Results (kfreebsd-amd64 @ KVM): Without your patch the following gets logged (note that the errno seems to be different from what Emanuele and me get with the Debian packaged 8.4.7 version, but in both cases the identification fails): LOG: could not get peer credentials: No such file or directory FATAL: Ident authentication failed for user "itsme" [ Warning: I manually copied (typed) this from a KVM console. ] While with your patch nothing gets logged, the identification just works.
