The filename of the patch is: net-make-tcp_allowed_congestion_control-readonly-in-non-init-netns.patch and it can be found in the queue-5.10 subdirectory.

If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

Hi Greg,

Thanks for picking this into the stable trees.

There's an earlier, somewhat related fix, which is only on net-next:

2671fa4dc010 ("netfilter: conntrack: Make global sysctls readonly in non-init netns")

That probably could have been on "net", but it followed this other commit which was not strictly a bug-fix. It's additional logic to detect bugs like the former:

31c4d2f160eb ("net: Ensure net namespace isolation of sysctls")

Here's the series on Patchwork: https://patchwork.kernel.org/project/netdevbpf/cover/20210412042453.32168-1-...

I'm not yet sure where the threshold is for inclusion into "net" or "stable". Could you please take a look and see if the first (or both) of these should be included into the stable trees? If so, please feel free to pick them yourself, or let me know which patches I should send to "stable".

Thanks! Jonathon Reinhart
