2013-04-25iscsi-target: Initial traditional TCP conversion to iscsit_transportNicholas Bellinger1-4/+7
This patch performs the initial conversion of existing traditional iscsi to use iscsit_transport API callers. This includes: - iscsi-np cleanups for iscsit_transport_type - Add iscsi-np transport calls w/ ->iscsit_setup_up() and ->iscsit_free_np() - Convert login thread process context to use ->iscsit_accept_np() for connections with pre-allocated struct iscsi_conn - Convert existing socket accept code to iscsit_accept_np() - Convert login RX/TX callers to use ->iscsit_get_login_rx() and ->iscsit_put_login_tx() to exchange request/response PDUs - Convert existing socket login RX/TX calls into iscsit_get_login_rx() and iscsit_put_login_tx() - Change iscsit_close_connection() to invoke ->iscsit_free_conn() + iscsit_put_transport() calls. - Add iscsit_register_transport() + iscsit_unregister_transport() calls to module init/exit v4 changes: - Add missing iscsit_put_transport() call in iscsi_target_setup_login_socket() failure case v2 changes: - Update module init/exit to use register_transport() + unregister_transport() Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2011-07-26iscsi-target: Add iSCSI fabric support for target v4.1Nicholas Bellinger1-0/+17
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() (nab: Fix iscsi_proto.h struct scsi_lun usage from linux-next in commit: iscsi: Use struct scsi_lun in iscsi structs instead of u8[8]) (nab: Fix 32-bit compile warnings) Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Andy Grover <agrover@redhat.com> Acked-by: Roland Dreier <roland@kernel.org> Signed-off-by: Nicholas A.
