[PATCH] gfp flags annotations - part 1

2005-10-08T22:00:57+00:00

 - added typedef unsigned int __nocast gfp_t;

 - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
   the same warnings as far as sparse is concerned, doesn't change
   generated code (from gcc point of view we replaced unsigned int with
   typedef) and documents what's going on far better.

[IB] uverbs: Close some exploitable races

2005-09-26T20:01:03+00:00

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.

[PATCH] IB: Fix data length for RMPP SA sends

2005-09-19T20:51:01+00:00

We need to subtract off the header length from our payload
length when sending multi-packet SA messages.

[PATCH] IB: fix CM use-after-free

2005-09-10T03:52:00+00:00

If the CM REQ handling function gets to error2, then it frees
cm_id_priv->timewait_info.  But the next line goes through
ib_destroy_cm_id() -> ib_send_cm_rej() -> cm_reset_to_idle(),
which ends up calling cm_cleanup_timewait(), which dereferences the
pointer we just freed.  Make sure we clear cm_id_priv->timewait_info
after freeing it, so that doesn't happen.

Make sure that userspace does not retrieve stale asynchronous or

2005-09-09T22:55:08+00:00

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.

[PATCH] IB: Move SA attributes to ib_sa.h

2005-09-09T22:24:04+00:00

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.
