2019-05-24freebsd: NoCloud data source supportGonéri Le Bouder
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.
2019-05-09release 19.1Chad Smith
Bump the version on cloudinit/version.py to be 19.1 and update ChangeLog LP: #1828479
2019-05-08cc_mounts: check if mount -a on no-change fstab pathJason Zions (MSFT)
Under some circumstances, cc_disk_setup may reformat volumes which already appear in /etc/fstab (e.g. Azure ephemeral drive is reformatted from NTFS to ext4 after service-heal). Normally, cc_mounts only calls mount -a if it altered /etc/fstab. With this change cc_mounts will read /proc/mounts and verify if configured mounts are already mounted and if not raise flag to request a mount -a. This handles the case where no changes to fstab occur but a mount -a is required due to change in underlying device which prevented the .mount unit from running until after disk was reformatted.

2019-05-08DataSourceAzure: Adjust timeout for polling IMDSAnh Vo
If the IMDS primary server is not available, falling back to the secondary server takes about 1s. The net result is that the expected E2E time is slightly more than 1s. This change increases the timeout to 2s to prevent the infinite loop of timeouts.
2019-04-29Azure: Changes to the Hyper-V KVP ReporterAnh Vo
 + Truncate KVP Pool file to prevent stale entries from being processed by the Hyper-V KVP reporter.  + Drop filtering of KVPs as it is no longer needed.  + Batch appending of existing KVP entries.
2019-04-27git tests: no longer show warning about safe yaml.Scott Moser
Currently on 18.04, running tox -e py27 will spew errors like: .tests/unittests/test_net.py:2649: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details. The change here just uses cloud-init's yaml, which does safeloading by default.
2019-04-22net/sysconfig: only indicate available on known sysconfig distrosRyan Harper
Restrict the sysconfig renderer availabily to known distros. Ubuntu/Debian systems may include network-manager but they do not have support for reading sysconfig network output; that is enabled via a Network-Manager plugin: ifcfg-rh which is not available in Ubuntu/Debian. LP: #1819994
2019-04-18mount_cb: do not pass sync and rw options to mountGonéri Le Bouder
On FreeBSD, mount_cd9660 does not accept the sync option that is enabled by default. In addition, the sync is only useful with the `rw` mode. However the `rw` mode was never used. This patch removes the `rw` and `sync` parameter of `mount_cb` to simplify the code base and resolve the FreeBSD issue. LP: #1645824

2019-04-10Revert "DataSource: move update_events from a class to an instance..."Daniel Watkins
Moving update_events from a class attribute to an instance attribute means that it doesn't exist on DataSource objects that are unpickled, causing tracebacks on cloud-init upgrade. As this change is only required for cloud-init installations which don't utilise ds-identify, we're backing it out to be reintroduced once the upgrade path bug has been addressed. This reverts commit f2fd6eac4407e60d0e98826ab03847dda4cde138.
2019-04-09Change DataSourceNoCloud to ignore file system label's case.Risto Oikarinen
NoCloud data source now accepts both 'cidata' and 'CIDATA' as filesystem labels. This is similar to DataSourceConfigDrive's support for 'config-2' and 'CONFIG-2'.
2019-04-09cmd:main.py: Fix missing 'modules-init' key in modes dictAntonio Romito
Cloud-init's main.py will fail when presented with a new stage name 'modules-init' if upgrading an older cloud-init. Fix this by initializing unknown stage names before accessing. LP: #1815109
2019-04-04ubuntu_advantage: rewrite cloud-config moduleChad Smith
ubuntu-advantage-tools version 19 has a different command line interface. Update cloud-init's config module to accept new ubuntu_advantage configuration settings. * Underscores better than hyphens: deprecate 'ubuntu-advantage'   cloud-config key in favor of 'ubuntu_advantage' * Attach machines with either sso credentials of UA user_token * Services are enabled by name though an 'enable' list * Raise warnings if deprecated ubuntu-advantage config keys are   present, or errors if its config we cannott adapt to Ubuntu Advantage support can now be configured via #cloud-config with the following yaml: ubuntu_advantage:   token: 'thisismyubuntuadvantagetoken'   enable: [esm, fips, livepatch] Co-Authored-By: Daniel Watkins <daniel.watkins@canonical.com>
2019-04-03Azure: Treat _unset network configuration as if it were absentJason Zions (MSFT)
When the Azure datasource persists all of its metadata to the instance directory, it deliberately sets the self.network_config value to be the sources.UNSET value. The goal is to ensure that each time the system boots, fresh network configuration data is fetched from the cloud platform so that any control plane changes will take effect. When a VM is first created, there's no pickled instance to restore, so self._network_config is None, resulting in self.network_config() properly building a new config. Azure suffered from LP: #1801364 which prevented ds from being stored in obj.pkl in the instance directory, so subsequent reboots always regenerated their network configuration. Commit 0dc3a77f41f4544e4cb5a41637af7693410d4cdf introduced a new bug in which self.network_config() assumed the self._network_config value was either None or trustable; when the config was unpickled, that value was _unset, thus breaking the assumption. LP: #1823084
2019-04-03DatasourceAzure: add additional logging for azure datasourceAnh Vo
Create an Azure logging decorator and use additional ReportEventStack context managers to provide additional logging details.
2019-03-26Azure: Ensure platform random_seed is always serializable as JSON.Jason Zions (MSFT)
The Azure platform surfaces random bytes into /sys via Hyper-V. Python 2.7 json.dump() raises an exception if asked to convert a str with non-character content, and python 3.0 json.dump() won't serialize a "bytes" value. As a result, c-i instance data is often not written by Azure, making reboots slower (c-i has to repeat work). The random data is base64-encoded and then decoded into a string (str or unicode depending on the version of Python in use). The base64 string has just as many bits of entropy, so we're not throwing away useful "information", but we can be certain json.dump() will correctly serialize the bits.
2019-03-25net/sysconfig: write out SUSE-compatible IPv6 configRobert Schweikert
For writing IPv6 addresses to ifcfg-* the name "IPV6ADDR" is used. For secondary IPs the value for "IPV6ADDR_SECONDARIES" is set. On SUSE based distributions the names "IPADDR6" and "IPADDR6_$SOMELABEL" need to be used.
2019-03-21net: Fix ipv6 static routes when using eni rendererRaphael Glon
When rendering ipv6 static routes in eni format the post-up/pre down commands were not correct for ipv6. LP: #1818669
2019-03-19Add ubuntu_drivers config moduleDaniel Watkins
The ubuntu_drivers config module enables usage of the 'ubuntu-drivers' command. At this point it only serves as a way of installing NVIDIA drivers for general purpose graphics processing unit (GPGPU) functionality. Also, a small usability improvement to get_cfg_by_path to allow it to take a string for the key path "toplevel/second/mykey" in addition to the original: ("toplevel", "second", "mykey")
2019-03-14DataSource: move update_events from a class to an instance attributeDaniel Watkins
Currently, DataSourceAzure updates self.update_events in __init__. As update_events is a class attribute on DataSource, this updates it for all instances of classes derived from DataSource including those for other clouds. This means that if DataSourceAzure is even instantiated, its behaviour is applied to whichever data source ends up being used for boot. To address this, update_events is moved from a class attribute to an instance attribute (that is therefore populated at instantiation time). This retains the defaults for all DataSource sub-class instances, but avoids them being able to mutate the state in instances of other DataSource sub-classes. update_events is only ever referenced on an instance of DataSource (or a sub-class); no code relies on it being a class attribute. (In fact, it's only used within methods on DataSource or its sub-classes, so it doesn't even _need_ to remain public, though I think it's appropriate for it to be public.) DataSourceScaleway is also updated to move update_events from a class attribute to an instance attribute, as the class attribute would now be masked by the DataSource instance attribute. LP: #1819913
2019-03-12net/sysconfig: Handle default route setup for dhcp configured NICsRobert Schweikert
When the network configuration has a default route configured and another network device that is configured with dhcp, SUSE sysconfig output should not accept the default route provided by the dhcp server. LP: #1812117
2019-03-12DataSourceEc2: update RELEASE_BLOCKER to be more accurateDaniel Watkins
Our previous understanding of the upgrade issue was incomplete; it turns out the only change we need is the one now outlined.
2019-03-06Support locking user with usermod if passwd is not available.Scott Moser
In some cases, the 'passwd' command might not be available, but 'usermod' might be. In debian systems both are provided by the 'passwd' package. In Redhat/Centos passwd comes from 'passwd' package while 'usermod' comes from `shadow-utils` This should just support either one with no real cost other than the check.
2019-03-04clean: correctly determine the path for excluding seed directoryDaniel Watkins
Previously, init.paths.cloud_dir has a trailing slash, which meant that "/var/lib/cloud//seed" was being compared to "/var/lib/cloud/seed" and (of course), never matching. In this commit, switch to using os.path.join to avoid this case (and update the tests to catch it in future). LP: #1818571
2019-03-04helpers/openstack: Treat unknown link types as physicalDaniel Watkins
Some deployments of OpenStack expose link types to the guest which cloud-init doesn't recognise. These will almost always be physical, so we can operate more robustly if we assume that they are (whilst warning the user that we're seeing something unexpected). LP: #1639263
2019-03-04drop Python 2.6 support and our NIH version detectionDaniel Watkins
- Remove the last few places that use `if PY26` - Replace our Python version detection logic with six's (which we were already using in most places)
2019-03-04net: append type:dhcp[46] only if dhcp[46] is True in v2 netconfigKurt Stieger
When providing netplan configuration to cloud-init, the internal network state would enable DHCP if the 'dhcp' key was present in the source config. In netplan, dhcp[46] is a boolean and the value of the boolean should control whether DHCP is enabled rather than the presence of the key. This issue leaded to inconsistant sysconfig/network-scripts on fedora. 'BOOTPROTO' was always 'dhcp', even if the address config was static. After this change a dhcp subnet is added only if the 'dhcp' setting in source cfg dict is True. LP: #1818032
2019-02-27cc_apt_pipelining: stop disabling pipelining by defaultDaniel Watkins
This was introduced due to Ubuntu using S3 mirrors, and S3 having a buggy pipelining implementation. Those Ubuntu mirrors are no longer in production and, furthremore, apt has also grown the ability to handle servers with broken pipelining. As such, we can stop disabling pipelining, which should result in improved apt download speeds. LP: #1794982
2019-02-26tests: fix some slow tests and some leaking stateDaniel Watkins
In test_ds_identify, don't mutate otherwise-static test data. When running tests in a random order, this was causing failures due to breaking preconditions for other tests. In tests/helpers, reset logging level in tearDown. Some of the CLI tests set the level of the root logger in a way that isn't correctly reset. For test_poll_imds_re_dhcp_on_timeout and test_dhcp_discovery_run_in_sandbox_warns_invalid_pid, mock out time.sleep; this saves ~11 seconds (or ~40% of previous test time!).
2019-02-26util: don't determine string_types ourselvesDaniel Watkins
six already provides this for us, and we're already paying the cost to determine it there; no need to do it twice.
2019-02-26cc_rsyslog: Escape possible nested setDaniel Watkins
Under Python 3.7, we are seeing `FutureWarning: Possible nested set at position 23`; escaping this bracket causes that warning to disappear. LP: #1816967
2019-02-25Enable encrypted_data_bag_secret support for ChefEric Williams
Encrypted data bags require a secrets file to be present to decrypt, and the location of the file must be configured the Chef client configuration file, client.rb. This update enables cloud-init's chef module to update that setting in client.rb. LP: #1817082
2019-02-22azure: Filter list of ssh keys pulled from fabricJason Zions (MSFT)
The Azure data source is expected to expose a list of ssh keys for the user-to-be-provisioned in the crawled metadata. When configured to use the __builtin__ agent this list is built by the WALinuxAgentShim. The shim retrieves the full set of certificates and public keys exposed to the VM from the wireserver, extracts any ssh keys it can, and returns that list. This fix reduces that list of ssh keys to just the ones whose fingerprints appear in the "administrative user" section of the ovf-env.xml file. The Azure control plane exposes other ssh keys to the VM for other reasons, but those should not be added to the authorized_keys file for the provisioned user.
2019-02-14EC2: Rewrite network config on AWS Classic instances every bootGuilherme G. Piccoli
AWS EC2 instances' network come in 2 basic flavors: Classic and VPC (Virtual Private Cloud). The former has an interesting behavior of having its MAC address changed whenever the instance is stopped/restarted. This behavior is not observed in VPC instances. In Ubuntu 18.04 (Bionic) the network "management" changed from ENI-style (etc/network/interfaces) to netplan, and when using netplan we observe the following block present in /etc/netplan/50-cloud-init.yaml: match: macaddress: aa:bb:cc:dd:ee:ff Jani Ollikainen noticed in Launchpad bug #1802073 that the EC2 Classic instances were booting without network access in Bionic after stop/restart procedure, due to their MAC address change behavior. It was narrowed down to the netplan MAC match block, that kept the old MAC address after stopping and restarting an instance, since the network configuration writing happens by default only once in EC2 instances, in the first boot. This patch changes the network configuration write to every boot in EC2 Classic instances, by checking against the "vpc-id" metadata information provided only in the VPC instances - if we don't have this metadata value, cloud-init will rewrite the network configuration file in every boot. This was tested in an EC2 Classic instance and proved to fix the issue; unit tests were also added for the new method is_classic_instance().

2019-02-08netinfo: Adjust ifconfig output parsing for FreeBSD ipv6 entriesRyan Harper
FreeBSD ifconfig output for ipv6 addrs doesn't find scopeid values when present in the output and the pformat rendering assumes that an ipv6 address will have a 'scope6' entry in the netdev info dictionary. This patch finds the scopeid value, which is not always inside <>, and in some cases v6 addrs don't have a scopeid value in the output, so when rendering the table, allow scope6 value to be replaced with the empty value. LP: #1779672
2019-02-07netplan: Don't render yaml aliases when dumping netplanRyan Harper
Cloud-init rendered netplan with duplicate aliases if a network config included "global" nameserver/search values. Netplan uses can read yaml files which do use aliaes but cloud-init did not render a single yaml dictionary, instead it combined yaml sections into a single document which sometimes resulted in duplicate aliases being present. This branch introduces a yaml SafeDumper class which can set the 'ignore_aliases' attribute. This is not enabled by default but callers to util.yaml_dumps can pass a boolean to toggle this. The netplan render uses noalias=True and the resulting yaml output does not contain any aliases. LP: #1815051
2019-01-31clean: cloud-init clean should not trace when run from within cloud_dirChad Smith
Avoid traceback when cloud-init clean is run from within /var/lib/cloud/ deleted dirs. LP: #1795508

Fixes: - flake8: use ==/!= to compare str, bytes, and int literals - pycodestyle: E117 over-indented
2019-01-28opennebula: also exclude epochseconds from changed environment varsChad Smith
In addition to EPOCHREALTIME there is also an EPOCHSECONDS environment variable that OpenNebula needs to exclude as it is expected to change. This commit supplements the other exclusion in commit d1a2fe7307e9cf2251d1f9a666c12d71d3f522d6. Without this fix, unittests will intermittently fail if parse_shell_config is run across a timing boundary where the EPOCHSECONDS changes mid-test. LP: #1813641

2019-01-26opennebula: exclude EPOCHREALTIME as known bash env variable with a deltaChad Smith
This branch is needed to allow cloud-init to sbuild on Ubuntu Disco. OpenNebula:parse_shell_config tries to do a comparison of bash environment values, excluding expected environment variables which are known to change. Bash on Ubuntu Disco surfaces a new EPOCHREALTIME environment variable which wasn't in previous bash environments, this var needs to be ignored by parse_shell_config too. LP: #1813383
2019-01-25lxd: install zfs-linux instead of zfs meta packageJohnson Shi
When using the LXD module cloud-init will attempt to install ZFS if it does not exist on the target system. However instead of installing the `zfsutils-linux` package it attempts to install `zfs` resulting in an error. Ubuntu Xenial (16.04) has zfs meta package, but Bionic (18.04) does not. Use the specific base package instead of zfs meta. Co-authored-by: Michael Skalka <michael.skalka@canonical.com> LP: #1799779
2019-01-23net/sysconfig: do not write a resolv.conf file with only the header.Robert Schweikert
Writing the file with no dns information may prevent distro tools from writing a resolv.conf file with dns information obtained from a dhcp server.
2019-01-18net: Make sysconfig renderer compatible with Network Manager.Eduardo Otubo
The 'sysconfig' renderer is activated if, and only if, there's ifup and ifdown commands present in its search dictonary or the network-scripts configuration files are found. This patch adds a check for Network- Manager configuration file as well. This solution is based on the use of the plugin 'ifcfg-rh' present in Network-Manager and is designed to support Fedora 29 or other distributions that also replaced network-scripts by Network-Manager.
2019-01-15cc_set_passwords: Fix regex when parsing hashed passwordsMarlin Cremers
Correct invalid regex to match hashes starting with the following: - $1, $2a, $2y, $5 or $6 LP: #1811446
2019-01-15net: Wait for dhclient to daemonize before reading lease fileJason Zions
cloud-init uses dhclient to fetch the DHCP lease so it can extract DHCP options. dhclient creates the leasefile, then writes to it; simply waiting for the leasefile to appear creates a race between dhclient and cloud-init. Instead, wait for dhclient to be parented by init. At that point, we know it has written to the leasefile, so it's safe to copy the file and kill the process. cloud-init creates a temporary directory in which to execute dhclient, and deletes that directory after it has killed the process. If cloud-init abandons waiting for dhclient to daemonize, it will still attempt to delete the temporary directory, but will not report an exception should that attempt fail. LP: #1794399
2019-01-15[Azure] Increase retries when talking to Wireserver during metadata walkJason Zions
Testing startup of large numbers of VMs (of varying distros) in Azure shows that 3 retries results in a small percentage of failed VMs. Increasing that by a few dramatically decreases the occurrence of provisioning timeout errors. The initial choice of "3 retries" was uninformed by heavy testing. Also, the alternate provisioning mechanism for Azure (waagent) retries the Wireserver crawl without limit. 10 retries seems a more reasonable choice.
