RDMA/cma: Increase the IB CM retry count in CMA

2006-09-14T20:55:30+00:00

3 seems like a low number of IB Communication Manager retries to set;
we see connections failing under stress, and in any case 3 just looks
like an arbitrary number.  15 is the max value allowed by the
InfiniBand spec.

IB/core: Fix SM LID/LID change with client reregister set

2006-08-16T16:54:47+00:00

After commit 12bbb2b7be7f5564952ebe0196623e97464b8ac5, when SM LID
change or LID change MAD also has a client reregistration bit set,
only CLIENT_REREGISTER event is generated.

As a result, the sa_query module and the cache module don't update the
port information, and ULPs (e.g. IPoIB) stop working.  This is the
regression we observe as compared to 2.6.17.

Rather than generate multiple events (which would have negative
performance impact), let us simply let cache and SA query respond to
reregister event in the same way as to LID and SM change events.

IB/uverbs: Avoid a crash on device hot remove

2006-08-03T17:56:42+00:00

Wait until all users have closed their device context before allowing
device unregistration to complete.  This prevents a crash caused by
referring to stale data structures.

A better solution would be to have a way to revoke contexts rather
than waiting for userspace to close the context, but that's a much
bigger change that will have to wait.  For now let's at least avoid
the crash.

IB/mad: Validate MADs for spec compliance

2006-07-24T16:18:07+00:00

Validate MADs sent by userspace clients for spec compliance with
C13-18.1.1 (prevent duplicate requests and responses sent on the
same port).  Without this, RMPP transactions get aborted because
of duplicate packets.

This patch is similar to that provided by Jack Morgenstein.

IB/uverbs: Fix lockdep warnings

2006-07-23T22:16:04+00:00

Lockdep warns because uverbs is trying to take uobj->mutex when it
already holds that lock.  This is because there are really multiple
types of uobjs even though all of their locks are initialized in
common code.

IB/uverbs: Fix unlocking in error paths

2006-07-23T22:16:03+00:00

ib_uverbs_create_ah() and ib_uverbs_create_srq() did not release the
PD's read lock in their error paths, which lead to deadlock when
destroying the PD.

[PATCH] IB/core: use correct gfp_mask in sa_query

Avoid bogus out of memory errors: fix sa_query to actually pass gfp_mask
supplied by the user to idr_pre_get.

[PATCH] fmr pool: remove unnecessary pointer dereference

2006-07-15T04:53:51+00:00

ib_fmr_pool_map_phys gets the virtual address by pointer but never writes
there, and users (e.g.  srp) seem to assume this and ignore the value
returned.  This patch cleans up the API to get the VA by value, and updates
all users.
