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.

We capture the dmesg that contains everything, but if a test
causes a kernel crash we will miss all logging at higher levels
like debug. Change the printk level to catch all of that too.

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 is useful for now since the IPv6 support for proxyarp is not yet
included in the upstream kernel. This allows the IPv4 test cases to pass
with the current upstream kernel while allowing the IPv6 test cases to
report SKIP instead of FAIL.

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.

It looks like the 128M default memory size for the hwsim test setup was
