ieee802154: add netns support

2016-07-08T10:20:57Z

This patch adds netns support for 802.15.4 subsystem. Most parts are copy&pasted from wireless subsystem, it has the identically userspace API. Cc: Nicolas Dichtel Reviewed-by: Stefan Schmidt Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

nl802154: add support for security layer

2015-09-30T11:16:44Z

This patch adds support for accessing mac802154 llsec implementation over nl802154. I added for a new Kconfig entry to provide this functionality CONFIG_IEEE802154_NL802154_EXPERIMENTAL. This interface is still in development. It provides to change security parameters and add/del/dump entries of security tables. Later we can add also a get to get an entry by unique identifier.

ieee802154: introduce wpan_dev_header_ops

2015-09-22T09:51:20Z

The current header_ops callback structure of net device are used mostly from 802.15.4 upper-layers. Because this callback structure is a very generic one, which is also used by e.g. DGRAM AF_PACKET sockets, we can't make this callback structure 802.15.4 specific which is currently is. I saw the smallest "constraint" for calling this callback with dev_hard_header/dev_parse_header by AF_PACKET which assign a 8 byte array for address void pointers. Currently 802.15.4 specific protocols like af802154 and 6LoWPAN will assign the "struct ieee802154_addr" as these parameters which is greater than 8 bytes. The current callback implementation for header_ops.create assumes always a complete "struct ieee802154_addr" which AF_PACKET can't never handled and is greater than 8 bytes. For that reason we introduce now a "generic" create/parse header_ops callback which allows handling with intra-pan extended addresses only. This allows a small use-case with AF_PACKET to send "somehow" a valid dataframe over DGRAM. To keeping the current dev_hard_header behaviour we introduce a similar callback structure "wpan_dev_header_ops" which contains 802.15.4 specific upper-layer header creation functionality, which can be called by wpan_dev_hard_header.

ieee802154: add ack request default handling

2015-08-10T18:43:06Z

This patch introduce a new mib entry which isn't part of 802.15.4 but useful as default behaviour to set the ack request bit or not if we don't know if the ack request bit should set. This is currently used for stacks like IEEE 802.15.4 6LoWPAN. Reviewed-by: Stefan Schmidt Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

ieee802154: 6lowpan: remove multiple lowpan per wpan support

2015-08-10T18:43:06Z

We currently supports multiple lowpan interfaces per wpan interface. I never saw any use case into such functionality. We drop this feature now because it's much easier do deal with address changes inside the under laying wpan interface. This patch removes the multiple lowpan interface and adds a lowpan_dev netdev pointer into the wpan_dev, if this pointer isn't null the wpan interface belongs to the assigned lowpan interface.

cfg802154: add PM hooks

mac802154: use atomic ops for sequence incrementation

2015-05-23T15:57:08Z

This patch will use atomic operations for sequence number incrementation while MAC header generation. Upper layers like af_802154 or 6LoWPAN could call this function in a parallel context while generating 802.15.4 MAC header before queuing into wpan interfaces transmit queue.
