dnsdist: Add the ability to retain select capabilities at runtime #10923

merged 1 commit into from
Nov 3, 2021


Copy link

Short description

This allows retaining the ability to create and use eBPF programs and maps at runtime, even if kernel.unprivileged_bpf_disabled is set, by keeping the CAP_BPF capability. It can be useful to prevent unprivileged programs on the system from loading eBPF while still allowing dnsdist to do so.
