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.
The log dir was never being cleaned out prior to a new logging
test run. This could leave old stale files around. Note that this
will remove any past log files so if you need them, you want to
make a copy before running test-runner with --log again.
This test fails randomly, and it appears to be due to excessive
scanning. Historically most autotests start a dbus scan right
away. The problem is that most likely a periodic scan is already
ongoing, meaning the dbus scan gets queued. If a Connect() call
comes in (which it always does), the dbus scan gets delayed and will
trigger once connected, at a time the test is not expecting. This
can cause problems with any assumed timing as well as offchannel
frames.
This patch removes the explicit DBus scanning and instead uses
scan_if_needed with get_ordered_networks. The 'all_blacklisted_test'
was also modified to wait for scanning to complete after failing
to connect to all BSS's. This lets all the networks fully come
up (after being blocked by hwsim) and appear in scan results.
When using iwd.conf:[General].EnableNetworkConfiguration=true, it is not
possible to configure systemd.network:[Network].MulticastDNS= as
systemd-networkd considers the link to be unmanaged. This patch allows
iwd to configure that setting on systemd-resolved directly.
