* P2P: Handle P2P Device dedicated interface parent removalIlan Peer2015-06-191-0/+30
| | | | | | | | | | | | | | | | | In case of a network interface removal, check if the interface was also the parent interface of the P2P Device dedicated interface. If this is the case, then stop the P2P Device functionality, and remove the P2P Device dedicated interface. In case that the interface is added again and P2P Device functionality can be enabled again, add a new P2P Device dedicated interface and allow further P2P Device functionality. In case that the P2P Device dedicated interface is re-created, the original P2P Device configuration file is needed, so store it in the global params (instead in the wpa_interface configuration).

* P2P: Add rx_freq parameter to Probe Request frame handlerMax Stepanov2015-06-141-0/+2
| | | | | | | | | | | 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).

* Add support for CONFIG_NO_ROAMING to MakefileLauri Hintsala2015-03-291-0/+2
| | | | | | | | | | Commit e9af53ad39a19264bf5307a1b5923afc2b2f9b06 introduced new CONFIG_NO_ROAMING configuration parameter but unfortunately it was added only to Android.mk. Enabling this parameter didn't have any effect when Makefile was used to build wpa_supplicant. This commit fixes that problem and cleans "unused variable" compiler warning.

* Allow PSK/passphrase to be set only when neededJouni Malinen2015-03-281-2/+22
| | | | | | | | | | | | | | | | | | | | | The new network profile parameter mem_only_psk=1 can be used to specify that the PSK/passphrase for that network is requested over the control interface (ctrl_iface or D-Bus) similarly to the EAP network parameter requests. The PSK/passphrase can then be configured temporarily in a way that prevents it from getting stored to the configuration file. For example: Event: CTRL-REQ-PSK_PASSPHRASE-0:PSK or passphrase needed for SSID test-wpa2-psk Response: CTRL-RSP-PSK_PASSPHRASE-0:"qwertyuiop" Note: The response value uses the same encoding as the psk network profile parameter, i.e., passphrase is within double quotation marks.

* nl80211: Allow driver-based roam to change ESSKrishna Vamsi2015-03-241-1/+22
| | | | | | | This extends NL80211_CMD_ROAM event processing to allow the driver to roam to another ESS (different SSID) when using offloaded BSS selection. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
* Delay AP selection if all networks are temporarily disabledAvraham Stern2015-03-221-0/+66
| | | | | | | | | | If all networks are temporarily disabled, delay AP selection until at least one network is enabled. Running AP selection when all networks are disabled is useless as wpa_supplicant will not try to connect. In addition, it will result in needless scan iterations that may delay the connection when it is needed. Signed-off-by: Avraham Stern <avraham.stern@intel.com>
* Restart sched_scan on channel list changeVictor Goldenshtein2015-03-201-0/+8
| | | | | | | | | | | | | The channel list can be changed as a result of arriving beacon hints during normal scan or as a result of local Reg-Domain change. Some passive channels can become active and needs to be reconfigured accordingly for the scheduled scan. This fixes the connection to hidden SSIDs on 5 GHz band during default Reg-Domain 00 (world roaming).

* Make rate-not-supported debug print more usefulJouni Malinen2015-03-071-3/+4
| | | | | | | | | It looks like "hardware does not support required rate 1.0 Mbps" has started showing up in some hwsim test cases as a reason for failure. This should not really occur with mac80211_hwsim, so add more details to the debug print to make it easier to figure out what exactly happened. Signed-off-by: Jouni Malinen <j@w1.fi>
* TDLS: Allow driver to request TDLS Discovery Request initiationSunil Dutt2015-03-061-0/+4

* Do not add blacklist entries based on normal disconnect request casesJouni Malinen2015-03-011-0/+3
| | | | | | | | | | There are number of cases where wpa_supplicant requests the current connection to be disconnected before starting a new operation. Such cases do not really indicate that there was an error in connecting or a disconnection initiated by the AP, so do not add a temporary blacklist entry in such sequences. Signed-off-by: Jouni Malinen <j@w1.fi>
* P2P: Do not allow scan or normal association on cfg80211 P2P DeviceJouni Malinen2015-03-011-0/+3
| | | | | | | | | | The dedicated P2P management instance (wpas->p2p_mgmt == 1) using cfg80211 P2P Device cannot be used for non-P2P uses or connection (there is no netdev). Reject or ignore such operations to avoid unexpected operations if enabled network blocks are configured in the wpa_supplicant instance used to control this interface.

* Use estimated throughput to improve roaming selectionJouni Malinen2015-02-221-4/+14
| | | | | | | | | | | | | | Previously, within-ESS roaming was skipped if the selected BSS did not have a higher signal strength than the current BSS regardless of AP capabilities. This could result in not moving to a BSS that would provide higher throughput, e.g., due to larger channel bandwidth or higher rates (HT/VHT MCS). Use estimated throughput information from scan result processing to allow within-ESS roaming if the selected BSS is likely to provide better throughput even if the current BSS has larger RSSI. Signed-off-by: Jouni Malinen <j@w1.fi>
* Update current BSS level when signal change event occursMatthieu Mauger2015-02-211-0/+2
| | | | | | | | | | | | | | | When an EVENT_SIGNAL_CHANGE occurs the bgscan is informed about this change but the new RSSI value is not stored. In consequence, when roaming candidates are evaluated, the RSSI value of the current BSS used to compare is an old one obtained during the last scan rather than the new one given by the signal change event. This leads sometimes to bad decision when selecting a new BSS for roaming. This patch solves the issue by updating the current BSS level when receiving a signal change event in order to have a very up-to-date current signal value when choosing an new BSS.

* wpa_supplicant: Cancel sched_scan when stopping countermeasuresIlan Peer2015-02-211-0/+9
| | | | | | | | | | When stopping the TKIP countermeasures, it would be preferable to connect immediately. However if scheduled scan is in progress, a connection attempt will be done only when scan results are received, so cancel the scheduled scan to allow immediate scan and connection attempt.

* P2P: Fix P2P_CONNECT-auto fallback to GO Neg with group interfaceJouni Malinen2015-02-081-6/+23
| | | | | | | | | | | | | | | | | | | If a separate P2P group interface was used, P2P_CONNECT-auto fallback to GO Negotiation could result in use of freed memory and segmentation fault. This happened in cases where the peer GO was found in some old scans, but not in the first scan triggered by the P2P_CONNECT-auto command ("P2P: Peer was found running GO in older scan -> try to join the group" shows up in the debug log). In addition, the GO would still need to reply to PD Request to allow this code path to be triggered. When five scans for the GO were completed in this sequence, the P2P group interface was removed as part of falling back to GO Negotiation. However, that ended up dereferencing the freed wpa_s instance at the end of scan event processing. Fix this by reordering code a bit and breaking out from EVENT_SCAN_RESULTS processing if the interface could have been removed. Signed-off-by: Jouni Malinen <j@w1.fi>
* Simplify eapol_sm_notify_pmkid_attempt()Jouni Malinen2015-01-281-1/+1
| | | | | | | | Drop the unneeded 'attempt' argument. This was originally used for indicating an aborted PMKID caching attempt, but a fix in 2006 removed the only such user and since that time, only attempt == 1 has been used. Signed-off-by: Jouni Malinen <j@w1.fi>
* Ignore pmf=1 default if driver does not support PMFJouni Malinen2015-01-271-2/+1
| | | | | | | | | | | Connection with a PMF enabled AP will fail if we try to negotiate PMF while the local driver does not support this. Since pmf=1 does not require PMF for a successful connection, it can be ignored in such a case to avoid connectivity issues with invalid configuration. This makes it somewhat easier to allow upper layer programs to use pmf=1 default regardless of driver capabilities. Signed-off-by: Jouni Malinen <j@w1.fi>
* Preparations for variable length KCK and KEKJouni Malinen2015-01-261-2/+4
| | | | | | | | This modifies struct wpa_ptk to allow the length of KCK and KEK to be stored. This is needed to allow longer keys to be used, e.g., with Suite B 192-bit level. Signed-off-by: Jouni Malinen <j@w1.fi>
* Move external_scan_running to wpa_radioBen Rosenfeld2015-01-191-5/+5

* Add address masks to BSSID listsStefan Tomanek2015-01-101-2/+15
| | | | | | | | | | | | In many applications it is useful not just to enumerate a group of well known access points, but to use a address/mask notation to match an entire set of addresses (ca:ff:ee:00:00:00/ff:ff:ff:00:00:00). This change expands the data structures used by MAC lists to include a mask indicating the significant (non-masked) portions of an address and extends the list parser to recognize mask suffixes.

* Add network specific BSSID black and white listsStefan Tomanek2015-01-101-0/+32
| | | | | | | | | | | | This change adds the configuration options "bssid_whitelist" and "bssid_blacklist" used to limit the AP selection of a network to a specified (finite) set or discard certain APs. This can be useful for environments where multiple networks operate using the same SSID and roaming between those is not desired. It is also useful to ignore a faulty or otherwise unwanted AP.

* Handle interface disabled/enabled more consistentlyJouni Malinen2015-01-081-0/+10
| | | | | | | | | | | | | It was possible for the interface not to be marked in INTERFACE_DISABLED state in case the event was processed for P2P GO because the wpa_s instance could have been removed in case of a separate group interface. Change the state first to avoid leaving different state for the case where separate group interface is not used. Mark scan to be a normal scan on INTERFACE_ENABLED so that scanning rules (e.g., skip scan if no networks enabled) get used consistently. Signed-off-by: Jouni Malinen <j@w1.fi>
* P2P: Indicate reason=UNAVAILABLE for group netdev going downJouni Malinen2015-01-081-1/+5
| | | | | | | | | | There is a race condition between receiving an AP stopped event and netdev down event. These resulted in different group removal reasons on a GO device (UNAVAILABLE for stop AP event coming first and REQUESTED for netdev event first). Make this more consistent by reporting UNAVAILABLE for both possible cases. Signed-off-by: Jouni Malinen <j@w1.fi>
* WMM AC: Reconfigure tspecs on reassociation to the same BSSEliad Peller2015-01-041-0/+3
| | | | | | | | | | | The specification requires the tspecs to be kept upon reassociation to the same BSS. Save the last tspecs before such reassociation, and reconfigure on the association notification. Note that the current flow is not transparent to the user (it is notified about deauth/reassoc and tspec removal/addition). Signed-off-by: Eliad Peller <eliadx.peller@intel.com>
* WMM AC: Delete tspecs on roamingEliad Peller2015-01-041-2/+0
| | | | | | | | | | In case of roaming, we don't get disassoc notification, but still want to remove the existing tspecs. Move the wmm_ac_notify_disassoc() call to the state change function, which get called also on roaming. Signed-off-by: Eliad Peller <eliadx.peller@intel.com>
* SAE: Clear keys from memory on disassociationJouni Malinen2014-12-291-9/+1
| | | | | | | | There is no need to keep temporary keys in memory beyond the end of the association, so explicitly clear any SAE buffers that can contain keys as soon as such keys are not needed. Signed-off-by: Jouni Malinen <j@w1.fi>
* Ignore auth/assoc timeout events in mesh configurationJouni Malinen2014-11-301-0/+14
| | | | | | | | | | | | | It was possible for auth/assoc timeout/failure event from the driver to result in unexpected processing during mesh group setup if that operation was started before the previously started driver operation to association/connect had completed. Since those events cannot happen in mesh cases, ignore them to avoid issues due to this corner case. For example, monitor_iface_unknown_sta followed by wpas_mesh_secure test case resulted in failure without this change. Signed-off-by: Jouni Malinen <j@w1.fi>

* SME: Add RRM support to association requestAssaf Krauss2014-11-221-0/+2
| | | | | | | | | | | In case the AP we are associating with advertises support for RRM, advertise our own RRM support in the (Re)Association Request frame. This is done by adding an RRM Capabilities IE. The underlying driver is expected to further add a Power Capabilities IE to the request, and set the Radio Measurement flag in the Capability Info field. At this point the RRM Capabilities IE advertises no measurement support. Signed-off-by: Assaf Krauss <assaf.krauss@intel.com>
