ip6: fix l4 checksum with hop-by-hop header
L4 checksums for IPv6 should be calculated using a pseudo header that includes the source/destination addresses, payload length, and payload protocol. ip6_tcp_udp_icmp_compute_checksum() was using the payload length and protocol from the IPv6 header. If there is a hop-by-hop header (or any other extension header), the payload length used for the pseudo header should only include the upper layer header and payload and not the extension header bytes. Same deal with the protocol, the upper layer next header value should be used instead of the extension header. Type: fix Fixes: cb9cadad57 Change-Id: Ifa2c9ad41c0fc4eea674f0671255b637c8e01f71 Signed-off-by: Matthew Smith <mgsmith@netgate.com>
