[Bug 297220] infinite recursion in pfi_kkif_update()

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D297220

--- Comment #1 from Kristof Provost <[email protected]> ---
The root problem here is arguably not in pf but in the network stack interf=
ace
rename code.=20
Pf assumes that network groups and network interfaces share a namespace. Th=
is
used to be true, but the assumption was broken when renaming interfaces was
introduced.=20
That=E2=80=99s what causes the confusion here, and the panic.=20
I thought I=E2=80=99d hacked it up enough to at least avoid the panic, but =
clearly
there are still broken scenarios.=20

I=E2=80=99ll see if I can at least avoid the panic, but realistically the b=
ehaviour
will still be buggy until the network stack itself is fixed.=20

(There are other bug reports about this, but I don=E2=80=99t have the numbe=
rs at hand.)
