In repeater configuration, both AP and STA wireless interfaces may be
included into the same bridge. In this case the following race condition
may occur: wpa_supplicant and hostapd are started, then hostapd clients
are connected before wpa_supplicant connects to remote AP. EAPOL packets
between hostapd and its clients are detected by wpa_supplicant on bridge
interface, prematurely disabling the workaround.
One possible option to fix this issue is to check EAPOL destination MAC
in wpa_supplicant and disable workaround only if EAPOL packet on bridge
interface is indeed intended for wpa_supplicant.

The RECONNECT command on the station was issued immediately after
wpa_supplicant had processed EAPOL-Key msg 3/4. This could happen before
hostapd has processed EAPOL-Key msg 4/4 and especially with UML
time-travel, this could result in the following FT protocol exchange
going through in a manner that makes the hostapd process EAPOL-Key msg
4/4 from the first association as a postponed EAPOL RX at the beginning
of the second association. Avoid this by waiting hostapd to report
completion of the connection before issuing RECONNECT.

The case where the old RSNE included one or more PMKIDs and that RSNE
was followed by another IE was handled incorrectly since the
os_memmove() to move the end of the buffer when removing old PMKIDs was
stopping copying at the end of the RSNE, not the end of the IE buffer.
This could result in corrupting the IE that followed the RSNE. In
practice, this broke FT-SAE with H2E by corrupting the RSNXE that is in
the buffer after the RSNE.
Fix this by copying the full end of the buffer (i.e., including the
following RSNXE in the visible error case) when removing the old PMKIDs.

EAP-SIM full authentication starts with one or more SIM/Start rounds, so
reject an unexpected SIM/Challenge round without any preceeding
SIM/Start rounds to avoid unexpected behavior. In practice, an attempt
to start with SIM/Challenge would have resulted in different MK being
derived and the Challenge message getting rejected due to mismatching
AT_MAC unless the misbehaving server has access to valid Kc, so the end
result is identical, but it is cleaner to reject the unexpected message
explicitly to avoid any risk of trying to proceed without NONCE_MT.

EAPOL-Key message 1/4 without PMKID KDE was sent with 22 bytes of stray
data following a zero length key data field. These 22 bytes happens to
be the exact size of an PMKID KDE. Strip these trailing bytes by
checking whether a PMKID is available and adjust pmkid_len to 0 if not.
This was seen for example in capture files created by hwsim test case
suite_b_192 but code modified to handle also the other cases without
PMKID (Suite B no-KCK, FILS without PMKID available, SAE without PMKID
available).

It was possible for the driver to advertise support for channels that
are not found from wpa_supplicant frequency-to-channel mapping (e.g.,
channel 182 at 5910 MHz) and that resulted in not initializing the
channel number information. Fix this by explicitly clearing the full
struct hostapd_channel_data buffer before parsing the information into
it from the driver.
This avoids some conditional jumps that could have dependent on
uninitialized values.

openssl engines may dynamically load external libraries. Our event_*()
functions happen to be named very generically, such that event_add()
collides with the libevent library (https://libevent.org/). This can
have disastrous effects (esp. when using CONFIG_WPA_TRACE, which enables
partial linking) when our SSL engines call into the WPS event_add()
instead of their intended libevent event_add().
Resolve this by providing a more unique prefix to these functions.
Rename performed via:
sed -i -E \
's:\<event_(add|delete_all|send_all_later|send_stop_all)\>:wps_upnp_event_\1:g' \
$(git grep -l event_)

This allows a P2P connection over P802.11ay EDMG channels to achieve the
highest link speed that the standard allows for channel bonding (CB) up
to CB4.
Let each P2P peer add its EDMG channels to the Supported Channels IE
advertised in P2P GO negotiation. Give EDMG channels priority when peers
negotiate for operating channel.
User may add 'edmg' parameter to p2p_connect, p2p_add_group, and
p2p_invite commands to prefer an EDMG channel for the P2P link. User may
also set p2p_go_edmg=1 in wpa_supplicant configuration file to prefer
EDMG.
When EDMG is used, P2P will try to find the highest channel bonding
supported channel that matches the frequency parameter, if the devices
do not support EDMG, the P2P connection will use a legacy (1-6) 60 GHz
channel.
