One of the pool APIs for when caller is holding lock was not defined but

rxe_pool.c uses the field pool->state to mark a pool as invalid when it is
shut down and checks it in several pool APIs to verify that the pool has
not been shut down. This is unneeded because the pools are not marked
invalid unless the entire driver is being removed at which point no
functional APIs should or could be executing. This patch removes this
field and associated code.

rxe_pool.c takes references to the pool and ib_device structs for each
object allocated and also keeps an atomic num_elem count in each
pool. This is more work than is needed. Pool allocation is only called
from verbs APIs which already have references to ib_device and pools are
only diasbled when the driver is removed so no protection of the pool
addresses are needed. The elem count is used to warn if elements are still
present in a pool when it is cleaned up which is useful.
This patch eliminates the references to the ib_device and pool structs.

rxe_alloc() used the RXE_POOL_ATOMIC flag in rxe_type_info to select
GFP_ATOMIC in calls to kzalloc(). This was intended to handle cases where
an object could be created in interrupt context. This no longer occurs
since allocating those objects has moved into the core so this flag is not
necessary. An incorrect use of this flag was still present for rxe_mc_elem
objects and is removed.

A recent patch which added an 'unlocked' version of rxe_alloc introduced a
bug causing kzalloc(..., GFP_KERNEL) to be called while holding a spin
lock. This patch corrects that error.
rxe_alloc_nl() should always be called while holding the pool->pool_lock
so the 2nd argument to kzalloc there should be GFP_ATOMIC.
rxe_alloc() prior to the change only locked the code around checking that
pool->state is RXE_POOL_STATE_VALID to avoid races between working threads
and a thread shutting down the rxe driver. This patch reverts rxe_alloc()
to this behavior so the lock is not held when kzalloc() is called.

The cited commit disallowed creating any QP which isn't raw ethernet, reg
umr or the special UD qp for testing WC, this proved too strict.
While modify can't be done (no GIDS/GID table for example) just creating a
QP is okay.
This patch partially reverts the bellow mentioned commit and places the
restriction at the modify QP stage and not at the creation. DEVX commands
should be used to manipulate such QPs.

An INI QP doesn't require receive CQ, the creation flow sets the recv counts
to zero:
if (cmd->qp_type == IB_QPT_XRC_INI) {
cmd->max_recv_wr = 0;
cmd->max_recv_sge = 0;
The new IOCTL path also does not set the rcq, so make things the same.

Dma-buf is a standard cross-driver buffer sharing mechanism that can be
used to support peer-to-peer access from RDMA devices.
Device memory exported via dma-buf is associated with a file descriptor.
This is passed to the user space as a property associated with the buffer
allocation. When the buffer is registered as a memory region, the file
descriptor is passed to the RDMA driver along with other parameters.
Implement the common code for importing dma-buf object and mapping dma-buf
pages.

This reverts commit b2d2440430.
It's true that creating rxe on top of 802.1q interfaces doesn't work.
Thus, commit fd49ddaf7e ("RDMA/rxe: prevent rxe creation on top of vlan
interface") was absolutely correct.
But b2d2440430 was incorrect assuming that with this change, RDMA and
VLAN don't work togehter at all. It just has to be set up
differently. Rather than creating rxe on top of the VLAN interface, rxe
must be created on top of the physical interface. RDMA then works just
fine through VLAN interfaces on top of that physical interface, via the
"upper device" logic.
This is hard to see in the rxe logic because it never talks about vlan,
but instead rxe carefully selects upper vlan netdevices when working with
packets which in turn imply certain vlan tagging. This is all done
correctly and interacts with the gid table with VLAN support the same as
real HW does.
b2d2440430 broke this setup deliberately and should thus be
reverted. Also, b2d2440430 removed rxe_dma_device(), so adapt the revert
to discard that hunk.
Fixes: b2d2440430 ("RDMA/rxe: Remove VLAN code leftovers from RXE")

In commit e28bf1f03b ("RDMA: Convert various random sprintf sysfs _show
uses to sysfs_emit") I mistakenly used len = sysfs_emit_at to overwrite
the last trailing space of potentially multiple entry output.
Instead use a more common style by removing the trailing space from the
output formats and adding a prefixing space to the contination formats and
converting the final terminating output newline from the defective
len = sysfs_emit_at(buf, len, "\n");
to the now appropriate and typical
len += sysfs_emit_at(buf, len, "\n");

This reverts commit fbdd0049d9.
Due to commit in fixes tag, netdevice events were received only in one net
namespace of mlx5_core_dev. Due to this when netdevice events arrive in
net namespace other than net namespace of mlx5_core_dev, they are missed.
This results in empty GID table due to RDMA device being detached from its
net device.
Hence, revert back to receive netdevice events in all net namespaces to
restore back RDMA functionality in non init_net net namespace. The
deadlock will have to be addressed in another patch.

Fix a race in rxe_mcast.c that occurs when two QPs try at the same time to
attach a multicast address. Both QPs lookup the mgid address in a pool of
multicast groups and if they do not find it create a new group elem.
Fix this by locking the lookup/alloc/add key sequence and using the
unlocked APIs added in this patch set.

The existing pool APIs use the rw_lock pool_lock to protect critical
sections that change the pool state. This does not correctly implement a
typical sequence like the following
elem = <lookup key in pool>
if found use elem else
elem = <alloc new elem in pool>
<add key to elem>
Which is racy if multiple threads are attempting to perform this at the
same time. We want the second thread to use the elem created by the first
thread not create two equivalent elems.
This patch adds new APIs that are the same as existing APIs but do not
take the pool_lock. A caller can then take the lock and perform a sequence
of pool operations and then release the lock.

The destruction flow is very complicated here because the cm_id can be
destroyed from the event handler at any time if the device is
hot-removed. This leaves behind a partial ctx with no cm_id in the
xarray, and will let user space leak memory.
Make everything consistent in this flow in all places:
- Return the xarray back to XA_ZERO_ENTRY before beginning any
destruction. The thread that reaches this first is responsible to
kfree, everyone else does nothing.
- Test the xarray during the special hot-removal case to block the
queue_work, this has much simpler locking and doesn't require a
'destroying'
- Fix the ref initialization so that it is only positive if cm_id !=
NULL, then rely on that to guide the destruction process in all cases.
Now the new ucma_destroy_private_ctx() can be called in all places that
want to free the ctx, including all the error unwinds, and none of the
details are missed.

Previously the rnbd client requested the rtrs to allocate rnbd_iu
just after the rtrs_iu. So the rnbd client passes the size of
rnbd_iu for rtrs_clt_open() and rtrs creates an array of
rnbd_iu and rtrs_iu.
For IO handling, rnbd_iu exists after the request because we pass
the size of rnbd_iu when setting the tag-set. Therefore we do not
use the rnbd_iu allocated by rtrs for IO handling.
We only use the rnbd_iu allocated by rtrs when doing session
initialization. Almost all rnbd_iu allocated by rtrs are wasted.
By this patch the rnbd client does not request rnbd_iu allocation
to rtrs but allocate it for itself when doing session initialization.
Also remove unused rtrs_permit_to_pdu from rtrs.

There is no need to get queue number repeatly for different queues from an
AEQE entity, as they are the same. Furthermore, redefine the AEQE

hardware never reports this event.
