The -m31 option creates objects and binaries in the ELF32 format.
Without the option or with -m64 the ELF64 format is used.

A 64-bit kernel recognizes the format of the binary and starts it
in the appropriate mode. Native for ELF64 or compat for ELF32.
The addressing mode is AMODE-64 for native 64-bit programs and
AMOED-31 for compat 31-bit code.

The process is started by the kernel in the "correct" mode,
you can not specify that a ELF32 binary is started in AMODE-64.

The kernel enforces limits as well, e.g. with a 31-bit compat
process (ELF32) you can not map anything above the 2GB line.
The format of the signal handler frame is different as well
for ELF32 vs ELF64.

But you can switch the addressing mode in your program with
the sam24, sam31, and sam64 instructions. If the code of the
program is at a location that goes along with the chosen
addressing mode, the CPU will happily execute the instructions.
You better not forget to switch back to the default mode before
calling a function in the runtime environment. Otherwise your
program will quickly terminate.

RHEL 7.1 was some time ago.  RHEL 7 first dropped: 2014 06 10

A better resource (in terms of being specific to Red Hat's
most current approach -- 7.5 dropped in beta: 2018 01 24, and
formally as an update: 2018 04 24) is the documentation they
maintain [I opened a few bugs on it during the beta period
which were promptly and professionally addressed.  The net net
is that is was clear that Red Hat and IBM were explicitly
working (sadly in private bugs) on the 7.5 Release Notes in
to correct some detail in RH's documentation presence]

There are some quesions about Red Hat having unwittingly
changed exported headers in kernel-devel with the 'kernel-alt'
package series.  Recall the mention by Neale noticed of some
side effects flowing through to python 2, and systemd, as side
effects of last week, (repository closure was broken, more)
and which have delayed the formal ClefOS 7.5 update respin a
bit as the parts for a good installing ISO are sorted out

ClefOS 7.4 is fine

RedHat/ClefOS configuration file

I'm following in the IBM Redbook "The Virtualization Cookbook for IBM z Systems 
Volume 2: Red Hat Enterprise Linux 7.1 Servers", and I'm at step 6:


6. Edit the GENERIC PRM file by adding the correct parameters and system 
information as shown in the following example:

I would like the z/Linux kernel to be modified
to start an ELF32 binary in AM64 and have access
to a full 4 GiB address space. And when it starts
an ELF32 binary it should zero out the high 32 bits
of the 64-bit registers using LMH R0,R15,=16F'0'.

Is there any technical barrier to doing that?

Thanks. Paul.

Leaving aside technical viability for a moment, I have a basic application
change management concern. Shouldn't the program binary make its own
decisions about changing its execution environment in such fashion? I can
imagine, without much imagination, many possible program breakages if the
kernel changed the execution environment that way.

At a minimum, any such kernel behavioral change would necessarily have to
be selective, with some sort of whitelisting mechanism. However, if you
agree that each program binary should properly make such decisions for
itself, with much better knowledge of its own capabilities for healthy
living within that new memory environment of up to 4 GiB, then the very
same application developer(s) could make an ELF64 (-m64) decision for the
whole program. Or, alternatively, and if I understand Martin Schwidefsky
correctly, the program developer could make a more selective, sub-program
sam64 in/out decision if she needs memory above the 2 GiB bar.

The hobbyist community shared my concern in another but broadly similar
context when it modified the MVS 3.8j operating system, designed for 24-bit
addressing (16 MiB), to add 31-bit addressing (2 GiB) in what they dubbed
"MVS/380." However, as far I know they didn't attempt to force that new
addressing mode onto any 24-bit programs. Instead, they provided the
above-line memory services and then allowed particular programs to exploit
those additional services if/as they wished, but only if they wished. The
fundamental reason they added those 31-bit services, besides fun and
enjoyment, is that MVS 3.8j simply didn't support anything but 24-bit
addressing. However, that's not a problem with Linux (or with z/OS). The
operating system already supports 64-bit addressing really well, and
developers are already free to exploit those capabilities, with knowledge
of their own code and its quirks and foibles.

The administrator managing Linux can enforce memory resource limits, so if
there's a desire to limit ELF64 (or sam64'ed) application memory
consumption to 4 GiB, no problem. The program might not like that either,
of course, but the OS can enforce such limits.

It seems like your idea would be a neat, creative trick if viable, but how
would help?

Hi, Frank

Recall that the URL mangling which you mentioned you saw would bite here

As I recall, in a text mode install, alt-F7 or such changed to different VT's 
so you could view what was being sent (the details are on one of the secondary 
initial boot screens, which you many toggle between)

Not sure what your network map looks like, of course, but before you beat 
yourself up, talk with your networking support about getting an unfiltered port 

Alternatively a 'mirror' can be set up 'inside' the protected perimeter and on 
the same network segment as the target machine to be installed, on a local PC 
running Linux fairly trivially

Re: Red Hat/ClefOS configuration file

[Filipe Miranda]

Hi,

Is this a network install ? If yes, the the installer is not able to find your 
installation tree. This is why Step #3 is falling.

on the GENERIC.PRM you have to define the install tree:

Example:
inst.repo=http://download.lab.bos.redhat.com/released/RHEL-7/7.0/Server/s390x/os

I prefer http, its fast and easy once you have the contents available though 
the web server.



Kind Regards,
