Hi Sasha,
This patch cannot be applied to upstream, the code is significantly different. Therefore, this un-do patch would not be seen in the upstream git log. It was solved there by coding a better solution, not by the un-do patch.
Okay, so this is effectively a request to diverge the -stable tree from upstream in a non-trivial way, which is why I asked David Miller to ack this act explcitly (or to send me patches, or whatever else he thinks is appropriate here).
Please consider this: Upstream passes the TAHI IPv6 protocol tests. All the LTS kernels do NOT. This is the patch that causes the failure in 4.9, 4.14, 4.19 LTS kernels.
I very much agree that this should get fixed. My concerns are not with the bug but are with the proposed fix as it applies to -stable trees.
And this patch has been in place with 4.9.134, a long time. It is not right that "Linux" can not pass the IPv6 protocol test. My executive are asking me why "Linux" is not fit for IPv6 deployments.
Arguments such as this carry no weight in a more technical discussion such as this. Yes, some tests are currently broken, but we will not take shortcuts just because "executives are unhappy".
