ch_probe uses the total number of ch devices as minor. ch_probe: ch->minor = ch_devcount; ... ch_devcount++; Then ch_remove decreases ch_devcount: ch_remove: ch_devcount--; If you have two ch devices, sch0 and sch1, and remove sch0, ch_devcount is 1. Then if you add another ch device, ch_probe tries to create sch1. So you get a warning and fail to create sch1: Jan 24 16:01:05 nice kernel: sysfs: duplicate filename 'sch1' can not be created Jan 24 16:01:05 nice kernel: WARNING: at fs/sysfs/dir.c:424 sysfs_add_one() Jan 24 16:01:05 nice kernel: Pid: 2571, comm: iscsid Not tainted 2.6.24-rc7-ga3d2c2e8-dirty #1 Jan 24 16:01:05 nice kernel: Jan 24 16:01:05 nice kernel: Call Trace: Jan 24 16:01:05 nice kernel: [<ffffffff802a22b8>] sysfs_add_one+0x54/0xbd Jan 24 16:01:05 nice kernel: [<ffffffff802a283c>] create_dir+0x4f/0x87 Jan 24 16:01:05 nice kernel: [<ffffffff802a28a9>] sysfs_create_dir+0x35/0x4a Jan 24 16:01:05 nice kernel: [<ffffffff803069a1>] kobject_get+0x12/0x17 Jan 24 16:01:05 nice kernel: [<ffffffff80306ece>] kobject_add+0xf3/0x1a6 Jan 24 16:01:05 nice kernel: [<ffffffff8034252b>] class_device_add+0xaa/0x39d Jan 24 16:01:05 nice kernel: [<ffffffff803428fb>] class_device_create+0xcb/0xfa Jan 24 16:01:05 nice kernel: [<ffffffff80229e09>] printk+0x4e/0x56 Jan 24 16:01:05 nice kernel: [<ffffffff802a2054>] sysfs_ilookup_test+0x0/0xf Jan 24 16:01:05 nice kernel: [<ffffffff88022580>] :ch:ch_probe+0xbe/0x61a (snip) This patch converts ch to use a standard minor number management way, idr like sg and bsg.

The patch "[SCSI] sg: use idr to replace static arrays" in 2.6.24-rc1 causes a bogus line to appear in /proc/scsi/sg/devices containing "-1 -1 -1 -1 -1 -1 -1 -1 -1" when there are no SCSI devices in the system. In 2.6.23, /proc/scsi/sg/devices is empty when there are no SCSI devices in the system. A similar problem exists with /proc/scsi/sg/device_strs. The following patch restores the behavior of 2.6.23.

This removes static array sense_buffer in scsi_cmnd and uses dynamically allocated sense_buffer (with GFP_DMA). The reason for doing this is that some architectures need cacheline aligned buffer for DMA: http://lkml.org/lkml/2007/11/19/2 The problems are that scsi_eh_prep_cmnd puts scsi_cmnd::sense_buffer to sglist and some LLDs directly DMA to scsi_cmnd::sense_buffer. It's necessary to DMA to scsi_cmnd::sense_buffer safely. This patch solves these issues. __scsi_get_command allocates sense_buffer via kmem_cache_alloc and attaches it to a scsi_cmnd so everything just work as before. Signed-off-by:

Since evidently no-one relies on these being built in, fix this by ensuring they can only be built as modules. Acked-by:

The cards being added are supported in a limited sense already through family matching, but we needed to add some functionality to the driver to expose selectively the physical drives. These Physical drives are specifically marked to not be part of any array and thus are declared JBODs (Just a Bunch Of Drives) for generic SCSI access. We report that this is the second patch in a set of two, but merely depends on the stand-alone functionality of the first patch which adds in that case the ability to report a driver feature flag via sysfs. We leverage that functionality by reporting that this driver now supports this new JBOD feature for the controller so that the array management applications may react accordingly and guide the user as they manage the controller.

Feature enhancement, adding a 'flags' entry that will reside in the host controller's tree, with a newline separated list of arbitrary ascii named features that indicate whether the combination of driver and controller has support for said feature. Breaking from the one-line output typical of sysfs entries, newline was added to tailor for grep, or simple gets line by line string match within an application. I added one for a compiler time check for existence of debug print output, one for an optional manifest defined enhanced status reporting in the logs, and one for runtime reporting whether the controller and driver supports arrays larger than 2TB. Adaptec's storage management software uses the last flag to determine whether to make available the creation of arrays larger than 2TB, otherwise a warning is posted. Signed-off-by:

FCE support enables the firmware to record FC extended link services and basic link services frames which have been transmitted and received by the ISP. This allows for a limited view of the FC traffic through the ISP without using a FC analyzer. This can be useful in situations where a physical connection to the FC bus is not possible. The driver exports this information in two ways -- first, via a debugfs node exported for all supported ISPs under: <debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce where a read of the 'fce' file will provide a snapshot of the firmware's FCE buffer; and finally, the FCE buffer will be extracted during a firmware-dump scenario.

Actually there are several but one is trivially fixed 1. FSACTL_GET_NEXT_ADAPTER_FIB ioctl does not lock dev->fib_list but needs to 2. Ditto for FSACTL_CLOSE_GET_ADAPTER_FIB 3. It is possible to construct an attack via the SRB ioctls where the user obtains assorted elevated privileges. Various approaches are possible, the trivial ones being things like writing to the raw media via scsi commands and the swap image of other executing programs with higher privileges. So the ioctls should be CAP_SYS_RAWIO - at least all the FIB manipulating ones. This is a bandaid fix for #3 but probably the ioctls should grow their own capable checks. The other two bugs need someone competent in that driver to fix them. Signed-off-by:

Due to an internal limit associated with the AdapterTypeText field, SMC required a product ID that overloaded the combined vendor and product ID. A decision was made to ship the SMC products without a vendor string dropping the defacto space that used to delineate vendor and product to boot. To correct this, we needed to adjust the code in the driver to parse out the vendor and product strings for the adapter. We match of 'AOC' in the AdapterTypeText, if so we set the vendor to SMC and place the entire AdapterTypeText into the product field. This only affects the cosmetic presentation of the Adapter vendor and product in the logs and in sysfs. Signed-off-by:
