5567caf64a hwsim: add iftype/cipher disabling through DBus
Update the Dbus API to allow disabling iftypes and ciphers
just as you can with the command line.

6a1853b01a hwsim: change radio Create() to take a dictionary
The Create() API was limited to only taking a Name and boolean
(for p2p enabling). The actual hwsim nl80211 API can take more
attributes than this (which are actually utilized when creating
from the command line). To get the DBus API up to the same
functionality the two arguments in Create were replaced with
a single dictionary. This allows for extending later if more
arguments are needed.

eaf176220c auto-t: fix hwsim.py to use Destroy rather than Remove

799ab03f59 hwsim: check pending_create_msg before replying
In the NEW_RADIO callback hwsim was assuming that DBus had no
yet replied to the Create() method. In some cases the NEW_RADIO
event fires before the actual callback which will respond to
DBus. This causes a crash in the create callback.

554a78fbf0 hwsim: add --no-register option
Starts hwsim but does not register to mac80211_hwsim. This is to
allow autotests to disable hwsim, while still having the ability
to create/destroy radios over DBus.

0193940e50 client: ignore control sequence length in prompt
Readline uses the characters \001 and \002 to mark the start and end
of zero-length character sequnces in the prompt before prompt
expansion. Without these characters the input point can become offset
from the visual end of the prompt when performing some actions.

fde1012f5d auto-t: add static netconfig test
Tests netconfig with a static configuration, as well as tests ACD
functionality.

The test has two IWD radios which will eventually use the same IP.
One is configured statically, one will receive the IP via DHCP.
The static client sets its IP first and begins using it. Then the
DHCP client is started. Since ACD in a DHCP client is configured
to use its address indefinitely, the static client *should* give
up its address.

f39d1b4ac2 netconfig: add ACD client for static configuration
When the IP is configured to be static we can now use ACD in
order to check that the IP is available and not already in
use. If a conflict is found netconfig will be reset and no IP
will be set on the interface. The ACD client is left with
the default 'defend once' policy, and probes are not turned
off. This will increase connection time, but for static IP's
it is the best approach.

d2cc033d09 auto-t: pass namespace on to other IWD classes
Certain classes were still using the default namespace. This
didn't matter yet since testAP was the only test using namespaces,
and the AP interface was the only one being used.

For an IWD station on a separate namespace all objects need to
be accessable, so the namespace is passed along to those as needed.

4353110684 doc: use real example for APRanges
The docs just specified what a IP prefix looks like, not an

blindly, its still useful to have some value in the man pages
that actually works if someone just wants to get a DHCP server
working.

b647f8e1f0 network: clear info of removed known network before disconnect
Make sure to erase the network_info of a known network that has been
removed before disconnecting any stations connected to it. This fixes
the following warning observed when forgetting a connected network:

  WARNING: ../git/src/network.c:network_rank_update() condition n < 0 failed

This also fixes a bug where such a forgotten network would incorrectly
appear as the first element in the response to GetOrderedNetworks().  By
clearing the network_info, network_rank_update() properly negates the
rank of the now-unknown network.

eb151efc81 netconfig: Rework static IPv6 address handling
This patch converts the code to use the new l_rtnl_address class.  The
settings parsing code will now return an l_rtnl_address object which
can be installed directly.

Also, address removal path for static addresses has been removed, since
netconfig_reset() sets disable_ipv6 setting to '1', which will remove
all IPV6 addresses for the interface.

Also, the route removal path has been removed since netconfig_reset()

e1e1c4edd1 test-runner: introduce network namespaces
Our simulated environment was really only meant to test air-to-air
communication by using mac80211_hwsim. Protocols like DHCP use IP
communication which starts to fall apart when using hwsim radios.
Mainly unicast sockets do not work since there is no underlying
network infrastructure.

In order to simulate a more realistic environment network namespaces
are introduced in this patch. This allows wireless phy's to be added
to a network namespace and unique IWD instances manage those phys.
This is done automatically when 'NameSpaces' entries are configured
in hw.conf:

[SETUP]
num_radios=2

[NameSpaces]
ns0=rad1,...

This will create a namespace named ns0, and add rad1 to that
namespace. rad1 will not appear as a phy in what's being called the
'root' namespace (the default namespace).

As far as a test is concerned you can create a new IWD() class and
pass the namespace in. This will start a new IWD instance in that
namespace:

ns0 = ctx.get_namespace('ns0')
wd_ns0 = IWD(start_iwd=True, namespace=ns0)

'wd_ns0' can now be used to interact with IWD in that namespace, just
like any other IWD class object.

c46a5d7c84 netconfig: Install DNS addresses obtained from DHCPv6
This also changes the resolve API a little bit to act as a 'set' API
instead of an incremental 'add' API.  This is actually easier to manage
in the resolve module since both systemd and resolvconf want changes
wholesale and not incrementally.

845658bd32 station: get neighbor reports early
Waiting to request neighbor reports until we are in need of a roam
delays the roam time, and probably isn't as reliable since we are
most likely in a low RSSI state. Instead the neighbor report can
be requested immediately after connecting, saved, and used if/when
a roam is needed. The existing behavior is maintained if the early
neighbor report fails where a neighbor report is requested at the
time of the roam.

The code which parses the reports was factored out and shared
between the existing (late) neighbor report callback and the early
neighbor report callback.

a6808aa55a auto-t: introduce new autotest syntax
Sometimes improperly written tests can end up causing future tests
to fail. For faster debugging you can now add a '+' after a given
autotest which will start that test and run all tests which come
alphabetically after it (as if you are running a full autotest suite).

Example:

./test-runner -A testWPA+

This will run testWPA, testWPA2, testWPA2-no-CCMP, testWPA2-SHA256,
and testWPA2withMFP.

eb92c0a6e5 auto-t: refactor get_instance from iwd.py
When network namespaces are introduced there may be multiple
IWD class instances. This makes IWD.get_instance ambiguous
when namespaces are involved. iwd.py has been refactored to
not use IWD.get_instance, but testutil still needs it since
its purely based off interface names. Rather than remove it
and modify every test to pass the IWD object we can just
maintain the existing behavior for only the root namespace.

4bf8bf2396 test-runner: add option to specify subtests to run
You can now specify a limited list of subtests to run out of a
full auto-test using --sub-tests,-S. This option is limited in
that it is only meant to be used with a single autotest (since
it doesn't make much sense otherwise).

The subtest can be specified both with or without the file
extension.

Example usage:

./test-runner -A testAP -S failure_test,dhcp_test.py

This will only run the two subtests and exclude any other *.py
tests present in the test directory.
