* NFC: nci: Add firmware download supportClément Perrochaud2015-03-261-0/+11
| | | | | | | | | | | | | A simple forward for firmware download (i.e. sending a new firmware to the NFC adapter) from the NFC subsystem to the drivers. This feature is required to update the firmware of NXP-NCI NFC controllers but can be used by any NCI driver. This feature has been present in the HCI subsystem since 9a695d.

* net: Remove iocb argument from sendmsg and recvmsgYing Xue2015-03-022-8/+7Star
| | | | | | | | | | | | | | After TIPC doesn't depend on iocb argument in its internal implementations of sendmsg() and recvmsg() hooks defined in proto structure, no any user is using iocb argument in them at all now. Then we can drop the redundant iocb argument completely from kinds of implementations of both sendmsg() and recvmsg() in the entire networking stack.

* NFC: nci: Move NFCEE discovery logicChristophe Ricard2015-02-041-1/+7
| | | | | | | | | | | | | NFCEE_DISCOVER_CMD is a specified NCI command used to discover NFCEE IDs. Move nci_nfcee_discover() call to nci_discover_se() in order to guarantee: - NFCEE_DISCOVER_CMD run when the NCI state machine is initialized - NFCEE_DISCOVER_CMD is not run in case there is not discover_se hook defined by a NFC device driver.

* NFC: nci: Support all destinations type when creating a connectionChristophe Ricard2015-02-041-15/+33
| | | | | | | | | | | | The current implementation limits nci_core_conn_create_req() to only manage NCI_DESTINATION_NFCEE. Add new parameters to nci_core_conn_create() to support all destination types described in the NCI specification. Because there are some parameters with variable size dynamic buffer allocation is needed.

* NFC: nci: Change NCI state machine to LISTEN_ACTIVEChristophe Ricard2015-02-021-0/+8
| | | | | | | | | | | | When receiving an interface activation notification, if the RF interface is NCI_RF_INTERFACE_NFCEE_DIRECT, we need to ignore the following parameters and change the NCI state machine to NCI_LISTEN_ACTIVE. According to the NCI specification, the parameters should be 0 and shall be ignored. Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: nci: Add RF NFCEE action notification supportChristophe Ricard2015-02-021-0/+11
| | | | | | | | | | The NFCC sends an NCI_OP_RF_NFCEE_ACTION_NTF notification to the host (DH) to let it know that for example an RF transaction with a payment reader is done.

* NFC: Forward NFC_EVT_TRANSACTION to user spaceChristophe Ricard2015-02-023-0/+70
| | | | | | | | | | | | | | | | NFC_EVT_TRANSACTION is sent through netlink in order for a specific application running on a secure element to notify userspace of an event. Typically the secure element application counterpart on the host could interpret that event and act upon it. Forwarded information contains: - SE host generating the event - Application IDentifier doing the operation - Applications parameters Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* NFC: nci: Add HCI over NCI protocol supportChristophe Ricard2015-02-024-18/+722
| | | | | | | | | | | | | | | According to the NCI specification, one can use HCI over NCI to talk with specific NFCEE. The HCI network is viewed as one logical NFCEE. This is needed to support secure element running HCI only firmwares embedded on an NCI capable chipset, like e.g. the st21nfcb. There is some duplication between this piece of code and the HCI core code, but the latter would need to be abstracted even more to be able to use NCI as a logical transport for HCP packets.

* NFC: nci: Support logical connections managementChristophe Ricard2015-02-022-0/+85
| | | | | | | | | | In order to communicate with an NFCEE, we need to open a logical connection to it, by sending the NCI_OP_CORE_CONN_CREATE_CMD command to the NFCC. It's left up to the drivers to decide when to close an already opened logical connection.

* NFC: nci: Add NFCEE enabling and disabling supportChristophe Ricard2015-02-022-0/+34
| | | | | | | | | | NFCEEs can be enabled or disabled by sending the NCI_OP_NFCEE_MODE_SET_CMD command to the NFCC. This patch provides an API for drivers to enable and disable e.g. their NCI discoveredd secure elements.

* NFC: nci: Add NFCEE discover supportChristophe Ricard2015-02-023-0/+68
| | | | | | | | | | | | | | NFCEEs (NFC Execution Environment) have to be explicitly discovered by sending the NCI_OP_NFCEE_DISCOVER_CMD command. The NFCC will respond to this command by telling us how many NFCEEs are connected to it. Then the NFCC sends a notification command for each and every NFCEE connected. Here we implement support for sending NCI_OP_NFCEE_DISCOVER_CMD command, receiving the response and the potential notifications.

* NFC: nci: Add dynamic logical connections supportChristophe Ricard2015-02-024-33/+127
| | | | | | | | | | | | | The current NCI core only support the RF static connection. For other NFC features such as Secure Element communication, we may need to create logical connections to the NFCEE (Execution Environment. In order to track each logical connection ID dynamically, we add a linked list of connection info pointers to the nci_dev structure.

* NFC: hci: Change nfc_hci_send_response gate parameter to pipeChristophe Ricard2015-01-272-21/+8Star
| | | | | | | | | | | | | As there can be several pipes connected to the same gate, we need to know which pipe ID to use when sending an HCI response. A gate ID is not enough. Instead of changing the nfc_hci_send_response() API to something not aligned with the rest of the HCI API, we call nfc_hci_hcp_message_tx directly.

* NFC: hci: Add pipes table to reference them with a tuple {gate, host}Christophe Ricard2015-01-272-7/+35
| | | | | | | | | | In order to keep host source information on specific hci event (such as evt_connectivity or evt_transaction) and because 2 pipes can be connected to the same gate, it is necessary to add a table referencing every pipe with a {gate, host} tuple.

* NFC: hci: Change event_received handler gate parameter to pipeChristophe Ricard2015-01-271-1/+1
| | | | | | | | | | | | | Several pipes may point to the same CLF gate, so getting the gate ID as an input is not enough. For example dual secure element may have 2 pipes (1 for uicc and 1 for eSE) pointing to the connectivity gate. As resolving gate and host IDs can be done from a pipe, we now pass the pipe ID to the event received handler.

* netlink: make nlmsg_end() and genlmsg_end() voidJohannes Berg2015-01-181-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Contrary to common expectations for an "int" return, these functions return only a positive value -- if used correctly they cannot even return 0 because the message header will necessarily be in the skb. This makes the very common pattern of if (genlmsg_end(...) < 0) { ... } be a whole bunch of dead code. Many places also simply do return nlmsg_end(...); and the caller is expected to deal with it. This also commonly (at least for me) causes errors, because it is very common to write if (my_function(...)) /* error condition */ and if my_function() does "return nlmsg_end()" this is of course wrong. Additionally, there's not a single place in the kernel that actually needs the message length returned, and if anyone needs it later then it'll be very easy to just use skb->len there. Remove this, and make the functions void. This removes a bunch of dead code as described above. The patch adds lines because I did - return nlmsg_end(...); + nlmsg_end(...); + return 0; I could have preserved all the function's return values by returning skb->len, but instead I've audited all the places calling the affected functions and found that none cared. A few places actually compared the return value with <= 0 in dump functionality, but that could just be changed to < 0 with no change in behaviour, so I opted for the more efficient version. One instance of the error I've made numerous times now is also present in net/phonet/pn_netlink.c in the route_dumpit() function - it didn't check for <0 or <=0 and thus broke out of the loop every single time. I've preserved this since it will (I think) have caused the messages to userspace to be formatted differently with just a single message for every SKB returned to userspace. It's possible that this isn't needed for the tools that actually use this, but I don't even know what they are so couldn't test that changing this behaviour would be acceptable.

Linville says: ==================== pull request: wireless-next 2014-12-08 Please pull this last batch of pending wireless updates for the 3.19 tree... For the wireless bits, Johannes says: "This time I have Felix's no-status rate control work, which will allow drivers to work better with rate control even if they don't have perfect status reporting. In addition to this, a small hwsim fix from Patrik, one of the regulatory patches from Arik, and a number of cleanups and fixes I did myself. Of note is a patch where I disable CFG80211_WEXT so that compatibility is no longer selectable - this is intended as a wake-up call for anyone who's still using it, and is still easily worked around (it's a one-line patch) before we fully remove the code as well in the future." For the Bluetooth bits, Johan says: "Here's one more bluetooth-next pull request for 3.19: - Minor cleanups for ieee802154 & mac802154 - Fix for the kernel warning with !TASK_RUNNING reported by Kirill A. Shutemov - Support for another ath3k device - Fix for tracking link key based security level - Device tree bindings for btmrvl + a state update fix - Fix for wrong ACL flags on LE links" And... "In addition to the previous one this contains two more cleanups to mac802154 as well as support for some new HCI features from the Bluetooth 4.2 specification. From the original request: 'Here's what should be the last bluetooth-next pull request for 3.19. It's rather large but the majority of it is the Low Energy Secure Connections feature that's part of the Bluetooth 4.2 specification. The specification went public only this week so we couldn't publish the corresponding code before that. The code itself can nevertheless be considered fairly mature as it's been in development for over 6 months and gone through several interoperability test events. Besides LE SC the pull request contains an important fix for command complete events for mgmt sockets which also fixes some leaks of hci_conn objects when powering off or unplugging Bluetooth adapters. A smaller feature that's part of the pull request is service discovery support. This is like normal device discovery except that devices not matching specific UUIDs or strong enough RSSI are filtered out. Other changes that the pull request contains are firmware dump support to the btmrvl driver, firmware download support for Broadcom BCM20702A0 variants, as well as some coding style cleanups in 6lowpan & ieee802154/mac802154 code.'" For the NFC bits, Samuel says: "With this one we get: - NFC digital improvements for DEP support: Chaining, NACK and ATN support added. - NCI improvements: Support for p2p target, SE IO operand addition, SE operands extensions to support proprietary implementations, and a few fixes. - NFC HCI improvements: OPEN_PIPE and NOTIFY_ALL_CLEARED support, and SE IO operand addition. - A bunch of minor improvements and fixes for STMicro st21nfcb and st21nfca" For the iwlwifi bits, Emmanuel says: "Major works are CSA and TDLS. On top of that I have a new firmware API for scan and a few rate control improvements. Johannes find a few tricks to improve our CPU utilization and adds support for a new spin of 7265 called 7265D. Along with this a few random things that don't stand out." And... "I deprecate here -8.ucode since -9 has been published long ago. Along with that I have a new activity, we have now better a infrastructure for firmware debugging. This will allow to have configurable probes insides the firmware. Luca continues his work on NetDetect, this feature is now complete. All the rest is minor fixes here and there." For the Atheros bits, Kalle says: "Only ath10k changes this time and no major changes. Most visible are: o new debugfs interface for runtime firmware debugging (Yanbo) o fix shared WEP (Sujith) o don't rebuild whenever kernel version changes (Johannes) o lots of refactoring to make it easier to add new hw support (Michal) There's also smaller fixes and improvements with no point of listing here." In addition, there are a few last minute updates to ath5k, ath9k, brcmfmac, brcmsmac, mwifiex, rt2x00, rtlwifi, and wil6210. Also included is a pull of the wireless tree to pick-up the fixes originally included in "pull request: wireless 2014-12-03"...
