The Novell Partner Linux Driver Process

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.

Java becomes more distributable

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.

Waiting for Rockbox 3.0

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:

  • Strict time-based releases, as characterized by projects like GNOME or OpenBSD. Some projects would appear to employ a low-stratum network time protocol server to time their releases to the millisecond. This approach solves the "when do we release?" question, but it will not be suitable for all projects. It would appear to work best when the project is made up of many independent components, any of which can be dropped (or kept at an older version) if they are not ready at release time.

    Interestingly, the Linux kernel has moved slowly toward this mode over time with its 6-8 week process.

  • The "when it's ready" approach. Waiting until no (known) critical-level bugs remain can lead to stable releases, but on an indeterminate schedule. Debian's stable releases highlight both aspects of this approach. The older (2.4 and prior) kernel model also worked this way.

  • Separate stable and development branches. In theory, this approach allows development to go forward without disturbing the branch intended for the stable release. The pre-2.6 kernel sort of used this approach, except that the development branch was not created until a number of stable releases and updates had gone out. The Mozilla Foundation has used an approach like this as well. The problems here include a certain tendency for developers to go play in the unstable branch and not work on fixing bugs and difficulties in propagating important fixes between the two branches.

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.

Open Content III: the code

May 16, 2006

This article was contributed by Glyn Moody

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

Diebold election insecurity systems

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.

cpio: arbitrary code execution

Package(s):cpio CVE #(s):CVE-2005-4268
Created:January 2, 2006 Updated:March 17, 2010
Description: Richard Harms discovered that cpio did not sufficiently validate file properties when creating archives. Files with e. g. a very large size caused a buffer overflow. By tricking a user or an automatic backup system into putting a specially crafted file into a cpio archive, a local attacker could probably exploit this to execute arbitrary code with the privileges of the target user (which is likely root in an automatic backup system).

libgadu: memory alignment bug

Package(s):libgadu CVE #(s):CAN-2005-2370
Created:July 29, 2005 Updated:June 25, 2007
Description: Szymon Zygmunt and Michal Bartoszkiewicz discovered a memory alignment error in libgadu (from ekg, console Gadu Gadu client, an instant messaging program) which is included in gaim, a multi-protocol instant messaging client, as well. This can not be exploited on the x86 architecture but on others, e.g. on Sparc and lead to a bus error, in other words a denial of service.

libgd2: buffer overflows in PNG handling

Package(s):libgd2 CVE #(s):CAN-2004-0990 CAN-2004-0941
Created:October 29, 2004 Updated:June 28, 2006
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.

squirrelmail: multiple vulnerabilities

Package(s):squirrelmail CVE #(s):CVE-2006-0188 CVE-2006-0195 CVE-2006-0377
Created:February 28, 2006 Updated:June 8, 2006
Description: Webmail.php in SquirrelMail 1.4.0 to 1.4.5 allows remote attackers to inject arbitrary web pages into the right frame via a URL in the right_frame parameter. NOTE: this has been called a cross-site scripting (XSS) issue, but it is different than what is normally identified as XSS. (CVE-2006-0188)

Interpretation conflict in the MagicHTML filter in SquirrelMail 1.4.0 to 1.4.5 allows remote attackers to conduct cross-site scripting (XSS) attacks via style sheet specifiers with invalid (1) "/*" and "*/" comments, or (2) a newline in a "url" specifier, which is processed by certain web browsers including Internet Explorer. (CVE-2006-0195)

CRLF injection vulnerability in SquirrelMail 1.4.0 to 1.4.5 allows remote attackers to inject arbitrary IMAP commands via newline characters in the mailbox parameter of the sqimap_mailbox_select command, aka "IMAP injection." (CVE-2006-0377)

Kernel development

Brief items

Kernel release status

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.

Quotes of the week

I could set up a nice business here selling second-hand brown paper bags.

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.

On the future of smbfs

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.

Big serial ATA changes

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.

Book Review: User Mode Linux

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.

[Book cover] 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.

Debian multiarch support

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.

Debian etch transitions

Martin Michlmayr reports on possibility of moving to GCC 4.1 for the etch release. "In summary, there are ~140 bugs that need to be fixed in the next few weeks.

Michael Koch looks at a GCJ 4.1 transition. "The Debian Java Team wants to switch the default version gcj/gij to point to the according 4.1 version. After that is done all GCJ 4.0 packages will be removed from unstable. Most packages should just need a simple rebuild. Packages building a native JNI library will need some manual action as long as gcc-4.1/g++-4.1 are not the default compilers. The problems are JNI include files which are located in a compiler specific directory. To make your packages build please add -I/usr/lib/jvm/java-gcj/include to your compiler flags."

Puppy Linux founder comments on the OLPC project (DesktopLinux.com)

DesktopLinux looks at the suitability of Puppy Linux for the One Laptop Per Child project. "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 about the OLPC project from various sources, you would think that an operating system and applications squeezed into such a minimal system would be severely compromised. Not so.""

My desktop OS: Arch Linux (NewsForge)

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."

Ututo-e: 'The only free distribution' revisited (Linux.com)

Linux.com reviews 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

A test drive of Firefox Bon Echo Alpha 2

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. [Firefox Bon Echo a2]

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.

A GStreamer developer on Phonon

The Phonon multimedia framework is, increasingly often, described as the audio and video support system for KDE 4. In what may be a sign of things to come, GStreamer developer Christian Schaller has posted a lengthy article on why he thinks Phonon is a bad idea. "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.

Version 2.3 Beta of FCKeditor has been announced. Here are the changes: "Extremely Fast Loading! The editor loads now more than 3 times faster than before. Many points of its core have to be touched; this is why it is a "Beta", but it is quite stable. Many new features: nested context menus, "maximize" and a few interface enhancements. Important bugs have been fixed, some of them regarding security issues. So, upgrade is highly recommended."

Office ODF Support: Bad for Business!? (Linux-Watch)

Steven J. Vaughan-Nichols analyzes some corporate FUD about adding OpenDocument Format support to Microsoft Word. "You've got to love Microsoft's sloppy way of opposing Linux and open-source some days. In Microsoft's latest FUD move, as reported in Linux Pipeline, Melanie Wyne, executive director of the ISC (Initiative for Software Choice), has accused the Massachusetts Information and Technology Division of having "a biased, open source-only preference policy." Their crime? Requesting a plug-in for Microsoft's Office Suite that can save and read to the ODF (OpenDocument Format). Horrors!"

Linux System Administration: Growth in the Enterprise (Linux Journal)

Linux Journal looks at an online Linux training course offered by SpiderTools of Trout Creek, Montana. "Linux has gained market share quickly and many companies say they cannot find enough people to handle the work. So, they attempt to convert Microsoft trained engineers to work on Linux. That confirms a statement Mike Weber made to me when he said, "We see a number of young administrators who have new jobs that require a larger skill set than what they had to get the job". When administrators suddenly find themselves needing to perform tasks on a new Linux server, Mike Weber's team can provide rapid training. According to Mike, "the availability of broadband has allowed people to connect and use interactive multimedia for training now. We have students all over the world who can access our training because of broadband."

India lays down 'open' challenge (BBC)

Here's a BBC article from a columnist who thinks that Asia will come to dominate the free software community. "Free software provides a bridge between the affluence of the West and the poverty of most of the world's population, and amounts to a massive flow of intellectual capital into the developing world. And as they reshape it to meet their needs it will stop being just another US import and become a resource that can be used in brand new ways. Once the people on the receiving end make it their own they will change the world." (Thanks to John Rigg).

Out the Window (WSJ)

A Wall Street Journal reporter tried out six Linux distributions on his laptop and reported on the results. "For me, though, using the Linux systems didn't make sense. I often send documents and spreadsheets between my home PC and the one at work, which uses Microsoft Office. And the files are sometimes complex. Meanwhile, for both personal and professional computer use, I want access to all multimedia functions. While solutions may exist to almost every problem I encountered, I was willing to invest only a limited amount of time as a system administrator. Claims by some Linux publishers that anybody can easily switch to Linux from Windows seem totally oversold."

High Assurance and Free-Libre / Open Source Software

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."

Letters to the editor

Phonon and gstreamer (KDE developer response)

From:  Michael Pyne <michael.pyne-AT-kdemail.net>
To:  letters-AT-lwn.net
Subject:  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
