076f1ea1d9 OCE: Add RSSI based association rejection support (AP)
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.

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.

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.

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).

47abe29aa9 hostapd: SET ht_capab support for disabling 40 MHz bandwidth
'hostapd_cli SET ht_capab' only checked for [HT40+] or [HT40-] or both
to be present. Based on the offset + or -, secondary_channel is updated
but HT20/VHT20 mode can be brought up only from config file and can't be
done using the SET command when the current HT mode is HT40+ or HT40-.

When managing AP+STA mode from userspace doing hostapd_cli: "disable ->
set channel, ht_capab -> enable" sequence, channel switch from
HT40/VHT40 to HT20/VHT20 was not possible with this SET ht_capab
limitation.

Cover this additional case by resetting secondary_channel to 0 for
HT20/VHT20 when ht_capab has neither [HT40+] nor [HT40-] present.

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.

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.

0fa669bcae Fix a resource leak on hostapd maclist parsing error path
The open file needs to be closed in error case. The conversion to using
a new helper function (hostapd_add_acl_maclist) somehow managed to
remove the neede fclose(f) call. Bring it back to fix this.
