If an SRB is NULL but the handle is in range just drop the command instead of also resetting the adapter. If the handle is in range then the command was valid at some point and may have been aborted. Resetting the adapter can lead to extended recovery times in this case. Signed-off-by:

Aovid crashing the system in the scenario where firmware just completes the command and it can not find the command during abort mailbox processing. This scenario can lead to sp reference counter being zero. Instead of crashing the system, use WARN_ON to print warning in log file. Signed-off-by:

scsi_error: should not get sense for timeout IO in scsi error handler When an IO timeout occurs, the IO will be aborted in scsi_abort_command() and SCSI_EH_ABORT_SCHEDULED will be set. Because of that, the SCSI_EH_CANCEL_CMD will be clear in scsi_eh_scmd_add(). So when scsi error handler starts, it will get sense for this timeout IO and the scmd of the IO request will be reused. In that case, the scmd may be double released when racing with io_done(), which will result in crash. SO SCSI_EH_ABORT_SCHEDULED should also be checked when getting sense. The bug maybe reproduced when the link between host and disk is unstable. Signed-off-by:

PORT RECOVERY TIMEOUT is the maximum time between the controller's detection of the PHY down until the receipt of the ID_Frame (from the same remote SAS port). If the time expires before the ID_FRAME is received, the port is considered INVALID and can be removed. The IOP_EVENT_PORT_RECOVERY_TIMER_TMO event is reported following the IOP_EVENT_ PHY_DOWN event when the PHY/port does not recover after Port Recovery Time. Signed-off-by:

In pm8001_ccb_task_free(), the dma unmapping is done based on ccb->n_elem value. This should be initialized to zero in the task_abort(). Otherwise, pm8001_ccb_task_free() will try for dma_unmap_sg() which is invalid for task abort and can lead to kernel crash. Changes From V1: None Signed-off-by:

The driver is calling hpsa_shutdown before calling scsi_remove_host. hpsa_shutdown is disabling interrupts. scsi_remove_host can trigger I/O operations, such as SYNCHRONIZE CACHE when multipath is enabled which hang the system. Call scsi_remove_host before calling hpsa_shutdown. Reviewed-by:

A regression was introduced into the hpsa driver a while back so non-zero LUNs of multi-LUN devices may no longer be presented via a SAS based Smart Array. I have not done a bisection to discover the change that caused it. The CISS firmware specification (available on sourceforge) defines an 8 byte lunid that describes devices that the Smart Array can see/present to the system. The current code in the hpsa driver attempts to find matches for non-zero LUNs with LUN 0 for a bus/target by zeroing out byte 4 of the lunid and find a match. This method is sufficient for SCSI based Smart Arrays because byte 5 is always 0. For SAS based Smart arrays byte 5 of the lunid contains the path number for a multipath device and either one or two bits (the documentation does not define how many bits are used but it appears it may be one only) that indicate if the given path number in byte 5 must always be used to access that device. Byte 5 may not always be zero. The following are lunids (spaces added for clarity) for a MSL2024 single drive library connected via a H241 Smart Array: 00 00 00 00 01 00 00 01 (changer) 00 00 00 00 00 80 00 01 (tape) In the 4th byte (counting from 0) you can see that the tape is LUN 0 and the changer is LUN 1. The 0x80 set in the 5th byte for the tape drive means the driver should force access to path 0 (the library in this case was connected to one path only anyway). After the changes we can see the following in the dmesg output: scsi 0:3:0:0: RAID HP H241 1.18 \ PQ: 0 ANSI: 5 scsi 0:2:0:0: Sequential-Access HP Ultrium 6-SCSI 354W \ PQ: 0 ANSI: 6 scsi 0:2:0:1: Medium Changer HP MSL G3 Series 8.70 \ PQ: 0 ANSI: 5 Showing that the changer is correctly identified as LUN 1 of bus 2 target 0. Before the change the changer device is not seen. Suggested-by:

Driver crashes if the BIOS do not set up at least one memory I/O resource. This failure can happen if the device is too slow to respond during POST and is missed by the BIOS, but Linux then detects the device later in the boot process.
