[SCSI] ipr: Fix HDIO_GET_IDENTITY oops for SATA devices

2008-07-11T18:45:48Z

Currently, ipr does not support HDIO_GET_IDENTITY to SATA devices. An oops occurs if userspace attempts to send the command. Since hald issues the command, ensure we fail the ioctl in ipr. This is a temporary solution to the oops. Once the ipr libata EH conversion is upstream, ipr will fully support HDIO_GET_IDENTITY.

[SCSI] erase invalid data returned by device

2008-07-06T16:33:08Z

This patch (as1108) fixes a problem that can occur with certain USB mass-storage devices: They return invalid data together with a residue indicating that the data should be ignored. Rather than leave the invalid data in a transfer buffer, where it can get misinterpreted, the patch clears the invalid portion of the buffer. This solves a problem (wrong write-protect setting detected) reported by Maciej Rutecki and Peter Teoh. Signed-off-by: Alan Stern Tested-by: Peter Teoh Signed-off-by: James Bottomley

[SCSI] esp: tidy up target reference counting

2008-06-25T17:36:13Z

The esp driver currently does hand rolled reference counting of its target. It's much easier to do what it needs to do if it's plugged into the mid-layer callbacks (target_alloc and target_destroy) which were designed for this case, so do it this way and get rid of the internal target reference count.

[SCSI] esp: Fix OOPS in esp_reset_cleanup().

2008-06-24T20:48:56Z

OOPS reported by Friedrich Oslage The problem here is that tp->starget is set every time a lun is allocated for a particular target so we can catch the sdev_target parent value. The reset handler uses the NULL'ness of this value to determine which targets are active. But esp_slave_destroy() does not NULL out this value when appropriate. So for every target that doesn't respond, the SCSI bus scan causes a stale pointer to be left here, with ensuing crashes like you're seeing. Signed-off-by: David S.

[SCSI] dpt_i2o: Add PROC_IA64 define

2008-06-15T16:12:20Z

This fixes the following compile failure: drivers/scsi/dpt_i2o.c:83: error: 'PROC_IA64' undeclared here (not in a function) Mark Salyzyn indicated that IA64 must report itself as PROC_INTEL, so I've changed the comment for PROC_INTEL.

[SCSI] scsi_host regression: fix scsi host leak

2008-06-15T16:09:43Z

commit 9c7701088a61cc0cf8a6e1c68d1e74e3cc2ee0b7 Author: Dave Young Date: Tue Jan 22 14:01:34 2008 +0800 scsi: use class iteration api Isn't a correct replacement for the original hand rolled host lookup. The problem is that class_find_child would get a reference to the host's class device which is never released. Since the host class device holds a reference to the host gendev, the host can never be freed. In 2.6.26 we started using class_find_device, and this function also gets a reference to the device, so we end up with an extra ref and the host will not get released. This patch adds a put_device to balance the class_find_device() get. I kept the scsi_host_get in scsi_host_lookup, because the target layer is using scsi_host_lookup and it looks like it needs the SHOST_DEL check.

[SCSI] sr: fix corrupt CD data after media change and delay

2008-06-10T15:31:23Z

Reported-by: Geert Uytterhoeven If you delay 30s or more before mounting a CD after inserting it then the kernel has the wrong value for the CD size. http://marc.info/?t=121276133000001 The problem is in sr_test_unit_ready(): the function eats unit attentions without adjusting the sdev->changed status. This means that when the CD signals changed media via unit attention, we can ignore it. Fix by making sr_test_unit_ready() adjust the changed status.
