misc: selinux fixes (packet_socket r/w)
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 Change-Id: I2b3d92b27b9a9f26aa1c85af2946b15e83e27944 Signed-off-by: Martin Millnert <martin@millnert.se> (cherry picked from commit 68849350c56b0258d21fc906b09df71a1951f694)
