Like vxlan and erspan opts, geneve opts should also be supported in
nft_tunnel. The difference is geneve RFC (draft-ietf-nvo3-geneve-14)
allows a geneve packet to carry multiple geneve opts. So with this
patch, nftables/libnftnl would do:
# nft add table ip filter
# nft add chain ip filter input { type filter hook input priority 0 \; }
# nft add tunnel filter geneve_02 { type geneve\; id 2\; \
ip saddr 192.168.1.1\; ip daddr 192.168.1.2\; \
sport 9000\; dport 9001\; dscp 1234\; ttl 64\; flags 1\; \
opts \"1:1:34567890,2:2:12121212,3:3:1212121234567890\"\; }
# nft list tunnels table filter
table ip filter {
tunnel geneve_02 {
id 2
ip saddr 192.168.1.1
ip daddr 192.168.1.2
sport 9000
dport 9001
tos 18
ttl 64
flags 1
geneve opts 1:1:34567890,2:2:12121212,3:3:1212121234567890
}
}
