When we cancel a quick scan that has already been triggered, the
Scanning property is never reset to false. This doesn't fully reflect
the actual scanning state of the hardware since we don't (yet) abort
the scan, but at least corrects the public API behavior.
{Network} [/net/connman/iwd/0/7/73706733_psk] Connected = False
{Station} [/net/connman/iwd/0/7] Scanning = True
{Station} [/net/connman/iwd/0/7] State = connecting
{Station} [/net/connman/iwd/0/7] ConnectedNetwork =
/net/connman/iwd/0/7/73706733_psk
{Network} [/net/connman/iwd/0/7/73706733_psk] Connected = True
If IWD is connecting to a SAE/WPA3 BSS and Auth/Assoc commands
are not supported the only option is SAE offload. At this point
network_connect should have verified that the extended feature
for SAE offload exists so we can simply enable offload if these
commands are not supported.
SAE offload support requires some minor tweaks to CMD_CONNECT
as well as special checks once the connect event comes in. Since
at this point we are fully connected.
After adding network_bss_update, network now has a match_addr
queue function which can be used to replace an unneeded
l_queue_get_entries loop with l_queue_find.
This will swap out a scan_bss object with a duplicate that may
exist in a networks bss_list. The duplicate will be removed by
since the object is owned by station it is assumed that it will
be freed elsewhere.
If the hardware roams automatically we want to be sure to not
react to CQM events and attempt to roam/disconnect on our own.
Note: this is only important for very new kernels where CQM
events were recently added to brcmfmac.
Roaming on a full mac card is quite different than soft mac
and needs to be specially handled. The process starts with
the CMD_ROAM event, which tells us the driver is already
roamed and associated with a new AP. After this it expects
the 4-way handshake to be initiated. This in itself is quite
simple, the complexity comes with how this is piped into IWD.
After CMD_ROAM fires its assumed that a scan result is
available in the kernel, which is obtained using a newly
added scan API scan_get_firmware_scan. The only special
bit of this is that it does not 'schedule' a scan but simply
calls GET_SCAN. This is treated special and will not be
queued behind any other pending scan requests. This lets us
reuse some parsing code paths in scan and initialize a
scan_bss object which ultimately gets handed to station so
it can update connected_bss/bss_list.
For consistency station must also transition to a roaming state.
Since this roam is all handled by netdev two new events were
added, NETDEV_EVENT_ROAMING and NETDEV_EVENT_ROAMED. Both allow
station to transition between roaming/connected states, and ROAMED
provides station with the new scan_bss to replace connected_bss.
Adds support for getting firmware scan results from the kernel.
This is intended to be used after the firmware roamed automatically
and the scan result is require for handshake initialization.
The scan 'request' is competely separate from the normal scan
queue, though scan_results, scan_request, and the scan_context
are all used for consistency and code reuse.
Register P2P group's vendor IE writers using the new API to build and
attach the necessary P2P IE and WFD IEs to the (Re)Association Response,
Probe Response and Beacon frames sent by the GO.
Roughly validate the IEs and save some information for use in our own
IEs. p2p_extract_wfd_properties and p2p_device_validate_conn_wfd are
being moved unchanged to be usable in p2p_group_event without forward
declarations and to be next to p2p_build_wfd_ie.
Make the WSC IE processing and writing more self-contained (i.e. so that
it can be more easily moved to a separate file if desired) by using the
new ap_write_extra_ies() mechanism.
Pass the string IEs from the incoming STA association frames to
the user in the AP event data. I drop
ap_event_station_added_data.rsn_ie because that probably wasn't
going to ever be useful and the RSN IE is included in the .assoc_ies
array in any case.
Since GET_STATION (and in turn GetDiagnostics) gets the most
current station info this attribute serves as a better indication
of the current signal strength. In addition full mac cards don't
appear to always have the average attribute.
No instances of this macro now exist. If future instances crop up, the
better approach would be to use pragma directives to quiet such warnings
and allow static analysis to catch any issues.
