commit 39d26a8f2efcb8b5665fe7d54a7dba306a8f1dff upstream.
mlx5 Rx flow steering and CQE handling enable the driver to be able to
update an skb's md_dst attribute as MACsec when MACsec traffic arrives when
a device is configured for offloading. Advertise this to the core stack to
take advantage of this capability.

update md_dst
commit 642c984dd0e37dbaec9f87bd1211e5fac1f142bf upstream.
Can now correctly identify where the packets should be delivered by using
md_dst or its absence on devices that provide it.
This detection is not possible without device drivers that update md_dst. A
fallback pattern should be used for supporting such device drivers. This
fallback mode causes multicast messages to be cloned to both the non-macsec
and macsec ports, independent of whether the multicast message received was
encrypted over MACsec or not. Other non-macsec traffic may also fail to be
handled correctly for devices in promiscuous mode.

during offloads
commit 475747a19316b08e856c666a20503e73d7ed67ed upstream.
Omit rx_use_md_dst comment in upstream commit since macsec_ops is not
documented.
Cannot know whether a Rx skb missing md_dst is intended for MACsec or not
without knowing whether the device is able to update this field during an
offload. Assume that an offload to a MACsec device cannot support updating
md_dst by default. Capable devices can advertise that they do indicate that
an skb is related to a MACsec offloaded packet using the md_dst.

[ Upstream commit bf6e4ee5c43690e4c5a8a057bbcd4ff986bed052 ]
The power_supply frame-work is not really designed for there to be
long living in kernel references to power_supply devices.
Specifically unregistering a power_supply while some other code has
a reference to it triggers a WARN in power_supply_unregister():
WARN_ON(atomic_dec_return(&psy->use_cnt));
Folllowed by the power_supply still getting removed and the
backing data freed anyway, leaving the tusb1210 charger-detect code
with a dangling reference, resulting in a crash the next time
tusb1210_get_online() is called.
Fix this by only holding the reference in tusb1210_get_online()
freeing it at the end of the function. Note this still leaves
a theoretical race window, but it avoids the issue when manually
rmmod-ing the charger chip driver during development.

[ Upstream commit 55491a5fa163bf15158f34f3650b3985f25622b9 ]
Currently the PCIe v3 PHY driver only sets the pcie1ln_sel bits, but
does not clear them because of an incorrect write mask. This fixes up
the issue by using a newly introduced constant for the write mask.
While at it also introduces a proper GENMASK based constant for the
PCIE30_PHY_MODE.

[ Upstream commit f8020dfb311d2b6cf657668792aaa5fa8863a7dd ]
So far all RK3588 boards use fully aggregated PCIe. CM3588 is one
of the few boards using this feature and apparently it is broken.
The PHY offers the following mapping options:
port 0 lane 0 - always mapped to controller 0 (4L)
port 0 lane 1 - to controller 0 or 2 (1L0)
port 1 lane 0 - to controller 0 or 1 (2L)
port 1 lane 1 - to controller 0, 1 or 3 (1L1)
The data-lanes DT property maps these as follows:
0 = no controller (unsupported by the HW)
1 = 4L
2 = 2L
3 = 1L0
4 = 1L1
That allows the following configurations with first column being the
mainline data-lane mapping, second column being the downstream name,
third column being PCIE3PHY_GRF_CMN_CON0 and PHP_GRF_PCIESEL register
values and final column being the user visible lane setup:
<1 1 1 1> = AGGREG = [4 0] = x4 (aggregation)
<1 1 2 2> = NANBNB = [0 0] = x2 x2 (no bif.)
<1 3 2 2> = NANBBI = [1 1] = x2 x1x1 (bif. of port 0)
<1 1 2 4> = NABINB = [2 2] = x1x1 x2 (bif. of port 1)
<1 3 2 4> = NABIBI = [3 3] = x1x1 x1x1 (bif. of both ports)
The driver currently does not program PHP_GRF_PCIESEL correctly, which
is fixed by this patch. As a side-effect the new logic is much simpler
than the old logic.

The existing residual calculation returns an incorrect value when
bytes_xfer == bytes_req. This scenario occurs particularly with drivers
like UART where DMA is scheduled for maximum number of bytes and is
terminated when the bytes inflow stops. At higher baud rates, it could
request the tx_status while there is no bytes left to transfer. This will
lead to incorrect residual being set. Hence return residual as '0' when
bytes transferred equals to the bytes requested.

commit a0a8d15a798be4b8f20aca2ba91bf6b688c6a640 upstream.
The TDX guest platform takes one bit from the physical address to
indicate if the page is shared (accessible by VMM). This bit is not part
of the physical_mask and is not preserved during mprotect(). As a
result, the 'shared' bit is lost during mprotect() on shared mappings.
_COMMON_PAGE_CHG_MASK specifies which PTE bits need to be preserved
during modification. AMD includes 'sme_me_mask' in the define to
preserve the 'encrypt' bit.
To cover both Intel and AMD cases, include 'cc_mask' in
_COMMON_PAGE_CHG_MASK instead of 'sme_me_mask'.

commit 21c9fb611c25d5cd038f6fe485232e7884bb0b3d upstream.
I ran into a randconfig build failure with UBSAN using gcc-13.2:
arm-linux-gnueabi-ld: error: unplaced orphan section `.bss..Lubsan_data31' from `drivers/mtd/nand/raw/diskonchip.o'
I'm not entirely sure what is going on here, but I suspect this has something
to do with the check for the end of the doc_locations[] array that contains
an (unsigned long)0xffffffff element, which is compared against the signed
(int)0xffffffff. If this is the case, we should get a runtime check for
undefined behavior, but we instead get an unexpected build-time error.
I would have expected this to work fine on 32-bit architectures despite the
signed integer overflow, though on 64-bit architectures this likely won't
ever work.
Changing the contition to instead check for the size of the array makes the
code safe everywhere and avoids the ubsan check that leads to the link
error. The loop code goes back to before 2.6.12.

commit 78d9161d2bcd442d93d917339297ffa057dbee8c upstream.
With deferred IO enabled, a page fault happens when data is written to the
framebuffer device. Then driver determines which page is being updated by
calculating the offset of the written virtual address within the virtual
memory area, and uses this offset to get the updated page within the
internal buffer. This page is later copied to hardware (thus the name
"deferred IO").
This offset calculation is only correct if the virtual memory area is
mapped to the beginning of the internal buffer. Otherwise this is wrong.
For example, if users do:
mmap(ptr, 4096, PROT_WRITE, MAP_FIXED | MAP_SHARED, fd, 0xff000);
Then the virtual memory area will mapped at offset 0xff000 within the
internal buffer. This offset 0xff000 is not accounted for, and wrong page
is updated.
Correct the calculation by using vmf->pgoff instead. With this change, the
variable "offset" will no longer hold the exact offset value, but it is
rounded down to multiples of PAGE_SIZE. But this is still correct, because
this variable is only used to calculate the page offset.

b44_free_rings() accesses b44::rx_buffers (and ::tx_buffers)
unconditionally, but b44::rx_buffers is only valid when the
device is up (they get allocated in b44_open(), and deallocated
again in b44_close()), any other time these are just a NULL pointers.
So if you try to change the pause params while the network interface
is disabled/administratively down, everything explodes (which likely
netifd tries to do).

commit f489c948028b69cea235d9c0de1cc10eeb26a172 upstream.
commit 2f4a4d63a193 ("ACPI: CPPC: Use access_width over bit_width for system
memory accesses") modified cpc_read()/cpc_write() to use access_width to
read CPC registers.
However, for PCC registers the access width field in the ACPI register
macro specifies the PCC subspace ID. For non-zero PCC subspace ID it is
incorrectly treated as access width. This causes errors when reading
from PCC registers in the CPPC driver.
For PCC registers, base the size of read/write on the bit width field.
The debug message in cpc_read()/cpc_write() is updated to print relevant
information for the address space type used to read the register.

commit 2f4a4d63a193be6fd530d180bb13c3592052904c upstream.
To align with ACPI 6.3+, since bit_width can be any 8-bit value, it
cannot be depended on to be always on a clean 8b boundary. This was
uncovered on the Cobalt 100 platform.

Instead, use access_width to determine the size and use the offset and
width to shift and mask the bits to read/write out. Make sure to add a
check for system memory since pcc redefines the access_width to
subspace id.
If access_width is not set, then fall back to using bit_width.

commit c26591afd33adce296c022e3480dea4282b7ef91 upstream.
The error handling path in its_vpe_irq_domain_alloc() causes a double free
when its_vpe_init() fails after successfully allocating at least one
interrupt. This happens because its_vpe_irq_domain_free() frees the
interrupts along with the area bitmap and the vprop_page and
its_vpe_irq_domain_alloc() subsequently frees the area bitmap and the
vprop_page again.
Fix this by unconditionally invoking its_vpe_irq_domain_free() which
handles all cases correctly and by removing the bitmap/vprop_page freeing
from its_vpe_irq_domain_alloc().

commit efb44ff64c95340b06331fc48634b99efc9dd77c upstream.
As with most architectures, allow handling of read faults in VMAs that
have VM_WRITE but without VM_READ (WRITE implies READ).
Otherwise, reading before writing a write-only memory will error while
reading after writing everything is fine.
BTW, move the VM_EXEC judgement before VM_READ/VM_WRITE to make logic a
little clearer.

commit fe42754b94a42d08cf9501790afc25c4f6a5f631 upstream.
Rename x86's to CPU_MITIGATIONS, define it in generic code, and force it
on for all architectures exception x86. A recent commit to turn
mitigations off by default if SPECULATION_MITIGATIONS=n kinda sorta
missed that "cpu_mitigations" is completely generic, whereas
SPECULATION_MITIGATIONS is x86-specific.
Rename x86's SPECULATIVE_MITIGATIONS instead of keeping both and have it
select CPU_MITIGATIONS, as having two configs for the same thing is
unnecessary and confusing. This will also allow x86 to use the knob to
manage mitigations that aren't strictly related to speculative
execution.
Use another Kconfig to communicate to common code that CPU_MITIGATIONS
is already defined instead of having x86's menu depend on the common
CPU_MITIGATIONS. This allows keeping a single point of contact for all
of x86's mitigations, and it's not clear that other architectures *want*
to allow disabling mitigations at compile-time.

Fix this by using kvzalloc() which zeroes out the memory on allocation.

commit 9c0f59e47a90c54d0153f8ddc0f80d7a36207d0e upstream.
The flag I2C_HID_READ_PENDING is used to serialize I2C operations.
However, this is not necessary, because I2C core already has its own
locking for that.
More importantly, this flag can cause a lock-up: if the flag is set in
i2c_hid_xfer() and an interrupt happens, the interrupt handler
(i2c_hid_irq) will check this flag and return immediately without doing
anything, then the interrupt handler will be invoked again in an
infinite loop.
Since interrupt handler is an RT task, it takes over the CPU and the
flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag.

commit f8def10f73a516b771051a2f70f2f0446902cb4f upstream.
Generic sdhci code registers LED device and uses host->runtime_suspended
flag to protect access to it. The sdhci-msm driver doesn't set this flag,
which causes a crash when LED is accessed while controller is runtime
suspended. Fix this by setting the flag correctly.

commit 73e87c0a49fda31d7b589edccf4c72e924411371 upstream.
Qualcomm ROME controllers can be registered from the Bluetooth line
discipline and in this case the HCI UART serdev pointer is NULL.
Add the missing sanity check to prevent a NULL-pointer dereference when
wakeup() is called for a non-serdev controller during suspend.
Just return true for now to restore the original behaviour and address
the crash with pre-6.2 kernels, which do not have commit e9b3e5b8c657
("Bluetooth: hci_qca: only assign wakeup with serial port support") that
causes the crash to happen already at setup() time.

commit d1a5a7eede2977da3d2002d5ea3b519019cc1a98 upstream.
Add the support ID(0x0bda, 0x4853) to usb_device_id table for
Realtek RTL8852BE.
Without this change the device utilizes an obsolete version of
the firmware that is encoded in it rather than the updated Realtek
firmware and config files from the firmware directory. The latter
files implement many new features.
The device table is as follows:
