Jakub,
I just did a batch of networking -stable submissions, however I ran into some troubles with the various TLS backports. I was able to backport commit 414776621d10 ("net/tls: prevent skb_orphan() from leaking TLS plain text with offload") to v5.2 but not to v4.19 I was not able to backport neither d85f01775850 ("net: tls, fix sk_write_space NULL write when tx disabled") nor commit 57c722e932cf ("net/tls: swap sk_write_space on close") to any release. It seems like there are a bunch of dependencies and perhaps other fixes. I suspect you've triaged through this already on your side for other reasons, so perhaps you could help come up with a sane set of TLS bug fix backports that would be appropriate for -stable? Thanks!
