2020-09-08cc_vyos: T2726: User creating optimizations and small fixeszsdc
This commit is addressed to solve some old issues with creating users in the system and simplify the parts of the module related to this. Also, some small fixes. - removed Python modules os, cloudinit.stages, cloudinit.util dependencies. Related functionality replaced by other modules (see below) - detection of hashed passwords was simplified, made 100% compatible with the rest Cloud-init documentation and recommendations. Also, it was moved from the `handle` function to the `set_pass_login` to reduce the code size and make it more clear - replaced sequenced SSH public keys enumeration for keys without comments to UUID-based to simplify the code and make the logic easier - replaced home-growed SSH key parser/checker to the native cloudinit.ssh_util.AuthKeyLineParser() - added support for SSH key options configuration - added possibility to use all key types supported by VyOS: 'ssh-dss', 'ssh-rsa', 'ecdsa-sha2-nistp256', 'ecdsa-sha2-nistp384', 'ssh-ed25519', 'ecdsa-sha2-nistp521' - fixed typo in configuration for `distance`/`metric` option in set_config_interfaces_v1() - added the stable format of the Meta-Data: `v1`. It must be absolutely equal for any datasource, therefore it is always better to use data from it than from any other sources if this is possible - added User-Data and Vendor-Data logging. Currently not used for anything, but required for a proper debugging - replaced datasource source from the unstable metadata field to the stable `cloud.datasource.dsname` - replaced Network-Config source from `init._find_networking_config()` to the more correct `cloud.datasource.network_config` - replaced hostname source from the `util.get_hostname_fqdn()` to `cloud.get_hostname()`, what is actually the same, to drop `util` dependency - the part specific for Azure cloud united with the main part of users creating code, since there is actually no platform-specific functions and everything was moved to the common places, what improved compatibility with the similar environments - rewritten users creating logic **Important information about users and credentials** In the Cloud-init exists multiple ways of how to configure authentication: public keys in Meta-Data, default user name and options in the main config file, several config modules (`cc_set_passwords`, `cc_ssh`, `cc_users_groups`) configurable via `#cloud-config`, maybe something more. Cloud-Init solves this by merging information from most of these sources to a single users' database, but information can overwrite each other. Very simplified logic description: if something is configured in a User-Data (`#cloud-config`), then most likely default values like username `vyos`, or SSH public keys from Meta-Data will be dropped by Cloud-Init. This implementation should apply public SSH keys and passwords without associated username to the default user (usually `vyos`, but some platforms may allow using your own). If you are creating any additional user, a default one will not be created and common authentication methods will not be applied, so you need to provide the complete authentication details for it.
2020-07-30cc_vyos: T2403: Resolved IP addresses configuration conflictszsdc
This commit fixes a situation when it is necessary to configure more than one IP address on an interface. Previously only the latest one address survived. With this fix, it is possible to add all compatible addresses.
2020-07-23cc_vyos: T2403: Network configuration and module optimizationzsdc
Changes: - added logging messages - optimized structure - added back network configuration version 1 support (new implementation) - fixed static gateway settings in network configuration version 2
2020-04-17Cloud-init: T2309: Added filter to host-name and code cleanupzsdc
Since not all data-sources filter hostname in Meta-Data, we need to be sure that the value received from Meta-Data can be applied to the system. The new filter cut all prohibited symbols and takes only that part of the filtered result, which can be used as a hostname. Additionally, the source was cleaned where it is possible, according to linter recommendations.
2020-03-11Cloud-init: T2117: Updated to 20.1zsdc
- Merge 20.1 version from the Canonical repository - Removed unneeded changes in datasources (now only OVF datasource is not equal to upstream's version) - Adapted cc_vyos module to new Cloud-init version - Changed Jenkinsfile to use build scripts, provided by upstream

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

2020-01-23Do not use fallocate in swap file creation on xfs. (#70)Eduardo Otubo
When creating a swap file on an xfs filesystem, fallocate cannot be used. Doing so results in failure of swapon and a message like: swapon: swapfile has holes The solution here is to maintain a list (currently containing only XFS) of filesystems where fallocate cannot be used. The, on those fileystems use the slower but functional 'dd' method.

2020-01-23Update debian eni network configuration location, retain Ubuntu settingJanos Lenart
On Debian, ifupdown uses `source-directory /etc/network/interfaces.d` (for new installs) to include files. https://salsa.debian.org/debian/ifupdown/blob/master/debian/postinst#L23 The current filename, 50-cloud-init.cfg, does not match against the RE that is used to scan the directory for configurations (ASCII upper- and lower-case letters, ASCII digits, ASCII underscores, and ASCII minus-hyphens): https://salsa.debian.org/debian/ifupdown/blob/master/interfaces.5.pre#L122 Of course many installations use `source /etc/network/interfaces.d/*`, but not all.

2020-01-16util: rename get_architecture to get_dpkg_architecture (#173)Daniel Watkins
This makes it clearer that we should only use this in code paths that will definitely have dpkg available to them. - Rename get_architecture -> get_dpkg_architecture - Add docstring to get_dpkg_architecture
2020-01-16Ensure util.get_architecture() runs only once (#172)Ryan Harper
* Ensure util.get_architecture() runs only once util.get_architecture() recently was wrapped using python3's lru_cache() which will cache the result so we only invoke 'dpkg --print-architecture' once. In practice, cloud-init.log will show multiple invocations of the command. The source of this was that the debian Distro object implements the get_primary_arch() with this command, but it was not calling it from util, but issuing a util.subp() directly. This branch also updates cc_apt_configure methods to fetch the arch value from the distro class, and then ensure that the methods apt_configure calls pass the arch value around. * utils: remove lsb_release and get_architecture wrappers The original lsb_release wrapper was used to prevent polluting the single value we cached, however lru_cache() already handles this case by using args, kwargs values to cache different calls to the method. * rename_apt_list: use all positional parameters
2020-01-14Only use gpart if it is the BSD gpart (#131)Conrad Hoffmann
Currently, cloud-init will happily try to run `gpart` on Linux even though on most distributions this a different tool [1]. Extend the availability check to make sure the `gpart` present is really the BSD variant, to avoid accidental execution. Also add a pointer to the docs, so that people do not try to install gpart on Linux in the expectation it will work with this module. [1] https://github.com/baruch/gpart

2020-01-08Make tests work with Python 3.8 (#139)Conrad Hoffmann
* Make DistroChecker test work with Python 3.8 In Python 3.8, `platform.linux_distribution` has been removed. This was anticipated, and the cloud-init code uses its own `util.get_linux_distro` instead, which works fine w/o `platform.linux_distribution`. However, these tests still try to mock the platform function, which fails if it doesn't exist (Python 3.8). Instead, mock the new function here, as this is a test for code that depends on it rather than the function itself. * Make GetLinuxDistro tests work with Python 3.8 In Python 3.8, `platform.dist` was removed, so allow mock to create the function by setting `create=True`. * Make linter happy in Python 3.8 Suppress E1101(no-member) as this function was removed.

2019-12-20freebsd: introduce the freebsd renderer (#61)Gonéri Le Bouder
* freebsd: introduce the freebsd renderer Refactoring of the FreeBSD code base to provide a real network renderer for FreeBSD. Use the generic update_sysconfig_file() from rhel_util to handle the access to /etc/rc.conf. Interfaces are not automatically renamed by FreeBSD using the following configuration in /etc/rc.conf: ``` ifconfig_fxp0_name="eth0" ``` * freesd: use regex named groups Reduce the complexity of `get_interfaces_by_mac_on_freebsd()` with named groups. * freebsd: breaks up _write_network() in tree small functions - `_write_ifconfig_entries()` - `_write_route_entries()` - `_write_resolve_conf()` * extend find_fallback_nic() to support FreeBSD this uses `route -n show default` to find the default interface * freebsd: use dns keys from NetworkState class The NetworkState class (settings instance) exposes the DNS configuration in two keys: - `dns_nameservers` - `dns_searchdomains` On OpenStack, these keys are set when a global DNS server is set. The alternative is the `dns_nameservers` and `dns_search` keys from each subdomain. We continue to read those. * freebsd: properly target the /etc/resolv.conf file * freebsd: ignore 'service routing restart' ret code On FreeBSD 10, the restart of routing and dhclient is likely to fail because - routing: it cannot remove the loopback route, but it will still set up the default route as expected. - dhclient: it cannot stop the dhclient started by the netif service. In both case, the situation is ok, and we can proceed. * freebsd: handle case when metadata MAC local locally Handle the case where the metadata configuration comes with a MAC that does not exist locally. See: - https://github.com/canonical/cloud-init/pull/61/files/635ce14b3153934ba1041be48b7245062f21e960#r359600604 - https://github.com/canonical/cloud-init/pull/61/files/635ce14b3153934ba1041be48b7245062f21e960#r359600966 * freebsd: show up a warning if several subnet found The FreeBSD provider currently only allow one subnet per interface. * freebsd: honor the target parameter in _write_network * freebsd: log when a bad route is found * freebsd: pass _postcmds to start_services() * freebsd: updatercconf() is depercated Replace `updatercconf()` by `rhel_util.update_sysconfig_file()`. * freebsd: ensure gateway is ipv4 before using it With the legacy ENI format, an IPv6 gateway may be pushed. This instead of the expected IPv4. * freebsd: find_fallback_nic, support FB10 On FreeBSD <= 10, `ifconfig -l` ignores the down interfaces. * freebsd: use util.target_path() to load resolv.conf Ensure we access `/etc/resolv.conf`, not `etc/resolv.conf`. * freebsd: skip subnet without netmask Those are likely to be either invalid of in IPv6 format. IPv6 support will be addressed later in a new patchset. * freebsd: get_devicelist returns netif list Ensure `get_devicelist()` returns the list of known netif on FreeBSD. * replace rhel_util.update_sysconfig_file wrapper call, with a wrapper function * reverse if condition to remove an indent Co-authored-by: Igor Galić <me+github@igalic.co>

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.
