FFmpeg 7.0 “Dijkstra”: Best New Features
by Peter Reutemann 19 Apr '24

19 Apr '24

'One of the major updates in FFmpeg 7.0 is the parallel execution of operations for unpacking/packing media containers, decoding, encoding, and applying filters using the ffmpeg command line utility. This feature allows for the simultaneous execution of multiple tasks, resulting in a significant improvement in performance and efficiency, particularly when working with large-scale multimedia projects. Another notable addition is the support for encoding and decoding video in MPEG-5 format (EVC – Essential Video Coding) using the external library libxevd. This new format provides high efficiency transmission and storage of all screen resolutions, supports video with an extended dynamic range (HDR), and panoramic video in 360-degree mode. In addition, FFmpeg 7.0 has added unpackers and packers of media containers (demuxer/muxer) for the QOA (Quite OK Audio) format, which is used for transmitting audio with loss of quality. QOA decoding is claimed to be three times faster than Ogg-Vorbis while achieving higher quality and compression levels compared to ADPCM. The new version also includes unpackers and packers of media containers (demuxer/muxer) for the IAMF (Immersive Audio Model and Format) format, which defines a container for distributing surround sound. The format provides for the transmission of additional information necessary for the operation of sound stage reconstruction and sound mixing algorithms, and takes into account the propagation of sound signals in three-dimensional space to recreate sound as close to natural as possible. An experimental decoder for the VVC (Versatile Video Coding) format, also known as the H.266 video compression standard, has been added in FFmpeg 7.0. This new format provides high efficiency transmission and storage of all screen resolutions, supports video with an extended dynamic range (HDR), and panoramic video in 360-degree mode. The ffplay utility has added support for hardware acceleration of decoding using the Vulkan and libplacebo APIs, and the ability to use API D3D12VA (Direct 3D 12 Video Encoding) for hardware acceleration of decoding of H264, HEVC, VP9, AV1, MPEG-2 and VC1 formats has been implemented. [...] Remember: This version is NOT backward compatible. That means, many CLI options and API are removed which are long deprecated. So use caution before upgrading to version 7.0.' -- source: https://www.debugpoint.com/ffmpeg-7-0-features/ Cheers, Peter -- My Open Source Blog - http://open.fracpete.org

High Priority PuTTY Vulnerability Threatens Server Access Security
by Peter Reutemann 19 Apr '24

19 Apr '24

'A critical security vulnerability in PuTTY, a very popular software for secure terminal access to remote servers, has been discovered. This vulnerability could put the private keys of many users at risk. Cataloged as CVE-2024-31497, the vulnerability affects PuTTY version numbers between 0.68 and 0.80. So, if you have been using PuTTY during this time, it is important to be aware of what this means for your data security. Fabian Bäumer and Marcus Brinkmann of the Ruhr University Bochum found the vulnerability. It concerns how PuTTY forms signatures from the ECDSA private keys on the NIST P521 curve. The vulnerability with PuTTY is that it creates a component of the signature called ‘nonce’ during the generation process. This randomly generated number can be used once in a cryptographic communication, thus ensuring that old communications cannot be reused in replay attacks. However, PuTTY used a deterministic method to generate nonces due to the lack of a high-quality random number generator in early Windows systems. This deterministic method was biased for the P521 curve, which made the private key recovery possible. Simply put, an attacker who gets hold of multiple signed messages can potentially recover your private key due to a specific bias in the signature creation process. This would allow them to forge signatures and access any servers where you’ve used this key.' -- source: https://linuxiac.com/high-priority-putty-vulnerability-found/ Cheers, Peter -- My Open Source Blog - http://open.fracpete.org

Packages With “t64” On The Ends Of Their Names
by Lawrence D'Oliveiro 15 Apr '24

15 Apr '24

Lately, in Debian Unstable, I have noticed package names starting to appear with “t64” on the ends. No doubt this will percolate through to Debian derivatives as well. I wondered what this was about, and found this forum thread <https://www.antixforum.com/forums/topic/t64-at-the-end-of-a-package-title/>. This has to do with the “year-2038” problem, which should only affect 32-bit systems anyway. But it seems some people are sufficiently concerned about this to ensure that their code will build with a 64-bit size for time_t (the POSIX type for holding the number of seconds since 1st January 1970), even on 32-bit systems. This is controlled at build time by setting the _TIME_BITS symbol to the value 64. There is a file /usr/include/features-time64.h (present if you have the libc6-dev package installed) that does the necessary setup of other time-related API calls based on this. On 64-bit systems (which is what most of us would be running by now), there would be absolutely no difference in the code with this setting. So the change in package name is I think only to maintain compatibility with 32-bit architectures.

“Highly capable” hackers root corporate networks by exploiting firewall 0-day
by Peter Reutemann 15 Apr '24

15 Apr '24

'Highly capable hackers are rooting multiple corporate networks by exploiting a maximum-severity zero-day vulnerability in a firewall product from Palo Alto Networks, researchers said Friday. The vulnerability, which has been under active exploitation for at least two weeks now, allows the hackers with no authentication to execute malicious code with root privileges, the highest possible level of system access, researchers said. The extent of the compromise, along with the ease of exploitation, has earned the CVE-2024-3400 vulnerability the maximum severity rating of 10.0. The ongoing attacks are the latest in a rash of attacks aimed at firewalls, VPNs, and file-transfer appliances, which are popular targets because of their wealth of vulnerabilities and direct pipeline into the most sensitive parts of a network.' -- source: https://arstechnica.com/security/2024/04/highly-capable-hackers-root-corpor… Cheers, Peter

New Spectre V2 Attack Impacts Linux Systems On Intel CPUs
by Peter Reutemann 14 Apr '24

14 Apr '24

'BleepingComputer reports: Researchers have demonstrated the "first native Spectre v2 exploit" for a new speculative execution side-channel flaw that impacts Linux systems running on many modern Intel processors. Spectre V2 is a new variant of the original Spectre attack discovered by a team of researchers at the VUSec group from VU Amsterdam. The researchers also released a tool that uses symbolic execution to identify exploitable code segments within the Linux kernel to help with mitigation. The new finding underscores the challenges in balancing performance optimization with security, which makes addressing fundamental CPU flaws complicated even six years after the discovery of the original Spectre.... As the CERT Coordination Center (CERT/CC) disclosed yesterday, the new flaw, tracked as CVE-2024-2201, allows unauthenticated attackers to read arbitrary memory data by leveraging speculative execution, bypassing present security mechanisms designed to isolate privilege levels. "An unauthenticated attacker can exploit this vulnerability to leak privileged memory from the CPU by speculatively jumping to a chosen gadget," reads the CERT/CC announcement. "Current research shows that existing mitigation techniques of disabling privileged eBPF and enabling (Fine)IBT are insufficient in stopping BHI exploitation against the kernel/hypervisor."

In a First, AlmaLinux Patches a Security Hole That Remains Unpatched in Upstream RHEL
by Peter Reutemann 10 Apr '24

10 Apr '24

'AlmaLinux, a three year old Linux distribution that started life as a clone of Red Hat Enterprise Linux, on Tuesday announced that it had created a patch to fix CVE-2024-1086, a security vulnerability that Red Hat evidently doesn’t think is important enough to patch in RHEL right away. “Though this was flagged as something to be fixed in Red Hat Enterprise Linux, Red Hat has only rated this as a moderate impact,” benny Vasquez, chairperson at the AlmaLinux Foundation explained in an article on the distro’s website on Tuesday. “Our users have asked us to patch this more quickly, and as such, we have opted to include patches ourselves. We released this kernel patch to the testing repo last weekend and plan to push it to production on Wednesday, April 3rd.” Since Vasquez’s post a production ready version of the fix was made available through the distro’s repositories, and Red Hat has re-evaluated the threat from its end and raised the severity level from “moderate” to “important.” There is still no sign of a patch from Red Hat, however, although the company has posted several methods for mitigating the threat. “This flaw is trivially exploitable on most RHEL-equivalent systems,” Vasquez said. “There are many proof-of-concept posts available now, including one from our Infrastructure team lead, Jonathan Wright (Dealing with CVE-2024-1086). In multi-user scenarios, this flaw is especially problematic.”' -- source: https://fossforce.com/2024/04/in-a-first-almalinux-patches-a-security-hole-… Cheers, Peter

EndeavourOS Bids Farewell to ARM Branch
by Peter Reutemann 10 Apr '24

10 Apr '24

'In a heartfelt announcement today, Bryan Poerwo, founder and project leader of EndeavourOS, marked the end of its ARM product branch. This project has been part of the EndeavourOS journey since its inception from the remnants of Antergos in 2019. The initiative, which began with the help of a passionate community member known as Pudge, later a leading figure of the EndeavourOS ARM team, aimed to extend the reach of EndeavourOS to ARM devices such as the ODROID N2, ODROID XU4, and Raspberry Pi 4. Over nearly five years, EndeavourOS ARM flourished, witnessing additions like support for the PineBook Pro and Raspberry Pi 5 and implementing a Calamares install option alongside the original scripts. However, the journey was challenging. The rapid advancement of Linux and desktop environments on x86_64 devices contrasted sharply with the slower pace of development in the ARM landscape, presenting a series of obstacles that tested the resolve of the project’s pioneers. The widening gap between ARM and x86_64 architectures, reduced external support, and personal transitions in hardware preferences led to a heartfelt decision to conclude the EndeavourOS ARM project. But not all is lost. As the project ends, the community remains hopeful, inviting anyone willing to carry the torch forward. The project’s GitHub repository continues to be available, serving as a foundation for future endeavors in the ARM Linux space.' -- source: https://linuxiac.com/endeavouros-bids-farewell-to-arm-branch/ Cheers, Peter

TrueNAS Moving From FreeBSD To Debian
by Lawrence D'Oliveiro 09 Apr '24

09 Apr '24

TrueNAS, makers of a turnkey system installation designed for NAS servers, announced close to a month ago that they were changing the emphasis in their product development from “TrueNAS CORE” (which is FreeBSD-based) to “TrueNAS SCALE” (which is Linux-based, specifically Debian-based) <https://www.theregister.com/2024/03/18/truenas_abandons_freebsd/>. This article <https://blocksandfiles.com/2024/04/08/ixsystems-no-one-is-getting-marooned/> gives some more background on the move: Kris Moore, SVP for engineering, told us: “Upstream has shifted. So first of all, ZFS, that’s kind of the heart and soul of TrueNAS and was for FreeNAS as well. Most of that [development] work takes place on Linux these days; features testing, all that happens on Linux. FreeBSD is the thing you port to and you’re done. So that momentum has moved.” ... “We had a huge chunk of our engineering staff spending time improving FreeBSD as opposed to working on features and functionalities. What’s happened now with the transition to having a Debian basis, the people I used to have 90 percent of their time working on FreeBSD, they’re working on ZFS features now … That’s what I want to see; value add for everybody versus sitting around, implementing something Linux had a years ago.” The irony in that is, ZFS was deliberately released by Sun (now Oracle) under a licence that is designed to be incompatible with the GPL that covers the Linux kernel. If you want to argue otherwise, consider that Oracle still refuses to include ZFS with its own Linux distro, preferring to offer you btrfs instead. Of course, you could also view that as a sign of a lack of confidence in its own home-grown filesystem ...

Tip For Repairing Ancient Linux Installations
by Lawrence D'Oliveiro 02 Apr '24

02 Apr '24

Here’s the scenario: there is a malfunctioning server running a really ancient Linux installation (e.g. 2.6.x-series kernel). You boot up with a reasonably recent copy of SystemRescue, mount the machine’s filesystem, try to chroot into it and run a shell ... and it segfaults. Seems there has been a subtle incompatible change in Linux kernel behaviour since those times, to do with the disabling of something called the “vsyscall” mechanism (which is specific to 64-bit x86-based machines, I understand). This was supposed to be a way to speed up certain commonly-executed system calls (I think getting the system time was one of them) by allowing direct transfers to certain entry points with fixed memory addresses for invoking them. It was later decided this was a bad idea (I think for security reasons). The mechanism has not been completely removed (yet), but nowadays it is disabled by default. To get around this, you need to boot SystemRescue with a change to the kernel command-line parameters, adding this item vsyscall=emulate After you get to a shell, you can confirm that this setting is in effect by checking the /proc/self/maps file (the memory mappings for your own process). At the bottom, there should be an entry with “[vdso]” in it, and below that another line with “[vsyscall]”. The presence of the latter line indicates that vsyscall emulation is in effect. This is not present when I check a process on my own machine, for example. Linus is legendary for being a stickler for never, ever breaking backward compatibility for userland. So the reasons for turning this off must have been pretty compelling, for him to agree to it. But the compromise is, it’s still there to be enabled if you really, really need it. There’s a bit more technical info here <https://0xax.gitbooks.io/linux-insides/content/SysCall/linux-syscall-3.html>, if you are interested. By the way, the above page is part of a book beginning here <https://0xax.gitbooks.io/linux-insides/content/>, about the insides of the Linux kernel. The whole book seems to be accessible from that link, but if you step up a level, the site doesn’t seem to have any idea about the existence of that book.

Uncle Sam’s Had It Up To Here With “Unforgivable” SQL Injection Flaws
by Lawrence D'Oliveiro 27 Mar '24

27 Mar '24

We all know SQL injection attacks are an ongoing problem <https://www.theregister.com/2024/03/26/fbi_cisa_sql_injection/>. What interested me about this article is this part: Software vendors have been advised to use parameterized queries with prepared statements to mitigate SQL injection vulnerabilities. According to the authorities, these allow user-input data to be separated from SQL queries and "better embody a secure by design approach" compared to input sanitization techniques. These are deployed by some vendors, but were branded "brittle" by CISA and the FBI. They said they're also difficult to deploy on a large scale and are more easily bypassed. Funny, that. Every time I post examples of how I dynamically construct SQL query strings with proper quoting of user input, I get yelled at and told to use “parameterized queries” and “prepared statements”, or even an ORM. Yet here we have the security experts saying that that is not a good solution, just like I thought all along.

Mozilla’s privacy service drops a provider with ties to people-search sites
by Peter Reutemann 26 Mar '24

26 Mar '24

'Mozilla's Monitor Plus, a service launched by the privacy-minded tech firm in February, notes on its pitch page that there is "a $240 billion industry of data brokers selling your private information for profit" and that its offering can "take back your privacy." Mozilla's most recent move to protect privacy has been to cut out one of the key providers of Monitor Plus' people-search protections, Onerep. That comes after reporting from security reporter Brian Krebs, who uncovered Onerep CEO and founder Dimitri Shelest as the founder of "dozens of people-search services since 2010," including one, Nuwber, that still sells the very kind of "background reports" that Monitor Plus seeks to curb. Shelest told Krebs in a statement (PDF) that he did have an ownership stake in Nuwber, but that Nuwber has "zero cross-over or information-sharing with Onerep" and that he no longer operates any other people-search sites. Shelest admitted the bad look but said that his experience with people search gave Onerep "the best tech and team in the space." Brandon Borrman, vice president of communications at Mozilla, said in a statement that while "customer data was never at risk, the outside financial interests and activities of Onerep’s CEO do not align with our values." Mozilla is "working now to solidify a transition plan," Borrman said. A Mozilla spokesperson confirmed to Ars today that Mozilla is continuing to offer Monitor Plus, suggesting no pause in subscriptions, at least for the moment.' -- source: https://arstechnica.com/gadgets/2024/03/mozillas-privacy-service-drops-a-pr… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hi everyone I've long had a problem with being unable to open some PDFs that could be either viewed on Windows or on Google Drive. For some reason, some PDFs appear to be encrypted (but not requiring a password??).

Database-Based Operating System 'DBOS' Does Things Linux Can't
by Peter Reutemann 19 Mar '24

19 Mar '24

'Databricks CTO Matei Zaharia "said that Databricks had to keep track of scheduling a million things," remembers adjunct MIT professor Michael Stonebraker. " He said that this can't be done with traditional operating system scheduling, and so this was done out of a Postgres database. And then he started to whine that Postgres was too slow, and I told him we can do better than that...." This resulted in DBOS — short for "database operating system" — which they teamed up to build with teams Stanford and MIT, according to The Next Platform: They founded a company to commercialize the idea in April 2023 and secured $8.5 million initial seed funding to start building the real DBOS. Engine Ventures and Construct Capital led the funding, along with Sinewave and GutBrain Ventures... "The state that the operating system has to keep track of — memory, files, messages, and so on — is approximately linear to the resources you have got," says Stonebraker. "So without me saying another word, keeping track of operating system state is a database problem not addressed by current operating system schedulers. Moreover, OLTP [Online Transaction Processing] database performance has gone up dramatically, and that is why we thought instead of running the database system in user space on top of the operating system, why don't we invert our thinking 180 degrees and run the operating system on top of the database, with all of the operating services are coded in SQL...?" For now, DBOS can give the same kind of performance as that full blown Linux operating system, and thanks to the distributed database underpinnings of its kernel, it can do things that a Linux kernel just cannot do... One is provide reliable execution, which means that if a program running atop DBOS is ever interrupted, it starts where it left off and does not have to redo its work from some arbitrary earlier point and does not crash and have to start from the beginning. And because every little bit of the state of the operating system — and therefore the applications that run atop it — is preserved, you can go backwards in time in the system and restart the operating system if it experiences some sort of anomaly, such as a bad piece of application software running or a hack attack. You can use this "time travel" feature, as Stonebraker calls it, to reproduce what are called heisenbugs — ones that are very hard to reproduce precisely because there is no shared state in the distributed Linux and Kubernetes environment and that are increasingly prevalent in a world of microservices. The other benefit of the DBOS is that it presents a smaller attack surface for hackers, which boosts security, and that you analyze the metrics of the operating system in place since they are already in a NoSQL database that can be queried rather than aggregating a bunch of log files from up and down the software stack to try to figure out what is going on... There is also a custom tier for DBOS, which we presume costs money, that can use other databases and datastores for user application data, stores more than three days of log data, can have multiple users per account, that adds email and Slack support with DBOS techies, and that is available on other clouds as well as AWS. The operating system kernel/scheduler "is itself largely a database," with services written in TypeScript, according to the article. The first iteration used the FoundationDB distributed key-value store for its scheduling core (open sourced by Apple in 2018), according to the article — "a blazingly fast NoSQL database... Stonebraker says there is no reason to believe that DBOS can't scale across 1 million cores or more and support Java, Python, and other application languages as they are needed by customers..." And the article speculates they could take things even further. "There is no reason why DBOS cannot complete the circle and not only have a database as an operating system kernel, but also have a relational database as the file system for applications."' -- source: https://developers.slashdot.org/story/24/03/18/0038232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Ends its Privacy-Friendly GPS-Style Location Service
by Peter Reutemann 18 Mar '24

18 Mar '24

'Mozilla Location Service offered "a free, open way to offer GPS-style location detection features" for developers on devices without GPS hardware, remembers the Linux blog OMG Ubuntu. It used signals like Wi-Fi access points and Bluetooth beacons "without any of the privacy implications most competing geolocation services have." But Friday they reported that Mozilla "has announced it is ending access to Mozilla Location Service (MLS), which provides accurate, privacy-respecting, and crowdsourced geolocation data." Developers and 3rd-party projects that use MLS to detect a users' location, such as the freedesktop.org location framework GeoClue, which is used by apps like GNOME Maps and Weather, have only a few months left to continue using the service... In late March, POST data submissions will return 403 responses. Finally, on June 12, all 3rd-party API keys will be removed and MLS data only accessible by Mozilla... MLS' accuracy has declined in recent years. Patent infringement claims in 2019 saw Mozilla reach a settlement to avoid litigation. As part of that settlement it was forced to make changes to MLS that impacted its ability to invest in (commercially exploit?) and improve the service. The article notes that GeoClue "already supports multiple location detection methods, including IP-based ones," so it should continue operating. "But the sad reality is that there just aren't a lot of free, open, privacy-friendly, accurate, and (rather importantly for a framework built in to Linux desktops) reliable alternatives to Mozilla Location Services, which has built up a colossal 'signal map' from which to pinpoint locations." "We are grateful for the contributions of the community to MLS to both the code and the dataset," a Mozilla senior engineering manager said in a statement.' -- source: https://tech.slashdot.org/story/24/03/17/2150221/mozilla-ends-its-privacy-f… I wasn't even aware that Mozilla was offering such a service...

by Lawrence D'Oliveiro 18 Mar '24

18 Mar '24

One of the recent additions to the Bitsavers vintage computing collection is this presentation from 1986 <http://bitsavers.trailing-edge.com/pdf/ibm/share/SHARE67_Presentation_on_Se…> at a session of SHARE (one of the IBM user groups), on how to ensure your computer’s time is set correctly. Remember, this was before NTP. But there was already a worldwide network of atomic clocks, keeping synchronization with each other, and there were shortwave stations, like WWV in Boulder, Colorado, that would broadcast pips once per second, synchronized to the atomic clock network. And there were even consumer-level gadgets, like the one mentioned in the article from Heath, that would automatically decode those broadcasts and output a time code a computer could read. The article has some nice background info. Like did you know there can be up to a 1-second discrepancy between GMT and UTC? (Actually I think from other sources the limit might be more like 0.9 seconds.) IBM’s mainframe OS developers were perceptive enough to realize that it can be useful to have the computer keep time in GMT, and maintain an offset for calculating local time. Particular site admins could of course have the choice of using local time for the system time, and setting the offset to zero. Changing the offset for daylight saving could be a fraught procedure, though. The level of confusion it could cause for running applications was such that it was safer to do a reboot. One little item I don’t recall coming across before, another of those NASA programming screwups: One of the famous programming mistakes of all time was by the programmer who thought the earth revolved on its axis once every 24 hours and used that fact to calculate landing sites for the Mercury space flights. Our first astronauts spent a lot more time in the water than they should have because of that.

Free/Libre 'GnuCOBOL' Compiler Reaches Maturity, Can Compete with Proprietary Offerings
by Peter Reutemann 18 Mar '24

18 Mar '24

'After 20 years of development, the open source GnuCOBOL "has reached an industrial maturity and can compete with proprietary offers in all environments," said OCamlPro founder and GnuCOBOL contributor Fabrice Le Fessant, in a FOSDEM talk about the technology. GnuCOBOL turns COBOL source code into executable applications. It is very cross-platform, running Linux, BSD, many proprietary Unixes, macOS, and Windows, even Android. And the latest version, v.32, is being used in many commercial settings... Sobisch noted that the GnuCOBOL is seeing a lot of commercial deployments, such as for banking back-end apps, many of which are being migrated from Micro Focus, with users reporting performance improvements as a result. The French DGFIP federal agency moved from a GCOS mainframe to GnuCOBOL, with the help of Le Fessant's firm. Originally called OpenCOBOL, the project was started in 2002 and renamed GnuCOBOL in 2013. In the past three years, it has received attention from 13 contributors with 460 commits. Most Linux package managers have a copy of GnuCOBOL for the program for downloading... It can compile to C code (C89+), making it extremely portable, from mainframes to Raspberry Pi's, Sobisch said... Also new is SuperBOL, a development studio for GnuCOBOL developed by Le Fessant's OCamlPro. It runs as a VSCode Extension and features a full COBOL processor (written in OCaml).

Never-before-seen Linux malware gets installed using 1-day exploits
by Peter Reutemann 12 Mar '24

12 Mar '24

'Researchers have unearthed Linux malware that circulated in the wild for at least two years before being identified as a credential stealer that’s installed by the exploitation of recently patched vulnerabilities. The newly identified malware is a Linux variant of NerbianRAT, a remote access Trojan first described in 2022 by researchers at security firm Proofpoint. Last Friday, Checkpoint Research revealed that the Linux version has existed since at least the same year, when it was uploaded to the VirusTotal malware identification site. Checkpoint went on to conclude that Magnet Goblin—the name the security firm uses to track the financially motivated threat actor using the malware—has installed it by exploiting “1-days,” which are recently patched vulnerabilities. Attackers in this scenario reverse engineer security updates, or copy associated proof-of-concept exploits, for use against devices that have yet to install the patches. Checkpoint also identified MiniNerbian, a smaller version of NerbianRAT for Linux that’s used to backdoor servers running the Magento ecommerce server, primarily for use as command and control servers that devices infected by NerbianRAT connect to. Researchers elsewhere have reported encountering servers that appear to have been compromised with MiniNerbian, but Checkpoint Research appears to have been the first to identify the underlying binary.' -- source: https://arstechnica.com/security/2024/03/never-before-seen-linux-malware-ge… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux 6.9 Will Be the First To Top 10 Million Git Objects
by Peter Reutemann 12 Mar '24

12 Mar '24

'Linus Torvalds has released version 6.8 of the Linux Kernel. "So it took a bit longer for the commit counts to come down this release than I tend to prefer," Torvalds wrote on the Linx kernel mailing list on Sunday, "but a lot of that seemed to be about various selftest updates (networking in particular) rather than any actual real sign of problems." "And the last two weeks have been pretty quiet, so I feel there's no real reason to delay 6.8." So he delivered it, ending his own speculation that this cut of the kernel might need an eighth release candidate. Torvalds found time to note what he described as "a bit of random git numerology" as when work ended on this version of the kernel the git repository used to track it contained 9.996 million objects." "This is the last mainline kernel to have less than ten million git objects," Torvalds wrote. "Of course, there is absolutely nothing special about it apart from a nice round number. Git doesn't care," he added. Fair enough -- especially as noted that other trees, such as linux-next, have well and truly passed ten million objects.' -- source: https://linux.slashdot.org/story/24/03/11/1620223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Do Scientists Take Backups?
by Lawrence D'Oliveiro 11 Mar '24

11 Mar '24

Martin Eve, who works at Crossref, which manages the DOI system which tries to offer permanent online links to scientific publications and other digital documents, decided to do a survey of those links, to see how many of them would still actually resolve. The results were less than reassuring <https://arstechnica.com/science/2024/03/study-finds-that-we-could-lose-scie…>. If/when a publisher goes bankrupt, what happens to their online archives? Do researchers who submit papers keep backup copies of their papers?

“We Had To Educate Oracle About Our Contract”
by Lawrence D'Oliveiro 08 Mar '24

08 Mar '24

Slightly chilling words to hear, don’t you think? Corporations that do volume deals with proprietary suppliers like Oracle and SAP have to agree to allow periodic audits by the vendor to ensure they are complying with the licence terms. Vendors have been known to try to pull a fast one during these audits. This customer <https://www.theregister.com/2024/03/06/oracle_audits/> mentions that Oracle, in particular, had a tendency to assume the software was licensed under their current terms, when in fact the contract was agreed under quite different, older terms. Hence the need to keep “educating” (i.e. reminding) the vendor about what the correct criteria were.

Fedora Workstation 41 To No Longer Install GNOME X.Org Session By Default
by Peter Reutemann 08 Mar '24

08 Mar '24

'Michael Larabel writes via Phoronix: Fedora Workstation has long defaulted to using GNOME's Wayland session by default, but it has continued to install the GNOME X.Org session for fallback purposes or those opting to use it instead. But for the Fedora Workstation 41 release later in the year, there is a newly-approved plan to no longer have that GNOME X.Org session installed by default. Recently there was a Fedora Workstation ticket opened to no longer install the GNOME X.Org session by default. This is just about whether the X.Org session is pre-installed but would continue to live in the repository for those wanting to explicitly install it. The Fedora Workstation working group decided to go ahead with this change for the Fedora 41 cycle, not the upcoming Fedora 40 release. So pending any obstacles by FESCo, which is unlikely. Fedora Workstation 41 will not be installing the GNOME X.Org session by default. Long live Wayland.' -- source: https://news.slashdot.org/story/24/03/07/2157258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How to Run Android Applications on Ubuntu with Waydroid
by Peter Reutemann 06 Mar '24

French Court Issues Damages Award For Violation of GPL
by Peter Reutemann 04 Mar '24

04 Mar '24

'Some news from "Copyleft Currents", the blog of open-source/IP lawyer Heather Meeker: On February 14, 2024, the Court of Appeal of Paris issued an order stating that Orange, a major French telecom provider, had infringed the copyight of Entr'Ouvert's Lasso software and violated the GPL. They ordered Orange to pay €500,000 in compensatory damages and €150,000 for moral damages. This case has been ongoing for many years. Entr'ouvert is the publisher of Lasso, a reference library for the Security Assertion Markup Language (SAML) protocol, an open standard for identity providers to authenticate users and pass authentication tokens to online services. This is the open protocol that enables single sign-on (SSO). The Lasso product is dual licensed by Entr'Ouvert under GPL or commercial licenses. In 2005, Orange won a contract with the French Agency for the Development of Electronic Administration to develop parts of the service-public.fr portal, which allows users to interact online with the government for administrative procedures. Orange used the Lasso software in the solution, but did not pass on the rights to its modifications free of charge under GPL, or make the source code to its modifications available. Entr'Ouvert sued Orange in 2010, and the case wended its way through the courts, turning on, among other things, issues of proof of Entr'Ouvert 's copyright interest in the software, and whether the case properly sounded in breach of contract or copyright infringement... The compensatory damages were based on both lost profits of the plaintiff and disgorgement of profits of Orange. Moral damages compensate the plaintiff for harm to reputation or other non-monetary injury.' -- source: https://news.slashdot.org/story/24/03/03/030200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Rentware Comes To Hardware

You already have companies like Adobe and Autodesk making their software subscription-only, so you have to keep paying to use it; now HP is bringing the same idea to its printers <https://arstechnica.com/gadgets/2024/02/hp-wants-you-to-pay-up-to-36-month-…>. You pay a monthly fee (inclusive of ink as well as printer rental), and you get to print a certain number of pages each month. This will require an always-on Internet connection, so HP can monitor your printer. This will allow them to collect information, not just on ink levels, but on what kind of printing you are doing, even the applications you are using. How would you like to “never own a printer again”? (Their tag line.) I suppose you should be grateful they aren’t requiring you to buy their paper as well. At least, not yet ...

'Paying People To Work on Open Source is Good Actually'
by Peter Reutemann 01 Mar '24

01 Mar '24

'Jacob Kaplan-Moss, one of the lead developers of Django, writes in a long post that he says has come from a place of frustration: [...] Instead, every time a maintainer finds a way to get paid, people show up to criticize and complain. Non-OSI licenses "don"t count" as open source. Someone employed by Microsoft is "beholden to corporate interests" and not to be trusted. Patreon is "asking for handouts." Raising money through GitHub sponsors is "supporting Microsoft's rent-seeking." VC funding means we're being set up for a "rug pull" or "enshitification." Open Core is "bait and switch." None of this is hypothetical; each of these examples are actual things I've seen said about maintainers who take money for their work. One maintainer even told me he got criticized for selling t-shirts! Look. There are absolutely problems with every tactic we have to support maintainers. It's true that VC investment comes with strings attached that often lead to problems down the line. It sucks that Patreon or GitHub (and Stripe) take a cut of sponsor money. The additional restrictions imposed by PolyForm or the BSL really do go against the Freedom 0 ideal. I myself am often frustrated by discovering that some key feature I want out of an open core tool is only available to paid licensees. But you can criticize these systems while still supporting and celebrating the maintainers! Yell at A16Z all you like, I don't care. (Neither do they.) But yelling at a maintainer because they took money from a VC is directing that anger in the wrong direction. The structural and societal problems that make all these different funding models problematic aren't the fault of the people trying to make a living doing open source. It's like yelling at someone for shopping at Dollar General when it's the only store they have access to. Dollar General's predatory business model absolutely sucks, as do the governmental policies that lead to food deserts, but none of that is on the shoulders of the person who needs milk and doesn't have alternatives.' -- source: https://news.slashdot.org/story/24/02/29/0746221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

HDMI Forum Rejects Open-Source HDMI 2.1 Driver Support Sought By AMD
by Peter Reutemann 01 Mar '24

01 Mar '24

'Michael Larabel, reporting at Phoronix: One of the limitations of AMD's open-source Linux graphics driver has been the inability to implement HDMI 2.1+ functionality on the basis of legal requirements by the HDMI Forum. AMD engineers had been working to come up with a solution in conjunction with the HDMI Forum for being able to provide HDMI 2.1+ capabilities with their open-source Linux kernel driver, but it looks like those efforts for now have concluded and failed. For three years there has been a bug report around 4K(a)120Hz being unavailable via HDMI 2.1 on the AMD Linux driver. Similarly, there have been bug reports like 5K @ 240Hz not possible either with the AMD graphics driver on Linux. As covered back in 2021, the HDMI Forum closing public specification access is hurting open-source support. AMD as well as the X.Org Foundation have been engaged with the HDMI Forum to try to come up with a solution to be able to provide open-source implementations of the now-private HDMI specs. AMD Linux engineers have spent months working with their legal team and evaluating all HDMI features to determine if/how they can be exposed in their open-source driver. AMD had code working internally and then the past few months were waiting on approval from the HDMI Forum. Sadly, the HDMI Forum has turned down AMD's request for open-source driver support.' -- source: https://it.slashdot.org/story/24/02/29/076217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GitHub besieged by millions of malicious repositories in ongoing attack

'GitHub is struggling to contain an ongoing attack that’s flooding the site with millions of code repositories. These repositories contain obfuscated malware that steals passwords and cryptocurrency from developer devices, researchers said. The malicious repositories are clones of legitimate ones, making them hard to distinguish to the casual eye. An unknown party has automated a process that forks legitimate repositories, meaning the source code is copied so developers can use it in an independent project that builds on the original one. The result is millions of forks with names identical to the original one that add a payload that’s wrapped under seven layers of obfuscation. To make matters worse, some people, unaware of the malice of these imitators, are forking the forks, which adds to the flood.' -- source: https://arstechnica.com/security/2024/02/github-besieged-by-millions-of-mal… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Tumblr and Wordpress Are Preparing To Sell User Data To OpenAI and Midjourney, Report Says

US Government Demands Memory-Safe Programming Languages
by Lawrence D'Oliveiro 28 Feb '24

28 Feb '24

The US Office of the National Cyber Director has put out a report on “a path towards secure and measurable software” <https://devclass.com/2024/02/27/white-house-demands-memory-safe-programming…>. It talks a lot about memory safety, including hardware techniques such as the old “capabilities” idea being resurrected in the CHERI project. And the Rust Foundation has chimed in with some comments about use of their language which is specifically designed to enforce memory safety. But a group of C++ fans has counterclaimed that memory safety is only “a very small part of security”, and that “C++ benefits from having a formal specification, a fully-specified memory model, and an active community of users and implementers”, and that education can improve the quality of code written in C and C++. It also tries to imply that Rust is somehow less desirable because it lacks a formal specification.

Is Windows 64-Bit Yet?
by Lawrence D'Oliveiro 27 Feb '24

27 Feb '24

Given that 64-bit Windows has been shipping for so long, you would think most Windows software, particularly Microsoft’s own software, would have made the transition from 32-bit long ago. After all, on a typical 64-bit Linux system, everything is 64-bit, and has been that way since the early days. So I was mildly surprised to discover that Visual Studio only became 64-bit in November 2021. And today I am even more surprised to discover that the change broke its own Windows Forms framework, and a fix is still not available to this day <https://devclass.com/2024/02/26/microsoft-struggles-to-address-fallout-from…>.

The State Of IoT
by Lawrence D'Oliveiro 23 Feb '24

23 Feb '24

This backflip from Microsoft <https://www.theregister.com/2024/02/21/microsoft_azure_iot_central/> retracting an earlier announcement that seemingly undermined a major part of its “Internet-of-Things” efforts seems to do little to clear the confusion. I found this part of the report quite revealing: The insider also pointed out that vendors struggle to produce value for organizations developing and deploying IoT applications. While the industry underestimated the scale of the challenge in connecting thousands of sensors, each of which could generate 86,400 values per day, it also failed to form a commercial model that worked for everyone. Vendors were focused only on owning the platform and were reluctant to build applications on anyone else's, creating a stalemate, the insider said. Meanwhile, the “maker” movement continues on its merry way, building its applications and toolkits on (and for) open-source platforms like the Raspberry Pi and Arduino, while completely failing to spend billions of dollars on proprietary products. And the proprietary companies can do nothing but search desperately for some lever that will give them that valuable vendor lock-in, but all they can achieve is wrestle each other to a stalemate. Me, I consider that a win-win situation. ;)

'From a blog post by Greg Kroah-Hartman: As was recently announced, the Linux kernel project has been accepted as a CVE Numbering Authority (CNA) for vulnerabilities found in Linux. This is a trend, of more open source projects taking over the haphazard assignments of CVEs against their project by becoming a CNA so that no other group can assign CVEs without their involvment. Here's the curl project doing much the same thing for the same reasons. I'd like to point out the great work that the Python project has done in supporting this effort, and the OpenSSF project also encouraging it and providing documentation and help for open source projects to accomplish this. I'd also like to thank the cve.org group and board as they all made the application process very smooth for us and provided loads of help in making this all possible. As many of you all know, I have talked a lot about CVEs in the past, and yes, I think the system overall is broken in many ways, but this change is a way for us to take more responsibility for this, and hopefully make the process better over time. It's also work that it looks like all open source projects might be mandated to do with the recent rules and laws being enacted in different parts of the world, so having this in place with the kernel will allow us to notify all sorts of different CNA-like organizations if needed in the future. Kroah-Hartman links to his post on the kernel mailing list for "more details about how this is all going to work for the kernel." [D]ue to the layer at which the Linux kernel is in a system, almost any bug might be exploitable to compromise the security of the kernel, but the possibility of exploitation is often not evident when the bug is fixed. Because of this, the CVE assignment team are overly cautious and assign CVE numbers to any bugfix that they identify. This explains the seemingly large number of CVEs that are issued by the Linux kernel team... No CVEs will be assigned for unfixed security issues in the Linux kernel, assignment will only happen after a fix is available as it can be properly tracked that way by the git commit id of the original fix. No CVEs will be assigned for any issue found in a version of the kernel that is not currently being actively supported by the Stable/LTS kernel team. alanw (Slashdot reader #1,822) worries this could overwhelm the CVE infrastructure, pointing to an ongoing discussion at LWN.net. But reached for a comment, Greg Kroah-Hartman thinks there's been a misunderstanding. He told Slashdot that the CVE group "explicitly asked for this as part of our application... so if they are comfortable with it, why is no one else?"' -- source: https://linux.slashdot.org/story/24/02/17/1811258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Nginx core developer quits project in security dispute, starts “freenginx” fork
by Peter Reutemann 16 Feb '24

16 Feb '24

'A core developer of Nginx, currently the world's most popular web server, has quit the project, stating that he no longer sees it as "a free and open source project… for the public good." His fork, freenginx, is "going to be run by developers, and not corporate entities," writes Maxim Dounin, and will be "free from arbitrary corporate actions." Dounin is one of the earliest and still most active coders on the open source Nginx project and one of the first employees of Nginx, Inc., a company created in 2011 to commercially support the steadily growing web server. Nginx is now used on roughly one-third of the world's web servers, ahead of Apache. Nginx Inc. was acquired by Seattle-based networking firm F5 in 2019. Later that year, two of Nginx's leaders, Maxim Konovalov and Igor Sysoev, were detained and interrogated in their homes by armed Russian state agents. Sysoev's former employer, Internet firm Rambler, claimed that it owned the rights to Nginx's source code, as it was developed during Sysoev's tenure at Rambler (where Dounin also worked). While the criminal charges and rights do not appear to have materialized, the implications of a Russian company's intrusion into a popular open source piece of the web's infrastructure caused some alarm. Sysoev left F5 and the Nginx project in early 2022. Later that year, due to the Russian invasion of Ukraine, F5 discontinued all operations in Russia. Some Nginx developers still in Russia formed Angie, developed in large part to support Nginx users in Russia. Dounin technically stopped working for F5 at that point, too, but maintained his role in Nginx "as a volunteer," according to Dounin's mailing list post. Dounin writes in his announcement that "new non-technical management" at F5 "recently decided that they know better how to run open source projects. In particular, they decided to interfere with security policy nginx uses for years, ignoring both the policy and developers' position." While it was "quite understandable," given their ownership, Dounin wrote that it means he was "no longer able to control which changes are made in nginx," hence his departure and fork.' -- source: https://arstechnica.com/information-technology/2024/02/nginx-key-developer-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Asahi Linux Project's OpenGL Support On Apple Silicon Officially Surpasses Apple's
by Peter Reutemann 16 Feb '24

16 Feb '24

'Andrew Cunningham reports via Ars Technica: For around three years now, the team of independent developers behind the Asahi Linux project has worked to support Linux on Apple Silicon Macs, despite Apple's total lack of involvement. Over the years, the project has gone from a "highly unstable experiment" to a "surprisingly functional and usable desktop operating system." Even Linus Torvalds has used it to run Linux on Apple's hardware. The team has been steadily improving its open source, standards-conformant GPU driver for the M1 and M2 since releasing them in December 2022, and today, the team crossed an important symbolic milestone: The Asahi driver's support for the OpenGL and OpenGL ES graphics have officially passed what Apple offers in macOS. The team's latest graphics driver fully conforms with OpenGL version 4.6 and OpenGL ES version 3.2, the most recent version of either API. Apple's support in macOS tops out at OpenGL 4.1, announced in July 2010. Developer Alyssa Rosenzweig wrote a detailed blog post that announced the new driver, which had to pass "over 100,000 tests" to be deemed officially conformant. The team achieved this milestone despite the fact that Apple's GPUs don't support some features that would have made implementing these APIs more straightforward. "Regrettably, the M1 doesn't map well to any graphics standard newer than OpenGL ES 3.1," writes Rosenzweig. "While Vulkan makes some of these features optional, the missing features are required to layer DirectX and OpenGL on top. No existing solution on M1 gets past the OpenGL 4.1 feature set... Without hardware support, new features need new tricks. Geometry shaders, tessellation, and transform feedback become compute shaders. Cull distance becomes a transformed interpolated value. Clip control becomes a vertex shader epilogue. The list goes on." Now that the Asahi GPU driver supports the latest OpenGL and OpenGL ES standards -- released in 2017 and 2015, respectively -- the work turns to supporting the low-overhead Vulkan API on Apple's hardware. Vulkan support in macOS is limited to translation layers like MoltenVK, which translates Vulkan API calls to Metal ones that the hardware and OS can understand. [...] Rosenzweig's blog post didn't give any specific updates on Vulkan except to say that the team was "well on the road" to supporting it. In addition to supporting native Linux apps, supporting more graphics APIs in Asahi will allow the operating system to take better advantage of software like Valve's Proton, which already has a few games written for x86-based Windows PCs running on Arm-based Apple hardware.

Firefox Maker Mozilla Is Cutting 60 Jobs After Naming New CEO

'Less than a week after naming Laura Chambers as interim CEO, Firefox's maker Mozilla said it is cutting about 60 jobs, or 5% of its workforce. The cuts are primarily in the product development organization. Bloomberg reports: "We're scaling back investment in some product areas in order to focus on areas that we feel have the greatest chance of success," Mozilla said in a statement. "We intend to re-prioritize resources against products like Firefox Mobile, where there's a significant opportunity to grow and establish a better model for the industry." Mozilla last cut a significant number of jobs four years ago at the height of the Covid-19 pandemic. The not-for-profit company, which competes with Alphabet Inc.'s Google Chrome, Apple Inc.'s Safari and Microsoft Corp.'s Edge, has been grappling with sliding market share of its Firefox web browser in recent years. So far in 2024, the tech sector has cut 32,000 jobs.

HPC Wiki
by Lawrence D'Oliveiro 14 Feb '24

Recently discovered this site <https://hpc-wiki.info/hpc/HPC_Wiki>, which gives some useful introductory info to those wanting to learn how to program a supercomputer (or just curious about the process). For example, here <https://hpc-wiki.info/hpc/MPI> is an intro to one parallelization architecture, called MPI, and here <https://hpc-wiki.info/hpc/OpenMP> is an intro to another one, called OpenMP. Note the examples are given in C and Fortran, and both rely heavily on preprocessors/compiler plugins in order to generate the right code. Yes, Fortran is still in heavy use, it seems. And if you learned your Fortran before the 1990s (as I did), you may not even recognize it as the same language.

'Damn Small Linux' is Back - But Bigger
by Peter Reutemann 13 Feb '24

13 Feb '24

'Back in 2006 Slashdot reported on a 50-megabyte "micro" distro called Damn Small Linux. (And in 2012 we wrote that it "rose from the dead" with a new release candidate.) Now Damn Small Linux has been reborn again, according to its developer's web site: Creating the original DSL, a versatile 50MB distribution, was a lot of fun and one of the things I am most proud of as a personal accomplishment. However, as a concept, it was in the right place at the right time, and the computer industry has changed a lot since then. While it would be possible to make a bootable Xwindows 50MB distribution today, it would be missing many drivers and have only a handful of very rudimentary applications. People would find such a distribution a fun toy or something to build upon, but it would not be usable for the average computer user out of the gate.... The new goal of DSL is to pack as much usable desktop distribution into an image small enough to fit on a single CD, or a hard limit of 700MB. This project is meant to service older computers and have them continue to be useful far into the future. Such a notion sits well with my values. I think of this project as my way of keeping otherwise usable hardware out of landfills. As with most things in the GNU/Linux community, this project continues to stand on the shoulders of giants. I am just one guy without a CS degree, so for now, this project is based on antiX 23 i386... a fantastic distribution that I think shares much of the same spirit as the original DSL project. AntiX shares pedigree with MEPIS and also leans heavily on the geniuses at Debian. The blog It's FOSS News describes it as "a unique experience in a sea of Debian-based and Fedora-based distros." It is offered with two window managers, Fluxbox and JWM, with apt being fully enabled by default for easy package installations... At the time of writing, only the Alpha ISOs were made available on the official downloads page. It is only a matter of time before we get a stable release.' -- source: https://linux.slashdot.org/story/24/02/11/2049252 I actually used DSL back in the day...
