Since rtase_init_ring, which is called within rtase_sw_reset, adds ring
entries already present in the ring list back into the list, it causes
the ring list to form a cycle. This results in list_for_each_entry_safe
failing to find an endpoint during traversal, leading to an error.
Therefore, it is necessary to remove the previously added ring_list nodes
before calling rtase_init_ring.

When validation on the backup slave is enabled, we need to validate the
Neighbor Solicitation (NS) messages received on the backup slave. To
receive these messages, the correct destination MAC address must be added
to the slave. However, the target in bonding is a unicast address, which
we cannot use directly. Instead, we should first convert it to a
Solicited-Node Multicast Address and then derive the corresponding MAC
address.
Fix the incorrect MAC address setting on both slave_set_ns_maddr() and
slave_set_ns_maddrs(). Since the two function names are similar. Add
some description for the functions. Also only use one mac_addr variable
in slave_set_ns_maddr() to save some code and logic.
Fixes: 8eb36164d1a6 ("bonding: add ns target multicast address to slave device")

This is to prepare for native XDP support.
The page pool API is more faster in allocating pages than
__alloc_skb(). Drawback is that it works at PAGE_SIZE granularity
so we are not efficient in memory usage.
i.e. we are using PAGE_SIZE (4KB) memory for 1.5KB max packet size.

Corrected the bit size calculation in the for_each_set_bit macro in
the iwl_dbgfs_tas_get_status_read(). The previous implementation used
sizeof(dyn_status), which only accounts for the number of bytes.
This has been updated to TAS_DYNA_STATUS_MAX to ensure the loop iterates
over the correct number of valid bits in dyn_status.

The FW is now responsible of determining the SMPS mode.
If the user disabled power save in a certain vif, we send the vif-level
power command to clear out the POWER_FLAGS_POWER_MANAGEMENT_ENA_MSK bit
for that vif.
But erroneously, the FW checks DEVICE_POWER_FLAGS_POWER_SAVE_ENA_MSK in
the device-level command to determine the SMPS mode.
To W/A this, send also the device-level command when the power save of a
vif changes, and disable power save if there is any vif that has power
save disabled.

The order of actions taken for debug was implemented incorrectly.
Now we implemented the dump split and do the FW reset only in the
middle of the dump (rather than the FW killing itself on error.)
As a result, some of the actions taken when applying the config
will now crash the device, so we need to fix the order.

The ioread/iowrite functions on sh only do memory mapped I/O like the
generic verion, and never map onto non-MMIO inb/outb variants, so they
just add complexity. In particular, the use of asm-generic/iomap.h
ties the declaration to the x86 implementation.
Remove the custom versions and use the architecture-independent fallback
code instead. Some of the calling conventions on sh are different here,
so fix that by adding 'volatile' keywords where required by the generic
implementation and change the cpg clock driver to no longer depend on
the interesting choice of return types for ioread8/ioread16/ioread32.

The handling of the MST Connection Status Notify message is skipped if
the probing of the topology is still pending. Acquiring the
drm_dp_mst_topology_mgr::probe_lock for this in
drm_dp_mst_handle_up_req() is problematic: the task/work this function
is called from is also responsible for handling MST down-request replies
(in drm_dp_mst_handle_down_rep()). Thus drm_dp_mst_link_probe_work() -
holding already probe_lock - could be blocked waiting for an MST
down-request reply while drm_dp_mst_handle_up_req() is waiting for
probe_lock while processing a CSN message. This leads to the probe
work's down-request message timing out.
A scenario similar to the above leading to a down-request timeout is
handling a CSN message in drm_dp_mst_handle_conn_stat(), holding the
probe_lock and sending down-request messages while a second CSN message
sent by the sink subsequently is handled by drm_dp_mst_handle_up_req().
Fix the above by moving the logic to skip the CSN handling to
drm_dp_mst_process_up_req(). This function is called from a work
(separate from the task/work handling new up/down messages), already
holding probe_lock. This solves the above timeout issue, since handling
of down-request replies won't be blocked by probe_lock.

Geert Uytterhoeven <geert+renesas@glider.be> says:
Hi all,
Initialization of the UFS controller on R-Car S4-8 ES1.0 requires only
static values. However, other UFS controller variants (R-Car S4-8 ES 1.2)
require dynamic values, like those obtained from E-FUSE, and downloading
firmware.
Hence this patch series refactors the initialization code to prepare for
this, and adds support for the UFS controller on R-Car S4-8 ES1.2.
The accompanying DTS change is available at [1].
This has been tested on:
- Renesas Spider with R-Car S4-8 ES1.0 (broken before/after),
- Renesas S4 Starter Kit with R-Car S4-8 ES1.2 (works after).

because all operations are simple and can be called directly. Remove the

Since initialization of the UFS controller on R-Car S4-8 ES1.0 requires
only static values, the driver uses initialization data stored in the const
ufs_param[] array. However, other UFS controller variants (R-Car S4-8
ES1.2) require dynamic values, like those obtained from E-FUSE. Refactor
the initialization code to prepare for this.
This also reduces kernel size by almost 30 KiB.

When the queue is reset, the bnxt_alloc_one_tpa_info() is called to
allocate tpa_info for the new queue.
And then the old queue's tpa_info should be removed by the
bnxt_free_one_tpa_info(), but it is not called.
So memory leak occurs.
It adds the bnxt_free_one_tpa_info() in the bnxt_queue_mem_free().

When qstats-get operation is executed, callbacks of netdev_stats_ops
are called. The bnxt_get_queue_stats{rx | tx} collect per-queue stats
from sw_stats in the rings.
But {rx | tx | cp}_ring are allocated when the interface is up.
So, these rings are not allocated when the interface is down.
The qstats-get is allowed even if the interface is down. However,
the bnxt_get_queue_stats{rx | tx}() accesses cp_ring and tx_ring
without null check.
So, it needs to avoid accessing rings if the interface is down.
Reproducer:
ip link set $interface down
./cli.py --spec netdev.yaml --dump qstats-get
OR
ip link set $interface down
python ./stats.py

The bnxt_rx_pkt() updates ip_summed value at the end if checksum offload
is enabled.
When the XDP-MB program is attached and it returns XDP_PASS, the
bnxt_xdp_build_skb() is called to update skb_shared_info.
The main purpose of bnxt_xdp_build_skb() is to update skb_shared_info,
but it updates ip_summed value too if checksum offload is enabled.
This is actually duplicate work.
When the bnxt_rx_pkt() updates ip_summed value, it checks if ip_summed
is CHECKSUM_NONE or not.
It means that ip_summed should be CHECKSUM_NONE at this moment.
But ip_summed may already be updated to CHECKSUM_UNNECESSARY in the
XDP-MB-PASS path.
So the by skb_checksum_none_assert() WARNS about it.
This is duplicate work and updating ip_summed in the
bnxt_xdp_build_skb() is not needed.

When a queue is restarted, it sets MRU to 0 for stopping packet flow.
MRU variable is a member of vnic_info[], the first vnic_info is default
and the second is ntuple.
Only when ntuple is enabled(ethtool -K eth0 ntuple on), vnic_info for
ntuple is allocated in init logic.
The bp->nr_vnics indicates how many vnic_info are allocated.
However bnxt_queue_{start | stop}() accesses vnic_info[BNXT_VNIC_NTUPLE]
regardless of ntuple state.

The bnxt_queue_mem_alloc() is called to allocate new queue memory when
a queue is restarted.
It internally accesses rx buffer descriptor corresponding to the index.
The rx buffer descriptor is allocated and set when the interface is up
and it's freed when the interface is down.
So, if queue is restarted if interface is down, kernel panic occurs.
