* [SCSI] qla2xxx: Cover UNDERRUN case where SCSI status is set.Lalit Chandivade2010-09-051-3/+4
| | | | | | | | | Currently, if target sets the SCSI Status (with Check condition) and there is no FCP residual bit set then driver does not check for dropped frame. This could lead to data corruption. Signed-off-by: Giridhar Malavali <giridhar.malavali@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

* [SCSI] hpsa: disable doorbell reset on reset_devicesStephen M. Cameron2010-09-021-0/+6
| | | | | | | | | | | | | | | The doorbell reset initially appears to work correctly, the controller resets, comes up, some i/o can even be done, but on at least some Smart Arrays in some servers, it eventually causes a subsequent controller lockup due to some kind of PCIe error, and kdump can end up leaving the root filesystem in an unbootable state. For this reason, until the problem is fixed, or at least isolated to certain hardware enough to be avoided, the doorbell reset should not be used at all. Signed-off-by: Stephen M.

Unfortuantely, it also introduced a problem whereby for commands other than test unit ready, the eh dispatcher thinks they succeeded when reservation conflict is returned, whereas in reality they failed.

| | | | | | | | | | | | | | | | | | | | | | | | When the transport is busy and we're sending an EH command drivers occasionally return 'BUSY'. As this in most cases is the TUR command sent as part of the error recovery this is a sure way to make the error recovery escalate.

There are two possible threads now that can be deleting rports in the ibmvfc driver, which can result in list_del being called twice, resulting in an oops. This patch adds a new state to the ibmvfc_target struct to indicate the target has been removed from the list and is in the process of being deleted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Outstanding mailbox commands, have no way to recover on f/w hung, and we timeout on waiting for mbx response. This in turn affects the recovery process as follows: - We might already be in dpc while waiting for mbx to complete, so recovery for that pci function will never get invoked. Reset Timeout (10 sec) is far less than mbx timeout (30 sec). - Other mbx cmds will get stuck due to serial mbx access. Solution is to identify fw-hung scenario and handle outstanding mbx commands to have an early-exit instead of waiting for response. Other mbx commands waiting for access will also do an early-exit if fw-hung is still applicable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver is the only user of dma_is_consistent(). We plan to remove this API. The driver uses the API in the following way: BUG_ON(!dma_is_consistent(hostdata->dev, pScript) && L1_CACHE_BYTES < dma_get_cache_alignment()); The above code tries to see if L1_CACHE_BYTES is greater than dma_get_cache_alignment() on sysmtes that can not allocate coherent memory (some old systems can't). James Bottomley exmplained that this is necesary because the driver packs the set of mailboxes into a single coherent area and separates the different usages by a L1 cache stride. So it's fatal if the dma coherence stride is greater than the L1 cache size. He also pointed out that we can kill this checking because we don't hit this BUG_ON on all architectures that actually use the driver.

* | | scsi: 53c700: remove dma_is_consistent usageFUJITA Tomonori2010-08-111-3/+0

We plan to remove this API. The driver uses the API in the following way: BUG_ON(!dma_is_consistent(hostdata->dev, pScript) && L1_CACHE_BYTES < dma_get_cache_alignment()); The above code tries to see if L1_CACHE_BYTES is greater than dma_get_cache_alignment() on sysmtes that can not allocate coherent memory (some old systems can't). James Bottomley exmplained that this is necesary because the driver packs the set of mailboxes into a single coherent area and separates the different usages by a L1 cache stride. So it's fatal if the dma He also pointed out that we can kill this checking because we don't hit this BUG_ON on all architectures that actually use the driver.
