There are some cards that support SCTP checksum offloading. When using these cards with IPSec or forcing IP fragmentation of SCTP traffic, the checksum is computed incorrectly due to the fact that xfrm and IP/IPv6 fragmentation code do not know that this is SCTP traffic and do not know that checksum has to be computed differently. To fix this, we let SCTP detect these conditions and perform software checksum calculation. Fan Du (1): sctp: Use software crc32 checksum when xfrm transform will happen. Vlad Yasevich (2): net: dst: provide accessor function to dst->xfrm sctp: Perform software checksum if packet has to be fragmented. include/net/dst.h | 12 ++++++++++++ net/sctp/output.c | 3 ++- 2 files changed, 14 insertions(+), 1 deletion(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-sctp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
