When obtaining information from "ip addr", default to using
"ip --json addr" rather than using regex to parse "ip addr show"
as json is machine readable as less prone to error.
Deprecate but leave fallback to use "ip addr" for older iproute2
tooling which does not support --json param.
Fix regex parsing of "ip addr" to support peer addresses and
metrics.

Applied Black and isort, fixed any linting issues, updated tox.ini
and CI.

This was painful, but it finishes a TODO from cloudinit/subp.py.
It moves the following from util to subp:
ProcessExecutionError
subp
which
target_path
I moved subp_blob_in_tempfile into cc_chef, which is its only caller.
That saved us from having to deal with it using write_file
and temp_utils from subp (which does not import any cloudinit things now).
It is arguable that 'target_path' could be moved to a 'path_utils' or
something, but in order to use it from subp and also from utils,
we had to get it out of utils.

Add support for the NetBSD Operating System.
Features in this branch:
* Add BSD distro parent class from which NetBSD and FreeBSD can
specialize
* Add *bsd util functions to cloudinit.net and cloudinit.net.bsd_utils
* subclass cloudinit.distro.freebsd.Distro from bsd.Distro
* Add new cloudinit.distro.netbsd and cloudinit.net.renderer for
netbsd
* Add lru_cached util.is_NetBSD functions
* Add NetBSD detection for ConfigDrive and NoCloud datasources
This branch has been tested with:
- NoCloud and OpenStack (with and without config-drive)
- NetBSD 8.1. and 9.0
- FreeBSD 11.2 and 12.1
- Python 3.7 only, because of the dependency oncrypt.METHOD_BLOWFISH.
This version is available in NetBSD 7, 8 and 9 anyway

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.

Fix remaining pycodesytle warnings related to invalid string literals
introduced in more recent pycodeflakes versions
https://bugs.python.org/issue27364 .
Also stop using flake8 in tox as it is incompatible with newer versions of
pyflakes. Instead we now add tox environments for pycodestyle and pyflakes
individually.
Set the versions in both pycodestyle and pyflakes to the currently
available versions.

The last set of changes to netdev_pformat ended up dropping the output
of devices that were not up. This adds back the 'down' interfaces to the
rendered output.
LP: #1766302
|

The net-tools package is deprecated and will eventually be dropped. Use
"ip route", "link" or "address" instead of "ifconfig" or "route" calls.
Cloud-init can now run in an environment that no longer has net-tools.
This affects the network and route printing emitted to
cloud-config-output.log as well as the cc_disable_ec2_metadata module.
Additional changes:
- separate readResource and resourceLocation into standalone test
functions
- Fix ipv4 address rows to report scopes represented by ip addr show
- Formatted route/address ouput now handles multiple ipv4 and ipv6
addresses on a single interface

Output in cloud-init-output.log contained only the string representation
of a SimpleTable object instead of the table formatted content. This bug
also affected ssh_authkey_fingerprints.
LP: #1722566
|
|
The first revision of this rendered tables with less decoration but there
was a desire upstream to avoid possibly breaking some parsing someone
might be doing, so it has been revised to render the same as prettytable
for the cases cloud-init actually uses.
|
|
On systems with selinux enabled, some of the networking commands executed
successfully do not return 0. Allow these commands to return 1 since the
output is valid.
Ultimately we need to get this information in some way so that we can
display it correctly. For now, work around the stack trace when selinux
does not allow us to collect it.

This has been a recurring ask and we had initially just made the change to
the cloud-init 2.0 codebase. As the current thinking is we'll just
continue to enhance the current codebase, its desirable to relicense to
match what we'd intended as part of the 2.0 plan here.
- put a brief description of license in LICENSE file
- put full license versions in LICENSE-GPLv3 and LICENSE-Apache2.0
- simplify the per-file header to reference LICENSE
- tox: ignore H102 (Apache License Header check)
Add license header to files that ship.
Reformat headers, make sure everything has vi: at end of file.
Non-shipping files do not need the copyright header,
but at the moment tests/ have it.

`tox -e py27` passes full test suite. Now to work on replacing mocker.

After the routeinfo function started to return
a dictionary containing ipv4 and ipv6 information
we now need to make sure we search the appropriate
key.
|
|
Instead of failing when IPv6 information is not found we
should be more tolerant of said information not existing
so that we behave like the pre IPv6 addition.
|
|
This patch does the following:
1. Adds support to process network config with IPv6
2. Adds support to display 'ifconfig -a' information for IPv6
3. Adds support to display routing information for IPv6

after freebsd merge, ubuntu shows addr:v.x.y.z instead of v.x.y.z for the
ipv4 address. This should fix that by just skipping the 'inet' (or inet6)
token if the next token starts with 'addr:'.

This fixes up many long lines to be < 80 chars and some other
pylint issues. pylint 1.1 (in trusty) is now complaining about
the lazy logging, so I'll clean that up when I touch things.

in order to work on python 2.6, replace usage of check_output with util.subp.

If you were trying to parse this output with something, an empty field would be
difficult to handle, as you'd have to know the expected lengths of each field.
The '.' means empty, but then all fields are non-whitespace delimited by one or
more whitespace.

This copyright change reflects previous changes that Juerg made for pylint and
pep8 cleanups.

When 'cloud-init start' (network) runs, it will print information
about the systems network info to the console. This will help in debugging
instances.
