[SOLVED] Network connection at kernel level

Yaphet · 05-20-2012, 07:13 AM

Hey, folks,

I have no resemblance of experience with kernel,
but I can cope with the references you may give.

I need to open a network connection between two
computers -- send and receive files --, but I've
got to do it within a kernel module.

I want to write -- or change, for my needs -- a
kernel module that sends and receives files from
a computer to another.

The interface would be built by system calls; they'd
reference the methods written in the kernel module,
passing file paths, or descriptors, as parameters.

The choice between paths and descriptors is merely
an implementation decision, and the easiest to be
treated at kernel level will be definitely chosen.

There's no concern about security issues here, as
this is only experimental; the configuration for
the network connection shall be as simple as
possible -- just send and receive files.

Hope you got my point, and have a solution for it.

Best,
Rubens.

Famous last words...

There are valid reasons why some things are and some things are not implemented at the kernel level. The most basic reasoning for not implementing something at the kernel level can be found in any discussion about making the kernel read something as opposed to the safe practice of writing like for instance the userland 'iptables' binary does when it comes to managing Netfilter.
As for the kernel server part kernel version 2.6 did have an in-kernel HTTP daemon for a while. Check the source?
