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.
Add a "psk" setting to allow the user to pass the binary PSK directly
instead of generating it from the passphrase and the SSID. In that case
we'll only send the PSK to WSC enrollees.
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.
