Sean,
I'm debugging some disconnect related race in iser - and wanted to check
with you something re the CM/RDMA-CM state machine: I see that when a
disconnected is initiated by the passive side (iser target) of a
connection, such that the active side (iser initiator) gets
hca_id: mlx4_0

node_guid: 0003:ba00:0100:b1d8

mmm, so can these bogus states for rdma_disconnect to be called be
better defined? basically, for the

By bogus I mean
By bogus I mean calling disconnect when the QP has never been connected, or
calling

is that -EINVAL? also, basically a QP could have buffers posted to it

Hello again, Vladimir!
To set up /dev/mst/mt25418_pci_cr0 manually I've followed up
what /etc/init.d/mst start does.
I've seen that it uses the minit tool which is part of the arch
dependent mft-package.
Is there maybe a possibility to get minit for sparc64?
Otherwise I can't init
no_fallback_routing_engine is a convenience flag and not a configurable
option, so it should not be in osm_subn_opt_t.

This patch fixes several major issues when config files are rescanned.
First, config file changes were only noticed if users listed the
config file option in the file. If a user commented out an option
(or uncommented a previously commented out option) the change may
not be noticed.
Second,
Note that the new config file parsing code, different osm_subn_opt_t
structures do not share pointers to the same strdup'ed memory.
Therefore, this memory must be freed before reallocing to avoid
a memleak.

I was talking on the QP physical state (e.g error that causes
flushes) not the state w.r.t the IB CM.

Those if-statements are superfluous - invoking free(NULL) is safe. See
