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.

8f946511c9 hwsim tests: Reset at the end of a test
Resetting at the beginning causes the reset logging/tracing
data to leak from the previous test into the next, and the
last one being missed at all - reset at the end of each run
instead. Also reset before all tests just in case running a
test actually crashed the python script.

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.

Instead of re-implementing a command-line parser, use the

Also, --help now works, and if a test module/test name is
given that doesn't exist, the valid list is printed.

392e68e81f Set GTK rekey offload information after initial group key handshake
The GTK rekey offload information was sent to the driver immediately
after the 4-way handshake which ended up being before the initial group
key exchange in the case of WPA (v1). This could result in even that
initial GTK handshake being offloaded and wpa_supplicant being left in
WPA_GROUP_HANDSHAKE state. Fix this by postponing the operation to
happen only after the full set of initial EAPOL-Key exchanges have been
completed (i.e., in the existing location for WPA2 and a after the group
key handshake for WPA).

731ca6364e Update regulatory change to all virtual interface for the phy
wpas_p2p_setup_channels function uses the per interface information
(wpa_s->hw.modes) for setting up the available channel list for P2P
operation, but if a separate P2P interface is used (e.g., p2p0 on
Android), the wpa_s instance for that interface may not get an updated
channel list. This can result in some operations, like "P2P_SET
disallow_freq", using old channel list information (e.g., world roaming
information with passive-scan/no-ibss flags) which was initialized
during the start-up. This could result in P2P functionality using
conflicting or obsolete channel information.

To resolve this issue, update channel list information on regulatory
change events to all of the virtual interfaces sharing the same phy for
which the event is received.

5afaa067d9 hostapd: Allow per-BSS (vif) configuration files
This provides a new option for configuring multiple virtual interfaces
(BSS) that share a single radio. The new command line parameter
-b<phyname>:<config file name> is used to define one or more virtual
interfaces for each PHY. The first such entry for a new PHY is used to
initialize the interface structure and all consecutive parameters that
have the same PHY name will be added as virtual BSS entries to that
interface. The radio parameters in the configuration files have to be
identical.

This can be used as an alternative for the bss=<ifname> separator and
multiple BSSes in a single configuration file design while still
allowing hostapd to control the PHY (struct hostapd_iface) as a group of
virtual interfaces (struct hostapd_data) so that common radio operations
like OLBC detection and HT40 co-ex scans can be done only once per real
radio.
