Description of the change

This is to update the Chef examples and changes for the newer/est ways
Chef is converting to. Omnibus is now the default installation method, but
there are also more up-to-date package repos at packagecloud.io if the user
still wants to install the deb package.

I have also added the encrypted_data_bag option to the client.rb being that
it is a useful option to have for more secure environments.

Convert dmidecode values to sysfs names before looking for them.

dmidecode and /sys/class/dmi/id/* use different names for the same
information. This modified the logic in util.read_dmi_data to map from
dmidecode names to sysfs names before looking in sysfs.

pull in 'snappy' support

This allows config to disable some of the config modules that were

Fix hang caused by HTTPretty on Python 3.4.2.

HTTPretty can causes hangs on Python 3.4.2 (and maybe Python 3.4.1), due
to a Python bug (fixed in Python 3.4.3). This works around the problem
in the appropriate Python versions.

See https://github.com/gabrielfalcao/HTTPretty/pull/193 and
https://github.com/gabrielfalcao/HTTPretty/issues/221 for details.

snappy: disable by default

userdata-handlers: python3-related fixes on do-not-process-this-part path

Cloud-init crashed when received multipart userdata object with
'application/octet-stream' part or some other 'application/*' part
except archived ones (x-gzip and friends). These parts are not
processed by cloud-init and result only in a message in the log.
We used some non-python3-friendly techniques while generating
this log message which was a reason for the crash.

NoCloud: the local portion of NoCloud incorrectly claimed datasources

The intent has always been for the local datasource (NoCloud) to require
the provider of metadata to provide 'dsmode=local'. If that wasn't found,
then the default 'dsmode' would be 'net', and the NoCloudNet datasource
would then find the data.

The bug here was that the default 'net' wasn't being set when
data was found on a local source.

fix snappy package installation.

Some tests added here to make sure this works.
The install '--config' will only start to work with the next
version of snappy-go.

adjust cc_snappy for snappy install package with config.

It was believed that to install a package with config the command was:
  snappy install --config=config-file <package>
Instead, what was implemented in snappy was:
  snappy install <package> [<config-file>]

This modifies cloud-init to invoke the latter and changes the tests
appropriately.

systemd: use network-online instead of network.target (LP: #1440180)

network-online.target.

fix cloud-config-archive handling

handling of cloud-config-archive input would fail in fully_decoded_payload.
part.get_charset() would return a Charset object, but
get_charset.input_codec is a string suitable for passing to decode.

This handles that correctly, and is more careful about binary data inside
input.

The test added verifies that cloud-config inside a cloud-config-archive
is handled correctly and also that binary data there is ignored without
exceptions raised.

sysvinit: make cloud-init-local run before networking is brought up

While booting a VM from a snapshot image, network service use to find the
residual network config scripts and use to configure the old IPs.
cloud-init-local use to run later and populate the config scripts with latest
information, which does not override the previous configuration.

To solve this, we are ensuring that cloud-init-local runs before network.

Azure: remove dependency on walinux-agent

This takes away our dependency on walinux-agent, by providing a builtin

check for systemd using sd_booted() semantics

The existing code determines if systemd is in use by looking at the
distribution name and version. This is prone to error because:
- RHEL derivatives other than CentOS (e.g., Scientific Linux) will fail
  this test
- Distributions that are not derived from RHEL also use systemd

This patch makes cloud-init use the same logic that is used in systemd's
sd_booted() method

tests: fix TestHandlerHandlePart tests

these tests were previously passing, but doing so erroneously.
I believe that an update to mock caused them to start failing.

I've updated the tests now. The simple change is
replacing 'assert_called_with_once' with 'assert_called_once_with'.

The second set of changes is seemingly a correction of the following tests
expectations:
 test_normal_version_2 : was not expecting to get frequency passed into
    handle_part, but should have been.
 test_no_handle_when_modfreq_once: was expecting to have handle_part
    called even though the test implies otherwise.
 test_exception_is_caught: this test just looked broken.
    Now, we're testing that the part handler is called and that no
    exception is raised past handle_part

provide data source to mirror selection code for region-specific mirrors.

mounts: support reliably detecting and using Azure ephemeral disks

Azure's ephemeral disks are not guaranteed to be assigned the same name by
the kernel every boot. This causes problems on ~2% of Azure instances, and
can be fixed by using udev rules to give us a deterministic path to mount;
this patch introduces those udev rules and modifies the Azure data source
to use them.

Changes to a couple of config modules were also required. In some places,
they just needed to learn to dereference symlinks. In cc_mounts this
wasn't sufficient because the dereferenced device would have been put in
/etc/fstab (rather defeating the point of using the udev rules in the
first place). A fairly hefty refactor was required to separate "is this a
valid block device?" from "what shall I put in fstab?".

Handle symlink mount points in mount_cb.

The Azure data source now uses a /dev/disk symlink to identify devices,

mount_cb therefore doesn't identify when a disk is already mounted, and
attempts to mount it a second time (which fails with NTFS).

Azure: get instance id from dmi instead of SharedConfig

Replace the use of SharedConfig.xml in both the walinuxagent case,

Those versions should have a file /etc/localtime . When the symlink

Additionally it seems we no longer need this strange line.

systemd: support disabling cloud-init via file or kernel cmdline

This adds a systemd generator for a 'cloud-init.target'. That target will
be WantedBy multi-user.target in the default case. If there is a file
/etc/cloud/cloud-init.disabled or the kernel command line contains
'cloud-init=disabled' then cloud-init will not affect boot at all.

There are some packages/debian changes to affect this:
 * postinst, preinst: these are necessary to remove some
   old target files for multi-user.target (LP: #1552999)

Apply pep8, pyflakes fixes for python2 and 3

Update make check target to run pep8 and run pyflakes or pyflakes3
depending on the value of 'PYVER'. This way the python3 build

No longer run pollinate by default in seed_random

The user can still choose to run pollinate here to seed their
random data. And in an environment with network datasource, that
would be expected to work. However, we do not want to run it any
more from cloud-init because
a.) pollinate's own init system jobs should get it ran before ssh,
    which is the primary purpose of wanting cloud-init to run it.
b.) with a local datasource, there is no network guarantee when
    init_modules run, so pollinate -q would often cause issues then.
c.) cloud-init would run pollinate and log the failure causing
    many cloud-init specific failures that it could do nothing about.

Additionally, add documentation for the seed_random config module.

add default user to 'lxd' group and create groups when necessary.

This add 'lxd' to the list of groups that the default user is added to.
It also changes behavior to create any necessary groups that are listed
for the user rather than failing to add the user.

Theres also a fix for usage of logexc that I found along the way.

dmi data: fix failure of reading dmi data for unset dmi values

it is not uncommon to find dmi data in /sys full of 'ff'. utf-8
decoding of those would fail, causing warning and stacktrace.

Return '.' instead of \xff. This is what dmidecode would return.

$ dmidecode --string system-product-name

1181. By Scott Moser on 2016-03-14

change return value for dmi data of all \xff to be ""

Previously we returned a string of "." the same length as the dmi field.
That seems confusing to the user as "." would seem like a valid response
when in fact this value should not be considered valid.

So now, in this case, return empty string.

some systemd cleanups

 generator:
  * write to directory /run/cloud-init/ rather than /run
  * read from /proc/1/cmdline for the command line if inside a container

 cloud-init-local.service: now run fully before any networking comes up.
 cloud-init.service: run before network-online.target and after
    networking.service. This ends up meaning other things that require
    network-online.target will run after cloud-init.service, but
    cloud-init.service will still have networking.

    The 'networking.service' is ifupdown specific. Further changes would
    be needed for other networking systems (networkd for example)

Add option checking for ssh_pwauth to bring behavior inline with the

debian packaging: adjust build-depends for xenial

python3 support was moved out of pyflakes into python3-pyflakes.
Adjust the package to build on trusty where python3-pyflakes was
not present and also on xenial where it is.

Note, this does mean that sbuild now requires '--resolve-alternatives'.
That is how it is used on launchpad but is not the default in sbuild.

quickly check to see if the previous instance id is still valid

This adds a check in cloud-init to see if the existing (cached)
datasource is still valid. It relies on support from the Datasource
to implement 'check_instance_id'. That method should quickly determine
(if possible) if the instance id found in the datasource is still valid.

This means that we can still notice new instance ids without
depending on a network datasource on every boot.

I've also implemented check_instance_id for the superclass and for
sources:
  DataSourceAzure (check dmi data)
  DataSourceConfigDrive (check dmi data)
  DataSourceNocloud (check the seeded data or kernel command line)
  DataSourceOpenstack (check dmi data)

1189. By Scott Moser on 2016-03-24

support network configuration in cloud-init --local

this allows 'cloud-init --local' to fully run before networking comes up.
By doing so, we can now cleanly apply networking to the new system.

This adds support for reading ConfigDrive network configuration
and also from NoCloud. The support is only present for ubuntu/debian
at the current time. Other distros will follow.

Also ability to specify network configuration on kernel command line
via either ip= or network-config=<base64>.

1190. By Scott Moser on 2016-03-29

improve how cloud-init-wait waits

Instead of sleep and check loop, use 'udevadm settle' to wait.
since we run from a udev event, this is sufficient.
udev settle will exit when either of
   a.) the file exists
   b.) the udev event queue has all been processed.
   c.) timeout is reached.

Since cloud-init-wait is being run as a udev event, 'b' cannot
be satisfied until it finishes. Thus, this essentially becomes a
inotify based wait for the file /run/cloud-init/network-config-ready
and no loops are needed.

1191. By Scott Moser on 2016-03-29

apply_network_config improvements

3 things here:
 a.) do not raise exception, only warn when trying to apply a network
     config for a distro that does not have an implementation.
     This is important since debian/ubuntu is the only one *with* an
     implementation at the moment
 b.) apply network config in 'cloud-init --local' even if there is
     no datasource found. This means that the fallback datasource has
     to get things right.
 c.) do not write 70-persistent-net.rules
     the code was writing both 70-persistent-net.rules and
     /etc/systemd/network/50-cloud-init-*.link files
     that would just be confusing.

fix adding of users when no group is specified

revision 1179 regressed adding a user that did not have a 'groups'
entry present in cloud-config.
This handles that correctly, making 'add_user' able to take:
  a.) groups="group1,group2"
  b.) groups=["group1", "group2"]
  c.) groups=None
  d.) no groups parameter

Additionally, if a primary group is specified it will also be created.

End result is that this is functional:
 #cloud-config
 groups: ["sudo"]
 users:
   - name: sysop
     primary-group: sysop
     groups: "sudo,adm"
     shell: /bin/bash
   - name: user1
     primary-group: users
     groups: sudo
   - name: foo1
   - name: bar
     gecos: Bar
     groups: ["bargroup"]

Resulting in:
 $ groups sysop
 sysop : sysop adm sudo
 $ groups user1
 user1 : users sudo
 $ groups foo1
 foo1 : foo1
 $ groups bar
 bar : bar bargroup

Ensure that a resolve conf object is written as a string.

DataSourceNoCloud: fix check_instance_id when upgraded

A system that had booted, upgraded, and then rebooted would show
a cloud-init stack trace as it attempted to run new code
with the old pickled object. The old object would not have the
seed_dirs attribute. So we check and fallback correctly if that
is not present.

SmartOS, CloudSigma: fix error when dmi data is not availble

rh_subscription: only check subscription if configured

The rh_subscription config module would attempt to connect to the RHN servers

That consists of username and password or a activation key.

1206. By Scott Moser on 2016-04-13

skip bridges when generating fallback networking

It does not make sense to consider bridges when searching for fallback
networking. If the system is configured with a bridge, then its probably
for some purpose other than to get to a metadata service.

Considering the bridge could make cloud-init pick the wrong device on reboot.

chef: straighten out validation_cert and validation_key

Now, validation_key is always a path to a file, as it is in

validation_cert is always the *content* of that file that should
be written. However, if validation_cert is the string "system",
then we do not write that value, but rather assume the file exists.

fallback net config: do not consider devices starting with 'veth'

networking: no longer delete eth0.cfg on debian/ubuntu

Ubuntu cloud images in created a file during build that
would interfere with cloud-init's discovered or rendered networking.
To avoid the issues, cloud-init was deleting
/etc/network/interfaces.d/eth0.cfg .

The build process no longer creates this file.
However, to address any existing files cloud-init will still remove
the file if it has known content and warn otherwise.

1211. By Scott Moser on 2016-04-15

apply networking less often

Do not apply networking configuration whenever a previous datasource
has been loaded from disk and found to be valid (via positive
 return 'check_instance_id' or user configuration of manual_cache_clean).

This effectively means that we apply fallback networking only once
per instance rather than every boot on any datasource with
'check_instance_id' implemented.

1212. By Scott Moser on 2016-04-15

network: do not write interface as 'auto' from ip= on command line.

When ip= on the kernel command line defines the networking, set
those network devices to be manually controlled, instead of 'auto'.

The reason for this is that if they're marked as 'auto':
 a.) a second attempt will be made to ifup them.
 b.) they'll be brought down on shutdown

'b' is problematic on network root filesystem.

Also this picks up 2 changes from curtin's net module:
  - Cleanup newline logic so we always have a clean '\n\n' between stanza
  - Add a unittest to validate bonding network config render, specifically
    when to emit auto $iface for dependent bond slaves.

The change to get_instance_userdata is to fix an issue that
was causing retry in the test when it was not desired.
if user_data returned 404 it means "there was no user-data", so
dont bother retrying. However, _skip_retry_on_codes was returning
False indicating that readurl should retry.

test_merging was creating 2500 random tests, shrink that down to 100.
test_seed_runs is still on my system the slowest test, but
taking < .5 seconds where it was taking > 3.

improve network configuration

This branch accomplishes several things:
 - centrally handle 'dsmode' to be 'local' or 'net.
   This allows local data sources to run before networking
   but still have user-data read by default when networking is available.

 - support networking information being read on dreamcompute
   dreamcompute's openstack declares networking via the
   /etc/network/interfaces style 'network_config' format.

 - support reading and applying networking information on SmartOS

 - improve reading networking from openstack network_data.json (LP: #1577982)
   add support for mtu and routes and many miscellaneous fixes.

 - support for renaming devices in a container (LP: #1579130).
   Also rename network devices as instructed by the host on
   every boot where cloud-init networking is enabled. This is required
   because a.) containers do not get systemd.link files applied
   as they do not have udev. b.) if the initramfs is out of date
   then we need to apply them.

 - remove blocking of udev rules (LP: #1577844, LP: #1571761)

Change missing Cheetah log warning to debug [Andrew Jorgensen]

In the absence of cheetah, which is a fairly heavy templating engine, and

message makes any other warnings more relevant.

 - harden mirrorfail tests to detect and skip if no network is available
 - improve apt_source related tests to work on CentOS7

   to its own module.
 - packages/bddeb has an option to sign as someone else than smoser
 - make exception handling of apt_source features more specific

Refactor a large part of the networking code.

Splits off distro specific code into specific files so that
other kinds of networking configuration can be written by the
various distro(s) that cloud-init supports.

It also isolates some of the cloudinit.net code so that it can
be more easily used on its own (and incorporated into other
projects such as curtin).

During this process it adds tests so that the net process can
be tested (to some level) so that the format conversion processes
can be tested going forward.

do not render systemd.link files

When fixing bug 1579130, we made cloud-init rename devices itself,
rather than relying on the systemd.link files to do that.
That was necessary to
 - rename devices in a container
 - rename devices on first boot or in any situation when the
   link files in the initramfs were stale.

However, cloud-init was still writing .link files like:
 /etc/systemd/network/50-cloud-init-ens2.link

That leads to just a confusing situation as cloud-init will trump
any renaming systemd does in all cases.

Also added here is a header into the rendered ENI file:
 /etc/network/interfaces.d/50-cloud-init.cfg

that describes how to disable cloud-init networking.

ConfigDrive: fix writing of 'injected' files and legacy networking

Previous commit inadvertently disabled the consumption of 'injected' files
in configdrive (openstack server boot --file=/target/file=local-file)
unless the datasource was in 'pass' mode. The default mode is 'net' so
that was not likely to happen.

Also here are:
a.) some comments to apply_network_config

b.) add backwards compatibility for distros that do not yet implement
    apply_network_config by converting the network config into ENI format
    and calling apply_network.

    This is required because prior to the previous commit, those distros
    would have had 'apply_network' called with the openstack provided
    ENI file. But after this change they will have apply_network_config
    called by cloudinit's main.

c.) add network_state_to_eni for converting net config to eni
    it supports the not-actually-correct 'hwaddress' field in ENI

improvements to eni rendering

Some improvements here, and some bug fixes.
 - bring curtin revno 394's to support post-up for interface aliases.
 - sort attributes per interface for nicer order and consistent rendering
 - use arrays for each 'section' rather than content += . This allows
   better separation of the sections and also will perform better as long
   strings with += are slow.
 - improve how 'lo' is handled. If a network state that was being rendered
   had an entry for 'lo', then the rendered ENI would have 2 'lo'
   sections.
 - no longer skip 'lo' sections when loading an ENI in parse_deb_config
 - fix inet value for subnets, don't add interface attributes to alias
   (LP: #1588547)

Also add some tests of reading yaml and rendering ENI.

Avoid depending on argparse in 2.7 or greater

At least (currently) for rhel7 the argparse package does
not get installed (even though rpm say it is installed by
the python core package) and this causes things that mention
argparse in there requirements to not believe that argparse
is installed (even though it is) so to avoid this whole mess
we can just avoid depending on argparse in python versions
where we don't need to (since it was included in the stdlib
in python 2.7+)

mcollective: add tests, cleanups and bug fix when no config in /etc.

Things here:
 - restart rather than 'start' the service, to pick up a config change
   that we would have written.
 - update the config and write cert files whether or not the file
   existed on the system. Previously it would only write the cert
   files if /etc/mcollective/server.cfg already existed.
 - improve test coverage
