(In reply to Martin Birgmeier from comment #5)
Thanks for testing. ypxfr_getmap.c is only compiled into ypxfr and yppush, so
you shouldn't need to recompile anything else.

That did the trick, thanks.

I ran make in libexec/ypxfr and usr.sbin/yppush; any other binaries that would
be affected by the change?

Created attachment 175798
  --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=175798=edit
proposed patch

This looks like a regression from r285926: ypxfr_getmap.c references a couple
of libc symbols, and that revision turned them into local symbols. Could you
try the attached patch?

Could you obtain backtraces from the ypxfr and yppush cores and paste them in
this PR?

[Bug 213506] YP/NIS: yppush, ypxfr dump core

2016-10-15 Thread bugzilla-noreply 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213506

Bug ID: 213506
   Summary: YP/NIS: yppush, ypxfr dump core
   Product: Base System
   Version: 11.0-STABLE
  Hardware: Any
OS: Any
Status: New
  Severity: Affects Only Me
  Priority: ---
 Component: bin
  Assignee: freebsd-bugs@FreeBSD.org
  Reporter: la5lb...@aon.at

I have a YP (NIS) setup with one master server and several slave servers. One
of the latter is in ypservers (together with the master server, as setup by
ypinit -m).

If I modify a YP-relevant file on the master server and do a 'make' in /var/yp,
yppush fails with a segmentation violation (signal 11) and dumps core. This
aborts 'make', thereby not processing the remaining maps.

If I manually ypxfr a map from the master to any of the slave servers (invoked
at the respective slave server as "ypxfr -h  "), ypxfr
fails with a segmentation violation (signal 11) and dumps core. It leaves a
zero-sized file in /var/yp/ with a . suffix, e.g.,
rpc.byname.4631.

None of this happened with 10.3.

Btw, the only maps which can be successfully transferred are empty ones, i.e.,
containing no entries. The associated file in /var/yp/ has a size
of 40960 bytes.

One more note: this started to happen several months ago on 11-current compiled
for armv6. At that time I thought it was just a problem on that architecture.
But now, after installing 11.0 on all my machines, it happens on all of them
(amd64 and i386).
