* [SCSI] replace __FUNCTION__ with __func__Harvey Harrison2008-07-2749-235/+235

* [SCSI] extend the last_sector_bug flag to cover more sectorsAlan Jenkins2008-07-273-7/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last_sector_bug flag was added to work around a bug in certain usb cardreaders, where they would crash if a multiple sector read included the last sector. The original implementation avoids this by e.g. splitting an 8 sector read which includes the last sector into a 7 sector read, and a single sector read for the last sector. The flag is enabled for all USB devices. This revealed a second bug in other usb cardreaders, which crash when they get a multiple sector read which stops 1 sector short of the last sector. Affected hardware includes the Kingston "MobileLite" external USB cardreader and the internal USB cardreader on the Asus EeePC. Extend the last_sector_bug workaround to ensure that any access which touches the last 8 hardware sectors of the device is a single sector long. Requests are shrunk as necessary to meet this constraint. This gives us a safety margin against potential unknown or future bugs affecting multi-sector access to the end of the device. The two known bugs only affect the last 2 sectors. However, they suggest that these devices are prone to fencepost errors and that multi-sector access to the end of the device is not well tested. Popular OS's use multi-sector accesses, but they rarely read the last few sectors. Linux (with udev & vol_id) automatically reads sectors from the end of the device on insertion. It is assumed that single sector accesses are more thoroughly tested during development.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following commit causes ch_remove oops: commit 24b42566c3fcbb5a9011d1446783d0f5844ccd45 Author: Greg Kroah-Hartman <gregkh@suse.de> Date: Fri May 16 17:55:12 2008 -0700 SCSI: fix race in device_create There is a race from when a device is created with device_create() and then the drvdata is set with a call to dev_set_drvdata() in which a sysfs file could be open, yet the drvdata will be NULL, causing all sorts of bad things to happen. This patch fixes the problem by using the new function, device_create_drvdata(). It fixes the problem in all of the scsi drivers that need it. Cc: Kay Sievers <kay.sievers@vrfy.org> Cc: Doug Gilbert <dgilbert@interlog.com> Cc: James E.J. Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> The problem is ch_probe stores ch's private data at a wrong place. We need to store it at scsi_device->sdev_gendev but the above patch stores it at device struct that device_create_drvdata returns. So we hit an oops when ch_remove accesses scsi_device->sdev_gendev->driver_data, which is NULL. Actually, there wasn't a race because ch doesn't create sysfs files with device struct that device_create returns. This patch puts back dev_set_drvdata() to set ch's private data properly.

The controller has no knowledge of the protection capabilities of the target device so this information must be passed in the scsi_cmnd. - The protection operation tells the HBA whether to generate, strip or verify protection information. - The protection type tells the HBA which layout the target is formatted with. This is necessary because the controller must be able to correctly interpret the included protection information in order to verify it. - When a scsi_cmnd is reused for error handling the protection operation must be cleared and saved while error handling is in progress. - prot_op and prot_type are placed in an existing hole in scsi_cmnd and don't cause the structure to grow.

* [SCSI] fix shared tag map tag allocationMike Christie2008-07-261-0/+15
| | | | | | | | | | | | | | | | | | | When drivers use a shared tag map we can end up with more requests than tags, because the tag map is shost->can_queue tags and there can be sdevs * sdev->queue_depth requests. In scsi_request_fn if tag allocation fails we just drop down to just dequeueing the tag without a tag. The problem is that drivers using the shared tag map rely on a valid tag always being set, because it will use the tag number to lookup commands later. This patch has us check if we got a valid tag when the host lock is held right before we check if the host queue is ready. We do the check here because to allocate the tag we need the q lock, but if the tag is bad we want to add the device/q onto the starved list which requires the host lock.

We do not need to touch the tag map sizing because the drivers had setup that map according to their can_queue limits when the shared map was created. The scsi mid layer in request_fn will then handle the case where we have more requests than available tags when it checks the host queue ready function.
