Moving to DELETING state before nvme_tcp_create_ctrl() allocates all the resources may leads to NULL dereference at teardown flow (e.g., IO tagset, admin_q, connect_q).

2020-03-26nvme: Fix controller creation races with teardown flowIsrael Rukshin
Calling nvme_sysfs_delete() when the controller is in the middle of creation may cause several bugs. If the controller is in NEW state we remove delete_controller file and don't delete the controller. The user will not be able to use nvme disconnect command on that controller again, although the controller may be active. Other bugs may happen if the controller is in the middle of create_ctrl callback and nvme_do_delete_ctrl() starts. For example, freeing I/O tagset at nvme_do_delete_ctrl() before it was allocated at create_ctrl callback. To fix all those races don't allow the user to delete the controller before it was fully created.

2020-03-26nvme: Make nvme_uninit_ctrl symmetric to nvme_init_ctrlIsrael Rukshin
Put the ctrl reference count at nvme_uninit_ctrl as opposed to nvme_init_ctrl which takes it. This decrease the reference count at the core layer instead of decreasing it on each transport separately. Also move the call of nvme_uninit_ctrl at PCI driver after calling to nvme_release_prp_pools and nvme_dev_unmap, in order to put the reference count after using the dev. This is safe because those functions use nvme_dev which is freed only later at nvme_pci_free_ctrl.

In case nvme_sysfs_delete() is called by the user before taking the ctrl reference count, the ctrl may be freed during the creation and cause the bug. Take the reference as soon as the controller is externally visible, which is done by cdev_device_add() in nvme_init_ctrl().

2020-03-26nvme: Add compat_ioctl handler for NVME_IOCTL_SUBMIT_IOmasahiro31.yamada@kioxia.com
Currently 32 bit application gets ENOTTY when it calls compat_ioctl with NVME_IOCTL_SUBMIT_IO in 64 bit kernel. The cause is that the results of sizeof(struct nvme_user_io), which is used to define NVME_IOCTL_SUBMIT_IO, are not same between 32 bit compiler and 64 bit compiler. * 32 bit: the result of sizeof nvme_user_io is 44. * 64 bit: the result of sizeof nvme_user_io is 48. 64 bit compiler seems to add 32 bit padding for multiple of 8 bytes. This patch adds a compat_ioctl handler. The handler replaces NVME_IOCTL_SUBMIT_IO32 with NVME_IOCTL_SUBMIT_IO in case 32 bit application calls compat_ioctl for submit in 64 bit kernel. Then, it calls nvme_ioctl as usual. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Masahiro Yamada (KIOXIA) <masahiro31.yamada@kioxia.com> Signed-off-by: Keith Busch <kbusch@kernel.org>

2020-03-26nvme-multipath: do not reset on unknown statusJohn Meneghini
The nvme multipath error handling defaults to controller reset if the error is unknown. There are, however, no existing nvme status codes that indicate a reset should be used, and resetting causes unnecessary disruption to the rest of IO. Change nvme's error handling to first check if failover should happen. If not, let the normal error handling take over rather than reset the controller.

2020-03-26nvmet-rdma: allocate RW ctxs according to mdtsMax Gurtovoy
Current nvmet-rdma code allocates MR pool budget based on queue size, assuming both host and target use the same "max_pages_per_mr" count. After limiting the mdts value for RDMA controllers, we know the factor of maximum MR's per IO operation. Thus, make sure MR pool will be sufficient for the required IO depth and IO size. That is, say host's SQ size is 100, then the MR pool budget allocated currently at target will also be 100 MRs. But 100 IO WRITE Requests with 256 sg_count(IO size above 1MB) require 200 MRs when target's "max_pages_per_mr" is 128.

Some transports, such as RDMA, would like to set the Maximum Data Transfer Size (MDTS) according to device/port/ctrl characteristics. This will enable the transport to set the optimal MDTS according to controller needs and device capabilities. Add a new nvmet transport op that is called during ctrl identification. This will not effect transports that don't implement this option. The return value of the new op is according to the NVMe spec definition for MDTS.

2020-03-26nvme-tcp: optimize queue io_cpu assignment for multiple queue mapsSagi Grimberg
Currently, queue io_cpu assignment is done sequentially for default, read and poll queues based on queue id. This causes miss-alignment between context of CPU initiating I/O and the I/O worker thread processing queued requests or completions. Change to modify queue io_cpu assignment to take into account queue maps offset. Each queue io_cpu will start at zero for each queue map. This essentially aligns read/poll queues to start over the same range as default queues. Testing performed by Mark with: - ram device (nvmet) - single CPU core (pinned) - 100% 4k reads - engine io_uring (not using sq_thread option) - hipri flag set Micro-benchmark results show a net gain of: - increase of 18%-29% in IOPs - reduction of 16%-22% in average latency - reduction of 7%-23% in 99.99% latency Baseline: ======== QDepth/Batch | IOPs [k] | Avg.
