Journey of a network packet through linux 2.6 network stack

Journey of a network packet through linux 2.6 network stack

[AFT]

Hi,

A document with this heading can be found for 2.4 network stack. But i
have not found any document regarding 2.6 network stack.

When i was searching netfilter mailing list archive, i got the following
post :

http://lists.netfilter.org/pipermail/netfilter/2007-august/069583.html

in this post author mentioned about a document named after this. but
does not gave any link to that document.

so i'm wondering if any similar document can be found?

cheers.

Its because of a accidental "C-x C-u' followed by "C-x C-l" to fix it.

http://en.wikipedia.org/wiki/Netfilter
http://en.wikipedia.org/wiki/iptables

(And to answer the other two questions of Karim Sattar: 2. the code 
between kernel and user interface are obviously different, 3. iptables 
is not a daemon.)

And if you actually did a Google search, you would have found a copy of 
it, cached by Baidu on two seaprate pages.

http://hi.baidu.com/john_len_dead_dance/blog/item/b85af87289b9e2128601b051.html

It even mentions its source file:

I've done the google search actually. But i got put off by
"baidu". anything chineese gets me to press X button. I didn't think i
will get a valuable life lesson in kernewbies. Next time i will give
chineese a chance. :)

I have found out some more comprehensive document than this. I will post
those link for anyone who is also searching archives for the same
documents.

You've got Linux Networking internals.

It's pretty think, but it provides some panoramic. As kernel code
evolves quite quickly, you may find that some things have changed, but
it's a good base to start with if you're looking for an alternative to
reading pure code.

Hi Pablo,

I have a scanned pdf of Linux kernel internals. But i stopped reading
when i found out struct sk_buff does not have a member struct
sk_buff_head * list like the book mentioned. It turns out its removed in
2.6.14/15 series where the book references a earlier code. 

On the plus side this made me set up cscope in my emacs. So i guess i
should thank the book for this.

Cheers.
