* FreeBSD: add ResizeGrowFS class to cc_growpart (#2334)Mina Galić2023-05-161-6/+29
| | | | | | | | | this FreeBSD specific resizer resizes the root partition and grows the Filesystem all in one. All we have to do is call ``service growfs onestart`` Document behaviour: especially that growfs will insert a swap partition if none is present, unless instructed otherwise.

* schema: read_cfg_paths call init.fetch to lookup /v/l/c/instanceChad Smith2023-05-123-1/+36
| | | | | | | | | | | | | | | | | | Fix cloud-init schema --system being unable to find merged userdata stored at /var/lib/cloud/instance/cloud_config.txt. Init.paths.get_ipath only has visibility to merged cloud config in /var/lib/cloud/<instance_id>/cloud-config.txt after fetching the existing cached datasource which provides instance-id from metadata in order to determine the unique instance-id which represents the path to the cloud-config.txt. To support reuse of read_cfg_paths helper function, add an optional parameter fetch_existing_datasource which indicates whether reading the existing datasource is necessary for this helper function. cloud-init schema --system calls read_cfg_paths providing fetch_existing_datasource="trust" prior to calls to paths.get_ipath().
* azure/errors: introduce reportable errors for imds (#3647)Chris Patterson2023-05-122-1/+129
| | | | | | | | | | | | | | | Always report failure to host, but report failure to fabric only outside of _check_if_nic_is_primary() which is expected to fail if nic is not primary. Add two types of reportable errors for IMDS metadata: - add ReportableErrorImdsUrlError() for url errors. - add ReportableErrorImdsMetadataParsingException() for parsing errors. Tweak ReportableError repr to be a bit friendlier. Signed-off-by: Chris Patterson <cpatterson@microsoft.com>
* azure/errors: add host reporting for dhcp errors (#2167)Chris Patterson2023-05-112-11/+76
| | | | | | | | | | | | | | | | | | | | | | | - Add host_only flag to _report_failure() to allow caller to only report the failure to host. This is for cases where we don't want _report_failure() to attempt DHCP or we expect that we may recover from the reported error (there is no issue reporting multiple times to host, whereas fabric reports will immediately fail the VM provisioning). - Add ReportableErrorDhcpLease() to report lease failures. - Add ReportableErrorDhcpInterfaceNotFound() to report errors where the DHCP interface hasn't been found yet. - Add TestReportFailure class with new test coverage. Will migrate other _report_failure() tests in the future as they currently depend on TestAzureDataSource/CiTestCase. Future work will add the interface name to supporting data, but as that information is not available with iface=None, another PR will explicitly add a call to net.find_fallback_nic() to specify it.

* cli: schema validation of jinja template user-data (SC-1385) (#2132)Chad Smith2023-04-281-33/+160
| | | | | | | | | | | The CLI cloud-init schema now asserts that the leading header comment in user-data files is a valid user-data type. Raise an informative error otherwise about valid user-data types. For user-data files declared with '## template: jinja', render those files first sourcing jinja variables from /run/cloud-init/instance-data.json or a new --instance-data parameter. Once the jinja template is rendered, validate schema of the resulting #cloud-config user-data. This branch also ensures any errors and deprecation warnings are unique. LP: #1881925

Also, modify the permissions of cloud-init.log to be 640, so that sensitive data leaked to the log isn't world readable. Additionally, remove the logging of user data and vendor data to cloud-init.log from the Vultr datasource. LP: #2013967 CVE: CVE-2023-1786
* sources/azure: report failures to host via kvp (#2136)Chris Patterson2023-04-252-0/+48
| | | | | | | | | | | | | | Azure can report provisioning failures via the Wireserver health endpoint. However, in the event of networking failures or Wireserver issues, this report cannot be made and the VM will result in an OS provisioning timeout and a generic error is presented to the user. Report the failure via KVP using the "PROVISIONING_REPORT" key so that the host can relay the provisioning error report to the user when the VM fails to provision. The format used is subject to change and/or removal. Signed-off-by: Chris Patterson <cpatterson@microsoft.com>

* azure/imds: retry fetching metadata up to 300 seconds (#2121)Chris Patterson2023-04-192-67/+124
| | | | | | | | | | | | | | Instead of a fixed number of retries, allow up to 5 minutes to fetch metadata from IMDS. The current approach allows for up to 11 attempts depending on the path. Given the timeout setting, this can vary from ~11 seconds up to ~32 seconds depending on whether or not read/connection timeouts are encountered. Delaying boot on the rare occasion that IMDS is delayed is better than ignoring the metadata as it ensures the VM is configured as expected. This is a very conservative timeout and may be reduced in the future. Signed-off-by: Chris Patterson <cpatterson@microsoft.com>
* [1/2] DHCP: Refactor dhcp client code (#2122)Brett Holman2023-04-1916-101/+169
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move isc-dhclient code to dhcp.py In support of the upcoming deprecation of isc-dhcp-client, this code refactors current dhcp code into classes in dhcp.py. The primary user-visible change should be the addition of the following log: dhcp.py[DEBUG]: DHCP client selected: dhclient This code lays groundwork to enable alternate implementations to live side by side in the codebase to be selected with distro-defined priority fallback. Note that maybe_perform_dhcp_discovery() now selects which dhcp client to call, and then runs the corresponding client's dhcp_discovery() method. Currently only class IscDhclient is implemented, however a yet-to-be-implemented class Dhcpcd exists to test fallback behavior and this will be implemented in part two of this series. Part of this refactor includes shifting dhclient service management from hardcoded calls to the distro-defined manage_service() method in the *BSDs. Future work is required in this area to support multiple clients via select_dhcp_client().

* azure/errors: introduce reportable errors (#2129)Chris Patterson2023-04-193-26/+169
| | | | | | | | | | | | | | | When provisioning failures occur an Azure, a generic description is used in the report and ultimately returned to the user. To improve the user experience, report details of the failure in a manner that is parsable, readable and succinct. The current approach is to use csv with a custom delimiter ("|") and quote character ("'"). This format may change in the future. Gracefully handle reportable errors thrown while crawling metadata and treat other exceptions as ReportableErrorUnhandledException. Future work will introduce more reportable errors to handle the expected failure cases. Signed-off-by: Chris Patterson <cpatterson@microsoft.com>
* users: schema permit empty list to indicate create no usersChad Smith2023-04-172-27/+31
| | | | | | | | When defining json schema in a63f45f7, we were a bit too strict by setting `minItems: 1` on the `users:` list. This schema definition regressed the ability to prevent default_user creation with user-data. Remove that schema constraint because the code already supports this case.

* NoCloud: Use seedfrom protocol to determine mode (#2107)Brett Holman2023-04-121-1/+4
| | | | | | | | Historically ds=nocloud-net was a required argument for the user to pass in to tell cloud-init which mode to use. This argument, however, is redundant when a seedfrom argument is passed. Allow the mode to be automatically determined, so that the user need not pass a mode configuration to achieve desired behavior.

* Adapt DataSourceScaleway to upcoming IPv6 support (#2033)Louis Bouchard2023-04-051-119/+554
| | | | | | | | | | | | | | | | | | | Add support for IPv4 and/or IPv6 provided metadata. Upcoming features will allow for Instances to be started with only IPv6 connectivity. The datasource must be able to fetch its metadata from the following endpoints : * IPv4 on http://169.264.42.42/conf * IPv6 on http://[fd00:42::42]/conf This URL may eventually be overridden in the future by a DNS resolvable URL defined in /etc/cloud/config.d/scaleway.conf Add support for the configuration of one or many IP addresses when provided by the `public_ips` metadata key. In such configurations, instances no longer have a `private_ip`. The previous configuration method is kept for backward compatibility. This commit also fixes a bug in the definition of ssh keys from tags.

Drop several impacted tests as coverage already exists in TestProvisioning, and update the rest to handle the +/- 1 DHCP attempt due to varying assumptions around PPS state and DHCP.
* schema: do not manipulate draft4 metaschema for jsonschema 2.6.0 (#2098)Chad Smith2023-03-292-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only set additionalProperties = False on draft4 schema definition in jsonschema 3.0 or greater because cloud-init globally registers its draft4 extensions as the primary validator for any draft4-based schemas in the same python process. This affects solutions such as subiquity and ubuntu-desktop-installer which invoke jsonschema.validate in the same process at runtime just after calling cloudinit.schema.get_jsonschema_validator. The resulting Tracebacks are seen as something like: jsonschema.exceptions.SchemaError: {'$ref': '#/definitions/ref_id'} is not valid under any of the given schema Background: cloud-init needs to extend draft4 schema to better validate and warn 'deprecated' properties in draft4-based cloud-init schema definitions. Our unittests also attempt to strictly validate any meta schema definitions for the cc_* config modules. To accomplish strict meta schema validation cloud-init makes a copy of the draft4 meta schema and adds an 'additionalProperties' = True to that schema to raise specific errors and catch typos in cc_ module schema definitions. Given that cloud-init at runtime extends and registers a draft4 schema validator, any external consumers of jsonschema.validate with draft4-base schemas are exposed to cloud-init's validator so let's limit our risk exposure. For python 2.6.0, we cannot specify make draft4 schema strict because any "$ref" keys are not yet resolved to their actual #/defintions/<id> values so the traceback above will always be generated in 'strict' mode for complex schemas. This does not affect jsonschema 3.0+ which appears to resolve schema $refs values before schema validation.
* sources/azure/imds: don't count timeout errors as connection errors (#2074)Chris Patterson2023-03-292-3/+2
| | | | | | | | | | | | | | | When fetching metadata in _check_if_nic_is_primary() the retry count is 300, but fails out after 10 connection errors. In some cases, fetching from IMDS may fail with read timeout for more than 10 attempts, far sooner than the desired 300. Keeping the existing max_connection_errors = 10 is fine so long as it is truly a connection error. These generally shouldn't occur when using the primary NIC. Always retry on timeout errors (up until desired limit) and count only connections errors against max_connection_errors. Signed-off-by: Chris Patterson <cpatterson@microsoft.com>
