Annotated Snippet

What:		/sys/devices/virtual/nvme-fabrics/ctl/.../tls_configured_key
Date:		November 2025
KernelVersion:	6.19
Contact:	Linux NVMe mailing list <linux-nvme@lists.infradead.org>
Description:
		The file is avaliable when using a secure concatanation
		connection to a NVMe target. Reading the file will return
		the serial of the currently negotiated key.

		Writing 0 to the file will trigger a PSK reauthentication
		(REPLACETLSPSK) with the target. After a reauthentication
		the value returned by tls_configured_key will be the new
		serial.

Annotation

• Atlas domain: Support Tooling And Documentation / Documentation.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
