c60717f839 hostapd: Add support for DFS channels in CHAN_SWITCH
Enable support for DFS channels in the CHAN_SWITCH command. Perform CAC
instead of CSA if DFS channel is selected. Then restart normal AP
operations.

Note that the current implementation provides a simplified approach. It
does not check if the selected DFS channel block is already in the
HOSTAPD_CHAN_DFS_AVAILABLE state. CAC procedure is restarted anyway.

862aac1fcd AP: Support Extended Key ID
Support Extended Key ID in hostapd according to IEEE Std 802.11-2016.

Extended Key ID allows to rekey pairwise keys without the otherwise
unavoidable MPDU losses on a busy link. The standard is fully backward
compatible, allowing an AP to serve STAs with and without Extended Key
ID support in the same BSS.

4b04223f24 hostapd: Replace UDP ctrl_iface global cookies with per-instance ones
The cookie values for UDP control interface commands was defined as a
static global array. This did not allow multi-BSS test cases to be
executed with UDP control interface. For example, after
    hapd1 = hostapd.add_bss(apdev[0], ifname1, 'bss-1.conf')
    hapd2 = hostapd.add_bss(apdev[0], ifname2, 'bss-2.conf')

hapd1->ping() did not work.

Move those cookie values to per-instance location in struct
hapd_interfaces and struct hostapd_data to fix this.

12fb9698ab Use IFNAME= prefix for global UDP control interface events
There does not seem to be a good reason for using the different IFACE=
prefix on the UDP control interface. This got added when the UDP
interface in wpa_supplicant was extended in commit f0e5d3b5c6
("wpa_supplicant: Share attach/detach/send UDP ctrl_iface functions")
and that was then extended to hostapd in commit e920805685 ("hostapd:
Extend global control interface notifications").

Replace the IFACE= prefix in UDP case with IFNAME= to be consistent with
the UNIX domain socket based control interface.

This fixes a problem when at least one test case fail (hapd_ctrl_sta)
when remote/udp used. This also fixes test_connectivity().

a919a26035 Introduce and add key_flag
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.

e780b4bf20 DPP: Bootstrapping via NFC URI Record
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
URI in the same way as they are used for QR Code.

3c13af5573 hostapd: Register wpa_msg callback even if only global ctrl_iface is used
Previously, wpa_msg_register_cb() was called only from successful
completion of per-interface control interface initialization. This would
leave the callback unregistered in case only the global control

02f52ab6f5 Use lchown() instead of chown() for self-created files
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.

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).

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.

started. This is not really expected behavior, so stop the
authentication exchange first with this command to avoid restarting
listen operation.

1fafdf1124 DPP: Add DPP_LISTEN and DPP_STOP_LISTEN to hostapd
This is an initial step in allowing non-operating channel operations
with DPP when hostapd is the Responder. For now, this is only used for
specifying role=configurator/enrollee and qr=mutual cases similarly to
the wpa_supplicant configuration for in Responder role. Request to use a
non-operating channel will be rejected.

60239f60a6 DPP: Protocol testing framework
Add a generic mechanism for configuring the DPP implementation to behave
in particular different (mostly incorrect) ways for protocol testing
purposes. The new dpp_test parameter can be set to a non-zero integer to
indicate a specific behavior. This is only available in
CONFIG_TESTING_OPTIONS=y builds.

This commit include cases for an extra attribute being added after the
Wrapped Data attribute and Initiator/Responder capabilities having an
unexpected zero capability.

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.
