nvme: fix typo in status code constant for self-test in progress

Correct a typo error in the NVMe status code constant from NVME_SC_SELT_TEST_IN_PROGRESS to NVME_SC_SELF_TEST_IN_PROGRESS to accurately reflect its meaning. Signed-off-by: Alok Tiwari Reviewed-by: Randy Dunlap Reviewed-by: Chaitanya Kulkarni Signed-off-by: Christoph Hellwig

nvme: fix command limits status code

2025-06-04T07:51:10+00:00

The command specific status code, 0x183, was introduced in the NVMe 2.0 specification defined to "Command Size Limits Exceeded" and only ever applied to DSM and Copy commands. Fix the name and, remove the incorrect translation to error codes and special treatment in the target code for it.

nvme-tcp: request secure channel concatenation

2025-03-20T23:53:54+00:00

Add a fabrics option 'concat' to request secure channel concatenation as specified the NVME Base Specification v2.1, section 8.3.4.3: Secure Channel Concatenation. When secure channel concatenation is enabled a 'generated PSK' is inserted into the keyring such that it's available after reset.

nvmet: Implement host identifier set feature support

2025-01-11T03:30:48+00:00

The NVMe specifications mandate support for the host identifier set_features for controllers that also supports reservations. Satisfy this requirement by implementing handling of the NVME_FEAT_HOST_ID feature for the nvme_set_features command. This implementation is for now effective only for PCI target controllers. For other controller types, the set features command is failed with a NVME_SC_CMD_SEQ_ERROR status as before. As noted in the code, 128 bits host identifiers are supported since the NVMe base specifications version 2.1 indicate in section 5.1.25.1.28.1 that "The controller may support a 64-bit Host Identifier...". The RHII (Reservations and Host Identifier Interaction) bit of the controller attribute (ctratt) field of the identify controller data is also set to indicate that a host ID of "0" is supported but that the host ID must be a non-zero value to use reservations.

nvme: Add PCI transport type

2025-01-11T03:30:47+00:00

Define the transport type NVMF_TRTYPE_PCI for PCI endpoint targets. This transport type is defined using the value 0 which is reserved in the NVMe base specifications v2.1 (Figure 294). Given that struct nvmet_port are zeroed out on creation, to avoid having this transsport type becoming the new default, nvmet_referral_make() and nvmet_ports_make() are modified to initialize a port discovery address transport type field (disc_addr.trtype) to NVMF_TRTYPE_MAX. Any port using this transport type is also skipped and not reported in the discovery log page (nvmet_execute_disc_get_log_page()). The helper function nvmet_is_pci_ctrl() is also introduced to check if a target controller uses the PCI transport.

nvme: Move opcode string helper functions declarations

2025-01-11T03:30:46+00:00

Move the declaration of all helper functions converting NVMe command opcodes and status codes into strings from drivers/nvme/host/nvme.h into include/linux/nvme.h, together with the commands definitions. This allows NVMe target drivers to call these functions without having to include a host header file.
