Rasmus Villemoes e1f0bce3a0 scsi: reduce CONFIG_SCSI_CONSTANTS=y impact by 8k
On 64 bit, struct error_info has 6 bytes of padding, which amounts to
over 4k of wasted space in the additional[] array. We could easily get
rid of that by instead using separate arrays for the codes and the
pointers. However, we can do even better than that and save an
additional 6 bytes per entry: In the table, just store the sizeof()
the corresponding string literal. The cumulative sum of these is then
the appropriate offset into additional_text, which is built from the
concatenation (with '\0's inbetween) of the strings.

The Kconfig help text used to say that CONFIG_SCSI_CONSTANTS=y costs
around 75 KB, but that was a little exaggerated. The actual number was
closer to 44K, and 36K with this patch.

So we can even print out a variable length command correctly across

Douglas Gilbert 655ee63cf3 [SCSI] scsi constants: command, sense key + additional sense strings
It has been several years since the SCSI constants.c
file has been updated. The attached is against lk 3.10
and brings the command strings, sense keys and additional
sense code strings into sync with spc4r36g.pdf.

Certain SCSI command names that previously only took the
opcode (i.e. byte 0 of the cdb) into account, have been
split into several command names using the associated
service action field to differentiate. For example,
persistent reservations that previously had 2 commands
(i.e. "in" and "out") have been expanded to 12 commands
(e.g. "Persistent reserve in, read reservation").

Sync SCSI command names, sense key strings and additional
sense code strings with SPC-4 draft revision 36g

Mike Christie a4dfaa6f2e [SCSI] scsi: add transport host byte errors (v3)
Currently, if there is a transport problem the iscsi drivers will return
outstanding commands (commands being exeucted by the driver/fw/hw) with
DID_BUS_BUSY and block the session so no new commands can be queued.
Commands that are caught between the failure handling and blocking are
failed with DID_IMM_RETRY or one of the scsi ml queuecommand return values.
When the recovery_timeout fires, the iscsi drivers then fail IO with
DID_NO_CONNECT.

For fcp, some drivers will fail some outstanding IO (disk but possibly not
tape) with DID_BUS_BUSY or DID_ERROR or some other value that causes a retry
and hits the scsi_error.c failfast check, block the rport, and commands
caught in the race are failed with DID_IMM_RETRY. Other drivers, may
hold onto all IO and wait for the terminate_rport_io or dev_loss_tmo_callbk
to be called.

The following patches attempt to unify what upper layers will see drivers
like multipath can make a good guess. This relies on drivers being
hooked into their transport class.

This first patch just defines two new host byte errors so drivers can
return the same value for when a rport/session is blocked and for
when the fast_io_fail_tmo fires.

The idea is that if the LLD/class detects a problem and is going to block
a rport/session, then if the LLD wants or must return the command to scsi-ml,
then it can return it with DID_TRANSPORT_DISRUPTED. This will requeue
the IO into the same scsi queue it came from, until the fast io fail timer
fires and the class decides what to do.

When using multipath and the fast_io_fail_tmo fires then the class
can fail commands with DID_TRANSPORT_FAILFAST or drivers can use
DID_TRANSPORT_FAILFAST in their terminate_rport_io callbacks or
the equivlent in iscsi if we ever implement more advanced recovery methods.
A LLD, like lpfc, could continue to return DID_ERROR and then it will hit
the normal failfast path, so drivers do not have fully be ported to
work better. The point of the patches is that upper layers will
not see a failure that could be recovered from while the rport/session is
blocked until fast_io_fail_tmo/recovery_timeout fires.

V3
Remove some comments.
V2
Fixed patch/diff errors and renamed DID_TRANSPORT_BLOCKED to
DID_TRANSPORT_DISRUPTED.
V1

noticed that DID_REQUEUE was not in the hostbyte_table. I do not think
there is any way to hit the code path where scsi_show_result is called

always requeue the command. However, for completeness and because I want
to one day send a patch that tries to add new host bytes values, I am
sending this patch.

Martin K. Petersen 684b7fe976 [SCSI] constants.c: cleanup, verbose result printing
Clean up constants.c and make result printing more user friendly:

 - Refactor the command and sense functions so that the actual
   formatting can be called from the various helper functions with the
   correct prefix.

 - Replace scsi_print_hostbyte() and scsi_print_driverbyte() with
   scsi_print_result() which is verbose when CONFIG_SCSI_CONSTANTS is
   on.

Christoph Hellwig beb4048750 [SCSI] remove scsi_request infrastructure
With Achim patch the last user (gdth) is switched away from scsi_request
so we an kill it now.  Also disables some code in i2o_scsi that was
broken since the sg driver stopped using scsi_requests.

Matthew Wilcox 410ca5c7c6 [SCSI] Move scsi_print_msg to SPI class
scsi_print_msg() is an SPI-specific concept.  This patch moves it from
constants.c to scsi_transport_spi.c and updates the Kconfig to link in
the SPI class for the drivers which use scsi_print_msg().

patch below marks a few scsi core datastructures as const, so that they end up
in the .rodata section and don't cacheline share with things that get dirtied

James Bottomley 9ccfc756a7 [SCSI] move the mid-layer printk's over to shost/starget/sdev_printk
This should eliminate (at least in the mid layer) to make numeric
assumptions about any of the enumeration variables.  As a side effect,
it will also make all the messages consistent and line us up nicely for
the error logging strategy (if it ever shows itself again).

James Bottomley ea73a9f239 [SCSI] convert sd to scsi_execute_req (and update the scsi_execute_req API)
This one removes struct scsi_request entirely from sd.  In the process,
I noticed we have no callers of scsi_wait_req who don't immediately
normalise the sense, so I updated the API to make it take a struct
scsi_sense_hdr instead of simply a big sense buffer.
