Add support for Infiniband network interfaces (IPoIB).
OpenStack ironic references Infiniband interfaces via a 6 byte 'MAC
address' formed from bytes 13-15 and 18-20 of interface's hardware
address. This address is used as the ethernet_mac_address of Infiniband
links in network_data.json in configdrives generated by OpenStack nova.
We can use this address to map links in network_data.json to their
corresponding interface names.
When generating interface configuration files, we need to use the
interface's full hardware address as the HWADDR, rather than the 6 byte
MAC address provided by network_data.json.
This change allows IB interfaces to be referenced in this dual mode - by
MAC address and hardware address, depending on the context.
Support TYPE=InfiniBand for sysconfig configuration of IB interfaces.
cli: add cloud-init query subcommand to query instance metadata
Cloud-init caches any cloud metadata crawled during boot in the file
/run/cloud-init/instance-data.json. Cloud-init also standardizes some of
that metadata across all clouds. The command 'cloud-init query' surfaces a
simple CLI to query or format any cached instance metadata so that scripts
or end-users do not have to write tools to crawl metadata themselves.
Since 'cloud-init query' is runnable by non-root users, redact any
sensitive data from instance-data.json and provide a root-readable
unredacted instance-data-sensitive.json. Datasources can now define a
sensitive_metadata_keys tuple which will redact any matching keys
which could contain passwords or credentials from instance-data.json.
Also add the following standardized 'v1' instance-data.json keys:
- user_data: The base64encoded user-data provided at instance launch
- vendor_data: Any vendor_data provided to the instance at launch
- underscore_delimited versions of existing hyphenated keys:
instance_id, local_hostname, availability_zone, cloud_name
pylint: ignore warning assignment-from-no-return for _write_network
Distro subclasses arch, freebsd and debian still have a path with an
implemented _write_network method which has a return value. Can drop
this pylint ignore when _write_network is dropped from arch, freebsd
and debian.
stages: Fix bug causing datasource to have incorrect sys_cfg.
The Init object had a bug/odd side effect where when retrieving a distro
object it would update the datasources's sys_cfg. That was probably
intended to refresh the possibly stale config stored there. Unfortunately
what it actually did limit the config there to the 'system_info' top level
key where initially it had the whole config.
Any distro that has a '_write_nework_config' method should no
longer get their _write_network called at all. So lets drop
that code and raise a RuntimeError any time we got there.
Replace the one caller of 'apply_network' (legacy openstack path)
with a call to apply_network_config after converting the ENI to
network config.
