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.
WSC EAP method always results in failure, even if successful. Failed
eapol_sm sessions are auto-cleaned, so there's no need to do this
explicitly. Also eapol_exit() will clean up any left-over sessions, so
drop this to make the code a bit simpler.
If the extended feature for CQM levels was not supported no CQM
registration would happen, not even for a single level. This
caused IWD to completely lose the ability to roam since it would
only get notified when the kernel was disconnecting, around -90
dBm, not giving IWD enough time to roam.
Instead if the extended feature is not supported we can still
register for the event, just without multiple signal levels.
This fixes up a previous commit which breaks iwctl. The
check was added to satisfy static analysis but it ended
up preventing iwctl from starting. In this case mkdir
can fail (e.g. if the directory already exists) and only
if it fails should the history be read. Otherwise a
successful mkdir return indicates the history folder is
new and there is no reason to try reading it.
There is no functional change here but checking the return
value makes static analysis much happier. Checking the
return and setting the default inside the if clause is also
consistent with how IWD does it many other places.
Dbus should be started as a multi-test process from the
TestContext, which leaves the dbus address file around for
the full test run. For Namespaces dbus-daemon should be
closed when the Namespace closes.
Handle situations where the BSS we're trying to connect to is no longer
in the kernel scan result cache. Normally, the kernel will re-scan the
target frequency if this happens on the CMD_CONNECT path, and retry the
connection.
Unfortunately, CMD_AUTHENTICATE path used for WPA3, OWE and FILS does
not have this scanning behavior. CMD_AUTHENTICATE simply fails with
a -ENOENT error. Work around this by trying a limited scan of the
target frequency and re-trying CMD_AUTHENTICATE once.
Every single roaming test had one of two problems with watching the
state change between roaming --> connected. Either the test used
wait_for_object_condition to wait for 'connected' which could allow
other states in between. Or it simply used an assert. The assert
wouldn't allow other state changes, but at the cost of potentially
failing due to IWD not having made it to the 'connected' state yet.
Now we have wait_for_object_change which takes two conditions:
initial (from_str) and expected (to_str). This API will not allow
any other conditions except these, and will wait for the expected
condition before continuing. This allows roaming test to reliably
wait for the roaming --> connected state change.
This is similar to wait_for_object_condition, but will not allow
any intermediate state changes between the initial and expected
conditions. This is useful for roaming tests when the expected
state change is 'connected' --> 'roaming' with no changes in
between.
