Compiling Linux kernel "correctly"

http://serverfault.com – Recently I have come across a security module for the Linux kernel called Linux-VServer which allows you to virtualize many things and "partition" the OS to reduce the effects of a compromise. I was surprised to see that it required a re-compilation of the kernel as most of these types of things are simply modules that can be loaded at run time (selinux, apparmor). My problem with recompiling the kernel to enable Linux-VServer is I am a beginner when it comes to compiling my own kernel. I use the Ubuntu package repositories to update my kernel which gives me the peace of mind that whoever com (HowTos)

Stories similar to Compiling Linux kernel "correctly"

I was wondering if it was possible to retrieve a copy of the Linux kernel with vServer embedded into it already rather than recompiling it by using apt-get. I have followed the documentation on their website here that shows you how to add their package repository to apt-get and then install it via apt-get install linux-image-vserver.

My last kernel development was in version 2.6~ Now I try to compile a module, and I get the following error when compiling outside the kernel tree.

/bin/sh: 1: /home/blabla/workspace/kernel35/linux-3.5/scripts/recordmcount: not found

The object file is created properly, however the problem is within the kernel Makefile itself, something has changed and I wasn't updated ?

I'm using vanilla kern

I have recently compiled linux kernel 3.2. But at time of compiling in make menuconfig, I had disabled sound support.

Now, I want to enable it without recompile it. I don't want to use stock kernel or direct kernel image, I always wanted to use compiled kernel.

How can I get pcf8574 back? 1 year 21 weeks ago

I have recently upgraded my server from Debian 5 (Lenny) to 6 (Squeeze), and I noticed that the new kernel 2.6.32 don't have module named pcf8574, neither pcf857x.

I need it for my application, and I don't know how to get it back.

I have no experience in building kernel modules, neither compiling whole kernel.

Linux 2.6.32-5-686 #1 SMP i686

Anyone know why it's not there anymore?

My guess is

Compiling 3.2.7 1 year 16 weeks ago

After months writing code and seeing multiple failures I have given up writing a kernel and decided to use the linux kernel. My only problem is that I'm not sure how.

I have looked up how to compile the kernel but it just isnt working. I downloaded 3.2.7 from kernel.org and I have an Ubuntu computer. What am I supposed to do to get the kernel from files to a bootable ISO image?

Im running VM for the first time. I get the following message:

Quote:

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing

'/etc/init.d/vboxdrv setup'

I want to cross compile an ARM kernel module on my x86 ubuntu linux. I have downloded kernel source(linux 2.6.26 since target ARM machine is running this linux version). and I apt-get'ed arm cross compiler.

I found a good tutorial on how to install Linux Kernel 3.0 on Ubuntu 11.04 Natty Narwhal on Softpedia website. Linux Kernel 3.0 brings many improvements. You can download the deb package for Linux Kernel 3 headers and Linux Kernel images as well so its easier for Ubuntu users to upgrade to Linux Kernel 3.0 [...]
