kernel patch

[LDC]

hi

I downloaed latest 2.6.25 patch, but I don't know how to patch it under Fedora (the "Linux Guide" tutorial doesn't work, maybe there is a different directory management.
Anyone here did a tutorial?

[LDC]

aw, it would be useful to me even a small hint on how to patch the kernel ^^;;;

thanks

Try

thanks leigh

I have no "usr/src/linux" directory

instead I have

[root@solomon src]# ls
ati  kernels  redhat
[root@solomon src]#

maybe the author mean "linux" as "the name of your distro", which in this case would be "redhat", and so I would've put the patch there.
But is not clear enough to me, since it is not stated explictly anywhere.

how exciting, my first time..patching a linux kernel

Where did you extract the kernel source ?
Are you rebuilding a kernel srpm ?



/usr/src/linux is normally just a symlink to the kernel source .

I did extract it into /usr/src/

nope, I just wanna patch patch my .64 one into the stable final one...

as you've seen, there is nothing like that

no luck patching, so I tried "yum update kernel" as suggested in the Fedora Wiki... but it didn't work either -__- says that there is nothing to update (I know what you're thinking now: nope, I have not already the latest version... I have still the one in my signature)

"yum update kernel" and "yum upgrade kernel" doesn't work either ,saying

[root@solomon ~]# yum upgrade kernel
Setting up Upgrade Process
Could not find update match for kernel
No Packages marked for Update
[root@solomon ~]#

what should I do?

There is a good guide/tutorial in the "Guides & How-To Articles" section on this very forum on how to recompile a kernel, including adding patches, and building the finished product into rpm packages. You will need the rpmbuild-tools package, and maybe a few others, for this. I used this guide successfully on my system.

I will try this too, thanks

• Get the latest .srpm for the kernel you want.
• Create a directory (for example $HOME/rpmbuild) where to have the rpm build environment, copy the contents of /usr/src/redhat to that directory:
  

  mkdir rpmbuild
  cp -R /usr/src/redhat/* rpmbuild/

• Make an .rpmmacros file in your home directory and have something like this in it:
  

  %packager       [Your_name_here]
  
  %_topdir        [point_to_your_home_rpmbuild_dir]

• Install the .src.rpm package:
  

  rpm -ivh <package>.src.rpm

• Go into the SPECS directory and prepare the sources:
  

  cd rpmbuild/SPECS/
  rpmbuild -bp kernel.spec

• You should be able to patch the kernel in rpmbuild/BUILD/kernel

If you only want to patch a kernel for which you got the sources off kernel.org, you simply have to extract the .tar.bz2 package, and then go into its directory and than apply the patch:

tar jxf linux-2.6.25.tar.bz2
cd linux-2.6.25
patch -p1 -i /path/to/patch

If the patch is bzipped, you will need to extract it before applying. Or use pipes (which may be bit more "complicated")

wow, that's quite a nice tutorial
many thanks!
