The mlx4 and mlx5 implemented differently the WQ input checks. Instead of
duplicating mlx4 logic in the mlx5, let's prepare the input in the central
place.
The mlx5 implementation didn't check for validity of state input. It is
not real bug because our FW checked that, but still worth to fix.

iwl-next Intel Wired LAN Driver Updates 2021-06-01
This pull request is targeting net-next and rdma-next branches.
These patches have been reviewed by netdev and rdma mailing lists[1].
This series adds RDMA support to the ice driver for E810 devices and
converts the i40e driver to use the auxiliary bus infrastructure
for X722 devices. The PCI netdev drivers register auxiliary RDMA devices
that will bind to auxiliary drivers registered by the new irdma module.

and ice_cfg_rdma_fltr() no longer return ice_status
- Remove null check from ice_aq_add_rdma_qsets()
v2:
- Added patch 'i40e: Replace one-element array with flexible-array
member'
Changes since linked review (v6):
- Removed unnecessary checks in i40e_client_device_register() and
i40e_client_device_unregister()

There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Refactor the code according to the use of a flexible-array member in struct
i40e_qvlist_info instead of one-element array, and use the struct_size()
helper.

Pull rdma updates from Jason Gunthorpe:
"This is significantly bug fixes and general cleanups. The noteworthy
new features are fairly small:
- XRC support for HNS and improves RQ operations
- Bug fixes and updates for hns, mlx5, bnxt_re, hfi1, i40iw, rxe, siw
and qib
- Quite a few general cleanups on spelling, error handling, static
checker detections, etc
- Increase the number of device ports supported beyond 255. High port
count software switches now exist
- Several bug fixes for rtrs

Core:
- bpf:
- allow bpf programs calling kernel functions (initially to

- enable task local storage for tracing programs - remove the
need to store per-task state in hash maps, and allow tracing
programs access to task local storage previously added for
BPF_LSM

walk all map elements in a more robust and easier to verify
fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection

parsing scripts we already employ for bpf-helpers
- libbpf, bpftool: support static linking of BPF ELF files
- improve support for encapsulation of L2 packets
- xdp: restructure redirect actions to avoid a runtime lookup,
improving performance by 4-8% in microbenchmarks

- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR

retpoline overhead on VLAN and TEB GRO
- use less memory for sysctls, add a new sysctl type, to allow using
u8 instead of "int" and "long" and shrink networking sysctls

In bnxt_qplib_alloc_res, it calls bnxt_qplib_alloc_dpi_tbl(). Inside
bnxt_qplib_alloc_dpi_tbl, dpit->dbr_bar_reg_iomem is freed via
pci_iounmap() in unmap_io error branch. After the callee returns err code,
bnxt_qplib_alloc_res calls
bnxt_qplib_free_res()->bnxt_qplib_free_dpi_tbl() in the fail branch. Then
dpit->dbr_bar_reg_iomem is freed in the second time by pci_iounmap().
My patch set dpit->dbr_bar_reg_iomem to NULL after it is freed by
pci_iounmap() in the first time, to avoid the double free.

Pull CFI on arm64 support from Kees Cook:
"This builds on last cycle's LTO work, and allows the arm64 kernels to
be built with Clang's Control Flow Integrity feature. This feature has
happily lived in Android kernels for almost 3 years[1], so I'm excited
to have it ready for upstream.
The wide diffstat is mainly due to the treewide fixing of mismatched
list_sort prototypes. Other things in core kernel are to address
various CFI corner cases. The largest code portion is the CFI runtime
implementation itself (which will be shared by all architectures
implementing support for CFI). The arm64 pieces are Acked by arm64
maintainers rather than coming through the arm64 tree since carrying
this tree over there was going to be awkward.
CFI support for x86 is still under development, but is pretty close.
There are a handful of corner cases on x86 that need some improvements
to Clang and objtool, but otherwise works well.

Expose a non standard query port via IOCTL that will be used to expose
port attributes that are specific to mlx5 devices.
The new interface receives a port number to query and returns a structure
that contains the available attributes for that port. This will be used
to fill the gap between pure DEVX use cases and use cases where a kernel
needs to inform userspace about various kernel driver configurations that
userspace must use in order to work correctly.
Flags is used to indicate which fields are valid on return.
MLX5_IB_UAPI_QUERY_PORT_VPORT:
The vport number of the queered port.
MLX5_IB_UAPI_QUERY_PORT_VPORT_VHCA_ID:

Currently when GID is deleted, it zero out all the fields of the RoCE
address in the SET_ROCE_ADDRESS command for a specified index.
roce_version = 0 means RoCEv1 in the SET_ROCE_ADDRESS command.
This assumes that device has RoCEv1 always enabled which is not always
correct. For example Subfunction does not support RoCEv1.
Due to this assumption a previously added RoCEv2 GID is always deleted as
RoCEv1 GID. This results in a below syndrome:
mlx5_core.sf mlx5_core.sf.4: mlx5_cmd_check:777:(pid 4256): SET_ROCE_ADDRESS(0x761) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x12822d)
Hence set the right RoCE version during GID deletion provided by the core.

Fix it by adding the chunk entry to the PBLE info list only after

Introduce and implement new UAPI to allocate address space for MEMIC
operations such as atomic. This includes:
1. Expose new IOCTL for request mapping of MEMIC operation.
2. Hold the operations address in a list, so same operation to same DM
will be allocated only once.
3. Manage refcount on the mlx5_ib_dm object, so it would be keep valid

All other users of the dummy netdevice embed the netdev in other
structures:
init_dummy_netdev(&mal->dummy_dev);
init_dummy_netdev(ð->dummy_dev);
init_dummy_netdev(&ar->napi_dev);
init_dummy_netdev(&irq_grp->napi_ndev);
init_dummy_netdev(&wil->napi_ndev);
init_dummy_netdev(&trans_pcie->napi_dev);
init_dummy_netdev(&dev->napi_dev);
init_dummy_netdev(&bus->mux_dev);
The AIP and VNIC implementation turns that model inside out and used a
kfree() to free what appears to be a netdev struct when in reality, it is
a struct that enbodies the rx state as well as the dummy netdev used to
support napi_poll across disparate receive contexts. The relationship is
infered by the odd allocation:
const int netdev_size = sizeof(*dd->dummy_netdev) +
sizeof(struct hfi1_netdev_priv);
<snip>
dd->dummy_netdev = kcalloc_node(1, netdev_size, GFP_KERNEL, dd->node);
Correct the issue by:
- Correctly naming the alloc and free functions
- Renaming hfi1_netdev_priv to hfi1_netdev_rx
- Replacing dd dummy_netdev with a netdev_rx pointer
- Embedding the net_device in hfi1_netdev_rx
- Moving the init_dummy_netdev to the alloc routine
- Adjusting wrappers to fit the new model

list_sort() internally casts the comparison function passed to it
to a different type with constant struct list_head pointers, and
uses this pointer to call the functions, which trips indirect call
Control-Flow Integrity (CFI) checking.
Instead of removing the consts, this change defines the
list_cmp_func_t type and changes the comparison function types of
all list_sort() callers to use const pointers, thus avoiding type
mismatches.

To update xlt (during mlx5_ib_reg_user_mr()), the driver can request up to
1 MB (order-8) memory, depending on the size of the MR. This costly
allocation can sometimes take very long to return (a few seconds). This
causes the calling application to hang for a long time, especially when
the system is fragmented. To avoid these long latency spikes, the calls
the higher order allocations need to fail faster in case they are not
available.
In order to acheive this we need __GFP_NORETRY flag in the gfp_mask before
during fetching the free pages. Allow the algorithm to automatically fall
back to smaller page sizes.

Current code uses many different types when dealing with a port of a RDMA
device: u8, unsigned int and u32. Switch to u32 to clean up the logic.
This allows us to make (at least) the core view consistent and use the
same type. Unfortunately not all places can be converted. Many uverbs
functions expect port to be u8 so keep those places in order not to break
UAPIs. HW/Spec defined values must also not be changed.
With the switch to u32 we now can support devices with more than 255
ports. U32_MAX is reserved to make control logic a bit easier to deal
with. As a device with U32_MAX ports probably isn't going to happen any
time soon this seems like a non issue.
When a device with more than 255 ports is created uverbs will report the
RDMA device as having 255 ports as this is the max currently supported.
The verbs interface is not changed yet because the IBTA spec limits the
port size in too many places to be u8 and all applications that relies in
verbs won't be able to cope with this change. At this stage, we are
extending the interfaces that are using vendor channel solely
Once the limitation is lifted mlx5 in switchdev mode will be able to have
thousands of SFs created by the device. As the only instance of an RDMA
device that reports more than 255 ports will be a representor device and
it exposes itself as a RAW Ethernet only device CM/MAD/IPoIB and other
ULPs aren't effected by this change and their sysfs/interfaces that are
exposes to userspace can remain unchanged.
While here cleanup some alignment issues and remove unneeded sanity
checks (mainly in rdmavt),

The umem DMA list calculation was locked at 4k pages due to confusion
around how this API works and is used when larger pages are present.
The conclusion is:
- umem's cannot extend past what is mapped into the process, so creating
a lage page size and referring to a sub-range is not allowed
- umem's must always have a page offset of zero, except for sub PAGE_SIZE
umems
- The feature of umem_offset to create multiple objects inside a umem
is buggy and isn't used anyplace. Thus we can assume all users of the
current API have umem_offset == 0 as well
Provide a new page size calculator that limits the DMA list to the VA
range and enforces umem_offset == 0.
Allow user space to specify the page sizes which it can accept, this
bitmap must be derived from the intended use of the umem, based on
per-usage HW limitations.

Now that the SRCU stuff has been removed the entire MR destroy logic can
be made a lot simpler. Currently there are many different ways to destroy a
MR and it makes it really hard to do this task correctly. Route all
destruction through mlx5_ib_dereg_mr() and make it work for all
situations.
Since it turns out all the different MR types do basically the same thing
this removes a lot of knowledge of MR internals from ODP and leaves ODP
just exporting an operation to clean up children.
This fixes a few weird corner cases bugs and firmly uses the correct
ordering of the MR destruction:
- Stop parallel access to the mkey via the ODP xarray
- Stop DMA
- Release the umem
- Clean up ODP children
- Free/Recycle the MR

The struct mlx5_ib_mr can be used for three different things, but only one
at a time:
- In the user MR cache
- As a kernel MR
- As a user MR
Overlay the three things into a single union with the following rules:
- If the mr is found on the cache_ent->head list then it is a cache MR
and umem == NULL. The entire union is zero after the MR is removed from
the cache.
- If umem != NULL or type == IB_MR_TYPE_USER then it is a user MR.
- If umem == NULL then it is a kernel MR
This reduces the size of struct mlx5_ib_mr to 552 bytes from 702.
The only place the three flows overlap in the code is during dereg, so add
a few extra checks along there.

All of the ODP code assumes when it calls mlx5_mr_cache_alloc() the ODP
related fields are zero'd. This is true if the MR was just allocated, but
if the MR is recycled through the cache then the values are never zero'd.
This causes a bug in the odp_stats, they don't reset when the MR is
reallocated, also is_odp_implicit is never 0'd.
So we can use memset on a block of the mlx5_ib_mr reorganize the structure

It is organized as an anonymous struct because the next patch will make
this a union.
Delete the unused smr_info. Don't set the kernel only desc_size on the

1. Don't set the ts_format bit to default when it reserved - device is
running in the old mode (free running).
2. XRC doesn't have a CQ therefore the ts format in the QP
context should be default / free running.
3. Set ts_format to WQ.

Merged to resolve conflicts with RDMA rc commits
- drivers/infiniband/sw/rxe/rxe_net.c
The final logic is to call rxe_get_dev_from_net() again with the master
netdev if the packet was rx'd on a vlan. To keep the elimination of the

RDMA/mlx5: Fail QP creation if the device can not support the CQE TS
net/mlx5: Add new timestamp mode bits
In ConnectX6Dx device, HW can work in real time timestamp mode according
to the device capabilities per RQ/SQ/QP.
When the flag IB_UVERBS_CQ_FLAGS_TIMESTAMP_COMPLETION is set, the user
expect to get TS on the CQEs in free running format, so we need to fail
the QP creation if the current mode of the device doesn't support it.

The traditional DevX CQ creation flow goes through mlx5_core_create_cq()
which checks that the given EQN corresponds to an existing EQ and attaches
a devx handler to the EQN for the CQ.
In some cases the EQ will not be a kernel EQ, but will be controlled by
modify CQ, don't block creating these just because the EQN can't be found
in the kernel.

The register 0x07014 is actually the head pointer of CMDQ, and 0x07010
means tail pointer. Current definitions are confusing, so rename them and
related variables.
The next_to_use of structure hns_roce_v2_cmq_ring has the same semantics
as head, merge them into one member. The next_to_clean of structure
hns_roce_v2_cmq_ring has the same semantics as tail. After deleting
next_to_clean, tail should also be deleted.

CMDQ works serially, after each successful transmission, the head and tail
pointers will be equal, so there is no need to check whether the queue is
full. At the same time, since the descriptor of each transmission is new,
there is no need to perform a cleanup operation. Then, the field named
next_to_clean in structure hns_roce_v2_cmq_ring is redundant.
