SPDK v21.01.1: Maintenance Releases

On behalf of the SPDK community I’m pleased to announce the release of SPDK 21.01.1 LTS.

SPDK 21.01.1 LTS


Added rte_ethdev and rte_net dependencies for all builds with DPDK.

Fixed compatibility issues with DPDK 19.11.


A security vulnerability has been identified and fixed in the SPDK iSCSI target. A TEXT PDU with no data, but CONTINUE flag set, would result in a NULL pointer dereference and crash the SPDK iSCSI target process. All users of the SPDK iSCSI target are recommended to update. All SPDK versions <= v21.01 are affected.


Fixed kernel hang when bdev is removed by always setting NBD_SET_TIMEOUT.


Fixed segfault when removing qpair when transport connection fails (issue #1777).


Fixed the bug that no media event is pushed to the target bdev.


Added enable_quickack and enable_placement_id when saving JSON configuration.

Thanks to everyone for your contributions, participation, and effort!
