[ Upstream commit 9aa5757e1f ]
FID is directly mapped to VID. However, configuring a MAC address with a
VID != 0 resulted in incorrect configuration due to an incorrect bit
mask. This kernel commit fixed the issue by correcting the bit mask and
ensuring proper configuration of MAC addresses with non-zero VID.

[ Upstream commit 392ff7a84c ]
Current regmap bulk access is broken, resulting to wrong reads/writes
if ksz_read64/ksz_write64 functions are used.
Mostly this issue was visible by using ksz8_fdb_dump(), which returned
corrupt MAC address.
The reason is that regmap was configured to have max_raw_read/write,
even if ksz8863_mdio_read/write functions are able to handle unlimited
read/write accesses. On ksz_read64 function we are using multiple 32bit
accesses by incrementing each access by 1 instead of 4. Resulting buffer
had 01234567.12345678 instead of 01234567.89abcdef.
We have multiple ways to fix it:
- enable 4 byte alignment for 32bit accesses. Since the HW do not have
this requirement. It will break driver.
- disable max_raw_* limit.
This patch is removing max_raw_* limit for regmap accesses in ksz8863_smi.

The probe function sets priv->chip_data to (void *)priv + sizeof(*priv)
with the expectation that priv has enough trailing space.
However, only realtek-smi actually allocated this chip_data space.
Do likewise in realtek-mdio to fix out-of-bounds accesses.
These accesses likely went unnoticed so far, because of an (unused)
buf[4096] member in struct realtek_priv, which caused kmalloc to
round up the allocated buffer to a big enough size, so nothing of
value was overwritten. With a different allocator (like in the barebox
bootloader port of the driver) or with KASAN, the memory corruption
becomes quickly apparent.

At NIC reset, some offload features related to encapsulated traffic
might have changed (this mainly happens if the firmware-variant is
changed with the sfboot userspace tool). Because of this, features are
checked and set again at reset time.
However, this was not done right, and some features were improperly
overwritten at NIC reset:
- Tunneled IPv6 segmentation was always disabled
- Features disabled with ethtool were reenabled
- Features that becomes unsupported after the reset were not disabled
Also, checking if the device supports IPV6_CSUM to enable TSO6 is no
longer necessary because all currently supported devices support it.
Additionally, move the assignment of some other features to the
EF10_OFFLOAD_FEATURES macro, like it is done in ef100, leaving the

[ Upstream commit 943d045a6d ]
NFS server Duplicate Request Cache (DRC) algorithms rely on NFS clients
reconnecting using the same local TCP port. Unique NFS operations are
identified by the per-TCP connection set of XIDs. This prevents file
corruption when non-idempotent NFS operations are retried.
Currently, NFS client TCP connections are using different local TCP ports
when reconnecting to NFS servers.
After an NFS server initiates shutdown of the TCP connection, the NFS
client's TCP socket is set to NULL after the socket state has reached
TCP_LAST_ACK(9). When reconnecting, the new socket attempts to reuse
the same local port but fails with EADDRNOTAVAIL (99). This forces the
socket to use a different local TCP port to reconnect to the remote NFS
server.

The recent support of low latency playback in USB-audio driver made
the snd_usb_queue_pending_output_urbs() function to be called via PCM
ack ops. In the new code path, the function is performed already in
the PCM stream lock. The problem is that, when an XRUN is detected,
the function calls snd_pcm_xrun() to notify, but snd_pcm_xrun() is
supposed to be called only outside the stream lock. As a result, it
leads to a deadlock of PCM stream locking.
For avoiding such a recursive locking, this patch adds an additional
check to the code paths in PCM core that call the ack callback; now it
checks the error code from the callback, and if it's -EPIPE, the XRUN
is handled in the PCM core side gracefully. Along with it, the
USB-audio driver code is changed to follow that, i.e. -EPIPE is
returned instead of the explicit snd_pcm_xrun() call when the function
is performed already in the stream lock.

In case when VCPU is blocked due to WFI, we schedule the timer
from `kvm_riscv_vcpu_timer_blocking()` to keep timer interrupt
ticking.
But in case when delta_ns comes to be zero, we never schedule
the timer and VCPU keeps sleeping indefinitely until any activity
is done with VM console.
This is easily reproduce-able using kvmtool.
./lkvm-static run -c1 --console virtio -p "earlycon root=/dev/vda" \
-k ./Image -d rootfs.ext4
Also, just add a print in kvm_riscv_vcpu_vstimer_expired() to
check the interrupt delivery and run `top` or similar auto-upating
cmd from guest. Within sometime one can notice that print from
timer expiry routine stops and the `top` cmd output will stop
updating.
This change fixes this by making sure we schedule the timer even
with delta_ns being zero to bring the VCPU out of sleep immediately.

[ Upstream commit 75dce6a941 ]
wait_for_completion_timeout() and readl_poll_timeout() don't handle their
return value the same way.
wait_for_completion_timeout() returns 0 on time out (and >0 in all other
cases)
readl_poll_timeout() returns 0 on success and -ETIMEDOUT upon a timeout.
In order for the error handling path to work in both cases, the logic
against wait_for_completion_timeout() needs to be inverted.

[ Upstream commit 4ce341de6c ]
This structure must be zeroed, because it's field 'hw->core' is used as
'parent' in 'clk_core_fill_parent_index()', but it will be uninitialized.
This happens, because when this struct is not zeroed, pointer 'hw' is
"initialized" by garbage, which is valid pointer, but points to some
garbage. So 'hw' will be dereferenced, but 'core' contains some random
data which will be interpreted as a pointer. The following backtrace is
result of dereference of such pointer:

XSK redirecting XDP programs require linearity, hence applies
restrictions on the MTU. For PAGE_SIZE=4K, MTU shouldn't exceed 3498.
Features that contradict with XDP such HW-LRO and HW-GRO are enforced
by the driver in advance, during XSK params validation, except for MTU,
which was not enforced before this patch.
This has been spotted during test scenario described below:
Attaching xdpsock program (PAGE_SIZE=4K), with MTU < 3498, detaching
XDP program, changing the MTU to arbitrary value in the range
[3499, 3754], attaching XDP program again, which ended up with failure
since MTU is > 3498.
This commit lowers the XSK MTU limitation to be aligned with XDP MTU
limitation, since XSK socket is meaningless without XDP program.

[ Upstream commit 6015b1aca1 ]
The getaffinity() system call uses 'cpumask_size()' to decide how big
the CPU mask is - so far so good. It is indeed the allocation size of a
cpumask.
But the code also assumes that the whole allocation is initialized
without actually doing so itself. That's wrong, because we might have
fixed-size allocations (making copying and clearing more efficient), but
not all of it is then necessarily used if 'nr_cpu_ids' is smaller.
Having checked other users of 'cpumask_size()', they all seem to be ok,
either using it purely for the allocation size, or explicitly zeroing
the cpumask before using the size in bytes to copy it.
See for example the ublk_ctrl_get_queue_affinity() function that uses
the proper 'zalloc_cpumask_var()' to make sure that the whole mask is
cleared, whether the storage is on the stack or if it was an external
allocation.
Fix this by just zeroing the allocation before using it. Do the same
for the compat version of sched_getaffinity(), which had the same logic.
Also, for consistency, make sched_getaffinity() use 'cpumask_bits()' to
access the bits. For a cpumask_var_t, it ends up being a pointer to the
same data either way, but it's just a good idea to treat it like you
would a 'cpumask_t'. The compat case already did that.

Recent firmware changes modified the curve duration from 32 to 64 bits,
which breaks volume ramps. A simple solution would be to change the
definition, but unfortunately the ASoC topology framework only supports
up to 32 bit tokens.
This patch suggests breaking the 64 bit value in low and high parts, with
only the low-part extracted from topology and high-part only zeroes. Since
the curve duration is represented in hundred of nanoseconds, we can still
represent a 400s ramp, which is just fine. The defacto ABI change has no
effect on existing users since the IPC4 firmware has not been released just
yet.

The logic for the ioremap is to find the resource index 3 (IRAM) and
infer the BAR address by subtracting the IRAM offset. The BAR size
defined in hardware specifications is 2MB.
The commit 5947b2726b ("ASoC: SOF: Intel: Check the bar size before
remapping") tried to find the BAR size by querying the resource length
instead of a pre-canned value, but by requesting the size for index 3
it only gets the size of the IRAM. That's obviously wrong and prevents
the probe from proceeding.
This commit attempted to fix an issue in a fuzzing/simulated
environment but created another on actual devices, so the best course
of action is to revert that change.
