    Subjectuser space web server accelerator support
    Hi,

    I've been working for a while on a user-space web server accelerator (as
    opposed to a kernel space accelerator, like TUX). So far I've had very
    promising results and I can achieve performance (spec) figures
    comparable to those of TUX.

    Although my implementation is entirely sitting in user space, I need
    some cooperation form the kernel for efficiently forwarding network
    connections from the accelerator to the full-fledged Apache server.

    I've made a little kernel hack (mostly lifted out of the TUX and khttpd
    code) to forward a live socket connection from an application to
    another. I'd like to clean this up such that my users don't have to mock
    with their kernel to get my accelerator to work.

    Would it be a major heresy to ask for a new system call?

    If so I could still hide my stuff in a kernel module and snatch an
    unused kernel call for my private use (such as the one allotted for
    tux). The problem with this is that the kernel only exposes the "right"
    symbols to the modules if either khttp or ipv6 are compiled as modules.

    How could this be fixed?

    TIA, ciao,

    - Fabio
