84972999ba FT: More debug prints for RSNE modification for EAPOL-Key msg 2/4
This buffer was getting corrupted, so add more details to make it
clearer what causes the corruption should this type of regression show
up again.

4cfa8b92ba Fix wpa_insert_pmkid() when buffer includes extra IEs
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.

07fe134d9c EAP-SIM peer: Do not accept SIM/Challenge without SIM/Start
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.

b2e2a8588d OpenSSL: Extend key_block size determination to support GCM/CCM ciphers
These ciphers do not use a separate MAC algorithm, so digest nid will be
NID_undef. In addition, the fixed_iv_length needs to be set to 4 which
is the implicit part of the IV from PRF. This is needed to fix EAP-FAST
key derivation for cases where GCM/CCM ciphers are used for TLS.

307cfc3286 Strip trailing zero data in EAPOL-Key msg 1/4 when no PMKID to send
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).

2c5ccfa607 nl80211: Initialize full channel info struct even if channel is not known
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.

e6d3aca9cf WPS: Add prefixes to public event_* functions
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_)

Tested via (among other things) hwsim '-f ap_wps' module.

996662250d P2P: Add support for EDMG channels
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.

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.
