|
|
<P>For debugging purpose, and eventually stack internals learning purpose, we have develop
|
|
|
|
|
an userland stack version, sharing most of the <A href="stack.html">network stack</A>
|
|
|
|
|
source code but hosted by a app, <i>net_stack_tester</i>, in contrast with the real one hosted in kernelland, behind the
|
|
|
|
|
<A href="stack_driver.html">stack driver</A>.
|
|
|
|
|
</P>
|
|
|
|
|
|
|
|
|
|
<P>The following image shows this debug platform overall design:</P>

|
|
|
|
|
|
|
|
<P>The <A href="libs.html#libnet">libnet.so</A> library was modified to check if the NET_STACK_DRIVER_PATH
|
|
|
|
|
environment variable is defined and use his value as driver path to interface with.
|
|
|
|
|
To switch to <i>net_stack_tester</i> hosted stack version, just run this
|
|
|
|
|
from a Terminal:</P>
|
|
|
|
|
|
|
|

<p>

<TR><TD><TT>$ export NET_STACK_DRIVER_PATH=/dev/net/server</TT>
|
|
|
|
|
</TABLE>
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<P>Starting from there, all apps using libnet.so services will use the debug stack version.
