We use the mtime on the network profile as the 'Last Connected Time'.
When we update any property and sync the file to disk, the mtime was not
preserved (since we were creating a new temporary file instead of
modifying the old one). This led to LastConnectedTime property change
being emitted / updated incorrectly when a writable property on the
KnownNetwork interface was updated.
Our design preference is to not call any callbacks in the _free/_destroy
method of a class (with the exception of explicit destroy callbacks
provided, if any).
Invoking the callback in this case was unnecessary: wsc_dbus_free was
already replying to pending connect / cancel messages. The only other
thing the callback would attempt to do is to set station back into
autoconnect mode. This was unnecessary as well since the netdev is
already down.
This change removes the callback invocation. Since wsc_enrollee_destroy
is now just calling wsc_enrollee_free, remove this from the API and
expose wsc_enrollee_free instead.
Split the WSC D-Bus interface class (struct wsc) into a base class
common to station mode and P2P mode (struct wsc_dbus) and station-
specific logic like scanning, saving the credentials as a known network
and triggering the station-mode connection (struct wsc_station_dbus).
Make the base class and its utilities public in wsc.h for P2P use.
Create struct wsc_enrollee which is allocated with wsc_enrollee_new,
taking a done callback as a parameter. The callback is always
called so there's no need for a separate destroy callback. The object
only lives until the done callback happens so wsc_enrollee_cancel/destroy
can only be used before this.
Looks like the rest of the file is simplified thanks to this.
This new API is independent of netdev.c and allows actually
unregistering from receiving notifications of frames, although with some
quirks. The current API only allowed the callback for a registration to
be forgotten but our process and/or the kernel would still be woken up
when matching frames were received because the kernel had no frame
unregister call. In the new API you can supply a group-id paramter when
registering frames. If it is non-zero the frame_watch_group_remove() call
can be used to remove all frame registrations that had a given group-id
by closing the netlink socket on which the notifications would be
received. This means though that it's a slightly costly operation.
The file is named frame-xchg.c because I'm thinking of also adding
utilities for sending frames and waiting for one of a number of replies
and handling the acked/un-acked information.
There's are two changes to the example raw data in m8_encrypted_settings,
one is to change the Network Index value to 1 and the other is to drop
the Network Key Index attribute:
Network Index R Deprecated - use fixed value 1 for
backwards compatibility.
Network Key O Deprecated. Only included by WSC 1.0
Index devices. Ignored by WSC 2.0 or newer
devices.
Instead of taking the credentials from wsc object directly, have the
caller pass these in. This makes it more consistent with how the
done_cb was done.
Split the interface-specific logic from the core WSC logic. The core
WSC code is the part that we can re-use between P2P and station and
doesn't include the D-Bus code, scanning for the target BSS or the
attempt to make a station mode connection.
Allow netdev_create_from_genl callers to draw a random or non-random MAC
and pass it in the parameter instead of a bool to tell us to generating
the MAC locally. In P2P we are generating the MAC some time before
creating the netdev in order to pass it to the peer during negotiation.
Some test cases require (at least with recent hostapd versions) a
stand alone radius server. This is done using driver=none in the
hostapd config file. For this use case hostapd does not need any
radio since its not doing anything wireless related.
Now inside the hw.conf file, under the HOSTAPD group, you can
specify a config file as the value to 'radius_server' key. This
config file will be used without any associated radio when hostapd
is started.
Some server implementation don't seem to provide the valid compound MACs.
In the meantime, iwd will ignore the invalid Crypto-Binding TLVs as their
usage is optional.
There are wiki's floating around, but I have consolidated the steps for
USB passthrough into our internal docs.

The intent was to check for the presence of the add_domain_name
operation, not add_dns operation.

It seems that the kernel uses -EOPNOTSUPP if the change_station
operation is not implemented by the driver. However, some drivers do
implement change_station and choose to report -ENOTSUPP instead of
-EOPNOTSUPP.
To add to the confusion, EOPNOTSUPP and -ENOTSUPP are the same on some
systems (e.g. Gentoo). Be paranoid and allow both errors to be ignored
when sending CMD_SET_STATION.

The first if case should be -10950, not 10950. Without the negative
this first case would get hit every time since signal strength values
are always negative.
The Crypto Binding TLV is used to ensure that the EAP peer and the
EAP server participated in both the inner and the outer EAP
authentications of a PEAP authentication by cryptographically associating
the phase 1 and phase 2 authentications.
The usage of Crypto-Binding in PEAPv0 is optional and is triggered by
the reception of the Crypto-Binding TLV from the server.
The handler for EAP Extensions has been modified to support multiple
TLV types instead of the single Result TLV. This will allow to handle
the other TLVs such as Crypto-Binding TLV.
There are some server implementations that send requests that are
not "Password" but still want us send password. This commit modify
the behavior to send a warning and still try to auth with password.
This makes me able to auth with server in my school which sends
"Enter Aruba Login".
wpa_supplicant does not check if it is "Password".
The kernel uses -EOPNOTSUPP in the case of change_station operation not
being provided. On most systems -EOPNOTSUPP is defined to be the same
as -ENOTSUPP, but seemingly not all systems.
