* NFC: pn544: i2c: Add firmware download implementation for pn544Eric Lapuyade2013-08-14
| | | | | | | | | | The pn544 can enter a firmware update mode where firmware blobs can be pushed through the i2c line and flashed on the target. A special command allows to verify that blobs are correctly flashed and this is what we do for every downloaded firmware blob.

* NFC: pn544: Add firmware operations hci opsEric Lapuyade2013-08-14
| | | | | | | | | The firmware operation callback is passed by the physical layer to the hci driver during probe. All the driver does is to store it and call it when the fw_upload hci ops is invoked.

* NFC: pn544: i2c: Add firmware download mode power-on supportEric Lapuyade2013-08-14
| | | | | | | | This is in preparation for pn544-i2c firmware download feature, where we need to know if we're in regular or firmware upload mode. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: pn533: Add some polling entropySamuel Ortiz2013-08-14
| | | | | | | | | | By not always starting the polling loop from the same modulation, we avoid entering infinite loops where devices exporting 2 targets (on 2 different modulations) get the same target activated over and over. If this target is not readable (e.g. a wallet emulating a tag), we will stay in an error loop for ever. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: pn533: Add delay between each poll frameSamuel Ortiz2013-08-14
| | | | | | | | It seems that some pn533 firmwares go belly up when being asked to send poll frames too frequently. Adding a 10ms delay between each of them calm the chip down and prevent it from crashing. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: pn533: Store the correct frame size (normal vs ext)Olivier Guiter2013-08-14
| | | | | | | | | | | | The extended information frame are sent by PN533 to exchange frames larger than 255 bytes. These extended frame are very close from the standard ones except for the header size length. On each incoming frame, we set the correct header length, and we do that only for the standard pn533 chipsets as the acr122 does not seem to support extended frames properly.

* NFC: pn533: Split large Tx frames in chunksOlivier Guiter2013-08-14
| | | | | | | | On sending large frames (size > 262), we split it in multiple chunks and send them asynchronously with MI bit. Signed-off-by: Olivier Guiter <olivier.guiter@linux.intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: pn533: Add extended information frame decoding supportOlivier Guiter2013-08-14
| | | | | | | | | | | Extended Information frames are slightly different from standard frames as they can (theorically) handle datas up tu 64kB. PN533 firmware only supports packet data up to 265 (incl. TFI byte) This kind of frame are used when the pn533 wants to exchange more than 255 bytes, and this patch handles the reception of such frames.

* NFC: pn533: Enable AUTO RFCASamuel Ortiz2013-08-14
| | | | | | | | | The AUTO RFCA bit forbids the pn533 chipset to turn its radio on whenever an external field is present. Without this bit set, some devices seems to get over flood by the pn533 rf field and thus become hardly detectable. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: pn533: Unconditionaly select the highest p2p bit rateSamuel Ortiz2013-08-14
| | | | | | | p2p devices must be able to support 424 kbps, so we should always select that bitrate in initiator mode. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: pn533: Request System code from SENSF_REQSamuel Ortiz2013-08-14
| | | | | | | Some devices are getting confused when not being asked for their system code with type F. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: pn533: Fix the pn533 polling loopSamuel Ortiz2013-08-14
| | | | | | | | | By turning the radio off after each failed polling try, we dramatically improve the pn533 polling loop efficiency. Without this fix, all Android phones running the broadcom NFC stack are almost never detected. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: pn533: Fix hardware busy loop when establishing the LLCP linkSamuel Ortiz2013-08-14
| | | | | | | | | By using the standard setting for the regular pn533 dongles, we no longer wait for ever for an ATR_RES. Without this, a failing ATR_REQ will put the hardware into a busy loop, constantly waiting for an ATR_RES. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...

| * NFC: Add a nfc hardware simulation driverThierry Escande2013-06-14
| | | | | | | | | | | | | | | | | | | | | | | | This driver declares two virtual NFC devices supporting NFC-DEP protocol. An LLCP connection can be established between them and all packets sent from one device is sent back to the other, acting as loopback devices. Once established, the LLCP link can be disconnected by disabling the target device (with rfkill, nfctool, or neard disable-adapter test script).

| * NFC: Remove the static supported_se fieldSamuel Ortiz2013-06-14
| | | | | | | | | | | | | | | | | | | | | | | | Supported secure elements are typically found during a discovery process initiated when the NFC controller is up and running. For a given NFC chipset there can be many configurations (embedded SE or not, with or without a SIM card wired to the NFC controller SWP interface, etc...) and thus driver code will never know before hand which SEs are available. So we remove this field, it will be replaced by a real SE discovery mechanism. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFCID2 is defined as the first 2 manufacturer ID (IDm) bytes. NFC DEP (NFC peer to peer) devices Type-F NFCID2 must start with 0x01fe according to the NFC Digital Specification. By checking those first 2 bytes we send the right command either to the reader gate when NFCID2 != 0x1fe (The NFC tag case) or to the NFCIP1 gate when seeing an NFC DEP device (The NFC peer to peer case). Without this fix, Felica (Type F) tags are not properly detected with this driver. Signed-off-by: Arron Wang <arron.wang@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | ACS ACR122U is an USB NFC reader, PC/SC and CCID compilant, based on NXP PN532 chip. Internally, it's build of MCU, PN532 and an antenna. MCU makes the device CCID and PC/SC compilant and provide USB connection. In this achitecture, a host cannot talk directly to PN532 and must rely on MCU. Luckily, MCU exposes pseud-APDU through PC/SC Escape mechanism which let the host to transmit standard PN532 commands directly to PN532 chip with some limitations. The frame roughly looks like: CCID header | APDU header | PN532 header (pc_to_rdr_escape) | (pseudo apdu Direct Tramsmit) | (len, TFI, cmd, params) Accordign to limitations, ACR122U does't provide any mechanism to abort last issued command.

| | | | | | | | | | | | | | | | In all cases (send_cmd_async, send_data_async and send_sync) pn533_send_async_complete() handles all responses internally, so there is no need to pass this as a callback. Cmd context is passed to __pn533_send_frame_async in all the cases as well. It's already kept in struct pn533 which is available all the time the device is attached. So we can make use of it instead.
