[PATCH 0/2] nvme: restrict authentication to the admin queue

[Hannes Reinecke]

Hi all,

it might be an idea to restrict authentication to the admin queue only,
as authentication on I/O queues brings only so much additional benefit,
and the entire authentication is noticeably faster.
This patchsets enables the host to handle this situation, and adds a
new configfs entry 'dhchap_admin_only' for the target to enable this
behaviour.
Patches are on top of my 'secure-concat.v5' branch on kernel.org.

As usual, comments and reviews are welcome.

  nvme: Do not re-authenticate queues with no prior authentication
  nvmet: Implement 'admin_only' authentication
