2023-11-07nvme: common: make keyring and auth separate modulesArnd Bergmann1-5/+2
When only the keyring module is included but auth is not, modpost complains about the lack of a module license tag: ERROR: modpost: missing MODULE_LICENSE() in drivers/nvme/common/nvme-common.o Address this by making both modules buildable standalone, removing the now unnecessary CONFIG_NVME_COMMON symbol in the process. Also, now that NVME_KEYRING config symbol can be either a module or built-in, the stubs need to check for '#if IS_ENABLED' rather than a simple '#ifdef'.

2023-10-12nvme: rework NVME_AUTH Kconfig selectionHannes Reinecke1-0/+9
Having a single Kconfig symbol NVME_AUTH conflates the selection of the authentication functions from nvme/common and nvme/host, causing kbuild robot to complain when building the nvme target only. So introduce a Kconfig symbol NVME_HOST_AUTH for the nvme host bits and use NVME_AUTH for the common functions only. And move the CRYPTO selection into nvme/common to make it easier to read.

2023-10-11nvme-keyring: register '.nvme' keyringHannes Reinecke1-0/+4
Register a '.nvme' keyring to hold keys for TLS and DH-HMAC-CHAP and add a new config option NVME_KEYRING. We need a separate keyring for NVMe as the configuration is done via individual commands (eg for configfs), and the usual per-session or per-process keyrings can't be used.

2022-08-02nvme: implement In-Band authenticationHannes Reinecke1-0/+4
Implement NVMe-oF In-Band authentication according to NVMe TPAR 8006. This patch adds two new fabric options 'dhchap_secret' to specify the pre-shared key (in ASCII respresentation according to NVMe 2.0 section 8.13.5.8 'Secret representation') and 'dhchap_ctrl_secret' to specify the pre-shared controller key for bi-directional authentication of both the host and the controller. Re-authentication can be triggered by writing the PSK into the new controller sysfs attribute 'dhchap_secret' or 'dhchap_ctrl_secret'.
