Linux Developers Consider Retiring The x32 ABI

2 months ago
The Linux kernel mailing list has a new patch proposing the retirement of the x32 ABI, reports Phoronix: The Linux x32 ABI for x86_64 processors allow making use of the full 64-bit register file and wide data path but retaining 32-bit pointers to provide for a smaller memory footprint when not needing 64-bit pointers. Linux x32 came to the party late and didn't enjoy much adoption over the years and is now looking at possible removal from the Linux kernel. The x32 code was a nice concept for helping lower memory footprint requirements while otherwise making use of the x86_64 capabilities, but with its limited adoption and x86_64 simply being the de facto standard these days, Linux kernel developers are looking at phasing out the x32 ABI. The x32 ABI was added in Linux 3.4 back in 2012 plus also required updated compiler support too. The proposed patch argues "there is practically no real use for x32," noting that some Linux vendors (like Debian) already disable x32 by default to reduce attack surfaces. "Should nothing happen within the next half year, lets remove code bits around August after the summer break." Discussions about dropping x32 support first started in 2018...

'Call Of Duty: Warzone' Is Shutting Down On PS4 And Xbox One

2 months ago
Call Of Duty: Warzone is shutting down on PS4 and Xbox One later this year, reports Kotaku. As Call of Duty fully transitions to PS5 and Xbox Series X/S (and Switch 2), its popular battle royale spin-off, Warzone, is also ditching the old consoles. Later this year, Warzone will no longer be playable on PS4 or Xbox One... Shortly after Modern Warfare 4 ( MW4) launches on October 23, it will be integrated with Warzone. But because MW4 is skipping PS4 and Xbox One, Activision is starting the process of shutting down Warzone on those older consoles... "Beginning June 4, the game will no longer be available for new downloads on those platforms," [Activision wrote on their blog], "though existing players can continue playing until Season 1 launches. Certain items, such as Call of Duty Points bundle purchases, will no longer be available on those platforms...." Players who have properly linked their platform accounts to their Activision accounts will be able to keep all their progress and unlocks once they leap to PS5, Xbox Series X/S, or PC. Activision also confirmed on its support site that all past Call of Duty games will remain playable online on PS4 and Xbox One. The upcoming Call of Duty: Modern Warfare 4 "will be set against a full-scale invasion of South Korea," according to the Washington Post. And they report that Infinity Ward will release the game October 23 "on all modern gaming platforms including, notably, the Nintendo Switch 2. (The blockbuster franchise has long skipped Nintendo consoles.)" The campaign introduces Private Park, a young Korean soldier thrown into combat for the first time, framed as a classic "zero-to-hero story" against the backdrop of global calamity. The franchise's most recognizable hero, Capt. John Price, also returns, this time as a rogue agent, picking up the story of the Modern Warfare timeline that began with 2019's reboot title... [T]he game features a fictional North Korean leader, rather than Kim Jong Un or his family. Infinity Ward said it consulted regional specialists, people who defected from the North and the studio's own Korean employees. When asked whether the studio is braced for a diplomatic response from Pyongyang (familiar territory for the series), [Jack O'Hara, co-head of Infinity Ward] was dry about it. "We've had state responses to our games before. We'll find out what we all think about each other soon enough," he said... Infinity Ward is making its most significant mechanical changes in years. The game will remove "bloom," the randomized bullet spread visual trick that game developers use to simulate gunfire chaos, while firing guns from the hip. Instead, bullets will exit the gun in the same direction as the visible recoil on screen, rewarding aim over chance... The studio is also introducing Kill Block, a multiplayer map that reconfigures itself between matches using a modular system of interchangeable sections, producing more than 500 possible layouts.

Microsoft Criticized for Threatening Legal Action Against Security Researcher

2 months ago
"A security researcher published a series of unpatched bugs in Microsoft products," reports TechCrunch, "along with code to exploit them." Microsoft's response to the researcher? "Threatening to take legal action and call the cops on them." On Wednesday, Microsoft published a blog post criticizing the researcher, who goes by the handle "Nightmare Eclipse," for publicly disclosing a series of bugs, including BlueHammer, RedSun, UnDefend, and YellowKey. The flaws affected products such as the Windows built-in antivirus engine Defender and the disk-encryption tool BitLocker. The core of Microsoft's complaints is that the researcher did not attempt to report the bugs so that the company could fix them. That would have been "responsible," as Microsoft's blog put it. The other side of the company's argument is that by publishing the details of the bugs and how to exploit them before they were patched, Nightmare Eclipse may have aided malicious hackers. Some of the vulnerabilities Nightmare Eclipse disclosed have since been used by hackers in real-world attacks, according to Microsoft, as well as the U.S. cybersecurity agency CISA. "Our Digital Crimes Unit will continue bringing cases against these actors and those that enable their criminal activity — coordinating as needed with law enforcement around the world," Microsoft wrote... In a series of blog posts published in the last couple of weeks — without providing many specific details — Nightmare Eclipse claimed to have been in contact with Microsoft, but the company allegedly mistreated them, including revoking access to their Microsoft Security Response Center account, the portal where researchers can report vulnerabilities to the tech giant. Nightmare Eclipse's implication was that they had no choice but to release the vulnerabilities publicly... The researchers published the bugs on open source repositories GitHub (owned by Microsoft) and GitLab. The researchers' accounts on those platforms have been banned... In response to this latest controversy with Nightmare Eclipse, countless researchers have shared their bad experiences reporting bugs to Microsoft. Thanks to long-time Slashdot reader Elektroschock for sharing the news.
