[ofa-general] libsdp in OFED 1.1

[Jim Mott]

With the setup you describe, I have no problems under OFED 1.2.  SDP does get used automatically, and ls does not complain.


I do not have any experience with SDP under OFED 1.1.  I will try to look at it soon.

The OFED 1.1 library code in port.c includes a close() function, so the easy answer is not going to do it.

All my testing has been with the same libsdp.conf setup you are using (the 1.2 default), so I do not expect your setup to cause any problems.

The entry in modprobe.conf.local is the normal thing.  I would not expect it to be causing you any problems.

All my testing has been with the local environment (LD_LIBRARY_PATH, LD_PRELOAD) overrides instead of /etc/ld.so.preload.  Note that with your putting the fully qualified path for the 64 bit library in /etc/ld.so.preload, there will be issues with 32 bit executables.  Not sure if that is getting you with ls, but I have seen strange problems with other things.

Could you remove your entry from /etc/ld.so.preload, set the environment variables as described in my original note by hand, and retry the ls command?

Hi Jim,

We are actually using OFED 1.1. Hopefully we'll move to 1.2 in a few weeks. The systems using it are SLES 9 SP3.

Uname -a:
Linux oracle 2.6.5-7.244-smp #1 SMP Mon Dec 12 18:32:25 UTC 2005 x86_64 x86_64 x86_64 GNU/Linux

I have added alias net-pf-27 ib_sdp to modprobe.conf.local
I have modified /usr/local/ofed/etc/libsdp.conf to have the following lines:
log min-level 9 destination syslog
use both server "/usr/local/bin/netserver" *:*
use both client "/usr/local/bin/netperf" *:*
And I created /etc/ld.so.preload and have:
/usr/local/ofed/lib64/libsdp.so

Is there a close function in ofed 1.1? Perhaps I should try to add that to port.c for 1.1?

My reply to your email bounced...
5.1.0 - Unknown address error 550-'5.1.1 unknown or illegal alias: <removed>@austin.rr.com'

Thanks!
Jonathan

Hi,
  I have just taken over support for libsdp and am feeling my way here.
Probably I should have replied to the list, but this works too.

  I assume you are using OFED 1.2 version of the code.  There is a close()
function in that code (port.c), so there is something fishy here.  Could you
send a little more info please.  Stuff like distro, 32/64, and perhaps the
script/commands you use to automate the preload process.

Something like:

  # uname -a
  Linux sw106.lab.mtl.com 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:32:02 EDT \
  2006 x86_64 x86_64 x86_64 GNU/Linux

  # export LD_LIBRARY_PATH=/usr/local/ofed/lib64:/usr/local/ofed/lib
  # export LD_PRELOAD=libsdp.so
  # export LIBSDP_CONFIG_FILE=/etc/infiniband/libsdp.conf 

  # ls 
  config_parser.c   config_scanner.c   libsdp.la  Makefile     match.c
port.lo
  config_parser.h   config_scanner.lo  log.c      Makefile.am  match.lo
sdp_inet.h
  config_parser.lo  libsdp.h           log.lo     Makefile.in  port.c
socket.c


Thanks,
Jim

Hello,

I have been using libsdp, and preloading it with the application. I would
like to have it automatically preloaded, but am concerned about some error
messages that seem harmless. So I don't want to have our client use the
ld.so.preload if there are going to be messages.

I see the following when I run a simple 'ls'

# ls
Wed Jul 18 06:11:09 2007 ls[8105] libsdp Error close: no implementation for
close found
 .
..
#

Any suggestions?

I have the following in libsdp.conf
Log min-level 9 destination syslog
Use both server netserver *:*
Use both client netperf *:*

Our client is interested in having weblogic communicate with the oracle DB
using SDP, and the interface to oracle and weblogic being accessible via
tcp/ip over Ethernet as well.

Thanks!
Jonathan
