Since the way we allocate commands with a separate sense buffer is getting complicated, we should isolate setup and teardown to a single routine so that if it gets even more complex, there's only one place in the code that needs to be altered. Signed-off-by: -

Note that if scsi_bufflen(cmd) is not zero, the command always has an sg list. So this patch doesn't do the error checking in fill_from_dev_buffer and fetch_to_dev_buffer did. Signed-off-by:

LLDs need to copies data between the SG table in struct scsi_cmnd and liner buffer. So they use the helper functions like sg_copy_from_buffer(scsi_sglist(sc), scsi_sg_count(sc), buf, buflen) sg_copy_to_buffer(scsi_sglist(sc), scsi_sg_count(sc), buf, buflen) This patch just adds wrapper functions: scsi_sg_copy_from_buffer(sc, buf, buflen) scsi_sg_copy_to_buffer(sc, buf, buflen) Signed-off-by:

This patch adds new three helper functions to copy data between an SG list and a linear buffer. - sg_copy_from_buffer copies data from linear buffer to an SG list - sg_copy_to_buffer copies data from an SG list to a linear buffer When the APIs copy data from a linear buffer to an SG list, flush_kernel_dcache_page is called. It's not necessary for everyone but it's a no-op on most architectures and in general the API is not used in performance critical path. Signed-off-by:

We've verified that there are 64 bit and endianness problems in the flashpoint driver. Reverse the logic of CONFIG_OMIT_FLASHPOINT (make it CONFIG_SCSI_FLASHPOINT) and make it depend on X86_32 so it can't appear for any other architectures. Long term, if someone chooses, they could make FlashPoint 64 bit compliant (it looks like its a question of fixing up the sizes in some of the packed descriptors) Signed-off-by: -

When a FSF physical close returns the status boxed, this means that another system already closed the port. For our system this is the same status as in the good path, we have to send the normal close. So, set the status for the boxed response to the same as for the good status. Signed-off-by:

[based on proposal from Mike Christie <michaelc@cs.wisc.edu>, this patch adds some simplifications to the handler functions] With the new target reset handler callback in the SCSI midlayer, the device reset handler in zfcp can be split in two parts. Now, zfcp does not have to track anymore whether the device supports LUN resets, so remove this flag and let the SCSI midlayer decide what to do. The device reset handler simply issues a LUN reset and the target reset handler a target reset. Signed-off-by:

The problem is that serveral drivers are sending a target reset from the device reset handler, and if we have multiple devices a target reset gets sent for each device when only one would be sufficient. And if we do a target reset it affects all the commands on the target so the device reset handler code only cleaning up one devices's commands makes programming the driver a little more difficult than it should be. This patch adds a target reset handler, which drivers can use to send a target reset. If successful it cleans up the commands for a devices accessed through that starget. Signed-off-by:

As we no longer need to calculate the data length of the whole scatterlist, we can abort the loop earlier and coalesce req_len and act_len into one variable, making fill_from_dev_buffer() more similar to fetch_to_dev_buffer(). Signed-off-by:

When aacraid spoofs READ_CAPACITY_16, it assumes that the data length in the sg list is equal to allocation length in cdb. But sg can put any value in scb so the driver needs to check both the data length in the sg list and allocation length in cdb. If allocation length is larger than the response length that the driver expects, it clears the data buffer in the sg list to zero but it doesn't need to do. Just setting resid is fine. Signed-off-by:

Show the current binary tape driver and mode options is sysfs. A file (options) is created in each directory in /sys/class/scsi_tape. The files contain masks showing the options. The mask bit definitions are the same as used when setting the options using the MTSETDRVBUFFER function in the MTIOCTOP ioctl (defined in include/linux/mtio.h). For example: > cat /sys/class/scsi_tape/nst0/options 0x00000d07 [jejb: updated doc with correction from Randy Dunlap] Signed-off-by:

Add new option MT_ST_SILI to enable setting the SILI bit in reads in variable block mode. If SILI is set, reading a block shorter than the byte count does not result in CHECK CONDITION. The length of the block is determined using the residual count from the HBA. Avoiding the REQUEST SENSE command for every block speeds up some real applications considerably. Signed-off-by:

I overlooked ips_scmd_buf_write and ips_scmd_buf_read when I converted ips to use the data buffer accessors. ips is unlikely to use sg chaining (especially in this path) since a) this path is used only for non I/O commands (with little data transfer), b) ips's sg_tablesize is set to just 17. Thanks to Tim Pepper for testing this patch. Signed-off-by:
