Linux Kernel v2.6.23 Released

diegocgteleline.es writes "After 3 months, Linus has released Linux 2.6.23. This version includes the new and shiny CFS process scheduler, a simpler read-ahead mechanism, the lguest 'Linux-on-Linux' paravirtualization hypervisor, XEN guest support, KVM smp guest support, and variable process argument length. SLUB is now the default slab allocator, there's SELinux protection for exploiting null dereferences using mmap, XFS and ext4 improvements, PPP over L2TP support. Also the 'lumpy' reclaim algorithm, a userspace driver framework, the O_CLOEXEC file descriptor flag, splice improvements, a new fallocate() syscall, lock statistics, support for multiqueue network devices, various new drivers, and many other minor features and fixes. See the changelog for details."

You know the drill...

[SnoopJeDi]

overlord. welcome. yay.

On a more serious note, are these improvements dramatic, or is story featured just because it's the newest Lolnus kernel?

Boom.

[Anonymous Coward]

paravirtualization hypervisor.

Sounds like one hell of a Machine Gun.

SO EXCITED!

[ILuvRamen]

I'm so excited, I wish I could have stayed up until midnight in a huge line for it! HOW AM I SUPPOSED TO SLEEP NOW?!

Yeah, but

[Anonymous Coward]

yeah, but does it run... Oh. Nevermind.

Yay upgrade!

[nxtr]

I think I'll take the opportunity to upgrade to 2.2.26; I don't waste my time with unproven technology.

we dont like guests from xen

Yes, what they don't mention is that the XEN "guest support" is in the form of a crowbar.

Re:Boom.

[Fuji Kitakyusho]

Don't cross the streams. It would be "bad".

Hey! You butchered my second-most-loved meme, you insensitive clod!

On a more serious note, are these improvements dramatic, or is story featured just because it's the newest Lolnus kernel?

I don't know about dramatic, but the change does replace several core OS components, some of which generated quite a bit of buzz when development was first announced (too lazy to link some of the flame wars^H^H^H^H^H^H^H^H^H^H discussions that news of a new scheduler generated).

Obligatory.

[Anonymous Coward]

But does it run OS X?

Re:Boom.

[germansausage]

I'm fuzzy on the whole good/bad thing. What do you mean, "bad"?

Re:Answer: Linux will never be GPL3.

[BadAnalogyGuy]

Hello everybody out there using Linux -
I'm doing a (free) operating system based on GPL3 (just a hobby, won't be big and professional like Linux) for x86. This has been brewing since april, and is starting to get ready. I'd like any feedback on things people like/dislike in Linux, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things).

I've currently ported bash(3.2) and gcc(4.2.2), and things seem to work. This implies that I'll get something practical within a few months, and
I'd like to know what features most people would want. Any suggestions are welcome, but I won't promise I'll implement them :-)

PS. Yes - it's free of any Linux code, and it has a multi-threaded fs. It is NOT protable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that's all I have :-(.

Re:Boom.

Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light.

Re:A pre-packaged ISO, please...

[Fireflymantis]

It only costs your time. Rather than getting work done, you can spend hours compiling your software and acting arrogant.

I'm sold! I simply MUST get this onto my office workstation!

Re:Answer: Linux will never be GPL3.

[zsouthboy]

You forgot the hardcoded support for Swedish keyboard layout, only.

Why do that much work?

[Anonymous Coward]

Just take OpenBSD and re-release it under the GPLv3!

Re:You know the drill...

[Randle_Revar]

Lolnus?

I can has new scheduler?

I had new scheduler but Linus eated it :-(

Re:Boom.

[MoxFulder]

... the 'lumpy' reclaim algorithm, a userspace driver framework, the O_CLOEXEC file descriptor flag, splice improvements, a new fallocate() syscall, lock statistics, support for multiqueue network devices, various new drivers, and many other minor features and fixes. See the changelog [CC] for details."

OMG!!!!!! The O_CLOEXEC file descriptor flag is coming out!!! My friend Tiffany is, like, *totally* gonna freak when she hears about it.

Hot

[MrYotsuya]

the lguest 'Linux-on-Linux' paravirtualization hypervisor

Linux on linux, that's so hot!

Re:Answer: Linux will never be GPL3.

[Minwee]

Of course you realize that no project which launches with that kind of announcement could ever expect to succeed.

I mean, really. What are the chances?

1995

Richard, is that you?

Re:SO EXCITED!

[nacturation]

This kernel has virtual Linux on Linux action! Why would you even want to sleep?

Don't use "meme" as a euphemism for "cliché".

Seriously?? You don't really meme that, do you?

Re:You know the drill...

[SnowZero]

In SOVIET RUSSIA, cliché euphemisms you.

Blow by blow

[Anonymous Coward]

This version includes the new and shiny CFS process scheduler,

I know what I'm doing!

a simpler read-ahead mechanism,

And I knew it before you did!

the lguest 'Linux-on-Linux' paravirtualization hypervisor,

LeVar Burton would not approve of that kind of self-abuse!

XEN guest support,

Crabs are NOT invited to my head!

KVM smp guest support,

The sump reverses the M^V>K process?

and variable process argument length.

Oh great, now you'll never get them to stop bickering.

SLUB is now the default slab allocator,

Your build has now lost the battle of the bulge.

there's SELinux protection for exploiting null dereferences using mmap,

If you're going in those kind of holes, you better be wearing something slinky!

XFS and ext4 improvements, PPP over L2TP support.

No no, you put the TP over the PP 2 L8!

Also the 'lumpy' reclaim algorithm,

Mike Rowe? Have I got a job for you...

a userspace driver framework,

Better make it a rollcage.

the O_CLOEXEC file descriptor flag,

I thought only birds have those.

splice improvements, a new fallocate() syscall,

Your Linux will do anything for love but they WON'T do THAT!

lock statistics, support for multiqueue network devices, various new drivers, and many other minor features and fixes. See the changelog for details.

Whew. Time for my cigarette.

Re:Yeah, but

[SnowZero]

Well, that is kind of the point of virtualization, isn't it?

Re:The real Linux news today.

[kcbrown]

Exploit code was wildly popular on milw0rm, indicating that this local exploit has lots of potential.

Yeah, but it's a local exploit.

For it to be an issue the attacker has to get onto the box first. I'm running Linux, and it's so secure that there's no way they can get in and#(*%^W(#^# NO CARRIER.

Re:Ummm. Neat.

Aahhh... I love the smell of car analogy in the morning.

Re:we dont like guests from xen

[K. S. Kyosuke]

Sounds like xenophobia to me...

Fuck!

[robo_mojo]

And I just finished compiling 2.6.22.9 :( Fuck!

Personally I'll wait for the SP1 release

[robo_mojo]

Upgrade to 2.6.23 right now? Are you out of your mind? Everyone knows you're supposed to wait for the SP1 release before upgrading to a new operating system!

Re:Methinks...

[somersault]

I'm holding off upgrading until they implement the Harsh But Demonstrably Fair Scheduler

Re:Methinks...

[dotgain]

Just as long as my wife's not in charge, I don't care.

Re:Yay upgrade!

[zuricher]

Great. And now could we please move along and assign all these resources on a more important matter, like the XBMC linux port?

Re:You know the drill...

[MadnessASAP]

I feel a great disturbance in the meme.

Re:Yay upgrade!

[Nazlfrag]

Bah! the fools are stuck in the past, what with those stable, reliable distros. When will they ever convert to Gentoo?

And when I saw SO_EXCITED I thought it was a new option for sockets.

Re:Why do that much work?

[HeroreV]

That sounds like a very fun idea.

1. Person A obtains OpenBSD under the terms of the BSD license.
   
2. Person A modifies all source files, which the BSD license allows, to also include a GPLv3 license statement.
   
3. Person A distributes his modified copy to Person B.
   
4. Person B accepts the terms of the GPLv3 instead of the BSD license.
   
5. Person B strips out the BSD license, which he's allowed to do because he's not bound by the terms of the BSD license.
   
6. Person B distributes his modified copy of OpenBSD which is now only under the GPLv3 license.
   
7. Theo de Raadt explodes in a hurricane of rage, screaming that receivers of multi-licensed code must accept all licenses.
   
8. Lawyers all disagree with Theo.
   
9. Theo goes completely insane and ends up in a mental institution.
   

Any takers?
