* P2P: Add 802.11ax support for P2P GOPeng Xu2019-01-121-3/+3
| | | | | | | | An optional parameter "he" is added to p2p_connect, p2p_group_add, and p2p_invite to enable 11ax HE support. The new p2p_go_he=1 configuration parameter can be used to request this to be enabled by default. Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
* P2P: Add optional op_class argument to P2P_SET listen_channelLior David2016-03-071-1/+6
| | | | | | | | | | | The existing implementation in p2p_ctrl_set used a hard-coded operating class 81 which is only suitable for the social channels in the 2.4 GHz band, and will not work for the social channel in the 60 GHz band. Extend this by adding an optional op_class argument to P2P_SET listen_channel. If not specified, use the default value of 81 to match existing behavior.

* P2P: Add an option to specify group SSID in P2P_CONNECT join caseJouni Malinen2015-12-301-0/+7
| | | | | | | | | | | The new optional ssid=<hexdump> argument to P2P_CONNECT can be used to make P2P Client operations during join-an-existing-group more robust by filtering out scan results based on the SSID in addition to the P2P Device/Interface Address. This can help if the same MAC address has been used in multiple groups recently and the cached scan results may still include an older BSS. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
* P2P: Allow a specific channel to be specified in P2P_FINDDaisuke Niwa2015-02-281-2/+4
| | | | | | | | | The optional freq=<MHz> can now be used with the P2P_FIND command to specify a single channel to scan during the first round of P2P search. For example, this can be used to replace the full initial scan with a single channel scan of a known operation channel. Signed-off-by: Daichi Ueura <daichi.ueura@sonymobile.com>

* P2P: Make the default p2p_find delay value configurableNirav Shah2014-06-091-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the p2p_find default delay value configurable as p2p_search_delay parameter through the configuration file (and through control interface "SET p2p_search_delay <value>" on the P2P management interface. This parameter controls the number milliseconds of extra delay that is added between search iterations when there is a concurrent operation in progress. This can be used, e.g., p2p_search_delay=100 to make p2p_find friendlier to concurrent operations by avoiding it from taking 100% of the radio resources. The default value is the previous default, i.e., 500 ms. Smaller values can be used to find peers more quickly at the cost of larger effect to concurrent operations while a larger value leaves more time for the concurrent operations at the cost of making device discovery take longer time. The optional p2p_find delay argument can still be used to override the search delay for each search operation. Since the P2P_CONCURRENT_SEARCH_DELAY macro is not used anymore, the driver specific build parameter for bcmdhd from Android.mk is also removed. Similar configuration can now be achieved with p2p_search_delay=0 in the p2p0 interface configuration file. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
* P2P: Address few issues seen with P2P SDJithu Jance2014-02-201-3/+2
| | | | | | | | | | | | | | | | | | Suppose we have multiple peers and we have peers advertising SD capability, but no services registered for advertising. In this case, even if there are multiple broadcast queries set, we might end up sending only the lastly added broadcast query to the same device (since SD_INFO won't get set for the first broadcast query). Add support for multiple wildcard queries to be tracked to enable this type of use case. Some times it is seen that before advancing to next device in the list, the scan results come and update SD_SCHEDULE flag. This will result in sending the already sent query to the same device without giving chance to other devices. This issue again is seen with peer devices advertising SD capability without any services registered. Signed-off-by: Jithu Jance <jithu@broadcom.com>
* P2P: Allow requested device type to be specified with p2p_findJouni Malinen2014-01-081-1/+6

* P2P: Send received Presence Response information to ctrl_iface monitorsJouni Malinen2014-01-011-2/+4
| | | | | | | | | The P2P_PRESENCE_REQ command did not give any easily available indication of the response received from the GO. Make this more useful by providing such response (if received) as a ctrl_iface monitor event (P2P-PRESENCE-RESPONSE). Signed-hostap: Jouni Malinen <j@w1.fi>
* P2P: Add VHT parameter to P2P operationsEliad Peller2013-10-271-3/+5
| | | | | | | | | | | | Add the option to ask for VHT operation similarly to the way ht40 is configured - either by adding 'vht' param to the relevant p2p_* commands or by configuring p2p_go_vht=1 in the configuration file. This patch only adds the configuration option (e.g., via control interface). The actual handling of the VHT parameter (asking the driver to use VHT, etc.) will be done by the following patch.

| | | | | | | | | | When re-invoking a persistent group in P2P client role, the new pref=<MHz> parameter can now be used with the p2p_invite command to indicate a preferred operating frequency. Unlike the older freq=<MHz> parameter, this leaves GO an option to select another channel (from our supported channels) if the GO cannot accept the channel.

* P2P: Add option for Provision Discovery before GO NegotiationJouni Malinen2012-05-111-1/+6
| | | | | | | | | | This is a workaround for interoperability issues with some deployed P2P implementations that require a Provision Discovery exchange to be used before GO Negotiation. The new provdisc parameter for the p2p_connect command can be used to request this behavior without having to run a separate p2p_prov_disc command.

* P2P: Add option to force SSID/passphrase for GO NegotiationJouni Malinen2012-04-271-2/+8
| | | | | | | | | | | | | 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>
