Hi,
I am configuring gre-port in my ovs bridge, for establishing gre-tunnel between
2 machines. I am trying to parse the tunnelling key params sent by OVS while
adding flow, when it sets action as OVS_ACTION_ATTR_SET. I am parsing the
tun-key attributes in dpif-linux.c in exact manner as ovs does, i.e.,
nla_data(nla_data(action)) where action is in "nlattr" type. Tun-key params
that I am trying to fetch are as per struct "ovs_key_ipv4_tunnel" i.e.,
struct ovs_key_ipv4_tunnel {
__be64 tun_id;
__be32 ipv4_src;
__be32 ipv4_dst;
__be16 tun_flags;
u8 ipv4_tos;
u8 ipv4_ttl;
};
The problem is that, while parsing I am getting incorrect tun-key params,
whereas I can see by putting prints that openvswitchd.ko is getting correct
tun-key params.
Please help how I can parse the tun-key params in my own dpif class plugin and
also let me know if I am parsing the tun-key params in correct manner.
Thanks
Chetan
