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.

I changed to close to original code before merging IPv6 support.
It seems having delay before another try is useless. However, I'm
not sure that delay means. So, I leave it as-is.

strdup()) rather than pointing it at something that's free()d
(via freeaddrinfo(res)) before the function returns.
I appreciate that this is an API change, but it's the only way
(AFAIK) of doing this without breaking existing code that uses
rcmd{,_af}().

management involving rcmd_af(), getaddrinfo(), freeaddrinfo(), etc.
We set *ahost to point to ai->canonname; and later free the ai-> stuff
and still leave the old pointers in *ahost to the freed data.
Perhaps the best way to deal with this is a static buffer or a static
strdup() that is freed on the next iteration or something. This gives
me headaches just thinking about this.
The new 'AJ' default for malloc() tripped this up.

when parsing certain DNS records during a reverse address resolution. Thus
when code tries to examine the returned host name, it dereferences a null
pointer :-(
Problem noticed by: ps
getaddrinfo() accidentally returns IPv4 mapped IPv6 address instead
of native IPv4 address.
Now, getaddinfo() is scoped address ready. You can put scoped
address within /etc/hosts.

being scheduled at a more frequent interval than the poll timeout.

Sorry for the flapping, but no change will be done for 4.0 anymore.
Official standard will be published around April or later.
If different format would be adopted at that time, then support for
the new format will be added to the succeeding FreeBSD 4.x.

data available, which is also wrong but is better than dumping core.
