Hello,
In opensm/opensm/osm_sm_state_mgr.c:osm_sm_state_mgr_check_legality(), I
noticed that the only valid signals that the SM can get while in the
IB_SMINFO_STATE MASTER are:
- OSM_SM_SIGNAL_HANDOVER
- OSM_SM_SIGNAL_HANDOVER_SENT
However, in opensm/opensm/osm_sm_state_mgr.c:osm_sm_state_mgr_process(), we
see that the following signals can be received in the master state:
- OSM_SM_SIGNAL_POLLING_TIMEOUT
- OSM_SM_SIGNAL_HANDOVER
- OSM_SM_SIGNAL_HANDOVER_SENT
- OSM_SM_SIGNAL_WAIT_FOR_HANDOVER
- OSM_SM_SIGNAL_DISCOVER
Is this a bug, or am I missing anything here ?
I don't see an immediate bug here. osm_sm_state_mgr_check_legality() is
used only during SMInfo request processing so it covers only this flow
path and osm_sm_state_mgr_process() is called in different places.
OK, I see, Thanks for the tip.
I have another question: I compiled opensm and ran it from a different
prefix.
Because I'm not root, I wanted opensm to log onto a path that was not
/var/cache. At first, I forgot to set the OSM_CACHE_DIR environment
variable and got the following error:
Error from osm_opensm_init: IB_INSUFFICIENT_RESOURCES.
Looking at strace, I quickly found what was wrong:
lstat("/var/cache/opensm/", 0x7ffff7cbf970) = -1 ENOENT (No such file or
directory)
mkdir("/var/cache/opensm/", 0755) = -1 EACCES (Permission denied)
Shouldn't opensm log something more accurate w.r.t this issue ? Strictly
speaking, it's not really an IB_INSUFFICIENT_RESOURCES issue.
Cheers,
Vincent
