{nl,cfg}80211: make peer link expiration time configurable 2013-06-11T12:16:29+00:00 Colleen Twitty colleen@cozybit.com 2013-06-03T16:53:39+00:00 8e7c053853b7d299e8a2b8733659b0df8eee51f7 If a STA has a peer that it hasn't seen any tx activity from for a certain length of time, the peer link is expired. This means the inactive STA is removed from the list of peers and that STA is not considered a peer again unless it re-peers. Previously, this inactivity time was always 30 minutes. Now, add it to the mesh configuration and allow it to be configured. Retain 30 minutes as a default value.

cfg80211: Allow TDLS peer AID to be configured for VHT 2013-05-24T20:36:28+00:00 Jouni Malinen jouni@qca.qualcomm.com 2013-05-16T17:11:08+00:00 5e4b6f5698421d94226cc2f80eae6d613c9acef8 VHT uses peer AID in the PARTIAL_AID field in TDLS frames. The current design for TDLS is to first add a dummy STA entry before completing TDLS Setup and then update information on this STA entry based on what was received from the peer during the setup exchange. In theory, this could use NL80211_ATTR_STA_AID to set the peer AID just like this is used in AP mode to set the AID of an association station. However, existing cfg80211 validation rules prevent this attribute from being used with set_station operation. To avoid interoperability issues between different kernel and user space version combinations, introduce a new nl80211 attribute for the purpose of setting TDLS peer AID. This attribute can be used in both the new_station and set_station operations. It is not supposed to be allowed to change the AID value during the lifetime of the STA entry, but that validation is left for drivers to do in the change_station callback.

cfg80211: introduce critical protocol indication from user-space 2013-04-22T13:48:00+00:00 Arend van Spriel arend@broadcom.com 2013-04-18T13:49:00+00:00 5de17984898c5758fc6ebe08eccea9f4b6548914 Some protocols need a more reliable connection to complete successful in reasonable time. This patch adds a user-space API to indicate the wireless driver that a critical protocol is about to commence and when it is done, using nl80211 primitives NL80211_CMD_CRIT_PROTOCOL_START and NL80211_CRIT_PROTOCOL_STOP. There can be only on critical protocol session started per registered cfg80211 device. The driver can support this by implementing the cfg80211 callbacks .crit_proto_start() and .crit_proto_stop(). Examples of protocols that can benefit from this are DHCP, EAPOL, APIPA. Exactly how the link can/should be made more reliable is up to the driver. Things to consider are avoid scanning, no multi-channel operations, and alter coexistence schemes.
