Add support for VMware's vCD configuration setting DEFAULT-RUN-POST-CUST-SCRIPT.
When set True, it will default vms to run post customization scripts if the VM has not been configured in VMTools with "enable-custom-scripts" set False.
Add datasource documentation with a bit more context about this interaction on VMware products.
With this fix, the behavior will be:
* If VM administrator doesn't want others to execute a script on this VM, VMtools can set "enable-custom-scripts" to false from the utility "vmware-toolbox-cmd".
* If VM administrator doesn't set value to "enable-custom-scripts", then by default this script is disabled for security purpose.
* For VMware's vCD product , the preference is to enable the script if "enable-custom-scripts" is not set. vCD will generate a configuration file with "DEFAULT-RUN-POST-CUST-SCRIPT" set to true. This flag works for both VMware customization engine and cloud-init.

* cloudinit: remove global disable of pylint W0107 and fix errors
This includes removing a test class which contained no tests but wasn't
detected as empty because of an errant pass statement.
* .pylintrc: update disable comment to match arguments
|
|
Specifically:
* disable E1102 in cloudinit/sources/helpers/openstack.py for reasons
described in a comment, and
* refactor `abs_join` to require at least one positional argument; this
matches os.path.join's signature, and that mismatch is what was
causing pylint to emit a warning
* bump to pylint 2.4.2
|
|
As the first refactor PR, this also includes the initial structure for tests.

Hetzner cloud only supports user-data as a string (presumably utf-8).
In order to allow users on Hetzner to provide binary data to cloud-init,
we will attempt to base64decode the userdata.
The change here adds a 'maybe_b64decode' function that will decode data
if and only if is base64 encoded.
The reason for not using util.b64d is that we do not want the return value
decoded to a string, and util.b64d will do that if it can. Additionally
we call decode with validate=True which oddly is not the default.

This introduces a way to log the dhclient error stream, and uses it for the Azure datasource (where we have a specific requirement for this data to be logged).

deployPkg enable-custom-scripts", the return code will be EX_UNAVAILABLE(69), on this condition, it should not take it as error. (#413)

This was painful, but it finishes a TODO from cloudinit/subp.py.
It moves the following from util to subp:
ProcessExecutionError
subp
which
target_path
I moved subp_blob_in_tempfile into cc_chef, which is its only caller.
That saved us from having to deal with it using write_file
and temp_utils from subp (which does not import any cloudinit things now).
It is arguable that 'target_path' could be moved to a 'path_utils' or
something, but in order to use it from subp and also from utils,
we had to get it out of utils.

This fixes issues with closing brackets not matching the opening
bracket's line and continuation line under-idented for hanging indent.
|
|
This removes the use of variables named ‘l’, ‘O’, or ‘I’. Generally
these are used in list comprehension to read the line of lines.

We recently discovered that pylint is failing to report some errors when
invoked across our entire codebase (see
https://github.com/PyCQA/pylint/issues/3611). I've run pylint across
every Python file under cloudinit/[0], and this commit fixes the issues
so-discovered.

Azure stores the instance ID with an incorrect byte ordering for the
first three hyphen delimited parts. This results in invalid
is_new_instance checks forcing Azure datasource to recrawl the metadata
service.
When persisting instance-id from the metadata service, swap the
instance-id string byte order such that it is consistent with
that returned by dmi information. Check whether the instance-id
string is a byte-swapped match when determining correctly whether
the Azure platform instance-id has actually changed.

Headers param was accidentally omitted and no longer passed through to
readurl due to a previous commit.
To avoid this omission of params in the future, drop positional param
definitions from read_file_or_url and pass all kwargs through to readurl
when we are not operating on a file.
In util:read_seeded, correct the case where invalid positional param
file_retries was being passed into read_file_or_url.
Also drop duplicated file:// prefix addition from read_seeded because
read_file_or_url does that work anyway.

Router advertisements are required for the default route
to be set up, thus accept_ra should be enabled for
dhcpv6-stateful.
sysconf: IPV6_FORCE_ACCEPT_RA controls accept_ra sysctl.
eni: mode static and mode dhcp 'accept_ra' controls sysctl.
Add 'accept-ra: true|false' parameter to config v1 and
v2. When True: accept_ra is set to '1'. When False:
accept_ra is set to '0'. When not defined in config the
value is left to the operating system default.
This change also extend the IPv6 support to distinguish
between slaac and dhcpv6-stateless. SLAAC is autoconfig
without any options from DHCP, while stateless auto-configures
the address and the uses DHCP for other options.
LP: #1806014
LP: #1808647

Handle the special characters when reading VM Tools configure file.
For example, the key and value may contain _, - and . etc.
|
|
Openstack subnets can be configured to use SLAAC by setting
ipv6_address_mode=dhcpv6-stateless. When this is the case
the sysconfig interface configuration should use
IPV6_AUTOCONF=yes and not set DHCPV6C=yes.
This change sets the subnets type property to the full
network['type'] from openstack metadata.
cloudinit/net/sysconfig.py and cloudinit/net/eni.py
are updated to support new subnet types:
- 'ipv6_dhcpv6-stateless' => IPV6_AUTOCONF=yes
- 'ipv6_dhcpv6-stateful' => DHCPV6C=yes
Type 'dhcp6' in sysconfig is kept for backward compatibility
with any implementations that set subnet_type == 'dhcp6'.

VMWware customization already has support to run a custom script during
the VM customization. Adding this option allows a VM administrator to
disable the execution of customization scripts. If set the script
will not execute and the customization status is set to
GUESTCUST_ERROR_SCRIPT_DISABLED.
|
|
Collect and record the following information through KVP:
+ timestamps related to kernel initialization and systemd activation
of cloud-init services
+ system information including cloud-init version, kernel version,
distro version, and python version
+ diagnostic events for the most common provisioning error issues
such as empty dhcp lease, corrupted ovf-env.xml, etc.
+ increasing the log frequency of polling IMDS during reprovision.

cloud-init does not trigger reboots of a VM therefore adding custom
scripts to rc.local does not execute the post scripts. This patch
moves post-scripts into per-instance scripts dir and has cc_scripts
module run the post-scripts.
Also in this branch:
- Remove the sh interpreter and execute the customization script
directly.
- Update the unit test.

The Azure data source helper attempts to use information in the dhcp
lease to find the Wireserver endpoint (IP address). Under some unusual
circumstances, those attempts will fail. This change uses a static
address, known to be always correct in the Azure public and sovereign
clouds, when the helper fails to locate a valid dhcp lease. This
address is not guaranteed to be correct in Azure Stack environments;
it's still best to use the information from the lease whenever possible.

Create an Azure logging decorator and use additional ReportEventStack
context managers to provide additional logging details.
|

Some deployments of OpenStack expose link types to the guest which
cloud-init doesn't recognise. These will almost always be physical, so
we can operate more robustly if we assume that they are (whilst warning
the user that we're seeing something unexpected).
LP: #1639263

The Azure data source is expected to expose a list of
ssh keys for the user-to-be-provisioned in the crawled
metadata. When configured to use the __builtin__ agent
this list is built by the WALinuxAgentShim. The shim
retrieves the full set of certificates and public keys
exposed to the VM from the wireserver, extracts any
ssh keys it can, and returns that list.
This fix reduces that list of ssh keys to just the
ones whose fingerprints appear in the "administrative
user" section of the ovf-env.xml file. The Azure
control plane exposes other ssh keys to the VM for
other reasons, but those should not be added to the
authorized_keys file for the provisioned user.

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.
LP: #1806103

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.

OpenStack ironic references Infiniband interfaces via a 6 byte 'MAC
address' formed from bytes 13-15 and 18-20 of interface's hardware
address. This address is used as the ethernet_mac_address of Infiniband
links in network_data.json in configdrives generated by OpenStack nova.
We can use this address to map links in network_data.json to their
corresponding interface names.
When generating interface configuration files, we need to use the
interface's full hardware address as the HWADDR, rather than the 6 byte
MAC address provided by network_data.json.
This change allows IB interfaces to be referenced in this dual mode - by
MAC address and hardware address, depending on the context.
Support TYPE=InfiniBand for sysconfig configuration of IB interfaces.
|
|
Fix a bug where setting of mac address on a bond device was
ignored when provided in OpenStack network_config.json.

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.

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).

The issue is when customize a VM with static IPv4 and without gateway, it
will still extend route list and will loop a gateways list which is None.
This fix is to make sure when no gateway is here, it will not extend route
list.

This adds a Oracle specific datasource that functions with OCI.
It is a simplified version of the OpenStack metadata server
with support for vendor-data.
It does not support the OCI-C (classic) platform.
Also here is a move of BrokenMetadata to common 'sources'
as this was the third occurrence of that class.

The result of a read_file_or_url on a file and on a url would differ
in behavior.
str(UrlResponse) would return UrlResponse.contents.decode('utf-8')
while
str(FileResponse) would return str(FileResponse.contents)
The difference being "b'foo'" versus "foo".
As part of the general goal of cleaning util, move read_file_or_url
into url_helper.

This change will enable azure vms to report provisioning has completed
twice, first to tell the fabric it has completed then a second time to
enable customer settings. The datasource for the second provisioning is
the Instance Metadata Service (IMDS),and the VM will poll indefinitely for
the new ovf-env.xml from IMDS.
This branch introduces EphemeralDHCPv4 which encapsulates common logic
used by both DataSourceEc2 an DataSourceAzure for temporary DHCP
interactions without side-effects.

In the VMware customization workflow, we have some options for the user
to upload scripts for additional customization. Based on user request,
those custom scripts can be either run before regular customization or
after. For post customization scripts, we decide whether to run the scripts
just after customization or post system reboot.

Systems that used systemd-networkd's dhcp client would not be able to get
information on the Azure endpoint (placed in Option 245) or the CloudStack
server (in 'server_address').
The change here supports reading these files in /run/systemd/netif/leases.
The files declare that "This is private data. Do not parse.", but at this
point we do not have another option.

For customizing the machines hosted on 'VMWare' hypervisor, the datasource
should return the 'network config' data in 'curtin' format.
This branch also fixes /etc/network/interfaces replacing the line
"source /etc/network/interfaces.d/*.cfg" which is incorrectly removed
when VMWare's Perl Customization Engine writes /etc/network/interfaces.
Modify the code to read the customization configuration and return the
converted data.
Added few tests.

During boot, the usage of /tmp is not safe. In systemd systems,
systemd-tmpfiles-clean may run at any point and clear out a temp file
while cloud-init is using it. The solution here is to use
/run/cloud-init/tmp.

This feature enables the following VMware VCloud Director functionality:
1. Setting admin password
2. Expire password.
3. Set admin password and expire.
Password configuration is triggered only as part of a full
recustomization, that happens either on first power on or when
"poweron and full recustomization" is selected. Full customization
flow is determined by marker files. Unique marker ids are
generated when full recustomization is requested. And marker file based
on these marker ids help to determine if we need to execute the above
configuration.

Previously, the datasource for DigitalOcean allowed for a gateway on each
NIC. As a result, on Ubuntu 16.04, networking.service was broken. For
17.04 and later, Ubuntu _replaces_ the default gateway with the second
gateway on 'ifup' after reboot.
DigitalOcean is looking at changing the meta-data, however, this will
result in another version of the meta-data JSON.

This patch targets to make FreeBSD 10.3 or 11 work on Azure. The
modifications abide by the rule of:
* making as less modification as possible
* delegate to the distro or datasource where possible.
The main modifications are:
1. network configuration improvements, and movement into distro path.
2. Fix setting of password.
Password setting through "pw" can only work through pipe.
3. Add 'root:wheel' to syslog_fix_perms field.
4. Support resizing default file system (ufs)
5. copy cloud.cfg for freebsd to /etc/cloud/cloud.cfg rather than
/usr/local/etc/cloud/cloud.cfg.
6. Azure specific changes:
a. When reading the azure endpoint, search in a different path
and read a different option name (option-245 vs. unknown-245).
so, the lease file path should be generated according to platform.
b. adjust the handling of ephemeral mounts for ufs filesystem and
for finding the ephemeral device.
c. fix mounting of cdrom

This will change all instances of LOG.warn to LOG.warning as warn
is now a deprecated method. It will also make sure any logging
uses lazy logging by passing string format arguments as function
parameters.

Previously the IPv4LL address for metadata discovery was assigned to the
first interfaces from an alphabetic sort. On DigitalOcean, the metadata
is only accessible from the first interface. This fixes a problem where the
IPv4LL address is bound to the wrong interface with snapshots.
This is part of general improvements to the DigitalOcean Datasource in
bug 1676908.
