Register P2P group's vendor IE writers using the new API to build and
attach the necessary P2P IE and WFD IEs to the (Re)Association Response,
Probe Response and Beacon frames sent by the GO.
Roughly validate the IEs and save some information for use in our own
IEs. p2p_extract_wfd_properties and p2p_device_validate_conn_wfd are
being moved unchanged to be usable in p2p_group_event without forward
declarations and to be next to p2p_build_wfd_ie.
Make the WSC IE processing and writing more self-contained (i.e. so that
it can be more easily moved to a separate file if desired) by using the
new ap_write_extra_ies() mechanism.
Pass the string IEs from the incoming STA association frames to
the user in the AP event data. I drop
ap_event_station_added_data.rsn_ie because that probably wasn't
going to ever be useful and the RSN IE is included in the .assoc_ies
array in any case.
Since GET_STATION (and in turn GetDiagnostics) gets the most
current station info this attribute serves as a better indication
of the current signal strength. In addition full mac cards don't
appear to always have the average attribute.
No instances of this macro now exist. If future instances crop up, the
better approach would be to use pragma directives to quiet such warnings
and allow static analysis to catch any issues.
Expanded packets with a 0 vendor id need to be treated just like
non-expanded ones. This led to very nasty looking if statements
throughout this function. Fix that by introducing a nested function
to take care of the response type normalization. This also allows us to
drop uninitialized_var usage.
Expanded Nak packet contains (possibly multiple) 8 byte chunks that
contain the type (1 byte, always '254') vendor-id (3 bytes) and
vendor-type (4) bytes.
Unfortunately the current logic was reading the vendor-id at the wrong
offset (0 instead of 1) and so the extracted vendor-type was incorrect.

If we received a Nak or an Expanded Nak packet, the intent was to print
our own method type. Instead we tried to print the Nak type contents.
Fix that by always passing in our method info to eap_type_to_str.

The '__' prefix is meant for private, semi-private,
inner implementation or otherwise special APIs that
are typically exposed in a header. In the case of watchlist, these
functions were static and do not fit the above description. Remove the
__ prefix accordingly.
Process output was being duplicated when -v was used. This was
due to both stderr and stdout being appended to the write_fd list
as well as stderr being set to stdout in the Popen call.
To fix this only stdout should be appended to the write_fd list,
but then there comes a problem with closing the streams. stdout
cannot be closed, so instead it is special cased. A new
verbose boolean was added to Process which, if True, will
cause any output to be written to stdout explicitly.
The Namespace class was never being removed when tests finished.
This is fixed by unreffing the hwsim internal _radio object which
both cleans up the radio and allows the Namespace to be removed.
This moves all the de-init code into kill(), which fixes a few
reference issues causing processes to hang around longer than
desired. If the process terminates on its own and/or the last
reference is lost __del__ will kill the process and clean up.
There were a few issues with the cleanup of Hostapd. First the
process was only being killed, which did not actually remove
the process from the list.
In addition, with EAP-SIM/AKA tests, hostapd created sim_db
unix socket files which it does not clean up.
This is somewhat of an open issue/TODO but for now this avoids
the exception caused by trying to remove a radio that has been
moved to a namespace. Once a radio is moved hwsim loses that phy
and can no longer interact with it. This causes the Destroy()
method call to fail.
A cleanup parameter was added to __init__ which can be used
by processes which create any additional files or require more
a custom cleanup routine. Some additional house keeping was
done to make Process cleanup more robust.
Though multi-test processes seemed like a good idea in terms of
efficiency, the additional code/special cases was not worth it
for the only two multi-test processes (dbus/haveged). Intead this
concept was removed completely and TestContext/Namespaces will
now start all processes for each individual test. This also is
fair to all tests as a previous failed test could end up bleeding
into future tests.
The cls object is part of the unittest framework and its lifespan
is out of test-runner's control. Setting objects into the cls
object sometimes keeps those objects around longer than desired.
Its best to unset anything set in cls when the test is tore down.
Printing out processes was done manually but instead we can
make Process printing extendable by adding its own __str__
method. This now will print if the process is a multi-test
process as well.
Output files in namespaces were not handled differently and would
end up overwriting/duplicating files from the root namespace. These
are now named /tmp/<process>-<namespace>-out.
The process class was quite hard to understand, and somewhat
fragile when multiple output options were needed like verbose
and logging, and in some cases even an additional output file.
To make things simpler we can have all processes output to a
temporary file (/tmp/<name>-out) and set a GLib IO watch on
that file. When the IO watch callback fires any additional
files (stdout, log files, output files) can be written to.
For wait=True processes we do not use an IO watch, but do
the same thing once the process exits, write to any additional
output files using the process output we already have.
