It appears that there -is- a public link where Linux ax.25 (and related) protocol stack bugfixes may be found - or some of them at least. You may
find those that Ralf Baechle submits at: https://marc.info/?a=102928398400004&r=1&w=4
This corrects a previous statement where I was under the impression that there was not such a site.
