fdbc092389 hwsim tests: Add build script
This is easier than to copy/paste from the README. We may
want to extend it later to change the .config for some
common differences between systems (e.g., libnl/libbfd).

a5d7da3fd3 hwsim tests: Prefill database in VM tests
In some cases, e.g., with the VM tests if the VM crashes, it
can be useful to know which tests should have run but didn't
(or didn't finish). In order to catch these more easily, add
an option to prefill the database with all tests at the very
beginning of the testing (in a new NOTRUN state) and use the
option in the VM tests.

4a1b8901ab hwsim tests: Refactor test results reporting
Refactor the test reporting to treat the different results
(success/skip/failure) identically. This makes the timing
seem a bit longer, but cleans up the code which will allow
for adding more checks (e.g., on the captured data files)
later.

1cd3eae362 hwsim tests: Allow setting KERNEL and KVMARGS
Rather than just having KERNELDIR, allow setting KERNEL directly.
Also remove the -s option that prevents running multiple machines
at the same time, but add a KVMARGS= variable that can be used to
restore that if needed.

c092d83e26 P2P: Clear pending group formation data on group removal
It was possible for the wpa_s->show_group_started and wpa_s->go_params
to be left set when a P2P group was removed before group formation had
completed. In case a separate P2P group interface was not used, this
could rsult in all future scans using the hardcoded DIRECT-* SSID and as
such, not find the network they were trying to find. Fix this by
clearing these P2P parameters on group removal.

813d4bac5a DFS: Add support for multi-BSS
If radar was detected single BSS is notified about it. This caused only
that single BSS to be stopped and restarted. However, due to nl80211
interface combinations the BSS was not started on a new channel and
other BSSes remained operating on the old channel.

The downside is that hostapd_disable_iface() causes deauth frames to be
sent. This is undesired but on the other hand it doesn't make sense to
create workarounds that imitate CSA's 'block tx'. For proper Tx
quiescing CSA should be properly implemented.

970d3b096f hwsim tests: Add scripts to run in a VM
Instead of running on the host, it can be useful to run in a
VM, particularly to test kernel rather than userspace changes,
so add a few scripts that allow doing so easily.

The basic idea is that the VM kernel is the same architecture
as the host kernel, so the host's root filesystem can be used
(in read-only mode) to run everything. Only a log filesystem
is mounted read-write and will get all the test output.

The kernel console output is collected to a special 'console'
file in the logs directory and kernel crashes are detected.

958bf1ba39 hwsim tests: Move logging into timestamped subdirectory
Instead of logging many files called "<timestamp>-*", log into
a new "<timestamp>/*" in the logs/ subdirectory and only put
the last-debug file into logs/. If a LOGDIR is specified in the
environment, instead just put everything into that directory
(so the caller should make sure to give it a timestamp or so)
and skip the creation of last-debug entirely.

Also clean up a bit and pass the LOGDIR from run-all.sh to
start.sh rather than having start.sh create the timestamp and
run-all.sh detect the latest one when having run start.sh.

435e37df7c hwsim tests: Allow run-tests.py to start tracing
In order to get tracing per test, allow run-tests.py to start
and stop tracing per test case. This is implemented using a
python 'with' context so it starts/stops automatically at the
right spots.

Instead of starting global tracing, also use it from run-all.sh
and put the trace files into the log dir.

Note that this only works right if you use a separate log dir
for all test runs as the trace files aren't timestamped.
