Subject: 5.10 and 5.4 Backport Request: netfilter: conntrack: do not renew entry stuck in tcp SYN_SENT state
Date: Mon, 23 Jan 2023 11:01:47 -0800	[thread overview]
Message-ID: <CANZXNgMiuk=YwZCFO_u-L+20qKZT2xCGWfO7onou4XT+xQNUsA@mail.gmail.com> (raw)

PATCH_SUBJECT: netfilter: conntrack: do not renew entry stuck in tcp
SYN_SENT state
PATCH_COMMIT:  e15d4cdf27cb0c1e977270270b2cea12e0955edd

Reason for backport request:

We've had a few customers experience issues with dnat such that their
kubernetes processes are now unreachable. Because dnat rules fail to
update, kubernetes pod IPs won't resolve and traffic gets blackholed
causing any healthcheck service to kill and restart the pod. This
commit has been verified to fix the issue and the ask here is to
backport it to kernel versions v5.4 and v5.10.

Thanks
Nobel
