RE: Basic question on debian kernel versions
Ben, I would like give next set of patches for updating the be2net driver. I still have problem is accessing the debian's source tree. I do have the linux 3.2 source package which has my last patches applied to it. Can I port the patches from net-next tree against this source package? Also, what should be values for Package and version when I open a bug for this?

Start with the current version in unstable (3.2.35-2), use 'dch' to add a new changelog entry, use 'quilt' to add your patches, then send either: - a debdiff between 3.2.35-2 and your new package (see the manual page for debdiff) - a tarball containing the added patches and new series file However, all changes must be justifiable as important bug fixes or support for new hardware. New features, cleanup, minor bug fixes etc. are not allowed, except if you need them as dependencies of the important changes.

RE: Basic question on debian kernel versions
Hi, I have tried installing different version of debain kernels from CDs in the archive. For ex: I tried Debian 6.0.0, 6.0.3, 6.0.4. After installation all installations show /etc/debian_version as 6.0.4 and the same output for uname -r (2.6.32-5-686). How does one differentiate which version of debian kernel is installed? If all the version of debian installation have same value for uname -a, then will driver compiled for 6.0.0, load on 6.0.3 as is? I am sure I am missing something basic here. Thanks, Sarvesh

All updates to the kernel are checked for binary incompatibilities. If it's possible to maintain compatibility it's done. Otherwise the abi version (the 5 in 2.6.32-5-686) is bumped and then you need to recompile your external modules.

RE: Basic question on debian kernel versions
Then, give that 6.0.0, 6.03 and 6.0.4, since uname -a output is the same, can I assume that kernel image is the same and building driver for any of these debian version will give me the same driver binary? -Original Message- From: Uwe Kleine-König [mailto:u.kleine-koe...@pengutronix.de] Sent: Wednesday, April 18, 2012 12:45 PM To: Bandi,Sarveshwar Cc: debian-kernel@lists.debian.org Subject: Re: Basic question on debian kernel versions On Tue, Apr 17, 2012 at 11:56:00PM -0700, sarveshwar.ba...@emulex.com wrote: Hi, I have tried installing different version of debain kernels from CDs in the archive.

RE: Basic question on debian kernel versions
I installed linux headers in both my installations (one of which I installed using 6.0.0 cd and other using 6.0.4 cd) using apt-get install and dpkg --list shows same output on both the systems: root@debian:~# dpkg --list |grep headers ii linux-headers-2.6.32-5-686 2.6.32-41squeeze2 Header files for Linux 2.6.32-5-686 ii linux-headers-2.6.32-5-common2.6.32-41squeeze2 Common header files for Linux 2.6.32-5 When I build driver against the two versions the modinfo output is identical. So I am back to the question: How do I know which driver was built for which version of debian? And even more basic question, how do I know which version of kernel I am running now?

RE: Basic question on debian kernel versions
Well. I have tried everything possible to avoid updates. But no matter which CD I install from I always land up in same version of kernel (6.0.4). The alternate way is for me to get linux-kernel source package for the version I need to use and re-compile the kernel and build the driver against it. But what is the best way to know the which is kernel source package for given version of debian?

'6.0.4' is the distribution version, but presumably you also get the latest kernel package version from stable-security. The alternate way is for me to get linux-kernel source package for the version I need to use and re-compile the kernel and build the driver against it. You can download and install old versions of packages from http://snapshot.debian.org. But what is the best way to know the which is kernel source package for given version of debian? Package updates in point releases are listed in a changelog for the release, e.g. http://ftp.debian.org/debian/dists/squeeze/ChangeLog. You can work out the original package version for a release by looking down the changelog for the current package in stable to the newest entry for which the distribution is 'unstable' or 'testing'. The result is version 2.6.32-30. All this said, I don't encourage you to make extra effort to support older point releases. Debian users are expected to install updates from each point release and from the security archive, and as you've seen those are normally installed automatically even if you start an installation from disc. Also, I would really appreciate it if you could help us to provide updated drivers for Emulex hardware in stable updates, so that Debian users don't need to download and install them separately. These would have to be based on changes that are already in mainline Linux.
