Re : [uml-user] Kernel 2.4.22-5 on Debian / Unstable

Hi 

I don't know if you got an answer, but here comes the solution : the header file
of the kernel source with a Debian Unstable are wrong. You can get ride of this
error with this (your arch is the arch of your computer, in most case i386)

cp /usr/include/asm/ldt.h /usr/include/asm/ldt.h.bak
and then
cd <uml kernel source tree>
cp include/asm-<your arch>/ldt.h /usr/include/asm/ldt.h.
It's not a pretty solution, but it work.

And then, you'll have another error, with ptrace_user, so edit 
<uml kernel source tree>/arch/um/sys-i386/ptrace_user.c and add 
#include "linux/ptrace.h"
to the list of the included files in the top of the file.

And don't forget to compile also your own uml-utilities for your kernel.

For your gcc question, try to use the alternatives to update your version :
update-alternatives --install /usr/bin/gcc cc /usr/bin/gcc-2.95 0
update-alternatives --install /usr/bin/gcc cc /usr/bin/gcc-3.3  1
and then 
update-alternatives --config cc

Hope that it'll help you

[uml-user] 《木子美网络遗情风暴》

[uml-user] kernel panic after starting klogd

Dear list,

I've got a stupid bug in my recent 2.4.22-6um kernel.

I'm running 2.4.23 with skas3 on the host (a via epia/666 with 256MB
Ram), have TEMPDIR on tmpfs and try to run 2.4.22-6um patched with mppe
and super-free-swan.

The static version (e.g. no modules) works fine, but I've to choose
between mppe or freeSwan (as both defnie sha1 / md5 and i'm not able t
link both).

The modular version with debuging enabled works fine, but the version
I'd like to use (without debuging) oopses:

    Kernel panic: Kernel mode fault at addr 0x4280e000, ip 0x400e3958

shortly after starting klogd

    daemon klogd -u syslog

when started during boot it's unable to print [ok], when started from
the shell it sometimes returns to the input prompt but panics right
afterwards.

i've suspected faulty memory, but running memtest86 for 12 runs did not
turn up any error.

Starting more programs on the host, to change the memory map did not
help either.

Any ideas how to debug this?

OTOH: if I would be able to use super-freeswan, pppoe (rp-pppoe) and
      pptp with mppe from a not modular kernel I'd be even more happy. 
      But I only got linux-2.4.19-openssl-0.9.6b-mppe.patch and can't
      find a more recent version.

BTW: I'm running Trustix 2.0 on both host and instance.

Verify that you have a /usr/include/linux/stddef.h header(this path is the 
relevant one) and make sure it contains these lines:

#undef offsetof
#define offsetof(TYPE, MEMBER) ((size_t) &((TYPE *)0)->MEMBER)

Re: [uml-user] problems in compiling user mode linux and normal linux v2.4.22

Would you please post a lot of lines ABOVE these ones? The error text is 
above.

Would you also tell us what version of Gcc and which distribution you use?
Note that to compile the normal kernel you mustn't type
 make
after "make dep", but 
 make bzImage
and then
 make modules && make modules_install

On my own, I use this contracted form after kernel configuration(make 
xconfig):
 make dep bzImage modules modules_install

or, if I have any problem, I add the cleaning with this form:
 make dep clean bzImage modules modules_install

RE: [uml-user] bug: [ 851759 ] SuSE YAST in textmode does not work

I have experienced the same problem.  I have not found the solution 
either.  To work around it I open a second session to the same UML I ran 
YaST in.  I run top and kill the stuck y2base.  It will spawn one more 
y2base that again gets "stuck" and I kill it also.  After killing it 
twice YaST proceeds forward as usual.  There are times it will not get 
stuck at all, but rarely.  Something y2base is checking in UML is not 
returning as all the CPU time goes to the kernel when it is hung.  

I think it is a UML bug, but I haven't found the time to isolate where 
it is hanging up.

What version of SuSE are you using in the UML?  I've only worked with 
8.1 and 8.2.  I'm curious if SuSE has done anything to fix this in 9.0 
since they are working more with UML now.
