Hi, As a part of research activities in the Embedded Systems - Open Platform Group from Siemens Corporate Technology we are working on adding support for the IEEE 802.15.4 Wireless Personal Area Networks to the Linux. Our current implementation is neither certified nor even feature complete. However we'd like to present current state of our patchset to the Linux developers community to gain comments, fixes, ideas, etc. This is not yet a pull request, but more like an RFC. The project page is available at http://apps.sourceforge.net/trac/linux-zigbee with source code of kernel part available from git at http://zigbee-linux.git.sourceforge.net, mirrored for convenience at git://git.kernel.org/pub/scm/linux/kernel/git/lumag/lowpan.git The source code for userspace utils is available from git at http://linux-zigbee.git.sourceforge.net/ Several comments about our implementation: * As with 802.11 there are two types of devices: the smart ones that implement most parts of the protocol by themselves and more or less dumb ones which simply send and receive what they are told. Currently we do only support the second type of devices (SoftMAC) * The implementation is split between code driving radio, (master, mwpanX interface: mdev.c), code processing frames according the IEEE 802.15.4 rules (slave wpanX devices) and finally sockets (af_ieee802154.c, dgram.c, raw.c). * We do present two example drivers using our stack. One is purely virtual one either looping the packets back or connecting several virtual interfaces (the one at fakelb.c), and the driver for the Freescale MC13192 evaluation boards (13192-SARD, 13192-EVK) using our custom firmware (currently only available at request, we are working on publishing it). The driver for the Atmel at86rf230/at86rf231 chips will follow in several weeks. The following changes since commit 59a3759d0fe8d969888c741bb33f4946e4d3750d: Linus Torvalds (1): Linux 2.6.30-rc7 are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/lumag/lowpan.git for-review-v0 Dmitry Eremin-Solenikov (5): Add constants for the ieee 802.15.4/ZigBee stack net: add IEEE 802.15.4 partial implementation ieee802154: add socket address family code ieee802154: add virtual loopback driver ieee802154: add serial dongle driver drivers/Makefile | 1 + drivers/ieee802154/Kconfig | 26 + drivers/ieee802154/Makefile | 4 + drivers/ieee802154/fakelb.c | 335 +++++++++++ drivers/ieee802154/serial.c | 1001 ++++++++++++++++++++++++++++++++ drivers/net/Kconfig | 2 + include/linux/if.h | 2 + include/linux/if_arp.h | 2 + include/linux/if_ether.h | 2 + include/linux/socket.h | 6 +- include/linux/tty.h | 3 +- include/net/ieee802154/af_ieee802154.h | 65 ++ include/net/ieee802154/beacon.h | 53 ++ include/net/ieee802154/beacon_hash.h | 40 ++ include/net/ieee802154/const.h | 696 ++++++++++++++++++++++ include/net/ieee802154/crc.h | 38 ++ include/net/ieee802154/dev.h | 107 ++++ include/net/ieee802154/mac_def.h | 96 +++ include/net/ieee802154/netdev.h | 74 +++ include/net/ieee802154/nl.h | 166 ++++++ include/net/ieee802154/phy.h | 117 ++++ net/Kconfig | 1 + net/Makefile | 1 + net/core/dev.c | 6 +- net/core/sock.c | 3 + net/ieee802154/Kconfig | 12 + net/ieee802154/Makefile | 6 + net/ieee802154/af_ieee802154.c | 312 ++++++++++ net/ieee802154/beacon.c | 251 ++++++++ net/ieee802154/beacon_hash.c | 105 ++++ net/ieee802154/crc.c | 73 +++ net/ieee802154/dev.c | 935 +++++++++++++++++++++++++++++ net/ieee802154/dgram.c | 372 ++++++++++++ net/ieee802154/mac_cmd.c | 226 +++++++ net/ieee802154/main.c | 175 ++++++ net/ieee802154/mdev.c | 189 ++++++ net/ieee802154/netlink.c | 637 ++++++++++++++++++++ net/ieee802154/raw.c | 249 ++++++++ net/ieee802154/scan.c | 211 +++++++ net/ieee802154/start.c | 46 ++ 40 files changed, 6642 insertions(+), 4 deletions(-) create mode 100644 drivers/ieee802154/Kconfig create mode 100644 drivers/ieee802154/Makefile create mode 100644 drivers/ieee802154/fakelb.c create mode 100644 drivers/ieee802154/serial.c create mode 100644 include/net/ieee802154/af_ieee802154.h create mode 100644 include/net/ieee802154/beacon.h create mode 100644 include/net/ieee802154/beacon_hash.h create mode 100644 include/net/ieee802154/const.h create mode 100644 include/net/ieee802154/crc.h create mode 100644 include/net/ieee802154/dev.h create mode 100644 include/net/ieee802154/mac_def.h create mode 100644 include/net/ieee802154/netdev.h create mode 100644 include/net/ieee802154/nl.h create mode 100644 include/net/ieee802154/phy.h create mode 100644 net/ieee802154/Kconfig create mode 100644 net/ieee802154/Makefile create mode 100644 net/ieee802154/af_ieee802154.c create mode 100644 net/ieee802154/beacon.c create mode 100644 net/ieee802154/beacon_hash.c create mode 100644 net/ieee802154/crc.c create mode 100644 net/ieee802154/dev.c create mode 100644 net/ieee802154/dgram.c create mode 100644 net/ieee802154/mac_cmd.c create mode 100644 net/ieee802154/main.c create mode 100644 net/ieee802154/mdev.c create mode 100644 net/ieee802154/netlink.c create mode 100644 net/ieee802154/raw.c create mode 100644 net/ieee802154/scan.c create mode 100644 net/ieee802154/start.c -- With best wishes Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
