This series aims to fix incorrect return values in lowpan_rcv To achieve this it also refactors the receive path to 1) free skb only from lowpan_rcv and not functions that it calls 2) move skb delivery from IPHC
I have only compile tested the changes for bluetooth as I don't have any HW available so would be grateful for any testing from the Bluetooth developers. I have done some minimal testing for IEEE802.15.4 Signed-off-by: Martin Townsend <martin.towns...@xsilon.com> --- v1 -> v2: * combined first two patches into one. * split out renaming of process_data into a new patch * re-use err in lowpan_process_data and remove err_ret local variable. * removed third patch as applies to linux-wpan v2 -> v3: (Updated from Alexander Aring's Review) * re-use err hadn't been included in patch. * fixed some 'goto drop' cases in lowpan_rcv that should be 'goto drop skb' * handle error codes when returning from lowpan_frag_rcv. * Refactored lowpan_give_skb_to_devices so it consumes or free's skb and then only returns NET_RX status codes. v3 -> v4: (Updated from Jukka Rissanen and Alexander Aring's Reviews) * Removed use of double skb pointer in decompress routines in favour of using pskb_expand_head to obtain more headroom. Requires an uncloned skb so the calling functions now ensure this. * prefer consume_skb on non error conditions. * removed spurious setting of ret in lowpan_rcv Martin Townsend (1): 6lowpan: fix incorrect return values in lowpan_rcv include/net/6lowpan.h | 9 +++-- net/6lowpan/iphc.c | 92 ++++++++++++++++--------------------------- net/bluetooth/6lowpan.c | 52 ++++++++++++++++-------- net/ieee802154/6lowpan_rtnl.c | 66 ++++++++++++++++++++----------- 4 files changed, 117 insertions(+), 102 deletions(-) -- 1.9.1 ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
