cannot generate .ko file on my linux, although it can generate module.symvers.
But when I copy .c file and Makefile to another linux computer, there's no problem.
The strange thing is: make is successfuly executed, and returned 0;
system: RHEL5

Hi Everyone!
How can we make a socket() system call from a linux module executing in kernel space?
If any one knows, kindly tell me. It will be great.
I want to use the socket interface in linux kernel space for sending raw packets over the network.

Hi All,
Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff.
Cheers,

Hi,
Does anyone know if it is possible to know the current value of a kernel module parameters after the module is loaded. Are the values of the parameters advertised at some /proc or /sys location ?
The only thing I know is modinfo, that actually looks a the module .ko and gives a... (3 Replies)
Hi all,
I am working on USB data monitoring on Fedora Core 9. Kernel 2.6.25 has a built-in module (the one that isn't loadable, but compiles and links statically with the kernel during compilation) to snoop USB data. It is in <kernel_source_code>/drivers/usb/mon/.
I need to know if I can... (0 Replies)
Hi All,
I need to develop a kernel module which changes the IP address of a package according to its mac address. It would be a sort of L2 Nat.
Somebody know if I can do this using netfilter??
Thanks. (2 Replies)
Question may seem illogical but I still need clarification.
Can we debug kernel modules loaded on my target system using kdb / kgdb without using any other system or remote debugging?
In other words my question is can we use kdb/kgdb to debug kernel modules running on same system? (2 Replies)
Hi all!
I am trying to register a device in an existing device class, but I am
having trouble getting the pointer to an existing class.
I can create a class in a module, get the pointer to it and then use
it to register the device with:

Hi everyone,

Here's what I've tried so far:

ctrlaltdel
CTRLALTDEL(8) Linux Programmer's Manual CTRLALTDEL(8)NAME
ctrlaltdel - set the function of the Ctrl-Alt-Del combination
SYNOPSIS
ctrlaltdel hard|soft
DESCRIPTION
Based on examination of the linux/kernel/sys.c code, it is clear that there are two supported functions that the Ctrl-Alt-Del sequence can
perform: a hard reset, which immediately reboots the computer without calling sync(2) and without any other preparation; and a soft reset,
which sends the SIGINT (interrupt) signal to the init process (this is always the process with PID 1). If this option is used, the init(8)
program must support this feature. Since there are now several init(8) programs in the Linux community, please consult the documentation
for the version that you are currently using.
ctrlaltdel is usually used in the /etc/rc.local file.
