Hello, and be welcome to the 12th edition of the Weekly Kernel News!

-The first news for this week is Jan Kara’s pull request fot linux-fs (ext2 and ext3 in our case) aimed at -rc4, Frederic Weisbecker posting his pull request for the perf tree and Arnaldo Carvalho de Melo’s pull request for perf/core targetted at 2.6.36 .

-Sticking to the pull requests, we have also Dmitry Torokhov posting input updates for 2.6.35-rc1, Trond Myklebust with NFS client improvements, Tejun Heo with two fixes for the percpu tree and David Miller with networking fixes , quite a few of them, since they accumulated during Linus’ vacation, as the author explains.

-Neil Brown posted a pull request related to md, targetted @ 2.6.35, containing  various bugfixes, Thomas Gleixner posted various fixes for the core, x86, timer, scheduler, genirq and perf trees targetting also 2.6.35, Jens Axboe also has a pull request for  the block/IO subsystem (targetting -rc*) and Steven Rostedt posted a pull request for the tracing/perf/core tree aimed at 2.6.36 .

-Jeffrey Merkey posted an announcement of MDB Merkey’s Kernel Debugger x86_64 2.6.34 06-28-2010,  with the following summary : “http://merkeydebugger.googlecode.com/files/mdb-2.6.34-x86_64-06-28-2010.patch

This is the first full x86_64 version of MDB.  This implementation of MDB also uses the x86_64 and IA32 versions of the GDB disassmbler instead of the older IA32 disassembler from previous version of MDB.  bfd has been integrated into MDB which will support easy porting of MDB to other processor types.  I used the kdb disassembler GDB source base and added all the MDB features and layout (intel style).  This version also supports 8086 disassembly and IA32.  There is a short list of items left on the list and I will update these as I have more time to work on MDB.” Following is a list of fixes and todo’s, go check them out if interested.

-Junio C Hamano announced the release of git 1.7.11, which can be downloaded at http://www.kernel.org/pub/software/scm/git/ , and that is where one can also find RPM packages. The fixes list is too long to be posted here, but you can always check it out via web.

-Jeffrey Merkey comes back with the release of his MDB (see above) dated 29.06.2010,  introducing a few fixes :
“- fixed DS and W commands to output qwords in stack argument dump
– add find_extend_vma and follow_page to exported symbols
– add ds: and es: segment lookups in disassembler
– enable .TM flag to toggle memory read between physical and user space read/write for addresses < PAGE_OFFSET”

-Tony Lindgren asks Linus for the usual pull, in this case pertaining to omap fixes for 2.6.35-rc3, OpenSUSE’s own Greg Kroah Hartman posted a series of patches related to USB, staging and serial for 2.6.35-git, Dave Airlie posted fixes for drm, agp and fb, all part of the drm tree, John W. Linville posted some wireless fixes for 2.6.35 and Wim Van Sebroeck posted a pull request for the watchdog tree that introduces a  documentation fixi (for -rc3).

-Karel Zak announces the release of util-linux-ng v2.18 (stable) which you can download from the usual location : ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/v2.18/ .

-Junio C Hamano announced git 1.7.2.rc1 , available at the same URL as above, make sure you check it out or just update your distro.

-The vhost-net tree was updated by a pull request by Michael S. Tsirkin, asking to merge the tree for 2.6.35, while Jeff Garzik updated the libata tree with a few fixes and Paul McKenney updated the rcu tree with a revert commit, while Thomas Gleixner posted a pull request for the sched tree.

-Greg Kroah Hartman started a series of 149 patches as part of the review cycle of 2.6.32.16 : “This is the start of the stable review cycle for the 2.6.32.16 release. There are 149 patches in this series, all will be posted as a response to this one.  If anyone has any issues with these being applied, please let me know.  If anyone is a maintainer of the proper subsystem, and wants to add a Signed-off-by: line to the patch, please respond with it.

Responses should be made by Sat, July 3, 17:00:00 UTC UTC. Anything received after that time might be too late.

The whole patch series can be found in one patch at: kernel.org/pub/linux/kernel/v2.6/stable-review/patch-2.6.32.16-rc1.gz and the diffstat can be found below.” Greg also started posting the same series of patches, this time for 2.6.27.48, 2.6.33.6, 2.6.34.1 .

That’s all, folks! Have a sunny weekend!

Hi everyone, and welcome to this week’s edition! As usual, new commits, patches and fixes are waiting, so let’s dive in!

-Karel Zak announced the release of util-linux-ng v 2.18-rc2, available at ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/v2.18/ ; a changelog is also available in the announcement.

-Matthieu Desnoyers announced Userspace RCU 0.4.6 with the following (short) announcement text : “I just released userspace rcu 0.4.6, which contains added ARMv7l support. It also includes the new make check target. I skipped 0.4.5 because I updated the README file after the release.”

-Jeffrey Merkey announced Open Cworthy 6-19-2010 x86_64 fixes with the following changes : “Fixed NWSCREEN pointer size mismatch on x86_64

Fixed build problems on x86_64
Fixed Memory Overwrite glibc message on Fedora 13 x86_64
Upgraded memset and memcpy functions for x86_64

Tested on a 4 processor opteron HP Proliant running Fedora Core 13 x86_64 and FC8 ia32”

-Jean Delvare pushed hwmon fixes for Linus, targetting 2.6.35, Jesse Barnes comitted  a fix for the PCI tree (for -rc3), Paul Mundt posted a pull request to Linus regarding sh updates for -rc4 and John W. Linville posted his pull request regarding the wireless tree (22.06.2010), with just one fix. As some of you may already know, Linus is in a vacation, so the number of git pull requests is smaller than usual.

-Matthieu Desnoyers made an announcement pertaining to the release of LTTng 0.217 for 2.6.34, describing the update as follows : “LTTng 0.218 adds a missing irq_desc export in kernel/irq/handle.c, which only affects sparse irq configurations. This omission only appeared in 0.217.”

-Henrik Rydberg announced the release of mtdev 1.0.1, explained as “mtdev – Multitouch Protocol Translation Library (MIT license)

The mtdev library is a kernel input event stream translator, which greatly simplifies multitouch handling in applications. The input events are simply routed through mtdev, which transforms them to a uniform stream of MT slot events. Software finger tracking is performed when needed, making all devices appear as if they had tracking capabilities. For further details and the source git tree, see

http://bitmath.org/code/mtdev/

The bulk of mtdev has been around since 2008, as part of the Multitouch X Driver project (http://bitmath.org/code/multitouch/). By releasing mtdev as a stand-alone package under the free MIT (X11) license, we hope to simplify the adoption of the MT event protocol in applications.”

-Rafael J. Wysocki posted the list of reported regressions from 2.6.34 related to 2.6.35-rc3, as well as a list of reported regressions between 2.6.33 and 2.6.34.

-The H Online published an article titled “Linus resolves to apply a strict policy over merging changes”,  with the following headline : “It would appear that Linus Torvalds has resolved to apply a strict policy of accepting only bug fix changes to the kernel after the merge window has closed. Torvalds has also stuck his oar into the debate over the Android suspend block API and made the situation even more complicated.”

-Rusty Russell published few virtio fixes targetted at -rc3, Steven Rostedt posted a pull request for Ingo Molnar related to the tracing tree, and that’s about it for this week, a week with shorter news and no rc, nevertheless with some interesting points worth reading.

Have a great weekend! See y’all next week!

Hello, and welcome! Looks like just after I finished my article, 2.6.35-rc3 was announced, so I will have to make the announcement in this week’s edition. Let’s begin.

-LWN.net’s Jonathan Corbet posted an article titled “Kernel Prepatch 2.6.35-rc3” , marking the announcement of the 3rd release candidate. Link is here : http://lwn.net/Articles/391864/rss .

-Michal Marek posted kbuild fixes, while Dominik Brodowski posted also some small fixes for PCMCIA (-rc3), David Miller has his usual dose of fixes for networking, Rafael J. Wysocki posted a resume fix for x86 (the pm tree) and Len Brown posted ACPI patches for -rc3.

-Jeffrey Merkey annonced the 11.06.2010 release of the Open Cworthy Linux libraries with the following changelog : “FIXES

Corrected pthread concurrency issues with ncurses and ncursesw.  These libraries are not pthread safe on linux 2.6.33 and later kernels and require mutexes for access to any of the screen refresh() calls or they will corrupt the video display removed vitriolic messages from the code and comments this version supports multiple update panels with pthread safe calls to ncurses libraries.  Supports VT100, VT220, XTerm, and Linux terminals.  Dumb terminal and ANSI still have some issues but these problems are ncurses related.  Sample IFCON program included.

This version was tested on a 4 processor Opteron HP Proliant Server.”

-Here comes, ladies and gentlemen, the offcial announcement of 2.6.35-rc3, made, of course,  by Linus Torvalds : “So I’ve been hardnosed now for a week – perhaps overly so – and hopefully that means that 2.6.35-rc3 will be better than -rc2 was. Not only do we have a number of regressions handled, we don’t have that silly memory corruptor that bit so many people with -rc2 and confused people with its many varied forms of bugs it seemed to take, depending on just what random memory it happened to corrupt.

One effect of being strict is that this is likely the smallest -rc3 we’ve had in a long long time. The diffstat summary line for the week
looks like this:

165 files changed, 1624 insertions(+), 859 deletions(-)
from 159 commits, and even then the biggest single change was due to moving some functions around in iwl-agn.c, rather than a lot of actual changed lines.

So give it a good testing.

Linus”

-Benjamin Herrenschmidt posted a small group of powerpc fixes for 2.6.35, Takashi Iwai has sound fixes for 2.6.35-rc4, Chris Mason has also some btrfs fixes,  Tomi Valkeinen has two fixes for the OMAP framebuffer driver, Paul E. McKenney  posted some RCU-lockdep splat fixes, and John W. Linville announced a series of fixes for the wireless tree : “Here is another passel of of fixes intended for 2.6.35. Included are some build warning fixes, a PCI identifier, a fix for premature IRQs during hostap initialization, a fix for a warning caused by failing to cancel a scan watchdog in iwlwifi, a fix for a null pointer dereference in iwlwifi, and a fix for a race condition in the same driver.  Also included is the MAINTAINERS change for the orphaning of the older Intel wireless drivers.  All but the last few warning fixes have spent some time in linux-next already.”

And…that’s it for this week! Have a sunny and enjoyable weekend!
