Change root.flp from a new format CPIO archive to a tar archive.
Unless we're willing to change the main tarballs from tar format to
"newc" (or, even better, "crc") cpio format, we need to use one common
one for all and that's tar for now. Install will now grab "root floppy"
from an ftp site if that's what you've got set.
Fix even more gripes from Poul's list.
P.S. As soon as I get the distfiles copied over to freefall tomorrow
morning, those of you wishing to test minimal installs over ftp should
be able to do so by grabbing the boot floppy and nothing else. Keep
your eyes open for my announcement.
Root floppy (which actually may be able to go completely away at some point
soon!) is now loadable from ftp/nfs/dos as well as CDROM and (of course)
floppy.
Fix more problems on Poul's Gripe List.
Rod, Jordan and David have more or less given me the OK on this
with the understanding that it doesn't change any functionality.
It doesn't: these are bug fixes only. No other part of the system
should be affected. Of course, since I'm the only one working on
NIS, you'll just have to take my word on it. :)
Fixes for the following annoyingly subtle bugs:
- ypbindproc_setdom_2 is supposed to be declared void *, not boot_t *,
and it fails to correctly signal failures back to the ypset(8) command:
we need to call one of the svcerr_*() functions (in this case,
svcerr_noprog() seems a logical choice -- we're really cheating
a bit here because nothing else quite fits) to tell ypset that the
attempt to set the binding for a domain failed. If we don't do this,
failed ypset attempts either appear (incorrectly) to succeed, or
they time out.
- The lock handling for child processes isn't quite right. The
child broadcaster processes have to release all locks on the
binding files and the ypbind.lock file.
- The parent ypbind process will SEGV if you do the following:
-- start ypbind with the -ypset or -ypsetme flag
-- type 'ypwhich -d random_unserved_domain'
-- type 'ypset -d random_unserved_domain anyhost'
-- type 'ypwhich -d random_unserved_domain' again
-- wait about 60 seconds
What happens is this: the ypwhich command causes ypbind to fork a
broadcaster process that searches for a server for random_unserved_domain.
If you then use ypset to force a binding while this process is still alive,
the state flags that tell the ypbind parent process that the child
is running will be cleared. The second ypwhich command then causes
a *second* child process to be forked for random_unserved_domain,
which is verbotten. When the first broadcaster exits and tells the
parent that it wasn't able to find a server for the domain, the parent
clobbers the entry for random_unserved_domain. Then the second broadcaster
exits and the same thing happens, only trying to clobber the entry
twice causes a SEGV.
The fix for this is a slight change in program structure: since we
can't have more than one broadcaster for a given domain at a time,
we save the pipe descriptors and pid for the child broadcaster in members
of the _dom_binding struct for the domain. (As a side effect, we
can get rid of the global child_fds variable.) So when rpc_received()
finds that it's been asked to do a ypset for a domain for which a
broadcaster process exists, it sends a SIGINT to the child to kill it
and closes the pipe to the now-dead child. This keeps everything in sync
and insures that we don't leak file descriptors.
- ping() should be using YPPROC_DOMAIN rather than YPPROC_DOMAIN_NONACK
when it does its clnt_call() to the server.
- Removed the check for client_handle == NULL in ping() and make
client_handle local to ping instead of a member of the _dom_binding
struct. This fixes another potential ypset problem: using ypset to
force a binding to a machine that has an NIS server but which *doesn't*
support the domain we're after can result in permanently bogus bindings.
- the 'server OK' message prints the wrong IP address.

- Make the child process reaper signal-driven. (Previously, we called reaper()
once a second each time we went through the select() loop. This was
convenient, but inefficient.)
- Increase main select() timeout from 1 second to 60 seconds and use
this as the ping timer instead of using timestamps in the _dom_binding
structure. This nd the reaper() change noted above makes ypbind a little
less CPU-intensive.
- Don't flag EINTR's from select() as errors since they will happen as a
result of incoming SIGCHLD's interrupting select().
- Prevent possible resource hogging. Currently we malloc() memory
each time a user process asks us to establish a binding for a domain,
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.)
- Changed "server not responding"/"server OK" messages to display server
IP addresses again since it looks spiffier.
- Use daemon() to daemonify ourselves,

- 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.
