Roger Quadros says:
====================
net: ethernet: ti: am65-cpsw: Fixes to multi queue RX feature
On J7 platforms, setting up multiple RX flows was failing
as the RX free descriptor ring 0 is shared among all flows
and we did not allocate enough elements in the RX free descriptor
ring 0 to accommodate for all RX flows. Patch 1 fixes this.
The second patch fixes a warning if there was any error in
am65_cpsw_nuss_init_rx_chns() and am65_cpsw_nuss_cleanup_rx_chns()
was called after that.

flow->irq is initialized to 0 which is a valid IRQ. Set it to -EINVAL
in error path of am65_cpsw_nuss_init_rx_chns() so we do not try
to free an unallocated IRQ in am65_cpsw_nuss_remove_rx_chns().
If user tried to change number of RX queues and am65_cpsw_nuss_init_rx_chns()
failed due to any reason, the warning will happen if user tries to change
the number of RX queues after the error condition.

On J7 platforms, setting up multiple RX flows was failing
as the RX free descriptor ring 0 is shared among all flows
and we did not allocate enough elements in the RX free descriptor
ring 0 to accommodate for all RX flows.
This issue is not present on AM62 as separate pair of
rings are used for free and completion rings for each flow.
Fix this by allocating enough elements for RX free descriptor
ring 0.
However, we can no longer rely on desc_idx (descriptor based
offsets) to identify the pages in the respective flows as
free descriptor ring includes elements for all flows.
To solve this, introduce a new swdata data structure to store
flow_id and page. This can be used to identify which flow (page_pool)
and page the descriptor belonged to when popped out of the
RX rings.

Rick reported that his Pluggable USB4 dock does not work anymore after
upgrading to v6.10 kernel.
It looks like commit c6ca1ac9f472 ("thunderbolt: Increase sideband
access polling delay") makes the device router enumeration happen later
than what might be expected by the dock (although there is no such limit
in the USB4 spec) which probably makes it assume there is something
wrong with the high-speed link and reset it. After the link is reset the
same issue happens again and again.
For this reason lower the sideband access delay from 5ms to 1ms. This
seems to work fine according to Rick's testing.

Fix an issue detected by the Smatch tool:
sound/soc/bcm/bcm63xx-pcm-whistler.c:264 i2s_dma_isr()
error: uninitialized symbol 'val_1'.
sound/soc/bcm/bcm63xx-pcm-whistler.c:264 i2s_dma_isr()
error: uninitialized symbol 'val_2'.
These errors were triggered because the variables 'val_1' and 'val_2'
could remain uninitialized if 'offlevel' is zero, meaning the loop
that assigns values to them does not execute. In this case,
'dma_addr_next' would use uninitialized data, potentially leading
to undefined behavior.
To resolve this, a conditional update for 'dma_addr_next' is added,
ensuring it is assigned only when 'val_1' and 'val_2' are read.
A new boolean variable 'val_read' flags when the values have been
retrieved, setting 'dma_addr_next' only if valid data is available.
This solution prevents the use of uninitialized data, maintaining
defined behavior for 'dma_addr_next' in all cases, and aligns with
expected usage of I2S RX descriptor data.

An atomicity violation occurs when the validity of the variables
da7219->clk_src and da7219->mclk_rate is being assessed. Since the entire
assessment is not protected by a lock, the da7219 variable might still be
in flux during the assessment, rendering this check invalid.
To fix this issue, we recommend adding a lock before the block
if ((da7219->clk_src == clk_id) && (da7219->mclk_rate == freq)) so that
the legitimacy check for da7219->clk_src and da7219->mclk_rate is
protected by the lock, ensuring the validity of the check.
This possible bug is found by an experimental static analysis tool
developed by our team. This tool analyzes the locking APIs
to extract function pairs that can be concurrently executed, and then
analyzes the instructions in the paired functions to identify possible
concurrency bugs including data races and atomicity violations.

When the driver is uninstalled and the VF is disabled concurrently, a
kernel crash occurs. The reason is that the two actions call function
pci_disable_sriov(). The num_VFs is checked to determine whether to
release the corresponding resources. During the second calling, num_VFs
is not 0 and the resource release function is called. However, the
corresponding resource has been released during the first invoking.
Therefore, the problem occurs:

The RTC update work involves runtime resuming the UFS controller. Hence,
only start the RTC update work after runtime power management in the UFS

Pull SoC fixes from Arnd Bergmann:
"Where the last set of fixes was mostly drivers, this time the
devicetree changes all come at once, targeting mostly the Rockchips,
Qualcomm and NXP platforms.
The Qualcomm bugfixes target the Snapdragon X Elite laptops,
specifically problems with PCIe and NVMe support to improve
reliability, and a boot regresion on msm8939.
Also for Snapdragon platforms, there are a number of correctness
changes in the several platform specific device drivers, but none of
these are as impactful.
On the NXP i.MX platform, the fixes are all for 64-bit i.MX8 variants,
correcting individual entries in the devicetree that were incorrect
and causing the media, video, mmc and spi drivers to misbehave in
minor ways.
The Arm SCMI firmware driver gets fixes for a use-after-free bug and
for correctly parsing firmware information.
On the RISC-V side, there are three minor devicetree fixes for
starfive and sophgo, again addressing only minor mistakes. One device
driver patch fixes a problem with spurious interrupt handling"

If Client send simultaneous SMB operations to ksmbd, It exhausts too much
memory through the "ksmbd_work_cache”. It will cause OOM issue.
ksmbd has a credit mechanism but it can't handle this problem. This patch
add the check if it exceeds max credits to prevent this problem by assuming
that one smb request consumes at least one credit.

Commit 929ebc93ccaa ("cpufreq: intel_pstate: Set asymmetric CPU
capacity on hybrid systems") overlooked a corner case in which some
CPUs may be offline to start with and brought back online later,
after the intel_pstate driver has been registered, so their asymmetric
capacity will not be set.
Address this by calling hybrid_update_capacity() in the CPU
initialization path that is executed instead of the online path
for those CPUs.
Note that this asymmetric capacity update will be skipped during
driver initialization and mode switches because hybrid_max_perf_cpu
is NULL in those cases.

Modify intel_pstate_register_driver() to clear hybrid_max_perf_cpu
before calling cpufreq_register_driver(), so that asymmetric CPU
capacity scaling is not updated until hybrid_init_cpu_capacity_scaling()
runs down the road. This is done in preparation for a subsequent
change adding asymmetric CPU capacity computation to the CPU init path
to handle CPUs that are initially offline.
The information on whether or not hybrid_max_perf_cpu was NULL before
it has been cleared is passed to hybrid_init_cpu_capacity_scaling(),
so full initialization of CPU capacity scaling can be skipped if it
has been carried out already.
No intentional functional impact.

The code currently uses list_for_each_entry_rcu() while holding an SRCU
lock, triggering false positive warnings with CONFIG_PROVE_RCU=y
enabled:
drivers/nvme/host/core.c:3770 RCU-list traversed in non-reader section!!
While the list is properly protected by SRCU lock, the code uses the wrong
list traversal primitive. Replace list_for_each_entry_rcu() with
list_for_each_entry_srcu() to correctly indicate SRCU-based protection
and eliminate the false warning.

This is a partial revert to commit 76a0a3f9cc2f ("e1000e: fix force smbus
during suspend flow"). That commit fixed a sporadic PHY access issue but
introduced a regression in runtime suspend flows.
The original issue on Meteor Lake systems was rare in terms of the
reproduction rate and the number of the systems affected.
After the integration of commit 0a6ad4d9e169 ("e1000e: avoid failing the
system during pm_suspend"), PHY access loss can no longer cause a
system-level suspend failure. As it only occurs when the LAN cable is
disconnected, and is recovered during system resume flow. Therefore, its
functional impact is low, and the priority is given to stabilizing
runtime suspend.

Fix a race condition in the i40e driver that leads to MAC/VLAN filters
becoming corrupted and leaking. Address the issue that occurs under
heavy load when multiple threads are concurrently modifying MAC/VLAN
filters by setting mac and port VLAN.
1. Thread T0 allocates a filter in i40e_add_filter() within
i40e_ndo_set_vf_port_vlan().
2. Thread T1 concurrently frees the filter in __i40e_del_filter() within
i40e_ndo_set_vf_mac().
3. Subsequently, i40e_service_task() calls i40e_sync_vsi_filters(), which
refers to the already freed filter memory, causing corruption.
Reproduction steps:
1. Spawn multiple VFs.
2. Apply a concurrent heavy load by running parallel operations to change
MAC addresses on the VFs and change port VLANs on the host.
3. Observe errors in dmesg:
"Error I40E_AQ_RC_ENOSPC adding RX filters on VF XX,
please set promiscuous on manually for VF XX".
Exact code for stable reproduction Intel can't open-source now.
The fix involves implementing a new intermediate filter state,
I40E_FILTER_NEW_SYNC, for the time when a filter is on a tmp_add_list.
These filters cannot be deleted from the hash list directly but
must be removed using the full process.

In an event where the platform running the device control plane
is rebooted, reset is detected on the driver. It releases
all the resources and waits for the reset to complete. Once the
reset is done, it tries to build the resources back. At this
time if the device control plane is not yet started, then
the driver timeouts on the virtchnl message and retries to
establish the mailbox again.
In the retry flow, mailbox is deinitialized but the mailbox
workqueue is still alive and polling for the mailbox message.
This results in accessing the released control queue leading to
null-ptr-deref. Fix it by unrolling the work queue cancellation
and mailbox deinitialization in the reverse order which they got
initialized.

When the device control plane is removed or the platform
running device control plane is rebooted, a reset is detected
on the driver. On driver reset, it releases the resources and
waits for the reset to complete. If the reset fails, it takes
the error path and releases the vport lock. At this time if the
monitoring tools tries to access link settings, it call traces
for accessing released vport pointer.
To avoid it, move link_speed_mbps to netdev_priv structure
which removes the dependency on vport pointer and the vport lock
in idpf_get_link_ksettings. Also use netif_carrier_ok()
to check the link status and adjust the offsetof to use link_up
instead of link_speed_mbps.

Fix Flow Director not allowing to re-map traffic to 0th queue when action
is configured to drop (and vice versa).
The current implementation of ethtool callback in the ice driver forbids
change Flow Director action from 0 to -1 and from -1 to 0 with an error,
e.g:
# ethtool -U eth2 flow-type tcp4 src-ip 1.1.1.1 loc 1 action 0
# ethtool -U eth2 flow-type tcp4 src-ip 1.1.1.1 loc 1 action -1
rmgr: Cannot insert RX class rule: Invalid argument
We set the value of `u16 q_index = 0` at the beginning of the function
ice_set_fdir_input_set(). In case of "drop traffic" action (which is
equal to -1 in ethtool) we store the 0 value. Later, when want to change
traffic rule to redirect to queue with index 0 it returns an error
caused by duplicate found.
Fix this behaviour by change of the type of field `q_index` from u16 to s16
in `struct ice_fdir_fltr`. This allows to store -1 in the field in case
of "drop traffic" action. What is more, change the variable type in the
function ice_set_fdir_input_set() and assign at the beginning the new
`#define ICE_FDIR_NO_QUEUE_IDX` which is -1. Later, if the action is set
to another value (point specific queue index) the variable value is
overwritten in the function.

Unloading the ice driver while switchdev port representors are added to
a bridge can lead to kernel panic. Reproducer:
modprobe ice
devlink dev eswitch set $PF1_PCI mode switchdev
ip link add $BR type bridge
ip link set $BR up
echo 2 > /sys/class/net/$PF1/device/sriov_numvfs
sleep 2
ip link set $PF1 master $BR
ip link set $VF1_PR master $BR
ip link set $VF2_PR master $BR
ip link set $PF1 up
ip link set $VF1_PR up
ip link set $VF2_PR up
ip link set $VF1 up
rmmod irdma ice
When unloading the driver, ice_eswitch_detach() is eventually called as
part of VF freeing. First, it removes a port representor from xarray,
then unregister_netdev() is called (via repr->ops.rem()), finally
representor is deallocated. The problem comes from the bridge doing its
own deinit at the same time. unregister_netdev() triggers a notifier
chain, resulting in ice_eswitch_br_port_deinit() being called. It should
set repr->br_port = NULL, but this does not happen since repr has
already been removed from xarray and is not found. Regardless, it
finishes up deallocating br_port. At this point, repr is still not freed
and an fdb event can happen, in which ice_eswitch_br_fdb_event_work()
takes repr->br_port and tries to use it, which causes a panic (use after
free).
Note that this only happens with 2 or more port representors added to
the bridge, since with only one representor port, the bridge deinit is
slightly different (ice_eswitch_br_port_deinit() is called via
ice_eswitch_br_ports_flush(), not ice_eswitch_br_port_unlink()).

A workaround is available: brctl setageing $BR 0, which stops the bridge
from adding fdb entries altogether.
Change the order of operations in ice_eswitch_detach(): move the call to
unregister_netdev() before removing repr from xarray. This way
repr->br_port will be correctly set to NULL in
ice_eswitch_br_port_deinit(), preventing a panic.

When sealing or unsealing a key blob we currently do not wait for
the AEAD cipher operation to finish and simply return after submitting
the request. If there is some load on the system we can exit before
the cipher operation is done and the buffer we read from/write to
is already removed from the stack. This will e.g. result in NULL
pointer dereference errors in the DCP driver during blob creation.
Fix this by waiting for the AEAD cipher operation to finish before
resuming the seal and unseal calls.

This issue was also reported by syzbot.
It can be reproduced by following these steps(more details [1]):
1. Obtain more than 32 inputs that have similar hashes, which ends with the
pattern '0xxxxxxxe6'.
2. Reboot and add the keys obtained in step 1.
The reproducer demonstrates how this issue happened:
1. In the search_nested_keyrings function, when it iterates through the
slots in a node(below tag ascend_to_node), if the slot pointer is meta
and node->back_pointer != NULL(it means a root), it will proceed to
descend_to_node. However, there is an exception. If node is the root,
and one of the slots points to a shortcut, it will be treated as a
keyring.
2. Whether the ptr is keyring decided by keyring_ptr_is_keyring function.
However, KEYRING_PTR_SUBTYPE is 0x2UL, the same as
ASSOC_ARRAY_PTR_SUBTYPE_MASK.
3. When 32 keys with the similar hashes are added to the tree, the ROOT
has keys with hashes that are not similar (e.g. slot 0) and it splits
NODE A without using a shortcut. When NODE A is filled with keys that
all hashes are xxe6, the keys are similar, NODE A will split with a
shortcut. Finally, it forms the tree as shown below, where slot 6 points
to a shortcut.
NODE A
+------>+---+
ROOT | | 0 | xxe6
+---+ | +---+
xxxx | 0 | shortcut : : xxe6
+---+ | +---+
xxe6 : : | | | xxe6
+---+ | +---+
| 6 |---+ : : xxe6
+---+ +---+
xxe6 : : | f | xxe6
+---+ +---+
xxe6 | f |
+---+
4. As mentioned above, If a slot(slot 6) of the root points to a shortcut,
it may be mistakenly transferred to a key*, leading to a read
out-of-bounds read.
To fix this issue, one should jump to descend_to_node if the ptr is a
shortcut, regardless of whether the node is root or not.

The previous code cleanup made a variable not really used, which now
leads to a compile warning. Let's fix it.

Correct the workload setting in order not to mix the setting
with the end user. Update the workload mask accordingly.
v2: changes as below:
1. the end user can not erase the workload from driver except default workload.
2. always shows the real highest priority workoad to the end user.
3. the real workload mask is combined with driver workload mask and end user workload mask.
v3: apply this to the other ASICs as well.
v4: simplify the code
v5: refine the code based on the review comments.
