Hi,
when starting openser 1.3.1 it doesn't really start, but stops after
processing a SIGILL. When perfoming
strace -f /usr/local/sbin/openser
I get the following output (these are only the last few lines):
time([1208951399]) = 1208951399
stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=837, ...}) = 0
stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=837, ...}) = 0
stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=837, ...}) = 0
send(3, "<143>Apr 23 13:49:59 /usr/local/"..., 147, MSG_NOSIGNAL) =
147
--- SIGILL (Illegal instruction) @ 0 (0) ---
Process 12746 detached
I've compiled openser from source on the same machine. When starting
openser with -V everything works just fine. Output:

So I guessed the problem could occur inside a module. I removed auth.so

But, it doesn't receive a SIGILL anymore, but SIGTERM. Output from strace:

Hi Christian,
Any logs from openser during startup? if not, try to enable debug
(debug=6) and see where is stops.

Bogdan

Hi Bogdan,
when logging to syslog these are the last lines I get:

All other messages I get are either DBG or INFO, no errors. But now I
tried something different. I've set "fork=no", and now I'm getting a
corefile. Backtrace of gdb is:

(gdb)
Looks like calling init_mod() recursively. I didn't study the openser
code, but this backtrace looks strange to me.
If anybody is interested in the whole corefile, please mail me directly.
I don't want to post such a large file to the list.
Thanks a lot for your help,
Christian

Hi Christian,
The line the trace refer at is:
sec_rand[i] = 32 + (int)(95.0 * rand() / (RAND_MAX + 1.0));
I suspect the rand() function, as there were some previous reports about
it....:(
Could you try alter the code and replace the rand() with some number
just to see if it won't crash?

Bogdan

Hi Bogdan,
I tried replacing the rand() function in that line, but afterwards I got
a core file at another line. Still with SIGILL.
But I think I've found a solution: In "Makefile.defs", for i386 with gcc
3.x I removed the following line (line 592):
-march=$(CPU_TYPE)
CPU_TYPE would be set to "prescott" in that case, but the manpage of gcc
states prescott is "Improved version of Intel Pentium4 CPU...". My
machine is a Pentium III, so it doesn't understand the P4 code generated
by gcc. I recompiled openser without "-march" and it seems everything
works fine now.
I think the Makefile still needs to be fixed for the other architectures
and gcc versions.
Regards,
Christian

Hi Bogdan,
when logging to syslog these are the last lines I get:
Apr 23 16:12:02 192 /usr/local/sbin/openser[12817]:

All other messages I get are either DBG or INFO, no errors. But now I
tried something different. I've set "fork=no", and now I'm getting a
corefile. Backtrace of gdb is:
(gdb) bt

(gdb)
Looks like calling init_mod() recursively. I didn't study the openser
code, but this backtrace looks strange to me.
If anybody is interested in the whole corefile, please mail me
directly. I don't want to post such a large file to the list.
Thanks a lot for your help,
Christian

Hi Christian,
Any logs from openser during startup? if not, try to enable debug
(debug=6) and see where is stops.

I tried replacing the rand() function in that line,
but afterwards I got
a core file at another line. Still with SIGILL.
But I think I've found a solution: In "Makefile.defs", for i386 with gcc
3.x I removed the following line (line 592):
-march=$(CPU_TYPE)
CPU_TYPE would be set to "prescott" in that case, but the manpage of gcc
states prescott is "Improved version of Intel Pentium4 CPU...". My
machine is a Pentium III, so it doesn't understand the P4 code generated
by gcc. I recompiled openser without "-march" and it seems everything
works fine now.
I think the Makefile still needs to be fixed for the other architectures
and gcc versions.
Hi Christian,
i think the correct statement for (a recent) 3.X gcc would be
either 'mcpu=prescott' or 'mtune=prescott'. I don't know why march is
used in
this case, for the x86_64 case its correct. Then the compiler will only
optimize for this special processor, but the code will nevertheless run on
i386 machines too.
The 'prescott' type is unfortunally not available on older gcc, so i
used 'pentium4' instead. I'll make a fix on svn, could you perhaps test this?
Thank you,
Henning

Hi Henning,
you're right. The manpage of gcc says for mtune:
While picking a specific cpu-type will schedule things appropriately
for that particular chip, the compiler will not generate any code
that does not run on the i386 without the -march=cpu-type option
being used.
But as I have a Pentium III, I wouldn't benefit of "mtune=prescott",
although the compiled code will run on my machine, of course. I think
the correct way would be to have a configure script determining the CPU
type and using that type for mtune (I know, that would be a lot of
work....).
When you fixed the Makefile in SVN, just tell me, so I can test it.

Hi Christian,
sure, this would be the best way. But as both gcc 3.X and pentium3 are not
that much in use anymore, i think that 'pentium4' as optimization works for
the most people at the moment.
I just commited the fix for the trunk and 1.3 branch.

Hi Henning,
Thanks for the fix. I guess there are several compile optimization that
are a bit too aggressive, so most sure this will not be the last fix in
this area ;).

Bogdan

I've just downloaded and compiled the latest snapshot
(openser-1.3.x-svn-20080428-141101.tgz). It seems to run fine.
Thanks for your support,
