The cls object is part of the unittest framework and its lifespan
is out of test-runner's control. Setting objects into the cls
object sometimes keeps those objects around longer than desired.
Its best to unset anything set in cls when the test is tore down.
This test fails randomly, and it appears to be due to excessive
scanning. Historically most autotests start a dbus scan right
away. The problem is that most likely a periodic scan is already
ongoing, meaning the dbus scan gets queued. If a Connect() call
comes in (which it always does), the dbus scan gets delayed and will
trigger once connected, at a time the test is not expecting. This
can cause problems with any assumed timing as well as offchannel
frames.
This patch removes the explicit DBus scanning and instead uses
scan_if_needed with get_ordered_networks. The 'all_blacklisted_test'
was also modified to wait for scanning to complete after failing
to connect to all BSS's. This lets all the networks fully come
up (after being blocked by hwsim) and appear in scan results.
Every single roaming test had one of two problems with watching the
state change between roaming --> connected. Either the test used
wait_for_object_condition to wait for 'connected' which could allow
other states in between. Or it simply used an assert. The assert
wouldn't allow other state changes, but at the cost of potentially
failing due to IWD not having made it to the 'connected' state yet.
Now we have wait_for_object_change which takes two conditions:
initial (from_str) and expected (to_str). This API will not allow
any other conditions except these, and will wait for the expected
condition before continuing. This allows roaming test to reliably
wait for the roaming --> connected state change.
This is similar to wait_for_object_condition, but will not allow
any intermediate state changes between the initial and expected
conditions. This is useful for roaming tests when the expected
state change is 'connected' --> 'roaming' with no changes in
between.
This test occationally failed due to a badly timed DBus scan
triggering right when hwsim tried sending out the spoofed frame.
This caused mac80211_hwsim to reject CMD_FRAME when the timing
was just right.
Rather than always starting a DBus scan we can rely on periodic
scans and only DBus scan if there are no networks in IWD's list.
A scanning check was also added prior to sending out the frame
and if true we wait for not scanning. This is more paranoia than
anything.
Sometimes scan results can come in with a MAC address which
should be in the first index of addrs[] (42:xx:xx:xx:xx:xx).
This causes a failure to lookup the radio path.
There was also a failure path added if the radio cannot be
found rather than rely on DBus to fail with a None path.
The arguments to SendFrame were also changed to use the
ByteArray DBus type rather than python's internal bytearray.
This shouldn't have any effect, but its more consistent with
how DBus arguments should be used.
After recent changes fixing wait_for_object_condition it was accidentally
made to only work with classes, not other types of objects. Instead
create a minimal class to hold _wait_timed_out so it doesnt rely on
'obj' holding the boolean.
The testAPRoam autotest was silently failing on my machine until I
realized that my distribution hostapd (Arch Linux) is not built with
CONFIG_WNM_AP=y. Indeed, it is also disabled by default in upstream
hostapd. This resulted in the send_bss_transition() function of
hostapd.py silently failing. With this change, throw an exception in
case the BSS_TM_REQ command does not succeed to hopefully save others
the time of debugging this problem.
After the test-runner re-write many tests were left with
stale options that are no longer used at all. These were
periodically getting removed as changes were made to
individual tests, but its apparent now that a tree wide
removal was needed.
There were some major problems related to logging and process
output. Tests which required output from start_process would
break if used with '--log/--verbose'. This is because we relied
on 'communicate' to retrieve the process output, but Popen does
not store process output when stdout/stderr are anything other
than PIPE.
Intead, in the case of logging or outfiles, we can simply read
from the file we just wrote to.
For an explicit --verbose application we must handle things
slightly different. A keyword argument was added to Process,
'need_out' which will ensure the process output is kept
regardless of --log or --verbose.
Now a user should be able to use --log/--verbose without any
tests failing.
After the re-write this was broken and not noticed until
recently. The issue appeared to be that the GLib timeout
callback retained no context of local variables. Previously
_wait_timed_out was set as a class variable, but this was
removed so multiple IWD instances could work. Without
_wait_timed_out being a class variable the GLib timeout
setting it had no effect on the wait loop.
To fix this we can set _wait_timed_out on the object being
passed in. This is preserved in the GLib timeout callback
and setting it gets honored in the wait loop.
Tests netconfig with a static configuration, as well as tests ACD
functionality.
The test has two IWD radios which will eventually use the same IP.
One is configured statically, one will receive the IP via DHCP.
The static client sets its IP first and begins using it. Then the
DHCP client is started. Since ACD in a DHCP client is configured
to use its address indefinitely, the static client *should* give
up its address.
Certain classes were still using the default namespace. This
didn't matter yet since testAP was the only test using namespaces,
and the AP interface was the only one being used.
For an IWD station on a separate namespace all objects need to
be accessable, so the namespace is passed along to those as needed.
Due to timing this test sometimes does not pass because it was
just asserting on the device state rather than waiting for a
change. This generally worked but not always.
Both these tests create many radios which sometimes causes timing
problems when hwsim is running. Since hwsim is not required for
these tests we can disable it and increase test reliability.
When network namespaces are introduced there may be multiple
IWD class instances. This makes IWD.get_instance ambiguous
when namespaces are involved. iwd.py has been refactored to
not use IWD.get_instance, but testutil still needs it since
its purely based off interface names. Rather than remove it
and modify every test to pass the IWD object we can just
maintain the existing behavior for only the root namespace.
The agent path was generated based on the current time which
sometimes yielded duplicate paths if agents were created quickly
after one another. Instead a simple iterator removes any chance
of a duplicate path.
If running multiple tests testNetconfig would fail due to the
hardcoded wln0 in the dhcpd.conf file. dhcpd can actually start
by passing in the interface to the run command rather than
inside the config file.
The existing AP tests needed to be modified to start IWD from
python since the DHCP test uses a different main.conf.
Also removed some stale hw.conf options that are no longer used.
If the caller specifies the number of devices only return that many.
Some sub-tests may only need a subset of the total number of devices
for the test. If the number of devices expected is less than the total
being returned, python would throw an exception.
If a test does not need any hostapd instances but still loads
hostapd.py for some reason we want to gracefully throw an
exception rather than fail in some other manor.
Add the new wpas.Wpas class roughly based on hostapd.HostapdCLI but only
adding methods for the P2P-related stuff.
Adding "wpa_supplicant" to -v will enable output from the wpa_supplicant
process to be printed and "wpa_supplicant-dbg" will make it more verbose
("wpa_supplicant" is not needed because it seems to be automatically
enabled because of the glob matching in ctx.is_verbose)
The host systems configuration directories for IWD/EAD were
being mounted in the virtual machine. This required that the
host create these directories before hand. Instead we can
just set up the system and IWD/EAD to use directories in /tmp
that we create when we start the VM. This avoids the need for
any host configuration.
This module is essentially a heavily stripped down version of iwd.py
to work with EAD. Class names were changed to match EAD but basically
the EAD, Adapter, and AdapterList classes map 1:1 to IWD, Device, and
DeviceList.
This is somewhat of a hack, but the IWDDBusAbstract is a very
convenient abstraction to DBus objects. The only piece that restricts
it to IWD is the hardcoded IWD_SERVICE. Instead we can pass in a
keyword argument which defaults to IWD_SERVICE. That way other modules
(like EAD) can utilize this abstraction with their own service simply
by changing that service argument.
The interface was hard coded to wln0 which works when running single
tests but not when running multiple. Instead use the actual ifname
that hostapd is using.
Tests that DHCP using IWD's internal netconfig functions properly.
The actual IP address assignment is not verified, but since IWD does
not signal the connection as successful unless DHCP succeeds we
can assume it was successful by checking that the device is connected.
The process of actually starting dhcpd and configuring the interfaces
is quite simple so it was left in the autotest itself. If (or when)
more tests require IP capabilities (p2p, FILS, etc) this could be
moved into test-runner itself and be made common. The reason I did not
put it in there now is a) because this is the only test and b) more
complex DHCP cases are likely to develop and may require more than this
simplistic setup (like multiple APs/interfaces)
The AdHoc functionality in iwd.py was not consistent at all with
how all the other classes worked (my bad). Instead we can create
a very simple AdHocDevice class which inherits all the DBus magic
in the IWDDBusAbstract class.
Many tests waited on the network object 'connected' property after
issuing a Connect command. This is not correct as 'connected' is
set quite early in the connection process. The correct way of doing
this is waiting for the device state to change to connected.
This common code was replaced, hopefully putting to rest any random
failures that happen occasionally.
Some cleanup code got removed by mistake which cleared out any
hwsim rules before the next subtest. Without this the second test
would end up getting erroneous signal strength numbers in the scan
results causing a failure.
This got added in the re-write but a __del__ method was also
added to the Rule class as well. This caused problems if hwsim
cleaned up since it removed the rules, which caused each rule
to call __del__. Since the rule had already been removed there
was no longer a DBus interface which raised an exception.
Before the re-write there was interesting escapes being used for
set_neighbor. Curiously now hostapd fails to set the neighbor due
to these escapes so they have been removed.
Switched around hwsim rules with the IWD initializer to avoid
IWD periodically scanning before hwsim rules are in place. Removed
some unneeded code during teardown.
Changed to wait for DeviceState instead of network object as well
as moved hwsim rules ahead of the IWD initializer to avoid IWD
scanning before the rules are fully in place.
This test occationally failed, and it uses the old style of waiting
for connected on the network object instead of the device object.
The hwsim rule was also moved ahead of the IWD() initializer which
ensures that IWD doesn't scan before the rule can be set/processed.
This test occationally fails due to no hwsim rules. Basically we
were just expecting iwd to connect to one of 3 access points but
the ranking was equal, so it chose the first in the scan list.
Now a signal strength is assigned to each AP to steer IWD into
connecting to the expected AP.
As with other tests, wait on device state instead of the network
object. The connectivity test was also changed to not check for
group traffic since AP does not negotiate the IGTK at this time.
There were a number of fixes here. The waits were changed to wait
on the device state instead of the network state and hwsim rules
were removed after the test as to not interfere with future tests.
One of the rules was setting the signal to -10000 wich was causing
the ranking to be zero.
Updated testFT-SAE-roam to use the TestContext APIs as well as
fixed the failure which was introduced after requiring stricter
AKM logic for SAE networks. The new failure was due to the hostapd
config not including the standard SAE AKM which is actually
required by the spec.
Slower systems may not be able to make some timeouts that tests
mandated. All timeouts were increased significantly to allow tests
to pass on slow systems.
It is not safe to assume that the python dbus implementation will
wait for a method to return. The documentation says this with
respect to reply_handler/error_handler:
"If both are None, the implementation may request that no reply is sent"
To stay on the safe side we should always include the error/reply
handlers and wait for the operation to complete.
test-runner now supports interface name replacement inside hostapd
config files. Since a given test configuration doesn't know what
interface names there will be $ifaceN can be specified instead e.g.
rsn_preauth_interfaces=$iface0 $iface1
The $ifaceN values will be replace with actual interface names when
the test is started.
This patch also removes ctrl_interface inside the hostapd config
files as this is no longer required.
This test was unreliable since it was assuming a periodic scan would
happen at just the right time. Instead since we are expecting autoconnect
we can just wait for DeviceState.connected then after we are connected
verify the network was correct.
This test was never 100% reliable, and after the test-runner re-write
it became extremely unreliable. The issue came down to the very common
block of code thats present in many tests where we wait for obj.scanning
then not obj.scanning. This is fine when a dbus scan() is explicitly
done before, otherwise it could lead to problems. Without a dbus scan
explicitly called we are assuming a periodic scan will happen. If it
already happen the initial wait for obj.scanning will never return and
time out.
This probably needs to be changed in several tests, but for this specific
case we can remove the waits completely. Since
check_autoconnect_hidden_network has a 30 second wait on
DeviceState.connected this will ultimately time out if anything goes
wrong. There isn't any great reason to wait for scanning (for this test
specifically).
A minor style change was also made when initializing IWD. The values
passed in this test are now the default, so no arguments need to be
passed.
iwd.py was updated to use the TestContext APIs to start/stop
IWD. This makes the process managment consistent between starting
IWD from test-runner or from the IWD() constructor.
The psk agent is now tracked, and destroyed upon __del__. This is
to fix issues where a test throws an exception and never
unregisters the agent, causing future tests to fail.
The configuration directory was also chaged to /tmp by
default. This was done since all tests which used this used /tmp
anyways.
The GLib mainloop was removed, and instead put into test-runner
itself. Now any mainloop operations can use ctx.mainloop instead
Before hostapd was initialized using the wiphy_map which has now
gone away. Instead we have a global config module which contains
a single 'ctx'. This is the centeral store for all test information.
This patch converts hostapd.py to lookup instances by already
initialized Hostapd object. The interface parameter was removed
since all tests have been converted to use config= instead.
In addition HostapdCLI was changed to allow no parameters if there
is only a single hostapd instance.
This patch completely re-writes test-runner in Python. This was done
because the existing C test-runner had some clunky work arounds and
maintaining or adding new features was starting to become a huge pain.
There were a few aspects of test-runner which continually had to
be dealt with when adding any new functionality:
* Argument parsing: Adding new arguments to test-runner wasn't so
bad, but if you wanted those arguments passed into the VM it
became a huge pain. Arguments needed to be parsed, then re-formatted
into the qemu command line, then re-parsed in a special order
(backwards) once in the VM. The burden for adding new arguments was
quite high so it was avoided (at least by me) at all costs.
* The separation between C and Python: The tests are all written in
python, but the executables, radios, and interfaces were all created
from C. The way we solved this was by encoding the require info as
environment variables, then parsing those from Python. It worked,
but it was, again, a huge pain.
* Process management: It started with all processes being launched
from C, but eventually tests required the ability to start IWD, or
kill hostapd ungracefully in order to test certain functionality.
Since the processes were tracked in C, Python had no way of
signalling that it killed a process and when it started one C had
no idea. This was mitigated (basically by killall), but it was
no where close to an elegant solution.
Re-writing test-runner in python solves all these problems and will
be much easier to maintain.
* Argument parsing: Now all arguments are forwarded automatically
to the VM. The ArgParse library takes care of parsing and each
argument is stored in a dictionary.
* Separation between C and Python: No more C, so no more separation.
* Process management: Python will now manage all processes. This
allows a test to kill, restart, or start a new process and not
have to remember the PID or to kill it after the test.
There are a few more important aspects of the python implementation
that should now be considered when writing new tests:
* The IWD constructor now has different default arugments. IWD
will always be started unless specified and the configuration
directory will always be /tmp
* Any non *.py file in the test directory will be copied to /tmp.
This avoids the need for 'tmpfs_extra_stuff' completely.
* ctrl_interface will automatically be appended to every hostapd
config. There is no need to include this in a config file from
now on.
* Test cleanup is extremely important. All tests get run in the
same interpreter now and the tests themselves are actually loaded
as python modules. This means e.g. if you somehow kept a reference
to IWD() any subsequent tests would not start since IWD is still
running.
* For debugging, the test context can be printed which shows running
processes, radios, and interfaces.
Three non-native python modules were used: PrettyTable, colored, and
pyroute2
$ pip3 install prettytable
$ pip3 install termcolor
$ pip3 install pyroute2
The tests basically remained the same with a few minor changes.
The wiphy_map and in turn hostapd_map are no longer used. This
was already partially converted a long time ago when the 'config'
parameter was added to HostapdCLI. This patch fully converts all
autotests to use 'config' rather than looking up by interface.
Some test scripts were named 'test.py' which was fine before but
the new rewrite actually loads each python test as a module. The
name 'test' is too ambiguous and causes issues due to a native
python module with the same name. All of these files were
renamed to 'connection_test.py'.
First, looking for DeviceState.connected gives a much better indication
if we are actually connected vs the connected property on the network
object. Second, its good practice to also check that hostapd sees that
the station is connected.
Restarting hostapd from python was actually leaking memory and
causing the hostapd object to stay referenced in python. The
GLib timeout in wait_for_event was the ultimate cause, but this
had no come to light because no tests restarted hostapd then
used wait_for_event.
In addition, any use of wait_for_event after a restart would
cause an exception because the event socket was never re-attached
after hostapd restarted.
Now we properly clean up the timeout in wait_for_event and
re-initialize the hostapd object on restart.
Many tests force a reauth after the initial connection. When the tests
were written there was no way of ensuring the reauth completed except
waiting (IWD.wait()). Now we can wait for hostapd events in the tests,
which is faster and more reliable than busy waiting.
This test was not reliably passing. Busy waiting is not really reliable,
but in this specific case its really the only option as the blacklist
must expire based on time.
In certain cases the autoconnect portion of each subtest was connecting
to the network so fast that the check for obj.scanning was never successful
since IWD was already connected (and in turn not scanning). Since the
autoconnect path will wait for the device to be connected there really isn't
a reason to wait for any scanning conditions. The normal connect path does
need to wait for scanning though, and for this we can now use the new
scan_if_needed parameter to get_ordered_networks.
There is a very common block of code inside many autotests
which goes something like:
device.scan()
condition = 'obj.scanning'
wd.wait_for_object_condition(device, condition)
condition = 'not obj.scanning'
wd.wait_for_object_condition(device, condition)
network = device.get_ordered_network('an-ssid')
When you see the same pattern in nearly all the tests this shows
we need a helper. Basic autotests which merely check that a
connection succeeded should not need to write the same code again
and again. This code ends up being copy-pasted which can lead to
bugs.
There is also a code pattern which attempts to get ordered
networks, and if this fails it scans and tries again. This, while
not optimal, does prevent unneeded scanning by first checking if
any networks already exist.
This patch solves both the code reuse issue as well as the recovery
if get_ordered_network(s) fails. A new optional parameter was
added to get_ordered_network(s) which is False by default. If True
get_ordered_network(s) will perform a scan if the initial call
yields no networks. Tests will now be able to simply call
get_ordered_network(s) without performing a scan before hand.
These values were meant only to force IWD's BSS preference but
since the RSSI's were so low in some cases this caused a roam
immediately after connecting. This patch changes the RSSI values
to prevent a roam from happening.
'Connected' property of the network object is set before the connection
attempt is made and does not indicate a connection success. Therefore,
use device status property to identify the connection status of the device.
This test made it past the initial refactor to use HostapdCLI with the
'config' parameter. This avoids the need to iterate the hostapd map in
the actual test.
This test merely verifies hostapd receieved our measurement reports
and verified they were valid. Hostapd does not verify the actual
beacon report body. Really, the only way to test this is on an
actual network which makes these requests.
Hostapd has a feature where you can connect to its control socket and
receive events it generates. Currently we only send commands via this
socket.
First we open the socket (/var/run/hostapd/<iface>) and send the
ATTACH command. This tells hostapd we are ready and after this any
events will be sent over this socket.
A new API, wait_for_event, was added which takes an event string and
waits for some timeout. The glib event loop has been integrated into
this, though its not technically async since we are selecting over a
socket which blocks. To mitigate this a small timeout was chosen for
each select call and then wrapped in a while loop which waits for the
full timeout.
Its difficult to know 100%, but this random test failures appeared
to be caused by two issues. One was that get_ordered_network is being
checked for None, when it was returning a zero length array. Because
of this the scanning block was never executed in any cases. This was
fixed in the previous commit. The other issue was the disconnect at
the start of the tests. The disconnect will cause all pending scans
to cancel, which appeared to cause the scanning block below to be
skipped over quickly if the timing was right. Then, afterwards,
getting a single network failed because scanning was not complete.
If no networks are found, return None rather than an empty
array. This is easier to check by the caller (and was assumed
in some cases). Also add an exception to get_ordered_network
if no network is found.
If the config file passed in is not found we would continue and
eventually something else would fail. Instead immediately raise an
exception to be more clear on what is actually failing.
This autotest was manually creating the .known_network.freq file so
the UUID needed to be manually generated and updated for the test
to function correctly.
This is merely an empty test that can act as a sandbox for the new
--shell command. It was not named with 'test' so that autotesting
will skip it.
This test is not very useful for virtual hardware testing
(mac80211_hwsim), but very useful for USB/PCI passthrough. When
setup correctly, you can now pass through a single device and test
against real networks with a minimal kernel.
Doing this scan causes issues in the test. Like with other autoconnect
tests we can just use the fact that IWD will always be doing a periodic
scan during start up, so we only need to wait for that to finish before
querying the network list.
Initially the solution to copying files to .hotspot was to use the
existing copy_to_storage, but allow full directory copying. Doing it
this way does not allow us to copy single files into .hotspot which
makes it difficult to test single configurations in several consecutive
tests.
This adds a new API, copy_to_hotspot, where a single hotspot config
can be provided. clear_storage was also modified to clear out the
.hotspot directory in addition to the regular storage directory.
This removes all the duplicated code where the interfaces are iterated
and the radio/hostapd instances are created. Instead the two new APIs
are used to get each instance, e.g.:
hapd = HostapdCLI(config='ssid.conf')
radio = hwsim.get_radio('radX')
There is a common interface lookup in many tests in order to initialize
the HostapdCLI object e.g.:
for intf in hostapd_map.values():
if intf.config == 'ssidOWE.conf':
hapd = HostapdCLI(intf)
break
Instead of having to do this in every test, HostapdCLI will now
optionally take a config file (config=<file>). The interface object
will still be prefered (i.e. supplying an interface will not even
check the config file) as to not break existing tests. But if only
a config file is supplied the lookup is done internally.
There are some tests that do still need the interface, as they do
an interface lookup to initialize both hostapd and hwsim at the
same time.
The start_ap method was raising potential dbus errors before converting
them to an IWD error type. This is due to dbus.Set() not taking an error
handler. The only way to address this is to catch the error, convert it
and raise the converted error.
Running autotests with native hardware will not work on tests which
depend on the hwsim python API (since hwsim will not be running).
For these tests, it will now be required that they specify:
needs_hwsim=1
This allows the test to be skipped when running with native hardware
rather than the test failing with a python exception.
This new test was merged during the time when testutil was not working
properly, so it was never verified to work with respect to testutil
(testing for 'connected' has always worked).
Since testFILS has 2 hostapd interfaces test_interface_connected was
defaulting to the incorrect interface for the SHA384 test. Now, the
explicit interfaces are passed in when checking for connectivity.
Don't use del wd to dereference the IWD instance at the end of the function
where it has been defined in the first place as at this point wd is about
to have its reference count decreased anyway (the variable's scope is
ending) so it's pointless (but didn't hurt).
Relying on the __del__ destructor to kill the IWD process in those tests
it has been started in the constructor is a bit of a hack in the first
place, because the destructor is called on garbage collection and even
through CPython does this on the refcount reaching 0, this is not
documented and there's no guideline on when it should happen or if it
should happen at all. So it could be argued that we should keep the del
wd statemenets to be able to easily replace all of them with a call to a
new method. But most of them are not placed so that they're guaranteed
to happen on test success or failure. It would probably be easier to do
this and other housekeeping in a base class and make the tests its
subclasses. Also some of these tests don't really need to launch iwd
themselves, since IWD now tracks changes in the known network files I
think IWD only really needs to be killed between tests when main.conf
changes.
In the tests that only want to iterate over the hostapd interfaces,
simplify the pattern of walking through the whole wiphy_map tree by
instead using the hostapd_map variable which is already filtered to only
contain hostapd interfaces.
For the interface connectivity tests obtain the lists of interfaces in
use directly from the IWD class, which has the current list from DBus
properties.
The hostapd_map dictionary is indexed by the interface name so there's
no point iterating over it to find that entry whose name matches, we can
look up by the name directly. Simplify code.
In the test utilties updated the wiphy_map struct built from the
TEST_WIPHY_LIST variable to parse the new format and to use a new
structure where each wiphy is a namedtuple and each interface under it
also contains a reference to that wiphy. The 'use' field is now
assigned to the wiphy instead of to the interface.
The AdHoc methods used to miss the change in properties
on AdHoc interface. To address the race condition, we
subscribe 'PropertiesChanged' signal first and then do
GetAll properties call. This way we are not missing
'PropertiesChanged' signal in between these calls.
Previously, the WPS tests have shared a single instance of iwd
among themselves. This approach didn’t allow to identify which
tests have passed and which failed. The new solution makes WPS
tests independent from each other by creating a new instance
of iwd for each one of them.
The simplest way to test this was to create a new AP, where
max_num_sta=1. This only allows a single STA to connect to this AP.
We connect a device to this AP, then try and connect with another.
This results in hostapd failing with DENIED_NO_MORE_STAS, which will
cause a temporary blacklist. We can then disconnect both devices,
and reconnect the device that previously got denied. If it connects
then we know the blacklist only persisted for that earlier connection.
This is a VERY simple test for HT/VHT. Since there are so many potential
options in the IE this really just tests that drops in RSSI will cause
IWD to choose a different BSS, even if that means choosing HT over VHT,
or even basic rates over HT/VHT.
SAE has a clogging test which requires 4 radios to all simultaneously
connect. All the other tests are only using one of these radios, so
in these tests we explicitly disconnect these devices preventing them
from autoconnecting.
Since the EAP-PWD fragmentation test uses group 19 there is test
coverage there for that group. This changes connection_test to use
group 20 instead of 19.
When using --valgrind, you must also use --verbose iwd, and, depending
on the tests you may also need to include pytests in the verbose flag.
Since anyone using --valgrind definitely wants to see valgrind info
printed they should not need to enable verbose printing. Also, manually
parsing valgrind prints with IWD prints mixed throughout is a nightmare
even for a single test.
This patch uses valgrind's --log-file flag, which is directed to
/tmp/valgrind.log. After the tests runs we can print out this file.
This is a helper/shortcut to get_ordered_networks (plural). In nearly
all the autotests we had (roughly) the same block of code:
ordered_network = get_ordered_networks()[0]
self.assertNotEqual(ordered_network, None)
self.assertEqual(ordered_network.name, "someSsid")
Rather than having to do this, we can simplify and just have a single
call to get_ordered_network, which takes the SSID. If the SSID is not
found, we raise an exception. This avoids needing both asserts since
we are guarenteed that the return is valid and the SSID matches.
This also avoids possible issues with multiple networks showing up in
the GetOrderedNetworks call. Eventually test-runner will support running
tests on real wireless hardware, so its possible we could pick up
unexpected networks in the scan.
At some point a stray ';' got added into an autotest in a section
of code that is heavily copy pasted. So in turn nearly all the autotests
have this stray ';' after list_devices (and a few in other places).
testWPA was not verifying connectivity between the two interfaces. Funny
enough, doing this resulted in the same problems that adhoc had where
we were setting the connection as complete before the gtk/igtk were set.
This is fixed now so we can now use testutil in this test.
Curiously this test started failing. The problem was incorrect KC/SRES
values in the sim.db file. I noticed no direct changes to this file,
but changes inside ofono, phonesim, and hostapd could have potentially
caused this.
This test was copied from testFT-PSK-roam, but for SAE. The test behaves
as follows:
- Connect to SAE network (full authentication)
- Fast transition to another SAE AP
- Fast transition to a PSK/WPA2 AP
This is a temporary fix to address the recent split of
the Device interface. This patch contains a workaround that
re-enables the auto-tests while the test framework is being
reworked to satisfy the need of the new API and should not
be considered as a permanent solution.
Fixed two issues:
1. There is no longer a dbus exception when switching to AP mode when
connected in station mode so that assert was removed.
2. After the device/station change the timing must have changed, causing
autoconnect to take over before an explicit connect call. Added a
psk provisioning file that disables autoconnect.
Make sure stop_ap is called on success and on failure in both tests so
that one can succeed after the other has failed. Also make sure to move
both interfaces out of autoconnect state.
