In the nightly builds of Firefox, on the basis of which version 135 will be released on February 4th, the option allowing the transmission of the HTTP header 'Do Not Track' ('DNT') to websites has been removed from the privacy settings page (about:preferences#privacy). The DNT header informs websites of the user's desire not to share data that could be used to track movements and preferences. The reason for the removal is stated as […]

KVM: performance regressions and discussion on support for 32-bit systems

Posted on

An update has been accepted in the Linux 6.13-rc3 kernel that fixes a performance regression in the KVM hypervisor related to slow processing of CPUID calls on new CPUs. For example, on Intel Emerald Rapids CPUs, CPUID operations are performed 3-4 times slower than on Intel Skylake CPUs. This issue has led to reduced KVM hypervisor performance, which uses CPUID during the save process […]

Patches for reading balance in RAID1 using a Round-robin algorithm have been introduced for Btrfs.

Posted on

A set of patches implementing a cyclic balancing policy for read operations in RAID1, using a 'Round-robin' algorithm, has been accepted into the repository developing changes in Btrfs for future Linux kernel branches. To enable the distribution of read operations in a circular cycle, set the value 'round-robin:[min_contiguous_read]' in 'sys/fs/btrfs//read_policy', where the optional parameter 'min_contiguous_read' defines the minimum size of requests to be balanced between mirrors (by default […]

BadRAM attack, which allows bypassing the SEV-SNP attestation mechanism in AMD CPUs

Posted on

A group of researchers from the University of Leuven, University of Lübeck, and University of Birmingham has developed the BadRAM attack method (CVE-2024-21944), which allows bypassing authentication mechanisms and compromising environments protected using the SEV-SNP extension in AMD processors. To carry out the attack, the attacker typically must gain physical access to the memory modules and have the ability to execute code at ring 0 level […]

Fedora's initiatives for creating a desktop build with COSMIC and promoting Btrfs

Posted on

Starting with the release of Fedora 42, scheduled for spring next year, it has been proposed to create official Spin builds of the distribution with the COSMIC desktop environment developed in Rust. The proposal has not yet been considered by the FESCo (Fedora Engineering Steering Committee), which is responsible for the technical development of the Fedora distribution.
