The size of Unix pathname addresses is computed in selftests using offsetof(struct sockaddr_un, sun_path) + strlen(xxx). It should have been that +1, which makes addresses passed to the libc and kernel non-NULL-terminated. unix_mkname_bsd() fixes that in Linux so there is no harm, but just using sizeof(the address struct) should improve readability.
