Sure. I tried that and it looks OK.
The truth is that I don't understand this code very well. I'm just writing
patches based on static analysis. Here is the output from window1:
$ sudo ip xfrm mon
src 172.16.2.0/24 dst 172.16.1.0/24
dir fwd priority 0
tmpl src 192.168.2.100 dst 192.168.1.100
proto esp reqid 0 mode tunnel
Deleted src 172.16.2.0/24 dst 172.16.1.0/24
dir fwd priority 0
tmpl src 192.168.2.100 dst 192.168.1.100
proto esp reqid 0 mode tunnel
There aren't any messages in dmesg either.
regards,
dan carpenter
