P2P: Skip GO Neg Conf ack failure workaround of send failures The workaround to ignore no ctrl::ack received for GO Negotiation Confirmation frame was only supposed to be used when the frame was actually transmitted and just the ack was not received. However, due to the way the driver failure on transmitting the frame were reported, this ended up getting applied for all failures in sending the GO Negotiation Confirmation frame. Improve this by providing a mechanism to indicate whether send_action operations fail locally before the frame was actually transmitted or because of not receiving ack frame after having transmitted the frame.

P2P: Do not perform P2P GO CS in some cases A P2P GO channel switch should not be triggered in all cases that require channel list update. Specifically, a P2P GO CS should not be triggered in case that the P2P GO state changed or in case that that the P2P GO has just completed a CS. To fix this, add reason code to wpas_p2p_channel_list_update() and trigger CS flow only for the relevant cases. Signed-off-by: Ilan Peer <ilan.peer@intel.com>

P2P: Use only the -m config for P2P management device Previously, the case of non-netdev P2P management device ended up pulling in both the main interface (e.g., wlan0) and P2P Device interface (from command line -m argument) as configuration. Similarly, the main interface ended up included both configuration files. This is not really helpful for various use cases, e.g., when permanent P2P group information is stored in the P2P Devince interface, but it gets duplicated in the main station interface configuration. Clean this up by changing the -m<file> argument to replace, not concatenate, configuration information. In other words, the main station interface will not read this configuration and the P2P Device interface (non-netdev) does not read parameters from the station interface configuration file.

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.

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.

Fix disconnection event processing Commit 0d30cc240fa36905b034dc9676f9d8da0ac18e56 forced wpa_s->current_ssid and wpa_s->key_mgmt to be cleared in wpa_supplicant_mark_disassoc() which gets called from wpa_supplicant_event_disassoc(). This broke IEEE 802.1X authentication failure processing and P2P deauthentication notification (group termination). Fix this by splitting wpa_supplicant_event_disassoc() into two parts and make wpas_p2p_deauth_notif() indicate whether the interface was removed. If so, the last part of disassocition event processing is skipped. Since the wpa_supplicant_mark_disassoc() call is in the second part, the above mentioned issues are resolved. In addition, this cleans up the P2P group interface removal case by not trying to use fast reconnection mechanism just before the interface gets removed.

P2P: Add event messages for possible PSK failures on P2P groups It is possible for the GO of a persistent group to change the PSK or remove a client when per-client PSKs are used and this can happen without the SSID changing (i.e., the group is still valid, but just not for a specific client). If the client side of such persistent group ends up trying to use an invalidated persistent group information, the connection will fail in 4-way handshake. A new WPS provisioning step is needed to recover from this. Detect this type of case based on two 4-way handshake failures when acting as a P2P client in a persistent group. A new "P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to indicate when this happens. This makes it easier for upper layers to remove the persistent group information with "REMOVE_NETWORK <persistent group id>" if desired (e.g., based on user confirmation). In addition to indicating the error cases for persistent groups, all this type of PSK failures end up in the client removing the group with the new reason=PSK_FAILURE information in the P2P-GROUP-REMOVED event.

Fix this by using an eloop timeout to free remove the P2P group so that wpa_supplicant_create_ap() and especially wpa_supplicant_associate() callers do not need to know about interface getting possibly removed. In addition, move the P2P specific code into p2p_supplicant.c where it really belongs. This allows the already existing group formation timeout to be used by reducing the timeout to zero.

P2P: Support random device address To enhance privacy, generate a random device address for P2P interface. If there is no saved persistent group, it generate a new random MAC address on bringing up p2p0. If there is saved persistent group, it will use last MAC address to avoid breaking group reinvoke behavior. There are two configurations are introduced: * p2p_device_random_mac_addr enable device random MAC address feature, default disable. * p2p_device_persistent_mac_addr store last used random MAC address.

P2P: Add rx_freq parameter to Probe Request frame handler In some cases, Probe Request frames can be received by a peer not only on a listen channel. In this case an additional rx_freq parameter explitly contains a Probe Request frame RX frequency. In case rx_freq is set to 0, a Probe Request frame RX channel is assumed to be our own listen channel (p2p->cfg->channel).

P2P: Do not perform P2P GO CS in some cases A P2P GO channel switch should not be triggered in all cases that require channel list update. Specifically, a P2P GO CS should not be triggered in case that the P2P GO state changed or in case that that the P2P GO has just completed a CS.

P2P: Add event messages for possible PSK failures on P2P groups It is possible for the GO of a persistent group to change the PSK or remove a client when per-client PSKs are used and this can happen without the SSID changing (i.e., the group is still valid, but just not for a specific client). If the client side of such persistent group ends up trying to use an invalidated persistent group information, the connection will fail in 4-way handshake. A new WPS provisioning step is needed to recover from this. Detect this type of case based on two 4-way handshake failures when acting as a P2P client in a persistent group. A new "P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to indicate when this happens. This makes it easier for upper layers to remove the persistent group information with "REMOVE_NETWORK <persistent group id>" if desired (e.g., based on user confirmation). In addition to indicating the error cases for persistent groups, all this type of PSK failures end up in the client removing the group with the new reason=PSK_FAILURE information in the P2P-GROUP-REMOVED event.

P2P: Fix crash when failed to create GO interface wpa_supplicant crashes if driver configuration for AP mode interface configuration fails after group negotiation. This is because of a regression from commit 1075b2957169d8f9d6dddd7679339c751dc9515b that ends up freeing the wpa_s instance from within wpa_supplicant_create_ap() without the caller knowing. Fix this by using an eloop timeout to free remove the P2P group so that wpa_supplicant_create_ap() and especially wpa_supplicant_associate() callers do not need to know about interface getting possibly removed. In addition, move the P2P specific code into p2p_supplicant.c where it really belongs. This allows the already existing group formation timeout to be used by reducing the timeout to zero.
