Subject: [PATCHv3 net-next 0/6] 6lowpan: address uncompression fixes
Date: Fri, 16 Aug 2013 21:59:53 +0200	[thread overview]
Message-ID: <1376683199-10370-1-git-send-email-alex.aring@gmail.com> (raw)

The current implementation to uncompress addresses in a 6lowpan header
is completely broken.

This patch series fixes the parsing of addresses in a 6lowpan header.
It contains a major rewrite of the uncompress address function to parse
the address in a correct way.

Tested with the ravenusbstick(contiki 6LoWPAN stack) and beaglebone
(linux 6LoWPAN Stack) on the other side. The linux side contains all
possible addresses for the uncompression cases. Then I type a ping6 for
each case and lookup in wireshark and dmesg the correct reconstruction.

Please apply this patch series on net-next in order 1/7 to 7/7.

Changes since v3:
 - Fix byte ordering problem in uncompression of short-address.
   Thanks for this hint.
 - drop pr_debug before lowpan_raw_dump_inline

Changes since v2:
 - Add tags for net-next
 - Change commit msg in Patch 1/6 that this patch depends for the following
   patches

Alexander Aring (5):
  6lowpan: init ipv6hdr buffer to zero
  6lowpan: introduce lowpan_fetch_skb function
  6lowpan: add function to uncompress multicast addr
  6lowpan: lowpan_uncompress_addr with address_mode
  6lowpan: handle context based source address
