51fe0a4705 net: ethernet: mvpp2_main: fix possible OOB write in mvpp2_ethtool_get_rxnfc()
rules is allocated in ethtool_get_rxnfc and the size is determined by
rule_cnt from user space. So rule_cnt needs to be check before using
rules to avoid OOB writing or NULL pointer dereference.

88e69af061 octeontx2-pf: Fix page pool cache index corruption.
The access to page pool `cache' array and the `count' variable
is not locked. Page pool cache access is fine as long as there
is only one consumer per pool.

octeontx2 driver fills in rx buffers from page pool in NAPI context.
If system is stressed and could not allocate buffers, refiiling work
will be delegated to a delayed workqueue. This means that there are
two cosumers to the page pool cache.

Either workqueue or IRQ/NAPI can be run on other CPU. This will lead
to lock less access, hence corruption of cache pool indexes.

To fix this issue, NAPI is rescheduled from workqueue context to refill
rx buffers.

29fe7a1b62 octeontx2-af: Fix truncation of smq in CN10K NIX AQ enqueue mbox handler
The smq value used in the CN10K NIX AQ instruction enqueue mailbox
handler was truncated to 9-bit value from 10-bit value because of
typecasting the CN10K mbox request structure to the CN9K structure.
Though this hasn't caused any problems when programming the NIX SQ
context to the HW because the context structure is the same size.
However, this causes a problem when accessing the structure parameters.
This patch reads the right smq value for each platform.

597d0ec0e4 cteonxt2-pf: Fix backpressure config for multiple PFC priorities to work simultaneously
MAC (CGX or RPM) asserts backpressure at TL3 or TL2 node of the egress
hierarchical scheduler tree depending on link level config done. If
there are multiple PFC priorities enabled at a time and for all such
flows to backoff, each priority will have to assert backpressure at
different TL3/TL2 scheduler nodes and these flows will need to submit
egress pkts to these nodes.

Current PFC configuration has an issue where in only one backpressure
scheduler node is being allocated which is resulting in only one PFC
priority to work. This patch fixes this issue.

49fa4b0d06 octeontx2-pf: fix page_pool creation fail for rings > 32k
octeontx2 driver calls page_pool_create() during driver probe()
and fails if queue size > 32k. Page pool infra uses these buffers
as shock absorbers for burst traffic. These pages are pinned down
over time as working sets varies, due to the recycling nature
of page pool, given page pool (currently) don't have a shrinker
mechanism, the pages remain pinned down in ptr_ring.
Instead of clamping page_pool size to 32k at
most, limit it even more to 2k to avoid wasting memory.

This have been tested on octeontx2 CN10KA hardware.
TCP and UDP tests using iperf shows no performance regressions.

758c910781 octeon_ep: cancel queued works in probe error path
If it fails to get the devices's MAC address, octep_probe exits while
leaving the delayed work intr_poll_task queued. When the work later
runs, it's a use after free.

Move the cancelation of intr_poll_task from octep_remove into
octep_device_cleanup. This does not change anything in the octep_remove
flow, but octep_device_cleanup is called also in the octep_probe error
path, where the cancelation is needed.

Note that the cancelation of ctrl_mbox_task has to follow
intr_poll_task's, because the ctrl_mbox_task may be queued by
intr_poll_task.

Better cancel it after the netdev is unregistered.
It's harmless for octep_tx_timeout_task to run in the window between the

and results in a non offloaded route:

    $ ip route
    10.0.0.0/24 dev swp5 proto kernel scope link src 10.0.0.1 rt_trap
    10.0.1.0/24 nhid 20 via 10.0.0.2 dev swp5 rt_trap

When creating a route referencing a nexthop via its ID, the nexthop will
be stored in a separate nh pointer instead of the array of nexthops in
the fib_info struct. This causes issues since fib_info_nh() only handles
the nexthops array, but not the separate nh pointer, and will loudly
WARN about it.

In contrast fib_info_nhc() handles both, but returns a fib_nh_common
pointer instead of a fib_nh pointer. Luckily we only ever access fields
from the fib_nh_common parts, so we can just replace all instances of
fib_info_nh() with fib_info_nhc() and access the fields via their
fib_nh_common names.

This allows handling IPv4 routes with an external nexthop, and they now
get offloaded as expected:

    $ ip route
    10.0.0.0/24 dev swp5 proto kernel scope link src 10.0.0.1 rt_trap
    10.0.1.0/24 nhid 20 via 10.0.0.2 dev swp5 offload rt_offload

b755c25fbc prestera: fix fallback to previous version on same major version
When both supported and previous version have the same major version,
and the firmwares are missing, the driver ends in a loop requesting the
same (previous) version over and over again:

    [   76.327413] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.1.img firmware, fall-back to previous 4.0 version

    ...

Fix this by inverting the check to that we aren't yet at the previous
version, and also check the minor version.

This also catches the case where both versions are the same, as it was
after commit bb5dbf2cc6 ("net: marvell: prestera: add firmware v4.0
support").

With this fix applied:

3d40aed862 net: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate

As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

unlike strict priority, where number of classes are limited to max
8, there is no restriction on the number of dwrr child nodes unless
the count increases the max number of child nodes supported.

Hardware expects strict priority transmit schedular indexes mapped
to their priority. This patch adds defines transmit schedular allocation
algorithm such that the above requirement is honored.

e7002b3b20 octeontx2-pf: mcs: Generate hash key using ecb(aes)
Hardware generated encryption and ICV tags are found to
be wrong when tested with IEEE MACSEC test vectors.
This is because as per the HRM, the hash key (derived by
AES-ECB block encryption of an all 0s block with the SAK)
has to be programmed by the software in
MCSX_RS_MCS_CPM_TX_SLAVE_SA_PLCY_MEM_4X register.
Hence fix this by generating hash key in software and
configuring in hardware.

f8e343326c net: mvpp2: debugfs: remove redundant parameter check in three functions
As per the comment above debugfs_create_dir(), it is not expected to
return an error, so an extra error check is not needed.
Drop the return check of debugfs_create_dir() in
mvpp2_dbgfs_c2_entry_init(), mvpp2_dbgfs_flow_tbl_entry_init()
and mvpp2_dbgfs_cls_init().

8fcd7c7b3a octeontx2-pf: Dont allocate BPIDs for LBK interfaces
Current driver enables backpressure for LBK interfaces.
But these interfaces do not support this feature.
Hence, this patch fixes the issue by skipping the
backpressure configuration for these interfaces.
