Jouni Malinen 2cd0758441 P2P: Allow peer to propose channel in invitation process
Make Invitation process for re-invoking a persistent group behave
similarly to GO Negotiation as far as channel negotiation is concerned.
The Operating Channel value (if present) is used as a starting point if
the local device does not have a forced operating channel (e.g., due to
concurrent use). Channel lists from devices are then compared to check
that the selected channel is in the intersection. If not, channel is
selected based on GO Negotiation channel rules (best channel preferences
etc.). Invitation Request is rejected if no common channel can be
selected.

As long as WLAN_STA_ASSOC_REQ_OK is set in sta->flags, Class 3 frames do
not trigger a disassoc/deauth. If it is still set even after the assoc
response tx has already failed, it may take somewhat longer for clients
to realize that the connection wasn't fully established.

Jouni Malinen 802bc4211b Fix AES block size handling for internal cipher
AES uses the same 128-bit block size with 128, 192, 256 bit keys, so use

block size based on key length. This fixes use of 192-bit and 256-bit
AES keys with crypto_cipher_*() API when using the internal AES
implementation.

Arik Nemtsov 4425645113 AP: Configure basic rates from iface and not conf
The conf doesn't contain any basic rates in some cases. Most notably,
when starting a P2P GO in 5 GHz. Use the iface rates which are
initialized in hostapd_prepare_rates() to the conf rates or set to

commit e5693c4775.

Jouni Malinen a05126d620 WFD: Properly match group for WFD element in Invitation Response
The group matching should be done by comparing the P2P Interface Address
(which the group_bssid here is) to the group's BSSID and not the group
ID (which uses P2P Device Address and would have also needed the SSID).
Though, it should be noted that this case cannot really happen since a
GO in an active group would never be invited to join another group in
its GO role (i.e., if it receives an Invitation Request, it will reply
in P2P Device role). As such, this fix does not really change any
observable behavior, but anyway, it is good to keep the implementation
here consistent with the Invitation Request case.

Since the EAP-SIM/AKA identities are ASCII strings, there is no need to

strict about enforcing username (i.e., no realm part) to be used in the

of the types to be used as the key in the pseudonym and reauth
operations. This allows simpler lookup operations to be used.
