[PATCHv2 0/2] nvme: restrict authentication to the admin queue

[hare@kernel.org]

From: Hannes Reinecke <hare@kernel.org>

Hi all,

with secure concatenation the spec got more explicit to state that it
would be perfectly fine to implement authentication on the admin queue only.
But once a partner implemented that he found that re-authentication was
failing as we continue to start authentication on all queues.
So these two patches implement this functionalify, the first one on
the target (to have a testbed to test against), and the second one
to the host to have it fixed.
Patches are on top of my 'secure-concat.v14' branch on kernel.org.

As usual, comments and reviews are welcome.

Changes to the original submission:
- Rebased to nvme-6.14

Hannes Reinecke (2):
  nvmet: Implement 'admin_only' authentication
  nvme: Do not re-authenticate queues with no prior authentication
