* mac802154: tx: change naming conventionAlexander Aring2014-10-26
| | | | | | | | This patch changes the naming convention of the tx functions like mac80211. Just with an 802154 instead 80211 inside the name. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

* mac802154: tx: use netdev print helpersAlexander Aring2014-10-26
| | | | | | | | This patch replace the pr_foo printout function to netdev_foo printout function. Inside the xmit handling, the interface is already known. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* mac802154: tx: don't allow if down while sync txAlexander Aring2014-10-26
| | | | | | | | This patch holds rtnl lock while sync xmit inside of workqueue. Otherwise we could down the interface while worker xmit handling. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* mac802154: tx: add support for xmit_async callbackAlexander Aring2014-10-26
| | | | | | | | | | | This patch renames the existsing xmit callback to xmit_sync and introduces an asynchronous xmit_async function. If ieee802154_ops doesn't provide the xmit_async callback, then we have a fallback to the xmit_sync callback.

* mac802154: tx: fix error handling while xmitAlexander Aring2014-10-26
| | | | | | | | In case of an error we should call kfree_skb instead of consume_skb which is called by ieee802154_xmit_complete function. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* mac802154: tx: use queue helpers in xmit workerAlexander Aring2014-10-26

* mac802154: add netdev qeue helpersAlexander Aring2014-10-26
| | | | | | | | | | This patch adds a new file net/mac802154/util.c which contains utility functions for drivers, etc. This file contains functions to start and stop queues for all virtual interfaces, this is useful for asynchronous handling by driver level.

* mac802154: tx: remove xmit channel context switchAlexander Aring2014-10-26
| | | | | | | | | | | | | | | | This patch removes the channel hopping feature before xmit. There are several issues to provide a real channel hopping (timing requirements, etc...). We don't have any known kernelspace protocol which really use this feature. And I don't know an real user of this feature. We simply drop this feature now. This patch removes also the hold of pib lock which isn't needed by any real driver xmit callback implementation.

* mac802154: tx: remove kmalloc in xmit hotpathAlexander Aring2014-10-26
| | | | | | | | | This patch removes the kmalloc allocation for workqueue data. This patch replaces the kmalloc and uses the control block of skb. The control block has enough space and isn't use by any other layer in this case. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

* mac802154: rename dev_workqueue to workqueueAlexander Aring2014-10-25

* mac802154: introduce IEEE802154_DEV_TO_SUB_IFAlexander Aring2014-10-25
| | | | | | | | | This function adds a wrapper to call netdev_priv to getting the sdata attribute. This is similar like the IEEE80211_DEV_TO_SUB_IF function inside wireless stack implementation.

* mac802154: introduce hw_to_local functionAlexander Aring2014-10-25

* mac802154: rename sdata slaves and slaves_mtxAlexander Aring2014-10-25

* mac802154: rename mac802154_sub_if_dataAlexander Aring2014-10-25
| | | | | | | | | Like wireless this structure should named ieee802154_sub_if_data and not mac802154_sub_if_data. This patch renames the struct and variables to sdata instead priv sometimes. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

| | | | | | | | | This patch rename the mac802154_priv to ieee802154_local. The mac802154_priv structure is like ieee80211_local and so we name it ieee802154_local. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

* ieee802154: move wpan-phy.h to cfg802154.hAlexander Aring2014-10-25
| | | | | | | | | | | The wpan-phy header contains the wpan_phy struct information. Later this header will be have similar function like cfg80211 header. The cfg80211 header contains the wiphy struct which is identically the wpan_phy struct inside 802.15.4 subsystem.

| | | | | | | | | | This patch moves the mac802154.h internal header to ieee802154_i.h like the wireless stack ieee80211_i.h file. This avoids confusing with the not internal header include/net/mac802154.h header. Additional we get the same naming conversion like mac80211 for this file.

| | | | | | | | | | The ieee802154_dev functionality contains various function for allocation and registration of an ieee802154_dev. This is equal to the net/mac80211/main.c file.

* Bluetooth: Add self-tests for SMP crypto functionsJohan Hedberg2014-10-25

* Bluetooth: Add skeleton for SMP self-testsJohan Hedberg2014-10-25
| | | | | | | | | | This patch adds a basic skeleton for SMP self-tests. The tests are put behind a new configuration option since running them will slow down the boot process. For now there are no actual tests defined but those will come in a subsequent patch. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Pass only crypto context to SMP crypto functionsJohan Hedberg2014-10-25
| | | | | | | | | | | | In order to make unit testing possible we need to make the SMP crypto functions only take the crypto context instead of the full SMP context (the latter would require having hci_dev, hci_conn, l2cap_chan, l2cap_conn, etc around). The drawback is that we no-longer get the involved hdev in the debug logs, but this is really the only way to make simple unit tests for the code.

* 6lowpan: Use skb_cow in IPHC decompression.Martin Townsend2014-10-25
| | | | | | | | | | | | | | | Currently there are potentially 2 skb_copy_expand calls in IPHC decompression. This patch replaces this with one call to skb_cow which will check to see if there is enough headroom first to ensure it's only done if necessary and will handle alignment issues for cache. As skb_cow uses pskb_expand_head we ensure the skb isn't shared from bluetooth and ieee802.15.4 code that use the IPHC decompression.

* Bluetooth: Improve RFCOMM __test_pf macro robustnessSzymon Janc2014-10-25

* Bluetooth: Fix RFCOMM NSC responseSzymon Janc2014-10-25
| | | | | | | | | | | | | | | | | | | | rfcomm_send_nsc expects CR to be either 0 or 1 since it is later passed to __mcc_type macro and shitfed. Unfortunatelly CR extracted from received frame type was not sanitized and shifted value was passed resulting in bogus response. Note: shifted value was also passed to other functions but was used only in if satements so this bug appears only for NSC case. The CR bit in the value octet shall be set to the same value as the CR bit in the type field octet of the not supported command frame but the CR bit for NCS response should be set to 0 since it is always a response. This was affecting TC_RFC_BV_25_C PTS qualification test. Signed-off-by: Szymon Janc <szymon.janc@tieto.com> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Defer connection-parameter removal when unpairingAlfonso Acosta2014-10-25
| | | | | | | | | | | | | | | | | | Systematically removing the LE connection parameters and autoconnect action is inconvenient for rebonding without disconnecting from userland (i.e. unpairing followed by repairing without disconnecting). The parameters will be lost after unparing and userland needs to take care of book-keeping them and re-adding them. This patch allows userland to forget about parameter management when rebonding without disconnecting. It defers clearing the connection parameters when unparing without disconnecting, giving a chance of keeping the parameters if a repairing happens before the connection is closed.

* Bluetooth: Include ADV_IND report in Device Connected eventAlfonso Acosta2014-10-25
| | | | | | | | | | | | | | | | | | | There are scenarios when autoconnecting to a device after the reception of an ADV_IND report (action 0x02), in which userland might want to examine the report's contents. For instance, the Service Data might have changed and it would be useful to know ahead of time before starting any GATT procedures. Also, the ADV_IND may contain Manufacturer Specific data which would be lost if not propagated to userland. In fact, this patch results from the need to rebond with a device lacking persistent storage which notifies about losing its LTK in ADV_IND reports. This patch appends the ADV_IND report which triggered the autoconnection to the EIR Data in the Device Connected event.
