LWN.net Weekly Edition for September 28, 2006
Much ado over licenses
Selling a new license to the kernel developers was always going to be an uphill battle. They are a large and strong-minded crowd, occasionally suspicious of the Free Software Foundation and its attitude toward Linux, and happy with the licensing that they have now. Given the immense practical difficulties involved in changing licenses, there would have to be a strong incentive to get the developers to even try.The odds of a license change fell even further earlier this year, when Linus Torvalds made his opposition to the anti-DRM provisions of the GPLv3 draft known. For some time, it appeared that Linus was alone in that position, however; few other developers had made public statements on the license. Even Linus wondered about it:
So while I personally thought it was pretty clear that the GPLv2 was the better license for the kernel, I didn't want to just depend on my own personal opinion, but I wanted to feel that I had actually made my best to ask people.
So he put together a quick discussion list involving the top 30 or so kernel developers (see the message quoted above for the the exact selection criteria) and held an informal poll. The results were as clear as it gets: none of the developers polled was positive about the license, and most were strongly negative. Among this crowd of most active kernel developers, nobody is prepared to say that moving to GPLv3 would be a good thing for the kernel project to do.
A subset of these developers put their names onto a separate position statement. Some of the positions taken in that statement are quite strong (see Rusty Russell's take), to the point that not all were willing to support it. It also appears that, while the anti-DRM provisions are almost unanimously opposed, a number of developers are sympathetic to the patent-related terms in GPLv3.
The anti-DRM clauses are, indeed, at the heart of the problem. The GPLv3 draft requires that, if somebody ships you a device which runs GPLv3-licensed code, they must also provide you with everything required to rebuild and reinstall that code - including encryption keys if the hardware requires them. Those who support this language see it as a fundamental guarantee of the freedom that comes with free software - the freedom to replace that software if need be. In particular, these people want to be able to replace software which implements unpleasant DRM schemes or other user-hostile behavior.
In the discussions that have followed, it is hard to find kernel developers who support locking up content and abridging fair-use rights with DRM schemes - though some do see situations where locking down a system's software makes sense. But they see the language in the GPLv3 draft as restricting the possible uses of their software, and they don't like it. The cure seems worse than the disease.
The core question behind this whole debate, perhaps, is this: what, exactly, do we want to accomplish with our licenses? Just as there is disagreement over what kinds of problems can be solved by passing laws, there is no consensus on which problems can be addressed with license terms. One can argue that oppressive DRM is a societal or legal problem, and that it should be addressed at those levels through a reaffirmation of what fair-use rights should really be rather than by adopting a license which tries to keep specific software from being used to implement DRM. A license can be a hefty hammer, but not every problem is a nail.
Regardless of the reasoning, the fact is that the GPLv3 draft is currently in a difficult spot. There appears to be no way it will be adopted for the kernel in its current form; there has also been quite a bit of speculation that a number of other important projects will either resist the new license or, possibly, fork into GPLv2 and GPLv3 versions. GPL-licensed libraries are of particular concern. The prospect of having to carry around two versions of the C library - one for each version of the GPL - is not particularly appealing. This is the scenario that some of the kernel developers warn about in their position statement; anybody who dismisses it should have a good reason for believing that it will not come about.
There are a lot of good things in the GPLv3 draft. The updating of the language for worldwide applicability is something we will almost certainly want, sooner or later. The software patent provisions have the potential to deter patent attacks against free software users - an important protection in the absence of a real fix for the patent problem. The "this code is not a technical protection measure" clause may offer similar protection from some attacks based on DMCA-like laws. All of this, and more, is worth having - but only if the new license can find acceptance from those who have so wholeheartedly adopted GPLv2. The Free Software Foundation is going to have to make a difficult decision over the next few months: it can keep the controversial terms and risk the consequences, or increase the chances of a successful GPLv3 by dropping terms that, in its opinion, are of fundamental importance.
[Other things to see: the FSF's response to the position statement and Linus Torvalds's Ode to GPLv2. There is also the announcement of the first discussion draft of the GNU Free Documentation License, version 2, which almost appears to have gotten lost in the noise.]
The return of Iceweasel
Back in January, 2005, LWN ran an article about Debian and Mozilla's trademarks. In particular, the Mozilla trademark policy places strict requirements on where names like "Firefox" can be used, some of these requirements do not mix well with the Debian Free Software Guidelines. Recent events now warrant a new look at the issue.Any distribution of Mozilla software which diverges from the official tarballs must use a different name unless specific approval has been obtained from Mozilla. Debian's version does indeed differ in a number of ways. The project could seek approval from Mozilla to call its version of the browser "Firefox," but that approval does not help others who may wish to redistribute the software after receiving it from Debian. Also, the Debian Firefox build omits the official logos, since they carry a non-free license; that is another change which runs afoul of the trademark rules.
In the 2005 discussion, the Debian Project had seemingly come to a resolution with the Mozilla Foundation, as represented by Gervase Markham, where Debian would be trusted to make reasonable changes and the omission of the logos was condoned. All seemed well, and Debian has been shipping Firefox under this understanding for over a year. In February of this year, however, Mike Connor from Mozilla Corporation posted a bug report with the Debian project. This bug, marked "serious," stated that shipping a browser called "Firefox" was a trademark violation:
Under the previous understanding, the Mozilla Foundation had seemingly concluded that it could trust Debian to be judicious in its patches to Firefox. The Mozilla Corporation, instead, is taking a harder line:
The conversation then lapsed until September 18, when Mr. Connor restarted it. His position has not softened:
Anybody familiar with the Debian Project will know that asking it to "bend the DFSG a little" tends not to go over very well.
Mozilla's immediate complaint is about the omission of the official logo, a change which had seemingly been approved back in 2005. But Mr. Connor is also taking issue with a number of the other patches shipped by Debian, and has repeatedly said that every patch that the distribution applies must be approved by the Mozilla Corporation ahead of time.
So what happened to the previous understanding? It appears that the shift to the Mozilla Corporation has brought a new approach to trademark policies - and new people into the trademark enforcement role. Meanwhile, the understanding that the Debian Project thought it had was never really codified onto a piece of paper with the requisite signatures - and, as a result, it is easy for the Mozilla Corporation to change. A cardinal rule for dealing with corporations is to always assume that the people you are dealing with will soon be replaced by others with a much more hostile attitude; that would appear to be what has happened here. With regard to the logo:
The Debian developers have no intention of going against Mozilla's wishes. Eric Dorland, one of the Debian Firefox maintainers, did ask for some time, however:
The response was not particularly sympathetic:
Eric also asked for clarification on the patch review policy, wondering if it applied even to security updates. The answer was clear:
As for your straw man about security bugs, what security bugs would you be fixing with your own patches? If there are security bugs, they should be fixed upstream, not in your own tree.
Many people do not consider security to be a "straw man," however. Debian stable currently includes Firefox 1.0.4, which is no longer supported by the Mozilla developers. So Debian must backport its own security fixes, and may not want to wait for the Mozilla bureaucracy to review those fixes before putting them out. The Mozilla response here is that users should simply be force-upgraded to a supported version; that is, indeed, what a number of distributors do, but people are not always happy about it. There are not many other projects which force upgrades in this manner.
The end result of all this, as expressed by Steve Langasek:
Eric Dorland has stated that he will be changing the name of the browser soon. Previously, this scenario has been described as the "Iceweasel" approach - but Eric has not said what name he will be using. He has asked if Debian sarge can continue to ship "firefox," or whether the name will have to be changed in the stable distribution; that question has not yet been answered.
Debian is not the only project to express some frustration with Mozilla; consider this message sent to the Fedora advisory board in August on why Firefox security updates tend to be slow in coming:
See also this message from last June on problems the Ubuntu developers have had in keeping Firefox secure in their distribution.
The Mozilla project has, mainly via the Firefox browser, changed the way people work with the web. It has brought millions of people into the community of free software users and ended the destructive domination of a single, proprietary browser. Firefox is good stuff, and we are far richer for its existence.
One cannot help wondering, however, if the Mozilla Corporation, now one year old, isn't losing touch with the free software community it is ostensibly part of. Releasing software under a free license means losing control over what happens to it, but Mozilla appears to be having a hard time letting go. The result makes life harder for Linux distributors, and for Linux users as well.
Nobody really wants to fork Firefox. The Mozilla Corporation, however, would appear to be requiring distributors to do exactly that, whether they want to or not. No distributor has any interest in shipping Iceweasel, but it appears that a number of us will be using it anyway - or, perhaps, looking harder at some of the other free browsers out there.
Highlights from Linux Kongress
The 13th annual International Linux System Technology Conference, also known as Linux Kongress, took place September 5 - 8 in Nürnberg, Germany. As a technical Linux event Linux Kongress is smaller in scale than the Ottawa Linux Symposium and linux.conf.au. Still the conference sessions and tutorials included a number of quality talks from familiar members of the Linux and open source communities such as Heinz Mauelshagen, Lars Mueller, Theodore Ts'o, Volker Lendecke, Alan Robertson, and Daniel Phillips.
A few of the talks stood out. One such talk was Felix von Leitner's presentation titled "Benchmarking, round 2: I/O Performance", in which he tested file system performance on Linux, Windows, OpenSolaris, NetBSD, FreeBSD, and OpenBSD in order to better understand the scalability of different operating systems and IP stack throughput. Based on von Leitner's benchmarking methodology Linux has the fastest file system - reiser4.
The testing theme continued with Poornima Bangalore, whose presentation was on the topic of "Best Practices in Linux Kernel Testing." Her talk detailed many of the key differences between traditional and open source testing. She pointed out that mainline kernel testing is more challenging than testing many other open source projects because of the rapid development and the different sub trees in the kernel: the stable kernels are released every 6 weeks or so, release candidate (-rc) kernels are available every week, and experimental (-mm) kernels are available every few days. Poornima shared best practices regarding kernel configuration, hardware configuration, test automation, test coverage, and first failure data capture.
Heinz Mauelshagen gave a talk on device-mapper architecture features and the related target feature set. In the talk "Linux as a Hypervisor," Jeff Dike discussed the evolution of the hypervisor support in the Linux kernel and how capabilities such as ptrace, AIO and O_DIRECT make a difference to virtual machines. He also talked about the implications of FUSE (filesystems in userspace) and the manageability benefits of exporting a UML filesystem to the host. Lars Marowsky-Bree's presentation on Heartbeat 2 and Xen explored Heartbeat's ability to manage Xen guests. He expanded on Heartbeat's architecture and its integration with Xen to enable resource reallocation, globally ordered recovery actions, and data center automation policies using the Cluster Resource Manager (CRM).
Mattias Rechenburg's presentation on "Using Enterprise Data Centers with OpenQRM" showcased the state of OpenQRM an open source project to achieve high-availability, scalability, and deployment, service and server virtualization on a variety of operation system. In spite of OpenQRM's pluggable architecture, the audience focused on the fact that it depends on a binary module which requires support from Qlusters. The general sentiment from the audience was they were not interested if they couldn't get support from Red Hat, IBM, Hewlett-Packard etc.
In "Real-Time Approaches to Linux," Ted Ts'o shared his perspective on enterprise real-time computing and how it differs from so-called traditional real-time computing. He emphasized the changing requirements in enterprise software and how high throughput is not enough because customers increasingly also require latency guarantees, especially in particular military applications and trading systems. It was interesting to hear about the benefits and tradeoffs of different approaches to enterprise real-time including RTAI and Ingo Molnar's CONFIG_PREEMPT_RT.
Ted suggested that guidelines outlined by his colleague Paul McKenney can be used to evaluate the different approaches to enterprise real-time. This includes quality of service, the amount of code inspection required when a new feature is added, the API provided to applications, the relative complexity, fault isolation, and supported hardware and software configurations.
Although IBM presently has only one customer that plans to deploy enterprise real-time computing, the ability to support large SMP systems, TCP/IP, commercially available middleware, and databases makes it an area to watch in the future. Ted also elaborated on the features of IBM's real-time JVM/SDK (aka IBM Websphere Real-Time v1.0) such as RTSJ (Real-time specification for Java), the Metronome real-time garbage collector, and AOT (Ahead of Time Compilation). The talk emphasized that there are many new applications for real-time operating systems, and in particular enterprise real-time Linux.
Maddog provided the final keynote on having fun with open source in his own inimitable way.
Security
Searching for Insecurity
Google and other search engines provide an invaluable service for people looking for web-based information, but, as several automatic teller machine (ATM) vendors found out recently, search engines can also be useful for people looking for information that might better stay hidden. Google searches have recently turned up operator manuals for several ATM models which include information on how to enter maintenance mode, along with default administrative passwords. This information was promptly put to use in ways not intended by the manufacturers. ATM manufacturers are not the only folks who should be concerned about this, search engines store a wealth of sensitive information and for those with malicious intent, they are a gold mine.
Two weeks ago, a news report about someone reprogramming an ATM led a security researcher to see what information was available about the ATM model shown in a CNN report. It turns out that it was not difficult to come up with information that could be used to make the ATM believe that it was handing out $5 bills when it was really providing $20 bills. Neither the researcher (nor, presumably, the unknown ATM reprogrammer) confirmed that it was a web search that led to the information, but a subsequent report makes it clear that the manual was available via a simple Google query.
Other ATM vendors' products were then targeted with the same results. The major security issue in these cases appears to be the well known 'default password' vulnerability. The default administrative passwords were listed in the operator's manual, which is not unreasonable, but, like default passwords everywhere, they were not routinely changed as part of the installation.
This kind of vulnerability is not at all specific to ATM machines; various kinds of hardware (routers, servers, PBX systems, etc.) have been or are susceptible. Of course, it is not just hardware that suffers from well known or easily discovered default passwords, many software packages have exactly the same problem. Finding vulnerable installations of those packages has been made a great deal easier with search engines, particularly Google with its rich set of searching operators.
Many software packages, especially web-based packages, show that they have been installed correctly by displaying a default page. The Apache web server on many Linux distributions installs a page that indicates its presence (and its version, which may come in handy the next time an Apache vulnerability is discovered) and the fact that it has not been completely configured. Searching for these default pages, especially for packages (like portals, blogs, picture galleries, etc.) that have a default administrative password, will generate a list of sites that may not have done anything more than install the package. This is a pretty good place to start trying default passwords.
Web searching can also generate lists of sites that are vulnerable to known exploits simply by looking for sites displaying 'VulnerableApp v0.0.1'. In many cases, the applications were installed at one point and then orphaned but not removed and the administrator has completely forgotten about their presence. It can be difficult to keep up with security updates for an application that one has forgotten is even installed.
This just scratches the surface of the kinds of information, useful to those with malicious intent, that can be found via search engines. Johnny Long has done various conference presentations and written a book, Google Hacking for Penetration Testers describing these techniques. His homepage has a great deal of information on using Google to find interesting things on the web.
Using these techniques against your own site is one of the best ways to determine how vulnerable you are. Finding web applications that were forgotten or were never completely configured is just one step in the right direction. These techniques could also find directories that provide indexes or publicly exposed documents that were believed to be secure. It is almost always an eye opening experience to find out how much information the search engines have about one's site.

Kernel development
Brief items
Kernel release status
The current stable kernel remains 2.6.18. The 2.6.19 merge window has opened and, as of this writing, just over 2000 patches have landed in the mainline git repository - see the separate article, below, for a summary.The current -mm tree is 2.6.18-mm1. Recent changes to -mm include an xpad dance pad driver, a new version of the SLIM security module, and a number of fixes. The -mm tree is shrinking quickly as patches move into the mainline.
Adrian Bunk has released the first 2.6.16.30 prepatch. Along with the usual fixes, this prepatch adds a few new drivers, which has caused some observers to wonder about criteria for patches in the long-term 2.6.16 tree. It appears that 2.6.16, going into the future, will be a bit more open to new code than the regular -stable tree.

The 2.6.19 process begins
The 2.6.19 merge window has opened, and the flood of patches into the mainline has begun. As of this writing, it has only begun - the 2000 or so patches which have been merged after 2.6.18 are likely to be outnumbered by those that remain. Here's what has found its way in so far, starting with the user-visible changes:
- The OCFS2 filesystem is no longer marked "experimental."
- A number of InfiniBand updates, including better RDMA support and
drivers for some new adapters.
- Support for IPv6 policy routing rules - and a mechanism for the
creation of multiple IPv6 routing tables to support those rules.
- The parallel ATA driver
patch set.
- The labeled networking
patch set implementing the Commercial
IP Security Option.
- Support for the Atmel AVR32 architecture.
- Super-H support for Titan, SH7710VoIPGW and I-O DATA Landisk boards.
- Big updates to the PowerPC and S/390 architectures. Among other
things, S/390 has gained KProbes support.
- New drivers for external flash on ATSTK1000 boards, TI OMAP1/2 i2c busses, ESI Miditerminal 4140 devices, Areca RAID controllers, SuperTrak EX8350/8300/16350/16300 SCSI controllers, QLogic QLA3xxx network interfaces, IBM eHEA Ethernet adapters, and the Ethernet controller found on Cirrus Logic ep93xx boards. The controversial aic94xx driver, originally written by Luben Tuikov and since revised by a number of others, has also been merged.
Changes visible to kernel developers include:
- The CHECKSUM_HW value has long been used in the networking
subsystem to support hardware checksumming. That value has been
replaced with CHECKSUM_PARTIAL (intended for outgoing packets
where the job must be completed by the hardware) and
CHECKSUM_COMPLETE (for incoming packets which have been
completely checksummed by the hardware).
- A number of memory management changes, including tracking of dirty
pages in shared memory mappings, making the DMA32 and HIGHMEM zones
optional, and an architecture-independent mechanism for tracking
memory ranges (and the holes between them).
- The pud_page() and pgd_page() macros now return a
struct page pointer, rather than a kernel virtual address.
Code needing the latter should use pud_page_vaddr() or
pgd_page_vaddr() instead.
- A number of driver core
changes including parallel device probing and some improvements to
the suspend/resume process.
- There is now a notifier chain for out-of-memory situations; the idea
here is to set up functions which might be able to free some memory
when things get very tight.
- The semantics of the kmap() API have been changed a bit: on
architectures with complicated memory coherence issues,
kmap() and kunmap() are expected to manage coherency
for the mapped pages, thus eliminating the need to explicitly flush
pages from cache.
- PCI Express Advanced Error Reporting is now supported in the PCI
layer.
- A number of changes have been made to the inode structure in
an effort to make it smaller.
- The no_pfn() address space operation has been added.
For anybody who is curious about what else is likely to be merged, Andrew Morton's 2.6.19 -mm merge plans document is worth a look. Highlights include another set of memory patches (with ongoing discussion over whether making ZONE_DMA optional makes sense), a rework of the network time protocol code, the vectored AIO patch set (maybe), a long list of NFS improvements, eCryptfs (though there is some opposition here), various device mapper and RAID improvements, and a number of changes to the generic IRQ layer.
Additionally, Andrew plans to merge a couple of container-oriented patches: virtualization for the utsname and IPC namespaces. Says Andrew:
Normally I'd just buffer all the functionality into -mm until it's ready to go and is actually useful to userspace. But for this work that would mean just too many patches held for too long. So I'll start moving little pieces like this into mainline.
One thing which is not likely to go in is reiser4, which is still held up on various needed fixes. So this filesystem looks like it will wait for yet another development cycle.
Driver core API changes for 2.6.19
The Linux driver core subsystem continues to evolve at a high rate. The set of patches for 2.6.19 continues this process with a number of improvements - and a number of API changes. This time around, however, the changes appear to be additive, and thus should not break any existing drivers.Linux boot time is an ongoing sore point - there are few users who wish that their systems would take longer to come up. There are many things which happen during the boot process, and many possible ways of speeding things up. Most of the opportunities for improving boot time lie in user space, but, on the kernel side, probing for devices can take a lot of time. Each device must be located, initialized, and hooked into the system; this process can involve waiting for peripheral processors to boot, firmware loads, and, perhaps, even physical processes like spinning up disks. As a result, much of the kernel time spent bringing up devices is idle time, waiting for the device to do its part.
One obvious idea for improving this process is to probe devices in parallel. That way, when the kernel is waiting for one device to respond, it can be setting up another; the kernel would also be able to make full use of multiprocessor systems. The 2.6.19 device core will, at last, have the ability to operate in this mode. The changes start by adding a flag (multithread_probe) to the device_driver structure. At probe time, if a driver has set that flag, the actual work of setting up the device will be pushed into a separate kernel thread which can run in parallel with all the others. At the end of the initialization process, the kernel waits for all outstanding probe threads to finish before mounting the root filesystem and starting up user space.
On uniprocessor systems, this change leads to a relatively small reduction of bootstrap time. Drivers typically do not yield the processor during the probe process, so there is relatively little opportunity for parallelism, even during times when the kernel has to wait for a bit. On multiprocessor systems, however, the effect can be rather more pronounced - each CPU can be probing devices in parallel with all the others. So this change will be most useful on large systems with lots of attached devices.
At least, it will be useful once it's enabled; this feature is currently marked "experimental" and carries a number of warnings. Even when it is turned on, it only applies to PCI devices. Not all drivers are written with parallel probing in mind, so they may not have the right sort of locking in place. There can be problems with power drain - turning on too many devices simultaneously can cause a high demand for power over a short period of time; if this demand exceeds what the power supply can deliver, the resulting conflagration could slow the boot process considerably. The order of device enumeration is likely to become less deterministic. And so on. Still, this feature, over time, should lead to faster system boots, especially on systems (such as embedded applications) where the mix of hardware is well understood and static.
On a separate front, the API for handling suspend and resume has been filled out somewhat. The class mechanism now has its own hooks, found in struct class:
int (*suspend)(struct device *dev, pm_message_t state);
int (*resume)(struct device *dev);
The new suspend() method is called relatively early in the suspend process, and is expected to handle any class-specific tasks. These might include quieting the device and stopping higher-level processing. The resume() method is called toward the end of the resume process and should finish the job of getting devices in the class ready to operate again.
Most of the suspend/resume processing is still handled through the bus subsystem, however. That portion of the API has been filled out with three new struct bus_type methods:
int (*suspend_prepare)(struct device *dev, pm_message_t state);
int (*suspend_late)(struct device *dev, pm_message_t state);
int (*resume_early)(struct device *dev);
All of these methods just add more places for the bus code to hook into the process and do whatever work needs to be done. So suspend_prepare() is called early on, while the system is still in an operational state. The suspend() method is unchanged from prior kernels: it is called after tasks have been frozen, and is allowed to sleep if need be. The new suspend_late() method, instead, is called very late, with interrupts disabled and only a single processor running. At resume time, resume_early() is called, once again, with interrupts and SMP disabled, and the old resume() method is called later.
The PCI subsystem makes this new functionality available via three new methods in the pci_driver structure:
int (*suspend_prepare) (struct pci_dev *dev, pm_message_t state);
int (*suspend_late) (struct pci_dev *dev, pm_message_t state);
int (*resume_early) (struct pci_dev *dev);
There are no drivers actually using these new methods in the mainline, as of this writing.
Finally, the class subsystem continues to migrate toward the eventual removal of the class_device structure. To that end, struct class has picked up another pair of methods:
int (*dev_uevent)(struct device *dev, char **envp, int num_envp,
char *buffer, int buffer_size);
void (*dev_release)(struct device *dev);
These methods provide similar functionality as the uevent() and release methods in struct class_device.
Also as part of this migration, a couple of new helper functions have been added:
int device_create_bin_file(struct device *dev,
struct bin_attribute *attr);
void device_remove_bin_file(struct device *dev,
struct bin_attribute *attr);
This methods will let drivers create binary attributes in sysfs without having to deal with the sysfs code directly.
Read-copy-update for realtime
The developers working on realtime response for Linux have stated their intent to merge many of their remaining changes into 2.6.19. One of those changes is a reworking of the read-copy-update mechanism for lower latencies; this work appears likely to go in regardless of the fate of the rest of the realtime code. So it's worth a look.RCU, remember, is a mechanism which allows certain types of data structure to be updated without requiring locking between readers and writers. It works by splitting the update process into two steps: (1) replacing a pointer to old data with a pointer to the updated version, and (2) deferring the removal of the old data structure until it is known that no kernel code holds any references to that structure. The part about knowing that no references are held is handled by (1) requiring all code which references RCU-protected data structures to be atomic, and (2) waiting until all processors have scheduled once. Since a processor which schedules is not running atomic code, it cannot hold any references to RCU-protected data structures from before the call to schedule().
This mechanism works well for most systems, but it presents a problem in realtime environments. The requirement that references to RCU-protected data structures be handled by atomic code means that any such code cannot be preempted. That, in turn, increases latencies, which is just what the realtime code is trying to avoid. So another solution had to be found. A couple of ideas have been pursued, one of which is now advanced to the point that it will likely find its way into 2.6.19. Here we'll take a superficial look at how realtime RCU works; anybody interested in the details is advised to have a look at the realtime RCU paper [PDF] from the 2006 Ottawa Linux Symposium.
Fixing the RCU latency problem means ending the requirement that RCU-protected code be non-preemptible. And that, in turn, means that RCU can no longer count on a processor rescheduling meaning that no references to RCU-protected structures exist on that processor. So the accounting must be done in a more explicit manner. The realtime RCU code handles this accounting with two sequence numbers, two per-CPU counters and three linked lists.
The sequence numbers track the specific batches of RCU callbacks to process; for added confusion value, both are named "completed," though they live in two different global structures. The value rcu_ctrlblk.completed is the current batch number, which is accumulating new callbacks to process; rcu_data.completed, instead, is the number of the last batch of callbacks to have been processed.
Within any given RCU batch, one of the per-CPU counters tracks the number of kernel threads which are currently executing within RCU critical sections. During this batch, any RCU callbacks queued (with call_rcu()) will be appended to the first of the linked lists: rcu_data.nextlist. Whenever code calls rcu_read_lock(), the appropriate counter is incremented; a pointer to that counter is also stored so that, should the thread change processors before calling rcu_read_unlock(), the right counter will be decremented.
Another reason for storing a pointer to the counter has to do with the batch "flip" logic. When the RCU code decides that it is time to start a new batch, it increments rcu_ctrlblk.completed; that, in turn, will cause rcu_read_lock() to switch to the second per-CPU counter, which will start out at zero. Any new entries into RCU critical sections will increment the new counter. Meanwhile, any code which was in such a section when the flip happened retains a pointer to the old counter. So, when that code calls rcu_read_unlock(), the older counter will be decremented. When all of the counters from the old batch reach zero, the kernel knows that all references to RCU-protected data from the old batch are gone, and the corresponding RCU callbacks can be called.
Also at flip time, the set of RCU callbacks in rcu_data.nextlist is moved over to rcu_data.waitlist, since those callbacks are now waiting for any possible remaining references to go away. When all of the counters for that batch drop to zero, these callbacks are moved to the third list (rcu_data.donelist) so that they can be invoked whenever the kernel decides to get around to it. That work currently happens in a tasklet, but there is another patch queued for 2.6.19 which moves that work over to a separate software interrupt handler.
With this code in place, code within an RCU critical section can be preempted and it will still be possible to know when all references to protected data structures are gone. RCU critical sections still cannot sleep, of course, or they could delay the batch flip indefinitely. But they can be pushed out of the way temporarily if a higher-priority process needs to run.
The overall overhead of the new mechanism is higher, however, since it must maintain all of those counters. For this reason, it is unlikely to ever be the default RCU on most systems. Instead, the plan is to ship two RCU implementations, "classic" and "preempt," and allow the person configuring the kernel to choose between them.

Debian + Dunc-Tank.org = dissent
Last week's announcement of Dunc-Tank.org set off flame wars and controversy on Debian mailing lists including a rash of general resolutions and a post from the Project Secretary on the procedure for proposing and sponsoring General resolutions. It even had Linux-Watching wondering, 'Is Debian is dying?'.The Dunc-Tank.org is described as "fund-raising experiment" with the initial goal of raising funds to pay Debian release managers Steve Langasek and Andreas Barth to work full time on the Debian Etch release, for a period of one month each. This project is independent of the Debian Project, however the Dunc board is made up of prominent Debian Developers including current Debian Project Leader Anthony Towns and his assistant DPL Steve McIntyre.
Therein comes the controversy. If the DPL is involved, doesn't that make it a Debian Project? Can the DPL remain objective and unbiased while working on Debian and an organization. Should Debian Developers be paid to do work on Debian?
The goal is to release Etch on schedule, which is December 4, 2006. The Debian Project and the Dunc-Tank share that goal. People will argue about how that should be achieved, but there's general agreement on the goal. If independent companies share that goal and want to help out in some fashion their assistance should be appreciated. The DPL should ensure that any help accepted from independent companies does not somehow compromise Debian. If the DPL is also the CEO of the independent company that is offering its assistance, there could be a conflict of interest. In this case Anthony has started an organization that he hopes will be able to help Debian. Dunc-Tank is an experiment which may or may not be effective. If Etch is released on schedule and Dunc-Tank helps with that goal, then every one should be can be happy about achieving that goal. If it fails Dunc-Tank won't have much of a future.
Should Debian Developers, who are all volunteers, ever be paid to work on Debian? In fact many Debian Developers have found gainful employment that allows them to work on Debian as part of their job. Companies who use Debian internally or have based their products on Debian, such as HP, Canonical, Progeny, etc., employ Debian Developers and expect them to work on Debian during company time. For the most part DDs who find such employment are encouraged, applauded, and occasionally envied, but are generally not accused of having a conflict of interest. If the release managers don't have to worry about making a living while devoting their time to the Etch release it just might help Etch go out on time.
In spite of the resolution calling for the recall of Anthony Towns as DPL, it would seem that Anthony has a fair amount of support from the developers. Anthony has offered to step down if that's what people really want, but having him step down at this point won't help Etch release on time and it may ensure that the release is hopelessly delayed.
The recall proposal would require two weeks of discussion followed by another two weeks of voting. If the resolution passed another project leader election would start immediately with nine weeks of nominating, campaigning and voting. Could Etch still be released on time with that going on? Maybe, I think most DDs would rather concentrate on the release. If Dunc-Tank proves an absysmal failure then there will still be time to oust Anthony before his term as DPL is over.

Debian announcements
Christian Aichinger introduces a plan to get rid of unnecessary package dependencies. "[U]nnecessary dependencies cause lots of problems, as they make transitions bigger then they need to be. The root cause are unnecessary libraries on the linker commandline, which get stored in the resulting binary and which dpkg-shlibdeps happily turns into inter-package dependencies."
The results for the Constitutional General
Resolution concerning the handlings of assets has been approved. "At
the end of voting, with 344 Ballots resulting in 266 votes from 266

The DistroWatch Weekly for September 25, 2006 is out. "With Mandriva Linux 2007 and Slackware Linux 11.0 expected any time now, and Ubuntu 6.10 beta also scheduled for release later this week, the next few days are likely to provide enough excitement to keep all "distro watchers" busy with brand new products. But will Debian GNU/Linux 4.0 "etch" be on time too? A highly controversial way of making that happen has stirred the Debian developer community to the point that some of them are calling for the removal of the project's elected leader! In other news, we report about a new init system for Fedora Core, a graphical Xgl/Compiz configuration tool for openSUSE, and a new distribution designed for those who just can't leave their previous desktop interface behind. A "First Look" section featuring SabayonLinux 3.0 is then followed by several statistical reports indicating that your interest in DistroWatch and open source operating systems have been increasing at a rather phenomenal rate."

Nothing about Freespire 1.0 is particularly deficient (and as far as I could tell, nothing major is broken), but it has a lot of growing to do before it truly sets itself apart from its competition."

Development
XCB: the X Protocol C Binding
The XCB project aims to replace the Xlib interface to the X Window System:
Bart Massey and Jamey Sharp originally described XCB in a 2001 paper entitled: An X Protocol C Binding [PDF]. The XCB project history gives a look at some important project milestones and lists the tasks that have been completed to date.
The XCB project aims to improve on a number of Xlib weaknesses. Some of the XCB features include:
- A smaller memory footprint than Xlib.
- Support for latency hiding to address Xlib speed issues.
- Support for partial emulation of the Xlib API.
- Support for direct access to the X protocol.
- Support for the addition of new X extensions.
- Thread support designed from the beginning, not added-on like Xlib.
- Built on top of an XML description (xcb-proto) of the core X protocol.
- Development of the Xlib Compatibility Layer (XCL) for running legacy applications.
Other changes in this release include: a new API naming convention, new include directory conventions, an improved error handling plan, a more resilient connection error handling system, removal of deprecated functions, a split of the GIT repository, and bug fixes.
For more information on XCB, see the XCB API definition, the XCB Tutorial, the XCB Developer's Guide and other publications on XCB.

Plans for gnome-vfs replacement (GnomeDesktop)
GnomeDesktop follows a thread by Alexander Larsson concerning a gnome-vfs overhaul. "Recently there has been a lot of discussions about the gnome platform and the correct stacking order and quality of the modules. Gnome-vfs is a clear problem in this discussion. Having spent the last 4 years as the gnome-vfs maintainer, and even longer as the primary gnome-vfs user (in Nautilus) I'm well aware of the problems it has. I think that we've reached a point where the problems in the gnome-vfs architecture and its position in the stack are now ranking as one of the most problematic aspects of the gnome platform, especially considering the enhancements and quality improvements seen in other parts of the platform."

Torvalds has frequently criticized the process and the drafts of the GPLv3, and recently voted against the license in an informal poll of kernel developers, so it seems obvious to question why he chose to sit out the process. Torvalds gives his reasons as a dislike of committees, an inability to contribute in his preferred way, and philosophical differences with the Free Software Foundation (FSF), which he suggests is trying to absorb other licenses under the GPL."

What Would You Like to Ask Open Invention Network CEO Jerry Rosenthal? (Groklaw)
Groklaw is looking for a few good questions. "A lot of legal brainpower has been going into trying to figure out solutions to the patent threat hanging in the air. We all assume that Microsoft will kill Linux if it can ever find a way, and heaven only knows Steve Ballmer has made veiled threats about using patents. Lawyers on the Linux side understand that language and some real creativity has gone into devising some ways to block, such as the OSDL's patent commons and FOSS search engine project to make it easier for the USPTO to find FOSS prior art and NYU's Open Source prior art project. I believe these are helpful projects. One of the most creative ideas, in my view, is the Open Invention Network, which launched in November of 2005. I know some of you have issues with any strategy that involves patents, so I asked OIN'S CEO Jerry Rosenthal if he would answer your questions, and he has agreed. It's an opportunity to get a firm grasp of what the strategy is, how it is working or not, and what the future might be."

David DeJean looks at IBM's Linux Client Migration Cookbook, Version 2 in a ComputerWorld blog. "I must own half a dozen volumes devoted to leaving Microsoft operating systems behind and converting to Linux. For me it's the same sort of fantasy as people who buy travel guides and dream of moving to Bali. Someday, I keep promising myself, I'm really going to do it. The latest book in my collection is the biggest yet. In fact, if it were printed it would probably outweigh an old Sears wish book. Fortunately, it's a PDF file, but at 339 pages its still a tome. But I mean that in a good way.""

Website Review: The Family Guide to Digital Freedom (Linux Journal)
Bruce Byfield reviews the Family Guide to Digital Freedom website. "The Family Guide to Digital Freedom is a website and an accompanying book created by Marco Fioretti, a part-time journalist who writes about free and open source software (FOSS). The site is interesting for its attempt to do things at once: to provide a guide for non-technically inclined computers users to the advantages of open standards and free software, and a critique of the FOSS communities. Both goals are overdue for widespread attention, although they sometimes sit uncomfortably beside each other on Fioretti's site."
Good bits in GNOME 2.16 (Linux.com)
Linux.com reviews GNOME 2.16. "The GNOME Project recently released GNOME 2.16. While the latest release doesn't offer any breakthrough features, it does include a wealth of minor tweaks and improvements. Ironically, the most intriguing improvement is the one you probably won't notice, unless you explicitly enable it. Metacity, GNOME's default window manager, now features several 3-D extensions to its composite engine. These extensions allow you to add some eye candy to your desktop by enabling window effects and different types of transparency. This feature is not enabled by default, though, and you have to compile Metacity with the --enable-compositor option to get it to work. For the time being, the new compositing effects can only be used with a handful of graphics cards."
Review: Mesk Audio Player 0.2.1 (polishlinux.org)
polishlinux.org reviews the Mesk Audio Player. "There are numerous audio players designed especially for GNOME. Single GnomeFiles repository lists over 60 of them. However, the problem lays in quality rather than quantity. Recently Ive been looking for an audio player that would resemble the famous Windows player called Foobar 2000. I have found a lot of clones, and just a few original applications. Mesk audio player was among the latter."
First look: Scalix 11 Community Edition messaging server (Linux.com)
Linux.com previews the new open source Scalix 11 Community Edition messaging server. "While the release of the new open source Scalix 11 Community Edition messaging server is still a few months away, the binaries have been brought out in a preview package that is, according to the license that comes with it, "pre-release software with known issues and is not suitable for production use." We tried it out, just to see where Scalix is heading. The good news -- it's heading in the right direction for small and medium-sized businesses."
Smalltalk for Everyone Else (O'ReillyNet)
Keith Fieldhouse takes a look at Smalltalk and Squeak on O'ReillyNet. "Smalltalk, an influential language with deep roots in software development practice, offers an outstanding opportunity for stretching your mind and exercising your development muscles. The only drawback is that once you try it, you may never go back. This article will help you get started."

Another GPL win in Germany
The gpl-violations.org project has announced that it has won a court case against D-Link in Germany. "On September 6, 2006 the district court issued its judgement, confirming the claims by gpl-violations.org, specifically its rights on the subject-matter source code, the violation of the GNU GPL by D-Link, the validity of the GPL under German law, and D-Link's obligation to reimburse gpl-violations.org for legal expenses, test purchase and cost of re-engineering." (Thanks to Atul Chitnis).
An update from One Laptop Per Child
Christopher Blizzard, who heads up Red Hat's contributions to the One Laptop Per Child project, has posted an update on the status of the project. "One of the areas that's under heavy discussion right now is around the use of crypto on the laptop. This includes the use of signing for messages between the laptops and signing of software itself. We have neither made choices about what libraries we want or what the exact role will be for all these bits, but we are exploring the goals for which crypto plays a role." (Thanks to Rahul Sundaram).
Commercial announcements
Eric Raymond Joins Freespire
Eric Raymond's remarks on support for proprietary codecs has led a number of people to suggest that he should be working with Linspire instead of a fully-free distribution. He appears to have heard: Linspire has announced that Mr. Raymond has joined the "Freespire leadership board." "In recent weeks, Raymond has surprised many by speaking publicly about the 'necessary compromise' that open source advocates must be willing to make, by providing for an easy way for open source software to work with key proprietary technologies for which there are not yet adequate open source alternatives. Freespire is the most prominent desktop Linux distribution to embrace this concept."
InfiniBand Trade Association Ratifies iSER Storage Protocol
The InfiniBand Trade Association has ratified the iSER (iSCSI RDMA) Storage Protocol for InfiniBand. "The InfiniBand Trade Association today announced that it has released a new annex to the specification providing support for iSER over Infiniband. The iSER annex extends InfiniBand's support for high performance storage. At 10-20 Gbps bitrates, InfiniBand's performance is now more than triple that of FibreChannel, and at only half the cost. Subsequently, InfiniBand has six times the price performance advantage of FibreChannel. iSER is a new IETF standard extension to iSCSI that includes support for RDMA-enabled networks such as InfiniBand; the new annex closes the loop by mapping the iSER extensions onto InfiniBand."
Link Linux Shares to Trade Publicly

That means Novell will provide technical support for the Xen hypervisor if a customer uncovers an issue running a virtual instance of Red Hat Linux and that issue is not reproducible in a native, or non-virtualized, environment."
