needed to make the asynchronous DNS lookup mechanism work. (It needs to
be able to get/set the transaction ID in the trasport handle so it can
deliver a delayed UDP response when a reply is received from a DNS
server.) With TI-TPC, the transport handle has changed slightly (what
used to be an int is now a size_t) so we need to account for this.
associated changes that had to happen to make this possible as well as
bugs fixed along the way.
Bring in required TLI library routines to support this.
Since we don't support TLI we've essentially copied what NetBSD
has done, adding a thin layer to emulate direct the TLI calls
into BSD socket calls.
This is mostly from Sun's tirpc release that was made in 1994,
however some fixes were backported from the 1999 release (supposedly
only made available after this porting effort was underway).
The submitter has agreed to continue on and bring us up to the
1999 release.
Several key features are introduced with this update:
Client calls are thread safe. (1999 code has server side thread
safe)
Updated, a more modern interface.
Many userland updates were done to bring the code up to par with
the recent RPC API.
There is an update to the pthreads library, a function
pthread_main_np() was added to emulate a function of Sun's threads
library.
While we're at it, bring in NetBSD's lockd, it's been far too
long of a wait.
New rpcbind(8) replaces portmap(8) (supporting communication over
an authenticated Unix-domain socket, and by default only allowing
set and unset requests over that channel). It's much more secure
than the old portmapper.
Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
to support TI-RPC and to support IPV6.
Umount(8) is also fixed to unmount pathnames longer than 80 chars,
which are currently truncated by the Kernel statfs structure.

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.

in source input if the -f flag is used, and modify Makefile.yp to only
use -f for the passwd, master.passwd and group maps. These should be
the only ones for which the + and - characters have special meaning
that make it important for us to avoid letting them into any of the map
databases. In some cases (namely the automounter maps) we have to allow
at least the - character through in order to create the map properly.
This closes PR #8699.

This really fixes the condition where a child creates children of its own.
I'm leaving the previous sanity tests in though, since they shouldn't hurt,
and will give an indication if this ever happens again.
try to fork() a child of its own, which could result in several children
ypservs running at once. I'm still not sure exactly what leads to this
condition, but these fixes should stop it from causing trouble. A new
function, yp_fork() checks to see if the current process is already a
child of the parent ypserv, and returns failure (and logs an error message)
rather than spawning another child.
Under certain conditions (possibly associated with heavy load), ypserv will
fork() child processes that don't exit like they're supposed to. I think
this is because of some suspect logic in the ypproc_all procedure. I updated
it to use what I hope is a more bulletproof approach.
Also tweaked yp_svc_run() a little so that the 'are we a child?' test happens
at every pass through the for(;;) loop, not just immediately after returning
from svc_getreqset2().
to be clever by avoiding the 'check all domains in the search list'
cycle in certain cases, but this would lose if handed a name like
"foo.ctr" which refers to an FQDN of "foo.ctr.columbia.edu". If
"columbia.edu" is in the search list in /etc/resolv.conf then the
DNS lookup code should resolve it, but it didn't.
(a.k.a. /var/yp/Makefile.dist) refers to an obsoleted usage of the
-m option of rpc.yppasswdd. It is currently taken over by the -t
option. -m is used for a different purpose now.

/etc/services entries with any protocol instead of just udp and tcp.
Rather thani having the awk script explicitly search for 'udp' or 'tcp'
in the second field using index(), use split() to break up the field
at the '/' character if it exists, which extracts the protocol from
the field no matter what it is.

underlying database code works. When dealing with first/next queries, you
have the notion of a database 'cursor,' which is essentially a file pointer
for the database. To select the first entry, you do a fetch with the
R_FIRST flag set, then you can use the R_NEXT flag to enumerate the other
entries in the database. Unfortunately, doing a direct fetch with no flag
does _not_ set the 'cursor,' so you can't do a direct fetch and then
enumerate the table from there.
The bug is that cached handles generated as the result of a YPPROC_MATCH
were being treated as though they were the same as handles generated by
a YPPROC_FIRST, which is not the case. The manifestation is that if you
do a 'ypmatch first-key-in-map map' followed by a yp_first()/yp_next()
pair, the yp_first() and yp_next() both return the first key in the
table, which makes the entry appear to be duplicated.
A couple smaller things since I'm here:
- yp_main.c and yp_error.c both have a global 'int debug' in them.
For some reason, our cc/ld doesn't flag this as a multiply defined
symbol even though it should. Removed the declaration from yp_main.c;
we want the one in yp_error.c.
- The Makefile wasn't installing ypinit in the right place.
/tmp/ypmake, thereby fixing problems with successive map updates
possibly reading stale copies of this file left behind by a previous
failed run.
