[SCSI] scsi_debug: clear correct memory region when LBPRZ is enabled The function unmap_region() clears memory region specified as the logical block address and the number of logical blocks in ramdisk storage (fake_storep) if lbpu and lbprz module parameters are enabled. In the while loop of unmap_region(), it advances optimal unmap granularity in logical blocks. But it only clears one logical block at LBA 'block' per loop iteration. And furthermore, the 'block' is not pointing to a logical block address which should be cleared, it is a index of probisioning map (map_storep).

[SCSI] scsi_debug: prohibit scsi_debug_unmap_granularity == scsi_debug_unmap_alignment scsi_debug prohibits setting scsi_debug_unmap_alignment to be greater than scsi_debug_unmap_granularity. But setting them to be the same value is not prohibited. In this case, the only difference with scsi_debug_unmap_alignment == 0 is the logical blocks from 0 to scsi_debug_unmap_alignment - 1 cannot be unmapped. But the difference is not properly handled in the current code. So this prohibits such unusual setting. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Acked-by: Martin K.

[SCSI] scsi_debug: call map_region() and unmap_region() only when needed If the logical block provisioning is not enabled, map_region() and unmap_region() have no effect and they don't need to be called. So this makes map_region() and unmap_region() to be called only when scsi_debug_lbp() returns true, i.e. logical block provisioning is enabled. While I'm at it, this also removes meaningless non-zero check for scsi_debug_unmap_granularity. Because scsi_debug_unmap_granularity cannot be zero with usual setting: scsi_debug_unmap_granularity is 1 by default, and it can be changed to zero with explicit module parameter setting only when the logical block provisioning is disabled. But it is only meaningful module parameter when the logical block provisioning is enabled. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Acked-by: Martin K.

[SCSI] scsi_debug: Fix off-by-one bug when unmapping region Currently it is possible to unmap one more block than user requested to due to the off-by-one error in unmap_region(). This is probably due to the fact that the end variable despite its name actually points to the last block to unmap + 1. However in the condition it is handled as the last block of the region to unmap. The bug was not previously spotted probably due to the fact that the region was not zeroed, which has changed with commit be1dd78de5686c062bb3103f9e86d444a10ed783. With that commit we were able to corrupt the ext4 file system on 256M scsi_debug device with LBPRZ enabled using fstrim. Since the 'end' semantic is the same in several functions there this commit just fixes the condition to use the 'end' variable correctly in that context.

[SCSI] Handle disk devices which can not process medium access commands We have experienced several devices which fail in a fashion we do not currently handle gracefully in SCSI. After a failure these devices will respond to the SCSI primary command set (INQUIRY, TEST UNIT READY, etc.) but any command accessing the storage medium will time out. The following patch adds an callback that can be used by upper level drivers to inspect the results of an error handling command. This in turn has been used to implement additional checking in the SCSI disk driver. If a medium access command fails twice but TEST UNIT READY succeeds both times in the subsequent error handling we will offline the device. The maximum number of failed commands required to take a device offline can be tweaked in sysfs. Also add a new error flag to scsi_debug which allows this scenario to be easily reproduced.

[SCSI] scsi_debug: GET LBA STATUS response length correction The SCSI GET LBA STATUS command was introduced in SBC-3 revision 20 in September 2009. At that time the Parameter Data Length field in the response had an associated byte offset of 8. Then in SBC-3 revision 25 (October 2010) that byte offset was changed to 4. The sg_get_lba_status utility in sg3_utils version 1.33 (released earlier today) has been changed to calculate the newer response length. However the implementation of GET LBA STATUS command in the scsi_debug driver still uses the original byte offset. modify the Parameter Data Length field value in the GET LBA STATUS command response to comply with the change in SBC-3 revision 25 Signed-off-by: James Bottomley <JBottomley@Parallels.com>

[SCSI] scsi_debug: add consecutive medium errors A useful test case for error recovery is multiple, consecutive medium errors. When scsi_debug is started with "opts=2" a MEDIUM ERROR is generated when block 0x1234 (4660) is read. The patch extends that to 10 consecutive blocks from 0x1234 (i.e. blocks 4660 to 4669 inclusive).

Reason: time block layer takes to do useless retries and collateral damage to data in its 4 KB blocks (O_DIRECT mitigates the latter).

SCSI host lock push-down Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

[SCSI] scsi_debug: virtual_gb ignores sector_size In the scsi_debug driver, the virtual_gb option ignores the sector_size, implicitly assuming that is 512 bytes. So if 'virtual_gb=1 sector_size=4096' the result is an 8 GB (virtual) disk.
