c64b6f62cd tests: Use python selector in the parallel-vm.py main loop
This gets rid of the loop that was polling for things to do every 0.25
seconds and instead, reacts to any data from VMs as soon as it becomes
available. This avoids unnecessary operations when no new data is
available and avoids unnecessary waits when new data becomes available
more quickly.

179279eb34 tests: Move VM starting delay control into parallel-vm.py
This is more efficient since we can now start only the necessary number
of VMs instead of always forcing all VMs to start with one second delay.
This can also control the starting delay by keeping at most two VMs
starting at a time instead of using the hardcoded one second wait for
each consecutive VM.

9dc07a1d55 tests: Fix 'unexpected exit' detection in parallel-vm.py
Now that parallel-vm.py is actually stopping VMs as soon as they are not
needed for retries, it is not really an unexpected exit to see a VM exit
while test cases remain in the queue as long as at least that many VMs
remain running. Get rid of confusing 'unexpected exit' status from the
UI in such cases.

4aaddecdd8 tests: Handle test retries through the same queue
This removes the separate rerun step from the parallel-vm.py processing
and instead, simply requeues the failed test cases into the same queue
that is used for the initial run. This is simpler and more efficient
since reruns start as soon as any VM is ready for processing them
instead of having to wait for all VMs to complete the first round.
Furthermore, this allows VMs to be stopped sooner when no more test
cases remain and that is helpful especially with the time travel patches
that make the wait-for-next-test step in the VM use all available CPU.

2080f4c779 tests: uml: Request non-raw serial ports
When the serial ports are set into raw mode on stdio (fd:0,fd:1)
then Ctrl-C is sort of passed through, but not effective. Request
non-raw mode to avoid that and let us cancel test execution with
Ctrl-C properly (both in parallel-vm.py and vm-run.sh cases).

Note that this requires a currently out-of-tree patch, but so
does the virtual time. If the patch is not applied, the command
line argument is ignored.

e5a410f472 tests: Make /etc/alternatives work in VM
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.

e339511007 tests: Optionally start telnet server inside VMs
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.

79bbafd78c tests: Store the correct PID in hostapd-test.pid file
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.

c6ba02154e tests: Enable dynamic debugging for mac80211_hwsim
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.

8b19401679 tests: Comment out CONFIG_DEBUG_KOBJECT_RELEASE from default config
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.

56dfb604a4 Revert "tests: vm: Output everything on console"
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.
