Added API `spdk_accel_submit_xor` to perform XOR.



Configuration of `mlx5_pci` driver of accel_dpdk_cryptodev module was changed. Now key and key2 should have equal

length and key size in hexlified form can be either 32 bytes for 128b XTS key or 64 bytes for 256b XTS key.

Support of the wrapped crypto credentials mode for this driver is dropped, only plain text mode is supported.

dropped, only plain text mode is supported.



The accel library will now collect statistics on the number of executed operations and processed

bytes.  These statistics can be retreived using the `accel_get_stats` RPC.



Added support for appending a crc32 calculation to an accel sequence.



### bdev
@@ -24,14 +30,24 @@ a specified LBA range. 
Removed `spdk_bdev_ext_io_opts` from `spdk_bdev_io` and replaced it with fields that were missing in

`spdk_bdev_io`.



It is now possible to submit an I/O with an associated accel sequence.  All operations in such

sequence will be executed prior to sending the I/O (writes) or after its completion (reads).



### env



New functions `spdk_env_get_main_core` and `spdk_env_get_cpuset` were added.



It is now possible to run applications on cores with IDs greater than 128 by passing a core map

using the `--lcores` parameter.



### gpt



GPT bdevs now use the GPT Unique Partition ID as the bdev's UUID.



### idxd



Removed the `SPDK_IDXD_FLAG_PERSISTENT` flag.



### lvol



New API `spdk_lvol_iter_immediate_clones` was added to iterate the clones of an lvol.

associated with specific lvol stores and for listing lvols that are degraded and have no

Added support for external snapshots making it possible to create clones of any (including non-lvol)

bdev.  Users can create such clones using the `bdev_lvol_clone_bdev` RPC.

Parameters `cb_fn` and `ctx` of `spdk_nvmf_qpair_disconnect` API are deprecated. These parameters

Added a secure_channel parameter to the nvmf_subsystem_add_listener RPC. When true, all connections

established via this listener will immediately attempt to establish a secure channel, prior to any

authentication. Only valid for the TCP transport.

Added a `secure_channel` parameter to the `nvmf_subsystem_add_listener` RPC. When true, all

connections established via this listener will immediately attempt to establish a secure channel,

prior to any authentication. Only valid for the TCP transport.



Added two optional transport module callbacks: `subsystem_add_host()` and `subsystem_remove_host()`.

These functions will notify a transport about adding/removing hosts' access.



TLS PSK identity is now generated from subsystem NQN and host NQN.



PSK interchange format is now expected as input, when configuring TLS in SPDK.



TLS feature in SPDK is considered experimental

expected as input, when configuring TLS in SPDK.  TLS feature is considered experimental.



### sock



Added a zero copy receive interface allowing users to provide buffers to a socket group (via

`spdk_sock_group_provide_buf()`), which will then get filled with the next portions of the stream on

each socket.  After that, pointer to the buffer holding the next part of the data can be obtained

using `spdk_sock_recv_next()`.



Added a callback `get_key()` to `spdk_sock_impl_opts` structure.



New function `spdk_sock_get_impl_name()` was added to retrieve current socket implementation name.

Added two new APIs `spdk_thread_bind` and `spdk_thread_is_bound` to bind or unbind `spdk_thread`

the existing worker and namespace association logic to access every namespace from each worker.

This replicates behavior of bdevperf application when `-C` option is provided.



### ublk



Enabled support for `UBLK_F_NEED_GET_DATA`.  The buffers are no longer pre-allocated during

initialization, but are allocated on-demand.  Additionally, they're now allocated from the `iobuf`

buffer pools.



### util



New APIs `spdk_uuid_is_null` and `spdk_uuid_set_null` were added to compare and

set UUID to NULL value.



Added new functions, `spdk_fd_group_{nest,unnest}`, providing efficient way of adding one

`fd_group`'s file descriptors to another `fd_group`.
