V3: drop changes where readbacks have implemented. This patch set
is to add readbacks only.
V2: use common register UVD_STATUS for readback (standard PCI MMIO
behavior, i.e. readback post all writes to let the writes hit
the hardware)
add readback in ..._stop() for more coverage.
Similar to the changes made for VCN v4.0.5 where readback to post the
writes to avoid race with the doorbell, the addition of register
readback support in other VCN versions is intended to prevent potential
race conditions, even though such issues have not been observed yet.
This change ensures consistency across different VCN variants and helps
avoid similar issues. The overhead introduced is negligible.

When running these commands on DUT (and similar at the other end)
ip link set dev eth0 up
ip link add link eth0 name eth0.10 type vlan id 10
ip addr add 10.0.0.1/24 dev eth0.10
ip link set dev eth0.10 up
ping 10.0.0.2
The ping will fail.
The reason why is failing is because, the network interfaces for lan966x
have a flag saying that the HW can insert the vlan tags into the
frames(NETIF_F_HW_VLAN_CTAG_TX). Meaning that the frames that are
transmitted don't have the vlan tag inside the skb data, but they have
it inside the skb. We already get that vlan tag and put it in the IFH
but the problem is that we don't configure the HW to rewrite the frame
when the interface is in host mode.
The fix consists in actually configuring the HW to insert the vlan tag
if it is different than 0.

commit 083466754596 ("cpufreq: ACPI: Fix max-frequency computation")
modified get_max_boost_ratio() to return the nominal_freq advertised
in the _CPC object. This was for the purposes of computing the maximum
frequency. The frequencies advertised in _CPC objects are in
MHz. However, cpufreq expects the frequency to be in KHz. Since the
nominal_freq returned by get_max_boost_ratio() was not in KHz but
instead in MHz,the cpuinfo_max_frequency that was computed using this
nominal_freq was incorrect and an invalid value which resulted in
cpufreq reporting the P0 frequency as the cpuinfo_max_freq.
Fix this by converting the nominal_freq to KHz before returning the
same from get_max_boost_ratio().

The "freq" variable is in terms of MHz and "max_val_cycles" is in terms
of Hz. The fact that "max_val_cycles" is a u64 suggests that support
for high frequency is intended but the "freq_khz * 1000" would overflow
the u32 type if we went above 4GHz. Use unsigned long long type for the
mutliplication to prevent that.

executing linkwatch_work().
To resolve this issue, call netif_device_detach() during the Ethernet

kernel and prevent the suspend/resume hang.

bus_id is currently derived from the ethernetX alias. If one is missing
for the device, 0 is used. If ethernet0 points to another stmmac device
or if there are 2+ stmmac devices without an ethernet alias, then bus_id
will be 0 for all of those.
This is an issue because the bus_id is used to generate the mdio bus id
(new_bus->id in drivers/net/ethernet/stmicro/stmmac/stmmac_mdio.c
stmmac_mdio_register) and this needs to be unique.
This allows to avoid needing to define ethernet aliases for devices with
multiple stmmac controllers (such as the Rockchip RK3588) for multiple
stmmac devices to probe properly.
Obviously, the bus_id isn't guaranteed to be stable across reboots if no
alias is set for the device but that is easily fixed by simply adding an
alias if this is desired.

echo_skb_max should define the supported upper limit of echo_skb[]
allocated inside the netdevice's priv. The corresponding size value
provided by this driver to alloc_candev() is KVASER_PCIEFD_CAN_TX_MAX_COUNT
which is 17.
But later echo_skb_max is rounded up to the nearest power of two (for the
max case, that would be 32) and the tx/ack indices calculated further
during tx/rx may exceed the upper array boundary. Kasan reported this for
the ack case inside kvaser_pciefd_handle_ack_packet(), though the xmit
function has actually caught the same thing earlier.

Tx max count definitely matters for kvaser_pciefd_tx_avail(), but for seq
numbers' generation that's not the case - we're free to calculate them as
would be more convenient, not taking tx max count into account. The only
downside is that the size of echo_skb[] should correspond to the max seq
number (not tx max count), so in some situations a bit more memory would
be consumed than could be.
Thus make the size of the underlying echo_skb[] sufficient for the rounded
max tx value.

In mii_nway_restart() the code attempts to call
mii->mdio_read which is ch9200_mdio_read(). ch9200_mdio_read()
utilises a local buffer called "buff", which is initialised
with control_read(). However "buff" is conditionally
initialised inside control_read():
if (err == size) {
memcpy(data, buf, size);
}
If the condition of "err == size" is not met, then
"buff" remains uninitialised. Once this happens the
uninitialised "buff" is accessed and returned during
ch9200_mdio_read():
return (buff[0] | buff[1] << 8);
The problem stems from the fact that ch9200_mdio_read()
ignores the return value of control_read(), leading to
uinit-access of "buff".
To fix this we should check the return value of
control_read() and return early on error.

Pull networking updates from Paolo Abeni:
"Core:
- Implement the Device Memory TCP transmit path, allowing zero-copy
data transmission on top of TCP from e.g. GPU memory to the wire.
- Move all the IPv6 routing tables management outside the RTNL scope,
under its own lock and RCU. The route control path is now 3x times
faster.
- Convert queue related netlink ops to instance lock, reducing again
the scope of the RTNL lock. This improves the control plane
scalability.
- Refactor the software crc32c implementation, removing unneeded
abstraction layers and improving significantly the related
micro-benchmarks.
- Optimize the GRO engine for UDP-tunneled traffic, for a 10%
performance improvement in related stream tests.
- Cover more per-CPU storage with local nested BH locking; this is a
prep work to remove the current per-CPU lock in local_bh_disable()
on PREMPT_RT.
- Introduce and use nlmsg_payload helper, combining buffer bounds
verification with accessing payload carried by netlink messages.
Netfilter:
- Rewrite the procfs conntrack table implementation, improving
considerably the dump performance. A lot of user-space tools still
use this interface.
- Implement support for wildcard netdevice in netdev basechain and
flowtables.
- Integrate conntrack information into nft trace infrastructure.
- Export set count and backend name to userspace, for better
introspection.
BPF:
- BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops
programs and can be controlled in similar way to traditional qdiscs
using the "tc qdisc" command.
- Refactor the UDP socket iterator, addressing long standing issues
WRT duplicate hits or missed sockets.
Protocols:
- Improve TCP receive buffer auto-tuning and increase the default
upper bound for the receive buffer; overall this improves the
single flow maximum thoughput on 200Gbs link by over 60%.
- Add AFS GSSAPI security class to AF_RXRPC; it provides transport
security for connections to the AFS fileserver and VL server.
- Improve TCP multipath routing, so that the sources address always
matches the nexthop device.
- Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS,
and thus preventing DoS caused by passing around problematic FDs.
- Retire DCCP socket. DCCP only receives updates for bugs, and major
distros disable it by default. Its removal allows for better
organisation of TCP fields to reduce the number of cache lines hit
in the fast path.
- Extend TCP drop-reason support to cover PAWS checks.
Driver API:
- Reorganize PTP ioctl flag support to require an explicit opt-in for
the drivers, avoiding the problem of drivers not rejecting new
unsupported flags.
- Converted several device drivers to timestamping APIs.
- Introduce per-PHY ethtool dump helpers, improving the support for
dump operations targeting PHYs.
Tests and tooling:
- Add support for classic netlink in user space C codegen, so that
ynl-c can now read, create and modify links, routes addresses and
qdisc layer configuration.
- Add ynl sub-types for binary attributes, allowing ynl-c to output
known struct instead of raw binary data, clarifying the classic
netlink output.
- Extend MPTCP selftests to improve the code-coverage.
- Add tests for XDP tail adjustment in AF_XDP.
New hardware / drivers:
- OpenVPN virtual driver: offload OpenVPN data channels processing to
the kernel-space, increasing the data transfer throughput WRT the
user-space implementation.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"The headline feature is the re-enablement of support for Arm's
Scalable Matrix Extension (SME) thanks to a bumper crop of fixes
from Mark Rutland.
If matrices aren't your thing, then Ryan's page-table optimisation
work is much more interesting.
Summary:
ACPI, EFI and PSCI:
- Decouple Arm's "Software Delegated Exception Interface" (SDEI)
support from the ACPI GHES code so that it can be used by platforms
booted with device-tree
- Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
runtime calls
- Fix a node refcount imbalance in the PSCI device-tree code
CPU Features:
- Ensure register sanitisation is applied to fields in ID_AA64MMFR4
- Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM
guests can reliably query the underlying CPU types from the VMM
- Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
to our context-switching, signal handling and ptrace code
Entry code:
- Hook up TIF_NEED_RESCHED_LAZY so that CONFIG_PREEMPT_LAZY can be
selected
Memory management:
- Prevent BSS exports from being used by the early PI code
- Propagate level and stride information to the low-level TLB
invalidation routines when operating on hugetlb entries
- Use the page-table contiguous hint for vmap() mappings with
VM_ALLOW_HUGE_VMAP where possible
- Optimise vmalloc()/vmap() page-table updates to use "lazy MMU mode"
and hook this up on arm64 so that the trailing DSB (used to publish
the updates to the hardware walker) can be deferred until the end
of the mapping operation
- Extend mmap() randomisation for 52-bit virtual addresses (on par
with 48-bit addressing) and remove limited support for
randomisation of the linear map
Perf and PMUs:
- Add support for probing the CMN-S3 driver using ACPI
- Minor driver fixes to the CMN, Arm-NI and amlogic PMU drivers
Selftests:
- Fix FPSIMD and SME tests to align with the freshly re-enabled SME
support
- Fix default setting of the OUTPUT variable so that tests are
installed in the right location
vDSO:
- Replace raw counter access from inline assembly code with a call to
the the __arch_counter_get_cntvct() helper function
Miscellaneous:
- Add some missing header inclusions to the CCA headers
- Rework rendering of /proc/cpuinfo to follow the x86-approach and
avoid repeated buffer expansion (the user-visible format remains
identical)
- Remove redundant selection of CONFIG_CRC32
- Extend early error message when failing to map the device-tree
blob"

The Cadence PCIe controller driver defines message codes in enum
cdns_pcie_msg_code duplicating the existing PCIE_MSG_CODE_* definitions in
drivers/pci/pci.h. The driver only uses ASSERT_INTA and DEASSERT_INTA codes
from this enum.
Remove the redundant Cadence-specific enum definitions and use the ones
available in drivers/pci/pci.h. This helps in avoiding code duplication,
maintaining consistency with the spec, and simplifying the code
maintenance.

Also rename the parameter 'interrupts' to 'nr_irqs', in both the wrapper

When allocating the shared ctrl/SPAD space, epf_ntb_config_spad_bar_alloc()
should not try to handle the size quirks for underlying BAR, whether it is
fixed size or alignment. This is already handled by pci_epf_alloc_space().
Also, when handling the alignment, this allocates more space than
necessary. For example, with a SPAD size of 1024B and a ctrl size of 308B,
the space necessary is 1332B. If the alignment is 1MB,
epf_ntb_config_spad_bar_alloc() tries to allocate 2MB where 1MB would have
been more than enough.
Drop the handling of the BAR size quirks and let pci_epf_alloc_space()
handle that. Just make sure the 32bits SPAD register are aligned on 32bits.

When allocating space for an endpoint function on a BAR with a fixed size,
the size saved in 'struct pci_epf_bar.size' should be the fixed size as
expected by pci_epc_set_bar().
However, if pci_epf_alloc_space() increased the allocation size to
accommodate iATU alignment requirements, it previously saved the larger
aligned size in .size, which broke pci_epc_set_bar().
To solve this, keep the fixed BAR size in .size and save the aligned size
in a new .aligned_size for use when deallocating it.

Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with
devres changes also in the driver-core tree. Along with the drm core
abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.
The other big NVIDIA related one is nouveau adds support for
Hopper/Blackwell GPUs, this required a new GSP firmware update to
570.144, and a bunch of rework in order to support multiple fw
interfaces.
There is also the introduction of an asahi uapi header file as a
precursor to getting the real driver in later, but to unblock
userspace mesa packages while the driver is trapped behind rust
enablement.
Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe,
and msm being the main ones, and some changes to vsprintf.
new drivers:
- bring in the asahi uapi header standalone
- nova-drm: stub driver
rust dependencies (for nova-core):
- auxiliary
- bus abstractions
- driver registration
- sample driver
- devres changes from driver-core
- revocable changes
core:
- add Apple fourcc modifiers
- add virtio capset definitions
