I have written a Linux kernel module (in Linux 2.4, Red Hat 9) which does the followings:

It takes srcIP, sourceport, destIP, destport and loadvalue as command line arguments. If configured load value is greater than 1, it creates different channels (i.e. No of UDP channels created equals to configured load value), assign different source port and destination port to different channels and send UDP datagram in different channels. Say for example the configured parameters are as follows srcIP=10.17.17.43 destIP= 10.17.17.44 sourceport=10000 destport= 20000 loadvalue=2. Then it creates two UDP different channels and transmits UDP packets (in every 20 milliseconds) to destination IP address (i.e., 10.17.17.44) with source port 10000, destination port 20000 in one channel and source port 10002, destination port 20000 in another channel.

When I configure to pass ?loadvalue=500? and run the module, I get the below kernel panic message in system log file (i.e., var/log/messages)



Running the same linux kernel module ,in 1000 loadvalue, I get this message, in text console.

What are the root cause of these problems and how will I solve these ?

Since you don't post any of your code, and you've written it for a VERY old kernel and version of Linux, there's not much for us to go on.

Since you wrote the code, you're the best one to debug it. Not sure what the point is, though, since even if you get it working right, it'll be useless for any modern distro, with a 2.6.xx kernel.

Kernel Panic Messages:

Ok...is there some point/question to that post??? We get that you're having kernel panic messages. Did you read my first post? About the very old system you're running on? About how you haven't posted any of your code, or given us any details about it??

Without information, we can't help. And again, YOU wrote this code....YOU are the best person to debug it.

No Guruji ,actually this is a task given by my boss to me ..

In your first post, you said you wrote it:
Who is "Guruji" ??

LOL

She must be referring to TB0ne as he is titled "Guru" and "ji" is a mark of respect in Hindi.

She?

Obviously, you recognize the name. Which part of the screen name is the feminine name that you are seeing?

"divyashree" This whole word is a girl's name in India !

I am reasonably clueless about Indian culture and language. Really hope to visit someday.....

I can imagine how much difficult it is for you to pronounce that name *properly*

But in fact it is a very sweet name pronounced as follows:
div--ya--sh--ree

And you must be thinking anishakaul is a weird screen name.
But in fact anisha is my actual first name and kaul is my actual last name.

You are most welcome here
and you must visit South India. Southern India has still a lot of culture preserved.

Ok...then how about this: WHOEVER wrote the code, is the person responsible for debugging it. If your boss gave you the code to debug, then it is YOUR responsibility to do it. You have the source code, there's not much more help anyone can give you.

No No ,that's not the case . The code is not given but the question is asked to find what may the possible cause of that and the solution ...

Ya Anisha you r right ,I referred to Tbone as Guruji

You are mostly welcome sir .
