Several nodes with "multi" type contain extra space character after
the `multi:` mark, which prevents the `cc_vyos_userdata` module to
detect their type properly. This commit changes the regex used for
detecting such nodes to fix the problem.

Appending all the data from `metadata_ds['public-keys']` to a list of public keys is dangerous because some of the other datasources have the same `public-keys` option but use different formats inside. Thus, the workaround was limited to Azure datasource only.

After the commit 377d1bbbdd45aad25c36ab15ce15c93a39df4ce9 dhclient should be run by Cloud-init properly even without calls from datasources, if this is necessary.
This change solves the problems caused by always active dhclient on eth0 interface when Ec2, GCE, or Azure datasource is used.

On Debian, ifupdown uses `source-directory /etc/network/interfaces.d`
(for new installs) to include files.
https://salsa.debian.org/debian/ifupdown/blob/master/debian/postinst#L23
The current filename, 50-cloud-init.cfg, does not match against the RE
that is used to scan the directory for configurations (ASCII upper- and
lower-case letters, ASCII digits, ASCII underscores, and ASCII
minus-hyphens):
https://salsa.debian.org/debian/ifupdown/blob/master/interfaces.5.pre#L122
Of course many installations use `source /etc/network/interfaces.d/*`,
but not all.

The behavior of VyOS modules was almost totally changed. Therefore instead of changes, here is a list of what is supported by new versions:
`cc_vyos.py`:
- extended logging for debugging purposes
- work with any environment or datasource
- all available in VyOS SSH keys (ssh-dss, ssh-rsa, ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ssh-ed25519, ecdsa-sha2-nistp521) with options
- both encrypted and plain-text passwords
- multiple user accounts
- the fallback user creating (default "vyos/vyos") in credentials are missed in a Meta-Data
- interfaces configuration using Network-Config v1 or v2
- fallback interface config (DHCP on eth0) if Network-config is not available
- both IPv4 and IPv6 addresses in Network-Config
- MTU, multiple addresses, DHCP or static addresses, gateway, routes, DNS nameserver, DNS search domain in Network-Config
- filtration of a hostname value from metadata
- VyOS-specific options from the OVF template
- automatically enabling SSH server
`cc_vyos_userdata.py`:
set and delete configuration commands inside the User-Data (#cloud-config). See details: https://github.com/vyos/vyos-cloud-init/commit/1607eec32641ad93ea211e447336b3366c28de06
Configuration template:
- enabled `write_files` module
- disabled the `runcmd` module (functionality replaced by `cc_vyos_userdata.py` and `write_files`)

Transport functions (transport_iso9660 and transport_vmware_guestinfo)
would return a tuple of 3 values, but only the first was ever used
outside of test. The other values (device and filename) were just
ignored.
This just simplifies the transport functions to now return content
(in string format) or None indicating that the transport was not found.
|
|
This adds support for reading OVF information over the
'com.vmware.guestInfo' tranport. The current implementation requires
vmware-rpctool be installed in the system.

It is possible to have a metric value in a per-subnet route.
This is currently missing in all renderers. Update each
renderer to emit the correct metric value from the config.

Add 'append: true' to write_files entries to append 'content' to file
specified by 'path' key. This modifies the file open mode to append.

I noticed a bug in dhclient_hook on the 'down' event, using 'is'
operator rather than '==' (if self.net_action is 'down').
This refactors/simplifies the code a bit for easier testing and adds
tests. The reason for the rename of 'action' to 'event' is to just
be internally consistent. The word and Namespace 'action' is used
by cloud-init main, so it was not really usable here.
Also adds a main which can easily be debugged with:
CI_DHCP_HOOK_DATA_D=./my.d python -m cloudinit.dhclient_hook up eth0

NoCloud's 'network-config' file was originally expected to contain
network configuration without the top level 'network' key. This was
because the file was named 'network-config' so specifying 'network'
seemed redundant.
However, JuJu is currently providing a top level 'network' config when
it tries to disable networking ({"network": {"config": "disabled"}).
Other users have also been surprised/confused by the fact that
a network config in /etc/cloud/cloud.cfg.d/network.cfg differed from
what was expected in 'network-config'.

Move routes under the nic's subnet rather than use top-level
("global") route config ensuring all net renderers will provide the
configured route.
Also updated cloudinit/cmd/devel/net_convert.py:
- Add input type 'vmware-imc' for OVF customization config files
- Fix bug when output-type was netplan which invoked netplan
generate/apply and attempted to write to
/etc/netplan/50-cloud-init.yaml instead of joining with the
output directory.

Replace Azure pre-provision polling on IMDS with a blocking call
which watches for netlink link state change messages. The media
change event happens when a pre-provisioned VM has been activated
and is connected to the users virtual network and cloud-init can
then resume operation to complete image instantiation.

Check the appropriate variables based on code review. Correcting what
seems to be a copy/paste mistake for the error handling from a few lines
above.

Since /run/cloud-init/instance-data-sensitive.json is root read-only,
ignore this file if non-root user runs collect-logs.
If --include-userdata is provided on the command line, exit in error
if non-root user attempts this operation.
Lastly, update the __main__ to exit based on return value of main.
LP: #1805201

We add a new Optional parameter: connectivity_url
This is used in __enter__ to verify if a connection already exists.
If it does exist, no operations are performed.
|
|
Upon URL timeout, _poll_imds is expected to re-dhcp to get updated
IP configuration. We don't want to indefinitely retry because the
instance likely has invalid IP configuration.

In some environments, like FreeBSD, gpart can return the device basename
instead of the full path. If this discovered devpath does not exist and
is missing the '/dev/' prefix, add that prefix in an attempt to find the
device.

There is an infrequent race when the booting instance can hit the IMDS
service before it is fully available. This results in a
requests.ConnectTimeout being raised.
Azure's retry_callback logic now retries on either 404s or Timeouts.

If Azure detects an ntfs filesystem type during mount attempt, it should
still report the resource device as reformattable. There are slight
differences in error message format on RedHat and SuSE. This patch
simplifies the expected error match to work on both distributions.

In commitish 9073951 azure datasource tried to leverage stale DHCP
information obtained from EphemeralDHCPv4 context manager to report
updated provisioning status to the fabric earlier in the boot process.
Unfortunately the stale ephemeral network configuration had already been
torn down in preparation to bring up IMDS network config so the report
attempt failed on timeout.
This branch introduces obtain_lease and clean_network public methods on
EphemeralDHCPv4 to allow for setup and teardown of ephemeral network
configuration without using a context manager. Azure datasource now uses
this to persist ephemeral network configuration across multiple contexts
during provisioning to avoid multiple DHCP roundtrips.

There was a typo in the seeded filename s/azure-hotplug/hotplug-azure/.
|
|
When reusing a preprovisioned VM, report ready to Azure fabric as soon as
we get the reprovision data and the goal state so that we are not delayed
by the cloud-init stage switch, saving 2-3 seconds. Also reduce logging
when polling IMDS for reprovision data.

Emit a permissions error instead of "Missing instance-data.json" when
non-root user doesn't have read-permission on
/run/cloud-init/instance-data.json
|
|
On cloud-init upgrade path from 18.3 to 18.4 cloud-init changed how
instance-data is written. Cloud-init changes instance-data.json from root
read-only to redacted world-readable content, and provided a separate
unredacted instance-data-sensitive.json which is read-only root.
Since instance-data is only rewritten from cache on
reboot, the query and render tools needed fallback to use the 'old'
instance-data.json if the new sensitive file isn't yet present.
This avoids error messages from tools about an absebt
/run/instance-data-sensitive.json file.

Azure generates network configuration from the IMDS service and removes
any preexisting hotplug network scripts which exist in Azure cloud images.
Add a datasource configuration option which allows for writing a default
network configuration which sets up dhcp on eth0 and leave the hotplug
handling to the cloud-image scripts.
To disable network-config from Azure IMDS, add the following to
/etc/cloud/cloud.cfg.d/99-azure-no-imds-network.cfg:
datasource:
Azure:
apply_network_config: False
