This program does what the old one did, PLUS:
- Supports parallel jobs (like the SunOS yppush)
- Does everything in one proces instead of fork()ing off
children processes as callback listeners (this is done
using async socket I/O).
- Can be used to transmit maps to user-specified hosts.
- Has a much more verbose verbose option.
- Reuses existing code from ypserv and ypxfr.
- Uses some rpcgen-erated code as well.
- Isn't fattening. :)
Note that this is going in /usr/sbin rather than /usr/bin like
the old one. yppush is an administrative command it it's anything.
SPIORDY just before we ack on the bus so that there is no chance to
see SPIORDY for the same byte twice.
Make some small modifications so that the Linux aic7xxx driver can use
our sequencer and register definition files verbatum.
on a failure, but if we're checking a corrupt map we could also get back
a zero from ypserv without really encountering any actual error. Flag this
condition and generate an meaningful error message.
- Fix transmission of ypxfr_clear to ypserv: error checking was wrong
and we sending YPXFR_YPERR as an error status instead of YPXFR_CLEAR.
- To help avoid a race condition (or at least reduce the likelyhood of
it occuring), use rename() to move a newly transfered map into place
instead of unlink()ing the old one first and then renaming. Da man page
sez that rename should do the unlink() for us. This prevents ypserv
from returning 'no such map in domain' when asked to query a map which
ypxfr has just unlink()ed but not yet replaced.
In yp_server.c:
- Modify ypproc_xfr_2_svc() so that it sends both a return status and
a yppush callback (if necessary: normally ypxfr is supposed to send the
callback once it's done transfering a map, but if we can't get ypxfr
off the ground for some reason, we have to send it here instead) and
do it in the right order: have to send the reply to the ypproc_xfr
request first, then send callback. This requires us to cheat a bit:
you're supposed to just return() and let the RPC dispatcher send
the reply for you, but we wouldn't be able to send the callback message
if we did that, so we have to call svc_sendreply() ourselves, then
send the callback, and then return NULL so that the RPC dispatcher
won't call svc_sendreply() itself.
- Also modify ypproc_xfr_2_svc() so that it doesn't invoke ypxfr with
the -f flag: this overrides the order number checks, which prevents
us from ever refusing maps that aren't newer than then ones we already
have.
In yp_access.c:
- Fix a typo in the TCP_WRAPPER support code (which is #ifdef'ed out
by default): a close paren somehow vanished into the ether.
(To be replaced by sysctl accesses some time ...)
Remove a backward jump from the NCR script, which allowed a SCSI target
to receive any number of NOP messages it desired. If a target indeed
does such a silly thing, make it fail at the next instruction, instead
of causing a timeout a few seconds later.
added "#define PRECISE_SYMLINKS" to the amd config header - this
solves a problem with the amd "-type:=direct" mounts and /bin/sh
giving a "readlink failed" if you cd'ed to a "-type:=direct" mounted
directory
i got this from david mazieres as a result of giving him our (mostly
doug rabsons) fixes for the amd "-type:=direct" mounts and telling
them (also some NetBSD people were interested) about my only problem
running these fixes (which is now solved too :-)
it out fixes my problem but hoses the GUS MAX probe messages. Check what
device we have and print things appropriately for each.

local address, that was assigned with ifconfig alias and netmask
0xffffffff, would receive duplictae udp packets.
This behaviour can easily be seen by having named run, and using the alias
address as the name server.
This solution is not the pretiest one, but after talk with Garreth, it
is seen as the most easy one.
variants, idea taken from NetBSD clock.c.
At least year calculation was wrong, pointed by Bruce.
Use different strategy to store year for BIOS without RTC_CENTURY
