[openib-general] Bug in IBMgtSim?

[Sven-Arne Reinemo]

Hi,

There seemed to be a bug in IBMgtSim where it forwards packets received
from the SM back onto the port where the SM is connected. OpenSM just
drops the packet so it does not seem very problematic, but I am just
checking to see if anyone else see this behaviour. Below are an example
from the log files.

Packet dropped by OpenSM:

Dec 15 15:21:34 992520 [B44E3BB0] -> Duplicate TID 0x6A7B00001234
received (not a response). Dropping the MAD.


Packets forwarded to the SM (the first one is the one that is dropped):

-I- Using random seed:96960
-I- Parsing topology definition:/simulator/scalability/test_top.topo
-I- Defined 3/3 systems/nodes
-I- Init fabric: fabric:1
-I- Started server: opensm.simula.no port:60493
-I- Ready to serve
-I- Connecting: sock9 127.0.1.1 48227
