Sorry if I have overlooked something, but I've been using zen-sources for a couple of months now (half a year really) and I am really liking them so far. The only thing I've been wondering about is whether or not there will be any new ebuild for it. I've seen gentoo-sources being pushed to 2.6.35 a while ago and thought zen would surely follow soon. However, to my surprise it did not, or rather it did, but was not pushed as an ebuild to portage as far as I can see. I've just unmasked the 9999 ebuild, so it's not really a big problem, just wondering.

We don't do the portage releases they are released after we announce and upload the patch

Zen1 was skipped due to issues, but git has kept up and zen2 was released today

Oh yeah, no offense then. I was just wondering why there was no 35-zen showing up on my morning updates and looked at the official site, where I saw the release without looking at the release date.

In every case, please provide .config for compilation issues so we can reproduce and fix ;) I'll fix classic rcu by zen3

I still happen to be on 2.6.34-zen1. Even still I'd like to sing the praises to BFS.

The box I have linux on is my server and it's primary purpose to to record and encode a very large about of HD TV that can be publicly downloaded. I've scripted the whole backend for taking advantage of the quad core as best as I can, though unfortunately, due to how I have backgrounded some encoding tasks, I woke up to a surprise.

I had about 45 instances of mencoder chugging away with a load average of ~65 with all instances niced to -15. Took about a 2 minutes in htop, but I managed to renice everything to 19 to restore the systems responsiveness. Everything still worked without the renice, but had a bit of lag. It looks like it will all finish up within the next 2 or 3 hours, but I'm happy to see how stable and functional my server remained :)

There is a patch which re-enables make xconfig (uses qt4). Would it be possible to integrate it in zen-sources?
http://dev.gentoo.org/~mpagano/genpatches/trunk/2.6.35/2900_xconfig-with-qt4.patch

I applied it to 2.6.35-zen2 and it works :)
Code:
/usr/src/linux-2.6.35-zen2> patch -p1 < /tmp/2900_xconfig-with-qt4.patch                     
patching file scripts/kconfig/Makefile
Hunk #1 succeeded at 235 (offset 12 lines).
patching file scripts/kconfig/expr.h
Hunk #1 succeeded at 170 (offset -1 lines).
patching file scripts/kconfig/qconf.h
patching file scripts/kconfig/qconf.cc
Hunk #34 succeeded at 1704 (offset 3 lines).

I've used the 2900_xconfig-with-qt4.patch on all my kernels since it was out, including 2.6.35-zen2. Can't say how nice it is to be able to use xconfig without having to have qt3 installed. :D IIRC, I asked the zen devs to include it, but it hasn't been in here yet. This (or something similar) should go into all mainline kernels immediately. I can't see any reason why this isn't a big priority, as many, many kernel rollers relied on xconfig and its wonderfu GUI interface for years. It's absolutely without equal for ease of use in digging around into kernel config options.

Many thanks to mpagano for providing this patch. It certainly again makes kernel configuring a pleasure instead of a real PITA. At least that's my opinion.

This should be (or was in the past) included in zen.git since i remember putting it there ages ago, but this isn't much help as zen.git is useless until one of us gets the time to port everything to .36-rc. I'll put the patch in zen-stable tomorrow.

You guys probably know already, but I had to disable aufs to get the 2.6.35-zen2 compiled. I can give you the complete log this afternoon, if you want.

When is the regular zen (unstable) going to be updated with 2.6.36 release candidates?

FYI (you probably already know): http://sota.gen.nz/compat1/ http://sota.gen.nz/compat2/

tried to merge git diffs (for 2.6.36-rc) on 2.6.35 (don't apply cleanly) in a patch (that I'm using now on top of git-zen3): http://pastebin.com/mJjPh7nt

temporary workaround for disabling support for 32bit-ELF:

http://seclists.org/fulldisclosure/2010/Sep/273

if you have 32bit-support for flash and other minor stuff: simply update to to 64bit flash (codename: square)

still FYI, the just released 2.6.35.4-5 patch (that fixes also the problem above) applies fine (except for the extraversion in the Makefile ;) ) to zen-stable.

EDIT: tnx steven :)

Hi,

just because I tested it : I can say that's I didn't not worked for me, at least for this exploit. On my two gentoo machines (see my signature), with kernel 2.6.32-hardened-r9 and 2.6.34-zen1-r2, it seems only prevent 32 bits applications to be executed, but the exploit success. Then, I applied theses two patches (here and here), and the exploit failed... Well, that's what my experience for this.
