Subject: "kernel: khm" error
Date: 27 May 1999 08:39:05 GMT
Hi,
I have previously posted the smae question but got no answer... I try
again!
I am under X, in an xterm. I su to root, then ask for another xterm. The
command hangs. On the console I see:
[date]: [hostname] kernel: khm
As far as I see, I get the same behaviour (command hang+console message)
for all programs that need to open a window (e.g. emacs, fr and others).
They all hang. No problem if I don't need any window (e.g. emacs -nw).
But I also seem to have problem with other processes that run as root.
E.g., I cannot connect to my httpd server... the connection hangs although
the server is running, same kernel: khm error on the console.
I have a custom 2.2.3 kernel on a redhat 5.2 installation. I have this
kernel since the end of March and never had this problem before today.
I would really appreaciate some help!
thanks,
Stefano

Ah, yes! Thanks for the reminder. It's been a while since I read the

a reference to other relevant pages including the other crontab page.

Date: Thu, 27 May 1999 11:46:46 +0200
Hi all,
I wish to upgrade my 2.0.36 kernel to the 2.2.9 kernel.
The problem is that my machine got an IP alias (it have ifcfg-eth0
and ifcfg-eth0:0) and the 2.2.9 kernel doesn't have the
CONFIG_NET_ALIAS option in the kernel configuration. It only
have CONFIG_IP_ALIAS but it doesn't seem to be enougth.
Can someone tell me how to keep my alias even with this kernel ?
I tried to launch ifup-aliases eth0:0 but it didn't work.
Maybe a script need to be modified but wich one and how ?
Thanks

I hate to pull a proof by intimidation here, but the best answer to
your question is "because Linus said so." To quote from the COPYING
file in the Linux source code distribution:
NOTE! This copyright [GNU] does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
So he explicitly releases programs that make system calls from the
requirements of the GPL. He has also allowed kernel modules to be
distributed sans source as well, as long as the modules do not require
modifications to the kernel itself. And since Linus and kernel
contributors who presumably agree with his interpretation own the
copyright to the Linux kernel, it is not up to you or me to say that
the Linux license doesn't allow this software or that to be run under
Linux.
You might feel this is dumb, but I think this is internally consistent.

Fine.

The reason you made this statement in the first place, I think, is
because the Linux kernel doesn't infect the programs it runs with
GPL. As I mentioned above, Linus has explicitly granted users immunity
from that nonsense, so this part of the argument is now specious.
No matter what you do to a GPL'ed source, it stays GPL. You cannot ever
make it LGPL without convincing the copyright holders to do it for you.

No.

OTOH, a wrapper does not give you nearly as much flexibility as a
library call or tweaking the original source code. It merely lets
you use the program in the same way you would have if it were closed
source to begin with.

Yes. If this is what interests you, go ahead. Sun has been using
XEmacs as part of its developer suite (definitely not open source) for
some time. Netscape Communicator for Unix is distributed with GNU
movemail, but it doesn't provide anything under GPL except for
movemail itself. Metrowerks is working on an (presumably
closed-source) IDE for Linux with gcc as its back end. There is a free
IDE called Code Crusader and Code Medic which uses gcc and gdb as
back ends. Their sources are freely available, but they cannot be GPL'ed
because they depend on a closed-source widgets library (xforms).
These are just off the top of my head; I'm sure there are many other
examples of non-GPL'ed wrappers around GPL'ed software.
>Game over man.
Not so fast.
I don't see why you are so worked up over wrappers. Closed-source
vendors using wrappers around open-source software aren't taking any
more advantage of open-source software than open-source software that
are wrappers around closed-source software take advantage of the
closed-source software. Any GPL'ed Java application that is run on
Sun's JVM fall under this category. Running GNU bash on Solaris and
typing 'ls' in it would qualify, too. So far I haven't heard any
argument from Sun that either of these actions would put the user
applications under whatever licenses Sun would like.
It is worth pointing out that people have been writing non-GPL'ed
wrappers around GPL'ed software for ages. The last time I checked,
GPL'ed software is hardly in a "game over" state.
>> A wrapper can not behave like a library.
>
>Yes it can.
Here is a challenge: wrap up GNU readline so that it can be used from
arbitrary proprietary programs. If you can get it to work, some people
might be interested in it, as (AFAIK) there really isn't any good
non-GNU alternative to readline. I don't doubt it is possible, but I
don't think it will be particularly simple, efficient, or feature-
complete either.

rmdir(1) itself is little more than a simple wrapper for rmdir(2) with
a small option parser. So no, a wrapper for the GPL'ed rmdir binary
is not very different from making the rmdir() call from your program.
OTOH, you didn't save yourself very much work, and you did lose
performance with the extra fork-and-wait burden, which is probably
insignificant in this case.
For more complex programs, the difference may become more
obvious. Let's say you are writing some sort of program that needs an
embedded command line and a script parser, and you decide to use bash
for this purpose. If you are willing to GPL your program, you just rip
apart bash's source code, embed it into your oown program, and maybe
add a few internal commands for your purposes. If you want to thumb
your nose at RMS by using wrappers, well, good luck. You might get
something usable out of it, but it certainly won't win you any awards
in the performance department.

There is no (ix86) checksum.c file in the 2.2 kernel series.
It must be left over from some old kernel source. Delete it.
(The 2.2.5 kernel has been out of date for about 1.5 months now.
Try 2.2.7 or 2.2.9.)

I don't know about Mac, but Iomega's "support" for OS/2

If it's as low as 5 minutes you have a point. Most ISPs it's
usually something like 20.
For those cases it is impolite to have something that keeps the
connection alive - after all, if they have a policy it is for some
(presumably) good reason.
A better bet is to use diald or something - except for that first
packet, it gives the illusion of a permanent connection.
Especially useful for getting email or slrnpull from cron.

No. (Well, at least not reliably.) You are supposed to have
*both* libc5 *and* glibc versions of each library that you may
need. You also need a mechanism for telling the dynamic linker
which C library each duplicated shared library belongs to
(either using "-lc" when building the shared library or using

Well I'm not using RH 6.0, but you're probably better off unistalling
Netscape 4.6 and using something like 4.08 which is known to be more
stable. Also, by default RH configures their systems to trap the
Ctrl+Alt+Backspace and Ctrl+Alt+Delete key combinations. Look at
/etc/inittab for instance.
To allow/disallow networking connections you usually have to edit
/etc/hosts.allow and /etc/hosts.deny. They should already exist and have
explanatory text on editing them.

I am using gcc-2.8.1 with libstdc++-2.8.1.1 taken from:
http://hpux.cae.wisc.edu/hppd/hpux/Gnu/
I took it from there because there was a lot of problems
when I tried to install egcs-1.1.2 on our systems.
I will try another time, but our HP systems are like
garbage, the system software is not correctly installed
especially the header files. For example, we have
/usr/include/X11 , /usr/include/X11R5 , /usr/include/X11R6
and there are three different versions of the h files.
Worse! Some aren't there that should be. xpm.h is in an
incredible directory like /efs/nfs/opt/include/xpm/xpm.h
and the libraries are in another place.
So thank you for answering me. Do you know where on the
web I could find the documentation on all gcc errors and
warnings? Because it is not in info.
