Roland Dreier 63c47c286d [IB] uverbs: Close some exploitable races
Al Viro pointed out that the current IB userspace verbs interface
allows userspace to cause mischief by closing file descriptors before
we're ready, or issuing the same command twice at the same time.  This
patch closes those races, and fixes other obvious problems such as a
module reference leak.

Some other interface bogosities will require an ABI change to fix
properly, so I'm deferring those fixes until 2.6.15.

Roland Dreier 63aaf64752 Make sure that userspace does not retrieve stale asynchronous or
completion events after destroying a CQ, QP or SRQ.  We do this by
sweeping the event lists before returning from a destroy calls, and
then return the number of events already reported before the destroy
call.  This allows userspace wait until it has processed all events
for an object returned from the kernel before it frees its context for
the object.

The ABI of the destroy CQ, destroy QP and destroy SRQ commands has to
change to return the event count, so bump the ABI version from 1 to 2.
The userspace libibverbs library has already been updated to handle
both the old and new ABI versions.

Roland Dreier 2e9f7cb786 [PATCH] IB: Add struct for ClassPortInfo
Add structure definition for ClassPortInfo format.  This is
needed for (at least) handling CM redirects.

SA: Move SA attributes to ib_sa.h so are accessible to more than
sa_query.c. Also, remove deprecated attributes and add one missing one.

Sean Hefty 0b2b35f681 [PATCH] IB: Add user-supplied context to userspace CM ABI
- Add user specified context to all uCM events.  Users will not retrieve
  any events associated with the context after destroying the corresponding
  cm_id.
- Provide the ib_cm_init_qp_attr() call to userspace clients of the CM.
  This call may be used to set QP attributes properly before modifying the QP.
- Fixes some error handling synchonization and cleanup issues.
- Performs some minor code cleanup.

Roland Dreier a4d61e8480 [PATCH] IB: move include files to include/rdma
Move the InfiniBand headers from drivers/infiniband/include to include/rdma.
This allows InfiniBand-using code to live elsewhere, and lets us remove the
ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles.
