sd_done() was calling scsi_print_sense() for a sense code
of 'NO_SENSE'.

Like scmd_printk(), but the device name is passed in as
a string. Can be used by eg ULDs which do not have access
to the scsi_cmnd structure.

This triggers lots of compiler warnings with gcc 4.4.7 like:
drivers/scsi/sd.c: In function 'sd_open':
drivers/scsi/sd.c:1179: warning: reading through null pointer (argument 4)
drivers/scsi/sd.c:1179: warning: format '%s' expects type 'char *', but argument 4 has type 'void *'
That is from:
SCSI_LOG_HLQUEUE(3, sd_printk(KERN_INFO, sdkp, "sd_open\n"));
Since:
#define NULL ((void *)0)
gcc probably doesn't realize the (p)? prevents the NULL (a void *)
from being passed to sdev_printk.
Passing "" rather than NULL eliminates the compiler warnings.
There should probably be a () around p in the sdev_printk call, too.

It eliminates the warnings, but unfortunately we then get log messages
that look like:
Oct 3 11:30:08 rhel-storage-01 kernel: sd 10:0:0:0: [sde] (null)FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
^^^^^^
Changing it to (char *)NULL, like this:
#define sd_printk(prefix, sdsk, fmt, a...) \
(sdsk)->disk ? \
sdev_prefix_printk(prefix, (sdsk)->device, \
(sdsk)->disk->disk_name, fmt, ##a) : \
sdev_prefix_printk(prefix, (sdsk)->device, \
(char *)NULL, fmt, ##a)
doesn't work either. The compiler gives an error:
drivers/scsi/sd.c: In function 'sd_open':
drivers/scsi/sd.c:1158:2: error: reading through null pointer (argument 4) [-Werror=format=]
SCSI_LOG_HLQUEUE(3, sd_printk(KERN_INFO, sdkp, "sd_open\n"));

I've fixed it up in my next iteration of the patchset.
(By simply using 'sdev_printk' if the prefix argument is NULL ...)

We should be using the standard dev_printk() variants for
sense code printing.

Update acornscsi to use scsi_print_command() instead of the
underscore version and use scmd_printk() in acornscsi_done().
This will add correct device annotations in the resulting message.
And we should be using set_host_byte() for setting the
final result.

fas216 returns DID_BAD_TARGET for an incomplete data
transfer. The midlayer uses DID_BAD_TARGET to signal
a non-existing or not reachable target. So we should
rather be using DID_ERROR here.

The 53c700 driver would be using scsi_print_sense() in a debug
statement, which was never compiled in. Plus the same information

If scsi_normalize_sense() fails we couldn't decode the sense
buffer, and the scsi_sense_hdr fields are invalid.
For those cases we should rather dump the sense buffer
and not try to decode invalid fields.

Currently we're only decoding sense extras for tape devices.
And even there only for fixed format sense formats.
As this is of rather limited use in the general case we should
be stop trying to decode sense extras; the tape driver does
its own decoding anyway.

The suggestion to rename cmd to opcode in patch 14 would
follow the movements here.

Just ARRAY_SIZE(cdb_byte0_names) is not right - that array
is always defined and the statement is always true.
Patch 16 replaces that block of code and eliminates that
issue.

Consolidate the CDB opcode lookup in scsi_opcode_sa_name(),
so that we don't have to call several functions to figure
out the CDB opcode string.

Both of those > need to be >=, since the reserved
range starts at and includes 0x60, and the vendor
specific range starts at and includes 0xc0.

print_opcode_name() was only ever called with a '0' argument
from LLDDs and ULDs which were _not_ supporting variable length
CDBs, so the 'if' clause was never triggered.

cdbp must point to a buffer containing at least 8 valid

Calling scsi_print_command should not be necessary during abort;
if the information is required one should enable scsi logging.

Open-code scsi_print_result in sd.c, and cleanup logging to
not print duplicate informations.
With that we can remove scsi_show_result in constants.c

The cdb_byte0_names[] array in constants.c capitalizes
the candidates as:
Synchronize Cache(10)
Synchronize cache(16)
Here, it's specifically the 10 byte version (so far), so
Synchronize Cache(10) failed
might be a better string. Or, if following SCSI standards,
SYNCHRONIZE CACHE(10)
without the _ would be better.
Consider changing cdb_byte0_names to Synchronize Cache(16) too.
(it has a lot of inconsistent capitalization)

Printing good_bytes here is misleading, because it is
subsequently changed from 0 to nonzero in these cases:
* HARDWARE ERROR sense key
* MEDIUM ERROR sense key
* RECOVERED ERROR sense key
* ABORTED COMMAND sense key for ASC 0x10
* ILLEGAL REQUEST sense key for ASC 0x10
* ILLEGAL REQUEST sense key for ASC/ASCQ 0x20/0x24
for WRITE SAME without the UNMAP bit
Suggestions:
1. Move the print down after the out: label, when good_bytes
has reached its final value.
2. Indicate if the command was able to transfer all the bytes
by adding:
"%d of %d bytes" good_bytes, scsi_bufflen(SCpnt)

"unit" by itself is not a real SCSI term. "Logical Unit Not
Ready" would be better, but this is printed for all non-GOOD
status values, not just CHECK CONDITION status with a sense
key of NOT READY and one of many additional sense codes with
"LOGICAL UNIT NOT READY" in their names.
Following the other prints in this patch, how about this?

The cdb_byte0_names[] array in constants.c capitalizes
the candidates as:
Read Capacity(10)
Read capacity(16)
The two callers to this function already print the opcode
name, using all caps and not printing "(10)", at the
KERN_NOTICE level:
sd_printk(KERN_NOTICE, sdkp, "READ CAPACITY(16) failed\n");
read_capacity_error(sdkp, sdp, &sshdr, sense_valid, the_result);
sd_printk(KERN_NOTICE, sdkp, "READ CAPACITY failed\n");
read_capacity_error(sdkp, sdp, &sshdr, sense_valid, the_result);
sd_print_result uses the KERN_INFO level.
To follow cdb_byte0_names, use "Read Capacity(10)" and
"Read capacity(16)" in the callers.
To follow SCSI standards, add "(10)" in the second caller.
Consider changing cdb_byte0_names to "Read Capacity(16)" too.

To follow cdb_byte0_names, use "Start/Stop Unit".
To follow SCSI standards, use "START STOP UNIT".
Since this command can request start, stop, or
various power conditions, it might be helpful to include:
start=%d pwr_cond=0x%x",
cmd[4] & 0x1,
cmd[4] >> 4 & 0xf

Since what sdkp points to is not modified, the first argument
could be:
const struct scsi_disk *sdkp

In a similar construct, patch 19 used || in scsi_print_result
to choose the string path, and printed "invalid" if one
of the strings was NULL. They should probably match.

SUCCESS is a misleading name to print on commands that were
really not successful. Example:
[ 5978.573297] sd 2:0:0:8: [sdz] tag#209 Done: SUCCESS Result: hostbyte=DID_OK driverbyte=DRIVER_OK
[ 5978.576335] sd 2:0:0:8: [sdz] tag#209 CDB: Test Unit Ready 00 00 00 00 00 00
[ 5978.578721] sd 2:0:0:8: [sdz] tag#209 Sense Key : Unit Attention [current]
[ 5978.581177] sd 2:0:0:8: [sdz] tag#209 Add. Sense: Bus device reset function occurred
Maybe that mlreturn value should be printed as
"COMPLETE" since it is similar to the SAM service
responses called COMMAND COMPLETE and FUNCTION COMPLETE.
That is a more neutral term.

I do agree that SUCCESS is rather misleading here.
However, the midlayer always used 'SUCCESS' here, and changing that
would be a different patch as it's bound to induce quite some
discussion.
I'm happy to send such a patch, but preferably _after_ this
patchset is in.
Cheers,
Hannes

I got a compile error on this, I think you need to change the above line

As noted by Ewan, the extra scmd argument causes compiler
warnings.

The EH statistics are per host, so we should be using
shost_printk() here.

scsi_try_to_abort_cmd() should only return
SUCCESS or FAILED. So document that in the
function description and simplify the
logging message.

Since the rest of that function is just:
return hostt->eh_abort_handler(scmd);
this relies on the LLD to use only those values:
#define SUCCESS 0x2002
#define FAILED 0x2003
which is hard to ensure.
Randomly picking on one, megaraid.c registers this
function:
.eh_abort_handler = megaraid_abort,
megaraid_abort returns the return code from
megaraid_abort_and_reset, which returns TRUE or FALSE,
not SUCCESS and FAILED.
Printing the return value helps expose such problems
(if the code path is exercised).

With this 24-part series applied to 3.17rc7, with the
kernel set to print timestamps (e.g., printk.time=y on the kernel
command line), the prints still end up trickling out a byte
at a time, interleaved from different threads, when the system
is overloaded.
Maybe that's addressed by the part that is deferred?

Yes, unfortunately. I just wanted to get the main bulk of
patches in now so that I can concentrate on the real issue
and don't have to carry around tons of patches.
