Subject: [PATCH v6 00/25] RTRS (former IBTRS) rdma transport library and RNBD (former IBNBD) rdma network block device
Date: Mon, 30 Dec 2019 11:29:17 +0100
Message-ID: <20191230102942.18395-1-jinpuwang@gmail.com> (raw)

Hi all,

here is V6 of the RTRS (former IBTRS) rdma transport library and the
corresponding RNBD (former IBNBD) rdma network block device.

Changelog since v5:
1 rebased to linux-5.5-rc4
2 fix typo in my email address in first patch
3 cleanup copyright as suggested by Leon Romanovsky
4 remove 2 redudant kobject_del in error path as suggested by Leon Romanovsky
5 add MAINTAINERS entries in alphabetical order as Gal Pressman suggested


Introduction
-------------

RTRS (RDMA Transport) is a reliable high speed transport library
which allows for establishing connection between client and server
machines via RDMA. It is based on RDMA-CM, so expect also to support RoCE
and iWARP, but we mainly tested in IB environment. It is optimized to
transfer (read/write) IO blocks in the sense that it follows the BIO
semantics of providing the possibility to either write data from a
scatter-gather list to the remote side or to request ("read") data
transfer from the remote side into a given set of buffers.

RTRS is multipath capable and provides I/O fail-over and load-balancing
functionality, i.e. in RTRS terminology, an RTRS path is a set of RDMA
connections and particular path is selected according to the load-balancing policy.
It can be used for other components not bind to RNBD.

RNBD (InfiniBand Network Block Device) is a pair of kernel modules
(client and server) that allow for remote access of a block device on
the server over RTRS protocol. After being mapped, the remote block
devices can be accessed on the client side as local block devices.
Internally RNBD uses RTRS as an RDMA transport library.
