P2P: Allow multiple scan runs to find GO for p2p_connect join If the GO is not found, we cannot send Provisioning Discovery Request frame and cannot really connect anyway. Since the Provisioning Discovery is a mandatory part, it is better to continue join-scan until the GO is found instead of moving to the next step where normal connection scan is used (PD would not be used from there). Use a limit of 10 scan attempts for p2p_connect join to avoid getting in infinite loop trying to join. If the GO is not found with those scans, indicate failure (P2P-GROUP-FORMATION-FAILURE) and stop the join attempt.

P2P: Use hardcoded idle timeout of 10 seconds in P2P client role The p2p_group_idle configuration parameter is much more useful for GO role, so use a separate hardcoded value of 10 seconds in P2P client role. In practice, this means that the P2P client role will automatically tear down the group when the GO tears down the group. The 10 second timeout is enough to recover from temporary disconnections without unnecessary tearing down the group if the GO is still present and allows the client to connect.

P2P: Extend use of group formation timeout until end of 4-way handshake Instead of relying on the P2P group idle timeout before the group connection has been fully established, re-start the group formation timeout in the end of the WPS provisioning step and clear it at the successful completion of the initial 4-way handshake. This allows the P2P group idle timeout to be set to a small value without triggering it during the initial scan and connection attempt. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

P2P: Use 500 ms search delay by default during concurrent operations If the p2p_find command is used without the delay parameter, a 500 ms default search delay will now be used when any interface using the same radio is in an concurrent operation.

P2P: Add automatic GO Negotiation vs. join-a-group selection p2p_connect command can now be used with an optional "auto" parameter to request wpa_supplicant to determine automatically whether to use join-a-group operation (if the peer is operating as a GO) or group formation. This makes it easier for external programs to handle connection type selection by offloading this to wpa_supplicant. The previously used p2p_connect join commands can be replaced with p2p_connect auto to use this new mechanism. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

P2P: Add mechanism for timing out idle groups A new configuration parameter, p2p_group_idle, can now be used to set idle timeout value for P2P groups in seconds (0 = no timeout). If set, this values is used to remove P2P group (both GO and P2P client) interfaces after the group has been idle (no clients/GO seen) for the configuration duration. The P2P-GROUP-REMOVED event is now indicating the reason for group removal when known. For example: P2P-GROUP-REMOVED wlan0 GO reason=REQUESTED P2P-GROUP-REMOVED wlan1 client reason=IDLE

P2P: Cancel group formation timeout on group removal (on client) Group formation timeout is normally canceled when 4-way handshake is completed (WPA_COMPLETED -> wpas_p2p_completed). However, it is possible for the GO to stop the group before this happens (i.e., send Deauthentication frame with reason code 3 before 4-way handshake is completed). This resulted in the group getting removed, but the group formation timeout left behind. The unexpected timeout may then result in undesired termination of the following operation. Fix this by canceling the group formation timeout in wpas_p2p_group_delete() similarly to how group idle timeout was canceled there. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

P2P: Allow older scan results to improve p2p_connect-auto robustness Previusly the peer was assumed to not be operating a GO if the BSS entry for it was not updated in the single scan run started by p2p_connect-auto. This is not very robust since a scan may miss the peer if either a Probe Request or Probe Response frame is lost. Improve robustness by assuming the peer is still operating the GO and starting the join operation. If the GO is not found during PD-for-join or the single-channel scans during the join, fall back to GO Negotiation. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

P2P: Avoid extra group interface creation on GO reinvocation If separate group interfaces are used, the pending group interface got removed unnecessarily when stopping find operations when accepting an invitation to reinvoke the group in GO role.

The default behavior is to try to start any new P2P group on an operating channel that is already in use on another virtual interface to avoid extra cost from hopping between multiple channels. If this new parameter is set to 1, such preference is not used and instead, the channel for the new P2P group is selected based on other preferences while ignoring operating channels of any concurrent connection.

P2P: Fix group idle timer cancellation on group removal The wpas_p2p_group_idle_timeout was getting cancelled in the beginning of wpas_p2p_group_delete(). However, in the case of P2P client role, this function called wpa_supplicant_deauthenticate() next and that ended up changing state to WPA_DISCONNECTED which resulted in wpas_p2p_notif_disconnected() rescheduling the timeout. This left the unexpected timeout behind after the group was removed. If another group operation was started within P2P_MAX_CLIENT_IDLE (10) seconds, that timeout could end up terminating the group while it was still being set up. Fix this by reordering wpas_p2p_group_delete() to cancel the group idle timeout only after having called wpa_supplicant_deauthenticate(). The group idle timeout is still rescheduled, but it gets removed immediately afterwards when the actual group information is being cleared. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

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: Update D-Bus network object semantics during group formation Do not emit network objects during P2P group formation since such network objects can confuse certain apps. Instead, a persistent group object is created to allow apps to keep track of persistent groups. Persistent group objects only represent the info needed to recreate the group. Also fixes a minor bug in the handling of persistent group objects during WPS operations. Signed-off-by: Jayant Sane <jayant.sane@intel.com>

Stop sched_scan in number of cases where it should not be running When a P2P group is removed, we better not leave possibly started sched_scan running. This could happen when a separate group interface was not used. In addition, it looks safer to explicitly stop sched_scan before starting P2P Listen or Find operations to make sure the offloaded scanning is not running when doing similar P2P operations.

P2P: Clear sta_scan_pending on group removal It is possible for the P2P client group to be removed while waiting for a pending scan operation (e.g., when p2p_group_idle timeout hits after getting disconnected from the GO with something else than Deauthentication with reason code 3). If this happens with a P2P interface that is used both for P2P Device and group roles, scan state could get stuck while waiting for the next scan to complete since no more station (P2P client) mode scans are scheduled. Fix this by clearing sta_scan_pending when removing the temporary group network block. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

P2P: Wait for PD-before-join response Even though the Provision Discovery Response frame from PD-before-join does not really provide any additional information, it can be better to wait for it before starting the join operation. This adds a minimal extra latency in the most common case and cleans up the sequence of driver operations and debug log by avoiding potential processing of the Provision Discovery Response while already running a scan for the actual connection. If transmission of Provision Discovery Request fails, join operation is started without the additional wait. In addition, a new timeout is used to start the join if Provision Discovery Response is lost for any reason. Signed-hostap: Jouni Malinen <j@w1.fi>

P2P: Allow PSK to be used instead of passphrase for persistent GO This continues optimizations for use of CPU heavy pbkdf2_sha1() in GO setup after the earlier commit 30c371e8a54c3b1bece6366ff0666da15d63e45e by allowing PSK to be used instead of passphrase when creating persistent group information manually for the GO. It should be noted that this would not meet the requirements in the P2P specification (GO shall maintain the passphrase), so this should be used only when there is no need to allow manual configuration of legacy STAs using the passphrase.

Add p2p_go_max_inactivity config option This enables setting a different max inactivity timeout for P2P GO. This timeout is used to detect inactive clients. In some scenarios it may be useful to have control over this and set a shorter timeout than the default 300s. For example when running STA and P2P GO interfaces concurrently, the STA interface may perform scans which may cause the GO to miss a disassoc / deauth frames from a client and keep assuming that the client is connected until the inactivity detection kicks in. 300 secs is a bit too long for such scenarios and creates a bad user experience.

P2P: Allow older scan results to improve p2p_connect-auto robustness Previusly the peer was assumed to not be operating a GO if the BSS entry for it was not updated in the single scan run started by p2p_connect-auto. This is not very robust since a scan may miss the peer if either a Probe Request or Probe Response frame is lost. Improve robustness by assuming the peer is still operating the GO and starting the join operation. If the GO is not found during PD-for-join or the single-channel scans during the join, fall back to GO Negotiation. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

P2P: Retry PD Request in join-a-running-group case The GO may be in sleep when we send a PD Request frame to indicate that we are about to join a running group. Previously, this frame was not retried more than normal low level retries. This can result in the GO not getting the frame especially in cases where concurrent multi-channel operations or aggressive sleep schedule is used since most drivers do not yet synchronize with the GO's NoA before association. Increase the likelihood of the GO receiving the PD Request frame by retransmitting it similarly to the PD-for-GO-Negotiation case. Start the actual join operation only after these retries have failed to get an acknowledgment from the GO to give the connection attempt a chance to succeed if the driver implements better NoA synchronization for it.

P2P: Improve robustness against lost ctrl::ack frames P2P includes two use cases where one of the devices is going to start a group and likely change channels immediately after processing a frame. This operation may be fast enough to make the device leave the current channel before the peer has completed layer 2 retransmission of the frame in case the ctrl::ack frame was lost. This can result in the peer not getting TX status success notification. For GO Negotiation Confirm frame, p2p_go_neg_conf_cb() has a workaround that ignores the TX status failure and will continue with the group formation with the assumption that the peer actually received the frame even though we did not receive ctrl::ack. For Invitation Response frame to re-invoke a persistent group, no such workaround is used in p2p_invitation_resp_cb(). Consequently, TX status failure due to lost ctrl::ack frame results in one of the peers not starting the group. Increase the likelihood of layer 2 retransmission getting acknowledged and ctrl::ack being received by waiting a short duration after having processed the GO Negotiation Confirm and Invitation Response frames for the re-invocation case. For the former, use 20 ms wait since this case has been worked around in deployed devices. For the latter, use 50 ms wait to get even higher likelihood of getting ctrl::ack through since deployed devices (and the current wpa_supplicant implementation) do not have a workaround to ignore TX status failure. 20 ms is long enough to include at least couple of retries and that should increase likelihood of getting ctrl::ack through quite a bit. The longer 50 ms wait is likely to include full set of layer 2 retries. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

The first two parameters are given in units of 100 TUs (102.4 ms). The third parameter can be used to further limit the interval into a specific TU amount. If it is set to -1, no such additional limitation is enforced. It should be noted that the P2P specification describes the random Listen state interval to be in units of 100 TUs, so setting the max TU value to anything else than -1 is not compliant with the specification and should not be used in normal cases.

P2P: Add option to force SSID/passphrase for GO Negotiation An existing persistent group information can now be used to force GO Negotiation to use the previously used SSID/passphrase from a persistent group if we become a GO. This can be used as an alternative to inviting a new P2P peer to join the group (i.e., use GO Negotiation with GO intent 15 instead of starting an autonomous GO and using invitation), e.g., in case a GO Negotiation Request is received from a peer while we are not running as a GO. The persistent group to use for parameters is indicated with persistent=<network id> parameter to p2p_connect. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

P2P: Allow multiple scan runs to find GO for p2p_connect join If the GO is not found, we cannot send Provisioning Discovery Request frame and cannot really connect anyway. Since the Provisioning Discovery is a mandatory part, it is better to continue join-scan until the GO is found instead of moving to the next step where normal connection scan is used (PD would not be used from there). Use a limit of 10 scan attempts for p2p_connect join to avoid getting in infinite loop trying to join. If the GO is not found with those scans, indicate failure (P2P-GROUP-FORMATION-FAILURE) and stop the join attempt.

P2P: Fix shared frequency preference for concurrent operations Commit 50285f5ca8086cca45afa42cd23c3a3c1cd58f40 changed number of rules in channel selection and among other things, it broke the design where the currently used operating channel on a virtual interface that is shared by the same radio is preferred to avoid costs related to multi-channel concurrency. Fix this regression by making the P2P module aware of the shared channel and using that preference as the highest priority when re-selecting the channel during negotiation.

Pass signal strength through, fix units The signal strength is currently never used as the only driver reporting it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never populated by the kernel. The kernel will (soon) populate IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that. Also, since it was never really populated, we can redefine the signal field to be in dBm units only. My next patch will also require knowing the signal strength of probe requests throughout the code (where available), so add it to the necessary APIs.

DBus: Add ability to report probe requests Some applications require knowing about probe requests to identify devices. This can be the case in AP mode to see the devices before they connect, or even in P2P mode when operating as a P2P device to identify non-P2P peers (P2P peers are identified via PeerFound signals). As there are typically a lot of probe requests, require that an interested application subscribes to this signal so the bus isn't always flooded with these notifications. The notifications in DBus are then unicast only to that application. A small test script is also included. Signed-hostap: Johannes Berg <johannes.berg@intel.com>

Allow this process to be used more easily by automatically authorizing the peer that we tried to invite to use this second invitation sequence even if persistent_reconnect=0. For this mechanism to work, the device that starts the invitation needs to start listen mode to be able to receive the invitation request from the peer. At least for now, this is not done automatically, but future changes could potentially enable this automatically at least if there are no concurrent operations in progress.

P2P: Fix shared frequency preference for concurrent operations Commit 50285f5ca8086cca45afa42cd23c3a3c1cd58f40 changed number of rules in channel selection and among other things, it broke the design where the currently used operating channel on a virtual interface that is shared by the same radio is preferred to avoid costs related to multi-channel concurrency. Fix this regression by making the P2P module aware of the shared channel and using that preference as the highest priority when re-selecting the channel during negotiation.

P2P: Fix group formation timeout on GO during WPS step Commit 361cdf34009c7407ddf22dee6f5e6ce82e81bcae changed the way the group formation timeout is used on P2P client. However, it resulted in clearing the timeout on the GO when the GO started beaconing. This is not correct since the timeout is supposed to be maintained until at least the completion of the WPS provisioning step. Fix this regression by clearing the timeout here only in the case we are not GO in group formation phase. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

P2P: Use hardcoded idle timeout of 10 seconds in P2P client role The p2p_group_idle configuration parameter is much more useful for GO role, so use a separate hardcoded value of 10 seconds in P2P client role. In practice, this means that the P2P client role will automatically tear down the group when the GO tears down the group. The 10 second timeout is enough to recover from temporary disconnections without unnecessary tearing down the group if the GO is still present and allows the client to connect.

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: Do not request station mode scans during P2P operations The P2P search mechanism depends on the same scan functionality that is used for station mode scans. If these operations are being used at the same time, scan result processing is not handled properly. Avoid unexpected behavior by delaying station mode scan requests if a P2P operation is in progress. Among other things, this allows the station mode connection attempt to be continued after a P2P find or group formation has been completed if the interface is available (i.e., when the P2P group uses a separate virtual interface).
