In __udp_lib_checksum_complete check if checksum is being done over all the data (len is equal to skb->len) and if it is call __skb_checksum_complete instead of __skb_checksum_complete_head. This allows checksum to be saved in checksum complete. Signed-off-by: Tom Herbert <therbert@google.com> --- include/net/udp.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-)
