    iscsi-target: Add iSCSI fabric support for target v4.1 · e48354ce
    Nicholas Bellinger authored
    The Linux-iSCSI.org target module is a full featured in-kernel
    software implementation of iSCSI target mode (RFC-3720) for the
    current WIP mainline target v4.1 infrastructure code for the v3.1
    kernel.  More information can be found here:
    
    http://linux-iscsi.org/wiki/ISCSI
    
    
    
    This includes support for:
    
       * RFC-3720 defined request / response state machines and support for
         all defined iSCSI operation codes from Section 10.2.1.2 using libiscsi
         include/scsi/iscsi_proto.h PDU definitions
       * Target v4.1 compatible control plane using the generic layout in
         target_core_fabric_configfs.c and fabric dependent attributes
         within /sys/kernel/config/target/iscsi/ subdirectories.
       * Target v4.1 compatible iSCSI statistics based on RFC-4544 (iSCSI MIBS)
       * Support for IPv6 and IPv4 network portals in M:N mapping to TPGs
       * iSCSI Error Recovery Hierarchy support
       * Per iSCSI connection RX/TX thread pair scheduling affinity
       * crc32c + crc32c_intel SSEv4 instruction offload support using libcrypto
       * CHAP Authentication support using libcrypto
       * Conversion to use internal SGl allocation with iscsit_alloc_buffs() ->
         transport_generic_map_mem_to_cmd()
