nvme: implement In-Band authentication2022-08-02T23:14:49+00:00Hannes Reineckehare@suse.de2022-06-27T09:52:02+00:00urn:sha1:f50fff73d620cd6e8f48bc58d4f1c944615a3fea
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'.
