nvme: null terminate nvme_tls_attrs

2024-09-25T06:34:13+00:00

Commit 1e48b34c9bc7 ("nvme: split off TLS sysfs attributes into a separate group") introduced the struct attribute array nvme_tls_attrs. However, the array was not null terminated and caused BUG KASAN global- out-of-bounds. To avoid the BUG, null terminate the array.

nvme-sysfs: add 'tls_keyring' attribute

2024-08-22T20:25:11+00:00

Add a 'tls_keyring' attribute to display the contents of the --keyring option from the connect string. Adding this attribute allows us to recreate the original connect string from sysfs settings. Signed-off-by: Hannes Reinecke Reviewed-by: Sagi Grimberg Signed-off-by: Keith Busch

nvme-sysfs: add 'tls_configured_key' sysfs attribute

2024-08-22T20:25:11+00:00

There is a difference between the negotiated TLS key (which is always present for a TLS encrypted connection) and the configured TLS key (which is specified with the --tls_key command line option). To differentate between these two add a new sysfs attribute 'tls_configured_key' to hold the specified on the command line.

nvme-tcp: sanitize TLS key handling

2024-08-22T20:22:41+00:00

There is a difference between TLS configured (ie the user has provisioned/requested a key) and TLS enabled (ie the connection is encrypted with TLS). This becomes important for secure concatenation, where the initial authentication is run on an unencrypted connection (ie with TLS configured, but not enabled), and then the queue is reset to run over TLS (ie TLS configured _and_ enabled). So to differentiate between those two states store the generated key in opts->tls_key (as we're using the same TLS key for all queues), the key serial of the resulting TLS handshake in ctrl->tls_pskid (to signal that TLS on the admin queue is enabled), and a simple flag for the queues to indicated that TLS has been enabled.
