Can now pass -V, --valgrind to test-runner to run valgrind on
iwd during autotests. Note: the verbose option for iwd must
also be passed in order to see output (-v iwd).
SA Query procedure is used when an unprotected disassociate frame
is received (with frame protection enabled). There are two code
paths that can occur when this disassociate frame is received:
1. Send out SA Query and receive a response from the AP within a
timeout. This means that the disassociate frame was not sent
from the AP and can be ignored.
2. Send out SA Query and receive no response. In this case it is
assumed that the AP went down ungracefully and is now back up.
Since frame protection is enabled, you must re-associate with
the AP.
Two autotests:
1. Tests SA Query procedure when the AP goes down. In this case the AP
goes down ungracefully, now allowing it to send out any deauth
frames. When the AP comes back up, IWD still thinks its connected.
The AP will then send unprotected disassociate frames so the client
can re-connect. This kicks off the SA Query procedure, which the AP
will not respond to. At this point we can deauth and reconnect to
the AP.
2. Test SA Query procedure when a disassociate frame has been spoofed.
In this case we receive an unprotected disassociate frame and start
SA Query. The AP should then respond to the SA query within the
timeout. We then know the frame was spoofed and can remain
connected.
Changed disassociate reason to 0x07 when spoofing a disassociate
frame. This along with 0x06 are the only two reason codes that
should be accepted in an unprotected disassociate frame.
Using the hwsim dbus interface ".Interface" under the radios
object you can now send an arbitrary frame out from that radio.
Two methods have been added, spoof_frame and spoof_disassociate.
The hwsim SendFrame method requires the radio frequency which
is obtained from the hostapd config file. This adds a generic
API to get any config value from the hostapd config, as well
as a get_freq API that converts the channel number to a
frequency.
Added a new method SendFrame() under the radios .Interface
interface. This method takes two byte arrays as parameters,
first is the station address to send the frame to, and the
second is the raw frame data.
For testing SA Query, the autotest needs the ablility to force
kill (and restart) hostapd without giving it time to deauth its
stations gracefully. A method was added to the HostapdCLI class
which does a killall -9 hostapd, resets the wlnX interface,
and restarts hostapd with the same arguments as it had before.
The following verbose options can be used:
"unit" - see output from unit tests
"kernel" - see hwsim kernel prints
"pytests" - see prints from python autotests
The existing verbose option would turn on debug logging for most
processes in the test-runner framework. This change makes the verbose
option more granular. The --verbose or -v option should now be
followed by a comma separated list of the test-runner processes you
want to see debug logging from. Currently iwd, hwsim, ofonod, and
hostapd are valid options to pass to the verbose flag e.g.
-v iwd,hwsim,ofonod,hostapd
Or any single/combination of the above applications.
1. Enforce implementation of handle_request function
2. In case of unimplemented handle_retransmit try to use
handle_request instead and rely on method specific
mechanism to restart the conversation if necessary
3. Make method->free implementation unrequired
When we call scan_periodic_stop and a periodic scan is in progress (i.e.
the trigger callback has been called already) we get no new callback
from scan.c and the device Scanning property remains True forever so set
it to False.
The change from scan_periodic_stop to periodic_scan_stop looks silly but
it's consistent with our naming :)
This patch adds a watcher/parser for the frame event associated with
an AP directed BSS transition (AP roaming). When the AP sends a BSS
transition request, this will parse out the BSS candidate list
(neighbor report) and initiate a roam scan. After this point the
existing roaming code path is reused.
The AuthCenter will now wait for the RX thread to start before
continuing with the test.
Also removed the non blocking option and fixed the loop to
handle a blocking recvfrom call.
