the tcp_sock:delivered has inconsistent accounting for SYN and FIN. 1. it counts pure FIN 2. it counts pure SYN 3. it counts SYN-data twice 4. it does not count SYN-ACK For congestion control perspective it does not matter much as C.C. only cares about the difference not the aboslute value. But the next patch would export this field to user-space so it's better to report the absolute value w/o these caveats. This patch counts SYN, SYN-ACK, or SYN-data delivery once always in the "delivered" field. Signed-off-by:
