hello,
I am checking some conditions in packet after IP
header is removed and based on that want network stack
to discard skbuff so i add it in ip_input.c .
But it gives oops message that
Warning: kfree_skb passed an skb still on a list and
then prints oops

Hello,
I have written one /proc file creation kernel
module. This module creates /proc/file and defied
operations on it. Also i have written user program
that will read write to /proc files from user space.
Now what i want is to use same bufproc_read
bufproc_write functions defined in

I have one linked list data structure added to
a file in kernel source code which has some kernel
info. I want to acess that linked list structure from
user space. Is that possible??
Also how to add own system call usable at user

While browsing linux source code what i found
that if function is defined as

flags, int mode)
then its not exported to kenrel and thus not seen in

defined with asmlinkage then it

1) I want to know how much can i write to

size???
2)Also how can i call /proc entry files

and how? Say i have read

I have some questions...
1)When data is copied to ICMP/UDP packets?
when i trace kernel code in 2.4.26 kernel version is
that in case of ICMP and UDP packets the packet gets

ip header is built.
2) What getfrag does? Does it

Can anybody explain me how ethernet header is
added to every packet outgoing? I check eth.c file and
found eth_header that is used for adding ethernet
header on skbuff packet. But does each packet calls
this function? I think not as theres a cache header
function used that cache

I am knowing all 2.4 kernel network stack

instead thers a new function that is
ip_append_data. What i want to
