once a second each time we went through the select() loop. This was
convenient, but inefficient.)

- Prevent possible resource hogging. Currently we malloc() memory

but we never free it. This could lead to serious memory leakage if a
'clever' user did something like ask ypwhich to check the bindings
for domains 0.0.0.0.0.0.0.0.0.0 through 9.9.9.9.9.9.9.9.9.9 inclusive.
(This would also make a mess out of the /var/yp/binding directory.)
We now avoid this silliness by a) limiting the maximum number of
simultaneous bindings we can manage to 200, and b) free()ing _dom_binding
structures of secondary domains whose servers have stopped responding.
We unlink the /var/yp/binding/domain.vers files for the free()ed
domains too.
(This is safe to do since a client can prod us into reestablishing the
binding, at which time we'll simply allocate a new _dom_binding structure
for it.)
We keep count of the total number of domains. If asked to
allocate more than the maximum, we return an error. I have yet to hear
of anybody needing 200 simultaneous NIS bindings, so this should be
enough. (I chose the number 200 arbitrarily. It can be increased if need
be.)

- Moved to a more client-driven model. We aggressively attempt to keep
the default domain bound (as before) but we give up on non-default
domains if we lose contact with a server and fail to get a response
after one round of broadcasting. This helps drastically reduce the
amount of network bandwitdh that ypbind consumes: if a client references
the secondary domain at some later point, this will prod ypbind into
establishing a new binding anyway, so continuously broadcasting without
need is pointless.
Note that we still actively seek out a binding for our default domain
even if no client program has queried us yet. I'm not exactly sure if
this matches SunOS's behavior or not, but I decided to do it this way
since we can get into all sorts of trouble if our default domain comes
unbound. Even so, we're still much quieter than we used to be.
- Removed a bunch of no-longer pertinent comments and a couple of
chunks of #ifdef 0'ed code that no longer fit in to the new layout.
- Theo deRaadt must have become frustrated with the callback mechanism
in clnt_broadcast(), because he shamelessly stole the clnt_broadcast()
code right out of the RPC library and hacked it up to suit his needs.
(Comments and all! :)
I can understand why: clnt_broadcast() blocks while awaiting replies.
Changing this behavior requires surgery. However, you can work around
this: fork the broadcast into a child process and relay the results
back to the parent via a pipe. (Careful obervation has shown that the
SunOS ypbind forks children for broadcasting too, though I can only
guess what sort of interprocess communication it uses. pipe() seems to
do the job well enough.)
This may seem like the long way around, but it's not really that
hard to implement, and I'd prefer to use documented RPC library functions
wherever possible. We're careful to limit the number of simultaneous
broadcasters to avoid swamping the system (the current limit is 5).
Each clnt_broadcast() call only sends out a small number of packets
at increasing intervals. We're also careful not to spawn more than one
bradcaster for a given domain.
- Used clntudp_bufcreate() and clnt_call() to implement a ping()
function for directly querying a particular server so that we can
check if it's still alive. This lets me completely remove the old
bradcasting code and use actual RPC library calls instead, at the
cost of more than a few handfulls of torn-out hair. (Make no mistake
folks: I *HATE* RPC.) Currently, the ping interval is one minute.
- Fixed another potential 'nfds too big for select()' bug: use
_rpc_dtablesize() instead of getdtablesize().
- Quieted gcc -Wall a bit.
- Probably a bunch of other stuff that I've forgotten.
ypbind.8:
- Updated man page to reflect modifications.
ypwhich.c:
- Small mind-o fix from last time: decode error results from
ypbind correctly (*groan*)
yplib.c:
- same as above
- Change behavior of _yp_dobind() a little: if we get back a 'Domain
not bound' error for a given domain, retry a few times before giving
up and passing the error back to the caller. We have to sleep for a
few seconds between tries since the 'Domain not bound' error comes
back immediately (by repeatedly looping, we end up pounding on ypbind).
We retry at most 20 times at 5 second intervals. This gives us a full
minute to get a response. This seems to deviate a bit from SunOS
behavior -- it appears to wait forever -- but I don't like the idea
of perpetually hanging inside a library call.
Note that this should fix the problems some people have with bindings
not being established fast enough at boot time; sometimes amd is started
in /etc/rc after ypbind has run but before it gets a binding set up. The
automounter gets annoyed at this and tends to exit. By pausing ther YP
calls until a binding is ready, we avoid this situation.
- Another _yp_dobind() change: if we determine that our binding files
are unlocked or nonexistent, jump directly to code that pokes ypbind
into restablishing the binding. Again, if it fails, we'll time out
eventually and return.

2. Add a "feature" to pkg_create (OK, OK, it's a miserable hack!) to get

ypbind.c: if a client program asks ypbind for the name of the server
for a particular domain, and there isn't a binding for that domain
available yet, ypbind needs to supply a status value along with its
failure message. Set yprespbody.ypbind_error before returning from
a ypbindproc_domain request.
yplib.c: properly handle the error status messages ypbind now has the
ability to send us. Add a ypbinderr_string() function to decode the
error values.

The first problem I found was that descriptor 0 was being closed.
This happens because the modem variable is set to 0 to indicate
that it is not valid but there are not enough tests for the modem
variable being 0. You can see where I have done this in the patch.
Code in OpenModem() dups the modem descriptor if it is < 3. Once
this happened the modem was always open and an incomming call would
have getty and ppp reading the modem.
Descriptor 1 is closed when the quit command was executed from a
telnet connection. The next modem open returns descriptor 1
and this gets duped leaving the modem always open again.
The modem was not being closed when the connection dropped or was
closed from the other end. The UUCP lock was also not removed if
the modem could not be opened.

one ypbind broadcast can yield several responses. This can lead to
some confusion: the syslog message from ypbind will indicate a rebinding
to the first server that responds, but we may subsequently change our
binding to another server when the other responses arrive. This results
in ypbind reporting 'server OK' to one address and ypwhich reporting a
binding to another.
The behavior of the rpc_received() function has been changed to prevent
this: subsequent responses received after a binding has already been
established are ignored. Rebinding gratuitously each time we get a
new response is silly anyway.
Also backed out the non-fix I made in my last ypbind commit. (Pass
me the extra large conical hat, please.)
(At some point I'm going to seriously re-work ypbind and the _yp_dobind()
library function to bring them in line with SunOS's documented behavior:
binding requests are supposed to be 'client-driven.' The _yp_dobind()
function should be responsible for retrying connections in response to
calls from client programs rather than having ypbind broadcasting
continously until a server responds. The current setup works okay in
normal operation, but we broadcast far too often than we should.)

1. pkg_create now has a -P argument for specifying dependencies on the
command line.
2. pkg_add will honor dependencies and chain-load them automatically if
it finds the required package(s) in the same directory as the package
that is being loaded. For best results, install packages from a directory
containing all the packages you'll possibly need
(like /usr/ports/packages/all).
2 remaining flaws:
1. pkg_add looks in one place (where you were when you loaded the primary
pkg) for depended packages. If you can come up with a search path scheme
that's not a total hack - be my guest!
2. Recursive dependency expansion can result in the name of a dep being
listed more than once. This doesn't bother pkg_add since it checks
for package existance with pkg_info and will skip already-loaded packages.

/some_file_system -ro host1 host1

When mountd sees this, it tries to put startide.ctr.columbia.edu into the

client issuing the rarp is expected to be in the middle of booting
and would therefore be unable to answer arp queries from other machines
on the wire. Having rarpd stuff a temporary entry for the booting
host into the local arp table helps keep arp requests from going unanswered.
Also added ether_print() and ether_ntoa() to the ether_addr.c module.
Eventually I'll get ether_aton() and ether_hostton() written and
then this file can be dropped straight into libc. (Assuming no one
objects, of course. :)
"Yes Virginia, there is a rarpd."
(Before anyone asks, this *not* the rarpd from NetBSD. It did come from
the same place as theirs, however.)
This is a port of the rarpd program included with the tcpdump-2.0
source code (which I finally unearthed after scrounging around
some of the darker corners of the Internet). It's as close to the
original as I could keep it except for the following changes:
- The original program was based on an older version of the Berkeley
Packet Filter which used different filter programming instructions.
Fortunately, an updated RARP packet filter is available right in the
BPF man page so this was easy to fix.
- The old code didn't know how to deal with variable length addresses
in ifreq buffers. This has been fixed.
- Some byte order weirdness had to be fixed. The sanity checks in
rarp_check() needed some htons()es, and the rarp_reply() function
needed to properly set the ether_type field in the ethernet header
to ETHERTYPE_REVARP before transmitting the packet, otherwise
the bytes in ether_type would wind up reversed. It is important to note
that using htons(ETHERTYPE_REVARP) will not work. This is odd, because
the NetBSD rarpd uses htons(ETHERTYPE_REVARP). (Praise be to tcpdump:
I would never have been able to track this silliness down without it.)
- The update_arptab() function has been castrated. It depends on
SIOCSARP which has been deprecated in 4.4BSD. The NetBSD people
don't seem to be using this function either. It wouldn't be too
hard to replace this with equivalent code from arp.c, but it
might not be necessary.
- I put together an ether_ntohost() support function that allows
both local (/etc/ethers) and NIS lookups. This stuff should go
in libc at some point, but nothing else seems to need it for now,
so it can wait a while.
As you may have guessed, you need to have the Berkeley Packet Filter in
your kernel in order to use this program. The good news is that together
with the recently added bootparamd, you can use finally use a FreeBSD
box to boot Sun boxes over the network. (This was my whole motivation
for getting this stuff to work: I have this one subnet that has a whole
bunch of Sun3 X-terminals on it with only two Sun4 workstations, both
of which are locked in peoples' offices. If those two machines crash
(and they do every so often) then none of the X-terms will boot. Now I
can use a spare PC that I have as a boot server. :)
thinking that it would work :( The install program never get a destination
directory. Here is another patch that should also be added. I think this
should be the last one for these makefiles :)
[Note: I realize that there are more things wrong than this, but this should
at least get the tree compiling again! -jkh]
