kernel weekly news – 10.09.2011

Posted: September 10, 2011 in kernel

Hello everyone! We kick off this week’s edition with Linus’
announcement of 3.1-rc5 :

 So it's been another week, and it's time for another -rc.

However, is still down, and there really hasn't been
a ton of development going on, so I considered just skipping a week.
But hey, the whole point (well, *one* of the points) of distributed
development is that no single place is really any different from any
other, so since I did a github account for my divelog thing, why not
see how well it holds up to me just putting my whole kernel repo there

So while is down for the count, let's just see how github does:

NOTE! One thing to look out for when you see a new random public
hosting place usage like that is to verify that yes, it's really the
person you think it is. So is it?

You can take a few different approaches:

 (a) Heck, it's open source, I don't care who I pull from, I just want
a new kernel, and not having a new update from in the last
few days, I *really* need my new kernel fix. I'll take it, because I
need to exercise my CPU's by building randconfig kernels. Besides, I
like living dangerously.

 (b) Yeah, the email looks like it comes from Linus, and we all know
that SMTP cannot possibly be spoofed, so it must be him.

 (c) Ok, I can fetch that tree, and I know that Linus always does
signed tags, and I can verify the 3.1-rc5 tag with Linus known public
GPG key that I have somewhere. If it matches, I don't care who the
person doing the release announcement is, I'll trust that Linus signed
the tree

 (d) I'll just wait for to feel better.

Whatever works for you.

One thing to note: If you just do

  git pull

you probably won't get the tags, since it's not your origin branch. So do

  git fetch --tags 

too, so that you get not only the actual changes, but the tag that you
can verify too.

And I *would* suggest you just pull into an existing tree, rather than
clone a new copy. I bet the github people will appreciate that.

Anything worth saying about the changes themselves? The appended
shortlog pretty much speaks for itself: there really hasn't been much
excitement on the kernel development front.

Now, if you want to talk to me about dive logging software, that's a
whole different kettle of fish..

So as you can see, his mail touches the recent issue,
so make your choice and compile a new kernel today.

-Konrad Rzeszutek Wilk has xen stable/bug fixes for
the freshly announced -rc 5 :

 Please git pull the following branch from my backup git server:

git pull git:// stable/bug.fixes

It is based off git commit 60c5f08e154fd235056645e050f2cd5671b19125
Jeremy Fitzhardinge (1):
    xen/tracing: Fix tracing config option properly

Which you pulled in earlier (3.1-rc3?).

We got some ecstatic bug-fixes - one in particular has been in the tree since 2.6.27!
They are (in order of "oh-my-what-a-bug"):
 1). Don't enable the interrupts when a page fault has occurred - this ended up triggering
     when we were executing a IRQ handler and re-enabling the IRQ line!
 2). Respect the dom0_mem=max:X argument that the hypervisor can use to limit the amount
     of memory the initial Linux kernel would use. Without it, on largish (32GB>) the
     initial domain had tons of unused 'struct page' that were never going to be used.
 3). Lastly, print out a warning when the user uses specific Linux kernel parameters
     that we cannot handle ("nosmp" or "noapic").

The credit list is:

David Vrabel (1):
      xen: use maximum reservation to limit amount of usable RAM

Igor Mammedov (1):
      xen: x86_32: do not enable iterrupts when returning from exception in interrupt context

Konrad Rzeszutek Wilk (1):
      xen/smp: Warn user why they keel over - nosmp or noapic and what to use instead. 

-Thomas Gleixner has perf, scheduler and timer fixes for 3.1, Chris Ball introduces some MMC
fixes for -rc6, and that’s all for me for now. Although this has been a short edition, we’ll wait
and see what next week brings. So stay tuned and have a nice weekend.
