rvt_mregion uses percpu_ref for reference counting and RCU to protect
accesses from lkey_table. When a rvt_mregion needs to be freed, it
first gets unregistered from lkey_table and then rvt_check_refs() is
called to wait for in-flight usages before the rvt_mregion is freed.
rvt_check_refs() seems to have a couple issues.
* It has a fast exit path which tests percpu_ref_is_zero(). However,
a percpu_ref reading zero doesn't mean that the object can be
released. In fact, the ->release() callback might not even have
started executing yet. Proceeding with freeing can lead to
use-after-free.
* lkey_table is RCU protected but there is no RCU grace period in the
free path. percpu_ref uses RCU internally but it's sched-RCU whose
grace periods are different from regular RCU. Also, it generally
isn't a good idea to depend on internal behaviors like this.
To address the above issues, this patch removes the fast exit and adds
an explicit synchronize_rcu().

Resolving route for RoCE for a path record is needed only for the

Therefore,

code of resolving route.
(b) Setting dlid, path bits is not needed for RoCE.
Additionally ah attribute initialization is done from the path record
entry, so it is better to refer to path record entry type for
different link layer instead of ah attribute type while initializing
ah attribute itself.

Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.

This patch fixes RDMA/rxe over 802.1q VLAN devices.
Without it, I observed the following behavior:
a) adding a VLAN device to RXE via rxe_net_add() creates a non-functional
RDMA device. This is caused by the logic in enum_all_gids_of_dev_cb() /
is_eth_port_of_netdev(), which only considers networks connected to
"upper devices" of the configured network device, resulting in an empty
set of gids for a VLAN interface that is an "upper device" itself.
Later attempts to connect via this rdma device fail in cma_acuire_dev()
because no gids can be resolved.
b) adding the master device of the VLAN device instead seems to work
initially, target addresses via VLAN devices are resolved successfully.
But the connection times out because no 802.1q VLAN headers are
inserted in the ethernet packets, which are therefore never received.
This happens because the RXE layer sends the packets via the master
device rather than the VLAN device.
The problem could be solved by changing either a) or b). My thinking was
that the logic in a) was created deliberately, thus I decided to work on
b). It turns out that the information about the VLAN interface for the gid
at hand is available in the AV information. My patch converts the RXE code
to use this netdev instead of rxe->ndev. With this change, RXE over vlan
works on my test system.

cma_port_is_unique() allows local port reuse if the quad (source
address and port, destination address and port) for this connection
is unique. However, if the destination info is zero or unspecified, it
can't make a correct decision but still allows port reuse. For example,
sometimes rdma_bind_addr() is called with unspecified destination and
reusing the port can lead to creating a connection with a duplicate quad,
after the destination is resolved. The issue manifests when MPI scale-up
tests hang after the duplicate quad is used.
Set the destination address family and add checks for zero destination
address and port to prevent source port reuse based on invalid destination.
