2021-10-07Allow disabling of network activation (SC-307) (#1048)James Falcon
In #919 (81299de), we refactored some of the code used to bring up networks across distros. Previously, the call to bring up network interfaces during 'init' stage unintentionally resulted in a no-op such that network interfaces were NEVER brought up by cloud-init, even if new network interfaces were found after crawling the metadata. The code was altered to bring up these discovered network interfaces. On ubuntu, this results in a 'netplan apply' call during 'init' stage for any ubuntu-based distro on a datasource that has a NETWORK dependency. On GCE, this additional 'netplan apply' conflicts with the google-guest-agent service, resulting in an instance that can no be connected to. This commit adds a 'disable_network_activation' option that can be enabled in /etc/cloud.cfg to disable the activation of network interfaces in 'init' stage. LP: #1938299
2021-10-07renderer: convert relative imports to absolute (#1052)Paride Legovini
Fixes the following pylint error: cloudinit/net/renderer.py:12: [E0611(no-name-in-module), ] No name 'generate_udev_rule' in module 'udev' Likely a false positive, but we don't really need to keep the imports relative, so let's convert them to absolute as a workaround.
2021-10-07Support ETHx_IP6_GATEWAY, SET_HOSTNAME on OpenNebula (#1045)Vlastimil Holer
OpenNebula 6.1.80 (current dev. version) is introducing new IPv6 gateway contextualization variable ETHx_IP6_GATEWAY, which mimics existing variable ETHx_GATEWAY6. The ETHx_GATEWAY6 used until now will be depracated in future relase (ET spring 2022). See: - new variable - https://github.com/OpenNebula/one/commit/e4d2cc11b9f3c6d01b53774b831f48d9d089c1cc - deprecation tracking issue - https://github.com/OpenNebula/one/issues/5536 Also, added support for SET_HOSTNAME context variable, which is currently widely used variable to configure guest VM hostname.

2021-09-20Add retries to DataSourceGCE.py when connecting to GCE (#1005)vteratipally
Add retries to DatasourceGCE when connecting to GCE. Sometimes when the trying to fetch the metadata, cloud-init fails and the fallback datasource NoCloud is used which is not expected. Add retries to ensure loading of the data source.
2021-09-17Set Azure to apply networking config every BOOT (#1023)James Falcon
In #1006, we set Azure to apply networking config every BOOT_NEW_INSTANCE because the BOOT_LEGACY option was causing problems applying networking the second time per boot. However, BOOT_NEW_INSTANCE is also wrong as Azure needs to apply networking once per boot, during init-local phase.
2021-09-17Add connectivity_url to Oracle's EphemeralDHCPv4 (#988)James Falcon
Add connectivity_url to Oracle's EphemeralDHCPv4 On bionic, when trying to bring up the EphemeralDHCPv4, it's possible that we already have a route defined, which will result in an error when trying to add the DHCP route. Use the connectivity_url to check if we can reach the metadata service, and if so, skip the EphemeralDHCPv4. The has_url_connectivity function has also been modified to take a dict of kwargs to send to readurl. LP: #1939603

2021-09-07ssh_utils.py: ignore when sshd_config options are not key/value pairs (#1007)Emanuele Giuseppe Esposito
As specified in #LP 1845552, In cloudinit/ssh_util.py, in parse_ssh_config_lines(), we attempt to parse each line of sshd_config. This function expects each line to be one of the following forms: \# comment key value key=value However, options like DenyGroups and DenyUsers are specified to *optionally* accepts values in sshd_config. Cloud-init should comply to this and skip the option if a value is not provided. Signed-off-by: Emanuele Giuseppe Esposito <eesposit@redhat.com>
2021-09-03Set Azure to only update metadata on BOOT_NEW_INSTANCE (#1006)James Falcon
In #834, we refactored the handling of events for fetching new metadata. Previously, in Azure's __init__, the BOOT event was added to the update_events, so it was assumed that Azure required the standard BOOT behavior, which is to apply metadata twice every boot: once during local-init, then again during standard init phase. https://github.com/canonical/cloud-init/blob/21.2/cloudinit/sources/DataSourceAzure.py#L356 However, this line was effectively meaningless. After the metadata was fetched in local-init, it was then pickled out to disk. Because "update_events" was a class variable, the EventType.BOOT was not persisted into the pickle. When the pickle was then unpickled in the init phase, metadata did not get re-fetched because EventType.BOOT was not present, so Azure is effectely only BOOT_NEW_INSTANCE. Fetching metadata twice during boot causes some issue for pre-provisioning on Azure because updating metadata during re-provisioning will cause cloud-init to poll for reprovisiondata again in DataSourceAzure, which will infinitely return 404(reprovisiondata is deleted from IMDS after health signal was sent by cloud-init during init-local). This makes cloud-init stuck in 'init'
2021-09-02cc_update_etc_hosts: Use the distribution-defined path for the hosts file (#983)Andy Fiddaman
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.

2021-09-01puppet config: add the start_agent option (#1002)Andrew Bogott
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.
2021-09-01Fix `make style-check` errors (#1000)Shreenidhi Shedi
Using flake8 inplace of pyflakes Renamed run-pyflakes -> run-flake8 Changed target name to flake8 in Makefile With pyflakes we can't suppress warnings/errors in few required places. flake8 is flexible in that regard. Hence using flake8 seems to be a better choice here. flake8 does the job of pep8 anyway. So, removed pep8 target from Makefile along with tools/run-pep8 script. Included setup.py in flake8 checks

2021-08-24Azure: Retry dhcp on timeouts when polling reprovisiondata (#998)aswinrajamannar
In the nic attach path, we skip doing dhcp since we already did it when bringing the interface up. However when polling for reprovisiondata, it is possible for the request to timeout due to platform issues. In those cases we still need to do dhcp and try again since we tear down the context. We can only skip the first dhcp attempt.

2021-08-12Azure: Check if interface is up after sleep when trying to bring it up (#972)aswinrajamannar
When bringing interface up by unbinding and then binding hv_netvsc driver, it might take a short delay after binding for the link to be up. So before trying unbind/bind again after sleep, check if the link is up. This is a corner case when a preprovisioned VM is reused and the NICs are hot-attached.

2021-08-10Update inconsistent indentation (#962)Andrew Kutz
This patch updates some indentation in a comment that prevented an attempt to run the Black formatter (https://github.com/psf/black) against the cloud-init codebase: $ find cloudinit -name '*.py' -type f | xargs black -l 79 --check ... Oh no! 💥 💔 💥 262 files would be reformatted, 19 files would be left unchanged, 1 file would fail to reformat. The one file that fails to format is cloudinit/net/__init__.py. With this fix in place, the black command can successfully parse the file into AST and back again: $ black -l 79 --check cloudinit/net/__init__.py would reformat cloudinit/net/__init__.py Oh no! 💥 💔 💥 1 file would be reformatted. Normally this patch would be part of such an overall effort, but since this is the only location that interrupted running the black command, this author felt it was worth addressing this discrepancy sooner than later in the case there is subsequent desire to use a standard format tool such as black.
2021-08-10cc_puppet: support AIO installations and more (#960)Gabriel Nagy
- 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
2021-08-09Datasource for VMware (#953)Andrew Kutz
This patch finally introduces the Cloud-Init Datasource for VMware GuestInfo as a part of cloud-init proper. This datasource has existed since 2018, and rapidly became the de facto datasource for developers working with Packer, Terraform, for projects like kube-image-builder, and the de jure datasource for Photon OS. The major change to the datasource from its previous incarnation is the name. Now named DatasourceVMware, this new version of the datasource will allow multiple transport types in addition to GuestInfo keys. This datasource includes several unique features developed to address real-world situations: * Support for reading any key (metadata, userdata, vendordata) both from the guestinfo table when running on a VM in vSphere as well as from an environment variable when running inside of a container, useful for rapid dev/test. * Allows booting with DHCP while still providing full participation in Cloud-Init instance data and Jinja queries. The netifaces library provides the ability to inspect the network after it is online, and the runtime network configuration is then merged into the existing metadata and persisted to disk. * Advertises the local_ipv4 and local_ipv6 addresses via guestinfo as well. This is useful as Guest Tools is not always able to identify what would be considered the local address. The primary author and current steward of this datasource spoke at Cloud-Init Con 2020 where there was interest in contributing this datasource to the Cloud-Init codebase. The datasource currently lives in its own GitHub repository at https://github.com/vmware/cloud-init-vmware-guestinfo. Once the datasource is merged into Cloud-Init, the old repository will be deprecated.

2021-08-09Stop copying ssh system keys and check folder permissions (#956)Emanuele Giuseppe Esposito
In /etc/ssh/sshd_config, it is possible to define a custom authorized_keys file that will contain the keys allowed to access the machine via the AuthorizedKeysFile option. Cloudinit is able to add user-specific keys to the existing ones, but we need to be careful on which of the authorized_keys files listed to pick. Chosing a file that is shared by all user will cause security issues, because the owner of that key can then access also other users. We therefore pick an authorized_keys file only if it satisfies the following conditions: 1. it is not a "global" file, ie it must be defined in AuthorizedKeysFile with %u, %h or be in /home/<user>. This avoids security issues. 2. it must comply with ssh permission requirements, otherwise the ssh agent won't use that file. If it doesn't meet either of those conditions, write to ~/.ssh/authorized_keys We also need to consider the case when the chosen authorized_keys file does not exist. In this case, the existing behavior of cloud-init is to create the new file. We therefore need to be sure that the file complies with ssh permissions too, by setting: - the actual file to permission 600, and owned by the user - the directories in the path that do not exist must be root owned and with permission 755.
2021-08-05generate contents for ovf-env.xml when provisioning via IMDS (#959)Anh Vo
Azure Linux Agent (WaLinuxAgent) waits for the ovf-env.xml file to be written by cloud-init when cloud-init provisions the VM. This file is written whenever cloud-init reads its contents from the provisioning ISO. With this change, when there is no provisioning ISO, DataSourceAzure will generate the ovf-env.xml file based on the metadata obtained from Azure IMDS.

2021-08-03Implementing device_aliases as described in docs (#945)Mal Graty
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. LP: #1867532
2021-07-23Add ability to manage fallback network config on PhotonOS (#941)sshedi
Currently cloud-init generates fallback network config on various scenarios. For example: 1. When no DS found 2. There is no 'network' info given in DS metadata. 3. If a DS gives a network config once and upon reboot if DS doesn't give any network info, previously set network data will be overridden. A newly introduced key in cloud.cfg.tmpl can be used to control this behavior on PhotonOS. Also, if OS comes with a set of default network files(configs), like in PhotonOS, cloud-init should not overwrite them by default. This change also includes some nitpicking changes of reorganizing few config variables. Signed-off-by: Shreenidhi Shedi <sshedi@vmware.com>

2021-07-20Update pylint to v2.9.3 and fix the new issues it spots (#946)Paride Legovini
In CI run against pylint 2.9.3 and fix occurrences of: - W0237 (arguments-renamed) - W0402 (deprecated-module) The W0402 deprecated-module was about module `imp`: cloudinit/patcher.py:9: [W0402(deprecated-module), ] Uses of a deprecated module 'imp' The imp module is deprecated and replaced by importlib, which according to the documentation has no replacement for acquire_lock() and release_lock(), which are the only reason why `imp` is imported. Nothing about the code using this lock that actually requires it. Let's remove the locking code and the import altogether. Dropping the locking makes patcher.patch() an empty wrapper around _patch_logging(). Rename _patch_logging() to patch_logging() and call it directly instead. Drop patch().
2021-07-19Azure: mount default provisioning iso before try device listing (#870)Anh Vo
With a few exceptions, Azure VM deployments receive provisioning metadata through the provisioning iso presented as a cdrom device (/dev/sr0). The existing code attempts to find this device by calling blkid to find all devices that have either type iso9660 or udf. This can be very expensive if the VM has a lot of disks. This commit will attempt to mount the default iso location first and only tries to use blkid to locate the iso location if the default mounting location fails
2021-07-19Initial hotplug support (#936)James Falcon
Adds a udev script which will invoke a hotplug hook script on all net add events. The script will write some udev arguments to a systemd FIFO socket (to ensure we have only instance of cloud-init running at a time), which is then read by a new service that calls a new 'cloud-init devel hotplug-hook' command to handle the new event. This hotplug-hook command will: - Fetch the pickled datsource - Verify that the hotplug event is supported/enabled - Update the metadata for the datasource - Ensure the hotplugged device exists within the datasource - Apply the config change on the datasource metadata - Bring up the new interface (or apply global network configuration) - Save the updated metadata back to the pickle cache Also scattered in some unrelated typing where helpful
2021-07-15Fix MIME policy failure on python version upgrade (#934)James Falcon
Python 3.6 added a new `policy` attribute to `MIMEMultipart`. MIMEMultipart may be part of the cached object pickle of a datasource. Upgrading from an old version of python to 3.6+ will cause the datasource to be invalid after pickle load. This commit uses the upgrade framework to attempt to access the mime message and fail early (thus discarding the cache) if we cannot. Commit 78e89b03 should fix this issue more generally.
2021-07-12ssh-util: allow cloudinit to merge all ssh keys into a custom user file, ↵Emanuele Giuseppe Esposito
defined in AuthorizedKeysFile (#937) This patch aims to fix LP1911680, by analyzing the files provided in sshd_config and merge all keys into an user-specific file. Also introduces additional tests to cover this specific case. The file is picked by analyzing the path given in AuthorizedKeysFile. If it points inside the current user folder (path is /home/user/*), it means it is an user-specific file, so we can copy all user-keys there. If it contains a %u or %h, it means that there will be a specific authorized_keys file for each user, so we can copy all user-keys there. If no path points to an user-specific file, for example when only /etc/ssh/authorized_keys is given, default to ~/.ssh/authorized_keys. Note that if there are more than a single user-specific file, the last one will be picked.
