This requires fixing a few places that were SCSI-specific to add NVME logic. - NVMe has much simpler command ordering requirements than SCSI. In particular, the HBA is not required to enforce any specific ordering for requests with overlapping LBAs. The host is required to manage that ordering. However, fused commands (currently only COMPARE and WRITE NVM commands can be fused) are required to be executed atomically. To support fused commands, make the second half of a fused command block on the first half, and have commands submitted after a fused command pair block on the second half. - Add handlers and command tables for admin and NVM commands that operate on individual namespaces and will be passed down from an NVMe over Fabrics controller to a CTL LUN.

This allows those without iscsi(4) support built into the kernel to use ctl(4) as a test mechanism. As a sidenote, this was possible around the 10.0-RELEASE period, but made impossible for end-users without iscsi(4) between 10.0-RELEASE and 11.0-RELEASE. Automatically load cfiscsi(4) from ctladm(8) and ctld(8) for backwards compatibility with previously releases. The automatic loading feature is compiled into the beforementioned tools if MK_ISCSI == yes when building world. Add a manpage for cfiscsi(4) and refer to it in ctl(4).

This change includes clean room implementation of the missing code and fixes for many bugs. This code supports dual-node HA with ALUA in four modes: - Active/Unavailable without interlink between nodes; - Active/Standby with second node handling only basic LUN discovery and reservation, synchronizing with the first node through the interlink; - Active/Active with both nodes processing commands and accessing the backing storage, synchronizing with the first node through the interlink; - Active/Active with second node working as proxy, transfering all commands to the first node for execution through the interlink. Unlike original Copan's implementation, depending on specific hardware, this code uses simple custom TCP-based protocol for interlink. It has no authentication, so it should never be enabled on public interfaces. The code may still need some polishing, but generally it is functional.

At some point we may even want to have several ioctl ports. 2015-08-15T13:34:38Z Alexander Motin mav@FreeBSD.org 2015-08-15T13:34:38Z urn:sha1:2f444d157b9fc470c8a4bf69846b2c5fda30eed4 Its idea was to be a simple initiator and execute several commands from kernel level, but FreeBSD never had consumer for that functionality, while its implementation polluted many unrelated places..
