ieee802154: add short address helpers

2016-04-13T08:41:08Z

This patch introduce some short address handling functionality into ieee802154 headers. Reviewed-by: Stefan Schmidt Signed-off-by: Alexander Aring Acked-by: Jukka Rissanen Signed-off-by: Marcel Holtmann

mac802154: use put and get unaligned functions

2016-03-10T18:51:28Z

This patch removes the swap pointer and memmove functionality. Instead we use the well known put/get unaligned access with specific byte order handling. Signed-off-by: Alexander Aring Suggested-by: Marc Kleine-Budde Signed-off-by: Marcel Holtmann

mac802154: fix mac header length check

2016-02-23T19:29:39Z

I got report about that sometimes the WARN_ON occurs there which should never happen. I came to the conclusion that the mac header is there but inside the headroom of skb. The skb->len information doesn't contain the information about the headroom length and skb->len is lesser than two. We check now if the skb_mac_header pointer is set and the room between mac header pointer and tail pointer. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

6lowpan: cleanup lowpan_header_decompress

2015-10-20T22:49:24Z

This patch changes the lowpan_header_decompress function by removing inklayer related information from parameters. This is currently for supporting short and extended address for iphc handling in 802154. We don't support short address handling anyway right now, but there exists already code for handling short addresses in lowpan_header_decompress. The address parameters are also changed to a void pointer, so 6LoWPAN linklayer specific code can put complex structures as these parameters and cast it again inside the generic code by evaluating linklayer type before. The order is also changed by destination address at first and then source address, which is the same like all others functions where destination is always the first, memcpy, dev_hard_header, lowpan_header_compress, etc. This patch also moves the fetching of iphc values from 6LoWPAN linklayer specific code into the generic branch.

mac802154: check on len instead mac_len

2015-09-30T11:22:11Z

This patch change the length check to len instead of mac_len for checking if the frame control field is available to dereference. We need to change it because I saw issues with af_packet raw sockets and the mrf24j40 which calls this functionality. The raw socket functionality doesn't set the mac_len but resets the skb_mac_header to skb->data which is still correct. The issue occur at mrf24j40 only, because the driver need to evaluate the fc fields. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

ieee802154: change needed headroom/tailroom

2015-09-22T09:51:20Z

This patch cleanups needed_headroom, needed_tailroom and hard_header_len fields for wpan and lowpan interfaces. For wpan interfaces the worst case mac header len should be part of needed_headroom, currently this is set as hard_header_len, but hard_header_len should be set to the minimum header length which xmit call assumes and this is the minimum frame length of 802.15.4. The hard_header_len value will check inside send callbacl of AF_PACKET raw sockets. For lowpan interfaces, if fragmentation isn't needed the skb will call dev_hard_header for 802154 layer and queue it afterwards. This happens without new skb allocation, so we need the same headroom and tailroom lengths like 802154 inside 802154 6lowpan layer. At least we assume as minimum header length an ipv6 header size.

ieee802154: 6lowpan: check on valid 802.15.4 frame

This patch adds frame control checks to check if the received frame is something which could contain a 6LoWPAN packet. Reviewed-by: Stefan Schmidt Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

mac802154: do not export ieee802154_rx()

2015-07-23T15:10:50Z

Right now there are no other users for ieee802154_rx() in kernel. So lets remove EXPORT_SYMBOL() for this. Also it moves the function prototype from global header file to local header file. Signed-off-by: Varka Bhadram Acked-by: Alexander Aring Signed-off-by: Marcel Holtmann

mac802154: fix flags BIT definitions order

This patch fixes commits ("mac802154: cleanup ieee802154 hardware flags") bcbfd2078d9b11277d9c9ce0c30ba73c750503c9 and ("mac802154: cleanup address filtering flags") 6b70a43c7e0202cf285c864bc9f20f607c42e432 by starting the flags definitions at BIT(0) which is same like the previous behaviour.

mac802154: change pan_coord type to bool

To indicate if it's a coordinator or not a bool is enough. There should no more values available which represent some other state. Signed-off-by: Alexander Aring Reviewed-by: Varka Bhadram Signed-off-by: Marcel Holtmann
