bcce934755 dbus: Restrict DeviceName size to 32 characters in setter
The maximum WPS Device Name length is 32 characters and that limit was
already enforced for the control interface and configuration files.

5a38a7fe43 tests: Roam between two WPA2-PSK APs and try to hit a disconnection race
This is a regression test case for hostapd bug where the
disconnection/deauthentication TX status callback timeout could be
forgotten after new association if no ACK frame was received and the STA
managed to reconnect within two seconds.

9e8fde2134 AP: Fix Deauth/Disassoc TX status timeout handling
The ap_sta_deauth_cb and ap_sta_disassoc_cb eloop timeouts are used to
clear a disconnecting STA from the kernel driver if the STA did not ACK
the Deauthentication/Disassociation frame from the AP within two
seconds. However, it was possible for a STA to not ACK such a frame,
e.g., when the disconnection happened due to hostapd pruning old
associations from other BSSes and the STA was not on the old channel
anymore. If that same STA then started a new authentication/association
with the BSS, the two second timeout could trigger during this new
association and result in the STA entry getting removed from the kernel.

Fix this by canceling these eloop timeouts when receiving an indication
of a new authentication or association.

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.
