Every so often, somebody shows up on the linux-kernel list with the same
bright idea: separate the device drivers from the rest of the kernel and
release them independently. Then drivers could be installed or updated
without having to change the entire kernel. This idea never gets very far;
among other things, it implies the creation of a stable driver API, which
is just
not in the
plans. But the idea keeps coming back anyway.
When Novell's breathless
press release, describing a "device driver breakthrough" which "solves
Linux device driver compatibility issues," your editor's first thought was
that this old idea had returned yet again. This breakthrough process
"allows customers to obtain drivers independently of Novell kernel
updates," after all, and is said to make life easier for vendors. As it
turns out, however, Novell has no plans for defining any sort of stable
kernel API; instead, it has created a mechanism making it easier for
vendors to cope with the existing, dynamic API.
Essentially, a vendor with a driver for its hardware can approach Novell,
pay whatever fee is required to become a "partner," and have its driver
distributed through the SUSE YaST mechanism. If the partner supplies
versions of the driver which work with distributed SUSE kernels, Novell
will make sure that each user gets the right version. Novell will provide
API change notifications, helping vendors to keep their drivers working
with current kernels. If the vendor becomes an Extra Special partner,
Novell will take care of much of the driver updating work themselves.
To some, this program looks for a way for Novell to help vendors who ship
proprietary drivers. And there may be some truth to that view. But the
real customer base may be elsewhere. Imagine that you are a vendor selling
products into a highly competitive market. When your new widget comes out,
you do the right thing and contribute a driver to the mainline tree. Even
if the driver is accepted on the same day (a relatively unlikely course of
events), it will not appear in a released kernel for a month or two, and it
will not show up in released distributions for some months (or years) after
that. By the time normal users can install the driver, the device is already
obsolete and being replaced by something newer, shinier, and faster.
And, in any case, having the driver in new distributions is of little help
to customers who are running older kernels and don't want to change that.
The Novell program will make it easy for this vendor to make drivers
available for the range of currently installed SUSE systems, without
forcing a kernel upgrade on their customers. If the program is done right,
it could change the landscape for the better: vendors would have an easier
time supporting the range of distributor kernels, and users would get
current drivers, even on older systems. If done wrong, it could lead to
more out-of-tree drivers, but Novell appears to have anticipated that
concern. From the driver
partner FAQ:
As an active member of the open source community, Novell's position
is clear: The best place for partners to develop kernel drivers is
upstream in the kernel.org source tree, where kernel driver code
benefits from thorough review and community involvement. Novell
promotes having all Linux device drivers be a part of the official
kernel.org source tree.
As long as vendors use this program as a backporting mechanism, it will do
nothing but good for everybody involved. If they use it as a way to avoid
the kernel development process or the need to release their code, the
benefits will be rather less. The initial signs are good enough, however,
that it is worth wishing Novell luck in this endeavor.

With a great deal of fanfare, Sun Microsystems used its podium at JavaOne
to
announce a change in the
Java licensing terms intended to make it easier for distributors to ship
Sun's Java implementation. To this point, the terms have been so difficult
that few distributors bother; those wanting to run Java code must either
install Sun's implementation themselves, or go with one of the free
alternatives. Sun, perhaps seeing that said free alternatives are rapidly
improving, has tried to reestablish its own dominance by way of a small
licensing tweak. It is a half measure at best.
Sun's new terms go under the name "Operating System Distributor License for
Java," or "DLJ" for short. As always, when pondering licenses, one must go
to the actual text. So, for the curious, a look at the text of the DLJ
(v1.1) is warranted. The core of the DLJ is this:
Sun also grants you a non-exclusive, non-transferable, royalty-free
limited license to reproduce and distribute the Software, directly
or indirectly through your licensees, distributors, resellers, or
OEMs, electronically or in physical form or pre-installed with your
Operating System on a general purpose desktop computer or server,
provided that...
So distributors can now ship the Java code as part of the operating system,
assuming they meet all the conditions - and there are several of those.
They include some obvious ones, such as indemnification of Sun from
liability, and some that one would expect, such as the requirement that the
software be distributed without modifications. Some of the other
conditions are interesting, though. Consider:
(b) the Software is distributed with your Operating System, and
such distribution is solely for the purposes of running Programs
under the control of your Operating System and designing,
developing and testing Programs to be run under the control of your
Operating System;
So the license only applies to operating system distributors. This clause
would appear to make it impossible for a third party to distribute Java
packages for somebody else's distribution. So this license may not improve
the lives of people who run distributions from organizations which will not
distribute non-free code at all.
Next condition:
c) you do not combine, configure or distribute the Software to run
in conjunction with any additional software that implements the
same or similar functionality or APIs as the Software
So Sun's Java remains incompatible with any free Java implementations and,
presumably, a fair amount of related code. How this term might affect the
combination of Sun's Java and Eclipse is an interesting question.
Finally, there is a term stating that if any compatibility issues arise
"caused by the interaction of the Software with your Operating
System," the distributor has 90 days to fix the problem or stop
distributing Java. It is unlikely - but not inconceivable - that such a
term could be used to pressure a distributor to change Linux system call
semantics which could be deemed to cause incompatibilities.
This license can be advantageous for distributors with mechanisms for
distributing non-free software. Some of them may now be able to ship Sun's
Java code for the first time. Thus, for example, Java has just landed in Debian's non-free
repository; Ubuntu and Gentoo seem interested as well. But the new
license will not help Fedora users, since there is no place in Fedora for
non-free code (though what Red Hat does with RHEL could be different). For
all the hints made at JavaOne regarding the eventual open-sourcing of Java,
this code remains resolutely non-free at this time. Sun's slightly more
friendly license has not changed that fundamental fact.

Frequent LWN readers will be well aware that your editor has had some real
fun playing with
Rockbox, a set of
GPL-licensed firmware for digital music players. So the Rockbox 3.0
release, originally scheduled for March 15, is of more than passing
interest. This release will offer a number of new features:
- The addition of the iRiver H1xx and H3xx players as fully-supported
targets. Rockbox works on a number of other players as well (notably
iPods and the iAudio X5), but those platforms are not quite ready for
a stable release yet.
- Several new games, including Jewels,
Brickmania,
Chessbox,
Bubbles,
and others. Players with suitable displays can even run Doom.
- Support for Unicode and translations to 28 languages.
- New codecs, including WAV playback on Archos models and AIFF.
- The Tag
Cache music database, allowing the user to browse through the
collection based on several attributes.
- A built-in five-band parametric equalizer.
- High-quality, lossless recording on platforms which support it.
There are, of course, many other improvements to the code which help to
make it more robust and maintainable, but which tend not to show up on
feature lists. Your editor has been running the occasional daily build
with good results. This looks to be a release which exposes Rockbox to a
wider user base and, in general, draws more attention to the project.
Only one problem remains: it doesn't all work yet. There are a number of
codec issues, such as confusion when the user skips around too much. A
number of trouble reports with the H1xx models have been posted. Battery
life on the H3xx is still far less than with the iRiver firmware. In
general, the list
of open bugs is on the long side for a project on the verge of a stable
release.
The Rockbox developers thus find themselves in a place familiar to many
projects: trying to decide when to make a major release. Putting out a
buggy system would not endear Rockbox to many of its users, and could set
the project back severely. Meanwhile, however, the ongoing feature freeze
has brought development to a stop and is creating a fair amount of patch
pressure. The developers would very much like to get this release out of
the way and move on to working on the new, fun stuff.
Getting releases out is one of the biggest challenges faced by many free
software projects. There is a natural tension between the creation of
truly stable releases and going on to develop the Next Cool Thing. A
number of techniques have evolved as a way of resolving this conflict:
The Rockbox developers do not appear to welcome the idea of creating
a separate development branch. So some sort of compromise between a timely
release and a bug-free release will have to be found. There is some
sentiment for putting out 3.0 on Monday the 22nd, with known bugs if need
be. The worst of those bugs might subsequently be fixed in an update
release shortly thereafter. So, while Rockbox 3.0 will doubtless make
many users entirely happy, it may well be a true "dot-zero" release for
others.

As
the previous article in
this series pointed out, one of the key developments in the rise of
open content was the drafting of suitable licenses to codify the
freedom to use these materials in various ways. One important licensing option
is that of modifying open content to create new works. Licenses may
open up the possibility of such collaborative ventures, but on their
own are not enough. Practical tools are needed to help people to
work together on open content. For that, software code is required
alongside the legal code, and application development has played just
as important role in the rise of open content as the refining of
appropriate licenses.
The
catalytic effect of tools can be seen in the sphere of blogs, which
represent a very popular, if coarse-grained, kind of online
collaboration. Several online Web diaries were around as early as
1995, the same year that the authors of Suck's
mordant posts first stepped onto the punishing daily treadmill that
has become a hallmark of top blogs. But the term “weblog”
only appeared
in December 1997, and was shortened to “blog”
in 1999, by which time there were just 23 of them according
to one count.
The
trigger for their rapid growth was the arrival of tools such as
LiveJournal, Pita, Blogger and Groksoup in 1999 that made creating
blog posts as easy as sending an email. Once the medium began to
take off, keeping up with all the postings became a problem.
Technology provided the solution through the Really Simple
Syndication (RSS)
standard, which grew out of earlier work by Dave Winer and Netscape.
Once in place, this apparently obscure XML standard allowed blog
readers to subscribe to a blog feed – vastly easier than going
to a blog and reading posts one by one.
The
availability of this technical solution drove the readership of blogs to
even higher levels. Now the problem became not so much reading the
posts you had subscribed to, but finding blogs of interest among the
millions out there. The solution – dedicated blog search
engines like Technorati –
flowed from another of Dave Winer's technical innovations: the blog
ping. Each time someone made a post to a blog created with
Winer's software, the program pinged his site weblogs.com,
which held a record of all such postings. Blog search engines like
Technorati could therefore use the pings as a signal to refresh their
indexes for the site in question, ensuring that they were always
up-to-date. By contrast, conventional search engines tend to be days
or even weeks behind the rapid posting rhythm that distinguishes
blogs from traditional Web pages.
Blogs
are clearly collaborative – their essence is the intellectual
give-and-take between those posting, quoting and linking, and those
commenting, which together create a kind of patchwork communal
document. But to allow a more thoroughgoing and fine-grained
collaboration, where texts could be modified right down to the level
of individual words, a new kind of software had to be developed, what
came to be called the wiki.
Significantly,
it was in the world of coding that this solution emerged. Ward
Cunningham, now employed
by the Eclipse Foundation, is well-known for his work on areas like
agile development and
extreme
programming. Many of agile development's principles read as if
they were referring to open source and open content, notably in
valuing “individuals and interactions over processes and
tools,” and “customer collaboration over contracts
negotiation”.
Another
important field that Cunningham has been associated with is design
patterns, notably through his Portland
Pattern Repository. It was for the latter that Cunningham
created WikiWikiWeb
in 1995 as a way of
facilitating the exchange of ideas between programmers. The name
“wiki” comes from a Hawaiian term meaning
“quick”, and was chosen in part for its alliteration with
the word “Web”, mimicking “WorldWideWeb”.
The “quickness” refers to the ease with which Wiki pages
can be added or edited, allowing content to be worked on in a true
collaborative fashion.
This
apparently minor modification of previous Web technologies has led to
a proliferation of large-scale collaborative open content, both on
the public Web and, increasingly, on corporate intranets. Perhaps
the most famous example is Wikipedia,
which grew out of Nupedia,
an earlier online encyclopedia. Nupedia did not employ the wiki's
completely open approach for content creation, and never got beyond
producing a handful of articles, whereas Wikipedia has already passed
the one million article mark for the English language alone.
Alongside
Wikipedia there is Wikimedia
Commons, which offers non-textual open content – images,
sounds and videos. But unlike the main Wikipedia articles, these are
rarely edited or modified, even though many are released under
licenses that would permit this. Similarly, the huge holdings of
open content images on Flickr
tend to be used as they are, rather than as the basis for derived
works. As well as these consolidated collections, there is
Yotophoto, a dedicated open
content search engine for images, and similar facilities on Google,
Yahoo
and the open source Nutch
(all available from the Creative Commons search
page, included by default among the Firefox search engines),
which allow material to be found across the Web.
The
ready availability of graphical open content raises the question of
what might be done with it. Tools like GIMP
have been around for years, but so far there does not seem to be the
same kind of broad collaborative tradition for graphics as there is
for texts. An interesting first attempt can be found in Kollabor8,
and recently the film “Elephant's
Dream”, produced using the 3D graphics creation package
Blender, has
been released
under a Creative Commons license.
One
area of non-textual open content where collaboration does seem to be
thriving is that of music. This is probably for both historical and
technical reasons. Musicians have always used the work of others as
springboards for their own music, often incorporating tunes, motifs
or chord progressions directly. In addition, the well-defined
time-based nature of music (beats/bars/phrases) provides an
easily-grasped framework within which fragments/samples from various
sources can be placed either sequentially or simultaneously –
something lacking for graphical images, where spatial relationships
are not so formally defined. The abundance of high-quality open
source music creation, editing and mixing software may be another
contributory factor.
Whatever
the reason, open content music is flourishing, as the existence of a
number of music sites offering material for remixing indicates. One
recent commercial example is My
Life in the Bush of Ghosts [Flash], by David Byrne and Brian Eno, while,
on the non-commercial side, the Creative Commons site has a
flourishing audio/music
section. Past and present projects found there include the Wired
CD, which offered tracks from major artists that were made freely
available for remixing (though usually only for non-commercial
purposes), and the ccMixter site.
The latter encourages musicians to upload samples, and to take each
other's music for use as the basis of new open content works which
can then be added to the pool of raw materials for others to work on.
An alternative approach is offered by MyVirtualBand,
which enables collaboration to take place even earlier in the
creative process.

Security
May 17, 2006
This article was contributed by Jake Edge.
It would seem obvious that protecting the integrity of election
results would be the paramount goal of a company that provides voting
equipment, but a recent
report (PDF)
indicates otherwise.
BlackBoxVoting.org released
a report by Harri Hursti last week that documents extremely serious flaws
in the design of touchscreen voting terminals from Diebold Election Systems
that could lead to an unscrupulous person or organization having complete
control of the software on those systems.
An attacker with physical access to the voting terminal can permanently
change the programming of a terminal in a way that is difficult or
impossible to detect. With a PCMCIA memory card, phillips-head screwdriver,
and 5 minutes of time, any portion of the
software that runs on the terminal can be modified. It is not just the
voting application that can be replaced; the operating system
and even the bootloader can also be changed via this mechanism.
No tamper resistance or detection mechanisms are included in the
terminal hardware making it impossible to tell whether it was opened
to access the PCMCIA slot. There is no cryptographic or other
authentication of the code that is to be loaded, just some very simple
integrity checking (checksum or CRC presumably) of the binary.
Evidently, Diebold decided to make field upgrades simpler at the cost of
providing little to no protection against abuse.
It is well understood by security experts that preventing physical access
to computers is the first step in securing them. Unfortunately, election
officials and polling place workers are not typically security experts and
the access to the terminals is not strictly limited. In fact, they are
regularly taken to polling places (schools, churches, etc.) or to the homes
of polling place supervisors several days in advance of an election. In
addition, because the bootloader code can be modified, a clever attacker
could install code that survived any number of software upgrades, waiting
to be activated at the proper time. Diebold even conveniently provides an
external switch, accessible to a voter, that could be used to trigger the
dormant code.
This is not the first time that Diebold security has been
found to be woefully
inadequate and, once again, the company does not seem to understand the
problem. A spokesman for Diebold, David Bear, had this to say:
For there to be a problem here, you're basically assuming a premise
where you have some evil and nefarious election officials who would sneak
in and introduce a piece of software, I don't believe these evil elections
people exist.
Bear tries to deflect the criticism by claiming that it is only election
officials who could make these changes, but there are actually a huge
number of ways that it could happen. Simply showing up at the county
clerk's office in an official looking Diebold uniform would probably be
enough to get access to the machines in many areas.
Unfortunately, it is not just Diebold that misses the implications of this
kind of threat; various election officials, many of whom spent a great deal
of taxpayer money buying Diebold voting equipment, also downplay the threat.
Several elections, including a primary last Tuesday in Pennsylvania, are going
on as scheduled using the equipment, seemingly without any concern that
the terminals could have been tampered with.
For the most part, this is a hardware problem: the Diebold terminals
were not designed to be tamper-proof, instead they were designed to be
easy to access. This is something for the various advocates of other
voting technologies, including open
source voting, to consider. Having the source code to the binary that
is supposed to be installed is not sufficient, there needs to be some
way to ensure that it is the software that is currently running. Having a way
to resist tampering with the hardware and to detect attempts to tamper
with the hardware are also mandatory for any voting system.
There seems to be a great deal of resistance to the idea of having a paper
trail that can be verified by the voter as a backup system, at least from
the voting equipment vendors, but this would seem to be the most sensible
check on the proper functioning of the equipment. It still provides the
instant gratification of vote counts that seem to be required, but also
allows for an auditable recount should one be necessary.
The lackadaisical
approach to security and the resistance to an auditable paper trail might
lead a cynical person to believe that those in power like things exactly
as they are.

Multiple vulnerabilities in the Linux have been found.
- An error in the Stream Control Transmission Protocol (SCTP) code that
uses incorrect state table entries when certain ECNE chunks are received in
CLOSED state, could be exploited by attackers to cause a kernel panic via a
specially crafted packet.
- An error exist when handling incoming IP-fragmented SCTP control
chunks, which could be exploited by attackers to cause a kernel panic via a
specially crafted packet.
- Linux SCTP (lksctp) allows remote attackers to cause a denial of
service (infinite recursion and crash) via a packet that contains two or
more DATA fragments, which causes an skb pointer to refer back to itself
when the full message is reassembled, leading to infinite recursion in the
sctp_skb_pull function
- Linux SCTP (lksctp) allows remote attackers to cause a denial of
service (deadlock) via a large number of small messages to a receiver
application that cannot process the messages quickly enough, which leads to
"spillover of the receive buffer."
- A vulnerability has been identified due to an input validation error
when processing arguments containing backslash ("\\") characters passed to
certain commands (e.g. "cd"), which could be exploited by authenticated
attackers to escape chroot restrictions for a CIFS or SMBFS mounted
filesystem.

| Description: |
Several buffer overflows have been discovered in libgd's PNG handling
functions.
If an attacker tricked a user into loading a malicious PNG image, they
could leverage this into executing arbitrary code in the context of
the user opening image. Most importantly, this library is commonly
used in PHP. One possible target would be a PHP driven photo website
that lets users upload images. Therefore this vulnerability might lead
to privilege escalation to a web server's privileges.
Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and
earlier may allow remote attackers to execute arbitrary code via malformed
image files that trigger the overflows due to improper calls to the
gdMalloc function. |

Kernel development
Brief items
The current stable 2.6 kernel is 2.6.16.16,
released on May 10. It
contains yet another security fix; this one is for
a denial of service problem in the filesystem
locking code.
The current 2.6 prepatch is 2.6.17-rc4, released on May 11. It is
almost entirely made up of fixes; Linus says "this is the time to
hunker down for 2.6.17." The long-format
changelog has the details.
Nearly 100 patches have been merged into the mainline git repository since
-rc4 was released; they are almost all fixes.
The current -mm tree is 2.6.17-rc4-mm1. Recent changes
to -mm include CacheFS, a
patch making address space operations constant, the deprecation of smbfs
(see below), the per-task delay
accounting patches, eCryptfs, and klibc, a
lightweight C library for use in initramfs code.

I think actually we're heading towards needing Linux V2 - the
rewrite. It seems that fixing simple bugs cause[s] other bugs, and
that means we're heading into a maintainability nightmare.

The venerable smbfs code allows Linux systems to mount filesystems exported
via the SMB protocol. It thus can be used for accessing files exported
from a Windows system. This filesystem has seen a lot of use over the
years, but has, in recent times, been overtaken by the newer CIFS
filesystem. At this point, CIFS receives almost all of the developer
attention, and most users have (or, at least, should have) moved over.
As an example of the difference in how smbfs and CIFS are maintained,
consider the 2.6.16.11 stable
kernel update, which contained a fix for a security problem in the CIFS
code. Though CIFS has its roots in smbfs, nobody was paying enough
attention to realize that smbfs might suffer from the same vulnerability.
Thus, while 2.6.16.11 fixed the CIFS problem on April 24, the matching
smbfs fix (which forced 2.6.16.14), did not appear until
May 4, eleven days later. In the mean time, smbfs was vulnerable to a
known bug, for anybody who thought to look for it.
The 2.6.17-rc4-mm1 kernel recognizes the unmaintained nature of smbfs with
a patch marking it as being deprecated and slated for eventual removal.
All remaining users are encouraged to move over to the CIFS implementation
instead. For some users, the end has come sooner - the Fedora Core 5
kernel already does not support smbfs. Since there
is an alternative in the kernel and ready to go, this migration should not
be a big problem.
It is a nice scenario, but there is one little problem: the CIFS code
cannot work with Windows 95 and Windows 98 systems. Without
smbfs, Linux users will not be able to mount shares exported from hosts
running those old versions of Windows. Some observers have commented that
those versions of Windows are too old to support, but Linus isn't buying it:
But we do _not_ drop features just because they are deemed
"unnecessary". As long as somebody actually _uses_ smbfs, and as
long as those users are willing to test and perhaps send in patches
for when/if it breaks, we should not drop it.
The word from Andrew Morton is that Windows 9x support for CIFS is in the works,
and should, with luck, by ready in time to go into 2.6.18. If things
happen that way, then the 2.6.18 kernel might just include a deprecation
notice for smbfs, and smbfs could be marked "broken" by the end of the
year. Anybody still using smbfs should consider themselves warned.

Jeff Garzik has recently
let it
be known that he has merged a large set of patches to the serial ATA (SATA)
subsystem. Says Jeff: "
If all goes well, this update should improve
error handling, solve several outstanding, difficult-to-solve bugs, and
provide a good foundation for adding some nifty features in the
future." His plans are to get the new code merged into the 2.6.18
kernel, once that cycle begins. The result could be a significantly
different experience for Linux SATA users, some of whom have been fighting
problems for some time.
The patches themselves have been posted to the linux-ide list. It makes
for some imposing reading: they are 122 patches, divided into eleven sets.
This flood of code is primarily the work of Tejun Heo, though Jens Axboe
and Albert Lee have also played a significant part. In brief, what is
coming is:
- A completely reworked libata error handler. This code makes up about
a third of the total set of patches, and cleans up a lot of things.
It creates a modularized error handling mechanism which allows
low-level drivers to intervene or change the response at various
points in the process. Memory needed for error handling is now
allocated ahead of time, minimizing the possibility for complications
just when things are already going wrong. There is a special circular
buffer set aside for recording errors; this information is used, for
example, within the recovery code to determine that the error rate is
too high and that transmission speed should be lowered.
The result of all this work should be a much more robust SATA
subsystem which can recover from a much wider range of errors.
- A new programmed I/O loop which uses interrupts, rather than older
method of polling the controller from a kernel thread. In cases where
programmed I/O is needed, the new code should be more efficient.
- Native Command Queuing (NCQ). NCQ is the SATA version of tagged
command queuing - the ability to have several I/O requests to the
same drive outstanding at the same time. NCQ eliminates the idle time
between when one command completes and the next is issued, but the
real advantage is with the ordering of operations. The Linux block
I/O subsystem attempts to issue block I/O requests in an efficient
order, but it must use a certain amount of guessing, since there is no
way to know how the blocks are really organized on the disk. But the
drive itself knows very well where each block lives, so it is well
placed to optimize the ordering of requests. The result can be a
significant improvement in performance.
The Linux NCQ implementation can have up to 32 operations outstanding
at any given time - though both the drive and the host controller can
reduce that number. Your editor is not aware of any relative
performance benchmarks which have been posted.
- Hotplug support is another large piece of the patch set. With these
patches in place, the SATA layer can deal with drives which come and
go - as long as the underlying hardware was designed with hotplugging
in mind. There is also a "warmplug" capability for more limited
hardware, where a system user can request the addition or removal of
drives on a running system.
- A new layer (called "ata_link") has been added to libata; ata_link
handles the physical-layer connection to the drives. The main
motivation for ata_link appears to make it possible to support SATA
port
multipliers, which expand the number of drives which can be
plugged into a system. The current port multiplier code supports the
"frame information structure" switching mode, whereby all connected
drives can be active simultaneously. For now, it only works
with the sil24 driver, but support for others will certainly come.
Most of this code has been under development and discussion for some time.
The sense (among its developers) is that the bulk of it is ready to go into
2.6.18, though the hotplug, ata_link, and port multiplier code may have to wait for another cycle. Andrew
Morton has expressed some concerns about
merging all of this code when a rather long list of SATA-related bugs
remains outstanding; Jeff responded that
this code will fix many of the bugs and make tracking down many of the rest
easier. So, chances are, 2.6.18 will include a much-improved SATA layer.

There are a number of virtualization technologies available for Linux, some
of which have gained a lot of headlines in the last year or two. One of
the oldest and most interesting, however, maintains a lower profile.
User-mode Linux
(UML), first implemented by Jeff Dike, takes a unique
approach to virtualization. A UML kernel runs within a process on a normal
Linux host; it is, essentially, a special port of the kernel designed to
run within another Linux system. As a result, a UML system looks like a
series of ordinary processes on the host; it can be managed (and debugged)
like any other process tree.
UML can be somewhat intimidating at first. It brings a new set of acronyms
and a whole set of complex configuration options. As with many parts of
Linux, the documentation available for UML has not always been everything
one might want. So the publication of User Mode Linux,
written by the same Jeff Dike, is a welcome event. This book is part of
the Bruce Perens Open Source Series, meaning that it will be released under
the Open Content License later this year. For now, however, the book must
be obtained the old-fashioned way. For those interested in UML, it should
be a worthwhile investment.
The book adopts a tutorial format, starting with an introduction to UML and
virtualization in general. It provides a walk through of a simple UML
session, then introduces virtual disks and network interfaces.
The core of the book is a series of chapters on managing UML and connecting
it with the host system (and other UML instances). So there is a chapter
on filesystem management, including details on how to provide restricted
access to filesystems on the host. A detailed chapter on networking has
been provided. UML has several possible network transports which can be
used to create isolated networks for UML systems or to connect those
systems to the wider world; this chapter covers them all and provides
guidance on how to choose between them. Then there is a chapter on the
management interface to UML.
The final set of chapters looks at configuring UML for specific tasks.
Chapter 11 talks about building UML from source. In your editor's opinion,
that chapter comes a little late; everything to that point has simply
assumed that UML is already available on the reader's system. Some
distributions have UML packages, but others do not. So some early guidance
on how to build a UML system and create an initial filesystem for it to
boot from would have been nice. The book finishes with some talk of the
(ambitious) future plans for UML and a couple of reference sections.
There is no clear information on just which version of UML is covered - an
unfortunate omission. The sample boot output in the introductory chapter
shows 2.6.10 and 2.6.11-rc kernels.
Minor quibbles aside, it is hard to find much to complain about in Jeff's
book. It provides a much-needed reference for an important Linux
virtualization mechanism. There are a number of possible uses for UML,
including kernel development, server consolidation, embedded systems
development, experimenting with different distributions, or the simple joy
of running a large cluster on one's laptop. Regardless of their goal, UML
users will find this book to be a worthwhile addition to their shelves.

Multiarch is a concept that involves the ability to run binaries compiled
on one architecture on machines with a different architecture.
For example, an amd64 system Linux system would be able to run the
same binary programs that run on an i386 Linux system. This idea has been
talked about by a few Debian developers for at least a couple of years.
This week Matt Taggart posted an update on
the Debian-devel mailing list, with a pointer to a wiki where information and
status is being tracked, and a pointer to a report
(PDF) entitled Multi-Arch Implementation Strategy,
prepared for HP by Canonical Ltd. What follows is a summary of the
report.
The report looks at various ways to extend Debian (and derived systems) to
provide multiarch support. Implementation strategies will be tested
during the upcoming Ubuntu Eft development cycle and, hopefully, be
deployed in the Debian etch release.
The primary problem with multiarch support is in shared libraries normally
located in the /usr/lib directory. These libraries are shared by many
binary programs and they may also contain architecture specific
information. For example, and an AMD64 library would specify such things
as address space, calling conventions, word and data sizes, and other
information that would not allow a program to load on i386 system.
The currently favored solution is to move the libraries into arch-named
subdirectories under /usr/lib. This would allow the binary package to link
to the correct architecture specific library.
Another problem is in the architecture dependent binaries in /usr/bin and
/usr/sbin. An openssl binary complied for the i386 architecture might run
quite well on an amd64 system, but that amd64 system can't have the
native version of openssl installed at the same time unless the system
administrator put the package in /opt or /usr/local. The proposed location
for all architecture-independent binaries is under /usr/share.
When creating shared libraries, developers should keep separate the
architecture-dependent files from the architecture-independent files and
avoid hard coding the paths to architecture-dependent files. This will
avoid naming conflicts, save space, and allow the architecture-dependent
files to moved or renamed as needed.
Ideally a multiarch system should not need special packages and should not
waste disk space unnecessarily. Package maintainers and system
administrators should not need to know more or do more to make the system
work. Configuration files should be easily shared by multiple systems.
In the long term upstream developers will need to be retrained to write
code that can be more easily shared. In the short term, chroots should be
used when installing software from multiple architectures. Environment
packages, multiple binary production and automated package rewriting could
also help in the short term.
An attempt to get OpenOffice.org 2 running on a multiarch system was used
as a feasibility study. While it would be highly desirable to have a
multiarch OOo, it was not designed that way and numerous problems were
encountered in the process. Ultimately they recommend that multiarch
support be built into the package manager. While rewriting massive amounts
of existing code is not really feasible, new developers would do well to
keep multiarch guidelines in mind when creating new packages and
libraries.

"
Because the OLPC spec calls for 128MB of system DRAM and Puppy Linux
weighs in at only around 60MB of memory footprint, [Puppy founder Barry]
Kauler and a number of Puppy enthusiasts believe it is the right distro for
the project. "Puppy is designed for this kind of situation from the
ground-up," writes Kauler. "Extremely fast, very small footprint, a full
set of applications, limited writes to flash [storage memory] to extend its
life indefinitely. There are no compromises -- if you have read commentary

Distribution reviews
NewsForge
hears
from an Arch Linux fan. "
Arch Linux is a bleeding-edge
distribution built from the ground up using Linux From Scratch as a base
with a driving philosophy: keep it simple. However, I've come to learn that
simple doesn't mean easy. The Arch Linux definition of simple means that
GUI tools should not hinder the full capability of individual software
packages. This philosophy engenders a minimalist approach, and Arch clearly
defines itself as targeted to "competent Linux users." However, don't let
this phrase scare you off. There exist plenty of well-written documents on
the ArchLinux wiki and forums to help you out, as well as a wonderful
community to aid and assist you if all else fails."

plows
through a manual Gentoo install. "
Installing Gentoo using the
manual method described in the Gentoo Handbook is, to put it bluntly, a
royal pain. It's a good hands-on experience if you're looking to learn
about the nitty-gritty of system configuration, but a lousy way to install
Linux quickly, and almost certain to be intimidating for anyone who's not
well-versed with Linux already."

Ututo-e. "
A year ago, I reviewed Ututo-e, an Argentinian
distribution based on Gentoo. Ututo-e is known mainly as the only GNU/Linux
distribution endorsed by Richard Stallman and the Free Software Foundation
(FSF). This endorsement is based on the fact that Ututo-e, in the words of
Peter Brown of the FSF, "makes a commitment to follow the philosophy of the
FSF as to what makes a distribution ethically free software." Last year,
this endorsement seemed premature, because Ututo-e, while promising in some
places, was buggy in many more. A year later, the 2006 release of Ututo-e
is more polished, especially in its desktop and selection of administration
tools, but its English version still falls below the standard of leading
distributions such as Debian or Fedora Core."

Development
The Bon Echo Alpha 2 release of the Firefox 2 web browser
was announced
this week. We
looked at
the alpha 1 release in March.
Bon Echo Alpha 2 is the second developer milestone on the path to
Firefox 2. This milestone is focused on testing the core functionality
provided by many of or new features and changes to the platform
scheduled for Firefox 2.
New features in this version, which include some of the alpha 1
additions, are:
- The default new window behavior opens a new tab, not a new window.
- Each tab now has its own close button.
- Text boxes now feature inline spell checking, errors are underlined in red.
- The browsing session is automatically restored in the event of a crash.
- The Google and Yahoo search boxes have automatic search suggestions.
- Support for the Sherlock and OpenSearch engines has been added.
- There is a new search plugin manager for configuring search engines.
- Previewing and subscribing to web feeds has been improved.
- There is a new
Microsummaries feature for adding real-time information to bookmarks.
- A new Add-Ons manager is available for managing extensions and themes.
- Extension system updates improve security and extension localization.
- SVG text on a path support has been added.
More details on this version are available in the
release notes.
Your editor decided to give Bon Echo Alpha 2 a test drive in a real-world
situation, working on this week's LWN edition.
Installing the browser involved downloading, uncompressing and extracting
a tar file, then running ./firefox in the resulting Firefox
directory. The older version of Firefox had to be shut down before
Bon Echo A2 would start.
The first impression was that the default fonts were somewhat ugly.
Font selection is a personal choice, and it was easy to use the usual
Edit/Preferences window to select the more pleasing
Bitstream Vera Sans font.
Editing an LWN article (see the screen shot) involves using several
HTML text boxes, this activated the inline spell checking feature.
The red underlining is not terribly hard on the eyes, and it
shows up words that are suspect. Surprisingly, Firefox is not in
the spelling dictionary. Many, but not all, html tags also show up as spelling errors. A useful addition would be the underlining of html
code in another color.
An odd behavior was observed when typing characters into the smaller
text box that is shown in the example screen shot. Using the left arrow
key to move the cursor worked as expected, but pushing the right arrow
key, or the up and down arrow keys caused the window to refresh, and
focus was moved to the lower and larger text box. Sometimes, but not
always, clicking the mouse in one box would also cause a similar refocus.
Clearly, there is still a bug in the code, one should expect that with
early releases.
On the other hand, earlier versions of Firefox have had problems
involving the loss of text that was yanked into the mouse buffer,
that behavior seems to have been improved.
The new search engine features seem to be handy on the first try,
typing a word in the search engine field at the top right side of the
screen causes a pop-up window with related search topics to show up.
The search engine window also has a new arrow that activates the search
engine configuration tool.
Despite a few odd behaviors, Bon Echo Alpha 2 was able to handle
the exercise of editing and writing LWN articles for several hours
without crashing.
There are a few
known issues with this release, and probably a few more which will
show up now that the software is available for general testing.
Nonetheless, some useful new capabilities are being added to Firefox.
Firefox should hold its position as the default Linux browser for some
time.

The

increasingly often, described as the audio and video support system for

Christian Schaller has posted
a lengthy

So I hope that
interested people in the KDE community agrees with my analysis and starts
working on Qt-style bindings for GStreamer, and as a result Phonon falls by
the wayside. If not, well hopefully we will be able to cooperate on some of
the lower level issues in the desktop, like improved driver handling
through HAL for instance as the minimum." Multimedia support is not
a solved problem on Linux, so it will be interesting to see how this
discussion proceeds.

they will change the world." (Thanks to John Rigg).

David A. Wheeler presents a new essay entitled
High Assurance (for Security or Safety) and Free-Libre / Open Source Software (FLOSS).
"
This paper discusses some relationships between high assurance software (for security or safety) and free-libre / open source software (FLOSS). In particular, it shows that many tools for developing high assurance software have FLOSS licenses, by identifying FLOSS tools for software configuration management, testing, formal methods, analysis implementation, and code generation. However, while high assurance components are rare, FLOSS high assurance components are even rarer. This is in contrast with medium assurance, where there are a vast number of FLOSS tools and FLOSS components, and the security record of FLOSS components is quite impressive. The paper then examines why this is the circumstance."

| Phonon and gstreamer (KDE developer response) |
| Date: |
| Fri, 12 May 2006 12:04:18 -0400 |
I saw with interest your article on the objections to Phonon by a gstreamer
developer.
I'm a KDE developer myself, and I co-develop the JuK application included with
KDE. For a couple of years JuK has supported gstreamer output, so I think I
have a fair amount of knowledge regarding the interaction of KDE and
gstreamer.
So here are my comments:
Phonon is designed to solve 2 major issues:
1. A simple API for basic multimedia tasks. i.e. playing a song, playing a
video, maybe visualization. Nothing complex, but enough to make it easy to
add basic multimedia support to applications.
2. Do all of this in a binary compatible fashion.
What does this stuff about binary compatibility mean? Well, basically that
the set of libraries that KDE distributes for programmers to develop against
must be binary compatible. That is, if you compile a KDE game against
kdelibs 4.0, and then upgrade kdelibs to 4.1, your KDE game should work with
no recompilation required.
Multimedia features should be a part of kdelibs, as they will be shared
between many different applications. So, the KDE multimedia framework must
be binary compatible as well.
Why wasn't this an issue with KDE 3? Well, that was because we adopted aRts
as the standard multimedia framework for KDE 3, and made sure it was binary
compatible as well. We could do this because we controlled aRts. Needless
to say, this didn't turn out so well. The aRts developer eventually grew
tired of maintaining aRts. None of us were really familiar enough with the
code to add new features (although we managed to get some small stuff done),
so aRts just rotted.
We weren't going to repeat that mistake for KDE 4. People have mentioned that
gstreamer is not going to be abandoned, as it has much more developer
traction than aRts ever did. But that's not the point. People don't realize
that we would have to choose a specific release branch of gstreamer should we
adopt gstreamer. In other words, we're not just stuck with gstreamer, we're
stuck with gstreamer 0.10 (binary compatibility!).
This would be fine (in theory) if gstreamer 0.10 were to be the branch that
features were developed against for the lifetime of KDE 4. But this is
impractical for the gstreamer developers. They would be tied to our release
schedule. They wouldn't be able to correct design flaws with
binary-incompatible releases like they have with 0.8 and 0.10 releases.
So, it is obvious they would continue to improve gstreamer, probably with 0.12
and 0.14 in the KDE 4 timeframe. But we would still be stuck requiring 0.10.
And then perhaps 0.12 was such a quantum leap above that we decided to add
support for it to kdelibs. Now we require two separate gstreamer versions to
be installed.
Now, gstreamer has excellent provisions for installation of different
versions. But that is not what I would call user friendly. Plus it doesn't
account for the case where users upgrade from gstreamer 0.y to 0.y+2 and
remove 0.y, and unintentionally completely break their KDE installation.
So if we just rely on gstreamer 0.10, now we're stuck with an abandoned code
base, which KDE developers are unfamiliar with. Does this sound familiar to
anyone? ;)
The gstreamer developer recommended developing a Qt/KDE layer directly on top
of gstreamer. This is impractical as well. In fact, we have done it before.
We had a very nice wrapper over gstreamer 0.6 that we used for JuK at one
point. But when 0.8 came out, enough of the gstreamer design had changed
that the gstreamer 0.6 bindings were useless, and couldn't be simply "ported"
over. This left JuK in a bad state, relying on an obsolete gstreamer, until
we finally gave up waiting for bindings, and added the bare minimum of
gstreamer 0.8 support. We also had to do the same thing during the 0.8 to
0.10 transition thanks to changes in the synchronous handling of gstreamer
events.
This isn't to blame the gstreamer developers: Both gstreamer upgrades were a
definite change for the better. But the problem is that they were still a
definite change. We won't be able to keep the Qt/KDE gstreamer bindings up
to date, not to mention binary compatible, without limiting the scope of the
API that we wrap. In fact, Phonon is about the extent of the amount of
wrapping we'd be able to do.
So basically we have to have some sort of framework to isolate most of KDE
from changes in the underlying multimedia stuff. (Applications that require
more than Phonon can provide would just have to rely on the appropriate
backend directly, but then they're not in kdelibs either). Once we've
developed a framework that can insulate against API changes across gstreamer,
it's not hard to see how to extend that to other backends.
I've railed on about this (slightly less politely) on my blog at
http://grammarian.homelinux.net/~mpyne/weblog/kde/phonon-...
I think this would be a great explanation for a front page article (sans the
blog link to my home computer ;), as I have seen a lot of misunderstanding
regarding Phonon this morning browsing across the flamewar.
Thanks for the great coverage of all things Linux:
Regards,
- Michael Pyne
