* [SCSI] Workaround for disks that report bad optimal transfer lengthMartin K. Petersen2013-06-24
| | | | | | | | | | | | | Not all disks fill out the VPD pages correctly. Add a blacklist flag that allows us ignore the SBC-3 VPD pages for a given device. The BLIST_SKIP_VPD_PAGES flag triggers our existing skip_vpd_pages scsi_device parameter to bypass VPD scanning. Also blacklist the offending Seagate drive model.

* [SCSI] bfa: fix faulty handling of events in lps smVijay Mohan Guvva2013-06-04
| | | | | | | | | | | | | | | | | | | When a switch disable/enable or a reboot is done, the HBA port gets an offline and a subsequent online notification. When the port comes up a link up notification is sent to bfa from the firmware. The bfa then send an FLOGI to the firmware which is sent out on the wire. The switch port meanwhile goes offline (presumably for diagnostics) which causes the switch not to respond to the FLOGI. The link down notification is sent to the HBA driver. However owing to a bug in the lps state machine handling the lps state machine does not move to sm_init state (it remains in sm_login state and send a login complete message to fcs). This results in a zero PID assignment as the login is not really complete. This fix is to correctly handle the events in lps state machine.

* [SCSI] Allow error handling timeout to be specifiedMartin K. Petersen2013-06-04
| | | | | | | | | | | Introduce eh_timeout which can be used for error handling purposes. This was previously hardcoded to 10 seconds in the SCSI error handling code. However, for some fast-fail scenarios it is necessary to be able to tune this as it can take several iterations (bus device, target, bus, controller) before we give up. Signed-off-by: Martin K.

* [SCSI] sd: avoid deadlocks when running under multipathHannes Reinecke2013-06-04
| | | | | | | | | | | | | | | | | | | When multipathed systems run into an all-paths-down scenario all devices might be dropped, too. This causes 'del_gendisk' to be called, which will unregister the kobj_map->probe() function for all disk device numbers. When the device comes back the default ->probe() function is run which will call __request_module(), which will deadlock. As 'del_gendisk' typically does _not_ trigger a module unload the default ->probe() function is pointless anyway. This patch implements a dummy ->probe() function, which will just return NULL if the disk is not registered. This will avoid the deadlock. Plus it'll speed up device scanning.

| * | [SCSI] ufs: Correct the expected data transfersizeVinayak Holikatti2013-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch corrects the expected data transfer size of the command UPIU. The current implementation of cmd->transfersize is wrong as it probably equal to sector size. With this implementation the transfer size is updated correctly Reported-by: KOBAYASHI Yoshitake <yoshitake.kobayashi@toshiba.co.jp> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Namjae Jeon <linkinjeon@gmail.com> Reviewed-by: Subhash Jadavani <subhashj@codeaurora.org> Tested-by: Maya Erez <merez@codeaurora.org> Signed-off-by: Santosh Yaraganavi <santoshsy@gmail.com> Signed-off-by: Vinayak Holikatti <vinholikatti@gmail.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

| * | [SCSI] sd: fix array cache flushing bug causing performance problemsJames Bottomley2013-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some arrays synchronize their full non volatile cache when the sd driver sends a SYNCHRONIZE CACHE command. Unfortunately, they can have Terrabytes of this and we send a SYNCHRONIZE CACHE for every barrier if an array reports it has a writeback cache. This leads to massive slowdowns on journalled filesystems. The fix is to allow userspace to turn off the writeback cache setting as a temporary measure (i.e. without doing the MODE SELECT to write it back to the device), so even though the device reported it has a writeback cache, the user, knowing that the cache is non volatile and all they care about is filesystem correctness, can turn that bit off in the kernel and avoid the performance ruinous (and safety irrelevant) SYNCHRONIZE CACHE commands. The way you do this is add a 'temporary' prefix when performing the usual cache setting operations, so echo temporary write through > /sys/class/scsi_disk/<disk>/cache_type Reported-by: Ric Wheeler <rwheeler@redhat.com> Cc: <stable@vger.kernel.org> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

| * | [SCSI] scsi_debug: fix logical block provisioning supportAkinobu Mita2013-05-02

So the allocation size should be a multiple of sizeof(unsigned long) and also the bitmap should be cleared by using bitmap_clear() instead of memset(). Otherwise it will cause problem on big-endian architecture if the number of bits is not a multiple of BITS_PER_LONG. I tried testing the logical block provisioning support in scsi_debug, but it didn't work as I expected. For example, load scsi_debug module with UNMAP command supported and fill the storage with random data. # modprobe scsi_debug lbpu=1 # dd if=/dev/urandom of=/dev/sdb Then, try to unmap LBA 0, but Get LBA status reports: # sg_unmap --lba=0 --num=1 /dev/sdb # sg_get_lba_status --lba=0 /dev/sdb descriptor LBA: 0x0000000000000000 blocks: 16384 mapped This is unexpected result. Because UNMAP command to LBA 0 finished without any errors, but Get LBA status shows that LBA 0 is still mapped. This problem is due to the wrong translation between LBA and index of provisioning map. Fix it by using correct translation functions.
