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.
Expanded packets with a 0 vendor id need to be treated just like
non-expanded ones. This led to very nasty looking if statements
throughout this function. Fix that by introducing a nested function
to take care of the response type normalization. This also allows us to
drop uninitialized_var usage.
Expanded Nak packet contains (possibly multiple) 8 byte chunks that
contain the type (1 byte, always '254') vendor-id (3 bytes) and
vendor-type (4) bytes.
Unfortunately the current logic was reading the vendor-id at the wrong
offset (0 instead of 1) and so the extracted vendor-type was incorrect.
Fixes: 17c569ba4c ("eap: Add authenticator method logic and API")
If we received a Nak or an Expanded Nak packet, the intent was to print
our own method type. Instead we tried to print the Nak type contents.
Fix that by always passing in our method info to eap_type_to_str.

The '__' prefix is meant for private, semi-private,
inner implementation or otherwise special APIs that
are typically exposed in a header. In the case of watchlist, these
functions were static and do not fit the above description. Remove the
__ prefix accordingly.
Process output was being duplicated when -v was used. This was
due to both stderr and stdout being appended to the write_fd list
as well as stderr being set to stdout in the Popen call.
To fix this only stdout should be appended to the write_fd list,
but then there comes a problem with closing the streams. stdout
cannot be closed, so instead it is special cased. A new
verbose boolean was added to Process which, if True, will
cause any output to be written to stdout explicitly.
The Namespace class was never being removed when tests finished.
This is fixed by unreffing the hwsim internal _radio object which
both cleans up the radio and allows the Namespace to be removed.
This moves all the de-init code into kill(), which fixes a few
reference issues causing processes to hang around longer than
desired. If the process terminates on its own and/or the last
reference is lost __del__ will kill the process and clean up.
There were a few issues with the cleanup of Hostapd. First the
process was only being killed, which did not actually remove
the process from the list.
In addition, with EAP-SIM/AKA tests, hostapd created sim_db
unix socket files which it does not clean up.
