vpp-20.05 on up-to-date Centos 7.8 host with enforcing SELinux fails to
create a host-interface due to two missing SELinux-permissions:
vpp_t self:packet_socket { read write }
This simple patch adds these two permissions. Tested successfully on
local installation.
The steps to reproduce:
$ ip link add vpeer-host type veth peer name vpeer-vpp
vpp# create host-interface name vpeer-vpp
create host-interface: Permission denied (errno 13)
[...]
$ semodule -i vpp-packet-socket.pp
vpp# create host-interface name vpeer-vpp
host-vpeer-vpp
Type: fix
Ticket: VPP-1931
