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 David Hauweele (1): 6lowpan: Fix fragmentation with link-local compressed addresses net/ieee802154/6lowpan.c | 286 +++++++++++++++++++++++++++++++---------------- net/ieee802154/6lowpan.h | 20 +++- 2 files changed, 204 insertions(+), 102 deletions(-) -- 1.8.3.3 ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
