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.

The new configuration parameter external_sim=<0/1> can now be used to

This is what the original implementation did years ago, but the move to
using separate control interface backends re-ordered the implementation

wpa_config_write_key_mgmt has a buffer size of 50. This is not enough
to fit the longest case. I used a network with "WPA-PSK WPA-EAP
WPA-NONE" and CONFIG_IEEE80211R=y + CONFIG_IEEE80211W=y to produce
a string longer than 50 chars. Increase the buffer size to 100 to
prevent truncated output.
Truncated output is not the only problem. If the buffer end is
reached when adding certain key mgmt types the function does not
return immediately. This leaves pos > end. When a second os_sprintf
is called the calculation of end - pos yields a large positive
number for buffer size. End result is a write beyond the buffer end.
Fix this by bailing out if buffer end is reached.

P2P-GROUP-STARTED event depends on having enough information about the
group available. To avoid incomplete information from being delivered to
upper layers, do not accept scan results without P2P IE (e.g., from a
non-P2P scan) for P2P client association process. This can be of use for
some join-a-group cases where non-P2P scans have generated the BSS entry
for the GO.

P2P IE may be available from a Beacon frame from a GO even if we have

displaying incomplete group information.

This fixes some P2P-join-a-group cases where GO may have been discovered
based on passive scan or non-P2P scan. P2P IEs may have been received

This could happen when non-P2P station interface runs a scan without P2P

If a group was removed before the wait for the first client had timed

Commit 41f853235f extends group formation
timeout for the first data connection to complete and resets

no_ctrl_interface parsing was declared within ifdef CONFIG_CTRL_IFACE

Signed-hostap: Jouni Malinen <j@w1.fi>
This can be used to override previously set ctrl_interface value in a
way that clears the variable to NULL instead of empty string. The only
real use case for this is to disable per-interface ctrl_interface from
the additional control file (-I<file>) in case ctrl_interface was set in
the main configuration file. It should be noted that zero-length
ctrl_interface parameter can be used to initiate some control interface
backends, so simpler designs were not available for this.
The format of the new parameter is not exactly cleanest due to
configuration file parsing assumptions. For example:
ctrl_interface=....
no_ctrl_interface=
would end up with ctrl_interface=NULL.

When the BSS table is being updated based on new scan results, a BSS
entry could end up getting added into last_scan_res list multiple times
if the scan results from the driver includes duplicated values. This
should not happen with driver_nl80211.c since it filter outs duplicates,
but in theory, other driver wrappers could indicate such scan results.
Anyway, it is safer to make sure this cannot happen by explicitly
verifying the last_scan_res list before adding an updated BSS entry
there. A duplicated entry in the list could potentially result in freed
memory being used if there is large enough number of BSSes in the scan
results to cause removal of old BSS entries.
Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
If there are large number of BSSes in the scan results, BSS table update
could have added a BSS entry to the last_scan_res in a case where that
BSS entry got just deleted. This would happen only if there are more
than bss_max_count (by default 200) BSSes and if at least bss_max_count
of those BSSes are known (match a configured network). In such a case,
wpa_bss_add() could end up allocating a new BSS entry and return a
pointer to that entry even if it was the one that ended up getting freed
to keep the BSS table length within the limit. This could result in
freed memory being used and the process crashing (likely with segfault)
when trying to access information from that BSS entry.
Fix the issue by removing the oldest BSS entry before linking the new
entry to the table. This makes sure the newly added entry will never get
picked up as the one to be deleted immediately.

Previously, GO considered the group to be fully re-invoked after
starting beaconing on successful invitation exchange. This would leave
the group running until idle timeout (which may not be enabled) or
explicit removal if the client fails to connect for any reason. Since
the client is expected to connect immediately after the invitation
exchange that ends with status=0 (i.e., either client initiated the
exchange or it responded with success), extend group formation timeout
to cover that period until the first successfully completed data
connection. This allows the GO to remove the group automatically if the
client devices does not connect within

If wpa_supplicant ctrl_iface clients are misbehaving and refusing to
read replies or event messages from wpa_supplicant, the single socket
used in wpa_supplicant to send messages can reach the maximum send
buffer limit. When that happens, no more responses to any client can be
sent. Work around this by closed and reopening the socket in case such a
failure state is detected. This is obviously not desirable since it
breaks existing connected sockets, but is needed to avoid leaving
wpa_supplicant completely unable to respond to any client. Cleaner fix
for this may require more considerable changes in the ctrl_iface design
to move to connection oriented design to allow each client to be handled
separately and unreachability to be detected more reliably.
