[Package Request] - Kernel backport of 3584718cf2ec bugfix status

[nantiferov]

Hi, Sorry if this is a wrong type of request of wrong repo. I selected what looked like most matching.

What package is missing from Amazon Linux 2023? Please describe and include package name.

I would like to know if this fix to kernel was backported to 6.1, which is used in AL2023 Bug affects network stack on kernel v6.0 until v6.9 on arm64/Graviton hardware and could cause slowdown of network stack, including complete outage refusing new connections.

I wasn't able to find repo from which kernel is build for AL2023, so I created issue here.

Is this an update to existing package or new package request?

I guess update of kernel

Is this package available in Amazon Linux 2? If it is available via external sources such as EPEL, please specify.

N/A

Any additional information you'd like to include. (use-cases, etc)

Basically, in linux kernel version v6.0 was introduced bug in how memory usage is counted (affects only arm64/Graviton) and the fix was added in the v6.9 kernel version. Which makes 6.1 kernel used in AL2023 affected too.

Excess memory is not actually being consumed, so it's not a memory leak, though the bug is still fatal since the counter controls Linux's memory pressure logic.

You can check this Ubuntu bug timeline for more details.

Hi @nantiferov, This fix has been merged in 6.1.90-99.173.amzn2023 kernel, which is in the 2023.4.20230513 release. If you're up to date with AL2023 releases, this should be fixed.
