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.

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.

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.
Suppress this by suppressing all output from qemu before a new
magic string printed from inside.sh.

The hwsim's start.sh script spawns hostapd process using "sudo".
Since sudo forks a child process, $! holds the pid of sudo itself.
Fix that by storing the PID of the child process instead.
Since in VM "sudo" is replaced with a dummy script, pass an additional
argument to run-all.sh and start.sh scripts to indicate that they are
running inside a VM.
This is needed to fix ap_config_reload and ap_config_reload_file test
cases on some platforms where sudo is apparently not relaying the
signals properly.

mac80211_hwsim module typically dumps a lot of details into the kernel
message buffer. While it's probably okay in a dedicated VM, it's way too
chatty in other setups.
The kernel allows fine-tuning logging via the dynamic debugging
facility. Let's enable all logging locations in the mac80211_hwsim
module so that we don't loose debugging output when the kernel adopts
the dynamic debug mechanism for the driver.

This kernel debugging option adds multiple seconds of extra latency to
interface removal operations. While this can be worked around by
increasing timeouts in number of test cases, there does not seem to be
any clean way of working around this for PMKSA cacheching test with
per-STA VIFs (e.g., pmksa_cache_preauth_vlan_used_per_sta_vif).
To avoid unnecessary test failures, remove CONFIG_DEBUG_KOBJECT_RELEASE
from the default config. If someone wants to test with this kernel debug
option, it can be enabled for custom kernel builds while understanding
that it can result in false failure reports and significantly extended
time needed to complete full testing run.

This reverts commit be9fe3d8af. While I
did manage to complete multiple test runs without failures, it looks
like this change increases full test run duration by about 30 seconds
when using seven VMs. The most visible reason for that seems to be in
"breaking" active scanning quite frequently with the Probe Response
frame coming out about 40 ms (or more) after the Probe Request frame
which is long enough for the station to already have left the channel.
Since this logging change is not critical, it is simplest to revert it
for now rather than make changes to huge number of test cases to allow
more scan attempts to be performed before timing out.

Now that vm-run.sh supports a long list of test cases without crashing
the VM kernel, there is no need to use the "parallel-vm.py -1 1 <tests>"
workaround. Print the re-run example commands with vm-run.sh instead. In
addition, add the --long argument if it was specified for the test run
to avoid skipping test cases in the re-run case.

If /tmp has a relatively small size limit, or multiple people run the

This adds hwsim test ap_vlan_iface_cleanup_multibss. It connects two
stations in different BSS but the same hostapd process. First both
stations are in VLAN 1, then they get reauthenticated into VLAN 2. Due
to the ordering of the stations moving around, this test checks that
bridge and tagged interface referencing counting is done globally, such
that the tagged interface is not removed too early and no bridge is
left over.
