SPDK v24.05: NVMe in-band authentication, keyring lib, blob shallow copy

•

On behalf of the SPDK community I’m pleased to announce the release of SPDK 24.05!!

This release contains the following new features:

  • NVMe In-Band Authentication: NVMe driver and NVMe-oF target now supports DH-HMAC-CHAP protocol for in-band authentication.
  • Keyring Library: New library responsible for providing access to cryptographic keys. The module interface is pluggable with keyring_file and keyring_linux modules implemented.
  • Blobstore Shallow Copy: Enables copying of read-only blobs such that only allocated clusters are written on the device. This functionality extends to logical volumes.
  • DIF Operations in Accel: Accel now supports verify-copy operation for Data Integrity Field (DIF) computation. Supported by software and DSA accel modules.
  • NVMe-oF mDNS Pull Registration Requests: Support added for mDNS-based discovery of NVMe-oF target for TCP transport.
  • RAID1 I/O Error Handling: RAID1 can now recover from I/O errors when redundancy permits.

The full changelog for this release is available here. Deprecation notices for users updating from previous releases can be found here.
