be934cca9e IB/uverbs: Add device memory registration ioctl support
Adding new ioctl method for the MR object - REG_DM_MR.

This command can be used by users to register an allocated
device memory buffer as an MR and receive lkey and rkey
to be used within work requests.

It is added as a new method under the MR object and using a new
ib_device callback - reg_dm_mr.
The command creates a standard ib_mr object which represents the
registered memory.

bee76d7ab5 IB/uverbs: Add alloc/free dm uverbs ioctl support
This change adds uverbs support for allocation/freeing
of device memory commands.

A new uverbs object is defined of type idr to represent
and track the new resource type allocation per context.

The API requires provider driver to implement 2 new ib_device
callbacks - one for allocation and one for deallocation which
return and accept (respectively) the ib_dm object which represents
the allocated memory on the device.

The support is added via the ioctl command infrastructure
only.

9b82844197 IB/uverbs: Add action_handle flow steering specification
Binding a flow_action to flow steering rule requires using a new
specification. Therefore, adding such an IB_FLOW_SPEC_ACTION_HANDLE flow
specification.

Flow steering rules could use flow_action(s) and as of that we need to
avoid deleting flow_action(s) as long as they're being used.
Moreover, when the attached rules are deleted, action_handle reference
count should be decremented. Introducing a new mechanism of flow
resources to keep track on the attached action_handle(s). Later on, this
mechanism should be extended to other attached flow steering resources
like flow counters.

2eb9beaee5 IB/uverbs: Add flow_action create and destroy verbs
A verbs application may receive and transmits packets using a data
path pipeline. Sometimes, the first stage in the receive pipeline or
the last stage in the transmit pipeline involves transforming a
packet, either in order to make it easier for later stages to process
it or to prepare it for transmission over the wire. Such transformation
could be stripping/encapsulating the packet (i.e. vxlan),
decrypting/encrypting it (i.e. ipsec), altering headers, doing some
complex FPGA changes, etc.

Some hardware could do such transformations without software data path
intervention at all. The flow steering API supports steering a
packet (either to a QP or dropping it) and some simple packet
immutable actions (i.e. tagging a packet). Complex actions, that may
change the packet, could bloat the flow steering API extensively.
Sometimes the same action should be applied to several flows.
In this case, it's easier to bind several flows to the same action and
modify it than change all matching flows.

Introducing a new flow_action object that abstracts any packet
transformation (out of a standard and well defined set of actions).
This flow_action object could be tied to a flow steering rule via a
new specification.

Currently, we support esp flow_action, which encrypts or decrypts a
packet according to the given parameters. However, we present a
flexible schema that could be used to other transformation actions tied
to flow rules.

494c5580aa IB/uverbs: Add enum attribute type to ioctl() interface
Methods sometimes need to get one attribute out of a group of
pre-defined attributes. This is an enum-like behavior. Since
this is a common requirement, we add a new ENUM attribute to the
generic uverbs ioctl() layer. This attribute is embedded in methods,
like any other attributes we currently have. ENUM attributes point to
an array of standard UVERBS_ATTR_PTR_IN. The user-space encodes the
enum's attribute id in the id field and the internal PTR_IN attr id in
the enum_data.elem_id field. This ENUM attribute could be shared by
several attributes and it can get UVERBS_ATTR_SPEC_F_MANDATORY flag,
stating this attribute must be supported by the kernel, like any other
attribute.

f2e9bfac13 RDMA/rxe: Fix uABI structure layouts for 32/64 compat
With 32 bit compilation several of the fields become misaligned here.
Fixing this is an ABI break for 32 bit rxe and it is in well used
portions of the rxe ABI.

To handle this we bump the ABI version, as expected. However the user
space driver doesn't handle it properly today, so all existing user
space continues to work.

Updated userspace will start to require the necessary kernel version.

We don't expect there to be any 32 bit users of rxe. Most likely cases,
such as ARM 32 already generally don't work because rxe does not handle
the CPU cache properly on its shared with userspace pages.

bit compiles due to implicit compiler padding.

The structs alloc_pd_uresp, create_cq_uresp and create_qp_uresp are
not padded by the compiler, but in user space the compiler pads them
due to the way the core and driver structs are concatenated. Make
this padding explicit and consistent for future sanity.

The kernel driver can already handle the user buffer being smaller
than required and copies correctly, so no compat or ABI break happens
from introducing the explicit padding.

1f7ff9d5d3 IB/uverbs: Move to new headers and make naming consistent
Use macros to make names consistent in ioctl() uAPI:
The ioctl() uAPI works with object-method hierarchy. The method part
also states which handler should be executed when this method is called
from user-space. Therefore, we need to tie method, method's id, method's
handler and the object owning this method together.
Previously, this was done through explicit developer chosen names.
This makes grepping the code harder. Changing the method's name,
method's handler and object's name to be automatically generated based
on the ids.

The headers are split in a way so they be included and used by
user-space. One header strictly contains structures that are used
directly by user-space applications, where another header is used for
internal library (i.e. libibverbs) to form the ioctl() commands.
Other header simply contains the required general command structure.

958d2c1ba3 RDMA/bnxt: Fix structure layout for bnxt_re_pd_resp
What is going on here is a bit subtle, in the kernel there is no
problem because the struct is copied using copy_from_user, so it
can safely have an 8 byte alignment, however in userspace it must
be constructed by concatenation with the ib_uverbs_alloc_pd_resp
struct. This is due to the required memory layout to execute the
command.

Since ibv_uverbs_alloc_pd_resp is only 4 bytes long, this causes
misalignment, and the user space will experience an unexpected padding.
Currently it works around this via pointer maths.

Make everything more robust by having the compiler reduce the alignment
of the struct to 4. The userspace has assertions to ensure this
works properly in all situations.

00313983cd RDMA/nldev: provide detailed CM_ID information
Implement RDMA nldev netlink interface to get detailed CM_ID information.

Because cm_id's are attached to rdma devices in various work queue
contexts, the pid and task information at restrak_add() time is sometimes
not useful.  For example, an nvme/f host connection cm_id ends up being
bound to a device in a work queue context and the resulting pid at attach
time no longer exists after connection setup.  So instead we mark all
cm_id's created via the rdma_ucm as "user", and all others as "kernel".
This required tweaking the restrack code a little.  It also required
wrapping some rdma_cm functions to allow passing the module name string.

4bb46608ed Merge branch 'k.o/for-rc' into k.o/wip/dl-for-next
There is a 14 patch series waiting to come into for-next that has a
dependecy on code submitted into this kernel's for-rc series.  So, merge
the for-rc branch into the current for-next in order to make the patch
series apply cleanly.

5d2beb576d IB/uverbs: Use __aligned_u64 for uapi headers
This has no impact on the structure layout since these structs already
have their u64s already properly aligned, but it does document that we
have this requirement for 32 bit compatibility.

5229f87efc RDMA: Do not used __packed in uapi headers
__packed is not available in linux/types.h, so we cannot use it in
the uapi headers.

The construction struct ABC {} __packed; may still compile even if
__packed is not defined, however it simply creates a variable called
__packed, and doesn't set the alignment.

All these uses of packed are on structs that already have aligned
members.

While use in hfi may indicate the struct itself is unaligned,
the use in ocrdma is on a UHW struct which should never be unaligned,
so just delete it there.
