#53 iBCS-3.2

[Alex]

Changes from previous version:

1. Support for Kernel 2.6.20 added;
2. Fixed compilation problems on Red Hat line of products;
3. Fixed "sys_ipc" parameter passing;
4. Replaced "svr4_getdents" with "sys_getdents" in "sco/sysent.c".

Alex,
No change from iBCS-3.1 when executing an SCO Unix application. As was the case with the previous version, the database server process silently dies. Yet, the application runs just fine in single user mode. I will send you the execution trace.

On FedoraCore 6 with kernell 2.6.20.1 some old COBOL stuff ported
from AT&T UNIX works nice.
Thanks.

works brilliantly on Zenwalk linux (linux-2.6.20.3) with:
acucobol242 for sco osr 5.x.x
micro focus cobol for unix (sco osr 5.x.x)

Have no idea how to get socksys ready for testing...

Good work!

I have previously used implementations of Linux-ABI that are compiled into the kernel, and the applications I use require the following commands to be run for them to work:

echo 0x4100003 > /proc/sys/abi/defhandler_libcso || echo "Couldn't set default A BI handler - is /proc mounted?"
echo 0x4100003 > /proc/sys/abi/defhandler_lcall7 || echo "Couldn't set default A BI handler - is /proc mounted?"

Any idea how I can do the above using this patch? There is no /proc/sys/abi which I assume because this patch does not compile into the kernel like previous ones.

Regards,
Brad

Hi Brad,
Original iBCS2 package did not provide dynamic personality flag handling - neither does iBCS3 (at the moment).
To resolve your problem try this:
1) Run "utils/elf_mark -5 PathToYourBinaries";
2) If "1)" does not help replace "PER_SVR4" and "PER_OSR5" strings in "lcall/lcall.c" with "PER_OSR5 | MMAP_PAGE_ZERO";
3) If "2)" does not help - wait for iBCS-3.3.

Regards,
Alex.

Hi Robert,
Thanks for the Execution Traces provided. The problem you described appears since release 2.6.18 with introduction of VDSO. For "OpenSuse 10.2" insert "current->mm->context.vdso = VDSO_PRELINK;" above "out_free_file:" label into "coff/binfmt-coff.c".
Proper fix (applicable to all other kernel versions) will appear in iBCS-3.3.

Regards,
Alex.

Hi "brente",
In order "to get socksys ready for testing" in "udev" environment do this:
......
mknod /lib/udev/devices/socksys c 30 0
chmod 666 /lib/udev/devices/socksys
init 6
......
Regards,
Alex.

Alex, what i meant was; I have no network-aware application to test with :-) (back then)

I can also report success with acucobol runtime v 6.1.0, and YES! network works!
i also tried an evaluation copy of Acucorp's acuconnect server and other clients found it...

(Now, there _are_ linux versions of these newer releases, i know, but our licence is for the OpenServer version)

I have dynamic /dev so i put
mknod /dev/socksys c 30 0
ln -s /dev/null /dev/X0R
mknod /dev/spx c 30 1
in rc.local

i have a problem compiling it on debian etch:
when i call make i get the error /lib/modules/2.6.18-4-686/build not such file or directory

i create the directory build (/lib/modules/2.6.18-4-686 exists) and now if i call make as root i receive the following error:

pServer:~/ibcs# make
make -C /lib/modules/2.6.18-4-686/build M=/root/ibcs modules
make[1]: Entering directory `/lib/modules/2.6.18-4-686/build'
make[1]: *** No rule to make target `modules'. Stop.
make[1]: Leaving directory `/lib/modules/2.6.18-4-686/build'
make: *** [all] Error 2

someone can help me to understand this error?

I am running into similar issues with compiling on kubuntu.

Is there a "howto" for this new iBCS 3.x? I'd really appreciate one.

The same happens with version 3.3
