* remove blk_register_filter and blk_unregister_filter in gendiskFUJITA Tomonori2008-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch remove blk_register_filter and blk_unregister_filter in gendisk, and adds them to sd.c, sr.c. and ide-cd.c The commit abf5439370491dd6fbb4fe1a7939680d2a9bc9d4 moved cmdfilter from gendisk to request_queue. It turned out that in some subsystems multiple gendisks share a single request_queue. So we get: Using physmap partition information Creating 3 MTD partitions on "physmap-flash": 0x00000000-0x01c00000 : "User FS" 0x01c00000-0x01c40000 : "booter" kobject (8511c410): tried to init an initialized object, something is seriously wrong.

* block: move cmdfilter from gendisk to request_queueFUJITA Tomonori2008-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | cmd_filter works only for the block layer SG_IO with SCSI block devices. It breaks scsi/sg.c, bsg, and the block layer SG_IO with SCSI character devices (such as st). We hit a kernel crash with them. The problem is that cmd_filter code accesses to gendisk (having struct blk_scsi_cmd_filter) via inode->i_bdev->bd_disk. It works for only SCSI block device files. With character device files, inode->i_bdev leads you to struct cdev. inode->i_bdev->bd_disk->blk_scsi_cmd_filter isn't safe. SCSI ULDs don't expose gendisk; they keep it private. bsg needs to be independent on any protocols. We shouldn't change ULDs to expose their gendisk. This patch moves struct blk_scsi_cmd_filter from gendisk to request_queue, a common object, which eveyone can access to. The user interface doesn't change; users can change the filters via /sys/block/. gendisk has a pointer to request_queue so the cmd_filter code accesses to struct blk_scsi_cmd_filter.

| * [SCSI] ibmvfc: Fixup host state during reinitBrian King2008-08-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If an ELS is received while the virtual fibre channel adapter is going through its discovery, a flag is set which causes discovery to get re-driven. However, the hosts's state does not get set back to IBMVFC_INITIALIZING and scsi_block_requests does not get called again, which can result in queuecommand ops getting sent during discovery. This should not occur and may cause problems. One example is that we may no longer be logged into the target we send the command to, resulting in a failure which should not have occurred.

| | | | | | | | | | | | | | | | | | | | | | | | This fixes a hang on module removal. The module removal code was setting the hosts's state to IBMVFC_HOST_OFFLINE before tearing down the kernel thread, but, due to a bug in ibmvfc_wait_while_resetting, was not waiting for the kernel thread's offlining work to be done prior to destroying the kernel thread, which left the scsi host in a blocked state which we never got out of.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During internal testing, we've seen issues (hangs) with the 'deferred' vport tear-down-processing typically accompanied with the fc_remove_host() call. This is due to the current implementation's back-end vport handling being performed by the physical-HA's DPC thread where premature shutdown could lead to latent vport requests without a processor. This should also address a problem reported by Gal Rosen (http://marc.info/?l=linux-scsi&m=121731664417358&w=2) where the driver would attempt to awaken a previously torn-down DPC thread from interrupt context by implicitly calling wake_up_process() rather than the driver's qla2xxx_wake_dpc() helper. Rather, than reshuffle the remove_one() device-removal code, during unload, depend on the driver's timer to wake-up the DPC process, by limiting wake-ups based on an 'unloading' flag.

It turns out that prior to the SCST software reloading and returning it's "target-capable" abilities in the PRLI payload, the HBA would be re-initialized as an initiator-only type port. Since initiators typically classify themselves as an FCP-2 capable device, both software and firmware do not perform an explicit logout during port-loss. Unfortunately, as can be seen by the failure case, when the port (now target-capable) returns, firmware performs an ADISC without a follow-on PRLI, leaving stale 'initiator-only' data in the firmware's port database. Correct the discrepancy by performing the explicit logout during the transport's request to terminate-rport-io, thus synchronizing port states and ensuring a follow-on PRLI is performed.

| |/ | | | | | | | | | | | | | | | | | | | | | | This reverts commit 2b142900784c6e38c8d39fa57d5f95ef08e735d8, since it seems to break some other USB storage devices (at least a JMicron USB to ATA bridge). As such, while it apparently fixes some cardreaders, it would need to be made conditional on the exact reader it fixes in order to avoid causing regressions.

| * [SCSI] extend the last_sector_bug flag to cover more sectorsAlan Jenkins2008-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.
