Jean Delvare 6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

arch/alpha/kernel/err_common.c
arch/alpha/kernel/err_ev6.c
arch/alpha/kernel/err_ev7.c

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

Note that this patch depends on another header fixup patch I submitted
to LKML yesterday:
  [PATCH] scatterlist.h needs types.h

Steve Wise ebb90986e1 RDMA/iwcm: iw_cm_id destruction race fixes
iwcm iw_cm_id destruction race condition fixes:

- iwcm_deref_id() always wakes up if there's another reference.
- clean up race condition in cm_work_handler().
- create static void free_cm_id() which deallocs the work entries and then
  kfrees the cm_id memory.  This reduces code replication.
- rem_ref() if this is the last reference -and- the IWCM owns freeing the
  cm_id, then free it.

Krishna Kumar 9ab1ffa877 RDMA/iwcm: Fix comment for iwcm_deref_id() to match code
In iwcm_deref_id(), the comment says : "If the last reference is being
removed and iw_destroy_cm_id is waiting, wake up the waiting
thread". The second part of the comment, "and iw_destroy_cm_id is
waiting," is wrong, since this function either wakes the waiter
already waiting in iwcm_deref_id, or enables it (so that when
wait_for_completion() is performed later, it will immediately return).

Krishna Kumar 83b9658623 RDMA/iwcm: Fix memory leak
If we get IW_CM_EVENT_CONNECT_REQUEST message and encounter an error
(not in the LISTEN state, cannot create an id, cannot alloc
work_entry, etc), then the memory allocated by cm_event_handler() in
the event->private_data gets leaked. Since cm_work_handler has already
put the event on the work_free_list, this allocated memory is
leaked. High backlog value can allow DoS attacks.

Krishna Kumar 33ba0fa9f3 RDMA/iwcm: Fix memory corruption bug in cm_work_handler()
Possible memory corruption scenario: after putting the work entry back
on the work_free_list, we call process_event() which dereferences
work->event, which could have been modified to another value
meanwhile.

Tom Tucker 922a8e9fb2 RDMA: iWARP Connection Manager.
Add an iWARP Connection Manager (CM), which abstracts connection
management for iWARP devices (RNICs).  It is a logical instance of the
xx_cm where xx is the transport type (ib or iw).  The symbols exported
are used by the transport independent rdma_cm module, and are
available also for transport dependent ULPs.
