This patch ensures that the modern adapters get a maximum sg segment size on par with the maximum transfer size. Added some localized janitor fixes to the discussion patch I used with Fujita.

When sending a SCSI command to a tape drive via the SCSI Generic (sg) driver, if the command has a data transfer length more than scatter_elem_sz (32 KB default) and not a multiple of 512, then I either hit BUG_ON(!valid_dma_direction(direction)) in dma_unmap_sg() or else the command never completes (depending on the LLDD). When constructing scatterlists, the sg driver rounds up the scatterlist element sizes to be a multiple of 512. This can result in sum(scatterlist lengths) > bufflen. In this case, scsi_req_map_sg() incorrectly sets bio->bi_size to sum(scatterlist lengths) rather than to bufflen. When the command completes, req_bio_endio() detects that bio->bi_size != 0, and so it doesn't call bio_endio(). This causes the command to be resubmitted, resulting in BUG_ON or the command never completing. This patch makes scsi_req_map_sg() set bio->bi_size to bufflen rather than to sum(scatterlist lengths), which fixes the problem. Signed-off-by:

- add arcmsr_enable_eoi_mode()and readl(reg->iop2drv_doorbell_reg) in arcmsr_handle_hbb_isr() on adapter Type B in case of the doorbell interrupt clearance is cached - add conditional declaration for arcmsr_pci_error_detected() and arcmsr_pci_slot_reset - check if the sg list member number exceeds arcmsr default limit in arcmsr_build_ccb() - change the returned value type of arcmsr_build_ccb()from "void" to "int" returns FAILED in arcmsr_queue_command() - modify arcmsr_drain_donequeue() to ignore unknown command and let kernel process command timeout. This could handle IO request violating maximum segments, i.e. Linux XFS over DM-CRYPT. Thanks to Milan Broz's comments <mbroz@redhat.com> - fix the release of dma memory for type B in arcmsr_free_ccb_pool() - fix the arcmsr_polling_hbb_ccbdone() Signed-off-by:

Some devices report medium error locations incorrectly. Add guards to make sure the reported bad lba is actually in the request that caused it. Additionally remove the large case statment for sector sizes and replace it with the proper u64 divisions. Tested-by:

[SCSI] qla2xxx: Correct issue where incorrect init-fw mailbox command was used on non-NPIV capable ISPs. BIT_2 of the firmware attributes is only valid on FW-interface-2 type HBAs. Code in commit c48339de would cause the incorrect initialize-firmware mailbox command to be issued for non-NPIV capable ISPs. Correct this by reverting to previously used (and correct) pre-condition 'if' check. Signed-off-by:

For following fc_host specific attributes, vports rely on the pport. So, this patch changed way to access the data for those attributes so that they can access pport's. - get_host_speed (speed) - get_host_port_state (port_state) - get_host_port_type (port_type) - get_fc_host_stats Also, added PORT_SPEED_8GB case in the speed attribute for 8Gb HBAs.

There's no functional change involved with this update, instead it simply migrates the "set cleared interrupt state" codes to a more approprate method, qla2x00_request_irqs(), and cleans-up the driver's probe() logic. Signed-off-by:

Hmm, it looks like the conversion to resource_size_t usage (3776541d) requires some additional fixups to cleanup the structure-pointer castings used during IO mapped accesses to the chip. There's only a small number of locations, where the driver uses IO mapped accesses to the hardware, the patch below should take care of it without introducing to many structural changes to code flow.

The session age mask is only 4 bits, but session->age is 32. When it gets larger then 15 and we try to or the bits some bits get dropped and the check for session age in iscsi_verify_itt is useless. The ISCSI_CID_MASK related bits are also useless since cid is always one. Signed-off-by:

Some iscsi class messages have the dev_printk prefix and some libiscsi and iscsi_tcp messages have "iscsi" or the module name as a prefix which is normally pretty useless when trying to figure out which session or connection the message is attached to. This patch adds iscsi lib and class dev_printks so all messages have a common prefix that can be used to figure out which object printed it. Signed-off-by:

qla4xxx has the old school startup/probe where it finds presetup sessions in its flash and then attempts to log into them before returning from the probe. This however, makes it very simple to add a iscsi class scan finished helper which the driver can use. In future patches Dave or I will rip apart the driver to make it more like qla2xxx, but for now this is a very simple two line patch which fixes the problem of trying to figure out when the initial sessions are done being scanned.

In qla4xxx's probe it will call the iscsi session setup functions for session that got setup on the initial start. This then makes it easy for the iscsi class to export a helper which indicates when those scans are done. Signed-off-by:

If qla4xxx is resetting up a session and the recovery timer fires we do not want to just set it to dead, because the dpc thread could have just set it to online and is in the middle of resetting it up. Signed-off-by:

This just adds iscsi session scanning which works like fc rport scanning. The future patches will hook the drivers into Mathew Wilcox's async scanning infrastructure, so userspace does not have to special case iscsi and so userspace does not have to make a extra special case for hardware iscsi root scanning.

This has qla4xxx use the iscsi class's check ready function in the queue command function, so all iscsi drivers return the same error value for common problems. Signed-off-by:

Mike Christie authored
Qla4xxx can just call the iscsi recovery functions directly. There is no need for userspace to do this for qla4xxx, because we do not use the mutex to iterate over devices anymore and iscsi_block /unblock_session can be called from interrupt context or the dpc thread. And having userspace do this just creates uneeded headaches for qla4xxx root situations where the session may experience problems. For example during the kernel shutdown the scsi layer wants to send sync caches, but at this time userspace is not up (iscsid is not running), so we cannot recover from the problem. Signed-off-by:

It should be desired that 64 KiB is available for ATAPI transferrring. (Historically) in SCSI/block layer sector size is defined as 512 during sector-byte calculation. Originally in ps3rom.c CD_FRAMESIZE (2048) was used, which limited /sys/block/sr0/queue/max_sectors_kb to 16 KiB (32 sectors). Signed-off-by:
