Sun Austin 171c43dca8 Fix Periodic message loss between VIM and Openstack REST APIs 
set net.ipv4.tcp_tw_recycle=1 to avoid dnat conntrack invalid

The probe connection action before going to time_wait state.
Probe connection
controller               pod        TCP FLAG      SEQ           ACK
controller:50538 ---> endpoint:9292     SYN       2707980036       0
controller:50538 <--- endpoint:9292   SYN ACK     1599414185
2707980037
controller:50538 ---> endpoint:9292     ACK       2707980037
1599414186
controller:50538 ---> endpoint:9292   FIN ACK     2707980037
1599414186
controller:50538 <--- endpoint:9292     ACK       1599414186
2707980038
controller:50538 <--- endpoint:9292   FIN ACK     1599414186
2707980038
controller:50538 ---> endpoint:9292     ACK       2707980038
1599414187

And for the curl command connection with same port 50538: it will be
like
controller              pod          TCP FLAG         SEQ          ACK
controller:50538 -->  service:9292     SYN        2917708674        0
controller:50538 --> endpoint:9292     SYN        2917708674        0
controller:24479 <-- endpoint:9292   SYN ACK      2742336307
2917708675
controller:50538 <-- endpoint:9292   SYN ACK      2742336307
2917708675
controller:50538 -->  service:9292     ACK        2707980038
1599414187
controller:50538 -->  service:9292     ACK        2707980038
1599414187
controller:50538 -->  service:9292     ACK(DROP)  2707980038
1599414187

The last ACK(controller:50538-->service:9292) SEQ and ACK is same as
Probe TIME_WAIT latest ACK’s.
from
https://github.com/torvalds/linux/blob/v3.10/net/ipv4/tcp_ipv4.c#L2002 ,
it only check (des ip , des port, src ip, and src port).Because this is
not
 a correct SEQ/ACK , then it is set invalid and then dropped.

If enabling tcp_tw_recycle, the previous socket should be already
closed, then the issue should be gone.
