* mac802154: fix duplicate #include headersJean Sacren2014-04-07
| | | | | | | | | | | | | | | | | | | The commit e6278d92005e ("mac802154: use header operations to create/parse headers") included the header net/ieee802154_netdev.h which had been included by the commit b70ab2e87f17 ("ieee802154: enforce consistent endianness in the 802.15.4 stack"). Fix this duplicate #include by deleting the latter one as the required header has already been in place.

* mac802154: make csma/cca parameters per-wpanPhoebe Buckheister2014-04-01
| | | | | | | | | | | | Commit 9b2777d6089bcd (ieee802154: add TX power control to wpan_phy) and following erroneously added CSMA and CCA parameters for 802.15.4 devices as PHY parameters, while they are actually MAC parameters and can differ for any two WPAN instances. Since it is now sensible to have multiple WPAN devices with differing CSMA/CCA parameters, make these parameters MAC parameters instead.

* mac802154: allow only one WPAN to be up at any given timePhoebe Buckheister2014-04-01
| | | | | | | | | | | | | | | All 802.15.4 PHY devices with drivers in tree can support only one WPAN at any given time, yet the stack allows arbitrarily many WPAN devices to be created and up at the same time. This cannot work with what the hardware provides, and in the current implementation, provides an easy DoS vector to any process on the system that may call socket() and sendmsg(). Thus, allow only one WPAN per PHY to be up at once, just like mac80211 does for managed devices. Signed-off-by: Phoebe Buckheister <phoebe.buckheister@itwm.fraunhofer.de> Signed-off-by: David S.

* ieee802154: add proper length checks to header creationsPhoebe Buckheister2014-03-14
| | | | | | | | | | | Have mac802154 header_ops.create fail with -EMSGSIZE if the length passed will be too large to fit a frame. Since 6lowpan will ensure that no packet payload will be too large, pass a length of 0 there. 802.15.4 dgram sockets will also return -EMSGSIZE on payloads larger than the device MTU instead of -EINVAL.

* mac802154: use header operations to create/parse headersPhoebe Buckheister2014-03-14
| | | | | | | | | | | | | | | | | Use the operations on 802.15.4 header structs introduced in a previous patch to create and parse all headers in the mac802154 stack. This patch reduces code duplication between different parts of the mac802154 stack that needed information from headers, and also fixes a few bugs that seem to have gone unnoticed until now: * 802.15.4 dgram sockets would return a slightly incorrect value for the SIOCINQ ioctl * mac802154 would not drop frames with the "security enabled" bit set, even though it does not support security, in violation of the standard Signed-off-by: Phoebe Buckheister <phoebe.buckheister@itwm.fraunhofer.de> Signed-off-by: David S.

* ieee802154: enforce consistent endianness in the 802.15.4 stackPhoebe Buckheister2014-03-14
| | | | | | | | | | | | | | Enable sparse warnings about endianness, replace the remaining fields regarding network operations without explicit endianness annotations with such that are annotated, and propagate this through the entire stack. Uses of ieee802154_addr_sa are not changed yet, this patch is only concerned with all other fields (such as address filters, operation parameters and the likes).

* ieee802154: rename struct ieee802154_addr to *_saPhoebe Buckheister2014-03-14
| | | | | | | | | | | The struct as currently defined uses host byte order for some fields, and most big endian/EUI display byte order for other fields. Inside the stack, endianness should ideally match network byte order where possible to minimize the number of byteswaps done in critical paths, but this patch does not address this; it is only preparatory.

* ieee802154: add netlink APIs for smartMAC configurationPhoebe Buckheister2014-02-17
| | | | | | | | | | | | | | | | | | | | | | | Introduce new netlink attributes for SET_PHY_ATTRS: * CSMA minimal backoff exponent * CSMA maximal backoff exponent * CSMA retry limit * frame retransmission limit The CSMA attributes shall correspond to minBE, maxBE and maxCSMABackoffs of 802.15.4, respectively. The frame retransmission shall correspond to maxFrameRetries of 802.15.4, unless given as -1: then the old behaviour of the stack shall apply. For RF2xy, the old behaviour is to not do channel sensing at all and simply send *right now*, which is not intended behaviour for most applications and actually prohibited for some channel/page combinations. For all values except frame retransmission limit, the defaults of 802.15.4 apply. Frame retransmission limits are set to -1 to indicate backward-compatible behaviour.

* ieee802154: add support for setting CCA energy detection levelsPhoebe Buckheister2014-02-17
| | | | | | | | | | | | | | | | | Since three of the four clear channel assesment modes make use of energy detection, provide an API to set the energy detection threshold. Driver support for this is available in at86rf230 for the RF212 chips. Since for these chips the minimal energy detection threshold depends on page and channel used, add a field to struct at86rf230_local that stores the minimal threshold. Actual ED thresholds are configured as offsets from this value. For RF212, setting the ED threshold will not work before a channel/page has been set due to the dependency of energy detection in the chip and the actual channel/page selected.

| | | | | | | | | | | | | | | | Replace the current u8 transmit_power in wpan_phy with s8 transmit_power. The u8 field contained the actual tx power and a tolerance field, which no physical radio every used. Adjust sysfs entries to keep compatibility with userspace, give tolerances of +-1dB statically there. This patch only adds support for this in the at86rf230 driver and the RF212 chip. Configuration calculation for RF212 is also somewhat basic, but does the job - the RF212 datasheet gives a large table with suggested values for combinations of TX power and page/channel, if this does not work well, we might have to copy the whole table.

Consider that traffic on mac802154 devices will often be 6LoWPAN, and a full-length (1280 octet) IPv6 packet will fragment into 15 6LoWPAN fragments (because the MTU of IEEE 802.15.4 is 127). A 300-packet queue is really 20 full-length IPv6 packets. With a queue length of 10, an entire IPv6 packet was unable to get queued at one time, causing fragments to be dropped, and making reassembly impossible.

Since many IEEE 802.15.4 devices have no output buffer, and since the mac802154 xmit() function is designed to block, netif_stop_queue() is called after each packet.

Devices which support hardware ack and retry (which include all devices currently supported by mainline), will automatically retry sending the packet (in the hardware) up to 3 times, per the 802.15.4 spec.
