Hi, I hope I'm doing this correctly, as per https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html, Option 2. :) Subject of the patch: tcp: enforce receive buffer memory limits by allowing the tcp window to shrink Full details including reproducers, impact, tests are available here: https://blog.cloudflare.com/unbounded-memory-usage-by-tcp-for-receive-buffers-and-how-we-fixed-it/ commit ID: b650d953cd391595e536153ce30b4aab385643ac Why I think it should be applied: - linux TCP sessions are allocating more memory than they should - the kernel drops incoming packets which it should not drop - large amounts of memory can be saved (see https://blog.cloudflare.com/unbounded-memory-usage-by-tcp-for-receive-buffers-and-how-we-fixed-it/#memory) What kernel versions you wish it to be applied to: 6.1.x (stable). Thank you! :)
Queued up, thanks. -- Thanks, Sasha
