This patchset fixes a few 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.
v3: Back to v1 in order not to break existing users. Dropped patch 3, will
be fixed in iproute2 instead.
v2: Rejecting invalid configuration, added patch 3, dropped patch for
ETH_P_TEB (will target net-next).
Jiri Benc (2):
gre: do not assign header_ops in collect metadata mode
gre: build header correctly for collect metadata tunnels
