2012-10-29carl9170: fix spurious transmissions in sniffer modeChristian Lamparter
Several people have complained about an unusual and undocumented feature of the AR9170 hardware: In siffer mode, the hardware generates spurious ACK frames for every received frame... even broadcasts. The reason for this malfunction is unknown: <http://marc.info/?l=linux-wireless&m=134517238506033> But there's a workaround: Instead of the special sniffer mode, the hardware will be put into station mode and all rx filters are disabled.

2012-10-29Merge tag 'nfc-next-3.8-1' of ↵John W. Linville
git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-3.0 This is the first NFC pull request for 3.8 With this one we have: - pn544 p2p support. - pn544 physical and HCI layers separation. We are getting the pn544 driver ready to support non i2c physical layers. - LLCP SNL (Service Name Lookup). This is the NFC p2p service discovery protocol. - LLCP datagram sockets (connection less) support. - IDR library usage for NFC devices indexes assignement. - NFC netlink extension for setting and getting LLCP link characteristics. - Various code style fixes and cleanups spread over the pn533, LLCP, HCI and pn544 code.

2012-10-29NFC: Extend netlink interface for LTO, RW, and MIUX parameters supportThierry Escande
NFC_CMD_LLC_GET_PARAMS: request LTO, RW, and MIUX parameters for a device NFC_CMD_LLC_SET_PARAMS: set one or more of LTO, RW, and MIUX parameters for a device. LTO must be set before the link is up otherwise -EINPROGRESS is returned. RW and MIUX can be set at anytime and will be passed in subsequent CONNECT and CC messages. If one of the passed parameters is wrong none is set and -EINVAL is returned. Signed-off-by: Thierry Escande <thierry.escande@linux.intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-10-26NFC: Purge LLCP socket Tx queues when being disconnectedSamuel Ortiz

2012-10-26NFC: Return NULL when no LLCP socket for a dsap,ssap couple is foundSamuel Ortiz

2012-10-26NFC: Implement LLCP connection less Tx pathSamuel Ortiz
It simply involves getting the client dsap and ssap and calling the UI frame building and sending routine. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-10-26NFC: UI frame sending routine implementationSamuel Ortiz
UI frames still need to follow the MIU rule, and they need to use the client passed dsap as the listening socket dsap is stuck on SDP. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-10-26NFC: Forward LLCP datagrams to userspaceSamuel Ortiz

2012-10-26NFC: Keep connection less bound sockets alive when DEP link goes downSamuel Ortiz
When DEP goes down, bound cl sockets can be kept alive as there is no reason to kill a connection less server socket because the LLCP link went down. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

Connection less server sockets will be in BOUND state, not LISTEN. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-10-26NFC: Reserve LLCP ssap when replying to an SNL frameSamuel Ortiz
Replying to an SNL (Service Name Lookup) means that the other end of the link can now rely on our answer (Which is an ssap) and thus we have to reserve it. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

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: 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: Separate pn544 hci driver in HW dependant and independant partsEric Lapuyade

2012-10-26NFC: HCI check presence must not fail when driver doesn't support itEric Lapuyade
