Currently the Linux kernel SECCOMP secure computing mode force-enables Spectre protections, which comes with obvious performance implications. When force-enabled, however, processes can't opt-out of the protection if they are not at risk to the likes of Spectre V4 "Speculative Store Bypass" issues. But a simple change being proposed would let such processes opt out if desired...

One of the most frequent critiques of Intel's Clear Linux distribution has been its lackluster support in dealing with proprietary/third-party packages like the Google Chrome web browser and Valve's Steam gaming client. Since last summer, Clear Linux has been working on their third-party packaging support with their unique "bundles" system, but not much has been heard on the matter since...

Feature work of Direct Rendering Manager (DRM) graphics driver work for Linux 5.7 is winding down now that Linux 5.6 is almost to its sixth release candidate this weekend, but sent in this week by AMD were a few more AMDGPU items though mostly amounting to fixes for their graphics driver...

In addition to WebAssembly's growing presence outside of the web browser thanks to various desktop run-times and interesting use-cases, WebAssembly is also popping up in other areas. Google has been working on WebAssembly support for extensions within network proxies typically reserved for C/C++ or the likes of Lua scripts...

On Tuesday the Load Value Injection (LVI) attack was disclosed by Intel and security researchers as a new class of transient-execution attacks and could lead to injecting data into a victim program and in turn stealing data, including from within SGX enclaves. While Intel has publicly stated they don't believe the LVI attack to be practical, one of their open-source compiler wizards did go ahead and add mitigation options to the GNU Assembler as part of the GCC toolchain. Here are benchmarks showing the performance impact of enabling those new LVI mitigation options and the significant impact they can cause on run-time performance in real-world workloads.

Yesterday the Load Value Injection (LVI) vulnerability was disclosed by Intel and researchers and affecting newer Intel CPUs with SGX and requiring mitigations outside of all the speculative execution mitigations the past two years. The GNU Assembler patches adding new options for mitigation have now been merged to Git master...

The newest open-source project out of Amazon Web Services is Bottlerocket, a Linux-based operating system designed for hosting containers and largely written in Rust code...

We've known that Intel's P-State Linux CPU frequency scaling driver in general can be a bit quirky and especially so when dealing with Intel integrated graphics where the iGPU and CPU share the same power envelope. This has been shown with examples like using the "powersave" governor to boost iGPU performance while discrete graphics owners are generally best off switching over to the "performance" governor. As the latest though on helping the iGPU front with P-State, there is a new patch series talking up big gains in performance and power efficiency...

Load Value Injection (LVI) is being disclosed today as a new class of transient-execution attacks and the researchers claim can defeat all existing mitigations around Meltdown, Foreshadow, Zombieload, RIDL and Fallout. The researchers say LVI can affect virtually any access to memory and compiler-based mitigations can be expensive...

With the Linux 5.7 kernel this spring there is going to be a new exFAT file-system drive developed by Samsung as outlined last week. While that is being added to the formal file-system area of the kernel rather than staging so both could co-exist for a transition period, already with Linux 5.7 will be the removal of the existing staging driver...
