[Swan-dev] what git commit or patch fixes the maximum number of retransmit reached problem after libreswan 3.15

[CHEN, JIANFU]

Hi,

I am current using libreswan 3.15. And found that after libreswan restarts, if the peer side not reachable after about 1 minutes, it gives a message
Max number of retransmission reached, and will not try to connect to the peer side anymore even if later the peer side is reachable. The message is shown as below:

Jun  3 16:28:28 R9 pluto[23315]: "net22" #1: initiating Main Mode
Jun  3 16:29:32 R9 pluto[23315]: "net22" #1: max number of retransmissions (8) reached STATE_MAIN_I1.  No response (or no acceptable response) to our first IKEv1 message
Jun  3 16:29:32 R9 pluto[23315]: "net22" #1: deleting state #1 (STATE_MAIN_I1)

I tried the libreswan 3.17, and found the problem has been fixed. But for some reason, we plan to still use libreswan 3.15. But plan to fix this problem to add a patch based on libreswan 3.15.

Does anyone know which patch or git commit fixes this problem.

Thanks,

Jeff
