https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/netinet_in.h.html in POSIX only has IPV6_JOIN_GROUP/IPV6_LEAVE_GROUP . To me it looks like Rust is using a non-standard name for the constant, and that should be fixed on Rust side?

It's not really the Rust side, it is the net2 crate and it seems that by default it goes to the Linuxism (?) of IPV6_ADD_MEMBERSHIP. I have submitted a PR to fix the net2 crate on Haiku.
Closing this enhancement as it is not necessary.

The definitions are missing, but are they really?
There are some sources that seem to imply that they are the same.
I am just wondering whether we should add them as aliases in posix/netinet/in.h as part of the official API, or whether we just define them as aliases in Rust's libc?
