>Description:
In the implementation of getnameinfo():
if (sa->sa_len != salen)
return EAI_FAIL;
This requirement of manually set sa->sa_len is unnecessary since POSIX does not require such a field in sockaddr, and it causes trouble for programs ported from OSs such as Linux where there is no sa_len field at all.
