[PATCH 1/2] frame-xchg: Fix frame_watch_remove_by_handler for group 0
by Andrew Zaborowski
Don't match the default group's (group_id 0) wdev_id against the
provided wdev_id because the default group can be used on all wdevs and
its wdev_id is 0. Also match individual item's wdev_id in the group to
make up for this although it normally wouldn't matter.

[PATCH] scan: don't send the same scan request twice
by Alvin Šipraga
If start_scan_next_request() is called while a scan request
(NL80211_CMD_GET_SCAN) is still running, the same scan request will be
sent again by mistake. Add a check in the function to avoid sending a
request if one is already in progress.
This also fixes a crash that occurs if the following conditions are met:
- the duplicated request is the only request in the scan request
queue, and
- both scan requests fail with an error not EBUSY.
In this case, the first callback to scan_request_triggered() will delete
the request from the scan request queue. The second callback will find
an empty queue and consequently pass a NULL scan_request pointer to
scan_request_failed(), causing a segmentation fault.

Scanning while in AP mode
by Erik Botö
Hi,
I want to scan for networks while having an active AP. From what I
understand this can be achieved by using NL80211_SCAN_FLAG_AP.
The documentation for it say:
* @NL80211_SCAN_FLAG_AP: force a scan even if the interface is configured
* as AP and the beaconing has already been configured. This attribute is
* dangerous because will destroy stations performance as a lot of frames
* will be lost while scanning off-channel, therefore it must be used only
* when really needed
So I suppose it's not something that should be enabled by default, but
it would be useful to be able to start a scan with this if explicitly
requested.
My use case for this is initial device setup. A new device would be
configured to start up in AP-mode and a inital setup service would run
that e.g. a phone could connect to and be presented with a list of
found networks. Then a network can be selected and credentials setup,
then the device will shut down the AP and instead connect as a client
to the selected network. Like many IoT devices etc let's you do when
configuring.
What do you think, is it something that could fit into iwd or is there
some reasons to not support this?
Cheers,
Erik

[PATCH 1/2] anqp: refactor to use frame-xchg
by James Prestwood
The new frame-xchg module now handles a lot of what ANQP used to do. ANQP
now does not need to depend on nl80211/netdev for building and sending
frames. It also no longer needs any of the request lookups or frame
watches because frame-xchg filters this for us. The request queue did
need to remain in ANQP because station fires off ANQP requests all in
a row, and frame-xchg cannot handle this. Now ANQP just sends out the
first request, and queue's the rest. As the responses come in it will
send out the next frame in the queue until there are no more left.
The anqp_request API was changed to only return a bool, as well as
take the wdev_id rather than ifindex. Station was updated to remove
the 'pending' member since it was not actually used, as well as fix
a bug on the timeout path where the request queue would get popped
twice.
There is somewhat of a TODO that was overlooked initially with ANQP
and was realized when testing these patches. Since the network_info
depends on ANQP completing there is a race condition between scanning
finishing and being ready to connect to networks which require ANQP.
The autoconnect case does not have this issue, but explicit Dbus
connects do. In practice this may not matter since the user would have
to issue a connect at just the right time, but it could still happen.
This may need to be fixed in network where we see if there are any
pending ANQP requests before we return NotConfigured. If there are
pending requests we should wait for those, then attempt to connect.

[PATCH v2 1/2] netdev: unify ft/auth_proto authenticate builders
by James Prestwood
build_cmd_ft_authenticate and build_cmd_authenticate were virtually
identical. These have been unified into a single builder.
We were also incorrectly including ATTR_IE to every authenticate
command, which violates the spec for certain protocols, This was
removed and any auth protocols will now add any IEs that they require.

[PATCH] netdev: don't include ATTR_IE for SAE
by James Prestwood
The spec outlines what fields/elements can be included with different
auth types. For SAE only a few fields are allowed. IE's are not allowed
but were being included with CMD_AUTHENTICATE.
