[PATCH 0/1] libbpf dependecy for docker containers.

Posted by Andrew Melnychenko 3 years ago

For eBPF RSS steering, qemu required to be built with libbpf.
(https://lists.gnu.org/archive/html/qemu-devel/2021-03/msg08887.html)
So, for few docker containers there was added libbpf.
Some docker containers doesn't have that library, g.e. Ubuntu 20.04.
On some systems, like Centos7 or Debian, libbpf is pressent but doesn't
resolved as dependency by meson(may be pkg-config issues?).
On those systems qemu will be build without eBPF RSS steering.
The patch privedes changes for containers that able to build qemu
with libbpf: Alpine, Centos8 and Fedora.

  Added libbpf library to the docker files.
