dfdabd917a RSN: Report completion only after IGTK configuration
Previously wpa_supplicant_key_neg_complete() was called before the
attempt to configure the IGTK received from the authenticator. This
could resulted in somewhat surprising sequence of events if IGTK
configuration failed since completion event would be followed by
immediate disconnection event. Reorder these operations so that
completion is reported only if GTK and IGTK are configurated
successfully.

Furthermore, check for missing GTK KDE in case of RSN and handle that
with an explicit disconnection instead of waiting for the AP to deliver
the GTK later.

eb3234c07b SAE: Use open authentication to reassociate for PMKSA caching
For reassociation with the same AP wpa_supplicant attempts to use cached
PMKSA. For this purpose PMKID is passed in RSNE in (Re)Association
Request frame. In the case of SAE AP, open authentication shall be used
during reassociation. Otherwise cached PMKID becomes invalid after full
SAE authentication.

The previous implementation correctly handles SME-in-wpa_supplicant
cases. However SME-in-driver cases, complete SAE authentication is
performed. As a result, first reassociation attempt fails.

Fix SME-in-driver behavior by reseting authentication algorithm to
WPA_AUTH_ALG_OPEN when reassociating with SAE AP with an existing PMKSA
cache entry.

fe01cd0067 Fix FILS ERP association event with 4-way HS offload drivers
When FILS authentication is used with ERP, no EAPOL frames are expected
after association. However, for drivers that set the
WPA_DRIVER_FLAGS_4WAY_HANDSHAKE_8021X capability flag, the EAP state
machine was not configured correctly and was waiting for EAPOL frames,
which leads to disconnection.

Fix this by reordering the if branches to set the EAPOL/EAP state
machines to success when FILS authentication was already completed.

323a51cc01 nl80211: Handle NL80211_CMD_PROBE_CLIENT command response
When processing the NL80211_CMD_PROBE_CLIENT command response, the
nl80211 layer in the kernel sends a response containing the cookie
associated with the client probe request. This response was not handled
by driver_nl80211.c when sending the command, and it was mistakenly
handled as an asynchronous event. This incorrect event did not include
the MAC/ACK attributes, so it was ignored in practice, but nevertheless,
the command response should not be processed as an event.

Fix this by reading the response as part of the sending the command
flow.

710c692381 P2PS: Cleanup pending_p2ps_group flag
pending_p2ps_group flag is not always cleaned, which may later result
in an unexpected GO bring up, after PD response is transmitted in
wpas_prov_disc_resp_cb().
This can be seen when running the following hwsim tests together:
 - p2ps_channel_sta_connected_disallow_freq_mcc
 - p2ps_channel_active_go_and_station_different_mcc
Fix this by clearing pending_p2ps_group flag also when processing new
PD requests. In addition, set this flag only when really needed.

0be8b9238f mka: Avoid memory leak in unexpected case in RECEIVE
It looks like it is possible for the RECEIVE state to leak memory where
a previously allocated sm->lki is moved to sm->oki while sm->oki is
pointing to not yet freed entry. It is not clear how this can be
triggered, but it has come up in hwsim testing under heavy load.

Free sm->oki if it is still set in RECEIVE before replacing it with
sm->lki to avoid this memory leak.

This fixes some issues where bss->freq could have been used to replace

bss->freq has not been consistently used to track the current operating
channel in station mode, so it should not be trusted for this type of
uses. Clearing it makes this a bit more robust by at least avoiding the
cases of information from past association being used.

greater than 1, so these checks are unreachable and for all cases, the
cofactor is known to be 1. Furthermore, RFC 5931 explicitly disallow use

needed for any curve that is compliant with the RFC.
