As far as I know, rust-libbpf-cargo and below will need an update for
the Rust bindings for libbpf (which is not ready yet), so please just
ignore these for now.

Just recaping infos I got/researched for nixos.

note bcc upgrade in turns breaks gobpf, which indirectly breaks stuff
like oci-seccomp-bpf-hook.
gobpf got updated in https://github.com/iovisor/gobpf/pull/311
(unreleased, but we don't package it directly so we probably don't care)

oci-seccomp-bpf-hook got updated with it in v1.2.8 so that will need an
update. Didn't check if there are other reverse dependencies on gobpf in
fedora.
This one is backwards compatible, so the hook can be updated first with
no side effect.

(update with bcc 0.25 works, so just needs updating together with bcc.
Conversely older bpftrace does not work with bcc 0.25 iirc so it's not
just one after the other, but both together...)

knot got fixed in 3.2.1 and also "just" needs to be updated.
https://gitlab.nic.cz/knot/knot-dns/-/tags/v3.2.1

suricata got fixed in https://github.com/OISF/suricata/pull/7884
included in 7.0.0-beta1 last week, so will probably need to wait for an
actual release...
