587b0457e0 LibreSSL: Fix build with LibreSSL
The changes needed for OpenSSL 1.1.0 had broken this since LibreSSL is
defining OPENSSL_VERSION_NUMBER in a manner that claims it to be newer
than the current OpenSSL version even though it does not support the
current OpenSSL API.

0daa9f6a13 EAP-TTLS peer: Fix success after fragmented final Phase 2 message
If the final Phase 2 message needed fragmentation, EAP method decision
was cleared from UNCOND_SUCC or COND_SUCC to FAIL and that resulted in
the authentication failing when the EAP-Success message from the server
got rejected. Fix this by restoring the EAP method decision after
fragmentation.

4653ceb750 nl80211: Report disassociated STA / lost peer for the correct BSS
We shouldn't use drv->ctx as it always points to the first BSS. When
using FullMAC driver with multi-BSS support it resulted in incorrect
treating nl80211 events. I noticed with with brcmfmac and BCM43602.

Before my change I was getting "disassociated" on a wrong interface:
wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: associated
wlan0-1: STA 78:d6:f0:00:11:22 WPA: pairwise key handshake completed (RSN)
wlan0: STA 78:d6:f0:00:11:22 IEEE 802.11: disassociated

With this patch it works as expected:
wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: associated
wlan0-1: STA 78:d6:f0:00:11:22 WPA: pairwise key handshake completed (RSN)
wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: disassociated

This doesn't apply to hostapd dealing with SoftMAC drivers when handling
AP SME & MLME is done it hostapd not the firmware.

21cb63fffd OpenSSL: Fix client certificate chain building after PKCS#12 use
If wpa_supplicant was first configured with PKCS #12 -based client
certificate chain and then used with another network profile that used a
different certificate chain from a X.509 certificate PEM file instead of
PKCS#12, the extra certificate chain was not reconstructed properly with
older versions of OpenSSL that 1.0.2. This could result in the
authentication failing due to the client certificate chain not being
complete or including incorrect certificates.

Fix this by clearing the extra certificate chain when setting up a new
TLS connection with OpenSSL 1.0.1. This allows OpenSSL to build the
chain using the default mechanism in case the new TLS exchange does not
use PKCS#12.

The following hwsim test case sequence was able to find the issue:
ap_wpa2_eap_tls_pkcs12 ap_wpa2_eap_tls_intermediate_ca_ocsp

a95cc47a92 ACS: Be more consistent with iface->current_mode checks
Offloading of ACS to the driver changed the design a bit in a way that
iface->current_mode could actually be NULL when the offloaded ACS
mechanism supports band selection in addition to channel selection. This
resulted in a combination that is too complex for static analyzers to
notice. While acs_init() can be called with iface->current_mode == NULL
that is only in the case where WPA_DRIVER_FLAGS_ACS_OFFLOAD is in use.
In other words, the actual ACS functions like acs_cleanup() that would
dereference iface->current_mode are not used in such a case.

Get rid of static analyzer warnings by explicitly checking
iface->current_mode in acs_init() for the case where ACS offloading is
not used.

64845c1f1a l2_packet: Extend bridge workaround RX processing to cover two frames
There was a race condition in how the l2_packet sockets got read that
could result in the same socket (e.g., non-bridge) to process both the
EAP-Success and the immediately following EAPOL-Key msg 1/4 instead of
each frame going in alternative order between the bridge and non-bridge
sockets. This could be hit, e.g., if the wpa_supplicant process did not
have enough CPU to process all the incoming frames without them getting
buffered and both sockets reporting frames simultaneously.

This resulted in the duplicated EAP-Success frame getting delivered
twice for processing and likely also the EAPOL-Key msg 1/4 getting
processed twice. While the latter does not do much harm, the former did
clear the EAP authentication state and could result in issues.

Fix this by extended the l2_packet Linux packet socket workaround for
bridge to check for duplicates against the last two received frames
instead of just the last one.

4a539abdbd l2_packet: Improve bridge workaround RX processing
It was possible for the packet socket on the bridge interface to receive
own transmitted frames between the bridge and non-bridge sockets
receiving the same incoming frame from a foreign host. This resulted in
the hash checksum validation step failing to notice a duplicate RX due
to the own frame updating the store hash value.

The own frame did get dropping in RX EAPOL processing, but that was too
late to address the issue with duplicate RX. Fix this by dropping own
frames already in l2_packet layer before checking and updating the last
RX hash value.

acc39435ff EAP-PEAP peer: Cryptobinding in fast-reconnect case with inner EAP
This was reported to fail with Windows 2012r2 with "Invalid Compound_MAC
in cryptobinding TLV". It turns out that the server decided to go
through inner EAP method (EAP-MSCHAPv2 in the reported case) even when
using PEAP fast-reconnect. This seems to be against the [MS-PEAP]
specification which claims that inner EAP method is not used in such a
case. This resulted in a different CMK being derived by the server (used
the version that used ISK) and wpa_supplicant (used the version where
IPMK|CMK = TK without ISK when using fast-reconnect).

Fix this interop issue by making wpa_supplicant to use the
fast-reconnect version of CMK derivation only when using TLS session
resumption and the server having not initiated inner EAP method before
going through the cryptobinding exchange.

cba9ebfdc2 P2P: Try SD Query with each non-ACK peer only once per search iteration
The previous behavior of bursting out all retry attempts of an SD Query
frame during a single search/listen iteration does not look very helpful
in the case where the peer does not ACK the query frame. Since the peer
was found in the search, but is not ACKing frames anymore, it is likely
that it left its listen state and we might as well do something more
useful to burst out a significant number of frames in hopes of seeing
the peer.

Modify the SD Query design during P2P Search to send out only a single
attempt (with likely multiple link-layer retries, if needed) per
search/listen iteration to each peer that has pending SD queries. Once
no more peers with pending queries remain, force another Listen and
Search phase to go through before continuing with the pending SD
queries.
