ip_send() function

ip_send() function

[Markus Zeilinger]

Dear all,

I am currently writing a paper for my studies about netfilter and Linux
Firewalling. In this case I also write a chapter about packet handling
through the Linux network stack.
Several papers and also in Harald Welte's "The journey of a packet through
the linux 2.4 network stack" mention a function ip_send() in the process of
packet forwarding. According to Harald this function is defined in
/include/net/ip.h. But I cannot find a definition there, and surprisingly I
was not able to find the ip_send() function anywhere in the kernel source. I
searched through Kernel 2.6.6, 2.4.6 and 2.4.0 but did not find any tracks
of a ip_send() function!?!

Can you help me with this problem? Sorry if this is a stupid question, but I
am a newbie in Linux networking. ;-)

Thx a lot for your assistence!

best regards,
Markus

  http://lxr.linux.no/source/include/net/ip.h#L162

  Use LXR, it can help a lot!

Hi Markus,

  Maybe you didnt look properly, you can find ip_send() at the given path
/usr/src/linux.x.x/include/net/ip.h
Its defined there as a static inline function returning int.
