[SCSI] Add detailed SCSI I/O errors

2011-02-12T16:33:08Z

Instead of just passing 'EIO' for any I/O error we should be notifying the upper layers with more details about the cause of this error. Update the possible I/O errors to: - ENOLINK: Link failure between host and target - EIO: Retryable I/O error - EREMOTEIO: Non-retryable I/O error - EBADE: I/O error restricted to the I_T_L nexus 'Retryable' in this context means that an I/O error _might_ be restricted to the I_T_L nexus (vulgo: path), so retrying on another nexus / path might succeed. 'Non-retryable' in general refers to a target failure, so this error will always be generated regardless of the I_T_L nexus it was send on. I/O errors restricted to the I_T_L nexus might be retried on another nexus / path, but they should _not_ be queued if no paths are available.

[SCSI] fix incorrect value of SCSI_MAX_SG_CHAIN_SEGMENTS due to include file ordering

2011-01-24T17:49:34Z

If the compiled object doesn't include linux/scatterlist.h before scsi/scsi.h, it will get an incorrect definition of SCSI_MAX_SG_CHAIN_SEGMENTS. Signed-off-by: David Dillow Cc: stable@kernel.org Signed-off-by: James Bottomley

[SCSI] Add missing SPC-4 CDB and MAINTENANCE_[IN,OUT] service action definitions

2010-12-21T18:37:30Z

This patch adds a handful of missing CDBs defs that are used by TCM persistent reservation logic in the SPC-4 defined CDB exclusion table for registrations and reservations. This includes a number of missing MI_* and MO_* prefixed service actions defs for MAINTENANCE_IN and MAINTENANCE_OUT that are mentioned wrt to persistent registration and reservation status for the SCSI Initiator Port.

sr: implement sr_check_events()

2010-12-16T16:53:39Z

Replace sr_media_change() with sr_check_events(). It normally only uses GET_EVENT_STATUS_NOTIFICATION to check both media change and eject request. If @clearing includes DISK_EVENT_MEDIA_CHANGE, it issues TUR and compares whether media presence has changed. The SCSI specific media change uevent is kept for compatibility. sr_media_change() was doing both media change check and revalidation. The revalidation part is split into sr_block_revalidate_disk().

USB: gadget: storage: reuse definitions from scsi.h header file

2010-10-22T17:22:07Z

This commit changes storage_common.h, file_storage.c and f_mass_storage.c to use definitions of SCSI commands from scsi/scsi.h file instead of redefining the commands in storage_common.c. scsi/scsi.h header file was missing READ_FORMAT_CAPACITIES and READ_HEADER so this commit also add those to the header.

block/scsi: Provide a limit on the number of integrity segments

2010-09-10T18:50:10Z

Some controllers have a hardware limit on the number of protection information scatter-gather list segments they can handle. Introduce a max_integrity_segments limit in the block layer and provide a new scsi_host_template setting that allows HBA drivers to provide a value suitable for the hardware. Add support for honoring the integrity segment limit when merging both bios and requests. Signed-off-by: Martin K. Petersen Signed-off-by: Jens Axboe

scsi: use __uX types for headers exported to user space

2010-08-11T15:59:01Z

Commit 9e4f5e29 ("FC Pass Thru support") exported a number of header files in include/scsi to user space, but didn't change the uX types to the userspace-compatible __uX types.
