Enabling CONFIG_CGROUP_BPF in kernel
Hi,
is it possible to enable CONFIG_CGROUP_BPF in Alpine’s kernel, please? It depends on CONFIG_BPF_SYSCALL which is also not set as of 3.9_rc1. Without these the ‘ip vrf exec’ command fails with following error:
router:~# ip link add VRF_A type vrf table 200
router:~# ip link set dev VRF_A up
[... assigning some interfaces to vrf here ...]
router:~# ip vrf exec VRF_A ping 1.2.3.4
Failed to load BPF prog: 'Function not implemented'
Kernel compiled with CGROUP_BPF enabled?
router:~#
It would be great if it made it into 3.9 released kernel, if it’s not too late. Thanks!
