2023-10-17nvme-auth: use transformed key size to create respMark O'Donovan
This does not change current behaviour as the driver currently verifies that the secret size is the same size as the length of the transformation hash.

2022-08-02nvme: implement In-Band authenticationHannes Reinecke
Implement NVMe-oF In-Band authentication according to NVMe TPAR 8006. This patch adds two new fabric options 'dhchap_secret' to specify the pre-shared key (in ASCII respresentation according to NVMe 2.0 section 8.13.5.8 'Secret representation') and 'dhchap_ctrl_secret' to specify the pre-shared controller key for bi-directional authentication of both the host and the controller. Re-authentication can be triggered by writing the PSK into the new controller sysfs attribute 'dhchap_secret' or 'dhchap_ctrl_secret'.
