| | | | | | | | | | | | | | | | | | Instead of explicitly calling scsi_req_init() after blk_get_request(), call that function from inside blk_get_request(). Add an .initialize_rq_fn() callback function to the block drivers that need it. Merge the IDE .init_rq_fn() function into .initialize_rq_fn() because it is too small to keep it as a separate function. Keep the scsi_req_init() call in ide_prep_sense() because it follows a blk_rq_init() call.

* block: introduce new block status code typeChristoph Hellwig2017-06-091-9/+11
| | | | | | | | | | | | | | | | | | | | | | | Currently we use nornal Linux errno values in the block layer, and while we accept any error a few have overloaded magic meanings. This patch instead introduces a new blk_status_t value that holds block layer specific status codes and explicitly explains their meaning. Helpers to convert from and to the previous special meanings are provided for now, but I suspect we want to get rid of them in the long run - those drivers that have a errno input (e.g. networking) usually get errnos that don't know about the special block layer overloads, and similarly returning them to userspace will usually return somethings that strictly speaking isn't correct for file system operations, but that's left as an exercise for later. For now the set of errors is a very limited set that closely corresponds to the previous overloaded errno values, but there is some low hanging fruite to improve it. blk_status_t (ab)uses the sparse __bitwise annotations to allow for sparse typechecking, so that we can easily catch places passing the wrong values.

| * scsi: utilize new cdev_device_add helper functionLogan Gunthorpe2017-03-211-36/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver did not set kobj.parent so it likely suffered from a potential use after free race if the user unregistered the device while it was in use. This was not so straightforward a conversion but I think this patch cleans up its probe's error path significantly. This patch adds device_initialize, which is required for cdev_device_add. Then it switches to put_device instead of kfree as recommended by device_initialize's documentation. This removes a lot from the error path which was already in __remove. A couple things needed to be re-ordered to be entirely correct, though. ida_remove is also moved out of __remove and into unregister to simplify things and follow the pattern other devices are using. This also drop an extra unnecessary get_device/put_device in the code. Signed-off-by: Logan Gunthorpe <logang@deltatee.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | | | | Instead of keeping two levels of indirection for requests types, fold it all into the operations. The little caveat here is that previously cmd_type only applied to struct request, while the request and bio op fields were set to plain REQ_OP_READ/WRITE even for passthrough operations.

* | block,scsi: fixup blk_get_request dead queue scenariosJoe Lawrence2014-08-281-2/+2
|/ | | | | | | | | | | | | | | | | | The blk_get_request function may fail in low-memory conditions or during device removal (even if __GFP_WAIT is set). To distinguish between these errors, modify the blk_get_request call stack to return the appropriate ERR_PTR. Verify that all callers check the return status and consider IS_ERR instead of a simple NULL pointer check. For consistency, make a similar change to the blk_mq_alloc_request leg of blk_get_request. It may fail if the queue is dead, or the caller was unwilling to wait.

Add a blk_rq_set_block_pc() that sets the command type to REQ_TYPE_BLOCK_PC, and properly initializes the members associated with this type of request. Update callers to use this function instead of manipulating rq->cmd_type directly. Includes fixes from Christoph Hellwig <hch@lst.de> for my half-assed attempt.

| | | | | | | | | | | | | | | | | | | | | | | This patch adds the support for the following two read-only sysfs attributes to scsi_osd class members : osdname & systemid These attributes will show up as below in sysfs class hierarchy: /sys/class/scsi_osd/osdX/osdname /sys/class/scsi_osd/osdX/systemid The osdname & systemid are OSD device attributes which uniquely identify a device on the network, while it's IP and certainly it's /dev/osdX device path might change. Userspace utilities (e.g. mkfs.exofs) can parse these attributes to identify the correct OSD in safer and faster way. (Today osd apps open each device in the system and send a attributes query for these, in order to access the user requested device) Signed-off-by: Sachin Bhamare <sbhamare@panasas.com> Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
* [SCSI] osd_uld: Bump MAX_OSD_DEVICES from 64 to 1,048,576Boaz Harrosh2012-02-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | It used to be that minors where 8 bit. But now they are actually 20 bit. So the fix is simplicity itself. I've tested with 300 devices and all user-mode utils work just fine. I have also mechanically added 10,000 to the ida (so devices are /dev/osd10000, /dev/osd10001 ...) and was able to mkfs an exofs filesystem and access osds from user-mode. All the open-osd user-mode code uses the same library to access devices through their symbolic names in /dev/osdX so I'd say it's pretty safe. (Well tested) This patch is very important because some of the systems that will be deploying the 3.2 pnfs-objects code are larger than 64 OSDs and will stop to work properly when reaching that number.
