[SCSI] libosd: OSD2r05: on-the-wire changes for latest OSD2 revision 5.

2009-04-27T16:05:49+00:00

OSC's OSD2 target: [git clone git://git.open-osd.org/osc-osd/ master]
(Initiator code prior to this patch must use: "git checkout CDB_VER_OSD2r01"
 in the target tree above)

This is a summery of the wire changes:

 * OSDv2_ADDITIONAL_CDB_LENGTH == 192 => 228 (Total CDB is now 236 bytes)
 * Attributes List Element Header grew, so attribute values are 8 bytes
   aligned.
 * Cryptographic keys and signatures are 20 => 32
 * Few new definitions.

(Still missing new standard definitions attribute values, these do not change
 wire format and will be added later when needed)

[SCSI] libosd: OSD2r05: OSD_CRYPTO_KEYID_SIZE will grow 20 => 32 bytes

2009-04-27T16:05:41+00:00

In OSD2r04 draft, cryptographic key size changed to 32 bytes from
OSD1's 20 bytes. This causes a couple of on-the-wire structures
to change, including the CDB.

In this patch the OSD1/OSD2 handling is separated out in regard
to affected structures, but on-the-wire is still the same. All
on the wire changes will be submitted in one patch for bisect-ability.

[SCSI] libosd: OSD2r05: Prepare for rev5 attribute list changes

2009-04-27T16:05:40+00:00

In OSD2r05 draft each attribute list element header was changed
so attribute-value would be 8 bytes aligned. In OSD2r01-r04
it was aligned on 2 bytes. (This is because in OSD2r01 the complete
element was 8 bytes padded at end but the header was not adjusted
and caused permanent miss-alignment.)

OSD1 elements are not padded and might be or might not be aligned.
OSD1 is still supported.

In this code we do all the code re-factoring to separate OSD1/OSD2
differences but do not change actual wire format. All wire format
changes will happen in one patch later, for bisect-ability.

[SCSI] mpt2sas: fix hotplug event processing

2009-04-27T15:54:15+00:00

Here's a fix for hotplug events.  The useage of queue_delayed_work seems
to broke the fifo for processing of firmware events.  After several iterations
of adding and removing cabling connected to jbods, the devices are not
getting added becuase kernel thread is activited out of order.

[SCSI] mpt2sas : release diagnotic buffers prior host reset

2009-04-27T15:54:04+00:00

Diagnostic buffer support is already there in the driver.  This support allows
applications to pull ring buffers from controller firmware for debugging
firmware related issues.

What this patch does is sends reqeust to firmware to release the buffers prior
to host reset.   This will allow what ever debug info is there prior to reset
to be dma'd to host memory. With out this fix, some of the debug data would
been lost.

[SCSI] mpt2sas : Broadcast Primative AEN bug fix

2009-04-27T15:54:02+00:00

Bug fix in the broadcast primative async event code where the driver would
stop sending tm queries after the first queury was completed. This was due
driver not reseting the tm_cmds.status field back to MPT2_CMD_NOT_USED after
completing a task management request.

An addtional fix adding sanity check to insure sas_device->starget set to NULL.
During multipath testing fail over/fail back, the mid layer was holding onto
sdev longer than the fail back period, thus starget was getting set to NULL
for device being added.

[SCSI] mpt2sas : Identify Dell series-7 adapters at driver load time

2009-04-27T15:54:00+00:00

The Dell branding along with the VID, DID, SSVID, SSDID following the LSI
branding that contains the card firmware/chip/bios versions.  If the SSDID
is not known but it is a Dell HBA, the driver will print the SSDID instead
of the Dell branding string.  Nothing will be printed for non Dell HBAs

[SCSI] mpt2sas : driver name needs to be in the MPT2IOCINFO ioctl

2009-04-27T15:53:58+00:00

The driver name needs to be at the beginining of the driver_version string in
MPT2IOCINFO ioctl.  This is the same behaviour is there already in the mptsas
driver.
