2013-09-26mac80211: add ieee80211_iterate_active_interfaces_rtnl()Johannes Berg
If it is needed to disconnect multiple virtual interfaces after (WoWLAN-) suspend, the most obvious approach would be to iterate all interfaces by calling ieee80211_iterate_active_interfaces() and then call ieee80211_resume_disconnect() for each one. This is what the iwlmvm driver does. Unfortunately, this causes a locking dependency from mac80211's iflist_mtx to the key_mtx. This is problematic as the former is intentionally never held while calling any driver operation to allow drivers to iterate with their own locks held. The key_mtx is held while installing a key into the driver though, so this new lock dependency means drivers implementing the logic above can no longer hold their own lock while iterating. To fix this, add a new ieee80211_iterate_active_interfaces_rtnl() function that iterates while the RTNL is already held. This is true during suspend/resume, so that then the locking dependency isn't introduced. While at it, also refactor the various interface iterators and keep only a single implementation called by the various cases. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-09-25Bluetooth: Add new mgmt_set_advertising commandJohan Hedberg
This patch adds a new mgmt command for enabling and disabling LE advertising. The command depends on the LE setting being enabled first and will return a "rejected" response otherwise. The patch also adds safeguards so that there will ever only be one set_le or set_advertising command pending per adapter. The response handling and new_settings event sending is done in an asynchronous request callback, meaning raw HCI access from user space to enable advertising (e.g. hciconfig leadv) will not trigger the new_settings event. This is intentional since trying to support mixed raw HCI and mgmt access would mean adding extra state tracking or new helper functions, essentially negating the benefit of using the asynchronous request framework. The HCI_LE_ENABLED and HCI_LE_PERIPHERAL flags however are updated correctly even with raw HCI access so this will not completely break subsequent access over mgmt.

2013-09-25Bluetooth: Add new mgmt setting for LE advertisingJohan Hedberg
This patch adds a new mgmt setting for LE advertising and hooks up the necessary places in the mgmt code to operate on the HCI_LE_PERIPHERAL flag (which corresponds to this setting). This patch does not yet add any new command for enabling the setting - that is left for a subsequent patch.

2013-09-25Bluetooth: Use async request for LE enable/disableJohan Hedberg
This patch updates the code to use an asynchronous request for handling the enabling and disabling of LE support. This refactoring is necessary as a preparation for adding advertising support, since when LE is disabled we should also disable advertising, and the cleanest way to do this is to perform the two respective HCI commands in the same asynchronous request.

2013-09-25NFC: NCI: Modify NCI SPI to implement CS/INT handshake per the specEric Lapuyade
The NFC Forum NCI specification defines both a hardware and software protocol when using a SPI physical transport to connect an NFC NCI Chipset. The hardware requirement is that, after having raised the chip select line, the SPI driver must wait for an INT line from the NFC chipset to raise before it sends the data. The chip select must be raised first though, because this is the signal that the NFC chipset will detect to wake up and then raise its INT line. If the INT line doesn't raise in a timely fashion, the SPI driver should abort operation. When data is transferred from Device host (DH) to NFC Controller (NFCC), the signaling sequence is the following: Data Transfer from DH to NFCC • 1-Master asserts SPI_CSN • 2-Slave asserts SPI_INT • 3-Master sends NCI-over-SPI protocol header and payload data • 4-Slave deasserts SPI_INT • 5-Master deasserts SPI_CSN When data must be transferred from NFCC to DH, things are a little bit different. Data Transfer from NFCC to DH • 1-Slave asserts SPI_INT -> NFC chipset irq handler called -> process reading from SPI • 2-Master asserts SPI_CSN • 3-Master send 2-octet NCI-over-SPI protocol header • 4-Slave sends 2-octet NCI-over-SPI protocol payload length • 5-Slave sends NCI-over-SPI protocol payload • 6-Master deasserts SPI_CSN In this case, SPI driver should function normally as it does today. Note that the INT line can and will be lowered anytime between beginning of step 3 and end of step 5. A low INT is therefore valid after chip select has been raised. This would be easily implemented in a single driver. Unfortunately, we don't write the SPI driver and I had to imagine some workaround trick to get the SPI and NFC drivers to work in a synchronized fashion. The trick is the following: - send an empty spi message: this will raise the chip select line, and send nothing. We expect the /CS line will stay arisen because we asked for it in the spi_transfer cs_change field - wait for a completion, that will be completed by the NFC driver IRQ handler when it knows we are in the process of sending data (NFC spec says that we use SPI in a half duplex mode, so we are either sending or receiving). - when completed, proceed with the normal data send. This has been tested and verified to work very consistently on a Nexus 10 (spi-s3c64xx driver). It may not work the same with other spi drivers. The previously defined nci_spi_ops{} whose intended purpose were to address this problem are not used anymore and therefore totally removed. The nci_spi_send() takes a new optional write_handshake_completion completion pointer. If non NULL, the nci spi layer will run the above trick when sending data to the NFC Chip. If NULL, the data is sent normally all at once and it is then the NFC driver responsibility to know what it's doing.

2013-09-25NFC: NCI: nci_spi_recv_frame() now returns (not forward) the read frameEric Lapuyade
Previously, nci_spi_recv_frame() would directly transmit incoming frames to the NCI Core. However, it turns out that some NFC NCI Chips will add additional proprietary headers that must be handled/removed before NCI Core gets a chance to handle the frame. With this modification, the chip phy or driver are now responsible to transmit incoming frames to NCI Core after proper treatment, and NCI SPI becomes a driver helper instead of sitting between the NFC driver and NCI Core. As a general rule in NFC, *_recv_frame() APIs are used to deliver an incoming frame to an upper layer. To better suit the actual purpose of nci_spi_recv_frame(), and go along with its nci_spi_send() counterpart, the function is renamed to nci_spi_read() The skb is returned as the function result Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-09-25NFC: Define secure element IO API and commandsSamuel Ortiz
In order to send and receive ISO7816 APDUs to and from NFC embedded secure elements, we define a specific netlink command. On a typical SE use case, host applications will send very few APDUs (Less than 10) per transaction. This is why we decided to go for a simple netlink API. Defining another NFC socket protocol for such low traffic would have been overengineered. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-09-25NFC Digital: Add NFC-A technology supportThierry Escande
This adds support for NFC-A technology at 106 kbits/s. The stack can detect tags of type 1 and 2. There is no support for collision detection. Tags can be read and written by using a user space application or a daemon like neard. The flow of polling operations for NFC-A detection is as follow: 1 - The digital stack sends the SENS_REQ command to the NFC device. 2 - The NFC device receives a SENS_RES response from a peer device and passes it to the digital stack. 3 - If the SENS_RES response identifies a type 1 tag, detection ends. NFC core is notified through nfc_targets_found(). 4 - Otherwise, the digital stack sets the cascade level of NFCID1 to CL1 and sends the SDD_REQ command. 5 - The digital stack selects SEL_CMD and SEL_PAR according to the cascade level and sends the SDD_REQ command. 4 - The digital stack receives a SDD_RES response for the cascade level passed in the SDD_REQ command. 5 - The digital stack analyses (part of) NFCID1 and verify BCC. 6 - The digital stack sends the SEL_REQ command with the NFCID1 received in the SDD_RES. 6 - The peer device replies with a SEL_RES response 7 - Detection ends if NFCID1 is complete. NFC core notified of new target by nfc_targets_found(). 8 - If NFCID1 is not complete, the cascade level is incremented (up to and including CL3) and the execution continues at step 5 to get the remaining bytes of NFCID1. Once target detection is done, type 1 and 2 tag commands must be handled by a user space application (i.e neard) through the NFC core. Responses for type 1 tag are returned directly to user space via NFC core. Responses of type 2 commands are handled differently. The digital stack doesn't analyse the type of commands sent through im_transceive() and must differentiate valid responses from error ones. The response process flow is as follow: 1 - If the response length is 16 bytes, it is a valid response of a READ command. the packet is returned to the NFC core through the callback passed to im_transceive(). Processing stops. 2 - If the response is 1 byte long and is a ACK byte (0x0A), it is a valid response of a WRITE command for example. First packet byte is set to 0 for no-error and passed back to the NFC core. Processing stops. 3 - Any other response is treated as an error and -EIO error code is returned to the NFC core through the response callback. Moreover, since the driver can't differentiate success response from a NACK response, the digital stack has to handle CRC calculation. Thus, this patch also adds support for CRC calculation. If the driver doesn't handle it, the digital stack will calculate CRC and will add it to sent frames. CRC will also be checked and removed from received frames. Pointers to the correct CRC calculation functions are stored in the digital stack device structure when a target is detected. This avoids the need to check the current target type for every call to im_transceive() and for every response received from a peer device.

2013-09-25NFC Digital: Implement driver commands mechanismThierry Escande
This implements the mechanism used to send commands to the driver in initiator mode through in_send_cmd(). Commands are serialized and sent to the driver by using a work item on the system workqueue. Responses are handled asynchronously by another work item. Once the digital stack receives the response through the command_complete callback, the next command is sent to the driver. This also implements the polling mechanism. It's handled by a work item cycling on all supported protocols. The start poll command for a given protocol is sent to the driver using the mechanism described above. The process continues until a peer is discovered or stop_poll is called. This patch implements the poll function for NFC-A that sends a SENS_REQ command and waits for the SENS_RES response.

2013-09-25NFC: Digital Protocol stack implementationThierry Escande
This is the initial commit of the NFC Digital Protocol stack implementation. It offers an interface for devices that don't have an embedded NFC Digital protocol stack. The driver instantiates the digital stack by calling nfc_digital_allocate_device(). Within the nfc_digital_ops structure, the driver specifies a set of function pointers for driver operations. These functions must be implemented by the driver and are: in_configure_hw: Hardware configuration for RF technology and communication framing in initiator mode. This is a synchronous function. in_send_cmd: Initiator mode data exchange using RF technology and framing previously set with in_configure_hw. The peer response is returned through callback cb. If an io error occurs or the peer didn't reply within the specified timeout (ms), the error code is passed back through the resp pointer. This is an asynchronous function. tg_configure_hw: Hardware configuration for RF technology and communication framing in target mode. This is a synchronous function. tg_send_cmd: Target mode data exchange using RF technology and framing previously set with tg_configure_hw. The peer next command is returned through callback cb. If an io error occurs or the peer didn't reply within the specified timeout (ms), the error code is passed back through the resp pointer. This is an asynchronous function. tg_listen: Put the device in listen mode waiting for data from the peer device. This is an asynchronous function. tg_listen_mdaa: If supported, put the device in automatic listen mode with mode detection and automatic anti-collision. In this mode, the device automatically detects the RF technology and executes the anti-collision detection using the command responses specified in mdaa_params. The mdaa_params structure contains SENS_RES, NFCID1, and SEL_RES for 106A RF tech. NFCID2 and system code (sc) for 212F and 424F. The driver returns the NFC-DEP ATR_REQ command through cb. The digital stack deducts the RF tech by analyzing the SoD of the frame containing the ATR_REQ command. This is an asynchronous function. switch_rf: Turns device radio on or off. The stack does not call explicitly switch_rf to turn the radio on. A call to in|tg_configure_hw must turn the device radio on. abort_cmd: Discard the last sent command. Then the driver registers itself against the digital stack by using nfc_digital_register_device() which in turn registers the digital stack against the NFC core layer. The digital stack implements common NFC operations like dev_up(), dev_down(), start_poll(), stop_poll(), etc. This patch is only a skeleton and NFC operations are just stubs.

2013-09-25NFC: NCI: Simplify NCI SPI to become a simple framing/checking layerEric Lapuyade
NCI SPI layer should not manage the nci dev, this is the job of the nci chipset driver. This layer should be limited to frame/deframe nci packets, and optionnaly check integrity (crc) and manage the ack/nak protocol. The NCI SPI must not be mixed up with an NCI dev. spi_[dev|device] are therefore renamed to a simple spi for more clarity. The header and crc sizes are moved to nci.h so that drivers can use them to reserve space in outgoing skbs. nci_spi_send() is exported to be accessible by drivers.

2013-09-24tcp: syncookies: reduce cookie lifetime to 128 secondsFlorian Westphal
We currently accept cookies that were created less than 4 minutes ago (ie, cookies with counter delta 0-3). Combined with the 8 mss table values, this yields 32 possible values (out of 2**32) that will be valid. Reducing the lifetime to < 2 minutes halves the guessing chance while still providing a large enough period. While at it, get rid of jiffies value -- they overflow too quickly on 32 bit platforms. getnstimeofday is used to create a counter that increments every 64s. perf shows getnstimeofday cost is negible compared to sha_transform; normal tcp initial sequence number generation uses getnstimeofday, too.
