[SCSI] sd,sr: add early detection of medium not present

2008-01-12T00:22:50+00:00

The current scsi_test_unit_ready() is updated to return sense code
information (in struct scsi_sense_hdr).  The sd and sr drivers are
changed to interpret the sense code return asc 0x3a as no media and
adjust the device status accordingly.

[PATCH] scsi: kill overeager "not-ready" messages

2006-07-28T07:04:09+00:00

HAL and friends have a tendency to trigger this one all the time.
It's not really interesting, so kill it. The vendor kernels all do
anyways.

[SCSI] remove scsi_request infrastructure

2006-06-10T21:24:40+00:00

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.

[SCSI] unify SCSI_IOCTL_SEND_COMMAND implementations

2006-04-13T15:13:15+00:00

We currently have two implementations of this obsolete ioctl, one in
the block layer and one in the scsi code.  Both of them have drawbacks.

This patch kills the scsi layer version after updating the block version
with the missing bits:

 - argument checking
 - use scatterlist I/O
 - set number of retries based on the submitted command

This is the last user of non-S/G I/O except for the gdth driver, so
getting this in ASAP and through the scsi tree would be nie to kill
the non-S/G I/O path.  Jens, what do you think about adding a check
for non-S/G I/O in the midlayer?

Thanks to  Or Gerlitz for testing this patch.

This patch attempts to fix an issue found in drivers/scsi/scsi_ioctl.c by Coverity.

Error reported:

File: /export2/p4-coverity/mc2/linux26/drivers/scsi/scsi_ioctl.c
Function: scsi_ioctl_send_command
Description: Variable "buf" tracked as NULL was passed to a function that dereferences it.

Patch description:
buf can be NULL if inlen and outlen are both 0. This patch adds check if the
length is non-zero before calling copy from/to user.

[SCSI] move the mid-layer printk's over to shost/starget/sdev_printk

2005-10-28T19:23:02+00:00

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).

[SCSI] fix oops on usb storage device disconnect

2005-09-19T14:24:52+00:00

We fix the oops by enforcing the host state model.  There have also
been two extra states added: SHOST_CANCEL_RECOVERY and
SHOST_DEL_RECOVERY so we can take the model through host removal while
the recovery thread is active.
