not set and must not be used. Report internal error instead to avoid use

Add test-tls program that can be used for fuzzing the internal TLS
client and server implementations. This tool can write client or server
messages into a file as an initialization step and for the fuzzing step,
that file (with potential modifications) can be used to replace the
internally generated message contents.
The TEST_FUZZ=y build parameter is used to make a special build where a
hardcoded random number generator and hardcoded timestamp are used to
force deterministic behavior for the TLS operations.

conn->cred might be NULL here, so check for that explicitly before
checking whether conn->cred->cert_probe is set. This fixes a potential
NULL pointer dereference when going through peer certificates with
event_cb functionality enabled.

The result of reading non blocked empty stream is different between
python2 and 3. The python2 sends "[Errno 11] Resource temporarily
unavailable" exception. The python3 could read "None" without
exception, so handle this "None" case as well.

p2p->find_start timer was updated on each p2p_find call irrespective of
p2p_find being successful/failed/rejected. For cases where p2p_find was
in progress/pending, another call to p2p_find would be rejected but
p2p->find_start timer would still be updated.
p2p->find_start is maintained in wpa_supplicant to reject the kernel
scan entries before the p2p->find_start time. In above scenario, some of
the scan entries could be discarded even if the Probe Respons frame(s)
were received during the last scan/p2p_find.
This commit changes this to update the p2p->find_start timer only when
call to p2p_find is successful, i.e., a new scan is actually started.

Do not use a separate enum for MBO WNM-Notification Request frame

The previously used value 2 was already assigned for another purpose

In recent Debian versions, ebtables is an alias managed by
the alternatives(8) mechanism. This means /usr/sbin/ebtables
is a symlink to /etc/alternatives/ebtables, which in turn
links to the real binary.
As we mount a tmpfs over /etc, we cannot access this.
Fix this by bind-mounting the real /etc to /tmp/etc and
adding a symlink from /etc/alternatives to this.

Add a test that drops the authentication frame, so that
hostapd thinks the station is unknown, and then sends one

This command has now been extended to include PMK for offload needs, so

We do not need such payload in the acknowledgment, so adding it uses
resources unnecessarily. Furthermore, the original request can include
key material (e.g., NL80211_ATTR_PMK). libnl does not explicitly clear
this received message buffer and it would be inconvenient for
wpa_supplicant/hostapd to try to clear it with the current libnl design
where a duplicated buffer is actually passed to the callback. This means
that keys might be left unnecessarily in heap memory. Avoid this by
requesting the kernel not to copy back the request payload.

If telnetd is installed and --telnet <port> is passed on the
vm-run.sh command line, start a telnet server (directly connected
to bash, no login) inside the VM(s) to be able to look into them
when something is wrong. Use a user network in qemu with a single
host forward from the specified port for this, listening only on
'localhost'.
Please note that this provides unauthenticated access to the guest
system from anything that can open a TCP connection on the host system.
The guess system does have access to reading all files on the host that
the user account running kvm has access to (and even write access if the
default ROTAG ,readonly parameter is cleared). In other words, this
option should not be used on any multiuser systems where kvm is run
under user accounts that are not dedicated for testing purposes (i.e.,
do not have access to any files that should not be readable to
everyone).
This needs CONFIG_VIRTIO_NET=y in the guest kernel.
For parallel-vm.py, the --telnet argument specifies the base port
and each VM index (0, 1, ...) is added to it.

Recently, qemu/seabios grew an annoying console/terminal reset,
which also causes my terminal to be left in a state where long
lines don't work well and less gets confused because of this.
