Re: [PATCH] libibnetdisc: fix outstanding SMPs countung
On 09:52 Wed 14 Apr , Ira Weiny wrote:
But then it blocks process_mads() to loop forever after single
send_smp() failure (with all empty queues and umad_recv() running
without timeout).
But moving the cl_qmap_insert below the send call fixes that.
It doesn't:
int process_mads(smp_engine_t * engine)
{
int rc = 0;
while (engine-num_smps_outstanding 0) {
if ((rc = process_smp_queue(engine)) != 0)
return rc;
while (!cl_is_qmap_empty(engine-smps_on_wire))
if ((rc = process_one_recv(engine)) != 0)
return rc;
}
return 0;
}
After send_smp() failure engine-num_smps_outstanding still be 0 and
will be never decreased (tested).
However, it does cause a memory leak because the smp is no longer in
the smp_queue_head list.
This is correct about leaking.
It needs to be put back on that list to be
retried with a limit on the retries (to prevent what you are saying
here.)
We have already retries mechanism implemented in umad_send(), so likely
failed MAD should be just dropped and freed:

Are you seeing a hang?
I'm seeing endless loop.
I have seen a hang when running iblinkinfo -S guid.
What do you mean hang? Endless loop?
However, the
problem is not with send_smp. I am seeing the mad going on the wire
and returning (according to madeye) but I am not receiving it from
umad_recv. I don't know why. If I run with 1 outstanding mad it
works???
Do you see this with current master (for me 'iblinkinfo -S' works fine,
but I have only two switches).

Re: [PATCH] opensm/osm_dump.c: dump SL2VL tables
Hi Yevgeny, If this patch is included on top of my torus-2QoS patchset, you might want the addition below. This is because my patchset causes SL2VL maps to always be set when a routing engine registers its intent to do so by providing an update_sl2vl() function, without requiring opensm to be invoked with -Q. So we want to dump SL2VL tables also in that case. On Thu, 2010-03-25 at 09:56 -0600, Yevgeny Kliteynik wrote: Hi Sasha, Dumping SL2VL tables in ROUTING verbosity level when QoS is on.

You need to make your patchset towards 2.6.35 (using net-next-2.6 tree) rather than 2.6.34 (using linux-2.6 tree). Therefore, this patch being queued for 2.6.35 (through net-next-2.6 tree) should be okay for you.
