There has been a desire to remove the ELL plugin dependency from
IWD which is the only consumer of the plugin API. This removes
the dependency and prepares the tree for converting the existing
ofono plugin into a regular module.
sim_hardcoded was removed completely. This was originall implemented
before full ofono support purely to test the IWD side of EAP-SIM/AKA.
Since the ofono plugin (module-to-be) is now fully implemented there
really isn't a need for sim_hardcoded.
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)
This is just a more concise/pythonic way of doing function arguments.
Since Process/start_process have basically the same argument names
we can simplify and use **kwargs which will pass the named arguments
directly to Process(). This also allows us to add arguments to Process
without touching start_process if we need.
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.
The Started property was being set in the Join IBSS callback which
isn't really when the IBSS has been started. The kernel automatically
scans for IBSS networks which takes some time. Its better to wait
on setting Started until we get the Join IBSS event.
Commit 1f910f84b4 ("eapol: Use eapol_start in authenticator mode too")
introduced the requirement that authentication eapol_sm objects also had
to be started via eapol_start. Adhoc was never updated to do that.
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.
For multi-bss networks its nice to know which BSS is being connected
to. The ranking can hint at it, but blacklisting or network capabilities
could effect which network is actually chosen. An explicit debug print
makes debugging much easier.
Again the hs->support_ip_allocation flag is used for two purposes here,
first the user signals whether to support this mechanism through this
flag, then it reads the flag to find out if an IP was allocated.
Support IP allocation during the 4-Way Handshake as defined in the P2P
spec. This is the supplicant side implementation.
The API requires the user to set hs->support_ip_allocation true before
eapol_start(). On HANDSHAKE_EVENT_COMPLETE, if this same flag is still
set, we've received the IP lease, the netmask and the authenticator's
IP from the authenticator and there's no need to start DHCP. If the
flag is cleared, the user needs to use DHCP.
Allow the possibility of becoming the Group-owner when we parse the GO
Negotiation Request, build GO Negotiation Response and parse the GO
Negotiation Confirmation, i.e. if we're responding to a negotiation
initiated by the peer after it needed to request user action.
Until now the code assumed we can't become the GO or we'd report error.

Add a utility to select random characters from the set defined in P2P
v1.7 Section 3.2.1. In this version the assumption is that we're only
actually using this for the two SSID characters.
explicit_bzero is used in src/ap.c since commit
d55e00b31d but src/missing.h is not
included, as a result build with uclibc fails on:
/srv/storage/autobuild/run/instance-1/output-1/host/lib/gcc/xtensa-buildroot-linux-uclibc/9.3.0/../../../../xtensa-buildroot-linux-uclibc/bin/ld: src/ap.o: in function `ap_probe_req_cb':
ap.c:(.text+0x23d8): undefined reference to `explicit_bzero'

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.
Removed test-runner.c, and renamed py_runner to test-runner. Removed
tools/test-runner from .gitignore.
This was done as a separate commit to avoid a nasty diff between the
existing test runner, and the new python version
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
