Updating commands and structures for NVMe 1.1 updates, mostly for nvme reservations. There are no additional in-kernel uses, but this is for the uapi. While doing this, I noticed that the software progress features was using the wrong value, so updating that value as well.

The NVME_IOCTL_SUBMIT_IO only works for IO commands with block data transfers and isn't usable for other NVMe commands like flush, data set management, or any sort of vendor unique command. The NVME_IOCTL_ADMIN_CMD, however, can easily be modified to accept arbitrary IO commands in addition to arbitrary admin commands without breaking backward compatibility. This patch just adds a new IOCTL to distinguish if the driver should submit the command on an IO or Admin queue.

This adds a callback to revalidate the disk and change its block size and capacity if needed. Before, a user would have to remove + rescan an entire device if they changed the logical block size using an NVMe Format or other vendor specific command; now they can just run something that issues the BLKRRPART IOCTL, like # hdparm -z /dev/nvmeXnY This can also be used in response to the 1.2 Spec's Namespace Attribute Change asynchronous event.

We need to update the nvme queue's wait_queue_t entry during each initialization since the nvme_thread may be ended and restarted when the device is reset. If a device reset occurs during a large amount of buffered IO, it would take a lot longer to complete the outstanding requests due to the 1 second polling instead of waking up as completions occur.

This returns a more appropriate error for the "capacity exceeded" status. In case other NVMe statuses have a better errno, this patch adds a convience function to translate an NVMe status code to an errno for IO commands, defaulting to the current -EIO.

We've only been setting the sg_io_hdr status values on SCSI commands that require an nvme command to complete the translation. The fields in the struct are output parameters, so we have to set them, otherwise user space will see whatever was in memory from before. In the case of compat SG_IO, this would reveal kernel memory. This fixes the issue by initializing the sg_io_hdr with successful status.

If an nvme device is removed but user space has an open reference, the nvme driver would have been holding an invalid reference to its pci device. You may get a general protection fault on x86 h/w when the driver uses that reference in dma_map_sg(), as is done in nvme_map_user_pages() from the IOCTL interface. This patch fixes the fault by taking a reference on the pci device and holding it even after device removal until all opens on the nvme device are closed.

nvme_submit_io_cmd() uses smp_processor_id() to pick an IO queue index.

This changes the order of deleting the gendisks so it happens after the nvme IO queues are freed. If a device is removed while a filesystem has associated dirty data, the removal will wait on these to complete before proceeding from del_gendisk, which could have caused deadlock before. The implication of this is that an orderly removal of a responsive device won't necessarily wait for dirty data to be written, but we are not guaranteed the device is even going to respond at this point either.

This is a minor refactor for handling devices that are incapable of IO. The driver previously used special error codes to know that IO queues are unavailable, but we have an online queue count now. This also fixes an issue where the driver successfully sets the queue count, but either is unable to allocate an IO queue or the device can't create one for some reason. If the driver can successfully enable the device and get responses to admin commands, the driver will bring up a character device for managment but not create block devices.

Drivers can now tell blk-mq if they take advantage of the deferred issue through 'last' or not. If they do, don't do queue-direct for sync IO. This is a preparation patch for the nvme conversion. Signed-off-by: NJens Axboe <axboe@fb.com>
-
由 Jens Axboe 提交于
Since we have the notion of a 'last' request in a chain, we can use this to have the hardware optimize the issuing of requests. Add a list_head parameter to queue_rq that the driver can use to temporarily store hw commands for issue when 'last' is true. If we are doing a chain of requests, pass in a NULL list for the first request to force issue of that immediately, then batch the remainder for deferred issue until the last request has been sent. Instead of adding yet another argument to the hot ->queue_rq path, encapsulate the passed arguments in a blk_mq_queue_data structure. This is passed as a constant, and has been tested as faster than passing 4 (or even 3) args through ->queue_rq. Update drivers for the new ->queue_rq() prototype. There are no functional changes in this patch for drivers - if they don't use the passed in list, then they will just queue requests individually like before.

Set max_sectors to the value the drivers provides as hardware limit by default. Linux had proper I/O throttling for a long time and doesn't rely on a artifically small maximum I/O size anymore. By not limiting the I/O size by default we remove an annoying tuning step required for most Linux installation. Note that both the user, and if absolutely required the driver can still impose a limit for FS requests below max_hw_sectors_kb.

Pull audit updates from Eric Paris: "So this change across a whole bunch of arches really solves one basic problem. We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs.

Pull sparc fixes from David Miller: "Here we have two bug fixes: 1) The current thread's fault_code is not setup properly upon entry to do_sparc64_fault() in some paths, leading to spurious SIGBUS. 2) Don't use a zero length array at the end of thread_info on sparc64, otherwise end_of_stack() isn't right" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc: sparc64: Do not define thread fpregs save area as zero-length array. sparc64: Fix corrupted thread fault code.
