Comparing Security in eBPF and WebAssembly [PDF]
Proceedings of the 1st Workshop on eBPF and Kernel Extensions, 2023 This paper examines the security of eBPF and WebAssembly (Wasm), two technologies that have gained widespread adoption in recent years, despite being designed for very different use cases and environments. While eBPF is a technology primarily used within operating system kernels such as Linux, Wasm is a binary instruction format designed for a stack ...

CoRR, 2023 The eBPF technology in the Linux kernel has been widely adopted for different applications, such as networking, tracing, and security, thanks to the programmability it provides. By allowing user-supplied eBPF programs to be executed directly in the kernel, it greatly increases the flexibility and efficiency of deploying customized logic.

Photonic‐assisted one‐third microwave frequency divider
Electronics Letters, Volume 58, Issue 16, Page 627-629, August 2022., 2022 Abstract A microwave photonic frequency divider to produce a frequency‐divided microwave signal with its frequency that is one‐third the frequency of the input microwave signal is proposed and experimentally demonstrated. The key novelty of the approach is that the phase control, a condition to realise the frequency division operation, is implemented ...

Practical and Flexible Kernel CFI Enforcement using eBPF
, 2023 Enforcing control flow integrity (CFI) in the kernel (kCFI) can prevent control-flow hijack attacks. Unfortunately, current kCFI approaches have high overhead or are inflexible and cannot support complex context-sensitive policies.

Unleashing Unprivileged eBPF Potential with Dynamic Sandboxing [PDF]
, 2023 For safety reasons, unprivileged users today have only limited ways to customize the kernel through the extended Berkeley Packet Filter (eBPF). This is unfortunate, especially since the eBPF framework itself has seen an increase in scope over the years ...

Programmable System Call Security with eBPF
CoRR, 2023 System call filtering is a widely used security mechanism for protecting a shared OS kernel against untrusted user applications. However, existing system call filtering techniques either are too expensive due to the context switch overhead imposed by userspace agents, or lack sufficient programmability to express advanced policies.

Buzzy: An Unguided Smart-Strategy Generation-Based Blackbox Fuzzer for eBPF Technologies: Buzzy: Fuzz Testing eBPF Technologies [PDF]
, 2023 eBPF is a groundbreaking technology in the Linux kernel. It facilitates programmers to load programs into the kernel that, after a verification step, can JIT compile and execute the eBPF program.
