Jouni Malinen 76ddfae6eb EAP-TEAP server: Testing mechanism for Result TLV in a separate message
The new eap_teap_separate_result=1 hostapd configuration parameter can
be used to test TEAP exchange where the Intermediate-Result TLV and
Crypto-Binding TLV are send in one message exchange while the Result TLV
exchange in done after that in a separate message exchange.

Jouni Malinen e2722bf81d OpenSSL: Allow two server certificates/keys to be configured on server
hostapd EAP server can now be configured with two separate server
certificates/keys to enable parallel operations using both RSA and ECC
public keys. The server will pick which one to use based on the client
preferences for the cipher suite (in the TLS ClientHello message). It
should be noted that number of deployed EAP peer implementations do not
filter out the cipher suite list based on their local configuration and
as such, configuration of alternative types of certificates on the
server may result in interoperability issues.

Jouni Malinen 0ed57c5ea8 EAP-TEAP server and peer implementation (RFC 7170)
This adds support for a new EAP method: EAP-TEAP (Tunnel Extensible
Authentication Protocol). This should be considered experimental since
RFC 7170 has number of conflicting statements and missing details to
allow unambiguous interpretation. As such, there may be interoperability
issues with other implementations and this version should not be
deployed for production purposes until those unclear areas are resolved.

This does not yet support use of NewSessionTicket message to deliver a
new PAC (either in the server or peer implementation). In other words,
only the in-tunnel distribution of PAC-Opaque is supported for now. Use
of the NewSessionTicket mechanism would require TLS library support to
allow arbitrary data to be specified as the contents of the message.

Toke Høiland-Jørgensen ef7217518b hostapd: Add airtime policy configuration support
This adds support to hostapd for configuring airtime policy settings for
stations as they connect to the access point. This is the userspace
component of the airtime policy enforcement system PoliFi described in
this paper: https://arxiv.org/abs/1902.03439

The Linux kernel part has been merged into mac80211 for the 5.1 dev
cycle.

The configuration mechanism has three modes: Static, dynamic and limit.
In static mode, weights can be set in the configuration file for
individual MAC addresses, which will be applied when the configured
stations connect.

In dynamic mode, weights are instead set per BSS, which will be scaled
by the number of active stations on that BSS, achieving the desired
aggregate weighing between the configured BSSes. Limit mode works like
dynamic mode, except that any BSS *not* marked as 'limited' is allowed
to exceed its configured share if a per-station fairness share would
assign more airtime to that BSS. See the paper for details on these
modes.

Davina Lu 66819b07b5 hostapd: Support Multi-AP backhaul STA onboarding with WPS
The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the WPS Registrar offers a
different set of credentials (backhaul credentials instead of fronthaul
credentials) when the Multi-AP subelement is present in the WFA vendor
extension element of the WSC M1 message.

Add new configuration options to specify the backhaul credentials for
the hostapd internal registrar: multi_ap_backhaul_ssid,
multi_ap_backhaul_wpa_psk, multi_ap_backhaul_wpa_passphrase. These are
only relevant for a fronthaul SSID, i.e., where multi_ap is set to 2 or
3. When these options are set, pass the backhaul credentials instead of
the normal credentials when the Multi-AP subelement is present.

Ignore the Multi-AP subelement if the backhaul config options are not
set. Note that for an SSID which is fronthaul and backhaul at the same
time (i.e., multi_ap == 3), this results in the correct credentials
being sent anyway.

The security to be used for the backaul BSS is fixed to WPA2PSK. The
Multi-AP Specification only allows Open and WPA2PSK networks to be
configured. Although not stated explicitly, the backhaul link is
intended to be always encrypted, hence WPA2PSK.

To build the credentials, the credential-building code is essentially
copied and simplified. Indeed, the backhaul credentials are always
WPA2PSK and never use per-device PSK. All the options set for the
fronthaul BSS WPS are simply ignored.

Jouni Malinen fe468b0714 HE: Fix set_he_cap() parsing of config options for MU EDCA Params
When I replaced the POS() function with ffs() when applying relevant
parts from the original patch, this ended up breaking the frame
construction since the POS() function was supposed to count the bit
offset for the mask with 0 being the LSB instead of 1 returned by ffs().
Furthermore, ffs() is not available in all C libraries (e.g., not
directly exposed by strings.h on Android), so better not depend on that
or compiler builtins for this since there is no need for this to be as
fast as possible in configuration parsing.

Fix this with a simple function to determine the number of bits the
value needs to be shifted left to align with the mask.

Jouni Malinen cc9c4feccc OpenSSL: Allow systemwide policies to be overridden
Some distributions (e.g., Debian) have started introducting systemwide
OpenSSL policies to disable older protocol versions and ciphers
throughout all programs using OpenSSL. This can result in significant
number of interoperability issues with deployed EAP implementations.

Allow explicit wpa_supplicant (EAP peer) and hostapd (EAP server)
parameters to be used to request systemwide policies to be overridden if
older versions are needed to be able to interoperate with devices that
cannot be updated to support the newer protocol versions or keys. The
default behavior is not changed here, i.e., the systemwide policies will
be followed if no explicit override configuration is used. The overrides
should be used only if really needed since they can result in reduced
security.

In wpa_supplicant, tls_disable_tlsv1_?=0 value in the phase1 network
profile parameter can be used to explicitly enable TLS versions that are
disabled in the systemwide configuration. For example,
phase1="tls_disable_tlsv1_0=0 tls_disable_tlsv1_1=0" would request TLS
v1.0 and TLS v1.1 to be enabled even if the systemwide policy enforces
TLS v1.2 as the minimum version. Similarly, openssl_ciphers parameter
can be used to override systemwide policy, e.g., with
openssl_ciphers="DEFAULT@SECLEVEL=1" to drop from security level 2 to 1
in Debian to allow shorter keys to be used.

In hostapd, tls_flags parameter can be used to configure similar
options. E.g., tls_flags=[ENABLE-TLSv1.0][ENABLE-TLSv1.1]

Nils Nieuwejaar ba4f3224ae Allow remote RADIUS authentication with local VLAN management
The documentation in the hostapd.conf file says that the dynamic_vlan
variable is used to control whether VLAN assignments are accepted from a
RADIUS server. The implication seems to be that a static VLAN assignment
will come from the accept_mac_file if dynamic_vlan is set to 0, and a
dynamic assignment will come from the RADIUS server if dynamic_vlan is
set to 1. Instead, I'm seeing that the static settings from the
accept_mac_file are ignored if dynamic_vlan is set to 0, but used if
dynamic_vlan is set to 1. If dynamic_vlan is set to 1 and the RADIUS
server does not provide a VLAN, then the accept_mac_file assignment is
overridden and the STA is assigned to the default non-VLANed interface.

If my understanding of the expected behavior is correct, then I believe
the problem is in ap_sta_set_vlan(). That routine checks the
dynamic_vlan setting, but has no way of determining whether the incoming
vlan_desc is static (i.e., from accept_mac_file) or dynamic (i.e., from
a RADIUS server).

I've attached a patch that gets hostapd working as I believe it's meant
to, and updates the documentation to make the implicit behavior
explicit.

The functional changes are:

- hostapd_allowed_address() will always extract the vlan_id from the
  accept_macs file. It will not update the vlan_id from the RADIUS cache
  if dynamic_vlan is DISABLED.

- hostapd_acl_recv_radius() will not update the cached vlan_id if
  dynamic_vlan is DISABLED.

- ieee802_1x_receive_auth() will not update the vlan_id if dynamic_vlan
  is DISABLED.

More cosmetic:

Most of the delta is just moving code out of ieee802_1x_receive_auth()
into a new ieee802_1x_update_vlan() routine. While I initially did this
because the new DISABLED check introduced excessive indentation, it has
the added advantage of eliminating the vlan_description allocation and
os_memset() call for all DYNAMIC_VLAN_DISABLED configs.

I've done a couple rounds of review offline with Michael Braun (who has
done much of the work in this part of the code) and incorporated his
feedback.

If dynamic_vlan=0 (disabled), vlan assignments will be managed using the
local accept_mac_file ACL file, even if a RADIUS server is being used
for user authentication. This allows us to manage users and devices
independently.

Lubomir Rintel 89a7cdd690 crypto: Add option to use getrandom()
According to random(4) manual, /dev/random is essentially deprecated on
Linux for quite some time:

"The /dev/random interface is considered a legacy interface, and
/dev/urandom is preferred and sufficient in all use cases, with the
exception of applications which require randomness during early boot
time; for these applications, getrandom(2) must be used instead, because
it will block until the entropy pool is initialized."

An attempt to use it would cause unnecessary blocking on machines
without a good hwrng even when it shouldn't be needed. Since Linux 3.17,
a getrandom(2) call is available that will block only until the
randomness pool has been seeded.

It is probably not a good default yet as it requires a fairly recent
kernel and glibc (3.17 and 2.25 respectively).

An AP might reject a STA association request due to low RSSI. In such
case, the AP informs the STA the desired RSSI improvement and a retry
timeout. The STA might retry to associate even if the RSSI hasn't
improved if the retry timeout expired.

Sam Voss 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.

Venkateswara Naralasetty 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.

Jouni Malinen 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).

Sathishkumar Muruganandam 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.

Michael Braun 3a3e28320b FT: Add expiration to PMK-R0 and PMK-R1 cache
IEEE Std 802.11-2016, 12.7.1.7.1 indicates that the lifetime of the
PMK-R0 (and PMK-R1) is bound to the lifetime of PSK or MSK from which
the key was derived. This is currently stored in r0_key_lifetime, but
cache entries are not actually removed.

This commit uses the r0_key_lifetime configuration parameter when
wpa_auth_derive_ptk_ft() is called. This may need to be extended to use
the MSK lifetime, if provided by an external authentication server, with
some future changes. For PSK, there is no such lifetime, but it also
matters less as FT-PSK can be achieved without inter-AP communication.

The expiration timeout is then passed from R0KH to R1KH. The R1KH verifies
that the given timeout for sanity, it may not exceed the locally configured
r1_max_key_lifetime.

The new hostapd.conf parameter sae_require_pmf=<0/1> can now be used to

Jouni Malinen 348c93847a AP-side workaround for WNM-Sleep Mode GTK/IGTK reinstallation issues
Normally, WNM-Sleep Mode exit with management frame protection
negotiated would result in the current GTK/IGTK getting added into the
WNM-Sleep Mode Response frame. Some station implementations may have a
vulnerability that results in GTK/IGTK reinstallation based on this
frame being replayed. Add a new hostapd configuration parameter that can
be used to disable that behavior and use EAPOL-Key frames for GTK/IGTK
update instead. This would likely be only used with

issues with EAPOL-Key. This is related to station side vulnerabilities

Jouni Malinen 3d6953288b Extend RESEND_* test commands to allow forcing plaintext TX
This allows hostapd testing functionality to be forced to send out a
plaintext EAPOL-Key frame with the RESEND_* command. That can be useful
in seeing how the station behaves if an unencrypted EAPOL frame is
received when TK is already configured.

This is not really perfect since there is no convenient way of sending
out a single unencrypted frame in the current nl80211 design. The
monitor interface could likely still do this, but that's not really
supposed to be used anymore. For now, clear and restore TK during this
operation. The restore part is not really working correctly, though,
since it ends up clearing the TSC value on the AP side and that shows up
as replay protection issues on the station. Anyway, this is sufficient
to generate sniffer captures to analyze station behavior.

Jouni Malinen 6f234c1e2e Optional AP side workaround for key reinstallation attacks
This adds a new hostapd configuration parameter
wpa_disable_eapol_key_retries=1 that can be used to disable
retransmission of EAPOL-Key frames that are used to install
keys (EAPOL-Key message 3/4 and group message 1/2). This is
similar to setting wpa_group_update_count=1 and
wpa_pairwise_update_count=1, but with no impact to message 1/4
retries and with extended timeout for messages 4/4 and group
message 2/2 to avoid causing issues with stations that may use
aggressive power saving have very long time in replying to the
EAPOL-Key messages.

This option can be used to work around key reinstallation attacks
on the station (supplicant) side in cases those station devices
cannot be updated for some reason. By removing the
retransmissions the attacker cannot cause key reinstallation with
a delayed frame transmission. This is related to the station side
vulnerabilities CVE-2017-13077, CVE-2017-13078, CVE-2017-13079,
CVE-2017-13080, and CVE-2017-13081.

This workaround might cause interoperability issues and reduced
robustness of key negotiation especially in environments with
heavy traffic load due to the number of attempts to perform the
key exchange is reduced significantly. As such, this workaround
is disabled by default (unless overridden in build
configuration). To enable this, set the parameter to 1.

It is also possible to enable this in the build by default by
adding the following to the build configuration:

CFLAGS += -DDEFAULT_WPA_DISABLE_EAPOL_KEY_RETRIES=1

Jouni Malinen a0bf1b68c0 Remove all PeerKey functionality
This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.

This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.

Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

Jouni Malinen ae048257cb WPS: Interpret zero length ap_pin hostapd.conf parameter as "unset"
hostapd allows arbitrary AP PIN to be used in WPS. This means that
setting ap_pin to a zero length string ends up enabling AP PIN so that
external registrars can use this specific zero lenth ap_pin value. There
are apparently some APs that have used this invalid configuration with
unintended results. While the proper fix for that is to fix the
component that generates the invalid configuration, hostapd can also
reject such values since the likelihood of a real world use case for
zero length AP PIN (Device Password) is minimal.

Start interpreting zero length ap_pin parameter value as a request to
"unset" the previously set value in hostapd.conf (or if not previously
set, leave it unset). With this, a hostapd.conf file including the
"ap_pin=" line will end up getting interpretted just like that same file
with the ap_pin parameter completely removed, i.e., with AP PIN being
disabled.

Michael Braun 3a46cf93d0 FT: Add support for wildcard R0KH/R1KH
Enable use of FT RRB without configuring each other AP locally. Instead,
broadcast messages are exchanged to discover APs within the local
network.

When an R0KH or R1KH is discovered, it is cached for one day.

When a station uses an invalid or offline r0kh_id, requests are always
broadcast. In order to avoid this, if r0kh does not reply, a temporary
blacklist entry is added to r0kh_list.

To avoid blocking a valid r0kh when a non-existing pmk_r0_name is
requested, r0kh is required to always reply using a NAK. Resend requests
a few times to ensure blacklisting does not happen due to small packet
loss.

To free newly created stations later, the r*kh_list start pointer in
conf needs to be updateable from wpa_auth_ft.c, where only wconf is
accessed.

Johannes Berg a1f11e34c4 Use os_memdup()
This leads to cleaner code overall, and also reduces the size
of the hostapd and wpa_supplicant binaries (in hwsim test build
on x86_64) by about 2.5 and 3.5KiB respectively.

The mechanical conversions all over the code were done with
the following spatch:

    @@
    expression SIZE, SRC;
    expression a;
    @@
    -a = os_malloc(SIZE);
    +a = os_memdup(SRC, SIZE);

Jouni Malinen ff936bc753 Make the third octet of Country String configurable
The new hostapd.conf parameter country3 can now be used to configure the
third octet of the Country String that was previously hardcoded to ' '
(= 0x20).

For example:

All environments of the current frequency band and country (default)
country3=0x20

Outdoor environment only
country3=0x4f

Indoor environment only
country3=0x49

Noncountry entity (country_code=XX)
country3=0x58

IEEE 802.11 standard Annex E table indication: 0x01 .. 0x1f
Annex E, Table E-4 (Global operating classes)
country3=0x04

CONFIG_TLS=linux can now be used to select the crypto implementation
that uses the user space socket interface (AF_ALG) for the Linux kernel
crypto implementation. This commit includes some of the cipher, hash,
and HMAC functions. The functions that are not available through AF_ALG
(e.g., the actual TLS implementation) use the internal implementation
(CONFIG_TLS=internal).

fixes some build configuration combinations where either of those

Günther Kelleter 41f140d386 Add hostapd options wpa_group_update_count and wpa_pairwise_update_count
wpa_group_update_count and wpa_pairwise_update_count can now be used to
set the GTK and PTK rekey retry limits (dot11RSNAConfigGroupUpdateCount
and dot11RSNAConfigPairwiseUpdateCount). Defaults set to current
hardcoded value (4).

Some stations may suffer from frequent deauthentications due to GTK
rekey failures: EAPOL 1/2 frame is not answered during the total timeout
period of currently ~3.5 seconds. For example, a Galaxy S6 with Android
6.0.1 appears to go into power save mode for up to 5 seconds. Increasing
wpa_group_update_count to 6 fixed this issue.

The new dhcp_server configuration parameter can now be used to configure
hostapd to act as a DHCP relay for DHCPDISCOVER messages received as
FILS HLP requests. The dhcp_rapid_commit_proxy=1 parameter can be used
to configure hostapd to convert 4 message DHCP exchange into a 2 message
exchange in case the DHCP server does not support DHCP rapid commit
option.

The fils_hlp_wait_time parameter can be used to set the time hostapd
waits for an HLP response. This matches the dot11HLPWaitTime in IEEE Std
