1. Linux 2.6.12-rc3-mm3 Released
4 May - 18 May (21 posts) Archive Link: "2.6.12-rc3-mm3"
Topics: Device Mapper, Kernel Release Announcement, User-Mode Linux
People: Andrew Morton
Andrew Morton announced Linux 2.6.12-rc3-mm3, saying:
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12-rc3/
2.6.12-rc3-mm3/
+ device mapper updates
+ more UML updates
+ -mm seems unusually stable at present.
2. New mini_fo Virtual Filesystem
9 May - 13 May (14 posts) Archive Link: "[ANNOUNCE] mini_fo-0.6.0 overlay
file system"
Topics: Small Systems
People: Markus Klotzbuecher, Eric Lammerts
Markus Klotzbuecher said:
mini_fo is a virtual kernel filesystem that can make read-only file systems
writable. This is done by redirecting modifying operations to a writeable
location called "storage directory", and leaving the original data in the
"base directory" untouched. When reading, the file system merges the
modifed and original data so that only the newest versions will appear.
This occurs transparently to the user, who can access the data like on any
other read-write file system.
mini_fo was originally developed for use in embedded systems, and therefore
is lightweight in terms of module size (~50K), memory usage and storage
usage. Nevertheless it has proved usefull for other projects such as live
cds or for sandboxing and testing.
For more information and download of the sources visit the project page:
http://www.denx.de/twiki/bin/view/Know/MiniFOHome
ChangeLog for mini_fo-0-6-0:
+ support for 2.4 and 2.6 kernels.
+ mini_fo now implements all file system operations.
+ many bugfixes and code cleanup.
Eric Lammerts liked this work, but pointed out, "The module taints the kernel
because of MODULE_LICENSE("LGPL"). Since all your copyright statements say it's
GPL software, better change this to "GPL"." Markus sent a patch to fix this.
3. Linux 2.6.12-rc4-mm1 Released
12 May - 16 May (33 posts) Archive Link: "2.6.12-rc4-mm1"
Topics: Kernel Release Announcement
People: Andrew Morton, William Lee Irwin III
Andrew Morton announced Linux 2.6.12-rc4-mm1, saying:
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12-rc4/
2.6.12-rc4-mm1/
+ Added Herbert Xu's ipsec tree to the -mm lineup, as git-ipsec.patch
+ Lots of updates all over the place
William Lee Irwin III pointed out that the uml-remove-elfh file was actually
empty. Andrew replied, "Yeah, I couldn't work out a way of generating a patch
which removes a zero-length file, so that's there as a reminder to ask Linus to
remove the thing by hand."
4. Net Driver Development Switches From BitKeeper To git
12 May - 15 May (8 posts) Archive Link: "git repository for net drivers
available"
Topics: Version Control
People: Jeff Garzik, Krzysztof Halasa
Jeff Garzik said, "Although I have over 200 net driver patches to go through in
my 'Pending' folder, I have fully converted the existing netdev-2.6 repository
from BitKeeper to git. This includes the wireless-2.6 repository. rsync://
rsync.kernel.org/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git" Krzysztof
Halasa asked, "Do you prefer plain patches or GIT repository on kernel.org to
merge for future (and "current") updates? I haven't set a public repo up yet,
but it's a matter of seconds." Jeff replied, "For now, plain patches."
5. Linux 2.6.11.10 Released; Stable Tree Migrates To git
16 May (6 posts) Archive Link: "Linux 2.6.11.10"
People: Greg KH, Dave Jones, Stephen Tweedie
Greg KH said:
Due to a recently announced security issue with the current kernel, we (the
-stable team) are announcing the release of the 2.6.11.10 kernel.
The diffstat and short summary of the fixes are below.
I'll also be replying to this message with a copy of the patch between
2.6.11.9 and 2.6.11.10, as it is small enough to do so.
Also, the 2.6.11.y tree is now being kept in git. It can be found at:
rsync://rsync.kernel.org/pub/scm/linux/kernel/git/gregkh/linux-2.6.11.y.git
and can be browsed at the normal kernel.org git web browser:
www.kernel.org/git/
One of the fixes was a root exploit in the raw device, credited to Dave Jones.
Dave said, "I was just the bringer of bad news this time ;-). Stephen Tweedie
spotted the real problem here, and based his patch on one from Jan Glauber."
6. Net Driver Updates; Some git Tricks
16 May (2 posts) Archive Link: "[git patches] 2.6.x net driver fixes"
People: Jeff Garzik, Linus Torvalds
Jeff Garzik said to Linus Torvalds:
Here's a first experimental git push from me. The git URL is rsync://
rsync.kernel.org/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git
but it should be noted that I would like you to pull the 'misc-fixes'
branch. I'm told that branches are supposed to live in .git/refs/heads, so
there you will find netdev-2.6.git/refs/heads/misc-fixes.
Does that work?
Changelog and patch for review attached.
Linus pulled Jeff's patches, and incorporated them into his own tree. He also
replied:
It's wonderful if you also do a "diffstat" on the thing, since my merge
scripts will always show that to me, and I can verify at a glance that it
matches what you thought you sent me.
Also, if you are really nervous, the "git-diff-tree" thing is actually
quite good at generating changelogs, so you can do something like this:
git-rev-tree HEAD ^ORIG_HEAD | cut -d' ' -f2 | git-diff-tree -v -p --stdin
| less -S
which means: give me a list of all commits that are in HEAD but not in
ORIG_HEAD (replace with whatever markers you have, in this case you'd use
"misc-fixes" instead of HEAD and some marker - maybe the SHA1 - for my last
base), then take just the SHA1 of that list of commits, and show a verbose
diff of each of the commits with the patch.
For example, the output of the above command (after I merged from you) is
appended, so you can see exactly what I merged.
7. Linux Cluster Summit 2005 Scheduled
18 May (1 post) Archive Link: "[ANNOUNCE] Linux Cluster Summit 2005"
Topics: Clustering
People: Daniel Phillips, Heinz Mauelshagen
Daniel Phillips said:
Linux Cluster Summit 2005
June 20 and 21, Walldorf, Germany (Near Heidelberg)
Sponsors: Red Hat, SAP AG, Oracle, HP, and Fujitsu-Siemens.
The goal of the two-day Linux Cluster Summit workshop is to bring together
the key individuals who can realize a general purpose clustering API for
Linux, including, kernel components, userspace libraries and internal and
external interfaces. Results of this workshop will be presented to the
Kernel Summit the following month.
The workshop is to be held in Walldorf, the hometown of SAP, Europe's
biggest software company.
This is in the south/central part of Germany, in an adjoining town of
Heidelberg. Frankfurt and France (order the menu!) are within easy driving
distance. It is very picturesque. There is a lot to see and do in the
vicinity for those who are interested. We are planning a field trip for the
day following the workshop for those who want to stay an extra day and see
some sights. Details have not been finalized yet. Note that June 21 is the
first day of tutorials at LinuxTag and June 22 is the LinuxTag Business
Congress. You will be able to attend the rest of LinuxTag if you wish. It's
free!
Unfortunately, space is limited. We can accommodate about 100 attendees.
Registration is by invitation for 70 participants, including those who
attended last year, and 30 seats are available on a first come, first
served basis. There is no charge for this workshop. You will only be need
to arrange travel and accommodation. A list of recommended hotels and other
accommodation will be posted here.
The full agenda will be posted here, in the next few days:
http://sourceware.org/cluster/events/summit2005/

8. Resource List For A Kernel Newcomer
19 May (6 posts) Archive Link: "How start in Kernel Development"
Topics: Microkernels: Mach
People: Tommy Reynolds, James Morris, Lee Revell, Niraj kumar, Steven Rostedt
Weber Ress how one might get started in Linux kernel development. Tommy
Reynolds suggested, "Start by visiting http://www.kernelnewbies.org, and after
reading that stuff, check the http://janitor.kernelnewbies.org/ page to pick a
small starting point." James Morris added, "Also see the kernel-mentors mailing
list: http://www.selenic.com/pipermail/kernel-mentors/" Steven Rostedt also
recommended three books:
* Understanding the Linux Kernel ISBN: 0596002130 (http://www.amazon.com/exec
/obidos/ASIN/0596002130/qid%3D1117999617/sr%3D11-1/ref%3Dsr%5F11%5F1/
002-1453694-3744833)
* Linux Kernel Development ISBN: 0672327201 (http://www.amazon.com/exec/
obidos/ASIN/0672327201/qid%3D1117999640/sr%3D11-1/ref%3Dsr%5F11%5F1/
002-1453694-3744833)
* Linux Device Drivers ISBN: 0596005903 (http://www.amazon.com/exec/obidos/
ASIN/0596005903/qid%3D1117999654/sr%3D11-1/ref%3Dsr%5F11%5F1/
002-1453694-3744833)
Lee Revell added, "Just in case you don't know it from school, equally
essential is UNIX Internals, ISBN: 0131019082 (http://www.amazon.com/exec/
obidos/ASIN/0131019082/qid%3D1117999703/sr%3D11-1/ref%3Dsr%5F11%5F1/
002-1453694-3744833) . It's OS agnostic (though the author likes Mach a lot),
and unlike the above books it covers many features Linux does not yet have,
like priority inheritance."
Niraj kumar also suggested, "Look at this page , there are lots of good
pointers ... http://jungla.dit.upm.es/~jmseyas/linux/kernel/hackers-docs.html"
