When compiling a kernel which has both CONFIG_NET_DSA_MSCC_OCELOT_EXT
and CONFIG_MSCC_OCELOT_SWITCH enabled, the following error message will
be printed:
[ 5.266588] Error: Driver 'ocelot-switch' is already registered, aborting...
Rename the ocelot_ext.c driver to "ocelot-ext-switch" to avoid the name
duplication, and update the mfd_cell entry for its resources.

The blamed commit did not properly convert the resource start/end format
into the DEFINE_RES_MEM_NAMED() start/length format, resulting in a
resource for vsc9959_imdio_res which is much longer than expected:
$ cat /proc/iomem
1f8000000-1f815ffff : pcie@1f0000000
1f8140000-1f815ffff : 0000:00:00.5
1f8148030-1f815006f : imdio
vs (correct)
$ cat /proc/iomem
1f8000000-1f815ffff : pcie@1f0000000
1f8140000-1f815ffff : 0000:00:00.5
1f8148030-1f814803f : imdio
Luckily it's not big enough to exceed the size of the parent resource
(pci_resource_end(pdev, VSC9959_IMDIO_PCI_BAR)), and it doesn't overlap
with anything else that the Linux driver uses currently, so the larger
than expected size isn't a practical problem that I can see. Although it
is clearly wrong in the /proc/iomem output.

During the refactoring in the commit below, vsc9953_mdio_read() was
replaced with mscc_miim_read(), which has one extra step: it checks for
the MSCC_MIIM_DATA_ERROR bits before returning the result.
On T1040RDB, there are 8 QSGMII PCSes belonging to the switch, and they
are organized in 2 groups. First group responds to MDIO addresses 4-7
because QSGMIIACR1[MDEV_PORT] is 1, and the second group responds to
MDIO addresses 8-11 because QSGMIIBCR1[MDEV_PORT] is 2. I have double
checked that these values are correctly set in the SERDES, as well as
PCCR1[QSGMA_CFG] and PCCR1[QSGMB_CFG] are both 0b01.

MSCC_MIIM_DATA_ERROR bits set. The driver as introduced in commit
84705fc165 ("net: dsa: felix: introduce support for Seville VSC9953
switch") was ignoring these bits, perhaps deliberately (although
unbeknownst to me).
This is an old IP and the hardware team cannot seem to be able to help
me track down a plausible reason for these failures. I'll keep
investigating, but in the meantime, this is a direct regression which
must be restored to a working state.
The only thing I can do is keep ignoring the errors as before.

net/sched: fix action bind logic
Some actions are not handling the case where an action can be created and bound to a
filter independently. These actions are checking for parameters only passed
in the netlink message for create/change/replace, which then errors out
for valid uses like:
tc filter ... action pedit index 1
In the iproute2 side, we saw a couple of actions with their parsers
broken when passing "index 1" as the only action argument, while the kernel
side accepted it correctly. We fixed those as well.

The TC architecture allows filters and actions to be created independently.
In filters the user can reference action objects using:
tc action add action sample ... index 1

In the current code for act_sample this is broken as it checks netlink
attributes for create/update before actually checking if we are binding to an
existing action.

Warn only once since the ratelimit parameters are still

tell you all the different processes, but still gives a

Also modify the message to note that wext stops working
for future Wi-Fi 7 hardware, this is already implemented
in commit 4ca6902769 ("wifi: wireless: deny wireless

relevance to users than the fact that we'd like to have
wireless extensions deprecated.
The issue with Wi-Fi 7 is that you can now have multiple

now become per link rather than per netdev, which can't
really be handled in wireless extensions.

Even after commit 908d4bb7c5 ("qede: fix interrupt coalescing
configuration"), some entries of the coal_entry array may theoretically
be used uninitialized:
1. qede_alloc_fp_array() allocates QEDE_MAX_RSS_CNT entries for
coal_entry. The initial allocation uses kcalloc, so everything is
initialized.
2. The user sets a small number of queues (ethtool -L).
coal_entry is reallocated for the actual small number of queues.
3. The user sets a bigger number of queues.
coal_entry is reallocated bigger. The added entries are not
necessarily initialized.
In practice, the reallocations will actually keep using the originally
allocated region of memory, but we should not rely on it.
The reallocation is unnecessary. coal_entry can always have
QEDE_MAX_RSS_CNT entries.

This series provides bug fixes for mlx5 driver.
Please pull and let me know if there is any problem.
====================
The callback context for sending/receiving APDUs to/from the selected
secure element is allocated inside nfc_genl_se_io and supposed to be
eventually freed in se_io_cb callback function. However, there are several
error paths where the bwi_timer is not charged to call se_io_cb later, and
the cb_context is leaked.
The patch proposes to free the cb_context explicitly on those error paths.
At the moment we can't simply check 'dev->ops->se_io()' return value as it
may be negative in both cases: when the timer was charged and was not.

CONFIG_ICE_GNSS was added by commit c7ef8221ca ("ice: use GNSS subsystem
instead of TTY") as a way to allow the ice driver to optionally support
GNSS features without forcing a dependency on CONFIG_GNSS.
The original implementation of that commit at [1] used IS_REACHABLE. This
was rejected by Olek at [2] with the suggested implementation of
CONFIG_ICE_GNSS.
Eventually after merging, Linus reported a .config which had
CONFIG_ICE_GNSS = y when both GNSS = n and ICE = n. This confused him and
he felt that the config option was not useful, and commented about it at
[3].
CONFIG_ICE_GNSS is defined to y whenever GNSS = ICE. This results in it
being set in cases where both options are not enabled.
The goal of CONFIG_ICE_GNSS is to ensure that the GNSS support in the ice
driver is enabled when GNSS is enabled.
The complaint from Olek about the original IS_REACHABLE was due to the
required IS_REACHABLE checks throughout the ice driver code and the fact
that ice_gnss.c was compiled regardless of GNSS support.
This can be fixed in the Makefile by using ice-$(CONFIG_GNSS) += ice_gnss.o
In this case, if GNSS = m and ICE = y, we can result in some confusing
behavior where GNSS support is not enabled because its not built in. See
[4].
To disallow this, have CONFIG_ICE depend on GNSS || GNSS = n. This ensures
that we cannot enable CONFIG_ICE as builtin while GNSS is a module.
Drop CONFIG_ICE_GNSS, and replace the IS_ENABLED checks for it with

CONFIG_GNSS.
This works to ensure that GNSS support can optionally be enabled, doesn't
have an unnnecessary extra config option, and has Kbuild enforce the
dependency such that you can't accidentally enable GNSS as a module and ICE
as a builtin.

When CONFIG_NET_CLS_ACT is disabled:
../net/sched/cls_api.c:141:13: warning: 'tcf_exts_miss_cookie_base_destroy' defined but not used [-Wunused-function]
141 | static void tcf_exts_miss_cookie_base_destroy(struct tcf_exts *exts)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Due to the way the code is structured, it is possible for a definition
of tcf_exts_miss_cookie_base_destroy() to be present without actually
being used. Its single callsite is in an '#ifdef CONFIG_NET_CLS_ACT'
block but a definition will always be present in the file. The version
of tcf_exts_miss_cookie_base_destroy() that actually does something
depends on CONFIG_NET_TC_SKB_EXT, so the stub function is used in both
CONFIG_NET_CLS_ACT=n and CONFIG_NET_CLS_ACT=y + CONFIG_NET_TC_SKB_EXT=n
configurations.
Move the call to tcf_exts_miss_cookie_base_destroy() in
tcf_exts_destroy() out of the '#ifdef CONFIG_NET_CLS_ACT', so that it
always appears used to the compiler, while not changing any behavior
with any of the various configuration combinations.

Both userspace and kernelspace can pass structs with an uninitialized
'stream' field. Since the check_state() function checks for a non-zero
stream field, suddenly these calls will fails with -EINVAL.
So check in the wrapper functions in v4l2-subdev.c (which are used by both
the kernel and userspace API) if V4L2_SUBDEV_FL_STREAMS is set, and if not,
then zero the stream field.
Currently no drivers set V4L2_SUBDEV_FL_STREAMS, so the stream field will
always be set to 0.
This patch might well be reverted in the future when streams support is
fully enabled and we finalized the userspace API support for this feature.

The debian tarball will be compressed into *.debian.tar.xz by default.
If you like to use a different compression mode, you can pass the

The orig tarball only supports gzip for now. The combination of

If we get woken spuriously when polling and fail the operation with
-EAGAIN again, then we generally only allow polling again if data
had been transferred at some point. This is indicated with
REQ_F_PARTIAL_IO. However, if the spurious poll triggers when the socket
was originally empty, then we haven't transferred data yet and we will
fail the poll re-arm. This either punts the socket to io-wq if it's
blocking, or it fails the request with -EAGAIN if not. Neither condition
is desirable, as the former will slow things down, while the latter
will make the application confused.
We want to ensure that a repeated poll trigger doesn't lead to infinite
work making no progress, that's what the REQ_F_PARTIAL_IO check was
for. But it doesn't protect against a loop post the first receive, and
it's unnecessarily strict if we started out with an empty socket.
Add a somewhat random retry count, just to put an upper limit on the
potential number of retries that will be done. This should be high enough
that we won't really hit it in practice, unless something needs to be
aborted anyway.

case with the CLK_OPS_PARENT_ENABLE flag combined with clk_core_is_enabled()
where it hangs the system. We'll simply assume the clk is disabled if the
parent is disabled and the flag is set. Trying to turn on the parent to check
the enable state of the clk runs into system hangs at boot. We let this bake in
-next for a couple weeks to make sure there aren't any more issues because the
last attempt to fix this ran into hangs and had to be reverted.
Note: There were some more patches to the core framework around sync_state and
disabling unused clks, but I asked for that to be reverted from the qcom PR
because it isn't ready and we're still discussing the best solution on the
list.
Outside of the core clk framework, we have the usual collection of clk driver
updates and support for new SoCs (which seems to never stop). The dirstat is
dominated by Qualcomm because they added support for quite a few SoCs this time
around and also migrated quite a few of their drivers to clk_parent_data. The
other big diff is in the Mediatek clk drivers that saw a significant rework
this cycle to similarly modernize the code, and we'll see that work continue in
the next cycle as well. Nothing really jumps out as scary here, except that the
significant churn in parent data descriptions can have typos that go unnoticed.

- Honor CLK_OPS_PARENT_ENABLE in clk_core_is_enabled()
New Drivers:
- Add a new clk-gpr-mux clock type and use it on i.MX6Q to add ENET ref

- SA8775P global clock controller
- SM8550 TCSR and display clock controller
- SM6350 clock controller
- MSM8996 CBF and APCS clock controllers

- Keep the uart clocks on i.MX93 for when earlycon is used
- Fix SPDX comment in i.MX6SLL clocks bindings header
- Drop some unnecessary spaces from i.MX8ULP clocks bindings header

On many Qualcomm platforms the PMIC RTC control and time registers are
read-only so that the RTC time can not be updated. Instead an offset
needs be stored in some machine-specific non-volatile memory, which the
driver can take into account.
Add support for storing a 32-bit offset from the Epoch in an nvmem cell
so that the RTC time can be set on such platforms.

I3C device PID could be defined in device tree and stored in
i3c_dev_boardinfo. It should be passed to i3c_device_info when
allocating a i3c_dev_desc.
Rational behind this change is: when users decide to use SETDASA to
assign a dynamic address with exactly the original static address, in
step of i3c_master_reattach_i3c_dev, this address is checked to be
taken. Then device information retrieving step is skipped. As a result,
though the i3c device is registered correctly, its device driver could
not be probed.
Tested: Tested with a I3C device. If assigned-address is set to be the
device's static address, without this change, its device driver could
not probed. And with this change, its driver is probed successfully.

When we are renaming a directory to a different directory, we need to
update '..' entry in the moved directory. However nothing prevents moved
directory from being modified and even converted from the inline format
to the normal format. When such race happens the rename code gets
confused and we crash. Fix the problem by locking the moved directory.

Now, 's_err_report' timer is init after ext4_group_desc_init() when fill
super. Theoretically, ext4_group_desc_init() may access to error handle
as follows:
__ext4_fill_super
ext4_group_desc_init
ext4_check_descriptors
ext4_get_group_desc
ext4_error
ext4_handle_error
ext4_commit_super
ext4_update_super
if (!es->s_error_count)
mod_timer(&sbi->s_err_report, jiffies + 24*60*60*HZ);
--> Accessing Uninitialized Variables
timer_setup(&sbi->s_err_report, print_daily_error_info, 0);
Maybe above issue is just theoretical, as ext4_check_descriptors() didn't
judge 'gpd' which get from ext4_get_group_desc(), if access to error handle
ext4_get_group_desc() will return NULL, then will trigger null-ptr-deref in
ext4_check_descriptors().
However, from the perspective of pure code, it is better to initialize
resource that may need to be used first.

- Provide a virtual cache topology to the guest to avoid
inconsistencies with migration on heterogenous systems. Non secure
software has no practical need to traverse the caches by set/way in
the first place.
- Add support for taking stage-2 access faults in parallel. This was an
accidental omission in the original parallel faults implementation,
but should provide a marginal improvement to machines w/o FEAT_HAFDBS
(such as hardware from the fruit company).
- A preamble to adding support for nested virtualization to KVM,
including vEL2 register state, rudimentary nested exception handling
and masking unsupported features for nested guests.
- Fixes to the PSCI relay that avoid an unexpected host SVE trap when
resuming a CPU when running pKVM.
- VGIC maintenance interrupt support for the AIC
- Improvements to the arch timer emulation, primarily aimed at reducing
the trap overhead of running nested.
- Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
interest of CI systems.
- Avoid VM-wide stop-the-world operations when a vCPU accesses its own
redistributor.
- Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions
in the host.
- Aesthetic and comment/kerneldoc fixes
- Drop the vestiges of the old Columbia mailing list and add [Oliver]
as co-maintainer
This also drags in arm64's 'for-next/sme2' branch, because both it and
the PSCI relay changes touch the EL2 initialization code.
RISC-V:
- Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE
- Correctly place the guest in S-mode after redirecting a trap to the guest
- Redirect illegal instruction traps to guest
- SBI PMU support for guest
s390:
- Two patches sorting out confusion between virtual and physical
addresses, which currently are the same on s390.
- A new ioctl that performs cmpxchg on guest memory
- A few fixes
x86:
- Change tdp_mmu to a read-only parameter
- Separate TDP and shadow MMU page fault paths
- Enable Hyper-V invariant TSC control
- Fix a variety of APICv and AVIC bugs, some of them real-world,
some of them affecting architecurally legal but unlikely to
happen in practice
- Mark APIC timer as expired if its in one-shot mode and the count
underflows while the vCPU task was being migrated
- Advertise support for Intel's new fast REP string features
- Fix a double-shootdown issue in the emergency reboot code
- Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give SVM
similar treatment to VMX
- Update Xen's TSC info CPUID sub-leaves as appropriate
- Add support for Hyper-V's extended hypercalls, where "support" at this
point is just forwarding the hypercalls to userspace
- Clean up the kvm->lock vs. kvm->srcu sequences when updating the PMU and
MSR filters
- One-off fixes and cleanups
- Fix and cleanup the range-based TLB flushing code, used when KVM is
running on Hyper-V
- Add support for filtering PMU events using a mask. If userspace
wants to restrict heavily what events the guest can use, it can now
do so without needing an absurd number of filter entries
- Clean up KVM's handling of "PMU MSRs to save", especially when vPMU
support is disabled
- Add PEBS support for Intel Sapphire Rapids
- Fix a mostly benign overflow bug in SEV's send|receive_update_data()
- Move several SVM-specific flags into vcpu_svm
x86 Intel:
- Handle NMI VM-Exits before leaving the noinstr region
- A few trivial cleanups in the VM-Enter flows
- Stop enabling VMFUNC for L1 purely to document that KVM doesn't support
EPTP switching (or any other VM function) for L1
- Fix a crash when using eVMCS's enlighted MSR bitmaps
Generic:
- Clean up the hardware enable and initialization flow, which was
scattered around multiple arch-specific hooks. Instead, just
let the arch code call into generic code. Both x86 and ARM should
benefit from not having to fight common KVM code's notion of how
to do initialization.
- Account allocations in generic kvm_arch_alloc_vm()
- Fix a memory leak if coalesced MMIO unregistration fails
selftests:
- On x86, cache the CPU vendor (AMD vs. Intel) and use the info to emit
the correct hypercall instruction instead of relying on KVM to patch
in VMMCALL
- Use TAP interface for kvm_binary_stats_test and tsc_msrs_test

Pull kvm updates from Paolo Bonzini:
"ARM:
- Provide a virtual cache topology to the guest to avoid
inconsistencies with migration on heterogenous systems. Non secure
software has no practical need to traverse the caches by set/way in
the first place
- Add support for taking stage-2 access faults in parallel. This was
an accidental omission in the original parallel faults
implementation, but should provide a marginal improvement to
machines w/o FEAT_HAFDBS (such as hardware from the fruit company)
- A preamble to adding support for nested virtualization to KVM,
including vEL2 register state, rudimentary nested exception
handling and masking unsupported features for nested guests
- Fixes to the PSCI relay that avoid an unexpected host SVE trap when
resuming a CPU when running pKVM
- VGIC maintenance interrupt support for the AIC
- Improvements to the arch timer emulation, primarily aimed at
reducing the trap overhead of running nested
- Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
interest of CI systems
- Avoid VM-wide stop-the-world operations when a vCPU accesses its
own redistributor
- Serialize when toggling CPACR_EL1.SMEN to avoid unexpected
exceptions in the host
- Aesthetic and comment/kerneldoc fixes
- Drop the vestiges of the old Columbia mailing list and add [Oliver]
as co-maintainer
RISC-V:
- Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE
- Correctly place the guest in S-mode after redirecting a trap to the
guest
- Redirect illegal instruction traps to guest
- SBI PMU support for guest
s390:
- Sort out confusion between virtual and physical addresses, which
currently are the same on s390
- A new ioctl that performs cmpxchg on guest memory
- A few fixes
x86:
- Change tdp_mmu to a read-only parameter
- Separate TDP and shadow MMU page fault paths
- Enable Hyper-V invariant TSC control
- Fix a variety of APICv and AVIC bugs, some of them real-world, some
of them affecting architecurally legal but unlikely to happen in
practice
- Mark APIC timer as expired if its in one-shot mode and the count
underflows while the vCPU task was being migrated
- Advertise support for Intel's new fast REP string features
- Fix a double-shootdown issue in the emergency reboot code
- Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give
