However, I would like to take back a part of my previous response, where I informed you about the "xtsproxy" kernel module. Please don't try to use it.

So a proper backport is required, even though the Cloudflare patch applies as-is. https://github.com/zen-kernel/zen-kernel/issues/306 https://github.com/zen-kernel/zen-kernel/issues/310 -- Alexander E.
