There was some personal tragedy involved. The resolution for this is being tracked at: https://reviews.freebsd.org/D5= 5031 With a minor errno correction at: https://reviews.freebsd.org/D55233 TL;DR This is purely an optional extension. It is not and never was a bug. = The OpenJDK and other software started relying on it over the years, but it rea= lly doesn't fit with how the socket APIs involved were intended to operate, at = all. It largely stems from uncertainty about the extent of IPv4-mapped address support, as tuexen has indicated. The cheap fix is to just do what Apple did and just pass it through to neti= net for simple ASM-mode adds/joins, which is the most common multicast use case anyway, and it's usually for local link scoped groups. --=20 You are receiving this mail because: You are on the CC list for the bug.=
