dd5d325b0a hostapd: Add configuration option check_crl_strict
Add the ability to ignore time-based CRL errors from OpenSSL by
specifying a new configuration parameter, check_crl_strict=0.

This causes the following:

- This setting does nothing when CRL checking is not enabled.

- When CRL is enabled, "strict mode" will cause CRL time errors to not
  be ignored and will continue behaving as it currently does.

- When CRL is enabled, disabling strict mode will cause CRL time
  errors to be ignored and will allow connections.

By default, check_crl_strict is set to 1, or strict mode, to keep
current functionality.

b98933eafc HS 2.0: DHCP broadcast-to-unicast conversion before address learning
handle_dhcp() was first trying to learn the IP address of an associated
STA before doing broadcast-to-unicast conversion. This could result in
not converting some DHCPACK messages since the address learning part
aborts processing by returning from the function in various cases.

Reorder these operations to allow broadcast-to-unicast conversion to
happen even if an associated STA entry is not updated based on a
DHCPACK.

23693c9dac mka: Make ICV Indicator dependant on ICV length
IEEE Std 802.1X-2010, 11.11 describes that the ICV is separate from the
parameter sets before it. Due to its convenient layout the ICV Indicator
'body part' is used to encode the ICV as well.

IEEE Std 802.1X-2010, 11.11.3 describes the encoding of MKPDUs. In
bullet e) is desribed that the ICV Indicator itself is encoded when the
ICV is not 16 octets in length. IEEE Std 802.1Xbx-2014, Table 11-7 note
e) states that it will not be encoded unless the Algorithm Agility
parameter specifies the use of an ICV that is not 16 octets in length.

Therefore the length calculation for the ICV indicator body part must
take into account if the ICV Indicator is to be encoded or not. The
actual encoder of the ICV body already takes care of the rest.

In practice, this change will remove the ICV Indicator parameter set (4
octets before the ICV value itself) since the only defined algorithm
agility value uses an ICV of 16 octets. IEEE Std 802.1X-2010 MKPDU
validation and decoding rules in 11.11.2 and 11.11.4 require the
receipient to handle both cases of ICV Indicator being included or not.

626bc1fac2 mka: Stop trying to generate and distribute new SAK when not key server
It was possible for a participant to first be elected as a key server
and schedule a new SAK to be generated and distributed just to be
followed by another participant being elected as the key server. That

not correct behavior, so make these steps conditional on the participant
still being a key server when going through the timer.

This pointer needs to be cleared when the matching SAK is being removed
from the SAK list. The previous implementation was doing something
pretty strange in the loop by clearing the pointer for any non-matching
key that happened to be iterated through before finding the matching
key. This could probably result in incorrect behavior, but not clearing
the pointer for the matching key could do more harm by causing freed

302bbad5ac mka: Do not update potential peer liveness timer
To prevent a remote peer from getting stuck in a perpetual 'potential
peer' state, only update the peer liveness timer 'peer->expire' for live
peers and not for potential peers.

Per IEEE Std 802.1X-2010, 9.4.3 (Determining liveness), potential peers
need to show liveness by including our MI/MN in their transmitted MKPDU
(within potential or live parameter sets).

When a potential peer does include our MI/MN in an MKPDU, we respond by
moving the peer from 'potential_peers' to 'live_peers'.

If a potential peer does not include our MI/MN in an MKPDU within
MKPDU_LIFE_TIME, let the peer expire to facilitate getting back in sync
with the remote peer.

db9ca18bbf mka: Do not ignore MKPDU parameter set decoding failures
The status values returned by mka_param_body_handler.body_rx functions
are currently ignored by ieee802_1x_kay_decode_mkpdu(). If a failure is
detected the KaY should (a) stop processing the MKDPU and (b) do not
update the associated peer's liveliness.

IEEE Std 802.1X-2010, Table 11-7 (MKPDU parameter sets) and 11.11.3
(Encoding MKPDUs) dictate that MKA_SAK_USE (set type 3) will always be
encoded before MKA_DISTRIBUTED_SAK (set type 4) in MKPDUs. Due to
implementation of mka_param_body_handler, the code will always decode
MKA_SAK_USE before MKA_DISTRIBUTED_SAK. When MKA_DISTRUBUTED_SAK
contains a new SAK the code should decode MKA_DISTRUBUTED_SAK first so
that the latest SAK is in known before decoding MKA_SAK_USE.

The ideal solution would be to make two passes at MKDPU decoding: the
first pass decodes MKA_DISTRIBUTED_SAK, the second pass decodes all
other parameter sets.

A simpler and less risky solution is presented here: ignore MKA_SAK_USE
failures if MKA_DISTRIBUTED_SAK is also present. The new SAK will be
saved so that the next MKPDU's MKA_SAK_USE can be properly decoded. This
is basically what the code prior to this commit was doing (by ignoring
all errors).

Also, the only real recourse the KaY has when detecting any bad
parameter set is to ignore the MKPDU by not updating the corresponding
peer's liveliness timer, 'peer->expire'.

bab1d0d359 mka: Fix resource leak when detecting duplicated SCI
If a live peer ever changes its Member Identifier (MI), the KaY
correctly detects a "duplicated SCI" but then proceeds to delete the
peer without deleting the peer's resources (i.e., RxSC, RxSAs, TxSAs).

Note that a remote peer's MI will change if and when an
ieee8021XPaePortInitialize is executed on the remote port.

The solution here is to ignore all MKPDUs containing the new MI until
after the peer (that corresponds to the old MI) expires and cleans up
its resources. After the old peer is removed reception of the next MKPDU
containing the new MI will result in the creation of a new peer with the
new MI.

2fc0675683 mka: Fix lowest acceptable Packet Number (LPN) calculation and use
The purpose of the Lowest Acceptable PN (lpn) parameters in the MACsec
SAK Use parameter set is to enforce delay protection. Per IEEE Std
802.1X-2010, Clause 9, "Each SecY uses MKA to communicate the lowest PN
used for transmission with the SAK within the last two seconds, allowing
receivers to bound transmission delays."

When encoding the SAK Use parameter set the KaY should set llpn and olpn
to the lowest PN transmitted by the latest SAK and oldest SAK (if
active) within the last two seconds. Because MKPDUs are transmitted
every 2 seconds (MKA_HELLO_TIME), the solution implemented here
calculates lpn based on the txsc->next_pn read during the previous MKPDU
transmit.

Upon receiving and decoding a SAK Use parameter set with delay
protection enabled, the KaY will update the SecY's lpn if the delay
protect lpn is greater than the SecY's current lpn (which is a product
of last PN received and replay protection and window size).

d9a0a72229 mka: Fix MKPDU SAK Use Body's Delay Protect bit setting
Delay Protect and Replay Protect are two separate and distinct features
of MKA. Per IEEE Std 802.1X-2010, 9.10.1 "Delay Protect, TRUE if LPNs
are being reported sufficiently frequently to allow the recipient to
provide data delay protection. If FALSE, the LPN can be reported as
zero", and per 9.10 "NOTE--Enforcement of bounded received delay
necessitates transmission of MKPDUs at frequent (0.5 s) intervals, to
meet a maximum data delay of 2 s while minimizing connectivity
interruption due to the possibility of lost or delayed MKPDUs."

This means struct ieee802_1x_mka_sak_use_body::delay_protect should only
be set TRUE when MKPDUs are being transmitted every 0.5 s (or faster).
By default the KaY sends MKPDUs every MKA_HELLO_TIME (2.0 s), so by
default delay_protect should be FALSE.

Add a new 'u32 mka_hello_time' parameter to struct ieee802_1x_kay. If
delay protection is desired, the KaY initialization code should set
kay->mka_hello_time to MKA_BOUNDED_HELLO_TIME (500 ms).

dbe7f6da77 Vendor command to query the supported AKMs from the driver
This new QCA vendor command is used to query the supported AKM suite
selectors from the driver. There has been no such capability indication
from the driver and thus the current user space has to assume the driver
to support all the AKMs. This may be the case with some drivers (e.g.,
mac80211-based ones) but there are cfg80211-based drivers that implement
SME and have constraints on which AKMs can be supported (e.g., such
drivers may need an update to support SAE AKM using
NL80211_CMD_EXTERNAL_AUTH). Allow such drivers to specify the exact set
of supported AKMs so that user space tools can determine what network
profile options should be allowed to be configured. This command returns
the list of supported AKM suite selectors in the attribute
NL80211_ATTR_AKM_SUITES.

ASN1_STRING_get0_data is present in recent OpenSSL, but absent in some
versions of LibreSSL (confirmed for version 2.6.5), so fallback needs to
be defined in this case, just like for old OpenSSL.

This patch was inspired by similar patches to other projects, such as

and process Multi-AP IE from (Re)Association Response frames if the user
enables Multi-AP fuctionality. If the (Re)Association Response frame
does not contain the Multi-AP IE, disassociate.

This adds a new configuration parameter 'multi_ap_backhaul_sta' to
enable/disable Multi-AP functionality.

Enable 4-address mode after association (if the Association Response
frame contains the Multi-AP IE). Also enable the bridge in that case.
This is necessary because wpa_supplicant only enables the bridge in

9c06f0f6ae hostapd: Add Multi-AP protocol support
The purpose of Multi-AP specification is to enable inter-operability
across Wi-Fi access points (APs) from different vendors.

This patch introduces one new configuration parameter 'multi_ap' to
enable Multi-AP functionality and to configure the BSS as a backhaul
and/or fronthaul BSS.

Advertise vendor specific Multi-AP capabilities in (Re)Association
Response frame, if Multi-AP functionality is enabled through the
configuration parameter.

A backhaul AP must support receiving both 3addr and 4addr frames from a
backhaul STA, so create a VLAN for it just like is done for WDS, i.e.,
by calling hostapd_set_wds_sta(). Since Multi-AP requires WPA2 (never
WEP), we can safely call hostapd_set_wds_encryption() as well and we can
reuse the entire WDS condition.

To parse the Multi-AP Extension subelement, we use get_ie(): even though
that function is meant for parsing IEs, it works for subelements.

f9da7505bf OCV: Include and verify OCI in SA Query frames
Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.

On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.

Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.

As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.

17adac9ef9 FILS: Do not process FILS HLP request again while previous one is pending
It is better not to process a new (most likely repeated) FILS HLP
request if a station retransmits (Re)Association Request frame before
the previous HLP response has either been received or timed out. The
previous implementation ended up doing this and also ended up
rescheduling the fils_hlp_timeout timer in a manner that prevented the
initial timeout from being reached if the STA continued retransmitting
the frame. This could result in failed association due to a timeout on
the station side.

Make this more robust by processing (and relaying to the server) the HLP
request once and then ignoring any new HLP request while the response
for the relayed request is still pending. The new (Re)Association
Request frames are otherwise processed, but they do not result in actual
state change on the AP side before the HLP process from the first
pending request is completed.

This fixes hwsim test case fils_sk_hlp_oom failures with unmodified
mac80211 implementation (i.e., with a relatively short retransmission
timeout for (Re)Association Request frame).

bd51246924 nl80211: Debug print TX queue parameter values and result
Some mac80211_hwsim test cases have failed with mysterious sequence
where mac80211 has claimed the parameters are invalid ("wlan3: invalid
CW_min/CW_max: 9484/40"). Those values look strange since they are not
from hostapd configuration or default values.. hostapd is seeing TX
queue parameter set failing for queues 0, 1, and 3 (but not 2) for these
cases. Add debug prints to hostapd to get more details on what exactly
is happening if such error cases can be reproduced.

e0785ebbbd Use more consistent Action frame RX handling in both AP mode paths
Both handle_action() and hostapd_action_rx() are used for processing
received Action frames depending on what type of driver architecture is
used (MLME in hostapd vs. driver) and which build options were used to
build hostapd. These functions had a bit different sequence for checking
the frame and printing debug prints. Make those more consistent by
checking that the frame includes the category-specific action field and
some payload. Add a debug print for both functions to make it easier to
see which path various Action frames use.

a626fb1070 Add QCA vendor event to indicate throughput changes
Add interface for drivers to report changes in TX/RX throughput
dynamically to user space. This information can be used by userspace
tools to tune kernel's TCP parameters in order to achieve peak
throughput. The driver may optionally provide guidance on which TCP
parameters to be configured for optimal performance along with the
values to be configured.

The TCP parameters that need to be tuned for peak performance are not
interface specific. Based on the guidance from the driver and
considering the other interfaces that may be affected with the new
configurations, a userspace tool has to choose the values to be
configured for these parameters to achieve optimal performance across
interfaces.

The throughput levels informed by the driver with this event are only
for providing guidance on TCP parameter tuning from userspace. The
driver may change the thresholds used to decide low or medium or high
throughput levels based on several parameters based on the PHY layer
capacity in the current connection, the number of packets being
dispatched per second, or the number of packets pending in queues, etc.
The throughput levels may not be consistent with the actual throughput
of the link.

d514b50265 WNM: Collocated Interference Reporting
Add support for negotiating WNM Collocated Interference Reporting. This
allows hostapd to request associated STAs to report their collocated
interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.

For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".

For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".

This commit adds support for reporting changes in the collocated
interference (Automatic Report Enabled == 1 and partial 3), but not for
periodic reports (2 and other part of 3).

1737eb3982 Create debug log file with more sane file permissions
Previously the file permissions for the debug log file were not
explicitly set. Instead it was implicitly relying on a secure umask,
which in most cases would result in a file that is world-readable. This
is a violation of good practices, since not every user should have
access to sensitive information that might be contained in the debug log
file.

Explicitly set sane default file permissions in case the file is newly
created.

Unfortunately the fopen(3) function does not provide such a facility, so
the approach needs to be changed in the following way:

1) The file descriptor needs to be created manually using the open(3)
function with the correct flags and the desired mode set.

2) fdopen(3) can then be used on the file descriptor to associate a file
stream with it.

Note: This modification will not change the file permissions of any
already existing debug log files, and only applies to newly created
ones.

edb28006c4 PMF: Do not start SA Query procedure if there is no association
Previous implementation ended up triggering PMF check for previous
association and SA Query procedure incorrectly in cases where there is a
STA entry in hostapd, but that STA is not in associated state. This
resulted in undesired temporary rejection of the association with status
code 30.

This ended up breaking OWE group negotiation when PMF is in use since
the check for the OWE group would have happened only after this earlier
PMF check and rejection (i.e., the station got status code 30 instead of
the expected 77).

For example, when the AP is configured with OWE group 21 and a station
tries groups 19, 20, and 21 (in this sequence), the first two
Association Request frames should be rejected with status code 77.
However, only the first one got that status code while the second one
got status code 30 due to that issue with PMF existing association
check.

Furthermore, hostapd was continuing with SA Query procedure with
unencrypted Action frames in this type of case even though there was no
existing association (and obviously, not an encryption key either).

Fix this by checking that the STA entry is in associated state before
initiating SA Query procedure based on the PMF rules.

17d4b77472 RSN: Do not replace existing Suite B PMKSA on 4-way handshake
PMKID derivation with the Suite B AKMs is a special case compared to
other AKMs since that derivation uses KCK instead of PMK as an input.
This means that the PMKSA cache entry can be added only after KCK has
been derived during 4-way handshake. This also means that PMKID would
change every time 4-way handshake is repeated even when maintaining the
same PMK (i.e., during PTK rekeying and new associations even if they
use PMKSA caching).

wpa_supplicant was previously replacing the PMKSA cache entry whenever a
new PMKID was derived. This did not match hostapd expectations on the AP
side since hostapd did not update the PMKSA cache entry after it was
created. Consequently, PMKSA caching could be used only once (assuming
no PTK rekeying happened before that). Fix this by making wpa_supplicant
behave consistently with hostapd, i.e., by adding the Suite B PMKSA
cache entries with the PMKID from the very first 4-way handshake
following PMK derivation and then not updating the PMKID.

IEEE Std 802.11-2016 is somewhat vague in this area and it seems to
allow both cases to be used (initial PMKID or any consecutive PMKID
derived from the same PMK). While both cases could be supported that
would result in significantly more complex implementation and need to
store multiple PMKID values. It looks better to clarify the standard to
explicitly note that only the first PMKID derived after PMK derivation
is used (i.e., match the existing hostapd implementation).

Commit 3f53c006c7 ('nl80211: Ignore
disconnect event in case of locally generated request') made
wpa_supplicant ignore the next received disconnect event for cases where
wpa_supplicant itself requested a disconnection. This can result in
ignoring a disconnection notification in some cases.

Considering a P2P Client receiving disconnect event from the kernel
after a P2P group is started, drv->ignore_next_local_disconnect is
cleared to 0, then wpa_driver_nl80211_disconnect() will be called during
the removal of the group, in which drv->ignore_next_local_disconnect is
set to 1 by mistake.

Do not allow ignore_next_local_{disconnect,deauth} to be set to 1 if the
driver is not in associated state (drv->associated is 0) to avoid this
type of cases.

When using WPA2, EAPOL-Key frames that had the Encrypted flag set but

the MIC. In case the data field was encrypted using RC4 (i.e., when

unauthenticated but decrypted data would then be processed. An adversary
could abuse this as a decryption oracle to recover sensitive information

4a0e011560 AP: Fix HT 20/40 co-ex transition timer cancellation on iface removal
When removing an interface, hostapd_bss_deinit() frees all associated
STAs. If any of the stations is 40MHz intolerant, the cleanup invokes
ht40_intolerant_remove(), that in turn registers a 20->40MHz transition
timer for the last station (ap_ht2040_timeout() function). That timer is
never canceled; once it executes, the interface is gone, most likely
resulting in a segfault when referencing it.

While hostapd_interface_deinit() cancels the transition timer, it does
so before cleaning up STAs. Move the cancellation after STA cleanup to
cancel any timer that was registered during that operation.

c3e4f40cd6 FT: Derive PMKR0Name/PMKR1Name using SHA-384 with AKM 00-0F-AC:13
The AKM 00-0F-AC:13 is supposed to use cryptographic algorithms
consistently, but the current IEEE 802.11 standard is not doing so for
the key names: PMKID (uses SHA-1), PMKR0Name/PMKR1Name (uses SHA-256).
The PMKID case was already implemented with SHA-384 and this commit
replaces use of SHA-256 with SHA-384 for PMKR0Name/PMKR1Name derivation
to be consistent in SHA-384. While this is not compliant with the
current IEEE 802.11 standard, this is clearly needed to meet CNSA Suite
requirements. Matching change is being proposed in REVmd to get the IEEE
802.11 standard to meet the use case requirements.

e8d08cf378 SAE: Do not drop STA entry on reauthentication in infrastructure BSS
A new SAE Commit message should not be allowed to drop an existing STA
entry since the sender of that Commit message cannot be authenticated
before receiving the Confirm message. This is important in particular
when PMF is used since this would provide a potential new path for
forcing a connection to be dropped.

Fix this by allowing a new SAE Authentication instance to be started
when the old instance is in Accepted state and the new Commit message
does not use the same peer-scalar value (checked in
sae_parse_commit_scalar()). When PMF is used, the AP will use SA Query
procedure when receiving the (Re)Association Request frame. In theory,
that step could be skipped in case of SAE Authentication since the
non-AP STA is demonstrating knowledge of the password. Anyway, there is
no allowance for that exception in the IEEE 802.11 standard, so at least
for now, leave this using SA Query procedure just like any other PMF
case.

bda9c08596 hostapd: Fix CHAN_SWITCH command for VHT20 and VHT40
Previously, hostapd CHAN_SWITCH command did not effect VHT configuration
for the following:

When VHT is currently disabled (ieee80211ac=0),

1. hostapd_cli -p /var/run/hostapd chan_switch 10 5180 \
                sec_channel_offset=1 center_freq1=5190 bandwidth=40 ht

====> Comes up in HT40

2. hostapd_cli -p /var/run/hostapd chan_switch 10 5765 \
                sec_channel_offset=-1 center_freq1=5775 bandwidth=40 vht

====> Comes up in HT40

3. hostapd_cli -p /var/run/hostapd chan_switch 10 5200 center_freq1=5200 \
                                                  bandwidth=20 vht

====> Comes up in HT20

When VHT is currently enabled (ieee80211ac=1),

1. hostapd_cli -p /var/run/hostapd chan_switch 10 5180 \
                sec_channel_offset=1 center_freq1=5190 bandwidth=40 ht

====> Comes up in VHT40

2. hostapd_cli -p /var/run/hostapd chan_switch 10 5200 center_freq1=5200 \
                                                  bandwidth=20 ht

====> Comes up in VHT20

This is since VHT config from chan_switch is processed only for
bandwidths 80 and above (80P80, 160) and for VHT20, VHT40 cases, only
NLA chan type and chan width are updated.

There is no NL attribute for determining if it is HT or VHT for
bandwidths 20 & 40 and currently they are updated as HT20, HT40 (+ or -
depending on offset). Same is notified back via
NL80211_CMD_CH_SWITCH_NOTIFY.

Instead of adding new NL attribute for tracking HT/VHT enabled config,
we are adding new hostapd VHT config parameter to save the chan_switch
config and use only for chan_switch case of VHT20 and VHT40.

Tested with all combinations of chan_switch (noHT->20->40->80->) HT/VHT
and confirmed to be working.

c4dd3afa3c ACS: Avoid invalid interference factor when survey channel time is zero
When the channel time is zero the interference factor calculation falls
under divide by zero operation which results in invalid (NaN =
not-a-number) interference factor value. This leads to wrong ideal
channel selection in ACS during the scenario described below.

Scenario:

In VHT80 mode, the channel 36 (first channel) gets the channel time as
zero which causes the interfactor factor to be an invalid number (NaN).
Any operations (like addition, mulitplication, divide, etc.) with NaN
value results in a NaN value, so that average factor for the primary
channel 36 got the invalid value (NaN). Since channel 36 is the first
channel, ideal factor is assigned as NaN in the first iteration. The
following iteration condition check (factor < ideal_factor) with a NaN
value fail for all other primary channels. This results in channel 36
being chosen as the ideal channel in ACS which holds a NaN value.

Logs:

ACS: Survey analysis for channel 36 (5180 MHz)
ACS: 1: min_nf=-103 interference_factor=nan nf=0 time=0 busy=0 rx=0
ACS: 2: min_nf=-103 interference_factor=0.615385 nf=-102 time=13 busy=8 rx=0

by using separate buffers for the pathname and response buffer.

d501c27cfe EAP-TLS server: Disable TLS v1.3 by default
The current EAP peer implementation is not yet ready for the TLS v1.3
changes with EAP-TTLS, EAP-PEAP, and EAP-FAST, so disable TLS v1.3 for
this EAP method for now.

While the current EAP-TLS implementation is more or less complete for
TLS v1.3, there has been no interoperability testing with other
implementations, so disable for by default for now until there has been
chance to confirm that no significant interoperability issues show up
with TLS version update. tls_flags=[ENABLE-TLSv1.3] configuration
parameter can be used to enable TLS v1.3 (assuming the TLS library
supports it; e.g., when using OpenSSL 1.1.1).

OpenSSL 1.1.1 added cases where ClientHello generation may fail due to
"no ciphers available". There is no point in sending out the resulting
TLS Alert message to the server since the server does not know what to
do with it before ClientHello. Instead, simply terminate the TLS
handshake locally and report EAP failure to avoid getting stuck waiting
for a timeout.
