Android Network Stack newbie

[Peter]

Hi, I'm trying to learn about the network code under the android kernel for a project involving manipulating packets for security reasons. I have not dabbled in the unix kernel before so I don't have a good idea of where to start. I'm trying to find information about where certain protocols are located and I don't find much detailed information. Most of the information talks about bits and pieces in the linux kernel. But not even a whole image of the linux kernel network stack and then having to find the changes between the two. So I wanted to know if anyone on this board had any good information/tutorials on the android network stack or the linux kernel's? I've done a fair amount of digging via internet resources to no avail. Any help is appreciated. Thanks.

Much of the Android networking stack will be based on the linux
network stack. Googling for "linux network stack" should provide some
starting points. There's an oriley book on the linux kernel
networking stack (available for free online), but it's fairly dated..
So this question isn't really that Android related, the specific parts
of the network stack as it appeals to Android are things like the RIL
(well, okay, that's not really network so much, telephony, but still
worth reading about? Maybe not..) and frameworks (a la apache
harmony), but the actual implementation is on top of linux...

Hi,

Under <kernel-src-root>/Documentation/networking/  you may find interesting information. If you lack backgrounds maybe a book dealing with linux kernel is a good start or at least can be useful.
