MFC: Remove padding for ABI compatibility of ai_addrlen member

2005-07-22T20:17:30+00:00

from struct addrinfo.  This change break ABI compatibility on
64 bit arch.

- The ai_addrlen of a struct addrinfo used to be a size_t, per

2005-05-15T20:15:15+00:00

  RFC 2553.  In XNS5.2, and subsequently in POSIX-2001 and RFC
  3493, it was changed to a socklen_t.  And, the n_net of a
  struct netent used to be an unsigned long integer.  In XNS5,
  and subsequently in POSIX-2001, it was changed to an uint32_t.
  To accomodate for this while preserving ABI compatibility with
  the old interface, we need to prepend or append 32 bits of
  padding, depending on the (LP64) architecture's endianness.
- Correct 1st argument of getnetbyaddr() to uint32_t on 32
  bit arch.  Stay as is on 64 bit arch for ABI backward
  compatibility for now.

Fix the matchlen() function so that it handles the IPv4 (AF_INET)
case correctly.  Until now it has been treating IPv4 addresses
as if they were IPv6 which could lead to corruption errors.

free ypbuf only when yp_match() succeed.

the 3rd argument of getsockname() should be socklen_t*.

Now, our getservbyname(3) is thread-safe. So, we don't need

2005-04-15T18:15:12+00:00

to protect it with mutex lock.

hostalias() is not thread-safe. So, introduce _res_hostalias()

2005-04-15T14:42:29+00:00

and use it.
