lwtunnels currently work only with gretap. This patchset fixes the bugs in ipgre metadata mode implementation.
As an example, in this setup: ip a a 192.168.1.1/24 dev eth0 ip l a gre1 type gre external ip l s gre1 up ip a a 192.168.99.1/24 dev gre1 ip r a 192.168.99.2/32 encap ip dst 192.168.1.2 ttl 10 dev gre1 ping 192.168.99.2 the traffic does not go through before this patchset and does as expected with it applied. Jiri Benc (3): gre: do not assign header_ops in collect metadata mode gre: build header correctly for collect metadata tunnels gre: receive also TEB packets for lwtunnels include/net/ip_tunnels.h | 1 + net/ipv4/ip_gre.c | 48 +++++++++++++++++++++++++++++++++--------------- 2 files changed, 34 insertions(+), 15 deletions(-) -- 1.8.3.1
