From c91a20129185d5153cd845c857b4f9fce61e28d1 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 22 Apr 2025 11:15:55 +0200 Subject: [PATCH] nvmet-auth: authenticate on admin queue only Do not start authentication on I/O queues as it doesn't really add value, and secure concatenation disallows it anyway. Authentication commands on I/O queues are not aborted, so the host may still run the authentication protocol on I/O queues.
