Add a parameter to station_set_scan_results to allow skipping the
removal of old BSSes. In the DBus-triggered scan only expire BSSes
after having gone through the full supported frequency set.
It should be safe to pass partial scan results to
station_set_scan_results() when not expiring BSSes so using this new
parameter I guess we could also call it for roam scan results.
A scan normally takes about 2 seconds on my dual-band wifi adapter when
connected. The drivers will normally probe on each supported channel in
some unspecified order and will have new partial results after each step
but the kernel sends NL80211_CMD_NEW_SCAN_RESULTS only when the full
scan request finishes, and for segmented scans we will wait for all
segments to finish before calling back from scan_active() or
scan_passive().
To improve user experience define our own channel order favouring the
2.4 channels 1, 6 and 11 and probe those as an individual scan request
so we can update most our DBus org.connman.iwd.Network objects more
quickly, before continuing with 5GHz band channels, updating DBus
objects again and finally the other 2.4GHz band channels.
The overall DBus-triggered scan on my wifi adapter takes about the same
time but my measurements were not very strict, and were not very
consistent with and without this change. With the change most Network
objects are updated after about 200ms though, meaning that I get most
of the network updates in the nm-applet UI 200ms from opening the
network list. The 5GHz band channels take another 1 to 1.5s to scan and
remaining 2.4GHz band channels another ~300ms.
Hopefully this is similar when using other drivers although I can easily
imagine a driver that parallelizes 2.4GHz and 5GHz channel probing using
two radios, or uses 2, 4 or another number of dual-band radios to probe
2, 4, ... channels simultanously. We'd then lose some of the
performance benefit. The faster scan results may be worth the longer
overall scan time anyway.
I'm also assuming that the wiphy's supported frequency list is exactly
what was scanned when we passed no frequency list to
NL80211_CMD_TRIGGER_SCAN and we won't get errors for passing some
frequency that shouldn't have been scanned.
Use the hwsim DBus API rather than command line. This both is
faster and more dynamic than doing so with the command line.
This also avoids tracking the radio ID since we can just hang
on to the radio Dbus object directly.
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.
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.
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.
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.
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.
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.
For better reliability the processor count is now set to qemu.
In cases of low CPU count (< 2) hosts the processor count is
limited to 1. Otherwise half of the host cores will be used for
the VM.
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.
Allow the storage directory (default /tmp/iwd) to be configured
just like the state directory. This is in order to support multiple
IWD instances which require separate storage directories for network
provisioning files.
The docs just specified what a IP prefix looks like, not an
actual example. Though its not recommended to just copy paste
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.
In the strange case that the dns list or the domain list are empty and
openresolv is being used, delete the openresolv entry instance instead
of trying to set it to an empty value
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.
Due to timing this test sometimes does not pass because it was
just asserting on the device state rather than waiting for a
change. This generally worked but not always.

Fix the AlwaysRandomizeAddress setting name.
Add the stricter specification of the extension syntax.
Clarify that GTC and MD5 can't be used as outer EAP methods with wifi.
Tracking of addresses that weren't set by us seemed a bit questionable.
Take this out for now. If this is ever needed, then a queue with
l_rtnl_address objects should be used.
Introduce a new v4_address member which will hold the currently
configured IPV4 address (static or obtained via DHCP). Use the new
l_rtnl_address class for this.
As a side-effect, lease expiration will now properly remove the
configured address.
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.
This patch converts the code to use the new l_rtnl_route class instead
of using l_rtnl_route6* utilities. The settings parsing code will now
return an l_rtnl_route object which can be installed directly.
Also, the route removal path has been removed since netconfig_reset()
sets disable_ipv6 setting to '1' which will remove all IPV6 routes and
addresses for the interface.
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.
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.
Both these tests create many radios which sometimes causes timing
problems when hwsim is running. Since hwsim is not required for
these tests we can disable it and increase test reliability.
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.
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.
This can result in strange test results since there was no less
than zero checks before subtracting the total tests from failed
tests. In case of an internal exception we can just set all values
to zero. This will be handled specially as we do for timeout
errors.
