will be doing controller reset. Consider IO timeout thread gets mutex and proceeds with adapter reset process after disabling interrupts and by the time management application has fired command to firmware to do adapter reset and the same command is completed by firmware but since interrupts are disabled, driver will not get completion and the same command will be in outstanding/pending commands list of driver and refires same command from IO timeout thread after chip reset which will again FAULT firmware and eventually causes kill adapter.

When we are in connection recovery and the internal command timer on a request pops, either the scsi_cmnd->device or scsi_cmnd->device->host back pointers may be NULL as the device that the command that the request was submitted on may have been subsequently reaped due to the connection recovery. This can cause one or both of the pointers above to be NULL and cause a system crash if we try to return the command to the midlayer. Instead, double check the pointers before the return to the midlayer so as to prevent the crash and let the upper layers finish the session recovery and rediscover the device.
