IDLE state while the implementation called this LISTEN. Rename the state
in the implementation to match the one used in the standard to avoid
confusion. In addition, rename OPEN_{SENT,RCVD} to OPN_{SNT,RCVD} to
match the exact spelling of these states in the standard.

Previously all TX status events with wildcard BSSID were ignored. This

IEEE Std 802.11-2012, 10.19 (Public Action frame addressing) specifies
that the wildcard BSSID value is used in Public Action frames that are
transmitted to a STA that is not a member of the same BSS. hostapd used
to use the actual BSSID value for all such frames regardless of whether
the destination STA is a member of the BSS.
Fix this by using the wildcard BSSID in cases the destination STA is not
a member of the BSS. Leave group addressed case as-is (i.e., the actual
BSSID), since both values are accepted. No such frames are currently
used, though.
This version is still using the AP BSSID value in the Address 3 field
for GAS response frames when replying to a GAS request with AP BSSID
instead of Wildcard BSSID. This is left as a workaround to avoid
interoperability issues with deployed STA implementations that are still
using the non-compliant address and that might be unable to process the
standard compliant case.

This avoids internal access of structs and also removes the dependency

Most protocols extracting keys from TLS use RFC 5705 exporters which is
commonly implemented in TLS libraries. This is the mechanism used by
EAP-TLS. (EAP-TLS actually predates RFC 5705, but RFC 5705 was defined
to be compatible with it.)
EAP-FAST, however, uses a legacy mechanism. It reuses the TLS internal
key block derivation and derives key material after the key block. This
is uncommon and a misuse of TLS internals, so not all TLS libraries
support this. Instead, we reimplement the PRF for the OpenSSL backend
and don't support it at all in the GnuTLS one.
Since these two are very different operations, split
tls_connection_prf() in two. tls_connection_export_key() implements the
standard RFC 5705 mechanism that we expect most TLS libraries to
support. tls_connection_get_eap_fast_key() implements the
EAP-FAST-specific legacy mechanism which may not be implemented on all
backends but is only used by EAP-FAST.

BoringSSL added OpenSSL 1.1.0's SSL_get_client_random() and friends in

still looks more like 1.0.2 than 1.1.0 and advertises
OPENSSL_VERSION_NUMBER as such. This means that there is no need to
define those in BoringSSL and defining them causes conflicts. (C does
not like having static and non-static functions with the same name.)
As requested, this is conditioned on defined(BORINGSSL_API_VERSION) so
wpa_supplicant may continue to support older BoringSSLs for a time.
(BoringSSL revisions without the accessors predate BoringSSL maintaining
a BORINGSSL_API_VERSION.)

One of supported code paths already allows this scenario. It is used if
driver doesn't report NL80211_ATTR_DEVICE_AP_SME and doesn't support
monitor interface. In such situation:
1) We don't quit if subscribing for WLAN_FC_STYPE_PROBE_REQ fails
2) We don't try subscribing for WLAN_FC_STYPE_ACTION
3) We fallback to AP SME mode after failing to create monitor interface
4) We don't quit if subscribing for WLAN_FC_STYPE_PROBE_REQ fails
Above scenario is used, e.g., with brcmfmac. As you can see - thanks to
events provided by cfg80211 - it's not really required to receive Probe
Request or action frames.
However, the previous implementation did not allow using hostapd with
drivers that:
1) Report NL80211_ATTR_DEVICE_AP_SME
2) Don't support subscribing for PROBE_REQ and/or ACTION frames
In case of using such a driver hostapd will cancel setup after failing
to subscribe for WLAN_FC_STYPE_ACTION. I noticed it after setting flag
WIPHY_FLAG_HAVE_AP_SME in brcmfmac driver for my experiments.
This patch allows working with such drivers with just a small warning

This struct in the union is empty, but the design of using a zero-length
u8 array here is not fully compatible with C++ and can result in
undesired compiler warnings. Since there are no non-IE fields in the
Probe Request frames, get the location of the variable length IEs simply
by using the pointer to the frame header and the known header length.

Due to both <netinet/in.h> (in "utils/includes.h") and <linux/in6.h> (in
<linux/if_bridge.h>) being included, the in6_addr is being redefined:
once from the C library headers and once from the Linux kernel headers.
This causes some build failures with for example the musl C library:
In file included from /usr/include/linux/if_bridge.h:18,
from ../src/ap/vlan_init.c:17:
/usr/include/linux/in6.h:32: error: redefinition of 'struct in6_addr'
/usr/include/linux/in6.h:49: error: redefinition of 'struct sockaddr_in6'
/usr/include/linux/in6.h:59: error: redefinition of 'struct ipv6_mreq'
Mixing C library and Linux kernel headers is a bit problematic [1] and
should be avoided if possible [2]. In order to fix this, define just the
macros needed from <linux/if_bridge.h> as done in Busybox for the brctl
applet [3].

Commit 1889af2e0f ('VLAN: Separate station
grouping and uplink configuration') added an ap_sta_set_vlan() function
that gets called from pmksa_cache_auth.c. This broke CONFIG_IBSS_RSN=y
build if src/ap/sta_info.c did not get included in the build, i.e., if
CONFIG_AP=y was not set.
Fix this by making the ap_sta_set_vlan() call conditional on
CONFIG_NO_VLAN being undefined and define this for CONFIG_IBSS_RSN=y
builds. This is fine for wpa_supplicant since CONFIG_AP=y case was
already defining this. For hostapd, this function call is not needed for
CONFIG_NO_VLAN case either.

This patch add functionality of mesh SAE PMKSA caching. If the local STA
already has peer's PMKSA entry in the cache, skip SAE authentication and
start AMPE with the cached value.
If the peer does not support PMKSA caching or does not have the local
STA's PMKSA entry in the cache, AMPE will fail and the PMKSA cache entry
of the peer will be removed. Then STA retries with ordinary SAE
authentication.
If the peer does not support PMKSA caching and the local STA uses
no_auto_peer=1, the local STA can not retry SAE authentication because
NEW_PEER_CANDIDATE event cannot start SAE authentication when
no_auto_peer=1. So this patch extends MESH_PEER_ADD command to use
duration(sec). Throughout the duration, the local STA can start SAE
authentication triggered by NEW_PEER_CANDIDATE even though
no_auto_peer=1.

In scenarios where only DFS channels are available (e.g., outdoor,
special country codes), hostapd must be able to handle situations
where all are unavailable.
The two possibilities to get there are
1) while operating on the last available DFS channel a radar is
detected
2) hostapd is started while all channels are unavailable
In both cases, hostapd instead of terminating should better
wait for the NOPs to pass and re-try operation after the CAC.
This patch provides that feature by using the condition
(iface->state == HAPD_IFACE_DFS && !iface->cac_started)
as NOP mode signature to retry operation from within
hostapd_dfs_nop_finished().

Upon receiving FST setup request on old band, the peer is searched on
new band. The assumption is that MB IE from this peer on new band
previously received either in assoc event or in FST setup request.
There are cases in which above assumption doesn't work, peer is not
found and session setup fails. For example:
- STA connects over 11ac. Due to driver limitation, MB IE is not included
in assoc event
- STA connects over 11ad. MB IE included in assoc event.
- FST session established on 11ac band, with AP as initiator. i.e. FST
setup request sent in AP=>STA direction. STA searches for peer's (AP)
MB IE on 11ad band which exists.
- FST switch occur
- FST session established on 11ad band, with STA as initiator. i.e. FST
setup request sent in STA=>AP direction. AP searches for peer's (STA)
MB IE on 11ac band which are absent.
For fixing the above, consider also peers without MB IE as candidates in
the search algorithm.

There is a race condition in which AP might receive the EAPOL-Start
frame (from the just-associated station) before the TX completion of the
Association Response frame. This in turn will cause the EAPOL-Start

This tells to the server how long we have been trying to transmit the

determined from receive time (ignoring network delays and only at
accuracy of one second).
For interim updates, only value 0 is used since there are no
retransmissions of the same message. For other accounting messages, the
initial attempt goes out with value 0 and the retransmissions, if
needed, show the number of seconds the message has been waiting in the
queue.

If the AP is slow, passphrase hashing takes too long to serve the client
before timeout. Extend the Tunnel-Password design to allow a 64

Hashing takes quite some time (can be about one second on a low-power
CPU for each passphrase provided), so hostapd can easily hit the 900 ms
Wi-Fi client authentication deadline (mac80211 uses 3x 300 ms). This can
be fixed by storing the passphrase instead of PSK with the STA and defer
the hashing into the WPA/RSN 4-way handshake, when enumerating all PSKs.
This applies for the case where a RADIUS server is used to store the
per-STA passphrases and this passphrase is delivered as part of the MAC
ACL check during IEEE 802.11 Authentication frame processing.

A malicious station could try to do FT-over-DS with a non WPA-enabled
BSS. When this BSS is located in the same hostapd instance, internal RRB
delivery will be used and thus the FT Action Frame will be processed by
a non-WPA enabled BSS. This processing used to crash hostapd as
hapd->wpa_auth is NULL. If the target BSS is on a different hostapd
instance, it will not listen for these packets and thus not crash.
Fix this by checking hapd->wpa_auth before delivery.

The FT RRB hostapd packets have a length field. For PULL frames, it
counted the bytes starting with nonce and up to the last before pad. For
RESP frames, it counted the bytes starting with nonce and up to the last
before pad except for 2 bytes. For PUSH frames, it counted the bytes
starting with nonce and up to including pad.
As rounding is done with AES encryption, including pad does not make
sense. Not including the last field before pad does not make sense
either. These were broken in the earlier addition of the 2 octet
pairwise field in commit 1b484d60e5 ('FT:
Include pairwise cipher suite in PMK-R0 SA and PMK-R1 SA').
AES encryption is not affected, as rounding hides the differences. The
packets data_length field is not used, so the differences have no effect
there.
This patch changes the constants to match the bytes used, thus excluding
the pad. To validate the changes, look at remainder modulo 8 of the sum
of the size constants and the padding sizes.
