2020-02-25Add physical network type: cascading to openstack helpers (#200)sab-systems
* Add physical network type: cascading to openstack helpers * add new helpers test for checking all openstack KNOWN_PHYSICAL_TYPES get type 'physical'.
2020-02-19ec2: Do not log IMDSv2 token values, instead use REDACTED (#219)Ryan Harper
Instead of logging the token values used log the headers and replace the actual values with the string 'REDACTED'. This allows users to examine cloud-init.log and see that the IMDSv2 token header is being used but avoids leaving the value used in the log file itself. LP: #1863943

2019-12-12azure: avoid re-running cloud-init when instance-id is byte-swapped (#84)AOhassan
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.
2019-12-02url_helper: read_file_or_url should pass headers param into readurl (#66)Chad Smith
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. LP: #1854084
2019-11-22ec2: Add support for AWS IMDS v2 (session-oriented) (#55)Ryan Harper
* ec2: Add support for AWS IMDS v2 (session-oriented) AWS now supports a new version of fetching Instance Metadata[1]. Update cloud-init's ec2 utility functions and update ec2 derived datasources accordingly. For DataSourceEc2 (versus ec2-look-alikes) cloud-init will issue the PUT request to obtain an API token for the maximum lifetime and then all subsequent interactions with the IMDS will include the token in the header. If the API token endpoint is unreachable on Ec2 platform, log a warning and fallback to using IMDS v1 and which does not use session tokens when communicating with the Instance metadata service. We handle read errors, typically seen if the IMDS is beyond one etwork hop (IMDSv2 responses have a ttl=1), by setting the api token to a disabled value and then using IMDSv1 paths. To support token-based headers, ec2_utils functions were updated to support custom headers_cb and exception_cb callback functions so Ec2 could store, or refresh API tokens in the event of token becoming stale.

2019-11-20net: IPv6, accept_ra, slaac, stateless (#51)Harald
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
2019-11-13azure: support secondary ipv6 addresses (#33)Chad Smith
Azure's Instance Metadata Service (IMDS) reports multiple IPv6 addresses, via the http://169.254.169.254/metadata/instance/network route. Any additional values after the first in 'ipAddresses' under the 'ipv6' interface key are extracted and configured as static IPs on the interface.
2019-11-13Fix metadata check when local-hostname is null (#32)Mark Goddard
Fix traceback when running with a config drive containing a metadata file which has local-hostname set to null. Cloud-init ignores absent local-hostname or None values. LP: #1852100

2019-11-04azure: support matching dhcp route-metrics for dual-stack ipv4 ipv6Chad Smith
Network v2 configuration for Azure will set both dhcp4 and dhcp6 to False by default. When IPv6 privateIpAddresses are present for an interface in Azure's Instance Metadata Service (IMDS), set dhcp6: True and provide a route-metric value that will match the corresponding dhcp4 route-metric. The route-metric value will increase by 100 for each additional interface present to ensure the primary interface has a route to IMDS. Also fix dhcp route-metric rendering for eni and sysconfig distros. LP: #1850308
2019-11-04configdrive: fix subplatform config-drive for /config-drive sourceDavid Kindred
When ConfigDrive discovers the source path /config-drive, subplatform is now reports 'config-drive' LP: #1849731
2019-10-31DataSourceSmartOS: reconfigure network on each bootMike Gerdts
In typical cases, SmartOS does not use DHCP for network configuration. As such, if the network configuration changes that is reflected in metadata and will be picked up during the next boot. LP: #1765801 Joyent: OS-6902 reconfigure network on each boot
2019-10-31OVF: disable custom script execution by defaultXiaofeng Wang
For security concern, we disable the custom script by default.If a custom script is provided, stop customization unless the custom script is explicitly enabled by tools config.
2019-10-29azure: Do not lock user on instance id changeSam Eiderman
After initial boot ovf-env.xml is copied to agent dir (/var/lib/waagent/) with REDACTED password. On subsequent boots DataSourceAzure loads with a configuration where the user specified in /var/lib/waagent/ovf-env.xml is locked. If instance id changes, cc_users_groups action will lock the user. Fix this behavior by not locking the user if its password is REDACTED. LP: #1849677
2019-10-24exoscale: Increase url_max_wait to 120s.Chris Glass
The exoscale datasource defines a shorter timeout than the default (10) but did not override url_max_wait, resulting in a single attempt being made to wait for the metadata service. In some rare cases, a race condition means the route to the metadata service is not set within 10 seconds, and more attempts should be made. This sets the url_max_wait for the datasource to 120.
2019-10-17guestcust_util: handle special characters in config fileXiaofeng Wang

2019-10-16net: handle openstack dhcpv6-stateless configurationHarald Jensås
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'.

2019-10-11Add Support for e24cloud to Ec2 datasource.Scott Moser
e24cloud provides an EC2 compatible datasource. This just identifies their platform based on dmi 'system-vendor' having 'e24cloud'. https://www.e24cloud.com/en/ . Updated chassis typo in zstack unit test docstring. LP: #1696476

2019-09-27ovf: do not generate random instance-id for IMC customization pathRyan Harper
Cloud-init will not operate properly if the instance-id value changes on each boot. This is the source of a number of behavioral bugs filed against cloud-init with OVF datasource. Instead, use a static instance-id value, iid-vmware-imc, similar to iid-dsovf.

2019-09-18Add datasource for ZStack platform.Shixin Ruan
Zstack platform provides a AWS Ec2 metadata service, and identifies their platform to the guest by setting the 'chassis asset tag' to a string that ends with '.zstack.io'. LP: #1841181
2019-09-11Brightbox: restrict detection to require full domain match .brightbox.comScott Moser
The detection for brightbox in both ds-identify and in identify_brightbox would incorrectly match the domain 'bobrightbox', which is not a brightbox platform. The fix here is to restrict matching to '*.brightbox.com' rather than '*brightbox.com' Also, while here remove a url to bug 1661693 which added the knowledge of brightbox.
2019-09-11VMWware: add option into VMTools config to enable/disable custom script.Xiaofeng Wang
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.
2019-09-09net,Oracle: Add support for netfailover detectionRyan Harper
Add support for detecting netfailover[1] device 3-tuple in networking layer. In the Oracle datasource ensure that if a provided network config, either fallback or provided config includes a netfailover master to remove any MAC address value as this can break under 3-netdev as the other two devices have the same MAC. 1. https://www.kernel.org/doc/html/latest/networking/net_failover.html
2019-08-28Oracle: Render secondary vnic IP and MTU values onlyRyan Harper
When rendering secondary vnic configuration from IMDS, only emit configuration for the IP and MTU values only. Add support to mutate either a v1 or a v2 network_config input.

2019-08-19DataSourceOracle: prefer DS network config over initramfsDaniel Watkins
The Oracle platform provides networking configuration from two sources: * the primary interface configuration comes from the initramfs, because Oracle instance all iSCSI boot * secondary interface configuration comes from an IMDS accessed over HTTP As we need to combine these two sources of network configuration, the default "prefer initramfs config over data source config" behaviour isn't appropriate; we would never get the IMDS interfaces via that route. Instead, the Oracle data source has code to combine these two sources, so we prefer its network configuration over the initramfs configuration. (This is not appropriate default behaviour, because _in general_ data sources won't know how to merge initramfs-provided configuration into their provided configuration, so switching this order for all data sources would result in initramfs configuration being discarded on any data source that implements network_config.)
2019-08-14Azure: Record boot timestamps, system information, and diagnostic eventsAnh Vo
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.
2019-08-14DataSourceOracle: configure secondary NICs on Virtual MachinesDaniel Watkins
Oracle Cloud Infrastructure's Instance Metadata Service provides network configuration information for non-primary NICs. This commit introduces support, on Virtual Machines[0], for fetching that network metadata, converting it to v1 network-config[1] and combining it into the network configuration generated for the primary interface. By default, this behaviour is not enabled. Configuring the Oracle datasource to `configure_secondary_nics` enables it: datasource: Oracle: configure_secondary_nics: true Failures to fetch and generate secondary NIC configuration will log a warning, but otherwise will not affect boot. [0] The expected use of the IMDS-provided network configuration is substantially different on Bare Metal Machines, so support for that will be addressed separately. [1] This is v1 config, because cloudinit.net.cmdline generates v1 config and we need to integrate the secondary NICs into that configuration.
2019-08-13azure/net: generate_fallback_nic emits network v2 config instead of v1Chad Smith
The function generate_fallback_config is used by Azure by default when not consuming IMDS configuration data. This function is also used by any datasource which does not implement it's own network config. This simple fallback configuration sets up dhcp on the most likely NIC. It will now emit network v2 instead of network v1. This is a step toward moving all components talking in v2 and allows us to avoid costly conversions between v1 and v2 for newer distributions which rely on netplan.
2019-08-09Add support for publishing host keys to GCE guest attributesRick Wright
This adds an empty publish_host_keys() method to the default datasource that is called by cc_ssh.py. This feature can be controlled by the 'ssh_publish_hostkeys' config option. It is enabled by default but can be disabled by setting 'enabled' to false. Also, a blacklist of key types is supported. In addition, this change implements ssh_publish_hostkeys() for the GCE datasource, attempting to write the hostkeys to the instance's guest attributes. Using these hostkeys for ssh connections is currently supported by the alpha version of Google's 'gcloud' command-line tool. (On Google Compute Engine, this feature will be enabled by setting the 'enable-guest-attributes' metadata key to 'true' for the project/instance that you would like to use this feature for. When connecting to the instance for the first time using 'gcloud compute ssh' the hostkeys will be read from the guest attributes for the instance and written to the user's local known_hosts file for Google Compute Engine instances.)

2019-07-26net/cmdline: split interfaces_by_mac and init network config determinationDaniel Watkins
Previously "cmdline" network configuration could be either user-specified network-config=... configuration data, or initramfs-provided configuration data. Before data sources could modify the order in which network config sources were considered, this conflation didn't matter (and, indeed, in the default data source configuration it will continue to not matter). However, it _is_ desirable for a data source to be able to specify that its network configuration should be preferred over the initramfs-provided network configuration but still allow explicit network-config=... configuration passed to the kernel cmdline to continue to override both of those sources. (This also modifies the Oracle data source to use read_initramfs_config directly, which is effectively what it was using read_kernel_cmdline_config for previously.)
2019-07-23stages: allow data sources to override network config source orderDaniel Watkins
Currently, if a platform provides any network configuration via the "cmdline" method (i.e. network-data=... on the kernel command line, ip=... on the kernel command line, or iBFT config via /run/net-*.conf), the value of the data source's network_config property is completely ignored. This means that on platforms that use iSCSI boot (such as Oracle Compute Infrastructure), there is no way for the data source to configure any network interfaces other than those that have already been configured by the initramfs. This change allows data sources to specify the order in which network configuration sources are considered. Data sources that opt to use this mechanism will be expected to consume the command line network data and integrate it themselves. (The generic merging of network configuration sources was considered, but we concluded that the single use case we have presently (a) didn't warrant the increased complexity, and (b) didn't give us a broad enough view to be sure that our generic implementation would be sufficiently generic. This change in no way precludes a merging strategy in future.)
2019-07-16VMWare: Trigger the post customization script via cc_scripts module.Xiaofeng Wang
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. LP: #1833192
2019-07-10Fix a couple of issues raised by a coverity scanDaniel Watkins
* cc_lxd: fix copy/paste error in debug logging * DataSourceCloudSigma: remove unreachable code * This unreachable code was introduced in a refactor (in 2015) which removed the need for an exception handler, but retained the logging from the exception handler as an unreachable fall-through.

blkid is a Linux-only command. With this patch, cloud-init uses another approach to find the data source on FreeBSD. LP: #1645824
2019-05-10Azure: Return static fallback address as if failed to find endpointJason Zions (MSFT)
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.
