cloud-init trunk and xenial, yakkety, zesty and artful all fail
A network config with a ipv6 gateway route like:
subnets:
- type: static
address: 2001:4800:78ff:1b:be76:4eff:fe06:96b3
netmask: 'ffff:ffff:ffff:ffff::'
routes:
- gateway: 2001:4800:78ff:1b::1
netmask: '::'
network: '::'
For eni rendering, this should create a post-up/post-down route command that generates a default ipv6 route entry, like this:
post-up route add -A inet6 default gw 2001:4800:78ff:1b::1 || true
pre-down route del -A inet6 default gw 2001:4800:78ff:1b::1 || true
However, what is currently generated is this:
post-up route add -net :: netmask :: gw 2001:4800:78ff:1b::1 || true
pre-down route del -net :: netmask :: gw 2001:4800:78ff:1b::1 || true
That does not install the route correctly as a default gateway route.
This is fallout from commit d00da2d5b0d45db5670622a66d833d2abb907388
net: normalize data in network_state object
This commit removed ipv6 route 'netmask' values, and converted them to
prefix length values, but failed to update the eni renderer's check for
ipv6 default gateway. |
=== Begin SRU Template ===
[Impact]
Network configuration provided to cloud-init that has an ipv6 address
and additional manual default route will fail to bring up the routes
correctly.
[Test Case]
The basic idea below is:
a.) launch an instance with proposed version of cloud-init.
b.) inside instance, get cloud-init's network rendering tool from trunk
c.) run the rendering tool against a config that failed before.
d.) check rendered ENI config to verify it looks correct.
## launch an instance.
$ release=xenial
$ ref=$release-proposed
$ lxc-proposed-snapshot --proposed --publish $release $ref
$ lxc launch $ref $name
$ lxc exec $ref $name /bin/bash
## get render tool
% wget https://git.launchpad.net/~cloud-init-dev/cloud-init/plain/tools/net-convert.py -O net-convert.py
% cat > net-config.yaml <<"EOF"
version: 1
config:
- type: physical
name: eth0
mac_address: "c0:d6:9f:2c:e8:80"
subnets:
- type: static
address: "2001:1::2/64"
routes:
- gateway: "2001:4800:78ff:1b::1"
netmask: "::"
network: "::"
EOF
$ python3 ./net-convert.py \
--network-data=net-config.yaml --kind=yaml \
--output-kind=eni \
--mac=eth0,c0:d6:9f:2c:e8:80 \
--directory=out.d
% cat out.d/etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet6 static
address 2001:1::2/64
post-up route add -A inet6 default gw 2001:4800:78ff:1b::1 || true
pre-down route del -A inet6 default gw 2001:4800:78ff:1b::1 || true
## The output above is the expected output. The failure path
## would have post-up and pre-down like:
post-up route add -net :: netmask :: gw 2001:4800:78ff:1b::1 || true
pre-down route del -net :: netmask :: gw 2001:4800:78ff:1b::1 || true
[Regression Potential]
Regressions for this change are almost certainly limited to
rendering of ipv6 networking configuration and most likely limited
to routing.
