[$] Shadow-stack control in clone3()

1 hét 6 nap óta
Shadow stacks are a control-flow-integrity feature designed to defend against exploits that manipulate a thread's call stack. The kernel first gained support for hardware-implemented shadow stacks, for the x86 architecture, in the 6.6 release; 64-bit Arm support followed in 6.13. This feature does not give user space much control over the allocation of shadow stacks for new threads, though; a patch series from Mark Brown may, after many attempts, finally be about to change that situation.

New restrictions on Android app sideloading

1 hét 6 nap óta
Google has announced a new set of restrictions on the ability of users to install apps on their own devices:

Starting next year, Android will require all apps to be registered by verified developers in order to be installed by users on certified Android devices. This creates crucial accountability, making it much harder for malicious actors to quickly distribute another harmful app after we take the first one down. Think of it like an ID check at the airport, which confirms a traveler's identity but is separate from the security screening of their bags; we will be confirming who the developer is, not reviewing the content of their app or where it came from.

We couldn't be more grateful for all who supported the Python ecosystem and helped make PyCon US 2025 a huge success.

[$] Linux's missing CRL infrastructure

1 hét 6 nap óta

In July 2024, Let's Encrypt, the nonprofit TLS certificate authority (CA), announced that it would be ending support for the online certificate status protocol (OCSP), which is used to determine when a server's signing certificate has been revoked. This prevents a compromised key from being used to impersonate a web server. The organization cited privacy concerns, and recommended that people rely on certificate revocation lists (CRLs) instead. On August 6, Let's Encrypt followed through and disabled its OCSP service. This poses a problem for Linux systems that must now rely on CRLs because, unlike on other operating systems, there is no standardized way for Linux programs to share a CRL cache.

Report: the state of commercial open source

2 hét óta
The Linux Foundation, in cooperation with a couple of other groups, has announced the publication on the intersection of businesses and commercial open-source software (deemed "COSS"). Everything, it seems, is great, and COSS companies make a lot of money for their investors.

Even more encouraging, COSS project communities continue along healthy growth paths after the company receives venture funding. In essence, highly valued COSS companies tend to cultivate more vibrant, diverse, and integral open source ecosystems, reinforcing the idea that business value and community value are tightly coupled in successful COSS models.
