LWN.net Weekly Edition for May 19, 2005A call for an open media gadgetYour editor, recently faced with some long flights, went out and bought himself a portable media player. Despite certain, predictable marital problems caused by the acquisition of yet another expensive electronic toy, the new device has been a great success. It is Linux friendly, plays Ogg files, sounds good, and makes it possible to carry vast amounts of music in a shirt pocket. Since your editor is a fan of live music, he has been especially pleased by the combination of the player and the vast library of concert recordings which is downloadable - with the artists' permission - from archive.org.On the other hand, this device has its annoyances. It boots slowly. The user interface has clearly not been through a serious usability program. The device has a beautiful color display, but most of the space is wasted with silly decorations so that song titles must be scrolled. There are no games to keep the kids happy. And so on. Wouldn't it be nice to be able to go in and hack on the code so that this hardware, which is so full of potential, could be enjoyed fully? Efforts like the open graphics project seek to push forward the state of free graphics through the creation of entirely open hardware. That project is worthwhile, and we wish its developers the best of luck. But here is a question worth asking: might there not be value in the creation of an open media gadget? One could easily put together a wishlist of features: a nice display, substantial internal storage, good analog-to-digital and digital-to-analog hardware, an FM tuner, a low-power FM transmitter, an integrated camera, Bluetooth and/or WiFi networking, etc. But gadgets already exist with most or all of those capabilities. What's missing is this: the platform should be based on Linux, all of the source for the base system should be available, and it should be easy to install new software (and replace existing software) on the system. This gadget should not just tolerate having its operating software ripped out and replaced; it should be designed with that in mind from the beginning. A solid, open platform can inspire a great deal of creativity in the wider development community. Can you imagine what sort of community might gather around a media gadget which is not only open, but which actively encourages its users to hack on it? This device would rapidly develop capabilities unimagined by its creators; if a way could be found to produce it at a reasonable price, chances are that it would be a raging commercial success. Your editor - once his credit card has been returned to him - would gladly buy one. Thanks to over twenty years of work from the free software community, many of us can do our core computing with entirely free systems. But this freedom has not yet extended into many of the other computers that we use every day. Maybe, someday, the consumer electronics industry will realize that, while it makes great hardware, it can do better by letting its customers create much of its software for it. But, while we're waiting, perhaps there are some people with the same sort of drive and skills as shown by the Open Graphics Project who would like to show the industry how it can be done?
A turning point for shorewallShorewall is a front-end to the Linux netfilter system which makes it (relatively) easy to set up and maintain a firewall. It has a dedicated user community which appreciates Shorewall's flexibility and documentation, along with the ability to secure a system with a minimum of hassle. The current release is 2.2.4.Unfortunately, that may be the last release for a while; Shorewall maintainer Tom Eastep has announced that he will no longer work on the project. Shorewall, it seems, has fallen victim to a common problem with smaller projects: developer burnout. Mr. Eastep has concluded that Shorewall development takes more of his time (and health) than he can afford to give. There appears to be a couple of problems in how Shorewall is developed. The first is that nobody has stepped up to take on a significant part of the load, leaving Mr. Eastep to do all of the work himself:
Unlike the originators of other successful open source projects, I
have not been able to attract a core of people who believe in
Shorewall and who are willing to make sacrifices to ensure it's
success. That is my weakness and I accept it. But is means that I
have been left with trying to develop, document, and support
Shorewall almost single-handedly. I cannot do it any more.
Without having followed the development process for this project, we would be ill-advised to say why things turned out this way. It could be that the Shorewall community did not feel the need to contribute to the project, or it could be that Mr. Eastep, in one way or another, discouraged that sort of involvement. But any project which is dependent on a single person in this way will always be at risk. Mr. Eastep also notes:
And I just cannot deal with the support and documentation
frustration any more -- support, the documentation and the web site
consume an order of magnitude more of my time than does Shorewall
development.
He was apparently unwilling to solve this problem the way many free software developers do: simply ignore support and documentation altogether. The documentation for Shorewall is extensive, to say the least; it clearly took a lot of time. Likewise with support; a reading of the Shorewall mailing list shows Mr. Eastep doing his best to answer most of the questions that were asked. It is not surprising that he got tired of carrying that load. Shorewall is free software, and it almost certainly will not die. There are already some signs that members of the user community are beginning to step up to help ensure that the project continues. This is, of course, one of the strengths of free software; had Shorewall been proprietary, it would now be dead. But the other side of this coin is that the user community has to take an interest in the software it depends on. If users do not come forward over time to help with programming, documentation, and support, they may find themselves having to do it in a hurry when the primary maintainer departs. (Thanks to Matt "Cyber Dog" LaPlante for the heads-up).
Apple and KHTMLApple's use of KHTML and KJS in WebCore, (part of Safari) was widely hailed at the time as a success story between open source and a commercial software company. That was two years ago. Recently, Apple announced that it had passed the Acid2 Test, which prompted users to start wondering when Konqueror would start being Acid2-compliant. This, in turn, sparked a few developers to clarify that Apple's changes to KHTML and KJS were not necessarily in a form that was easily digestible by the KHTML and KJS teams -- in fact, Apple's changes in some parts, using OS X API, make the code more or less incompatible with KHTML and KJS. While Apple is complying with the license (LGPL), it would seem that Apple was not going much further than required by the LGPL. After it became public that the relationship between KHTML and WebCore was not a symbiotic success story between open source and Apple, it quickly turned into a "vs." story in the mainstream IT media, like CNET's "Open-source divorce for Apple's Safari." While the headline may be catchy, it seriously overstates the situation and misses some of the finer points in the relationship. In order to sort through some of the mess to present a more realistic picture, we tried to get folks from both sides to comment. Apple did not respond to a request for comment, but KDE developer Harri Porten was kind enough to respond to questions from LWN. The first question we posed to Porten was what Apple could do in order to make collaboration more possible. Porten told us that it would be a big help if Apple could provide "an open JavaScript/WebCore CVS" to make it easier to track changes. At this point, there is no CVS provided. Apple does provide source tarballs, but nothing to make it easier to merge the code into KHTML or KJS. Porten also pointed us to Zack Rusin's blog and his response to Safari developer Dave Hyatt. Hyatt asked what Apple could do better, and Rusin had plenty of suggestions. Rusin noted that, at this point, Apple and KDE developers had gone in two different directions:
At some point the Open Source ideals which we apply to KHTML and commercial
setup in which you emerge yourself went in two different directions. At
this point we have two completely separate groups developing two different
versions of KHTML. We have absolutely no saying in the way you develop your
version of KHTML and you don't participate at all in the way we develop
KHTML.
Whatever solution we can come up will probably revolve around the following two: either we'll have some say in the way you develop WebCore's KHTML or you will start participating in the way we develop KDE's KHTML. It's basically doing whatever we can to somehow build a bridge between both teams. Rusin suggested sharing a bugs database, having Apple hire someone to merge patches between the KDE and Apple source trees in sync, having Apple more involved in KHTML head development, and several other suggestions. Rusin also suggested that the two teams organize a phone conference. While it's not clear if there's been a phone conference between the two groups, KDE developer Allan Sandfeld reports that there has been an IRC discussion and says that "Apple is being a nice guy for the time being, I will let them announce how things will improve once we have a solution," and asks for "no more 'vs.' stories for the time being." Porten has also said that collaboration between Apple and KDE is "still very well possible at this time."
It's just that the patch merging effort became non-trivial. Nothing that
couldn't be overcome by a more frequent patch exchange, though. The issue
of platform dependent API should be solved by appropriate
abstractions. This approach would help both parties as a cleaner design is
usually easier to maintain and more portable to newer versions of the
underlying system in the future.
Both parties are working hard on finding ways to cooperate more closely in the future. We have to respect each other's needs in terms of release cycles and policies but I'm sure we'll find a way. After all cooperation within KDE works as well although the project is made up of hundreds small but separate entities that all have their different background and motivation. We also asked Porten whether Apple, or any other company, had an ethical responsibility to go beyond the terms of the license and actually cooperate with development. Porten said he didn't want to get into a discussion of ethics, but said that it "often simply makes sense to get engaged further than what the license requires." At this point, it seems that the attention and negative publicity have helped to open the channels of communication between Apple and KDE once again. With any luck, the two groups will be able to find a way to collaborate on KHTML/WebCore in a way that makes sense for Apple and KDE.
Security Responding to the kernel ELF vulnerabilityPaul Starzetz has discovered a vulnerability in the Linux kernel that can be used to gain root access to the system. The vulnerability, published on May 11, affects the kernel's ELF (Executable and Linking Format) loader, which could allow a local user to use a manipulated binary to gain elevated privileges.
This vulnerability affects kernels in the 2.2, 2.4 and 2.6
series. According to Starzetz report, the flaw is in the function
It is possible to create a manipulated ELF binary, that specifies an ELF
program section to be loaded at the place of program arguments, but with no
access rights itself (that is, a page table level protection equal to
PROT_NONE). That will cause the strnlen_user() function to page fault at
the first attempt to count argument lengths. Moreover, the loading of
ELF sections happens just after the initial arguments have been set up in
the fresh memory space, so that it is easily possible to "override" the
predefined ELF memory layout. To illustrate this, here two memory
layouts:
(1) initial ELF memory layout before starting to load program sections: ----------------EMPTY------------------[ ARGS stack region ] TASK_SIZE (2) possible memory layout after loading ELF sections: ---------[CODE][DATA]------------------[FAKE][stack region ] TASK_SIZEwhere FAKE is an ELF section mmaped into memory with PROT_NONE rights specified. What seems odd is the amount of attention that the vulnerability is getting, or the lack thereof. While Colin Percival's report of a vulnerability in Hyper-Threading is getting attention, the ELF vulnerability has barely been a blip on the radar. To date, only Trustix has issued an alert and fix for this issue. Red Hat has just issued a kernel update, but the ELF vulnerability is not mentioned in the release announcement. We've checked the lists for Ubuntu, Debian, Mandriva, Slackware, Fedora, Fedora Legacy, Yellow Dog -- none of these distributions have issued a update yet for what appears to be a fairly serious local exploit. As of this writing, nearly a week has passed since Starzetz made the discovery public. At the same time, most of those vendors have released new versions of Squid to deal with a vulnerability that would allow malicious users to spoof DNS lookups. The Squid vulnerability was announced the same day as the ELF loader vulnerability. It does seem that a patch, at least for the 2.6 series, is available. Given the potential severity of the vulnerability, we're curious to see how long it will be before updates are made available from the major distributions. With Linux under close scrutiny for security vulnerabilities and vendor response times, one hopes that it will be soon.

Page editor: Jonathan Corbet Kernel development Brief items Kernel release statusThe current stable 2.6 kernel is 2.6.11.10, released on May 16 in response to yet another serious security hole.The current 2.6 prepatch remains 2.6.12-rc4. Linus has returned from his vacation and has merged about 150 patches into his git repository; these patches consist almost exclusively of security fixes, architecture updates, and various other important fixes. The current -mm tree is 2.6.12-rc4-mm2. Recent additions to -mm include the IPSec tree, some KProbes work, the fork connector patch (for process accounting), a DVB update, an ALSA update, a NUMA-aware slab allocator, and more fixes. Note that there is now a mailing list for people who would like to be notified when patches are added to -mm; see the 2.6.12-rc4-mm2 introduction for subscription information. The current 2.4 prepatch is 2.4.31-pre2, which was released by Marcelo on May 12. It contains a fix for the ELF core dump vulnerability and a small number of other patches.
Kernel development news Is hyperthreading dangerous?Hyperthreading (or symmetric multi-threading) is a hardware technique used to squeeze more performance out of modern processors. A hyperthreaded processor appears, in many ways, to be a set of two independent processors. These two processors share the same hardware, however, with only the processor registers and other state-dependent information being kept separate. Only one of the two CPUs can actually be executing at one time. Hyperthreading helps performance because processors often stall, waiting for memory accesses. When one processor in a hyperthreaded set must wait, the other can be executing. Hyperthreading thus enables greater utilization of the processor hardware; the resulting performance gains are said to be anywhere from 5% to 30%, depending on the workload.One of the resources shared by hyperthreaded processor sets is the memory cache. This sharing has its advantages: if processes running on the two processors are sharing memory, that memory need only be fetched into the cache once. That kind of sharing happens often; shared libraries are one obvious example. The shared cache also makes moving processes between hyperthreaded processors an inexpensive operation, so keeping loads balanced across the system is easier. The sharing of caches between hyperthreaded processors is also, however, the cause of a vulnerability identified in a heavily trailered report by Colin Percival. The core of the problem is that, by measuring the latency of specific memory accesses, a process can tell whether a given memory location was represented in the processor cache or not. A hostile process can load the cache with its own memory, wait a bit, then run tests to see which locations have been evicted from the cache. From that information, it can make inferences about which memory locations were accessed by the sibling processor in the hyperthreaded set. Two cooperating processes, running at different privilege levels, could make use of the cache to set up a covert channel for communication. In a highly secured system, these two processes might not be able to talk to each other at all normally. With a covert channel in place, information can be leaked from a privileged level to one less privileged, leading to all kinds of dreadful consequences - for somebody. Most systems, however, are not overly concerned about this sort of covert channel; there are easier ways to deliberately leak information. Mr. Percival, however, also shows how the vulnerability can be exploited to obtain information from processes which are not cooperating. In particular, he claims that it can be used to steal keys from cryptographic applications. A number of crypto algorithms have data-dependent memory access patterns; an attacker who can watch memory accesses can, for some algorithms, derive the key which was being used. The exploit discussed in the report attacks the OpenSSL key signing algorithm in this way. The paper makes a number of recommendations on steps which can be taken to mitigate this problem. The simplest is to simply disable hyperthreading; on Linux systems, it is a simple matter of configuring out hyperthreading support or booting with the noht option. Alternatively, the kernel could take care not to schedule potentially unfriendly processes on the same hyperthreaded set. Removing access to a high-resolution clock would make the necessary timing information unavailable, thus defeating such attacks. Cryptographic algorithms could be rewritten to avoid data-dependent memory access patterns. Processors could be redesigned to not share caches between hyperthreaded siblings, or to use a cache eviction algorithm which makes it harder to determine which cache lines have been removed. The Linux scheduler could certainly be changed to defeat attempted cache-based attacks on hyperthreaded processors, but the chances of that happening are small. There are numerous obstacles to any sort of real-world exploit of this vulnerability. The attacker must be able to run a CPU-intensive program on the target system - without being noticed - and ensure that it remains on the same hyperthreaded processor as the cryptographic process. The data channel is noisy at best, and it will be made much more so by any other processes running on the system. Timing the attack (knowing when the target process is performing cryptographic calculations, rather than doing something else) is tricky. Getting past all these roadblocks is likely to keep a would-be key thief busy for some time. In other words, there are almost certainly more effective ways of attacking cryptographic applications. Closing this particular hole is unlikely to be worth the trouble, extra complexity in the kernel, and performance impact it would require. So this vulnerability, despite all the press it has obtained, will probably not lead to any changes to the kernel in the near future. Anybody who is truly worried about this problem will be best off simply turning off hyperthreading for now. In the longer term, authors of cryptographic code may find that they need to add avoidance of data-dependent memory access patterns to their arsenal of techniques.
A new kernel timer APIJohn Stultz's new core time subsystem was covered on this page back in January. This patch set, which will be submitted soon for inclusion (into -mm), replaces a mess of architecture-specific time implementations with a cleaner, central time subsystem which can take full advantage of hardware time sources. Nishanth Aravamudan would now like to take advantage of the new low-level time code by replacing the kernel timer implementation. This work, if accepted, will lead to the incorporation of a new timer API to be used by kernel code when a function must be called at some point in the future.In current Linux kernels, internal time (for most purposes) is measured in "jiffies," which are really just a counter which is incremented when each timer interrupt happens. The new time code supersedes jiffies with an absolute, monotonically increasing count of nanoseconds. References to jiffies thus become a call to:
nsec_t do_monotonic_clock(void);
Using nanoseconds allows kernel code to work with high-resolution time in real-world units. That, in turn, lets kernel developers forget about the (error-prone) conversions between jiffies and real-world time which are currently necessary. Nishanth's add-on patch changes the timer subsystem to use nanoseconds as well. The current add_timer() and mod_timer() interfaces remain supported, but are deprecated. The new interface for setting (or modifying) a timer is:
int set_timer_nsecs(struct timer_list *timer, nsec_t expires);
void set_timer_on_nsecs(struct timer_list *timer, nsec_t expires,
int cpu);
This function will cause the given timer to be set to go off at expires, which is an absolute nanoseconds count. Usually, expires will be calculated by adding the desired delay (in nanoseconds) to whatever do_monotonic_clock() returns. It's worth noting that this patch changes the meaning of the expires field in the timer_list structure. This field is now represented in an internal "timer intervals" unit, rather than in jiffies. If the old add_timer() and mod_timer() interfaces are used, the expires field will be silently converted to the internal format. Code which performs calculations on expires (by increasing the delay and calling mod_timer(), for example) could be in for a surprise. This patch also deprecates schedule_timeout(), in favor of these functions:
nsec_t schedule_timeout_nsecs(nsec_t timeout);
unsigned long schedule_timeout_usecs(unsigned long usecs);
unsigned int schedule_timeout_msecs(unsigned int msecs);
All three of these functions will set a timer for the given delay (which is a relative value, not absolute), then call schedule().
Clusters and distributed lock managementThe creation of tightly-connected clusters requires a great deal of supporting infrastructure. One of the necessary pieces is a lock manager - a system which can arbitrate access to resources which are shared across the cluster. The lock manager provides functions similar to those found in the locking calls on a single-user system - it can give a process read-only or write access to parts of files. The lock management task is complicated by the cluster environment, though; a lock manager must operate correctly regardless of network latencies, cope with the addition and removal of nodes, recover from the failure of nodes which hold locks, etc. It is a non-trivial problem, and Linux does not currently have a working, distributed lock manager in the mainline kernel.David Teigland (of Red Hat) recently posted a set of distributed lock manager patches (called "dlm"), with a request for inclusion into the mainline. This code, which was originally developed at Sistina, is said to be influenced primarily by the venerable VMS lock manager. An initial look at the code confirms this statement: callbacks are called "ASTs" (asynchronous system traps, in VMS-speak), and the core locking call is an eleven-parameter monster:
int dlm_lock(dlm_lockspace_t *lockspace,
int mode,
struct dlm_lksb *lksb,
uint32_t flags,
void *name,
unsigned int namelen,
uint32_t parent_lkid,
void (*lockast) (void *astarg),
void *astarg,
void (*bast) (void *astarg, int mode),
struct dlm_range *range);
Most of the discussion has not been concerned with the technical issues, however. There are some disagreements over issues like how nodes should be identified, but most of the developers who are interested in this area seem to think that this implementation is at least a reasonable starting point. The harder issue is figuring out just how a general infrastructure for cluster support can be created for the Linux kernel. At least two other projects have their own distributed lock managers and are likely to want to be a part of this discussion; an Oracle developer recently described the posting of dlm as "a preemptive strike." Lock management is a function needed by most tightly-coupled clustering and clustered filesystem projects; wouldn't it be nice if they could all use the same implementation? The fact is that the clustering community still needs to work these issues out; Andrew Morton doesn't want to have to make these decisions for them:
Not only do I not know whether this stuff should be merged: I don't
even know how to find that out. Unless I'm prepared to become a
full-on cluster/dlm person, which isn't looking likely.
The usual fallback is to identify all the stakeholders and get them to say "yes Andrew, this code is cool and we can use it", but I don't think the clustering teams have sufficent act-togetherness to be able to do that. Clustering will be discussed at the kernel summit in July. A month prior to that, there will also be a clustering workshop held in Germany. In the hopes that these two events will help bring some clarity to this issue, Andrew has said that he will hold off on any decisions for now.

Page editor: Jonathan Corbet Distributions News and Editorials FreeBSD 5.4 on AMD64Regular readers of this column will recall our series of mini-reviews of several Linux distributions on the AMD64 platform and their readiness to function as developer workstations. Originally, this series also meant to include FreeBSD, as the most popular of the BSD operating systems, but we were somewhat discouraged by this report at NewsForge, which claimed that FreeBSD 5.3 shipped without support for 32-bit FreeBSD binary compatibility and without support for 64-bit Linux binary compatibility. This fact would almost certainly have made FreeBSD 5.3 look incomplete in comparison with most current Linux distributions, so we decided to wait for version 5.4 before attempting to install FreeBSD on our AMD64 box.Six months after FreeBSD 5.3, the second production version of FreeBSD 5.x series was released. Has it addressed the concerns in the above-mentioned review? To find out, we installed the AMD64 edition of FreeBSD 5.4 on a system with the following specifications: AMD64 3500+ processor (2.2GHz), K8N Neo2 (Socket939) mainboard from Micro-Star International, 2 GB of DDR SDRAM, 2 x 120 GB Maxtor hard disks, Plextor PX-712A DVD/CD Rewritable Drive, and NVIDIA GeForce4 Ti 4600 graphics card. First, we installed a base FreeBSD system, rebooted, then proceeded with further package installation from a local FTP mirror. To save time, we did not compile desktop applications from source, but used FreeBSD's binary packages instead; with 'pkg_add -r kde' and 'pkg_add -r gnome2', we had both the KDE and GNOME desktops set up in no time. We also added Firefox, Apache, PHP and a few other popular applications. We started investigating the compatibility issues right after setting up our desktop environment. We checked out the default kernel configuration file, which included options for "COMPAT_IA32" and "COMPAT_LINUX32". This looked promising, but we were still curious about how complete the AMD64 port was. Looking through the FreeBSD 5.4 package trees we noted that there were a total of 10,383 packages for the i386 architecture, and 9,807 packages for the AMD64 architecture, which suggested that almost 95% of all FreeBSD packages have been ported to the AMD64 platform. This is in line with most Linux distributions. Running 'diff' on the two package sets gave us a more clear picture about what is missing from the 64-bit edition; besides the usual culprits, such as OpenOffice.org, Opera, proprietary multimedia codecs, and Java-based applications (Eclipse, Jakarta...), we also noted the absence of Azureus, Blender, TightVNC and Wine, among other packages. The 'sysinstall' interface did list a few dozens of Linux applications that could be installed under a binary compatibility mode, but it did not include anything terribly exciting. This was disappointing. At this point we couldn't help thinking about how far Linux has evolved in providing a near-complete support for 64-bit processors. Fedora, Mandriva, SUSE and Ubuntu come pre-configured with 32-bit compatibility libraries, so that applications that do not compile under AMD64 (e.g. OpenOffice.org) can be run in a 32-bit mode. Debian provides an excellent write-up about how to set up a minimal 32-bit Debian system in a chroot-ed environment and how to integrate transparently any 32-bit applications into the main 64-bit system. Even though none of these solutions are ideal, they are certainly workable - at least until OpenOffice.org compiles under AMD64 and until makers of proprietary software, such as Opera, RealPlayer, Acrobat Reader, Flash Player, and others wake up and start building 64-bit binaries. Unfortunately, this means that the 64-bit edition of FreeBSD remains somewhat limited as a workstation. A brief search on the Internet revealed that, while it was not impossible to install the 32-bit Linux binary edition of OpenOffice.org on a 64-bit FreeBSD system, this was by no means straightforward and certainly not officially supported. Of course, if you don't need any of the proprietary applications or OpenOffice.org, then FreeBSD 5.4 is certainly a workable system. We only spent one day testing it, but had no trouble with installing a large number of applications from the binary package pool. Some hardware, such as sound cards, still required manual setup with 'kldload', but the network card and USB mouse were detected and set up automatically. FreeBSD 5.4 comes with the very latest open source applications available today; these include X.Org 6.8.2, GNOME 2.10, KDE 3.4, Apache 2.0.54, and PHP 5.0.4, just to name a few. As a server, FreeBSD 5.4 seems to be a noticeable improvement over 5.3; as an example, we host DistroWatch.com on FreeBSD and had a few serious problems with version 5.3 (which our hosting provider confirmed to have affected a number of other FreeBSD 5.3 boxes), but these problems have yet to manifest themselves after upgrading to FreeBSD 5.4. While talking about FreeBSD as a desktop solution, perhaps it is a good time to mention a new project called PC-BSD. PC-BSD is the first attempt (besides Mac OS) to create a truly user-friendly BSD-based operating system, complete with a graphical installer and automatic hardware configuration. Dru Lavigne, a well-known BSD advocate and author of several BSD books, concluded in her recent review of PC-BSD that "this is one CD I'll definitely be passing out and I look forward to watching this project mature and achieve its goals." Although still in early beta, there is little doubt that, in terms of user-friendliness, PC-BSD has come close to matching some of the top Linux distributions on the market. The installation is a breeze and the first reboot takes users straight into a pre-configured KDE desktop. The upcoming release will even include a graphical FreeBSD package manager! So how did the AMD64 edition of FreeBSD 5.4 fare in our brief test? As a server, it is an excellent operating system. As a workstation, we won't use it and won't recommend it. It lags behind both the i386 edition of FreeBSD, and the AMD64 editions of all major Linux distributions, mainly due to the limited support for 32-bit applications. Without it, the overall experience of running the 64-bit edition of FreeBSD on the desktop is simply not on par with any of the current 64-bit Linux distributions.

Ubuntu "Breezy Badger" Colony CD 1The first pre-release of Ubuntu 5.10 for testing. So far there's only the install CD, no live CD yet. "There aren't many visible installer changes beyond Hoary yet, as we've been concentrating on merging work from Debian unstable, on getting things up and running at all, and on design work for this development cycle. To date, there have been 4741 uploads to Breezy, of which most (4092) have been automatic syncs from Debian unstable. Many of the remainder have been improvements to the rest of the distribution, including a good deal of work on the compiler toolchain."
Distribution News Debian release updateDebian release manager Steve Langasek has sent out an update on progress toward a sarge release. Despite some departures from the previous schedule, the project is still aiming for an end-of-month release. "Right now, this schedule is looking more ambitious than when we cooked it up, but it's not completely out of the question -- we just need to pick up the pace a bit."

Distribution reviews SUSE 9.3: More, Better, Faster, Now! (Linux Planet)Linux Planet reviews SUSE Linux 9.3. "Novell's latest release of SUSE Linux, SUSE 9.3, demonstrates Novell's continuing commitment to delivering polished, off-the-shelf Linux distributions for the desktop and professional markets. October 2004, which is when the previous version of SUSE Linux was released, seems like only yesterday. So what's new--and, perhaps, why should people care?"
Getting to know Puppy Linux (Desktop Linux)Desktop Linux reviews Puppy Linux. "For a distribution that provides the typical tools that a user might need to do their work, Puppy Linux is the superior small Linux distribution. Puppy Linux has two other very strong points that make it the small Linux distribution of choice. The first is the ease with which Puppy Linux can generate a bootable USB thumb drive version of itself."
My Desktop OS: VectorLinux (NewsForge)Here's an article on NewsForge from a Vectorlinux fan. "I became acquainted with VectorLinux a year ago when I was testing several distros for an old Pentium II I had. It was running Slackware fine, but I was searching for something more complete. VectorLinux not only proved faster than the original Slackware but was also packed with a lot of goodies that Slackware lacks: Flash support, Java, Firefox extensions, and many more."
Page editor: Rebecca Sobol Development Fish - The friendly interactive shellA User-Friendly Shell
IntroductionA great deal of effort has been spent in the last decade trying to make computers more user friendly. While much progress has been made on making graphical user interfaces more user friendly, much less has happened with non-graphical programs such as shells. This is unfortunate, since there are still many things that are inherently easier to do using a shell. The concept of commands, pipelines and environment variables are somewhat complex, but I believe modern shells are harder to use than they have to be, both for the beginner and for the seasoned shell hacker. I have written a new shell called fish, or the friendly interactive shell, that tries to solve several issues that I have found with other shells.fish features syntax highlighting, advanced tab completion features, discoverable help, a revised shell syntax and many other features. In this article, I will describe some of the features found in fish, and explain why I think they are useful. (Click here for the full article.)

Page editor: Forrest Cook Linux in the news Recommended Reading Open-source divorce for Apple's Safari? (ZDNet)ZDNet covers the disconnect between Apple and the KHTML developers. "The suggestion, which KHTML developers said they were unlikely to accept, comes as Apple tries to quell rising dissatisfaction among the original architects of KHTML. Two years after hailing Apple as a white knight, those developers are calling the relationship between their group and the computer maker a 'bitter failure.' In a conflict some call emblematic of what can go wrong when corporations embrace open-source projects, developers are airing longstanding gripes against Apple, accusing the computer maker of taking more than it gives back to the open-source group."
A Prior Art How To (Groklaw)Groklaw covers the Patent Law How To on finding prior art. " Patent law is a legal speciality, and it's not my speciality, so I've been asking lawyers in the field to help us. The help is now here, and there will be more coming. The important point is this: searching for prior art isn't quite as simple as you might think. PubPat's Executive Director Dan Ravicher explains the difference: "To be worthwhile, the prior art has to be exactly the same or any differences between it and the targeted patent have to fall within the judicially narrowed concept of obviousness that exists in patent law today, which is much, much less than what most reasonable technologists would consider obvious.""
Companies Dell founder dons Red Hat (Vnunet)Vnunet looks into a 2004 investment by Michael Dell in Red Hat. "Billionaire Michael Dell, founder of the world's largest computer manufacturer, and a stalwart of the Windows/Intel alliance, has made a $99.5m investment in Linux vendor Red Hat. The investment was made in January 2004 through Michael Dell's investment company MSD Capital, according to an SEC filing."
Legal EU plans for software patents hit fresh obstacle (FT)The Financial Times catches up with the European patent directive as it goes back to the Parliament for consideration. "The latest attempt to introduce a more restrictive regime comes from Michel Rocard, a Socialist member of the European parliament. The former French prime minister has been charged with steering the law through parliament. According to his draft amendments, which have been seen by the Financial Times, patents should not be granted for 'the treatment, the manipulation, the representation and the presentation of information through software'." (Thanks to Philip Webb).
A Modest Proposal (law.com)Here's a Law.com article discussing a patent reform proposal which is expected to be submitted to the U.S. Congress in the near future. This reform does not come close to solving the patent problem, but it could make life harder for litigation companies. "The most contentious proposal -- intended to undercut the power of patent-holding companies -- would limit the ability of a patentee to get an injunction against an alleged infringer. Courts would have to consider whether the patentee is likely to suffer irreparable harm in deciding whether to grant an injunction. Specifically, courts would look at whether the patent holder is commercializing his or her invention."
Who Will Own Ideas? (Technology Review)The June issue of the Technology Review is concerned with intellectual property issues. Among others, there is an article by Lawrence Lessig inspired by what he has seen in Brazil. "So the U.S. calls them pirates, and they reform their ways--not by more faithfully buying our products, but by finding ways to remain creative without infringing our rights. This is free software 'ported'--as software engineers say--to free culture, and it inspires all the hype typical of such movements. 'We're hoping,' the leader of the free-software lab explained, 'everybody is going to start producing their own media content and then they won't have to watch TV anymore.'"There is also a Linux v. Microsoft story in this issue: "This because for all its flaws, the open-source model has powerful advantages. The deepest and also most interesting of these advantages is that, to put it grossly, open source takes the bullshit out of software."
Interviews Sun's Gosling: Already Plenty of Java 'Harmony' Under the Sun (DevX)DevX talks with James Gosling about the Harmony project and other Java topics. "The 'clear need' that [Geir] Magnusson cites is anything but clear to Gosling, who says Sun has received negative response from the enterprise development community regarding the idea of open-source Java. 'We've got several thousand man-years of engineering in Java, and we hear very strongly that if this thing turned into an open source project--where just any old person could check in stuff--they'd all freak. They'd all go screaming into the hills.'"
MusE: MIDI Sequencing for Linux (O'ReillyNet)O'ReillyNet talks with the developers of MusE, a MIDI and audio sequencer intended to be a complete multi-track virtual studio. "Frank Neumann, a 36-year-old computer scientist from Karlsruhe, Germany, and one of the developers of MusE, sums up the current state of music production applications for Linux: "It's always a nice warm feeling when you show an application like MusE to people and they just go, 'Whoa--I didn't know Linux audio stuff was already this far!'""
Wind River's Linux transformation (ZDNet)ZDNet interviews Ken Klein, CEO of Wind River Systems. "Q: What has Wind River been, and what is it becoming? Klein:We were closed and narrow in terms of our partnerships. We were taking a very adversarial approach toward Linux. We've turned 180 degrees. We're viewing Linux as incremental to our business. In set-top boxes, Linux is a great fit."

Resources The Daemon, the GNU and the Penguin, Ch. 8 (Groklaw)Groklaw has published chapter 8 of the online book "The Daemon, the GNU and the Penguin" by Peter Salus. This chapter looks at Richard Stallman's early history. "I have quoted Richard at length, because I think that his "voice" should be heard. He has frequently said that "Software wants to be free." But in 1982 and 1983 his was a single, lonely voice."
The Daemon, the GNU and the Penguin, by Dr. Peter H. Salus - Errata (Groklaw)Peter H. Salus provides some errata on the Groklaw series The Daemon, the GNU and the Penguin. "One of the "problems" of writing is that your readership can be quite notable. I have received clarifying comments from two of the major "participants.""
Linux in Government: Optimizing Desktop Performance, Part I (Linux Journal)Tom Adelstein offers tips and tweaks for Linux desktop optimization. "In this article, we look at the Linux desktop in a slightly different light. We think of it as a computer system that maximizes its strength as a consumer product. When we optimize Linux for the consumer, it becomes a fast interface. If you have complained about the speed of OpenOffice.org or Firefox or about the amount of time Linux takes to boot up, this set of optimizations should change your perception. Linux can boot up quickly, the word processor can spring open and the browser can fly. So, let's make these adjustments so your computer can fly."
Researchers speed, optimize code with new open source tools (NewsForge)NewsForge covers automatic code generation with SPIRAL. "[Blue Gene Systems Architect Jose] Moreira said SPIRAL does, in fact, represent a new generation of self-optimizing scientific libraries, also emphasizing the importance that it be open source. "The fact that SPIRAL uses an automated approach to code optimization results in scientific libraries that can be highly optimized to each specific architecture, including Blue Gene/L," he said. "It is very important to us that all potential IBM customers can have access to SPIRAL and the generated scientific libraries.""
Reviews At the Sounding Edge: Introducing seq24 (Linux Journal)Dave Phillips reviews seq24 on Linux Journal. "In this month's column, we look at the seq24 MIDI sequencer to see how you can use it in a Linux-based MIDI music production system. Given working ALSA and JACK installations, this system is easy to set up and use, great fun and a valuable production tool."
Miscellaneous Linux Community Implodes (PC Magazine)We'll get grief for this but...here's the latest bizarre Dvorak piece in PC Magazine. "I can tell you this much: Normal people do not like being associated with fanatics and lunatics. Once Linux gets the image as the OS for the criminally insane, it's a dead duck. Unless the community gets a handle on this, grows up, and rebukes the extremists, the trash heap of history is where this is all headed." The weirdest part is that he is talking about the response to Maureen O'Gara.
