Giving Greylisting A Try
by Lawrence D'Oliveiro 15 Jul '19

15 Jul '19

I have decided to try installing sqlgrey on my VPS to see if that cuts down on the volume of spam. The basic idea is more than a decade old, and I can’t find much in the way of newer testimonials as to how wonderful it continues to be. On the other hand, I can’t see anyone saying it is now a terrible idea that should have a stake put through its heart and buried in an unmarked grave at midnight and forgotten. (Actually I’m posting this message just to see how legitimate mail makes it through the greylist obstacle course; it’s only been running less than an hour, and has already blocked 10 spam messages so far.)

What Does Ubuntu's Post-Unity Future Look Like?
by Peter Reutemann 14 Jul '19

14 Jul '19

'Following Canonical's pivot away from its internally-developed Unity user interface and Mir display server, Ubuntu has enjoyed two relatively low-drama years, as the Linux Desktop market homogenized during its transition back to a customized GNOME desktop. In a review of the most recent release, TechRepublic's Jack Wallen declared that "Ubuntu 19.04 should seriously impress anyone looking for a fast and reliable Linux desktop platform." Largely, it's been a slow-and-steady pace for Ubuntu since the pivot from Unity to GNOME, though the distribution made headlines for plans to end support for 32-bit support. This prompted Valve, operators of games marketplace Steam, to re-think its approach toward Ubuntu, which it previously characterized as "as the best-supported path for desktop users." TechRepublic's James Sanders interviewed Will Cooke, director of engineering for Ubuntu Desktop at Canonical, about the distribution's long-term plans for legacy 32-bit support, shipping a desktop in a post-Unity-era Ubuntu, and why Linux should be the first choice for users migrating from Windows 7 prior to the end of support. >From the interview: When we did the switch to GNOME Shell from Unity, we did a survey [asking] people straightforward questions like, "What sort of features do you want to see continue in Ubuntu Desktop?" The answer came through very, very clearly that people liked having the launcher on the left, and they wanted to keep that feature there. They liked having desktop icons and they wanted to keep that feature there. We've made decisions based on data from our user base, from our community. They have provided that feedback and we've done what the majority of people want. Sometimes that doesn't go with the ideals of GNOME design, but we're comfortable with delivering what we see as value on top of GNOME. That's delivering a product which gives people consistency between the old days of Unity 7, and the new days of GNOME Shell. That transition was as easy as possible, everybody had a chance to have a say in it, and the answers were pretty clear.

What's New in Linux 5.2?
by Peter Reutemann 14 Jul '19

14 Jul '19

'Linux 5.2 has been released. This release includes Sound Open Firmware, a project that brings open source firmware to DSP audio devices; open firmware for many Intel products is also included. This release also improves the Pressure Stall Information resource monitoring to make it usable by Android; the mount API has been redesigned with new syscalls; the BFQ I/O scheduler has gained some performance improvements; a new CLONE_PIDFD flag lets clone(2) return pidfs usable by pidfd_send_signal(2); Ext4 has gained support for case-insensitive name lookups; there is also a new device mapper target that simulates a device that has failing sectors and/or read failures; open source drivers for the ARM Mali t4xx and newer 6xx/7xx have been added. Many other new drivers, features and changes can be found in the changelog. But there's more besides supporting "a handful of extra ARM-powered single-board computers," according to CRN: The biggest feature in 5.2 is probably support for Intel's forthcoming Comet Lake architecture, which will power the tenth generation of its Core desktop and mobile CPUs due. The new silicon is due to ship late in 2019 and appear in products early the next year. Linux 5.2 also includes many tweaks that improve its performance on laptops.' -- source: https://linux.slashdot.org/story/19/07/13/0436246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Patches Two New Security Flaws
by Peter Reutemann 14 Jul '19

14 Jul '19

'This week Intel announced two new patches, according to Tom's Hardware: The flaw in the processor diagnostic tool (CVE-2019-11133) is rated 8.2 out 10 on the CVSS 3.0 scale, making it a high-severity vulnerability. The flaw [found by security researcher Jesse Michael from Eclypsium] "may allow an authenticated user to potentially enable escalation of privilege, information disclosure or denial of service via local access," according to Intel's latest security advisory. Versions of the tool that are older than 4.1.2.24 are affected. The second vulnerability, found by Intel's internal team, is a medium-severity vulnerability in Intel's SSD DC S4500/S4600 series sold to data center customers. The flaw found in the SSD firmware versions older than SCV10150 obtained a 5.3 score on the CVSS 3.0 scale, so it was labeled medium-severity. The bug may allow an unprivileged user to enable privilege escalation via physical access. As one of the flaws was uncovered by Intel itself and for the other the Eclypsium research coordinated with Intel for its disclosure, Intel was able to have ready the patches in time for the public announcement.

PC Sales Are Up--Or Are They?
by Lawrence D'Oliveiro 12 Jul '19

12 Jul '19

Another report highlighting the usual discrepancy in analysis of PC sales between IDC and Gartner <https://arstechnica.com/information-technology/2019/07/gartner-idc-agree-th…>: the difference seems down to the fact that one includes Chromebooks in their definition of a “PC”, while the other one counts Microsoft Surface tablets instead. Obvious conclusion: if it weren’t for Chromebooks, the PC market would be a pretty gloomy place indeed.

The Most Clever 'Zip Bomb' Ever Made Explodes a 46MB File To 4.5 Petabytes
by Peter Reutemann 11 Jul '19

11 Jul '19

'Programmer and engineer David Fifield has unveiled a brand-new Zip bomb that explodes a 46-megabyte file to 4.5 petabytes of data. Fifield's new type of "Zip bomb" or "compression bomb" is particularly novel because he "figured out how to 'overlap' files inside of a Zip archive, allowing for compression rates far beyond those of a traditional archive," reports Motherboard. From the report: In an email interview, Fifield noted that, while 42.zip (which has a 106 billion-to-one compression ratio and has been hosted on the same single-serving website for at least 15 years) gets much of the attention, he finds later attempts more technically interesting. "eI find 42.zip inspiring on an aesthetic level -- not so much the file itself but the circumstances around it," Fifield said. "It's like folklore. There must have been many examples of the same basic idea, but for whatever reason 42.zip is the one that had staying power." Fifield noted that part of what makes his process possible was by coming up with ways to handle cyclic redundancy checks, or CRCs, a basic error-correction functionality baked into Zip, PNG, Ethernet, and numerous other technical standards. Messing around with CRC -- 32 checksums, as they're called, was where Fifield said he learned the most. Fifield, who will present his findings at the USENIX Workshop on Offensive Technologies (WOOT) conference next month, noted that while the work itself adds to a history of research and likely will be superseded in the future, its benefit from an awareness standpoint is importan' -- source: https://hardware.slashdot.org/story/19/07/10/2341251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
