When a local operation (invalidate mr, reg mr, bind mw) is finished there
will be no ack packet coming from a responder to cause the wqe to be
completed. This may happen anyway if a subsequent wqe performs
IO. Currently if the wqe is signalled the completer tasklet is scheduled
immediately but not otherwise.
This leads to a deadlock if the next wqe has the fence bit set in send
flags and the operation is not signalled. This patch removes the condition
that the wqe must be signalled in order to schedule the completer tasklet
which is the simplest fix for this deadlock and is fairly low cost. This
is the analog for local operations of always setting the ackreq bit in all
last or only request packets even if the operation is not signalled.

Currently the rdma_rxe driver has a security weakness due to giving
objects which are partially initialized indices allowing external actors
to gain access to them by sending packets which refer to their
index (e.g. qpn, rkey, etc) causing unpredictable results.
This patch adds a new API rxe_finalize(obj) which enables looking up pool
objects from indices using rxe_pool_get_index() for AH, QP, MR, and
MW. They are added in create verbs only after the objects are fully
initialized.
It also adds wait for completion to destroy/dealloc verbs to assure that
all references have been dropped before returning to rdma_core by
implementing a new rxe_pool API rxe_cleanup() which drops a reference to
the object and then waits for all other references to be dropped. When
the last reference is dropped the object is completed by kref. After that
it cleans up the object and if locally allocated frees the memory. In the
special case of address handle objects the delay is implemented separately
if the destroy_ah call is not sleepable.
Combined with deferring cleanup code to type specific cleanup routines
this allows all pending activity referring to objects to complete before
returning to rdma_core.

1.2) flow meter
1.3) Execute ASO action for flow entry
1.4) enhanced CQE compression
2) Add ICM header-modify-pattern RDMA API
Leon Says
=========
SW steering manipulates packet's header using "modifying header" actions.
Many of these actions do the same operation, but use different data each time.
Currently we create and keep every one of these actions, which use expensive
and limited resources.
Now we introduce a new mechanism - pattern and argument, which splits
a modifying action into two parts:
1. action pattern: contains the operations to be applied on packet's header,
mainly set/add/copy of fields in the packet
2. action data/argument: contains the data to be used by each operation
in the pattern.
This way we reuse same patterns with different arguments to create new
modifying actions, and since many actions share the same operations, we end
up creating a small number of patterns that we keep in a dedicated cache.
These modify header patterns are implemented as new type of ICM memory,
so the following kernel patch series add the support for this new ICM type.

during a CM connection attempt, the RDMA-CM would take a lot of time till
it disconnects and timesout due to the incorrect MAC address.
Now when we get a NETEVENT_NEIGH_UPDATE we check if it is due to a failover

to spare the unnecessary waiting for the timeout.

in the tree, since the tree data is a list of all ids with matching destination IP.
The tree allows fast and efficient lookup of ids using an ifindex and

delayacct: track delays from write-protect copy
The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.
It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32. It shoudln't have been a bitmap in the first
place. The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.
The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.
So just use a regular integer.
In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).
That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953fd2 ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
