FreeBSD 7.0 Bests Linux In SMP Performance 288

Posted by kdawson from the coulda-been-a-contender dept.
cecom writes "After major improvements in SMP support in FreeBSD 7.0, benchmarks show it performing 15% better than the latest Linux kernels (PDF, see slides 17 to 19) on 8 CPUs under PostgreSQL and MySQL. While a couple of benchmarks are not conclusive evidence, it can be assumed that FreeBSD will once again be a serious performance contender. Some posters on LWN have noted that the level of Linux performance could be related to the Completely Fair Scheduler, which was merged into the 2.6.23 Linux kernel." Update: 03/06 21:32 GMT by KD : An anonymous reader sent in word that Linux kernel developer Nick Piggin reran the benchmark today and came to a different conclusion: In his benchmark Linux was faster than FreeBSD.

What's New In FreeBSD 7.0 103

Posted by kdawson from the what-indeed dept.
blackbearnh writes "FreeBSD is about to release the much-anticipated version 7, and as usual there's a comprehensive interview with over two dozen of the major contributors over at O'Reilly's ONLamp site. Federico Biancuzzi interviewed the developers to discuss all the details of FreeBSD 7.0: networking and SMP performance, SCTP support, the new IPSEC stack, virtualization, monitoring frameworks, ports, storage limits and a new journaling facility, what changed in the accounting file format, jemalloc(), ULE, and more."

OpenBSD Will Not Fix PRNG Weakness 196

Posted by kdawson from the random-acts-of-kndness dept.
snake-oil-security writes "Last fall Amit Klein found a serious weakness in the OpenBSD PRNG (pseudo-random number generator), which allows an attacker to predict the next DNS transaction ID. The same flavor of this PRNG is used in other places like the OpenBSD kernel network stack. Several other BSD operating systems copied the OpenBSD code for their own PRNG, so they're vulnerable too; Apple's Darwin-based Mac OS X and Mac OS X Server, and also NetBSD, FreeBSD, and DragonFlyBSD. All the above-mentioned vendors were contacted in November 2007. FreeBSD, NetBSD, and DragonFlyBSD committed a fix to their respective source code trees, Apple refused to provide any schedule for a fix, but OpenBSD decided not to fix it. OpenBSD's coordinator stated, in an email, that OpenBSD is completely uninterested in the problem and that the problem is completely irrelevant in the real world. This was highlighted recently when Amit Klein posted to the BugTraq list."

NetBSD 4.0 Has Been Released 121

Posted by ScuttleMonkey from the so-long-and-thanks-for-all-the-stacks dept.
ci4 writes to tell us that NetBSD 4.0 has been released and has been dedicated to the memory of Jun-Ichiro "itojun" Hagino. "Itojun was a member of the KAME project, which provided IPv6 and IPsec support; he was also a member of the NetBSD core team (the technical management for the project), and one of the Security Officers. Due to Itojun's efforts, NetBSD was the first open source operating system with a production ready IPv6 networking stack, which was included in the base system before many people knew what IPv6 was. We are grateful to have known and worked with Itojun, and we know that he will be missed. This release is therefore dedicated, with thanks, to his memory."

What's New in OpenBSD 4.2? 203

Posted by Zonk from the new-footloose-and-fancy-free dept.
blackbearnh writes "OpenBSD 4.2 was released today, and has a host of new features. O'Reilly's ONLamp site has a pretty thorough overview of the release. 'Even though security is still there, this release comes with some amazing performance improvements: basic benchmarks showed PF being twice as fast, a rewrite of the TLB shootdown code for i386 and amd64 cut the time to do a full package build by 20 percent (mostly because all the forks in configure scripts have become much cheaper), and the improved frequency scaling on MP systems can help save nearly 20 percent of battery power. And then the new features: FFS2, support for the Advanced Host Controller Interface, IP balancing in CARP, layer 7 manipulation with hoststated, Xenocara, and more!'"

Virtualization Decreases Security 340

Posted by kdawson from the more-chances-to-blow-it dept.
ParaFan writes "In a fascinating story on KernelTrap, Theo de Raadt asserts that while virtualization can increase hardware utilization, it does not in any way improve security. In fact, he contends the exact opposite is true: 'You are absolutely deluded, if not stupid, if you think that a worldwide collection of software engineers who can't write operating systems or applications without security holes, can then turn around and suddenly write virtualization layers without security holes.' de Raadt argues that the lack of support for process isolation on x86 hardware combined with numerous bugs in the architecture are a formula for virtualization decreasing overall security, not increasing it."

GCC Compiler Finally Supplanted by PCC? 546

Posted by ScuttleMonkey from the all-good-things-must-end dept.
Sunnz writes "The leaner, lighter, faster, and most importantly, BSD Licensed, Compiler PCC has been imported into OpenBSD's CVS and NetBSD's pkgsrc. The compiler is based on the original Portable C Compiler by S. C. Johnson, written in the late 70's. Even though much of the compiler has been rewritten, some of the basics still remain. It is currently not bug-free, but it compiles on x86 platform, and work is being done on it to take on GCC's job."

Software Freedom Law Center vs Theo de Raadt 464

Posted by Zonk from the steady-now-steady dept.
An anonymous reader writes "In a recent public posting to the Linux Kernel mailing list the founder of the Software Freedom Law Center, Eben Moglen, lashed back at OpenBSD creator Theo de Raadt without actually mentioning his name. 'What has happened is that people who do not have full possession of the facts and have no legal expertise — people whom from the very beginning we have been trying to help — have made irresponsible charges and threatened lawsuits, thus slowing down our efforts to help them.' Moglen pointed out that they have and continue to help all open source projects, including OpenBSD, but the process takes time. 'The required work has been made more arduous because some people have chosen not to cooperate in good faith. But we will complete the work as soon as we can, and we will follow the community's practice of complete publication, so everyone can see all the evidence.'"

Theo de Raadt On Relicensing BSD Code 613

Posted by kdawson from the read-the-berne-convention dept.
iBSD writes "KernelTrap has an interesting article in which Theo de Raadt discusses the legal implications of the recent relicensing of OpenBSD's BSD-licensed Atheros driver under the GPL. De Raadt says, 'it has been like pulling teeth since (most) Linux wireless guys and the SFLC do not wish to admit fault. I think that the Linux wireless guys should really think hard about this problem, how they look, and the legal risks they place upon the future of their source code bodies.' He stressed that the theory that BSD code can simply be relicensed to the GPL without making significant changes to the code is false, adding, 'in their zeal to get the code under their own license, some of these Linux wireless developers have broken copyright law repeatedly. But to even get to the point where they broke copyright law, they had to bypass a whole series of ethical considerations too.'"

Will GPLv3 Drive Users from Linux to FreeBSD? 374

Posted by Zonk from the sad-penguin dept.
An anonymous reader writes "Last week ZDNet put up an article asking a simple question: will GPL3 drive Linux users to FreeBSD? It's based on issues raised in the August FreeBSD Foundation Newsletter. That publication features a letter by the vice president of the FreeBSD Foundation, Justin Gibbs, arguing that the GPLv3 restricts the rights of commercial users of open source software, and is just the FSF's first step in changing the GPL in ways that authors of GPL software may not have intended. He suggests that commercial users should seriously consider BSD-licensed software as an alternative if they want to be able to safely ship products in the future. This is especially in light of requirements from the FCC that software running on devices (such as software-defined radios) be end-user replaceable. Gibbs states that the FreeBSD Foundation will provide an alternative to GPLv3'd software, especially in light of Stallman's statement that further GPL revisions are due in the near future. Is this likely to cause discontent among Linux users, or will they mostly ignore it?"

GPL Hindering Two-Way Code Sharing? 456

Posted by kdawson from the thank-you-and-goodbye dept.
An anonymous reader writes "KernelTrap has some fascinating coverage of the recent rift between the OpenBSD developers and the Linux kernel developers. Proponents of the GPL defend their license for enforcing that their code can always be shared. However in the current debate the GPL is being added to BSD-licensed code, thereby preventing it from being shared back with the original authors of the code. Thus, a share-and-share-alike license is effectively preventing two-way sharing." We discussed an instance of this one-way effect a few days back.

Cambridge Researcher Breaks OpenBSD Systrace 194

Posted by kdawson from the without-a-trace dept.
An anonymous reader writes "University of Cambridge researcher Robert Watson has published a paper at the First USENIX Workshop On Offensive Technology in which he describes serious vulnerabilities in OpenBSD's Systrace, Sudo, Sysjail, the TIS GSWTK framework, and CerbNG. The technique is also effective against many commercially available anti-virus systems. His slides include sample exploit code that bypasses access control, virtualization, and intrusion detection in under 20 lines of C code consisting solely of memcpy() and fork(). Sysjail has now withdrawn their software, recommending against any use, and NetBSD has disabled Systrace by default in their upcoming release."

The review describes the installation process, articulates the advantages of PC-BSD,and reveal some of the challenges that the reviewer faced along the way. From the article: 'In the end, I would suggest this distribution to new users provided they had someone to call in case of a driver malfunction during installation. I would also recommend PC-BSD to seasoned Unix users that have never tried using FreeBSD before and would prefer a shallower learning curve before getting down to business.'"

Closed Source On Linux and BSD? 526

Posted by kdawson from the license-ramification-details dept.
An anonymous reader writes "I want to start (very small) software/hardware business. The code in question will be closed source. I won't modify or use any GPL code or any 3rd-party sources. It will be my own handwritten C/C++ code from start to finish. I am planning to sell embedded-like boxes with an OS (Linux or BSD) and this code. I am more familiar with Linux but I am scared a little bit of Linux licensing, and also of Linux fanboy-ism: I personally got a 'go to hell with your @#$ closed code' slur on Slashdot. I am not a GPL guru and not a software freedom fighter. I just want to do my job and make a living." Read on for this reader's five particular questions.
