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.

b0797ec955 tests: Suppress annoying console reset from VMs
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.

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.

23fcfd6004 tests: Allow passing more arguments to vm-run.sh
The script is currently limited by the maximum kernel command line
length and if that's exceeded the kernel panics at boot. Fix this by

680ce356c0 tests: Honor HWSIM_TEST_LOG_DIR variable in VM runs
If /tmp has a relatively small size limit, or multiple people run the
tests on the same machine, using the same output directory can easily
cause problems.

Make the test framework honor the new HWSIM_TEST_LOG_DIR environment
variable to make it easier to avoid those problems.

8412dd52d1 tests: Increase default VM memory from 128M to 192M
It looks like the 128M default memory size for the hwsim test setup was
not large enough to cover all the needs anymore. Some of the test cases
using tshark could hit OOM with that size. Increase the default
allocation to 192M to avoid this type of issues.

"parallel-vm.sh <number of VMs> [arguments..]" can now be used to run

Use a more robust design for collecting the gcov logs from the case
where test cases are run within a virtual machine. This generates a

lcov and gcov can easily find the matching source code and data files.
In addition, prepare the reports automatically at the end of the
vm-run.sh --codecov execution.

4ecf11c559 hwsim tests: Make channel configuration for VM tests easier
Add a CHANNELS configuration to the script running the VM
that can be added to the vm-config file to allow running
the tests with hwsim devices supporting more than a single
channel.

Eventually, with the (hopefully) upcoming dynamic work in
mac80211_hwsim, this might go away entirely, but for now
this allows testing more code paths.

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.
