The article includes no details on what kernel patch they applied, what kernel version is in their AMI, or if they even have SACK enabled.<p>Guess you&#x27;re on your own, Team Databricks!

If true, this is unfortunate for anyone who was forced to apply their workaround in their systems, due to them being flagged by some &quot;compliance&quot; tool, even though they are not even accessible externally.

Regressions should be expected, because the unpatched code would have less checks to ensure correct operation.
