           Summary: Window Tracking not disabled

          Hardware: x86_64

            Status: NEW

Hi,

I have been conducting testing and I noticed that Window Tracking does not
appear to be disabled on a per connection level upon receipt.

Kernel: 4.1.17
Version: v1.4.3

To Replicate:

First ensure Configuration contains "TCPWindowTracking Off"
Ensure that /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_be_liberal is set to
"0"

Sync'ed connections out of window will fail. I tested this by triggering a
BGP
PoP switch.

Then Set /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_be_liberal to
"1".

It now works.
