nvmet-auth: select the intended CRYPTO_DH_RFC7919_GROUPS

2022-08-02T23:22:51Z

Commit 71ebe3842ebe ("nvmet-auth: Diffie-Hellman key exchange support") intends to select 'Support for RFC 7919 FFDHE group parameters' for using FFDHE groups for NVMe In-Band Authentication. It however selects CRYPTO_DH_GROUPS_RFC7919, instead of the intended CRYPTO_DH_RFC7919_GROUPS; notice the swapping of words here. Correct the select to the intended config option.

nvmet: implement basic In-Band Authentication

2022-08-02T23:14:49Z

Implement NVMe-oF In-Band authentication according to NVMe TPAR 8006. This patch adds three additional configfs entries 'dhchap_key', 'dhchap_ctrl_key', and 'dhchap_hash' to the 'host' configfs directory. The 'dhchap_key' and 'dhchap_ctrl_key' entries need to be in the ASCII format as specified in NVMe Base Specification v2.0 section 8.13.5.8 'Secret representation'. 'dhchap_hash' defaults to 'hmac(sha256)', and can be written to to switch to a different HMAC algorithm.

nvme: Have NVME_FABRICS select NVME_CORE instead of transport drivers

2021-08-16T19:03:18Z

Transport drivers need both core and fabrics modules, instead of selecting both, have the selection transitive such that NVME_FABRICS selects NVME_CORE and transport drivers select NVME_FABRICS.

nvmet-tcp: add NVMe over TCP target driver

2018-12-13T08:58:57Z

This patch implements the TCP transport driver for the NVMe over Fabrics target stack. This allows exporting NVMe over Fabrics functionality over good old TCP/IP. The driver implements the TP 8000 of how nvme over fabrics capsules and data are encapsulated in nvme-tcp pdus and exchaged on top of a TCP byte stream. nvme-tcp header and data digest are supported as well.
