--- Comment #39 from Franco Fichtner <franco@opnsense.org> ---
The evidence is the original SA patch series which spans hundreds of lines =
of
code changes and a lack of actual test coverage. The lack of benefit of dou=
bt
is strange in my opinion.

I can revert only these patches and the problem disappears. Do you want to =
know
which exact commit is responsible? I can offer you this information.

The further evidence is that pfctl -d fixes missing ND responses immediatel=
y on
affected systems.

You wouldn't see these issues unless you used pf heavily coupled with IPv6
connectivity.  These things are not prevalent in FreeBSD users, but they wi=
ll
certainly manifest in pfSense quite soon as well.  I can see that with other
patch submissions I have done over the past few weeks for FreeBSD 14.1 none=
 of
which have been wilfully been looked at by the relevant authors of bugs in
FreeBSD 14.0 and 14.1. I guess we can continue this hide and seek, but I wo=
uld
rather have it that we work together to fix issues within FreeBSD production
releases together?


Cheers,
Franco
