FreeBSD: Fix for Hyper-Threading Vuln. Considered Non-Trivial

  Submitted by HassleB0f Privacy, Security 1 Comment
KernelTrap reports: Colin Percival continues the discussion regarding the shared-cache vulnerability inherent in multi-core processors, offering potential mitigation techniques in the form of fixes to the FreeBSD schedulers. Based on Percival's original discovery, information leakage between threads which share a processor core and the subsequent opportunity to monitor memory access patterns can be prevented by eliminating the co-scheduling of threads that have differing privileges.

New CPU from VIA, The C7

  Submitted by Ryan M. Graham Hardware 61 Comments
VIA issued a press release on Friday announcing their new C7 Processor. Noteworthy PVR related features include its low power consumption (2.0GHz at 20W, idle at 0.1W) and support for SSE2 and SSE3 (in addition to existing MMX and SSE support). In the crypto department, they've expanded their PadLock™ hardware crypto/security suite with this CPU by adding in full hardware SHA-1 and SHA-256 (20BGps), hardware assisted RSA (hardware Montgomery Multiplier), a beefed up RNG that feeds directly into the SHA units, and the NX bit.

Balancing Power, Cooling, and Performance

General Development 11 Comments
Power consumption, supply voltage, junction temperature, system cooling requirements, and processor clock rate are all physically and thermodynamically related. By understanding the relationships, system cost and complexity trade-offs, and resource requirements, system designers can strike a better balance between requirements. See how you can incorporate emergent cooling and adaptive power control methods into embedded system designs.

Table of Analogs to Windows Software in Linux

  Submitted by Fiodor Sorex Linux 54 Comments
One of the biggest difficulties in migrating from Windows to Linux is the lack of knowledge about comparable software. Newbies usually search for Linux analogs of Windows software, and advanced Linux-users cannot answer their questions since they may not know much about available Windows software. This list of Linux equivalents / replacements / analogs of Windows software is based on our own experience and on the information obtained from the visitors of this page on English, Russian, Italian, Spanish, French & German.

Microsoft vs Unix: Its a Tie for the First Time

  Submitted by Bob In the News 32 Comments
The Financial Express reports that, for the first time, sales of servers running Windows matched the revenues of Unix servers: Revenue for Windows servers grew 12.3 per cent to $4.2 billion in the quarter while unit shipments grew 10.7 per cent. Unix servers saw 2.8 per cent revenue growth to $4.2 billion while unit shipments increased 5 per cent. HP made gains on leader IBM, Dell posted huge growth, and Linux made up an ever larger share. It appears that both Windows and Linux continue to chip away at proprietary Unix from both ends.

No ELF Vulnerability in Linux Kernel (Updated)

Privacy, Security 44 Comments
Update: It appears that we mischaracterized the conclusions in our title and our summary on this story. Greg KH was referring only to the ELF vulnerability in this story. Whether we were deliberately mislead by the submitter of this story or not, we regret the error.

The original story: According to "Greg KH," co-maintainer of the 2.6.x.y series of important stability and security fixes, the Linux kernel does not suffer from the much-hyped hyper threading vulnerability that affected the BSDs: " The main reason there have not been any updates, is that there really isn't a problem for the 2.6 kernel. The original author has admited this finally, no one was ever able to reproduce it on a 2.6 kernel. The only reason I released a kernel update, was at the time, we thought there was an off-chance that there was a problem. However in further testing, it has not been the case." This confirms Linus's earler assertion.

Intel Adds DRM to Chips

  Submitted by David Intel 101 Comments
If you though the subject of DRM and Trusted Comouting had gone away, think again. Intel is adding DRM capabilities to its new Pentium D chipsets, but as with AMD, they're not that keen on talking about it. Aside from DRM, there's also this gem: Additionally, AMT also features what Intel calls "IDE redirection"...allow administrators to remotely enable, disable or format or configure individual drives and reload operating systems and software from remote locations, again independent of operating systems.

Mac OS X 10.4 ‘Tiger’ in depth

macOS 17 Comments
"Review I've been running Mac OS X 'Tiger' since the day after its release, on 29 April. At the time, hundreds of reviews of the operating system were published, but I didn't want to be a part of the herd, since many of them were little more than lists of the new features. I wanted to spend some more time with Tiger before getting off the fence." Read the article at TheRegister.
