* [SCSI] qla2xxx: Correct domain/area exclusion logic.Andrew Vasquez2005-09-04
| | | | | | | | | | | | | | | | | | | | | In an FL topology, limit port recognition to those devices not within the same area and domain of the ISP. The firmware will recogonize such devices during local-loop discovery. Some devices may respond to a PLOGI before they have completed their fabric login or they may not be a public device. In this case they will report: domain == 00 area == 00 alpa == <XX> which is valid. Exclude such devices from local loop discovery.

* [SCSI] qla2xxx: Use dma_get_required_mask() in determining the 'ideal' DMA mask.Andrew Vasquez2005-09-04
| | | | | | | | | | | In order to efficiently utilise the ISP's IOCB request-queue, use the dma_get_required_mask() function to determine the use of command-type 2 or 3 IOCBs when queueing SCSI commands. This applies to ISP2[123]xx chips only, as the ISP24xx uses command-type 7 IOCBs which use 64bit DSDs.

* [SCSI] embryonic RAID classJames Bottomley2005-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea behind a RAID class is to provide a uniform interface to all RAID subsystems (both hardware and software) in the kernel. To do that, I've made this class a transport class that's entirely subsystem independent (although the matching routines have to match per subsystem, as you'll see looking at the code). I put it in the scsi subdirectory purely because I needed somewhere to play with it, but it's not a scsi specific module. I used a fusion raid card as the test bed for this; with that kind of card, this is the type of class output you get: jejb@titanic> ls -l /sys/class/raid_devices/20\:0\:0\:0/ total 0 lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-0 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:0/20:1:0:0/ lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-1 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:1/20:1:1:0/ lrwxrwxrwx 1 root root 0 Aug 16 17:21 device -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:0:0/20:0:0:0/ -r--r--r-- 1 root root 16384 Aug 16 17:21 level -r--r--r-- 1 root root 16384 Aug 16 17:21 resync -r--r--r-- 1 root root 16384 Aug 16 17:21 state So it's really simple: for a SCSI device representing a hardware raid, it shows the raid level, the array state, the resync % complete (if the state is resyncing) and the underlying components of the RAID (these are exposed in fusion on the virtual channel 1). As you can see, this type of information can be exported by almost anything, including software raid. The more difficult trick, of course, is going to be getting it to perform configuration type actions with writable attributes. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] sr.c: Fix getting wrong sizePete Zaitcev2005-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here's the problem. Try to do this on 2.6.12: - Kill udev and HAL - Insert a CD-ROM into a SCSI or USB CD-ROM drive - Run dd if=/dev/scd0 - cat /sys/block/sr0/size - Eject the CD, insert a different one - Run dd if=/dev/scd0 This is likely to do "access beyond the end of device", if you let it - cat /sys/block/sr0/size This shows the size of a previous CD, even though dd was supposed to revalidate the device. - Run dd if=/dev/scd0 The second run of dd works correctly! The bug was introduced in 2.5.31, when Al fixes the recursive opens in partitioning. Before, the code worked like this: - Block layer called cdrom_open directly - cdrom_open called sr_open - sr_open called check_disk_change - check_disk_change called sr_media_change - sr_media_change did cd->needs_disk_change=1 - before returning sr_open tested cd->needs_disk_change and called get_sector_size. In 2.6.12, the check_disk_change is called from cdrom_open only. Thus: - Block layer calls sr_bd_open - sr_bd_open calls cdrom_open - cdrom_open calls sr_open - sr_open tests cd->needs_disk_change, which wasn't set yet; returns - cdrom_open calls check_disk_change - check_disk_change calls sr_media_change - sr_media_change does cd->needs_disk_change=1, but nobody cares Acked by: Alexander Viro <aviro@redhat.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] correct transport class abstraction to work outside SCSIJames Bottomley2005-08-14
| | | | | | | | | | | | | | | | I recently tried to construct a totally generic transport class and found there were certain features missing from the current abstract transport class. Most notable is that you have to hang the data on the class_device but most of the API is framed in terms of the generic device, not the class_device. These changes are two fold - Provide the class_device to all of the setup and configure APIs - Provide and extra API to take the device and the attribute class and return the corresponding class_device Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Symptoms: when remote port disappears for a period of time longer then either nodev_tmo or dev_loss_tmo, the lpfc driver worker thread will stall removing that remote port.

But corresponding node in the lpfc driver is still in the NPR(?node port recovery?) state and mid-layer gets SCSI_MLQUEUE_HOST_BUSY as a return value when it is trying to call queuecommand() with command for that node (AKA remote port) Fix: Instead of returning SCSI_MLQUEUE_HOST_BUS from queuecommand() for nodes in NPR states complete it with retry-able error code DID_BUS_BUSY Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] add global timeout to the scsi mid-layerJames Bottomley2005-08-08
| | | | | | | | | | | | | | | | | | There are certain rogue devices (and the aic7xxx driver) that return BUSY or QUEUE_FULL forever. This code will apply a global timeout (of the total number of retries times the per command timer) to a given command. If it is exceeded, the command is completed regardless of its state. The patch also removes the unused field in the command: timeout and timeout_total. This solves the problem of detecting an endless loop in the mid-layer because of BUSY/QUEUE_FULL bouncing, but will not recover the device. In the aic7xxx case, the driver can be recovered by sending a bus reset, so possibly this should be tied into the error handler? Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Nate's explanation of the changes: I've attached patches against 2.6.13rc2. These are basically identical to my earlier patches, as I found that all issues I'd seen in earlier kernels still existed in this kernel. To summarize, the changes are: (more details in my original email) - add a kref to the scsi_tape structure, and associate reference counting stuff - set sr_request->end_io = blk_end_sync_rq so we get notified when an IO is rejected when the device goes away - check rq_status when IOs complete, else we don't know that IOs rejected for a dead device in fact did not complete - change last_SRpnt so it's set before an async IO is issued (in case st_sleep_done is bypassed) - fix a bogus use of last_SRpnt in st_chk_result Signed-off-by: Nate Dailey <nate.dailey@stratus.com> Signed-off-by: Kai Makisara <kai.makisara@kolumbus.fi> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

The timeout is there to clean up should the management application die and fail to poll for updated AIF event packets. Moving the timer update from the ioctl code that delivers an AIF to the polling registrant to the bottom of the ioctl means the timeout is reset with any management application polling activity regardless if an AIF is delivered or not removing the erroneous timeout cleanups.

* [SCSI] aacraid: interupt mitigationMark Haverkamp2005-08-05
| | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn from Adaptec: If more than two commands are outstanding to the controller, there is no need to notify the adapter via a PCI bus transaction of additional commands added into the queue; it will get to them when it works through the produce/consumer indexes. This reduced the PCI traffic in the driver to submit a command to the queue to near zero allowing a significant number of commands to be turned around with no need to block for the PCI bridge to flush the notify request to the adapter. Interrupt mitigation has always been present in the driver; it was turned off because of a bug that prevented one from realizing the usefulness of the feature. This bug is fixed in this patch.
