Hi Greg, hi Sasha,

Could you please queue up

eaaff9b6702e ("netfilter: fib: avoid lookup if socket is available")

for 6.14 and 6.12?

Unfortunately I did not realize that the missing handling of
'input' is not just a missing optimization but an actual bug fix, else
I would have split this patch in two.

The bug exists since 5.19, but its not a regression ('never worked').

Given noone noticed/reported this until this week
(https://lore.kernel.org/netfilter/20250422114352.GA2092@breakpoint.cc/),
we think it makes sense to only apply this to the two most recent trees
and keep the rest as-is, users of those trees evidently don't use the
b0rken configuration or they would have complained long ago.

The commit cherry-picks cleanly to both.
If you disagree let me know, I could also make a stable-only patch that
only contains the bug fix part of the mentioned commit.

Thanks!
