Jouni Malinen 9b850799c1 Fix scan-cache-clearing operation to avoid unnecessary cases
wpa_drv_scan() success case was supposed to clear
wpa_s->clear_driver_scan_cache, not params->only_new_results (which
would do nothing here).

Jouni Malinen 2f30cac36f Avoid unnecessary key clearing operations
Track set_key operations per-key index and clear keys on disconnection
only if the key was set (or may have been set which is the case for the
first operation after wpa_supplicant start).

Jouni Malinen 949938aadf Ask driver to report only new scan results if requested
If the BSS table within wpa_supplicant is flushed, request the driver to
flush its own scan result table during the next scan. This can avoid
unexpected old BSS entries showing up after BSS_FLUSH or FLUSH command
in cases where the driver may maintain its internal cache of scan
results (e.g., cfg80211 BSS table persists at least for 15 seconds).

In addition to doing this automatically on BSS_FLUSH/FLUSH, a new SCAN
command argument, only_new=1, can be used to request a manual scan
request to do same. Though, it should be noted that this maintains the
BSS table within wpa_supplicant. BSS_FLUSH followed by SCAN command can
be used to clear all BSS entries from both the driver and
wpa_supplicant.

Jouni Malinen 5890fa81d8 WPS: Fix clear-from-timeout handling to avoid race condition
The 100 ms timeout to clear WPS state after EAP-Failure has been
received worked otherwise fine, but it opened a race condition on
another WPS operation starting within that wait. If that happens, the
timeout will cancel that new operation unexpectedly. Fix this by
cancelling the timeout from wpas_clear_wps().

Jouni Malinen 4848a38d85 Get rid of duplicated cipher suite and AKM definitions
WPA_CIPHER_* and CIPHER_* are used for the exact same set of cipher
suites with the main difference being that the WPA_CIPHER_* version is
suitable to be used as a bitfield. Similarly, WPA_KEY_MGMT_* and
KEY_MGMT_* have similar design for AKMs. There is no need to maintain
two separate copies of the definitions since the bitfield compatible
version can be used for both needs. Get rid of the CIPHER_* and
KEY_MGMT_* versions to clean up the implementation by getting rid of
unnecessary mapping functions.

The option of handling upper layer P2P management operations within the

but this has not really happened and there is no clear sign of this
being needed in the near term either. This functionality has not been
completed and it is certainly not being kept up-to-date or tested. As
such, it is best to remove it for now and if this or something similar
is needed in the future, it can be brought back once a clear need for it
has been demonstrated first.

This driver event was used separately for some Action frames, but all

received event was then converted back to a full IEEE 802.11 management
frame for processing in most cases. This is unnecessary complexity, so

well as other management frame subtypes.

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
(passphrase, PSK, WEP keys) are different.

Ilan Peer 6f72577f29 P2P: Handle INTERFACE_DISABLED event on a P2P GO interface
An INTERFACE_DISABLED event received on an interface that is
currently operating a P2P GO means that the group session ended.
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
as part of a testing cycle, where after a toggle in the rfkill state,
the result was that the interface was not deleted, but on the other hand
the wpa_supplicant did not configure the kernel to re-start the AP
functionality again.

Loic Poulain 1245503188 Restore scan_req if sta scan is rescheduled in the scan results event
On scan results event if a concurrent P2P scan was triggered previously,
scan results processing is canceled, p2p_find executed, and a new sta
scan is triggered (pending scan). However, this new sta scan does not
restore the scan_req value of the previous scan (whose scan result has
been canceled).

If we are currently connected to an AP and use ap_scan=2, the new
triggered scan will cause an associtation-without-scan in
wpa_supplicant_scan:
(ap_scan == 2 & scan_req != MANUAL_SCAN_REQ)
	=> wpa_supplicant_assoc_try()
causing an association error and a disconnection.

This patch fixes this issue by restoring the previous scan_req value.

However, it was not used when inviting a peer to re-invoke a persistent

Jithu Jance f86d282f43 Handle legacy scan interruption of sched_scan/PNO
While starting from PNO start context, the scheduled scan was not
setting the flag wpa_s->scanning. This was resulting in the subsequent
SCAN command to proceed further and send command to nl80211/cfg80211.
The expected behavior of cancelling sched_scan was not happening here.

While sched_scan is in progress and a legacy scan comes on the
cli/socket, the sched_scan is cancelled and normal scan is allowed to
continue. However, sometimes sched_scan cancelled event comes a bit
delayed and we will send out the scan command before the wpa_s->scanning
is cleared. Instead, reschedule the incoming scan req if the
wpa_s->scanning shows that it is still in progress.

Vinay Krishna Eranna 731ca6364e Update regulatory change to all virtual interface for the phy
wpas_p2p_setup_channels function uses the per interface information
(wpa_s->hw.modes) for setting up the available channel list for P2P
operation, but if a separate P2P interface is used (e.g., p2p0 on
Android), the wpa_s instance for that interface may not get an updated
channel list. This can result in some operations, like "P2P_SET
disallow_freq", using old channel list information (e.g., world roaming
information with passive-scan/no-ibss flags) which was initialized
during the start-up. This could result in P2P functionality using
conflicting or obsolete channel information.

To resolve this issue, update channel list information on regulatory
change events to all of the virtual interfaces sharing the same phy for
which the event is received.

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

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.

Response that does not include P2P IE. Do not update the IEs in this BSS
entry to avoid such loss of information that may be needed for P2P
operations to determine group information.

Jouni Malinen adeb4f59a2 P2P: Make sure wait for the first client gets stopped
If a group was removed before the wait for the first client had timed
out and the client had not yet connected, p2p_go_wait_client could have
been left set and with that, scan operations could be unnecessarily
delayed. This fixes some undesired delays from commit
c1c0b35fea.

Deepthi Gowri acdd0fc84f P2P: Clear p2p_group_formation and p2p_in_provisioning on group removal
Commit 41f853235f extends group formation
timeout for the first data connection to complete and resets
p2p_go_group_formation_completed flag due to which p2p_in_provisioning
and p2p_group_formation flags are not cleared when
wpas_group_formation_completed() is called. This can result in both
station scan and p2p_find failures in the case where separate P2P group
interface is not used and the client does not complete 4-way handshake.
Fix this by clearing p2p_group_formation and p2p_in_provisioning when
such a P2P group is deleted.

Add Extended Capabilities element to association request only if the AP
included this element in Beacon/Probe Response frames. This is a
workaround to address interoperability issues with some older APs that
do not seem to be able to handle Extended Capabilities element in
(Re)Association Request frames.

Jouni Malinen ea61aa1de1 Add no_ctrl_interface config param to clear ctrl_interface
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.

Jouni Malinen 25b65a142d Make sure updated BSS entry does not get added twice to the list
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.

Jouni Malinen a3cbf82e6d Fix possible freed-memory use in BSS table updates
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.

Jouni Malinen bbc6c729a5 P2P: Use group formation timeout on persistent group GO
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
P2P_MAX_INITIAL_CONN_WAIT_GO_REINVOKE (15) seconds.
