kldxref: /boot/kernel/kernel: too many sections

Martin Laabs — 2012-05-26T11:41:05

Hello,

while updating my system I got the following error message while make 
installworld:

===> syscons/green (install)
install -o root -g wheel -m 555   green_saver.ko /boot/kernel
install -o root -g wheel -m 555   green_saver.ko.symbols /boot/kernel
kldxref /boot/kernel
kldxref: /boot/kernel/kernel: too many sections
kldxref: error while reading /boot/kernel/kernel: Bad address
su:/usr/src$

I tried to remove the /usr/obj and remake the kernel by make buildkernel 
again but the error remains.
I use 8.2-STABLE with a freshly updated RELENG_8 src.

I do not build all kernel modules so I have the following in my make.conf
MODULES_OVERRIDE = nfsserver linux linprocfs geom/geom_bde syscons/green

However - I don't think this explains the misbehavior of kldxref.

Can anybody give me a hint where to search for the bug?

Best regards,
  Martin Laabs

The underlying problem seems to be problems writing to /var/log.
Is the partition (/var probably) full up or out of inodes?

   df -ih /var/log

Also, look at the console to see if anything has been logged there.

If it isn't running out of space, then check that the directory hasn't
got weird flags settings:

   ls -laoR /var/log

Having something like noschg set on the directory would cause the
observed symptoms, but I am at a loss to understand how on earth
anything like that could come about.

There are a couple of other things it might be, but it's quite unlikely
you wouldn't get crashes, coredumps and other signs of the end-times
should any of those be the case.

Cheers,

Matthew

Dear list,
I have this issue with bzip2 and the generation of backup logfiles.
This is the error I get:

--- cut ---

bzip2: I/O or other error, bailing out.  Possible reason follows.
bzip2: No such file or directory
Input file = /var/log/all.log.0, output file = /var/log/all.log.0.bz2
newsyslog: `bzip2 -f /var/log/all.log.0' terminated with a non-zero 
status (1)
bzip2: Can't open input file /var/log/maillog.0: No such file or directory.
newsyslog: `bzip2 -f /var/log/maillog.0' terminated with a non-zero 
status (1)

--- cut ---

Can you tell me what goes wrong here and how to solve this?

thanks in advance,
Jos Chrispijn

Just serious now. I see you are frustrated, but it woul help if you gave

Re: ports tree

Thomas Mueller — 2012-05-26T08:58:40

from Henri Reinikainen <henrixd< at >gmail.com>:





What happens if the port a remote user is trying to build and install is updated in the middle of this remote activity?

Users of ports tree then must deal with a moving target.  Files from two different versions might get mixed together.

I think maybe this thread should go to ports< at >freebsd.org list?

Re: ports tree

Matthew Seaman — 2012-05-26T08:44:19

Not stupid, but certainly impracticable.  Remote mounting filesystems
over the internet is not going to be anything like scalable, and the
bandwidth requirements would be horrid.  As an end-user, performance
would suck -- inescapably, as you'ld be hit hard by latency.  Basically,
if you could afford the sort of network connectivity that would make
such a setup feasible, then you could easily afford sufficient local
storage that you wouldn't want to use a remote mount.

Also, forget the idea of *writing* to any such share disk space.  The
security problems with that just don't bear thinking about.

NFS mounting /usr/ports within a local network -- now, that's a
completely different kettle of fish.  You do need to tweak WRKDIRPREFIX
if you're going to have several systems building from the same tree
simultaneously, and it's probably going to be more effective for you to
use one machine as a central package build server and just install from
packages on your limited systems.

Cheers,

Matthew

ports tree

Henri Reinikainen — 2012-05-26T06:57:37

Hi

Would it be stupid idea to have publicly available, mountable (nfs)
partition, with full port tree(s)? I think it would be good for
systems with low storage space. I know hd space is cheap, but I run
over and over to this problem.

I don't know how easily it could be done, but some kind of session
based temporary write permissions would be good too. To be able to
make && make install directly from mounted partition.

I don't think very many people would need to have local personal copy
of ports tree then.

So, is this just stupid?

Re: why I am upset

Wojciech Puchar — 2012-05-26T06:11:20

so stop using trendy "desktop" and just start to do actual work and you 
will not be upset any more but happy.

"Desktop environments" offer exactly zero value and do nothing.
Just use fvwm2, maybe icewm, tune it to your needs and start working.
use xterm as your "start button" by starting program you need from command 
like. configure fvwm2 to have multiple "virtual desktop" switchable by 
keystrokes so you will have something like standard text console just in 
X11 with ability to run X11 programs.

in most cases - run one program on one virtual desktop. Multiple windows 
on screen is only fashionable but useless in practice.
After a while you will end in removing every unneeded things that are only 
fashionable but just wastes time and monitor space. For example window 
frames and titles.



"Desktop environments" are required so average winuser will not 
protest too much when i do X11 terminal based configuration.
but i use gnome2 this case with gdm as it is far faster (==less slow) than 
KDE, and as we

Re: Terminology: wheel

Robert Bonomi — 2012-05-26T03:58:57


There are numerous 'wheel' related terms in the 'casual English' lexicon.
See 'wheeler dealer', for example.

Those 'at the wheel' are those who are in charge -- in immediate control 
of steering the ship.

See also 'wheel horse'.  which has a secondary meaning of 'a diligent, 
dependble worker' -- one who can be trusted to 'do things right' (defined 
as 'the way the boss wants it done' :) 

Derived from a position in a team of horses used to pull wagons, coaches, 
etc. Some horses do *not* work well in a team at all, others are intractable
if they are not in a 'lead' position,

A 'wheel horse' will work behind others.   They will, _without_complaint_,
follow the "horse's ass" in the lead.   The parallel to computer operations
staff (the wheel group) is obvious.    *GRIN*

Re: Terminology: wheel

Jerome Herman — 2012-05-26T01:57:42

Legend as ti it was first used as a joke on Xerox system. There was a 
special bit that indicated that some operations could be accomplished, 
basically it was the ancestor of kernel space on old time sharing 
system, invented on TENEX. When it came to naming the bit it was turned 
into a pun : the bit wheel. The big wheel being a slang term meaning 
"powerful person in charge". So basically it was bit wheel for the 
powerful process in charge.

I do not know if it is accurate though, I wasn't at Xerox at the time 
and I never even saw a Tenex in all my life, but it seems the official 
explanation (at least the one all over the Internet). If someone can 
confirm/infirm...

Ah, thanks! I hoped there was a more... technical explaination
than just "wheel" being a slang term derivate. :-)

big wheel (idiomatic)
A person with a great deal of power or influence,
especially a high-ranking person in an organization.

slang "big wheel" -> wheel bit -> wheel group

Terminology: wheel

Polytropon — 2012-05-26T01:45:15

What inspiration (or maybe logical thought) is behind the
_naming_ of the "wheel" group?

I could find many explainations of what "wheel" is, what it
is for and how it is used (basic knowledge, I know), but I
couldn't find anything that states why this name has been
chosen. From other UNIX systems I know that there are groups
performing similar functions, but having different names
(such as "sysadmin" on Solaris prior to RBAC).

This question definitely shows my age. :-)

I should have mentioned that I did the (successful) test
logging in as root (real console login). If you use "su -"
or "su root", the effect should be the same. You can always
check the success of your operation with the "ls -lo" command.
