Michael Tokarev [Fri, 27 Oct 2006 12:02:37 +0000 (16:02 +0400)]
[SCSI] modalias for scsi devices

The following patch adds support for sysfs/uevent modalias
attribute for scsi devices (like disks, tapes, cdroms etc),
based on whatever current sd.c, sr.c, st.c and osst.c drivers
supports.

The modalias format is like this:

 scsi:type-0x04

(for TYPE_WORM, handled by sr.c now).

Several comments.

o This hexadecimal type value is because all TYPE_XXX constants
  in include/scsi/scsi.h are given in hex, but __stringify() will
  not convert them to decimal (so it will NOT be scsi:type-4).
  Since it does not really matter in which format it is, while
  both modalias in module and modalias attribute match each other,
  I descided to go for that 0x%02x format (and added a comment in
  include/scsi/scsi.h to keep them that way), instead of changing
  them all to decimal.

o There was no .uevent routine for SCSI bus.  It might be a good
  idea to add some more ueven environment variables in there.

o osst.c driver handles tapes too, like st.c, but only SOME tapes.
  With this setup, hotplug scripts (or whatever is used by the
  user) will try to load both st and osst modules for all SCSI
  tapes found, because both modules have scsi:type-0x01 alias).
  It is not harmful, but one extra module is no good either.
  It is possible to solve this, by exporting more info in
  modalias attribute, including vendor and device identification
  strings, so that modalias becomes something like
    scsi:type-0x12:vendor-Adaptec LTD:device-OnStream Tape Drive
  and having that, match for all 3 attributes, not only device
  type.  But oh well, vendor and device strings may be large,
  and they do contain spaces and whatnot.
  So I left them for now, awaiting for comments first.

[SCSI] sg: cap reserved_size values at max_sectors

This patch (as857) modifies the SG_GET_RESERVED_SIZE and
SG_SET_RESERVED_SIZE ioctls in the sg driver, capping the values at
the device's request_queue's max_sectors value.  This will permit
cdrecord to obtain a legal value for the maximum transfer length,
fixing Bugzilla #7026.

The patch also caps the initial reserved_size value.  There's no
reason to have a reserved buffer larger than max_sectors, since it
would be impossible to use the extra space.

The corresponding ioctls in the block layer are modified similarly,
and the initial value for the reserved_size is set as large as
possible.  This will effectively make it default to max_sectors.
Note that the actual value is meaningless anyway, since block devices
don't have a reserved buffer.

Finally, the BLKSECTGET ioctl is added to sg, so that there will be a
uniform way for users to determine the actual max_sectors value for
any raw SCSI transport.

[SCSI] aacraid: resolve compiler warnings using ptrdiff_t

Unsigned long is not always the same size as a pointer, namely on 32 bit
systems with 64 bit address space. Ptrdiff_t is the same size as a
pointer in all configurations. By using ptrdiff_t we can mitigate the
warning messages on these configurations. There should be no side
effects of this patch.

[SCSI] aacraid: Improved error handling

Received from Mark Salyzyn,

This set of fixes improve error handling stability of the driver. A popular
manifestation of the problems is an NULL pointer reference in the interrupt
handler when referencing portions of the scsi command context, or in the
scsi_done handling when an offlined device is referenced.

The aacraid driver currently does not get notification of orphaned command
completions due to devices going offline. The driver also fails to handle the
commands that are finished by the error handler, and thus can complete again
later at the hands of the adapter causing situations of completion of an
invalid scsi command context. Test Unit Ready calls abort assuming that the
abort was successful, but are not, and thus when the interrupt from the adapter
occurs, they reference invalid command contexts. We add in a TIMED_OUT flag to
inform the aacraid FIB context that the interrupt service should merely release
the driver resources and not complete the command up. We take advantage of this
with the abort handler as well for select abortable commands. And we detect and
react if a command that can not be aborted is currently still outstanding to
the controller when reissued by the retry mechanism.

[SCSI] tgt: remove the code to build sense

tgt notifies a LLD of the failure with sense when it hits the
user-space daemon bugs. However, tgt doesn't know anything about SCSI
devices that initiators talks to. So it's impossible to send proper
sense buffer (format and contents).

This patch changes tgt not to notify a LLD of the failure with bogus
sense. Instead, tgt just re-queues the failure command to the internal
list so that it will be freed cleanly later on when the scsi_host is
removed.
