Hi All, I was wondering if someone could lend me a hand on applying the "SKAS" patch to my kernel? I've searched the internet, and as I've never compiled a kernel before, I don't want to risk breaking my system. Is currently is hosting users with cPanel on it (if that makes any difference). My current kernel is "2.6.9-55.0.6.ELsmp #1 SMP" (CentOS 4) which I keep tidy with "yum update" so I've never "patched" it myself, but I'm not sure if Yum has. I therefore don't have a kernel tree (etc.) to add the Arch what's not to. I would appreciate anything that would point me in the right direction. For example, a recommendation to "compile" my own working kernel first, then patch it? Any advice would be greatly greatly appreciated. Many Thanks In Advance, Jay |

Hello Jay patches are always applied to sources. Once you've patched them, you can compile. First of all you need "bzcat" program on your Linux distribution and Linux kernel sources in your /usr/src directory. Go to your kernel root directory, (e.g. /usr/src/linux , where linux is a symbolic link to your current kernel source directory) and patch the sources. Practically you have to do that: 1) cd /usr/src/linux 2) move your skas-2.6.20-v9-pre9.patch.bz2 file in /usr/src/linux directory you will do something like this: mv /home/myHome/skas-2.6.20-v9-pre9.patch.bz2 . (the dot indicates the current directory, that is /usr/src/linux). 3) bzcat skas-2.6.20-v9-pre9.patch.bz2 | patch -p1 --dry-run if no errors appear, repeat 3 again without --dry-run option. 4) bzcat skas-2.6.20-v9-pre9.patch.bz2 | patch -p1 5) You've done. Now compile your kernel as you like. (compiling the kernel is not simple, if it's the first time.

He's looking for a more "official" way to compile it, like, against RHEL5/CentOS5 sources and probably even put it into an RPM so the system will handle it correctly. I don't know how to do this myself since with CentOS/RHEL I've always just let the system handle the kernel. (one of the reasons I even run it) --Dan On 10/6/07, Flavio <fbc...@gm...> wrote: > Hello Jay > > patches are always applied to sources.

Hi Flavio, Many Thanks for your response. I have attempted to compile a kernel, using your patching instructions, but when the datacenter attempted to boot it, they said the following error happened: mkroot dev: label / not found Mounting root filesystem mount: error 2 mounting ext3 mount: error 2 mounting none switching to new root switchroot: mount failed: 22 umount /initrd/dev failed: 2 kernel panic - not syncing: Attempted to kill init! Any ideas as to it's resolution? Many Thanks to you, and all that have replied. Jay On 07/10/2007, Flavio <fbc...@gm...> wrote: > Hello Jay > > patches are always applied to sources.

This should help out quite a bit, I just dug it up: http://www.howtoforge.com/kernel_compilation_centos It shows you how to create a kernel for centos, starting with vanilla (official kernel.org) sources. You can patch that tree before compiling. HTH, Dan On 10/8/07, Jay Shah <jay...@gm...> wrote: > Hi Flavio, > > Many Thanks for your response.

Note that for x86_64 architectures skas3 patch doesn't work. (See info about skas0 mode) Excuse me but in my previous e-mail I gave you not the right URL. It was about guest kernel patching. Anyway.. kernel patches are all applicable in that way. > using your patching instructions, but when the datacenter attempted to > boot it, they said the following error happened: > > mkroot dev: label / not found > Mounting root filesystem > mount: error 2 mounting ext3 > mount: error 2 mounting none > switching to new root > switchroot: mount failed: 22 > umount /initrd/dev failed: 2 > kernel panic - not syncing: Attempted to kill init! I don't think skas3 patch may cause this kind of problems. It seems there are some other trouble in filesystem support in the guest kernel. But, excuse me, only to make me understand... If I did understand correctly you 1) applied SKAS3 patch to your Linux HOST kernel (the real kernel, that one you always boot when you power on your PC) 2) applied uml patch to your uml sources (did you?) 3) tried to boot a kernel. Here I didn't understand if you tried to boot the host or the guest kernel. Error messages you wrote before, seems to be coming from the uml kernel boot. In that case, try to setup /etc/fstab correctly in your UML filesystem. That kind of problems may also be caused by a wrong kernel compilation, e.g. you didn't include ext3 filesystem support as built in.

SKAS0, is that secure, i.e. is it "breakable"? You shouldn't choose SKAS0 mode if your architecture supports the SKAS3 one. Anyway, it's not properly a choice, but now, it doesn't matter. If you don't notice any problem loading skas3 mode, get rid of skas0. > Yes, I applied it to the host kernel, which is why I asked my > datacenter to reboot the server. OK... Did you compiled your kernel in its defconfig? Is it your first time you compile a Linux kernel?? > No, I haven't touched the UML sources as-of-yet.

Mmh... I guess you never compiled a Linux kernel... If your host filesystem is ext3, you absolutely need ext3 support built in in the host kernel. Without it you cannot boot Linux. The only way to boot without that support is to provide an initrd image. > > Many Thanks Again, > > Jay > You're welcome, Flavio |

So, what you have to do is (starting from the beginning): 1) cd /usr/src/linux (where linux point to /usr/src/linux-`uname -r`) 2) cp /boot/config-`uname -r` .config 3) make menuconfig 4) you configure your kernel here.. ;-) Here you decide if you want to use an initrd image or not.

Once you've done, exit from kernel configuration and 5) make && make modules_install 6) cp arch/i386/boot/bzImage /boot/kernel-`uname -r`-skas3 7) cp .config /boot/config-`uname -r`-skas3 8) cp System.map /boot/System--`uname -r`-skas3.map 9) cd /boot && ln -s System--`uname -r`-skas3.map System.map 10) update your bootloader 11) reboot > Apologies, I get it now.

I don't know, but I guess that if you use an initrd image, ext3 may be not included. Check it!!! Flavio |

If you get an error such as that, it means you need to include it as either a module, or compile it into the kernel. It's not a problem with the doc, just a misconfiguration at config time.

Mmhh.. Hello, this is not an UML issue. I think you should search on google Linux before. You can find a lot of stuff about Error 15 from grub. For example, have a look here: http://www.linuxquestions.org/questions/fedora-35/grub-error-15-431469/ (I found it using google) That kind of errors are not related to UML. Anyway, try to comment the "savedefault fallback" line, first of all. In my opinion it is not needed. I think that error cames from a mistake in your grub.conf. Check you entered the kernel line correctly. It maight be that you made a mistake writing root(hd0,0). If grub doesn't find the kernel file in that partition, it may print the error 15. Make also sure the kernel file is in /dev/sda3. It's not so simple to configure GRUB, if it's the first time, but nothing impossible. Search through the Internet how to configure Grub.

Hi Flaivo, Your instuctions have worked properly, and ULM now boots is into SKAS3 mode, and the kernel is perfect!!! Many Many Thanks, Jay SHah |

You're welcome. Woow! I'm really happy for you! Enjoy UML! Which distribution did you choose for UML guest system?

Hi, I am using CentOS 4 for the host machine, and CentOS 5 for the UML Guest. I am using kernel 2.6.20.20-skas3-v9-pre9. Jay |

Just for my curiosity, how did you get your UML guest filesystem? I know there are a lot of ready to use filesystem images for example here: http://uml.nagafix.co.uk/ I guess you got it there. Isn't it? In my case I chosen to make my UML filesystem by myself. I prefer to have a Gentoo host filesystem containing a virtual Debian UML-based. In order to get UML filesystem I used debootstrap utility. Further information at: http://www.vdd-project.org/index.php?option=com_content&task=view&id=20&Itemid=51#A%20Debian%20root%20filesystem Bye, Flavio On 12/10/2007, Jay Shah <jay...@gm...> wrote: > Hi, > > I am using CentOS 4 for the host machine, and CentOS 5 for the UML > Guest.

Ok, in any case you made the best choice I guess. Don't worry about it. Installing Debian in that way seems to be most difficult than it is. If you follow the instructions you will be able to enjoy UML Debian too very quickly!!! On 12/10/2007, Jay Shah <jay...@gm...> wrote: > Hi Flavio, > > That's a bit beyond me.
