Originally created by @lfarkas on GitHub (Sep 11, 2023).

running on home assistant in a docker container it gives this error:

2023-09-11T18:16:30+02:00 WARN client/internal/wgproxy/factory_linux.go:15: failed to initialize ebpf proxy, fallback to user space proxy: field NbXdpProg: program nb_xdp_prog: load program: permission denied: 12: (2d) if r2 > r1 goto pc+148: R1 pointer comparison prohibited (21 line(s) omitted)

i use these privileges during docker run:

NET_ADMIN
NET_RAW
BPF
but not
SYS_ADMIN
SYS_RAWIO
since those are not required according to:

Hello @lfarkas!
Based on the documentation the SYS_ADMIN and SYS_RESOURCE capabilities are required. Could you take a try with it?
