There's a bogus implementation of gethostbyaddr_r() in lib/libc/net/gethostnamadr.c that was committed 6 years and nine months ago:
/*
* Temporary function (not thread safe)
*/
int gethostbyaddr_r(const char *addr, int len, int type,
struct hostent *result, struct hostent_data *buffer)
{
struct hostent *hp;
int ret;
if ((hp = gethostbyaddr(addr, len, type)) == NULL) {
ret = -1;
} else {
memcpy(result, hp, sizeof(struct hostent));
ret = 0;
}
return(ret);
}
What's the deal here? Despite the fact that this is not prototyped in
a header, some ports are detecting this, and -- one assumes -- not
behaving correctly since this implementation isn't thread-safe.
