- 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.
seperate exit values depending on the error. (The error values are
#defined and commented near the top of the file for clarity). This
is to help write a small bit of shell script for /etc/rc that calls
ypwhich a few times after ypbind is invoked to make sure we're
actually bound to a server before proceeding (if we aren't, the
automounter can fail if it's using NIS maps).
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.
ypwhich.c: handle ypbind errors correctly: yperr_string() can't handle
ypbind_status messages -- use ypbinderr_string instead.
some (hopefully) less offensive stupidity:
If we detect that a user has loaded a module that fails to initialize
itself correctly, panic. There really isn't a safe way to recover from
something like this; we can't know that the module is bad until after
the entry point is called, by which time it's too late to do anything
about it.

the symlinks for yppasswd & friends (we still can't use hard links
because passwd is installed immutable). This would have been simpler
if the LN_FLAGS variable hadn't chosen to wait until now before leaping
out of the /usr/share/mk directory and biting me in the ass. (And thus,
I was enlightened.)

This is consistent with gnu sed, SunOS, Ultrix (and probably others!)
of hard links: since passwd is installed immutable, an attempt to make
a hard link to it during a 'make install' would fail. I didn't notice
this conflict because my /usr directory is an NFS filesystem mounted from a
SunOS server, so the special file mode flags had no effecti when I tested
everything on my machine. Live and learn.
This is the first round of changes to incorporate YP server functionality
into FreeBSD. This particular change allows passwd to change either the
local or NIS password, as well as the NIS GECOS and shell information.
Essentially, I've taken passwd(1) and yppasswd from the yppasswd-0.5
distribution (which is part of the NYS project -- a project to provide
a GNU GPL'ed suite of NIS tools) and rammed them into each other
at high speed. I've tried my best to make this co-exist with the
Kerberos stuff, but since I don't run Kerberos I don't have an easy
way to verify that it all works. If you choose any Kerberos flags
then the YP checks should be bypassed, but that may not be enough.
I'll modify it some more if it turns out I broke something. For now,
support for localand NIS passwords is pretty solid:
- If you simply type 'passwd,' the program checks to see if you exist
in the local pwd.db database. If not, you get bounced to YP.
- If you try to force local functionality with the -l flag and you
don't exist locally, you get an error.
The -y flag can be used to force YP functionality. -f and -s let you
change your full name and shell (respectively). -f *and* -s let you
change all of your 'account information.'
ypchfn, ypchsh, yppasswd and ypchpass are all links to passwd.
It will read a file on stdin and write it as decimal integers on stdout,
this is useful for embedding files in c-sources.
There are a few places where this is needed, and this is a better way than
the current practice of hand-editing the sources.
The command:
date | file2c 'const char date[] = {' ',0};'
will produce:
const char date[] = {
83,97,116,32,74,97,110,32,50,56,32,49,54,58,52,55,58,51,51,32,80,83,84,
32,49,57,57,53,10

to be padded to 8 chars. Simply make sure that never more than 8 chars
are printed ( %-.8s ). The former commit otherwise hosed the width
calculation and landed on different positions for the time output.
Also the strlen(xx_out_line) hoses the wide

Simply use always 8 chars for the out_line calculation now. Looks good
this way.

sigjmp_buf's yet. Fixed the tips to reflect the new archive site.

that give back invalid port numbers to PASV.
v1.8.8 - December 19, 1994. Now falls back to port FTP if passive FTP fails.
