Also, add the "signed by" option to source definitions. This enables
users to limit the scope of trust for individual keys.

When ssh host keys are generated during initial boot the full output of
ssh-keygen, including the randomart for the key, is displayed on the
console for each of the generated key types, which takes up a large
amount of screen output (17 lines per key type).
With this change ssh-keygen output is still displayed by default.
Setting ssh_quiet_keygen to True will prevent ssh-keygen output from
appearing. If only the fingerprints of the host keys should be
displayed then this can be achieved using the existing
emit_keys_to_console and/or ssh_fp_console_blacklist settings.

This commit removes automatically installing udev rules for hotplug
and adds a module to install them instead.
Automatically including the udev rules and checking if hotplug was
enabled consumed too many resources in certain circumstances. Moving the
rules to a module ensures we don't spend extra extra cycles on hotplug
if hotplug functionality isn't desired.

The main idea is to introduce a second module that takes care of
writing files, but in the 'final' stage.
While the introduction of a second module would allow for choosing
the appropriate place withing the order of modules (and stages),
there is no addition top-level directive being added to the cloud
configuration schema. Instead, 'write-files' schema is being extended
to include a 'defer' attribute used only by the 'write-deffered-files'
modules.
The new module 'write-deferred-files' reuses as much as
possible of the 'write-files' functionality.
|

Various modules restart services and they all have logic to try and
detect if they are running on a system that needs 'systemctl' or
'service', and then have code to decide which order the arguments
need to be etc. On top of that, not all modules do this in the same way.
The duplication and different approaches are not ideal but this also
makes it hard to add support for a new distribution that does not use
either 'systemctl' or 'service'.
This change adds a new manage_service() method to the distro class
and updates several modules to use it.

When default host keys are created by sshd-keygen (/etc/ssh/ssh_host_*_key)
in RHEL/CentOS/Fedora, openssh it performs the following:
# create new keys
if ! $KEYGEN -q -t $KEYTYPE -f $KEY -C '' -N '' >&/dev/null; then
exit 1
fi
# sanitize permissions
/usr/bin/chgrp ssh_keys $KEY
/usr/bin/chmod 640 $KEY
/usr/bin/chmod 644 $KEY.pub
Note that the group ssh_keys exists only in RHEL/CentOS/Fedora.
Now that we disable sshd-keygen to allow only cloud-init to create
them, we miss the "sanitize permissions" part, where we set the group
owner as ssh_keys and the private key mode to 640.
According to https://bugzilla.redhat.com/show_bug.cgi?id=2013644#c8, failing
to set group ownership and permissions like openssh does makes the RHEL openscap
tool generate an error.

Allow comments in runcmd and report failed commands correctly
A `runcmd` script may fail to parse properly, but does not mark
`runcmd` as failed when that occurs. Additionally `shellify()` fails
to correctly parse scripts that contain a comment line.
Rectify both issues and add unit tests to verify correct behavior.

The distribution class has a field that specifies the location of
the system hosts file and this can be overridden in subclasses.
While the field is correctly used in distro.update_etc_hosts(), the
update_etc_hosts module does not use it and just assumes '/etc/hosts'
This fixes the module to use the distribution-specific variable.

The current code starts the puppet agent and also sets autostart
in all cases. This conflicts with a common pattern where puppet
itself manages the agent and autostart state.
For example, in my deploy puppet disables the puppet agent
and replaces it with a cron. This causes various races
both within this cloud-init unit and within puppet itself
while cloud-init and puppet fight over whether or not
to enable the service.

- update the puppet module to support AIO installations by setting
`install_type` to `aio`
- make the install collection configurable through the `collection`
parameter; by default the rolling `puppet` collection will be used,
which installs the latest version)
- when `install_type` is `aio`, puppetlabs repos will be purged after
installation; set `cleanup` to `False` to prevent this
- AIO installations are performed by downloading and executing a shell
script; the URL for this script can be overridden using the
`aio_install_url` parameter
- make it possible to run puppet agent after installation/configuration
via the `exec` key
- by default, puppet agent will run with the `--test` argument; this can
be overridden via the `exec_args` key

Implement missing device_aliases feature
The device_aliases key has been documented as part of disk_setup for
years, however the feature was never implemented. This implements the
feature as documented allowing usercfg (rather than dsconfig) to create
a mapping of device names.
This is not to be confused with disk_aliases, a very similar map but
existing solely for use by datasources.

Virtuozzo Linux is a distro based off of CentOS 8, similar to Alma Linux and Rocky Linux.

Also added a new (currently experimental) systemd-networkd renderer,

- Mostly based on FreeBSD, the main exception is that
`find_devs_with_on_freebsd` does not work.
- Since we cannot get the CDROM or the partition labels,
`find_devs_with_on_dragonflybsd()` has a more naive approach and
returns all the block devices.

Rocky Linux is a RHEL-compatible distribution so all changes that have
been made should be trivial.

Presently, mirror keys cannot be associated with primary/security
mirrors. Unfortunately, this prevents use of Landscape-managed
package mirrors as the mirror key for the Landscape-hosted repository
cannot be provided.
This patch allows the same key-related fields usable on "sources"
entries to be used on the "primary" and "security" entries as well.

This reverts commit 74fa008bfcd3263eb691cc0b3f7a055b17569f8b.
During pre-release testing, we discovered two issues with this commit.
Firstly, there's a typo in the udevadm command that causes a TypeError
for _all_ growpart executions. Secondly, the LVM resizing does not
appear to successfully resize everything up to the LV, though some
things do get resized.
We certainly want this change, so we'll be happy to review and land it
alongside an integration test which confirms that it is working as
expected.

git-grep showed a few more locations where we refer to a "user-scripts"
config module which is really cc_scripts_user module. Replace these

This patch adds support to resize a single partition of a VM if it's using an
LVM underneath. The patch detects if it's LVM if the given block device
is a device mapper by its name (e.g. `/dev/dm-1`) and if it has slave
devices under it on sysfs. After that syspath is updated to the real
block device and growpart will be called to resize it (and automatically
its Physical Volume).
The Volume Group will be updated automatically and a final call to
extend the rootfs to the remaining space available will be made.
Using the same growpart configuration, the user can specify only one
device to be resized when using LVM and growpart, otherwise cloud-init
won't know which one should be resized and will fail.

Prior to this commit, when a user specified configuration which would
generate random passwords for users, cloud-init would cause those
passwords to be written to the serial console by emitting them on
stderr. In the default configuration, any stdout or stderr emitted by
cloud-init is also written to `/var/log/cloud-init-output.log`. This
file is world-readable, meaning that those randomly-generated passwords
were available to be read by any user with access to the system. This
presents an obvious security issue.
This commit responds to this issue in two ways:
* We address the direct issue by moving from writing the passwords to
sys.stderr to writing them directly to /dev/console (via
util.multi_log); this means that the passwords will never end up in
cloud-init-output.log
* To avoid future issues like this, we also modify the logging code so
that any files created in a log sink subprocess will only be
owner/group readable and, if it exists, will be owned by the adm
group. This results in `/var/log/cloud-init-output.log` no longer
being world-readable, meaning that if there are other parts of the
codebase that are emitting sensitive data intended for the serial
console, that data is no longer available to all users of the system.

PR #811 added a new config key, emit_keys_to_console, but didn't update the
documentation for mention it.

It is distro dependent whether hostname or fqdn is used

Specifically:
ssh:
emit_keys_to_console: false
We also port the cc_keys_to_console cloud tests to the new integration
testing framework, and add a test for this new option.

The documentation did not mention that the given data may not be the
exact string written: the cloud's random data may be added to it.
Additionally, the documentation of the command key was incorrect.
test_seed_random_data was updated to check that the given data is a
prefix of the written data, to match cloud-init's expected (and, now,
documented) behaviour.

This refactors cc_ca_certs to support non-ca-certificates distros, and
adds RHEL support.
|
|
|
|
Existing config writes keys to /etc/ssh after deleting files matching
a glob that includes certificate files. Since sshd looks for
certificates in the same directory as the keys, a host certificate
must be placed in this directory. This update enables the certificate's
contents to be specified along with the keys.

On FreeBSD, if a UFS has trim: (-t) or MAC multilabel: (-l) flag, resize
FS fail, because the _can_skip_ufs_resize check gets tripped up by the

LP: #1901958
Rather than fixing the parser as in the patches proposed there (and
attempted in #636) this pull-request rips out all of it, and simplifies
the code. We now use `growfs -N` and check if that returns an error. If
it returns the correct kind of error, we can skip the resize, because we
either are at the correct size, or the filesystem in question is broken
or not UFS. If it returns the wrong kind of error, we just re-raise it.

For cc_users_groups the user setting "expiredate" must be quoted in
order for the relevant flag and value to be then passed to the useradd
command. It its vaiue is not quoted then it is treated as Python type
datetime.date and in `cloudinit/distros/__init__.py` the below "is it a
string" condition fails and so no "--expiredate" parameter is passed to
useradd and therefore it has no effect:
```
if key in useradd_opts and val and isinstance(val, str):
useradd_cmd.extend([useradd_opts[key], val])
```
For cc_users_groups, the user setting "inactive" does not actually
disable accounts, the useradd "--inactive" option actually defines the
number of days after password expiry that users can still login. So I
have changed the docs to show it taking a quoted value of days (which
works with the current code) rather than a boolean value. The quotes
are necessary, like expiredate above, so that the value is also passed
to the useradd command.
For cc_power_state_change.py the "delay" setting value needs to have
quotes around it as otherwise its leading plus sign will be stripped
off.

Reliable Scalable Cluster Technology (RSCT) is a set of software
components that together provide a comprehensive clustering
environment(RAS features) for IBM PowerVM based virtual machines. RSCT
includes the Resource Monitoring and Control (RMC) subsystem. RMC is a
generalized framework used for managing, monitoring, and manipulating
resources. RMC runs as a daemon process on individual machines and needs
creation of unique node id and restarts during VM boot.
