Marek Puzyniak 8a0f3bf613 AP: Fix checking if DFS is required
Sometimes function hostapd_is_dfs_required() returns -1 which indicates
that it was not possible to check if DFS was required. This happens for
channels from the 2.4 GHz band where DFS checking should not happen.
This can be fixed by returning DFS-not-required for mode different from
IEEE80211A and when DFS support is not available (ieee80211h not set).

Jouni Malinen d2c33b91ad Reduce the amount of time PTK/TPTK/GTK is kept in memory
Some of the buffers used to keep a copy of PTK/TPTK/GTK in the
supplicant implementation maintained a copy of the keys longer than
necessary. Clear these buffers to zero when the key is not needed
anymore to minimize the amount of time key material is kept in memory.

Jouni Malinen e47ee249bc l2_packet: Fix l2_packet_none (hostapd default)
The sample code here ended up trying to register an eloop socket with fd
== -1. This was not really ever supposed to be used, but it is now also
hitting an assert in eloop. Skip the unnecessary
eloop_register_read_sock() to avoid this.

This was causing issues for hostapd since CONFIG_L2_PACKET is not set by
default. If CONFIG_RSN_PREAUTH=y was not used for CONFIG_L2_PACKET was
not set in .config explicitly, the defaul use of l2_packet_none.c ended
up hitting the newly added assert() in eloop.

This was already done for the disconnect event, but
SME-in-wpa_supplicant case needs to do same with the deauth event to
avoid getting extra events during WPS disconnect-and-reconnect sequence.

Nirav Shah 0e0e1e564f P2P: Add retry mechanism for GO Negotiation Confirmation
wpa_supplicant now retries for P2P_GO_NEG_CNF_MAX_RETRY_COUNT times if
it doesn't receive acknowledgement for GO Negotiation Confirmation
frame. Currently, P2P_GO_NEG_CNF_MAX_RETRY_COUNT is set to 1.

While this is not strictly speaking following the P2P specification,
this can improve robustness of GO Negotiation in environments with
interference and also with peer devices that do not behave properly
(e.g., by not remaining awake on the negotiation channel through the
full GO Negotiation).

Jouni Malinen bb52293e71 OpenSSL: Detect and prevent TLS heartbeat attack
Some OpenSSL versions have vulnerability in TLS heartbeat request
processing. Check the processed message to determine if the attack has
been used and if so, do not send the response to the peer. This does not
prevent the buffer read overflow within OpenSSL, but this prevents the
attacker from receiving the information.

This change is an additional layer of protection if some yet to be
identified paths were to expose this OpenSSL vulnerability. However, the
way OpenSSL is used for EAP-TLS/TTLS/PEAP/FAST in hostapd/wpa_supplicant
was already rejecting the messages before the response goes out and as
such, this additional change is unlikely to be needed to avoid the
issue.

Sunil Dutt 96ecea5eb1 Pass TDLS peer capability information in tdls_mgmt
While framing the TDLS Setup Confirmation frame, the driver needs to
know if the TDLS peer is VHT/HT/WMM capable and thus shall construct the
VHT/HT operation / WMM parameter elements accordingly. Supplicant
determines if the TDLS peer is VHT/HT/WMM capable based on the presence
of the respective IEs in the received TDLS Setup Response frame.

The host driver should not need to parse the received TDLS Response
frame and thus, should be able to rely on the supplicant to indicate
the capability of the peer through additional flags while transmitting
the TDLS Setup Confirmation frame through tdls_mgmt operations.

Jouni Malinen 1b5df9e591 nl80211: Do not indicate scan started event on scan_for_auth
The scan_for_auth workaround for cfg80211 missing a BSS entry for the
target BSS during authentication uses a single channel scan controlled
within driver_nl80211.c. This operation does not indicate
EVENT_SCAN_RESULTS to the upper layer code. However, it did report
EVENT_SCAN_STARTED and this resulted in the radio work protection code
assuming that an external program triggered a scan, but that scan never
completed. This resulted in all new radio work items getting stuck
waiting for this scan to complete.

Fix this by handling the scan_for_auth situation consistently within
driver_nl80211.c by filtering both the EVENT_SCAN_STARTED and
EVENT_SCAN_RESULTS.

Jouni Malinen 49b74430d9 Fix HT40 co-ex scan for some pri/sec channel switches
Secondary channel was compared incorrectly (-4/4 vs. actual channel
number) which broke matching neighboring 40 MHz BSSes and only the
no-beacons-on-secondary-channel rule was applied in practice. Once
sec_chan was fixed, this triggered another issue in this function where
both rules to switch pri/sec channels could end up getting applied in a
way that effectively canceled the switch.

Jouni Malinen e8d70a739b nl80211: Hide deauth event due to forced deauth-during-auth
If NL80211_CMD_AUTHENTICATE fails due to exiting authentication, forced
deauthentication is used to clear cfg80211 start and a new
authentication command is retried. This resulted in an extra
disconnection event getting delivered to the core wpa_supplicant code
and that could end up confusing state there, e.g., by clearing
connection parameters like wpa_s->key_mgmt and preventing the following
association from reaching proper COMPLETED state with open networks.

Fix this by hiding the unnecessary disconnection event when using the

Simon Wunderlich 1d91f504e4 hostapd: Process management frames only once per BSS
At least in nl80211, broadcast management frames like Probe Request
frames, may be processed multiple times per BSS if multi-BSS is active
and NL80211_CMD_FRAME event is used to deliver them. In the case of
Probe Request frames, hostapd will create multiple redundant Probe
Response frames which are problematic when many BSS are on one channel.

This problem is caused by driver_nl80211 generating an event for
wpa_supplicant_event() for each BSS, and hostapd_mgmt_rx() calls
ieee802_11_mgmt() for each BSS, too.

Fix this by processing broadcast events only for the BSS the driver
intended to. The behavior is not changed for drivers not setting a BSS.

Jouni Malinen 390b92913a TLS testing: Allow hostapd to be used as a TLS testing tool
The internal TLS server implementation and RADIUS server implementation
in hostapd can be configured to allow EAP clients to be tested to
perform TLS validation steps correctly. This functionality is not
included in the default build; CONFIG_TESTING_OPTIONS=y in
hostapd/.config can be used to enable this.

When enabled, the RADIUS server will configure special TLS test modes
based on the received User-Name attribute value in this format:
<user>@test-tls-<id>.<rest-of-realm>. For example,
anonymous@test-tls-1.example.com. When this special format is used, TLS
test modes are enabled. For other cases, the RADIUS server works
normally.

The following TLS test cases are enabled in this commit:
1 - break verify_data in the server Finished message
2 - break signed_params hash in ServerKeyExchange
3 - break Signature in ServerKeyExchange

Correctly behaving TLS client must abort connection if any of these
failures is detected and as such, shall not transmit continue the
session.

commands to be sent. In addition, a control interface command is added
to expose this new interface outside wpa_supplicant:

Vendor command's format:
VENDOR <vendor id> <sub command id> [<hex formatted data>]

The 3rd argument will be converted to binary data and then passed as
argument to the sub command.

This interface is driver independent, but for now, this is only
implemented for the nl80211 driver interface using the cfg80211 vendor
commands.

Felix Fietkau d0595b25b4 nl80211: Fix tearing down WDS STA interfaces
wpa_driver_nl80211_if_remove() checks bss->if_added before deleting an
interface, which is 0 for the first BSS. The only part of
wpa_driver_nl80211_if_remove() that should get called for WDS STA
interfaces is the call to nl80211_remove_iface(), which can be pulled in
here directly.

It looks like some deployed devices may send an invalid supported

due to an invalid argument (cfg80211 mandates supported operating
classes information to have a length of 2..253 octets).

Work around this interop issue by ignoring the Supported Operating Class
