Smile Compare-Kernel 2.4 V.S. 2.6 <Security>


Dear friends,

I want to know about the security differences between Kernel 2.4 and 2.6 specially I want to know what separates /proc. in this two versions?

Best Regards,
Eilya

This sounds a little bit like homework...

I have always understood that the 2.4.X kernels were about stability, not security. I would hope that the latest security enhancements would be in 2.6.X. And--there is always something like SELinux.

I don't understand. /proc is the collection of virtual files that show you what is happening in various memory structures. AFAIK, it has the same functionality in 2.4 and 2.6 kernels.

So is it true to say, we don't have any security changes in the new version?
And about /proc, I want to know if we have any change in the new version?

More than I can (or would want to) list has changed between the 2.4 and 2.6 series. The most obvious being the Linux Security Framework (or LSM) of which SE Linux is a user. Even within 2.6 structures are in a constant state of upheaval. Kind of shows: for instance Linux Kernel Modules (or LKM's) that worked with earlier versions of 2.6 likely won't work with current versions. Wrt /proc I'm not sure what you mean, but if you look at /proc entries for a single process for instance you'll see 2.6.n kernels carry much more information.

Like I hinted at in the other thread you should ask very specific questions and also tell us in detail what it is you are looking for. The way you ask for things right now is similar to asking somebody to count grains of sand in the Sahara and also describe each one in detail. Studying (the progress of) the kernel's source could be beneficial.

Here's two resources that might benefit you: Linux Kernel Newbies, KernelTrap.

A Google search for linux kernel internals should provide you with tons of additional resources.

You might also wanna invest in a book like this one, for example.

I have no opinion on which is the best kernel internals book - I'm not a kernel hacker. But if you read the reviews for that book I linked to on Amazon.com you'll see that people who've read it seem to think it's an awesome book.
