Gentoo Weekly Newsletter 31 January 2005

Gentoo Weekly Newsletter
This is the Gentoo Weekly Newsletter for the week of 31 January 2005.

1. Gentoo News

Trusted Gentoo

Initially suggested by Joseph Pingenot[1], the members of Gentoo's crypto
herd have set the goal of Trusted Computing Group (TCG - formerly known as
Trusted Computing Platform Alliance or TCPA[2]) support in Gentoo on the
agenda for the year.
1. http://bugs.gentoo.org/show_bug.cgi?id=35574
2. http://www.research.ibm.com/gsal/tcpa/

TCG is an open standard for hardware specification defining cryptographic
functions (Trusted Platform Module - TPM) that keep private keys away from
system memory. The hardware also provides trusted boot functions (TCG
Software Stack - TSS) that ensure private keys cannot be used if the
operating system changes to an untrusted one.

TSS applications of the TCG architectures that would be desireable for
Gentoo are:

* trusted kernel execution (http://enforcer.sourceforge.net/[3],
* trusted grub execution[5]
* trusted kernel modules
3. http://enforcer.sourceforge.net/
4. http://trousers.sourceforge.net/
5. http://www.prosec.rub.de/trusted_grub.html

TPM allows storing of cryptographic keys in hardware rather than placing
private keys on the filesystem. Examples include:

* unlocking of encrypted filesystems
* OpenSSH server
* SElinux[6]
* Apache
* OpenCA certification authorities[7]
* GnuPG and SSH keychains
6. http://www.finux.org/Reprints/Reprint-Halcrow-OLS2004.pdf
7. http://www.acsac.org/2004/abstracts/81.html

If you are interested in donating hardware or undertaking development in
this area contact Henrik Brix Andersen[8] or Peter Johanson[9]. Developers
will need to work largely independantly, and to have a good understanding
of security architectures and C coding. A TPM emulator that may be of
assistance is available[10].

Looking for EM64T developers, hardware, and AMD64 "Arch-testers"

The Gentoo/AMD64 team has issued a request for developers who could help
extending support to Intel's x86-64 processors, the EM64T product line.
The devs will need to bring their own hardware and mainly do kernel
testing, since the chipsets on EM64T mainboards are different. Please
contact Jason Huebel[11] if you feel up to helping out with this.
11. jhuebel [at] gentoo

In a separate announcement[12], AMD64 is also looking for "Arch-testers"
or AT's, i.e. non-developers to help iron out bugs and mark applications
stable for a variety of ebuilds already available.

Gentoo/PPC GameCD released

The PPC team has prototyped the first completely graphical LiveCD for the
PowerPC platform featuring a 3D multiplayer OpenGL/SDL game called
Cube[13]. Designed for the PegasosPPC, a CD variant to run on Macintosh
hardware is already in the works. While the 198 MB GameCD is already
available for download from the mirrors (in the experimental/ppc/livecd
directory), a whole cluster of ODWs running Cube will be part of the
presentations in the Gentoo developer room at FOSDEM[14] in Brussels,
26-27 February 2005.

Project goals for 2005

Continuing our coverage of goals set by projects inside Gentoo Linux, this
week we look at the plans of the Hardened group:


* Review of current approach and policies
* Improvement of CFLAGS filtering (especially "-fPIC" and
* Introduce AMD64/Sparc64/PPC64 stages, more hardware in the future as
hardware is aquired
* Improved Grsecurity2 documentation
* Improved and extended SELinux support
* Develop and document RSBAC policies
* More and better documentation of everything
* Assimilate new developers
* Elect new Hardened Committee
* Introduce a forensics and rescue LiveCD
* Support and improve kernel patchsets
* Promote the Gentoo Hardened Project outside of Gentoo and raise
awareness within Gentoo

New old Portage utility

One of several Portage search utilities, portagedb, has been renamed to
"Ebuild Index" or eix recently. Developer Pythonhead acknowledges that
this alternative to esearch "gets better with every release" and lists eix
in his meta-thread:

* eix - Ebuild IndeX (search utility)[26]
* Portage utilities not in portage[27]

Is the beagle man's best friend?

Slow week in the English sections of the Forums, but the French had a go
at a piece of software comparable to the much-hyped SpotLight[28] that
Apple wants to integrate into their Tiger release of Mac OS X. It appears
that the Mono-based Beagle[29] is not only a completely free Linux
alternative to Apple's real time desktop search, it's also already usable,
at least to a certain degree...

Reminder on the ebuild upgrade policy

Jason Wever[31] sent out a reminder about ebuild upgrade policy:
"Recently, there have been a lot of ebuild upgrades with arch keywords
getting dropped completely. Please do not do this unless there is a
specific reason for it (security bug, broken dependencies, see policy),
and if there is a valid reason, please notify the affected arches as to
why you have dropped their keywords."

[RFC] Versioned eclasses

Daniel Goller[33] and Patrick Lauer[34] started a thread asking for
versioned eclasses. This proposal (which is a recurring topic every six
months or so) was burnt to a crisp in one of the largest flamewars the
gentoo-dev mailing list has seen in the last months, and remained

Gentoo-dev seems to be hacked

Around the same time as the "versioned eclasses" flamewar a second
high-traffic thread developed around signatures, identity and paranoia.
The initial questions around possibly broken signatures got forgotten
while devs and users discussed the problem of identity in mostly
electronical communications and some other tangential questions.

BAS/c troubles

Ciaran McCreesh[37] pointed out some problems with the new Buildtime and
Statistics client BAS/c. The following thread has lots of good information
for all the ebuild hackers among you how ebuilds should be written (and
some good examples what not to do)

5. Gentoo in the press

Gentoo/OpenSolaris media fallout

"Mixed feelings" best describe the open-source community's assessment of
Sun's OpenSolaris release. Regardless whether they're critical of Sun's
move or not, many authors tip their hats to Portaris and the
Gentoo/OpenSolaris project as a very interesting aspect of it. Here's a
list of press clippings covering both Sun's and Gentoo's announcements
from around the world:

* Sun lays groundwork for OpenSolaris community[39] (Computerworld
* Will Sun's 1600 patents suck the life out of Linux?[40] (CNET's David
Berlind blogging, contains an interview with Pieter Van den Abeele[41])
* Split Reactions to Sun's OpenSolaris[42] (Internet News)
* Gentoo für OpenSolaris angekündigt[43] (Golem.de, in German)
* Gentoo bald auch für Open Solaris[44] (Austrian daily newspaper Der
Standard, in German)
* Gentoo、パッケージシステムのPortageで"OpenSolaris"をサポート[45] (MYCOM
PC Web, in Japanese)
* Sun、OpenSolarisコミュニティーの基盤を構築[46] (IT Media, in Japanese)

Mad Penguin (25 January 2005)

"Gentoo done right"[48] is the title for a Mad Penguin article about
Vidalinux[49], the Gentoo spinoff installing via RedHat's Anaconda and
supplying binaries on a Gentoo core system. The Puerto-Rican distribution
- "essentially a stage 3 install" - receives an enthusiastic review, and
Author Adam Doxtater closes on recommending it "to anyone with a desire to
give Gentoo Linux a try but who might not have the time to compile
everything from scratch to get a basic system up and running."

Pro-Linux.de (25 January 2005)

The German online-only Linux magazine features the sales of Genesi's Open
Desktop Workstations in an article on PegasosPPC-Workstations with Gentoo
preinstalled[50]. Pro-Linux quotes last week's GWN announcement and adds a
few notes on the platform in general, identifying - among other things -
the ODW as "an Amiga reincarnation."
