netent.
- Change 1st argument of getnetbyaddr() to an uint32_t on 64 bit
arch as well to confirm to POSIX-2001.
These changes break ABI compatibility on 64 bit arch.
There is similar padding issue for ai_addrlen of struct addrinfo.
However, it is leaved as is for now.

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.

configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.
= Hesiod has been added to libc (see hesiod(3)).
= A library routine for parsing nsswitch.conf and invoking callback
functions as specified has been added to libc (see nsdispatch(3)).
= The following C library functions have been modified to use nsdispatch:
. getgrent, getgrnam, getgrgid
. getpwent, getpwnam, getpwuid
. getusershell
. getaddrinfo
. gethostbyname, gethostbyname2, gethostbyaddr
. getnetbyname, getnetbyaddr
. getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr
= host.conf has been removed from src/etc. rc.network has been modified
to warn that host.conf is no longer used at boot time. In addition, if
there is a host.conf but no nsswitch.conf, the latter is created at boot
time from the former.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- getservent:
o put _yp_check() proto under #ifdef YP where it belongs
o local YP buffers should be YPMAXRECORD + 2 bytes long and should
be NUL terminated after copying
- gethostbynis:
o local YP buffer should be YPMAXRECORD + 2 bytes long
- getnetbynis:
o local YP buffer should be YPMAXRECORD + 2 bytes long and should
be NUL terminated after copying
- ether_addr:
o local YP buffers should be YPMAXRECORD + 2 bytes long and should
be NUL terminated after copying (in this case it's BUFSIZ + 2 bytes,
but it happens that BUFSIZ == YPMAXRECORD.
- gethostbydns:
o nuke stray 'return(NULL)' in __dns_getanswer() (harmless but looks silly)
These are 2.2 candidates. I will wait a few days to make sure these don't
break anything and then, if there are no objections, move them to the 2.2
branch.
and he said:
The 3rd agrument is new; looks like it was part of the upgrade to
a new BIND with some IPv6 support. The third argument here should be
AF_INET. In order for it to be anything else, I'd have to add new
NIS functions to support IPv6 lookups. I don't even know what those
look like yet.
So there ya go, add AF_INET as the 3rd argument to the call.

broken. The translation from network number to ASCII string was not
working correctly (you would sometimes get things like 0.244.0.0 instead
of 244.0.0).
Also copied results of yp_match() to a static buffer for consistency
with gethostbynis.c.
Note: _getnetbynisaddr() chops off trailing .0's, i.e. 244.0.0 is
truncated to 244. By contrast, getnetbyht.c code (for local /etc/networks
lookups) leaves the traling .0's in place. This means that the NIS
and local file lookups will match different things when looking up the
same network number. I'm not sure which is the correct behavior. (I
think the DNS lookup code tries all combinations -- should the NIS
and local host lookup routines do that too?)
