## v25.09



### bdev



`spdk_bdev_get_preferred_write_alignment`, `spdk_bdev_get_preferred_write_granularity`,

`spdk_bdev_get_optimal_write_size`, `spdk_bdev_get_preferred_unmap_alignment` and

`spdk_bdev_get_preferred_unmap_granularity` APIs were added.



### bdev_compress



The deprecated bdev_compress module was removed.



### bdev_null



Support was added to set the bdev's preferred write alignment, preferred write

granularity, optimal write size, preferred unmap alignment and preferred unmap

granularity. These can be set by users using new parameters to the `bdev_null_create`

RPC.



### bdev_nvme



Add NVMe flush support to the bdev_nvme module. This support is optional and can be

enabled using the new `enable_flush` parameter to the `bdev_nvme_set_options` RPC.

The flush command is only sent to the namespace if the namespace reported that it

had a volatile write cache.



Support was added to set the bdev's preferred write alignment, preferred write

granularity, optimal write size, preferred unmap alignment and preferred unmap

granularity, if the NVMe namespace reports the associated values in its

IDENTIFY data.



### bdev_rbd



Support was added for read-only RBD bdevs. Users can make an RBD bdev read-only

by using the `-r` or `--readonly` flag with the `bdev_rbd_create` RPC.



### blobfs



The deprecated blobfs library was removed.



### env_dpdk



The DPDK submodule was updated to DPDK 25.07.



Support was added for memory registration at a 4KB granularity.



The deprecated `spdk_env_get_socket_id()` and `spdk_pci_device_get_socket_id()`

APIs were removed. Users should use `spdk_env_get_numa_id()` and

`spdk_pci_device_get_numa_id()` instead.



### nvme



Logging was significantly enhanced as part of this release. Transport address

is now shown for fabrics controllers. QP related log messages now include

information about the QP and its controller.



### nvmf



Add NSSR support (NVMe Subsytem Reset) to NVMe-oF target. Once NSSR is issued - it is passed to all

underlying namespaces (bdevs). Currenly only bdevs with PCIe transport would handle NSSR.

See the NVMe Subsystem Reset (NSSR) section of nvmf.md for more information.



Passthrough handlers for vendor-specific admin commands were added to the NVMe-oF target.

They can be enabled using the optional `vendor_specific` parameter to the `nvmf_set_config`

RPC.



Vfio-user migration code was removed. This code was in a non-working state, and upstream

libvfio-user has moved to a new v2-style interface which is significantly different.

QEMU 10.1 has no live migration support currently, and when it does it will be v2-style

based. This allows SPDK to use latest vfio-user and its vfio-user migration support

is planned to be re-added at a later time.



A namespace's IDENTIFY data is now populated with the preferred write alignment,

preferred write granularity, optimal write size, preferred unmap alignment and

preferred unmap granularity if they were specified by the underlying bdev.



The nvmf target now reports support for NVMe version 1.4. To enable this upgrade,

improved NSID and log page offset validation was added to the target.



### python



Moved all cli code inside the python package for easier generation and packaging.

Changed the return behavior of `spdk_sock_flush`. The function now returns 0 on success, as relying

on the number of bytes returned was not recommended.



### nvmf

Added `spdk_sock_connect_async` to enable asynchronous connect operations.



Add NSSR support (NVMe Subsytem Reset) to NVMe-oF target. Once NSSR is issued - it is passed to all

underlying namespaces (bdevs). Currenly only bdevs with PCIe transport would handle NSSR.

See the NVMe Subsystem Reset (NSSR) section of nvmf.md for more information.

### thread



The `spdk_io_channel_ref` API was added to more efficiently take a reference to an

existing and known I/O channel.



### util



The `spdk_bit_pool_set_bit_allocated` API was added to enable setting an `spdk_bit_pool`

to a previously known state.
