This driver event was used separately for some Action frames, but all
the driver wrappers converted to this from information that would have
been enough to indicate an EVENT_RX_MGMT event. In addition, the
received event was then converted back to a full IEEE 802.11 management
frame for processing in most cases. This is unnecessary complexity, so
get rid of the extra path and use EVENT_RX_MGMT for Action frames as
well as other management frame subtypes.

Previously, WPS credential provisioning removed duplicated network

leaving the old entry behind can result in connectibity issues (e.g.,
with 4-way handshake failing due to use of the old PSK). Fix this by
allowing the old network entry to be removed even if the keys

An INTERFACE_DISABLED event received on an interface that is

In such a case, if the interface was dynamically added remove it, and
if not, remove all the network blocks that are temporary, assuming
that if needed a new session will be started by an external entity.
The use case was triggering rfkill (both SW and HW). This case popped up

On scan results event if a concurrent P2P scan was triggered previously,

been canceled).

allows more options for the peer to use channels, e.g., if the local
device is not aware of its current location and has marked most channels
to require passive scanning.

The new p2p_no_go_freq frequency range list (comma-separated list of
min-max frequency ranges in MHz) can now be used to configure channels
on which the local device is not allowed to operate as a GO, but on
which that device can be a P2P Client. These channels are left in the
P2P Channel List in GO Negotiation to allow the peer device to select
one of the channels for the cases where the peer becomes the GO. The
local end will remove these channels from consideration if it becomes
the GO.

wpa_s->conf cannot be NULL because wpa_supplicant_init_iface() would not
allow wpa_supplicant_add_iface() to return wpa_s instance in such state.

Trying to access the SIM card details without checking if the eap_proxy
layer has been initialized can results in a crash. Address this by
sending the request for the IMSI through eapol_supp_sm.c which can
verify that eap_proxy has been initialized.

It is possible for there to be two pending off-channel TX frames, e.g.,
when two devices initiate GO Negotiation at more or less the same time.
This could result in the TX status report for the first frame clearing
wpa_s->pending_action_tx that included the newer frame that has not yet
been transmitted (i.e., is waiting to be sent out). Avoid losing that
frame by confirming that the TX status payload matches the pending frame
before clearing the pending frame and reporting the TX status callback.

DISCONNECT followed by ENABLE_NETWORK ended up starting a scan for a new
connection due to wpa_supplicant_enable_one_network() setting
wpa_s->reassociate = 1. This was done regardless of wpa_s->disconnected
being 1 which should imply that wpa_supplicant should not try to connect
before asked explicitly with REASSOCIATE or RECONNECT.
Fix this by making ENABLE_NETWORK setting of reassociate = 1 and
starting of scans for connection conditional on wpa_s->disconnected ==
0. This will make ENABLE_NETWORK trigger a connection only if
wpa_supplicant is already in a state where it would try to connect if
there are any enabled networks.

To disallow roaming when a scan request's results are read, callers
of the D-Bus Scan() method may add a new "AllowRoam" boolean key
to the scan options dictionary and set that key's value to FALSE.

If a scan is currently running and the scan interval is changed, a
second scan will be started before the current has finished. This will
in turn, if no networks are configured, cause wpa_s->state to be
forced to WPA_INACTIVE before the first scan has finished.

Need to use the pointer to the current ongoing query instead of matching
from the pending list based on the destination address so that we get

These operations can have conflicting offchannel requirements, so wait
with a new scan trigger until a pending GAS query has been completed.

Offchannel operations needed for a GAS query can conflict with ongoing
scan/connection progress, so delay GAS queries if such an operation is
in progress on the current interface or any virtual interface sharing
the same radio.

It would be possible to issue another GAS query when a previous one is
still in progress and this could result in conflicting offchannel
operations. Prevent that by delaying GAS query initiation until the
previous operation has been completed.

This makes it less likely to forget WPS single-channel scan optimization

The new configuration parameter external_sim=<0/1> can now be used to
configure wpa_supplicant to use external SIM/USIM processing (e.g., GSM
authentication for EAP-SIM or UMTS authentication for EAP-AKA). The
requests and responses for such operations are sent over the ctrl_iface
CTRL-REQ-SIM and CTRL-RSP-SIM commands similarly to the existing
password query mechanism.
Changes to the EAP methods to use this new mechanism will be added in
separate commits.

This is needed to avoid issues with control interface commands that
could request BSS list during an eapol_test run. wpa_cli tries to update
its internal BSS list and that could trigger eapol_test crashes without
this.

This is what the original implementation did years ago, but the move to
using separate control interface backends re-ordered the implementation
to process EAPOL notification first. Use a registered timeout to allow
the ctrl_iface response to be sent out first to get somewhat faster
response time and to avoid pending operations that could result in
ctrl_iface response and unsolicited event messages from getting mixed
up.
