Programming :: Convert Urb To Skbuff?
Nov 30, 2010
I am trying to write a kernel module which is the combination of the usb driver and a network driver, now whenever the data is recieved by the usb driver it will be in struct urb, but the data that is required by the net driver is sk_buff, now how do i convert a urb to sk_buff, i found something similar is being done in the phonet protocol, but i couldnt understand, howexactly this is being done. Can someone explain this code.
drivers/net/usb/cdc-phonet.c
Code:
static void rx_complete(struct urb *req)
{
struct net_device *dev = req->context;
struct usbpn_dev *pnd = netdev_priv(dev);
[Code]....

Why can not use skb_queue of skbuff to enqueue and dequeue within qdisc in kernel programming? Also, I cannot find the source code of *enqueue of qdisc in LXR. Anyone understands qdisc and skbuff in kernel well?

i am writing a netfilter module for linux 2.6.34.6-47 / 2.6.35. while i could capture the packets on the incoming hook since the same came as a single packet in probably the allocated skbuff area by the stack, i found that packets going out of the machine are getting splitted into linear and non-linear area. skb->data gives the total length of packet as correct, but when i extract skb-> data to print it, it prints only ip and tcp header. Now to treat the data i need to extract it and then push it back on the route.
To clarify if my data is 3 bytes . the total length by passing pointers show as 55 bytes = ( 52 byte of header + 3 byte of data), but i can't access these 3 bytes by using skb->tail - skb->data. how to extract outgoing data for any further action and then put it back on route for further encapsulation by the L2 stack or whatever. will skb_linearize() or skb_linearize_cow() be of any use , if yes how and why?

I have an existing line of code from a P2 script that I cannot find a solution to converting to P3:
Code:
for i, x in map(None, list1, list2):
I have found the information about converting the simple case:
map(None,x) becomes list(x)
But my googling was unable to find a solution when more than one iterable exists.

I'm learning C and trying to write a program to convert gigabyte into byte. It will take 50% of the value given and then convert that value into byte. But the problem is the output goes into minus / negative value. Like, if I enter 22, I get output: -2147483648.
Code:
#include <stdio.h>
#include <math.h>
main (int argc, char* argv[])

I wrote a bash script a few months ago and now I want to convert it to a C program. However, i used awk a lot in my script, and I don't know what to use in place of awk. The awk calls are simple, like string splitting and math, but I don't know of any replacement for the string splitting function. Are there any C libraries that include some sort of string splitting function?

I bet this is a Perl one-liner (or very simple python script).I have a tab separated files in which each row looks like:Unique_Eight_Character_Sequence [3 tabs] data1~moredata1~moredata1 [3 tabs] data2~ moredata2~ moredata2 ... dataN~.The output file should have each column converted into a row (with the unique character sequence copied in for the first column), and then each "~" replaced by a comma.

Currently I have this code:
