Add new control interface commands "DPP_NFC_HANDOVER_REQ own=<id>
uri=<URI>" and "DPP_NFC_HANDOVER_SEL own=<id> uri=<URI>" to support NFC
negotiated connection handover. These commands are used to report a DPP
URI received from a peer NFC Device in Handover Request and Handover

or FAIL on failure. The returned ID is used similarly to any other
bootstrapping information to initiate DPP authentication.

Initial OWE implementation used SHA256 when deriving the PTK for all OWE
groups. This was supposed to change to SHA384 for group 20 and SHA512
for group 21. The new owe_ptk_workaround parameter can be used to enable
workaround for interoperability with stations that use SHA256 with
groups 20 and 21. By default, only the appropriate hash function is
accepted. When workaround is enabled (owe_ptk_workaround=1), the
appropriate hash function is tried first and if that fails, SHA256-based
PTK derivation is attempted. This workaround can result in reduced
security for groups 20 and 21, but is required for interoperability with
older implementations. There is no impact to group 19 behavior.

Add the new set_key() parameter "key_flag" to provide more specific
description of what type of a key is being configured. This is needed to
be able to add support for "Extended Key ID for Individually Addressed
Frames" from IEEE Std 802.11-2016. In addition, this may be used to
replace the set_tx boolean eventually once all the driver wrappers have
moved to using the new key_flag.
The following flag are defined:
KEY_FLAG_MODIFY
Set when an already installed key must be updated.
So far the only use-case is changing RX/TX status of installed
keys. Must not be set when deleting a key.
KEY_FLAG_DEFAULT
Set when the key is also a default key. Must not be set when
deleting a key. (This is the replacement for set_tx.)
KEY_FLAG_RX
The key is valid for RX. Must not be set when deleting a key.
KEY_FLAG_TX
The key is valid for TX. Must not be set when deleting a key.
KEY_FLAG_GROUP
The key is a broadcast or group key.
KEY_FLAG_PAIRWISE
The key is a pairwise key.
KEY_FLAG_PMK
The key is a Pairwise Master Key (PMK).
Predefined and needed flag combinations so far are:
KEY_FLAG_GROUP_RX_TX
WEP key not used as default key (yet).
KEY_FLAG_GROUP_RX_TX_DEFAULT
Default WEP or WPA-NONE key.
KEY_FLAG_GROUP_RX
GTK key valid for RX only.
KEY_FLAG_GROUP_TX_DEFAULT
GTK key valid for TX only, immediately taking over TX.
KEY_FLAG_PAIRWISE_RX_TX
Pairwise key immediately becoming the active pairwise key.
KEY_FLAG_PAIRWISE_RX
Pairwise key not yet valid for TX. (Only usable with Extended Key ID
support.)
KEY_FLAG_PAIRWISE_RX_TX_MODIFY
Enable TX for a pairwise key installed with KEY_FLAG_PAIRWISE_RX.
KEY_FLAG_RX_TX
Not a valid standalone key type and can only used in combination
with other flags to mark a key for RX/TX.
This commit is not changing any functionality. It just adds the new
key_flag to all hostapd/wpa_supplicant set_key() functions without using
it, yet.

This extends hostapd and wpa_supplicant DPP implementation to allow the
bootstrapping URI to be generated for and parsed from an NFC Tag with an
NFC URI Record. This is similar to the way the bootstrapping URI is used
with QR Code for unidirectional authentication.
The DPP_BOOTSTRAP_GEN command uses "type=nfc-uri" to request the URI to
be assigned for NFC URI Record. In practice, the URI is generated
identically to the QR Code case, but the internal entry maintains the
NFC-URI type.
A new command "DPP_NFC_URI <uri>" can now be used to parse the URI read
from an NFC Tag with the NFC URI Record. This is similar to the
DPP_QR_CODE command.
Other commands (mainly, DPP_LISTEN and DPP_AUTH_INIT) are used for NFC

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.

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.

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.

This patch adds a new flag 'crl_reload_interval' to reload CRL
periodically. This can be used to reload ca_cert file and the included
CRL information on every new TLS session if difference between the last
reload and the current time in seconds is greater than
crl_reload_interval.
This reloading is used for cases where check_crl is 1 or 2 and the CRL
is included in the ca_file.

The wpa_psk_file can now be modified and hostapd can be told to re-read
it with the control interface RELOAD_WPA_PSK command:
$ hostapd_cli reload_wpa_psk
It must be noted special care must be taken if WPS is configured
(wps_state=2, eap_server=1) because WPS appends PMKs to the
wpa_psk_file.

It is now possible to optionally specify keyid for
each wpa_psk_file entry:
keyid=something 00:00:00:00:00:00 secretpassphrase
When station connects and the passphrase it used
has an associated keyid it will be appended to the
AP-STA-CONNECTED event string:
wlan0: AP-STA-CONNECTED 00:36:76:21:dc:7b keyid=something
It's also possible to retrieve it through the control interface:
$ hostapd_cli all_sta
Selected interface 'ap0'
00:36:76:21:dc:7b
...
keyid=something
New hostapd is able to read old wpa_psk_file. However, old hostapd will
not be able to read the new wpa_psk_file if it includes keyids.

There is currently no support for setting hostapd_bss_config.pbss from a
config file, i.e., it was used only based on automatic logic in
wpa_supplicant. This patch adds a key naturally called "pbss" which can
be used to set it.

There is no need to allow symlink dereferencing in these cases where a
file (including directories and sockets) are created by the same
process, so use the safer lchown() variant to avoid leaving potential
windows for something external to replace the file before the chown()
call. The particular locations used here should not have write
permissions enabled for processes with less privileges, so this may not
be needed, but anyway, it is better to make these more restrictive
should there be cases where directory permissions are not as expected
for a good deployment.

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]

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.

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.

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.
