net_util: ensure static configs have netmask in translate_network result
If a DataSource provides a network configuration in version 2 and runs
on a distro which does not have a network renderer class in use, then
the conversion of V2 to eni results in static ip configurations with
subnet prefix-length (192.168.23.1/24) rather than explicit netmask
value.
When sending such a config to net_util.translate_network the resulting
dictionary is missing the 'netmask' key for static configured addresses
breaking network configurations on multiple distributions.
This patch detects static ip configurations using prefix-length and
converts the format into the previous 'address' and 'netmask' parts
to keep compatibility for these distribtuions until they move to
the v2 network configuration.
Fall back to root:root on syslog permissions if other options fail.
If the user has removed the default configuration file or does
not set the syslog_fix_perms config option the user still ends
up with a warning on SUSE distributions. Add root:root to the
default builtin config.
At present the host network settings bleed into the test environment
causing the test test_handler_apt_source_v3 to fail if the host has a
domain setting other then localdomain.
There was a typo in the doc string at the top of ds-identify
(disable -> disabled). That is fixed here as well as adding some
better examples on content in /etc/cloud/ds-identify.cfg.
EphemeralIPv4Network: Be more explicit when adding default route.
On OpenStack based OVH public cloud, we got DHCP response with
fixed-address 54.36.113.86;
option subnet-mask 255.255.255.255;
option routers 54.36.112.1;
The router clearly is not on the subnet. So 'ip' would fail when
we tried to add the default route.
The solution here is to add an explicit route on that interface
to the router and then add the default route.
Also add 'bgpovs' to the list of 'physical' types for OpenStack
network configuration. That type is used on OVH public cloud.
OpenStack: support reading of newer versions of metdata.
Mark as supported for reading some newer versions of openstack metadata:
2016-06-30 : Newton one
2016-10-06 : Newton two
2017-02-22 : Ocata
2018-08-27 : Rocky
OpenStack: fix bug causing 'latest' version to be used from network.
Cloud-init was reading a list of versions from the OpenStack metadata
service (http://169.254.169.254/openstack/) and attempt to select the
newest known supported version. The problem was that the list
of versions was not being decoded, so we were comparing a list of
bytes (found versions) to a list of strings (known versions).
user-data: jinja template to render instance-data.json in cloud-config
Allow users to provide '## template: jinja' as the first line or their
#cloud-config or custom script user-data parts. When this header exists,
the cloud-config or script will be rendered as a jinja template.
All instance metadata keys and values present in
/run/cloud-init/instance-data.json will be available as jinja variables
for the template. This means any cloud-config module or script can
reference any standardized instance data in templates and scripts.
Additionally, any standardized instance-data.json keys scoped below a
'<v#>' key will be promoted as a top-level key for ease of reference in
templates. This means that '{{ local_hostname }}' is the same as using the
latest '{{ v#.local_hostname }}'.
Since instance-data is written to /run/cloud-init/instance-data.json, make
sure it is persisted across reboots when the cached datasource opject is
reloaded.
