BSD-style socket API in kernel space for TCP/IP networking. Original ksocket for v2.6 was published at http://ksocket.sourceforge.net/. This repository contains changes to make it compatible with new kernel versions. The ksocket API has been updated to incorporate the changes related to the iov_iter interface introduced in kernel v3.19+.

$ git clone https://github.com/hbagdi/ksocket.git
$ cd ksocket/src
$ make # make sure you have the kernel headers/tree installed
$ sudo insmod ksocket.ko
#now you can use the exported symbols from this kernel module

Look at sample sub-directory for code-samples.

$ cd ksocket/sample/tcp/
$ make
# two kernel modules are ksocket_tcp_cli_demo.ko(TCP client) and ksocket_tcp_srv_demo.ko(TCP server)
$ sudo ksocket_tcp_srv_demo.ko
$ sudo ksocket_tcp_cli_demo.ko
$ dmesg

The original ksocket work was to support Linux 2.6, however support for v5.4.0 has been included.

v5.4.0 support is a work on Linux ubuntu 5.4.0-66 x86-64, therefore there is no guarantee it works well on versions > 2.6 && < 5.3.x

In order to keep the 2.6 version stable it was left without the 5.4.0 work, instead we now have two branches: v2.6 (master) and v5.4.0
