This patch adds the kernel module ib_srpt SCSI RDMA Protocol (SRP) target implementation conforming to the SRP r16a specification for the mainline drivers/target infrastructure. This driver was originally developed by Vu Pham and has been optimized by Bart Van Assche and merged into upstream LIO based on his srpt-lio-4.1 branch here: https://github.com/bvanassche/srpt-lio/commits/srpt-lio-4.1/ This updated patch also contains the following two changes from lio-core-2.6.git/master. One is to fix a bug with 1 >= task->task_sg[] chained mappings in ib_srpt, and the other to convert the configfs control plane to reference IB Port GUID and struct srpt_port directly following mainline v4.x target_core_fabric_configfs.c convertion for ib_srpt to work with rtslib/rtsadmin v2 code. These seperate patches can be found here: ib_srpt: Fix bug with chainged SGLs in srpt_map_sg_to_ib_sge http://www.risingtidesystems.com/git/?p=lio-core-2.6.git;a=commitdiff;h=ea485147563b6555a97dbf811825fbb586519252 ib_srpt: Convert se_wwn endpoint reference to struct srpt_port->port_wwn http://www.risingtidesystems.com/git/?p=lio-core-2.6.git;a=commitdiff;h=4e544a210acb227df1bb4ca5086e65bdf4e648ea This also includes the following recent v1 -> v2 review changes: ib_srpt: Fix potential out-of-bounds array access ib_srpt: Avoid failed multipart RDMA transfers ib_srpt: Fix srpt_alloc_fabric_acl failure case return value ib_srpt: Update comments to reference $driver/$port layout ib_srpt: Fix sport->port_guid formatting code ib_srpt: Remove legacy use_port_guid_in_session_name module parameter ib_srpt: Convert srp_max_rdma_size into per port configfs attribute ib_srpt: Convert srp_max_rsp_size into per port configfs attribute ib_srpt: Convert srpt_sq_size into per port configfs attribute and v2 -> v3 review changes: ib_srpt: Fix possible race with srp_sq_size in srpt_create_ch_ib ib_srpt: Fix possible race with srp_max_rsp_size in srpt_release_channel_work ib_srpt: Fix up MAX_SRPT_RDMA_SIZE define ib_srpt: Make srpt_map_sg_to_ib_sge() failure case return -EAGAIN ib_srpt: Convert port_guid to use subnet_prefix + interface_id formatting ib_srpt: Make srpt_check_stop_free return kref_put status ib_srpt: Make compilation with BUG=n proceed` ib_srpt: Use new target_core_fabric.h include ib_srpt: Check hex2bin() return code to silence build warning Cc: Bart Van Assche <bvanassche@acm.org> Cc: Roland Dreier <roland@purestorage.com> Cc: Christoph Hellwig <hch@lst.de> Cc: Vu Pham <vu@mellanox.com> Cc: David Dillow <dillowda@ornl.gov> Signed-off-by: Nicholas A.

Support for the SCSI RDMA Protocol (SRP) Target driver. The
|
|
SRP protocol is a protocol that allows an initiator to access
|
|
a block storage device on another host (target) over a network
|
|
that supports the RDMA protocol. Currently the RDMA protocol is
|
|
supported by InfiniBand and by iWarp network hardware. More
|
|
information about the SRP protocol can be found on the website
|
|
of the INCITS T10 technical committee (http://www.t10.org/).
