THIS CODE IS NOT LONGER MAINTAINED, SINCE THE SOFTIWARP DRIVER BECAME PART OF UPSTREAM LINUX WITH KERNEL 5.2, AND IS MAINTAINED THERE.
Please use the latest SoftiWarp driver and its user RDMA library from your Linux distro for running software RDMA over IP interfaces. We keep this zrlio siw repo only for reference.
SoftiWARP (siw) is a software iWARP kernel driver and user library
for Linux. It implements the iWARP protocol suite (MPA/DDP/RDMAP,
IETF-RFC 5044/5041/5040) completely in software, without requiring
any dedicated RDMA hardware. It comprises a loadable Linux kernel
module siw located in kernel/ and a user level library libsiw
located in userlib/.
SoftiWarp targets for integration with the OpenFabrics (OFA) ecosystem. For OFA integration, it is written against its kernel and user level interfaces.
SoftiWARP supports both user level and kernel level applications. It makes use of the OFA connection manager to set up connections. The kernel component runs on top of TCP kernel sockets.

userlib/: user library
common/: common include file(s)SoftiWARP code tries to stay up to date with recent Linux kernels.
Git master is supposed to run on the newest stable kernel.
To ease code maintenance and to allow for back porting
of any new features, old versions of SoftiWARP will be branched
off with discriptive names. master is always tagged with the kernel
version it matches.
Re-installing a newer SoftiWARP version after a kernel upgrade shall include making and re-installing both user library and kernel module (see below).
