Huawei proposes to launch a new sandbox mode for the Linux kernel
Reportedly, the Linux kernel has already tried Rust programming to improve memory security. Now, the Chinese tech giant Huawei is planning a proposal for a new “sandbox mode” for the Linux kernel to improve the C language code in the kernel. memory safety.
Linux emails show that Petr Tesarik of Huawei Cloud issued a “request for comments” patch series about the new sandbox mode. Petr described the sandbox mode as:
The ultimate goal of sandbox mode is to execute native kernel code in an environment that only allows memory access to predefined addresses, so potential vulnerabilities cannot be exploited or have no impact on the rest of the kernel.
This patch series adds sandbox-mode APIs and architecture-independent infrastructure to the kernel. It runs the target function on a vmalloc() copy of all input and output data. This alone prevents some out-of-bounds access due to the protected page.
The sandbox mode document description,
The main goal of Sandbox Mode (SBM) is to reduce the impact of potential memory safety bugs in the kernel code by breaking up the kernel. The SBM API allows each component to be run in an isolated execution environment. In particular, memory regions used as inputs and/or outputs are isolated from the rest of the kernel and surrounded by guard pages.
On an architecture that implements the necessary arch hooks, sandbox mode leverages hardware paging facilities and CPU privilege levels to force the use of only these predefined memory regions. With support from Arch, SBM can also recover from protection breaches. This means that SBM forcibly terminates the sandbox and returns an error code (such as “-EFAULT“) to the caller so that execution can continue. This implementation provides *strong isolation*.

Huawei officially announced the new FreeBuds Pro 4 headphones. This is the first TWS headset equipped with HarmonyOS NEXT and will be officially launched at the Huawei Mate Brand Festival on November 26.
As can be seen from the poster, the headset adopts an in-ear design with black and gold color matching, and the overall shape is similar to the previous generation. With the support of the new system, FreeBuds Pro 4 is expected to bring more functional upgrades.
For reference, Huawei FreeBuds Pro 3 was released in September last year with an initial price of 1,499 yuan . It is equipped with the Kirin A2 chip that uses Polar code, supports Star Flash connection core technology and Bluetooth technology, and the new L2HC 3.0 protocol.
