Current implementation allows each qp to have only one send engine. As
such, each qp has only one list to queue prebuilt packets when send engine
resources are not available. To improve performance, it is desired to
support multiple send engines for each qp.
This patch creates the framework to support two send engines
(two legs) for each qp for the TID RDMA protocol, which can be easily
extended to support more send engines. It achieves the goal by creating a
leg specific struct, iowait_work in the iowait struct, to hold the
work_struct and the tx_list as well as a pointer to the parent iowait
struct.
The hfi1_pkt_state now has an additional field to record the current legs
work structure and that is now passed to all egress waiters to determine
the leg that needs to wait via a new iowait helper. The APIs are adjusted
to use the new leg specific struct as required.
Many new and modified helpers are added to support this change.

The driver-provided function check_send_wqe allows the hardware driver to
check and set up the incoming send wqe before it is inserted into the swqe
ring. This patch will rename it as setup_wqe to better reflect its
usage. In addition, this function is only called when all setup is
complete in rdmavt.

If a MAD packet has incorrect header information, the logic uses the reply
path to report the error. The reply path expects *resp_len to be set
prior to return. Unfortunately, *resp_len is set to 0 for this path.
This causes an incorrect response packet.
Fix by ensuring that the *resp_len is defaulted to the incoming packet
size (wc->bytes_len - sizeof(GRH)).

IB has additional protections with SELinux that cannot be extended to the
DEVX domain. SELinux can restrict access to pkeys. The first version of
DEVX blocked IB entirely until this could be understood.
Since DEVX requires CAP_NET_RAW, it supersedes the SELinux restriction and
allows userspace to form arbitrary packets with arbitrary pkeys.
Thus we enable IB for DEVX when CAP_NET_RAW is given.

Currently mmap_sem is read locked while pinning the memory. In a
multi-threaded application of a process, holding mmap_sem lock creates
contention with other threads who might be either registering memory,
creating QPs or simply doing mmap() as such operations also require to
hold the mmap_sem write lock.
All such operation cannot make forward progress until one memory pin
operation is completed. It becomes more worse if the memory is unpinned
and/or memory registration is large (in GB range).
Therefore, instead of holding mmap_sem for too long (for whole region
pinning), acquire and release the lock for every few pages. For example
on x86 with 4K page size, acquire and release mmap_sem for every 2Mbytes
memory chunk.
This allows other competing threads to make progress who might wish to
hold mmap_sem for shorter duration.
When memory registration latency is measured using [1] for memory sizes
ranging from 4K to 48GB, <= 1% or 0.5% degradation is noticed. In many
runs no difference is seen other than run-to-run variance.
In other targeted tests of users with large memory, desired improvements
are seen due to reduced contention of mmap_sem.
[1] https://github.com/paravmellanox/rtool
$ rdma_resource_lat -c 1 -s 48G -a -u L -i 500 -A
It registers pinned memory from 4K to 48GB size with 500 iterations for
each memory size.
$ rdma_resource_lat -c 1 -s 12G -a -u L -i 500 -t 4
4 competing threads pin memory, each of 12GB size with 500 iterations.

The current code has two copies of the device name, ibdev->dev and
dev_name(&ibdev->dev), and they are setup at different times, which is
very confusing.
Set them both up at the same time and make dev_name() the lead name, which
is the proper use of the driver core APIs. To make it very clear that the
name is not valid until registration pass it in to the
ib_register_device() call rather than messing with ibdev->name directly.
Also the reorganization now checks that dev_name is unique even if it does
not contain a %.

Noticed while reviewing commit d4b4dd1b9706 ("RDMA/umem: Do not use
current->tgid to track the mm_struct") patch. Why would we take a lock,
adjust a protected variable, drop the lock, and *then* check the input
into our protected variable adjustment? Then we have to take the lock
again on our error unwind. Let's just check the input early and skip
taking the locks needlessly if the input isn't valid.
It was also noticed that we set mm = current->mm, we then never modify
mm, but we still go back and reference current->mm a number of times
needlessly. Be consistent in using the stored reference in mm.

Currently add_modify_gid() for IB link layer has followong issue

When GID update event occurs, core releases reference to the GID

This is incorrect.
GID entry state and entry pointer is provides the accurate GID enty
state. Such fields must be updated with rwlock to protect against
readers and, such fields must be in sane state before refcount can drop
to zero. Otherwise above race condition can happen leading to
use-after-free situation.
Following backtrace has been observed when cache update for an IB port
is triggered while IPoIB ULP is creating an AH.
Therefore, when updating GID entry, first mark a valid entry as invalid
through state and set the barrier so that no callers can acquired
the GID entry, followed by release reference to it.
