2012-10-26NFC: Initial SNL supportSamuel Ortiz
SNL (Service Name Lookup) allows for LLCP peers to map service names with SAPs. This is mandatory for connection less support as peers need to get the right SAPs without sending the CONNECT frame. Here we only support the Rx part of SNL. The Tx one will be implemented when supporting connection less LLCP sockets. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-10-26NFC: Add SNL frame building routineSamuel Ortiz
SNL (Service Name Lookup) frames are used to respond to SNL requests. This is needed for SDP implementation. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-10-26NFC: Use llcp_allocate_pdu to build the DISC framesSamuel Ortiz
We no longer need to be atomic as this is only called from llcp_sock_release(). Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-10-26NFC: Avoid falling back to SYMM when sk is NULLSamuel Ortiz
In some cases (SNL, DISC, DM) we need to send an LLCP skbs without having a sock owning it. I frames are an exception here since they may be requeued to the llcp_sock queue. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-10-26NFC: HCI check presence must not fail when driver doesn't support itEric Lapuyade
When the driver does not support checking the tag is still present, it must return -EOPNOTSUPP. The NFC Core will then stop asking and not report a tag lost event to user space. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2012-10-19mac80211: make client powersave independent of interface typeMarco Porsch
This patch prepares mac80211 for a later implementation of mesh or ad-hoc powersave clients. The structures related to powersave (buffer, TIM map, counters) are moved from the AP-specific interface structure to a generic structure that can be embedded into any interface type. The functions related to powersave are prepared to allow easy extension with different interface types. For example with: + } else if (sta->sdata->vif.type == NL80211_IFTYPE_MESH_POINT) { + ps = &sdata->u.mesh.ps; Some references to the AP's beacon structure are removed where they were obviously not used. The patch compiles without warning and has been briefly tested as AP interface with one client in PS mode.

2012-10-18nl/cfg80211: force scan using an AP vif if requestedAntonio Quartulli
If the user wants to scan using a vif configured as AP, cfg80211 must give him a chance to do it, even if this will disrupt the stations performance due to off-channel scanning. To do so, this patch adds a 'force' flag to the SCAN_TRIGGER command which tells cfg80211 to perform the scanning operation even if the vif is an AP and the beaconing has already started.

2012-10-18mac80211: Notify new IBSS network creationSujith Manoharan
Initialization of beacon transmission in IBSS mode depends on whether a new BSS is being created or joined. When joining an existing IBSS network, beaconing has to start only after a TSF-sync has happened - this is explained in 11.1.4. Introduce a new parameter in the BSS information structure to indicate creator/joiner mode.

2012-10-18mac80211: add support for tx to abort low priority scan requestsSam Leffler
Use NL80211_SCAN_FLAG_LOW_PRIORITY flag in mac80211's scan state machine to prematurely terminate scan operations if outbound traffic collides.

2012-10-18cfg80211: add support for flushing old scan resultsSam Leffler
Add an NL80211_SCAN_FLAG_FLUSH flag that causes old bss cache entries to be flushed on scan completion. This is useful for collecting guaranteed fresh scan/survey result (e.g. on resume). For normal scan, flushing only happens on successful completion of a scan; i.e. it does not happen if the scan is aborted. For scheduled scan, previous scan results are flushed everytime when we get new scan results. This feature is enabled by default. Drivers can disable it by unsetting the NL80211_FEATURE_SCAN_FLUSH flag.

2012-10-18wireless: use OR operation to set wiphy featuresJohannes Berg
The next patch will introduce a flag that is set by default in cfg80211 so drivers and mac80211 need to use |= to set features they have so that they don't clear the already-set feature. We could set the flag in wiphy_register() instead of wiphy_new() to avoid this patch, but then the drivers couldn't *unset* flags they don't want to use even though the implementation is generic.

2012-10-18cfg80211: add scan flag to indicate its prioritySam Leffler

2012-10-17mac80211: connect with HT20 if HT40 is not permittedJohannes Berg
Some changes to fix issues with HT40 APs in Korea and follow-up changes to allow using HT40 even if the local regulatory database disallows it caused issues with iwlwifi (and could cause issues with other devices); iwlwifi firmware would assert if you tried to connect to an AP that has an invalid configuration (e.g. using HT40- on channel 140.) Fix this, while avoiding the "Korean AP" issue by disabling HT40 and advertising HT20 to the AP when connecting.

2012-10-17mac80211: Allow station mode SAE to be implemented in user spaceJouni Malinen
SAE uses two rounds of Authentication frames and both rounds require considerable calculation to be done.
