Kernel Traffic #312 For 5 Jun 2005

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.

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.

• Added Herbert Xu's ipsec tree to the -mm lineup, as git-ipsec.patch
• Lots of updates all over the place

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/

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.

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.

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:
