ld: kernel.debug: Not enough room for program headers (allocated 5, need 6)

Thu Nov 17 14:54:13 UTC 2011

Color me perplexed.

3 of the 4 kernels I build were fine; the 4th one ... ugh.

I'm tracking stable/8 daily & rebuild as often as that (less if there
are no changes).  I do this on 2 machines: my laptop (which only builds
for itself) and a "build machine" (named "freebeast"), which builds
GENERIC for itself, as well as kernels ALBERT & JANUS for a couple of
other machines.

The laptop was fine (for stable/8); it was running:

FreeBSD g1-227.catwhisker.org 8.2-STABLE FreeBSD 8.2-STABLE #272 r227447M: Fri Nov 11 04:07:05 PST 2011     root at g1-227.catwhisker.org:/common/S1/obj/usr/src/sys/CANARY  i386

and is now running:

FreeBSD g1-227.catwhisker.org 8.2-STABLE FreeBSD 8.2-STABLE #273 r227611M: Thu Nov 17 04:16:50 PST 2011     root at g1-227.catwhisker.org:/common/S1/obj/usr/src/sys/CANARY  i386

(The "M" suffix on the GRN is for a patch to sys/conf/newvers.sh
so it will recognize my working copy as SVN even though there is
no sys/.svn directory, since I'm using subversion-1.7.1.)

The build machine is running:

FreeBSD freebeast.catwhisker.org 8.2-STABLE FreeBSD 8.2-STABLE #400 r227447M: Fri Nov 11 04:11:35 PST 2011     root at freebeast.catwhisker.org:/common/S1/obj/usr/src/sys/GENERIC  i386

it rebuilt GENERIC & ALBERT OK, then on JANUS, the "make buildkernel"
terminated with:

freebeast(8.2-S)[3] 

I'm rather left wondering "room" where, precisely?

The other perplexing thing is that JANUS is actually a subset of
my laptop's kernel config, and it's been getting built routinely;
as of its most recent update, it is running:

FreeBSD janus.catwhisker.org 8.2-STABLE FreeBSD 8.2-STABLE #398 r227447M: Fri Nov 11 04:15:30 PST 2011     root at freebeast.catwhisker.org:/common/S1/obj/usr/src/sys/JANUS  i386

And I've not changed the JANUS config since date: 2010/04/18 13:04:27;
author: david;  state: Exp;

Here's a copy:

#
# JANUS -- kernel configuration file for FreeBSD/i386 as a packet filter
#

include GENERIC

# firewall support, for access limiting

options 	IPFIREWALL
# options 	IPFIREWALL_DEFAULT_TO_ACCEPT
options 	IPFIREWALL_VERBOSE	#enable logging to syslogd(8)
options 	IPFIREWALL_VERBOSE_LIMIT=0	#do not limit verbosity

# dummynet for bandwidth limiting (requires IPFIREWALL)

options DUMMYNET

# divert sockets for natd

options IPDIVERT

[End of JANUS config]

As noted, since my laptop is also exposed to networks I don't
control, its kernel is also built with the above options (as well
as quite a few more, for support of user-interface, vs. headless
server, operation).  And it built & runs fine....

Clues?

Thanks!

Peace,
david
