Commit a0c76345e3d3 ("devlink: disallow reload operation during device
cleanup") added devlink_reload_{enable,disable}() APIs to prevent reload
operation from racing with device probe/dismantle.
After recent changes to move devlink_register() to the end of device
probe and devlink_unregister() to the beginning of device dismantle,
these races can no longer happen. Reload operations will be denied if
the devlink instance is unregistered and devlink_unregister() will block
until all in-flight operations are done.
Therefore, remove these devlink_reload_{enable,disable}() APIs.

Introduce new devlink call to set feature mask to control devlink
behavior during device initialization phase after devlink_alloc()
is already called.
This allows us to set reload ops based on device property which
is not known at the beginning of driver initialization.
For the sake of simplicity, this API lacks any type of locking and
needs to be called before devlink_register() to make sure that no
parallel access to the ops is possible at this stage.

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below.
It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.
It has been compile tested.

All kernel devlink implementations call to devlink_alloc() during
initialization routine for specific device which is used later as
a parent device for devlink_register().
Such late device assignment causes to the situation which requires us to
call to device_register() before setting other parameters, but that call
opens devlink to the world and makes accessible for the netlink users.
Any attempt to move devlink_register() to be the last call generates the
following error due to access to the devlink->dev pointer.
[ 8.758862] devlink_nl_param_fill+0x2e8/0xe50
[ 8.760305] devlink_param_notify+0x6d/0x180
[ 8.760435] __devlink_params_register+0x2f1/0x670
[ 8.760558] devlink_params_register+0x1e/0x20
The simple change of API to set devlink device in the devlink_alloc()
instead of devlink_register() fixes all this above and ensures that
prior to call to devlink_register() everything already set.

Currently when mlx4 maps the hca_core_clock page to the user space there
are read-modifiable registers, one of which is semaphore, on this page as
well as the clock counter. If user reads the wrong offset, it can modify
the semaphore and hang the device.
Do not map the hca_core_clock page to the user space unless the device has
been put in a backwards compatibility mode to support this feature.
After this patch, mlx4 core_clock won't be mapped to user space on the
majority of existing devices and the uverbs device time feature in
ibv_query_rt_values_ex() will be disabled.

Add reload limit to demand restrictions on reload actions.
Reload limits supported:
no_reset: No reset allowed, no down time allowed, no link flap and no
configuration is lost.
By default reload limit is unspecified and so no constraints on reload
actions are required.
Some combinations of action and limit are invalid. For example, driver
can not reinitialize its entities without any downtime.
The no_reset reload limit will have usecase in this patchset to
implement restricted fw_activate on mlx5.
Have the uapi parameter of reload limit ready for future support of
multiselection.

Add devlink reload action to allow the user to request a specific reload
action. The action parameter is optional, if not specified then devlink
driver re-init action is used (backward compatible).
Note that when required to do firmware activation some drivers may need
to reload the driver. On the other hand some drivers may need to reset
the firmware to reinitialize the driver entities. Therefore, the devlink
reload command returns the actions which were actually performed.
Reload actions supported are:
driver_reinit: driver entities re-initialization, applying devlink-param
and devlink-resource values.
fw_activate: firmware activate.
command examples:
$devlink dev reload pci/0000:82:00.0 action driver_reinit
reload_actions_performed:
driver_reinit
$devlink dev reload pci/0000:82:00.0 action fw_activate

Even tho mlx4_core registers the devlink ports, it's mlx4_en
and mlx4_ib which set their type. In situations where one of
the two is not built yet the machine has ports of given type
we see the devlink warning from devlink_port_type_warn() trigger.
Having ports of a type not supported by the kernel may seem
surprising, but it does occur in practice - when the unsupported
port is not plugged in to a switch anyway users are more than happy
not to see it (and potentially allocate any resources to it).
Set the type in mlx4_core if type-specific driver is not built.

With gcc, the problem is the same, but it does not warn because

Currently, user can do dump or get of param values right after the
devlink params are registered. However the driver may not be initialized
which is an issue. The same problem happens during notification
upon param registration. Allow driver to publish devlink params
whenever it is ready to handle get() ops. Note that this cannot
be resolved by init reordering, as the "driverinit" params have
to be available before the driver is initialized (it needs the param
values there).

During boot, mlx4_core sets the driverinit configuration parameters and
updates the devlink module on the initial values calling
devlink_param_driverinit_value_set().
If devlink_param_driverinit_value_set() returns an error mlx4_core
reports kernel module warning.
This caused false alarm during boot in case kernel was compiled with
CONFIG_NET_DEVLINK off.
Fix by removing warning reported in case
devlink_param_driverinit_value_set() fails.
This actually makes the function mlx4_devlink_set_init_value()
redundant to using directly devlink_param_driverinit_value_set() and so
removed.
It fixes the following kernel trace:
mlx4_core 0000:00:06.0: devlink set parameter 0 value failed (err = -95)

This parameter enables capturing region snapshot of the crspace
during critical errors. The default value of this parameter is
disabled, it can be enabled using devlink param commands.
It is possible to configure during runtime and also driver init.

Crdump allows the driver to create a snapshot of the FW PCI
crspace and health buffer during a critical FW issue.
In case of a FW command timeout, FW getting stuck or a non zero
value on the catastrophic buffer, a snapshot will be taken.
The snapshot is exposed using devlink, cr-space, fw-health
address regions are registered on init and snapshots are attached
once a new snapshot is collected by the driver.

Health buffer address is a 32 bit PCI address offset provided by
the FW. This offset is used for reading FW health debug data
located on the shared CR space. Cr space is accessible in both
driver and FW and allows for different queries and configurations.
Health buffer size is always 64B of readable data followed by a
lock which is used to block volatile CR space access.

Create initial parameters table for mlx4.
The table consists of two generic parameters and two driver-specific
parameters.
Generic:
internal_err_reset - Enable reset device on internal errors. This
parameter can be configured on mlx4 either on runtime or during driver
initialization.
max_macs - Max number of MACs per ETH port. For mlx4 this parameter
value range is between 1 and 128. This parameter can be configured on
mlx4 only during driver initialization.
Driver specific:
enable_64b_cqe_eqe - Enable 64 byte CQEs/EQEs when the FW supports it.
This parameter can be configured on mlx4 only during driver
initialization.
enable_4k_uar - Enable using 4K UAR. This parameter can be configured on
mlx4 only during driver initialization.
Register the parameters table on mlx4_init_one() and unregister on
mlx4_remove_one().

The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:
kzalloc(a * b, gfp)
with:
kcalloc(a * b, gfp)
as well as handling cases of:
kzalloc(a * b * c, gfp)
with:
kzalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kzalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kzalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

S390 bpf_jit.S is removed in net-next and had changes in 'net',
since that code isn't used any more take the removal.
TLS data structures split the TX and RX components in 'net-next',
put the new struct members from the bug fix in 'net' into the RX
part.
The 'net-next' tree had some reworking of how the ERSPAN code works in
the GRE tunneling code, overlapping with a one-line headroom
calculation fix in 'net'.
Overlapping changes in __sock_map_ctx_update_elem(), keep the bits
that read the prog members via READ_ONCE() into local variables
before using them.

Avoid exiting the function with a lingering sysfs file (if the first
call to device_create_file() fails while the second succeeds), and avoid
calling devlink_port_unregister() twice.
In other words, either mlx4_init_port_info() succeeds and returns zero, or
it fails, returns non-zero, and requires no cleanup.

Extend the boolean interpretation of msi_x module parameter
to numerical, as follows:
0 - Don't use MSI-X.
1 - Use MSI-X, driver decides the num of MSI-X irqs.
>=2 - Use MSI-X, limit number of MSI-X irqs to msi_x.
In SRIOV, this limits the number of MSI-X irqs per VF.

Pull rdma updates from Jason Gunthorpe:
"Doug and I are at a conference next week so if another PR is sent I
expect it to only be bug fixes. Parav noted yesterday that there are
some fringe case behavior changes in his work that he would like to
fix, and I see that Intel has a number of rc looking patches for HFI1
they posted yesterday.
Parav is again the biggest contributor by patch count with his ongoing
work to enable container support in the RDMA stack, followed by Leon
doing syzkaller inspired cleanups, though most of the actual fixing
went to RC.
There is one uncomfortable series here fixing the user ABI to actually
work as intended in 32 bit mode. There are lots of notes in the commit
messages, but the basic summary is we don't think there is an actual
32 bit kernel user of drivers/infiniband for several good reasons.
However we are seeing people want to use a 32 bit user space with 64
bit kernel, which didn't completely work today. So in fixing it we
required a 32 bit rxe user to upgrade their userspace. rxe users are
still already quite rare and we think a 32 bit one is non-existing.
- Fix RDMA uapi headers to actually compile in userspace and be more
complete
- Three shared with netdev pull requests from Mellanox:
* 7 patches, mostly to net with 1 IB related one at the back).
This series addresses an IRQ performance issue (patch 1),
cleanups related to the fix for the IRQ performance problem
(patches 2-6), and then extends the fragmented completion queue
support that already exists in the net side of the driver to the
ib side of the driver (patch 7).
* Mostly IB, with 5 patches to net that are needed to support the
remaining 10 patches to the IB subsystem. This series extends
the current 'representor' framework when the mlx5 driver is in
switchdev mode from being a netdev only construct to being a
netdev/IB dev construct. The IB dev is limited to raw Eth queue
pairs only, but by having an IB dev of this type attached to the
representor for a switchdev port, it enables DPDK to work on the
switchdev device.
* All net related, but needed as infrastructure for the rdma
driver
- Updates for the hns, i40iw, bnxt_re, cxgb3, cxgb4, hns drivers
- SRP performance updates
- IB uverbs write path cleanup patch series from Leon
- Add RDMA_CM support to ib_srpt. This is disabled by default. Users
need to set the port for ib_srpt to listen on in configfs in order
for it to be enabled
(/sys/kernel/config/target/srpt/discovery_auth/rdma_cm_port)
- TSO and Scatter FCS support in mlx4
- Refactor of modify_qp routine to resolve problems seen while
working on new code that is forthcoming
- More refactoring and updates of RDMA CM for containers support from
Parav
- mlx5 'fine grained packet pacing', 'ipsec offload' and 'device
memory' user API features
- Infrastructure updates for the new IOCTL interface, based on
increased usage
- ABI compatibility bug fixes to fully support 32 bit userspace on 64
bit kernel as was originally intended. See the commit messages for
extensive details
- Syzkaller bugs and code cleanups motivated by them"
