linux-toradex.git/net/ieee802154, branch v4.9.21 Linux kernel for Apalis and Colibri modules ieee802154: 6lowpan: fix intra pan id check 2016-07-08T11:23:12+00:00 Alexander Aring aar@pengutronix.de 2016-07-06T21:32:26+00:00 0ea0b9af9b7599ada307258dc841f4300873e8a1 The RIOT-OS stack does send intra-pan frames but don't set the intra pan flag inside the mac header. It seems this is valid frame addressing but inefficient. Anyway this patch adds a new function for intra pan addressing, doesn't matter if intra pan flag or source and destination are the same. The newly introduction function will be used to check on intra pan addressing for 6lowpan. Signed-off-by: Alexander Aring <aar@pengutronix.de> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

ieee802154: allow netns create of lowpan interface 2016-07-08T10:20:57+00:00 Alexander Aring aar@pengutronix.de 2016-06-18T08:45:35+00:00 1c5bf998b3dca0599a2cce885619ffc06fc594df This patch reverts commit f9d1ce8f81eb ("ieee802154: fix netns settings"). The lowpan interface need to be created inside the net namespace where the wpan interface is available. The wpan namespace can be changed only by nl802154 before. Without this patch it's not possible to create a lowpan interface for a wpan interface which isn't inside init_net namespace.
