[ Upstream commit ca0b44e20a6f3032224599f02e7c8fb49525c894 ]
The existing behavior of ib_umad, which maintains received MAD
packets in an unbounded list, poses a risk of uncontrolled growth.
As user-space applications extract packets from this list, the rate
of extraction may not match the rate of incoming packets, leading
to potential list overflow.
To address this, we introduce a limit to the size of the list. After
considering typical scenarios, such as OpenSM processing, which can
handle approximately 100k packets per second, and the 1-second retry
timeout for most packets, we set the list size limit to 200k. Packets
received beyond this limit are dropped, assuming they are likely timed
out by the time they are handled by user-space.
Notably, packets queued on the receive list due to reasons like
timed-out sends are preserved even when the list is full.

[ Upstream commit 309422d280748c74f57f471559980268ac27732a ]
This structure is embedded in multiple other structures that are packed,
which conflicts with it being aligned.

Mark it as being packed.
Marking the inner struct as 'packed' does not change the layout, since the
whole struct is already packed, it just silences the clang warning. See
also this llvm discussion:

[ Upstream commit a6683c690bbfd1f371510cb051e8fa49507f3f5e ]
lima uses a shared interrupt, so the interrupt handlers must be prepared
to be called at any time. At driver removal time, the clocks are
disabled early and the interrupts stay registered until the very end of
the remove process due to the devm usage.
This is potentially a bug as the interrupts access device registers
which assumes clocks are enabled. A crash can be triggered by removing
the driver in a kernel with CONFIG_DEBUG_SHIRQ enabled.
This patch frees the interrupts at each lima device finishing callback
so that the handlers are already unregistered by the time we fully
disable clocks.

commit c128a1b0523b685c8856ddc0ac0e1caef1fdeee5 upstream.
Errata i2310[0] says, Erroneous timeout can be triggered,
if this Erroneous interrupt is not cleared then it may leads
to storm of interrupts.
Commit 9d141c1e6157 ("serial: 8250_omap: Implementation of Errata i2310")
which added the workaround but missed ensuring RX FIFO is really empty
before applying the errata workaround as recommended in the errata text.
Fix this by adding back check for UART_OMAP_RX_LVL to be 0 for
workaround to take effect.

[ Commit 75dde792d6f6c2d0af50278bd374bf0c512fe196 upstream ]
The logic in __efi_memmap_init() is shared between two different
execution flows:
- mapping the EFI memory map early or late into the kernel VA space, so
that its entries can be accessed;
- the x86 specific cloning of the EFI memory map in order to insert new
entries that are created as a result of making a memory reservation
via a call to efi_mem_reserve().
In the former case, the underlying memory containing the kernel's view
of the EFI memory map (which may be heavily modified by the kernel
itself on x86) is not modified at all, and the only thing that changes
is the virtual mapping of this memory, which is different between early
and late boot.
In the latter case, an entirely new allocation is created that carries a
new, updated version of the kernel's view of the EFI memory map. When
installing this new version, the old version will no longer be
referenced, and if the memory was allocated by the kernel, it will leak
unless it gets freed.
The logic that implements this freeing currently lives on the code path
that is shared between these two use cases, but it should only apply to
the latter. So move it to the correct spot.
While at it, drop the dummy definition for non-x86 architectures, as
that is no longer needed.

[ Commit d85e3e34940788578eeffd94e8b7e1d28e7278e9 upstream ]
Currently, the EFI_PARAVIRT flag is only used by Xen dom0 boot on x86,
even though other architectures also support pseudo-EFI boot, where the
core kernel is invoked directly and provided with a set of data tables
that resemble the ones constructed by the EFI stub, which never actually
runs in that case.
Let's fix this inconsistency, and always set this flag when booting dom0
via the EFI boot path. Note that Xen on x86 does not provide the EFI
memory map in this case, whereas other architectures do, so move the
associated EFI_PARAVIRT check into the x86 platform code.

[ Commit fdc6d38d64a20c542b1867ebeb8dd03b98829336 upstream ]
The EFI memory map is a description of the memory layout as provided by
the firmware, and only x86 manipulates it in various different ways for
its own memory bookkeeping. So let's move the memmap routines that are
only used by x86 into the x86 arch tree.

commit ab9e0c529eb7cafebdd31fe1644524e80a48b05d upstream.
If e.g. the ata_port_alloc() call in ata_host_alloc() fails, we will jump
to the err_out label, which will call devres_release_group().
devres_release_group() will trigger a call to ata_host_release().
ata_host_release() calls kfree(host), so executing the kfree(host) in
ata_host_alloc() will lead to a double free:

commit eeb25a09c5e0805d92e4ebd12c4b0ad0df1b0295 upstream.
.probe() (ahci_init_one()) calls sysfs_add_file_to_group(), however,

(The sysfs_remove_file_from_group() call in .remove() (ahci_remove_one())
does not help, as .remove() is not called on .probe() error.)
Thus, if probe() fails after the sysfs_add_file_to_group() call, the next

In the past, there were similar failures reported by CI from other IGT
tests, observed on other platforms.
Before commit 63baf4f3d587 ("drm/i915/gt: Only wait for GPU activity
before unbinding a GGTT fence"), i915_vma_revoke_fence() was waiting for
idleness of vma->active via fence_update(). That commit introduced
vma->fence->active in order for the fence_update() to be able to wait
selectively on that one instead of vma->active since only idleness of
fence registers was needed. But then, another commit 0d86ee35097a
("drm/i915/gt: Make fence revocation unequivocal") replaced the call to
fence_update() in i915_vma_revoke_fence() with only fence_write(), and
also added that GEM_BUG_ON(!i915_active_is_idle(&fence->active)) in front.
No justification was provided on why we might then expect idleness of
vma->fence->active without first waiting on it.
The issue can be potentially caused by a race among revocation of fence
registers on one side and sequential execution of signal callbacks invoked
on completion of a request that was using them on the other, still
processed in parallel to revocation of those fence registers. Fix it by
waiting for idleness of vma->fence->active in i915_vma_revoke_fence().

commit 66edf3fb331b6c55439b10f9862987b0916b3726 upstream.
In nv17_tv_get_ld_modes(), the return value of drm_mode_duplicate() is
assigned to mode, which will lead to a possible NULL pointer dereference
on failure of drm_mode_duplicate(). Add a check to avoid npd.

commit 2eabb655a968b862bc0c31629a09f0fbf3c80d51 upstream.
Syzbot is still reporting quite an old issue [1] that occurs due to
incomplete checking of present usb endpoints. As such, wrong
endpoints types may be used at urb sumbitting stage which in turn
triggers a warning in usb_submit_urb().
Fix the issue by verifying that required endpoint types are present
for both in and out endpoints, taking into account cmd endpoint type.
Unfortunately, this patch has not been tested on real hardware.

commit e587a7633dfee8987a999cf253f7c52a8e09276c upstream.
printer_read() and printer_write() guard against the race
against disable() by checking the dev->interface flag,
which in turn is guarded by a spinlock.
These functions, however, drop the lock on multiple occasions.

the lock and before doing IO.

Avoid spurious link status logs that may ultimately be wrong; for example,
if the link is set to down with the cable plugged, then the cable is
unplugged and after this the link is set to up, the last new log that is
appearing is incorrectly telling that the link is up.
In order to avoid errors, show link status logs after link_reset
processing, and in order to avoid spurious as much as possible, only show
the link loss when some link status change is detected.

commit 4241665e6ea063a9c1d734de790121a71db763fc upstream.
A read operation is happening as follows:
a) Set sensor to forced mode
b) Sensor measures values and update data registers and sleeps again
c) Read data registers
In the current implementation the read operation happens immediately
after the sensor is set to forced mode so the sensor does not have
the time to update properly the registers. This leads to the following
2 problems:
1) The first ever value which is read by the register is always wrong
2) Every read operation, puts the register into forced mode and reads
the data that were calculated in the previous conversion.
This behaviour was tested in 2 ways:
1) The internal meas_status_0 register was read before and after every
read operation in order to verify that the data were ready even before
the register was set to forced mode and also to check that after the
forced mode was set the new data were not yet ready.
2) Physically changing the temperature and measuring the temperature
This commit adds the waiting time in between the set of the forced mode
and the read of the data. The function is taken from the Bosch BME68x
Sensor API [1].

commit ab069ce125965a5e282f7b53b86aee76ab32975c upstream.
sdhci_check_ro() can call mmc_gpio_get_ro() while holding the sdhci
host->lock spinlock. That would be a problem if the GPIO access done by
mmc_gpio_get_ro() needed to sleep.
However, host->lock is not needed anyway. The mmc core ensures that host
operations do not race with each other, and asynchronous callbacks like the
interrupt handler, software timeouts, completion work etc, cannot affect
sdhci_check_ro().
So remove the locking.

commit fbd64f902b93fe9658b855b9892ae59ef6ea22b9 upstream.
mmc_of_parse() reads device property "wp-inverted" and sets
MMC_CAP2_RO_ACTIVE_HIGH if it is true. MMC_CAP2_RO_ACTIVE_HIGH is used
to invert a write-protect (AKA read-only) GPIO value.
sdhci_get_property() also reads "wp-inverted" and sets
SDHCI_QUIRK_INVERTED_WRITE_PROTECT which is used to invert the
write-protect value as well but also acts upon a value read out from the
SDHCI_PRESENT_STATE register.
Many drivers call both mmc_of_parse() and sdhci_get_property(),
so that both MMC_CAP2_RO_ACTIVE_HIGH and
SDHCI_QUIRK_INVERTED_WRITE_PROTECT will be set if the controller has
device property "wp-inverted".
Amend the logic in sdhci_check_ro() to allow for that possibility,
so that the write-protect value is not inverted twice.
Also do not invert the value if it is a negative error value. Note that
callers treat an error the same as not-write-protected, so the result is
functionally the same in that case.
Also do not invert the value if sdhci host operation ->get_ro() is used.
None of the users of that callback set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
directly or indirectly, but two do call mmc_gpio_get_ro(), so leave it to
them to deal with that if they ever set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
in the future.

[ Upstream commit 9919cce62f68e6ab68dc2a975b5dc670f8ca7d40 ]
linehandle_set_config() behaves badly when direction is not set.
The configuration validation is borrowed from linehandle_create(), where,
to verify the intent of the user, the direction must be set to in order
to effect a change to the electrical configuration of a line. But, when
applied to reconfiguration, that validation does not allow for the unset
direction case, making it possible to clear flags set previously without
specifying the line direction.
Adding to the inconsistency, those changes are not immediately applied by
linehandle_set_config(), but will take effect when the line value is next
get or set.
For example, by requesting a configuration with no flags set, an output
line with GPIOHANDLE_REQUEST_ACTIVE_LOW and GPIOHANDLE_REQUEST_OPEN_DRAIN
requested could have those flags cleared, inverting the sense of the line
and changing the line drive to push-pull on the next line value set.
Ensure the intent of the user by disallowing configurations which do not
have direction set, returning an error to userspace to indicate that the
configuration is invalid.
And, for clarity, use lflags, a local copy of gcnf.flags, throughout when
dealing with the requested flags, rather than a mixture of both.

[ Upstream commit ae6a233092747e9652eb793d92f79d0820e01c6a ]
This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1] [2].
In this case, the memory allocated to store RADEONFB_CONN_LIMIT pointers
to "drm_connector" structures can be avoided. This is because this
memory area is never accessed.
Also, in the kzalloc function, it is preferred to use sizeof(*pointer)
instead of sizeof(type) due to the type of the variable can change and
one needs not change the former (unlike the latter).
At the same time take advantage to remove the "#if 0" block, the code
where the removed memory area was accessed, and the RADEONFB_CONN_LIMIT
constant due to now is never used.

CONFIG_CPUMASK_OFFSTACK.
Use *cpumask_var API(s) to address it.

[ Upstream commit ee7860cd8b5763017f8dc785c2851fecb7a0c565 ]
The ilitek-ili9881c controls the reset GPIO using the non-sleeping
gpiod_set_value() function. This complains loudly when the GPIO
controller needs to sleep. As the caller can sleep, use
gpiod_set_value_cansleep() to fix the issue.

[ Upstream commit ad53f5f54f351e967128edbc431f0f26427172cf ]
The very first flush in any port will flush all learned addresses in all
ports. This can be observed by unplugging the cable from one port while
additional ports are connected and dumping the fdb entries.
This problem is caused by the initially wrong value programmed to the
REG_SW_LUE_CTRL_1 register. Setting SW_FLUSH_STP_TABLE and
SW_FLUSH_MSTP_TABLE bits does not have an immediate effect. It is when
ksz9477_flush_dyn_mac_table() is called then the SW_FLUSH_STP_TABLE bit
takes effect and flushes all learned entries. After that call both bits
are reset and so the next port flush will not cause such problem again.

rk3328_pin_ctrl uses type of RK3288 which has a hack in

at assume, the hack is not applicable to RK3328 as GPIO6 is not even
exist in it. So use a dedicated pinctrl type to skip this hack.

The pinmux bits for GPIO3-B1 to GPIO3-B6 pins are not explicitly
specified in RK3328 TRM, however we can get hint from pad name and its
correspinding IOMUX setting for pins in interface descriptions. The
correspinding IOMIX settings for these pins can be found in the same
row next to occurrences of following pad names in RK3328 TRM.
GPIO3-B1: IO_TSPd5m0_CIFdata5m0_GPIO3B1vccio6
GPIO3-B2: IO_TSPd6m0_CIFdata6m0_GPIO3B2vccio6
GPIO3-B3: IO_TSPd7m0_CIFdata7m0_GPIO3B3vccio6
GPIO3-B4: IO_CARDclkm0_GPIO3B4vccio6
GPIO3-B5: IO_CARDrstm0_GPIO3B5vccio6
GPIO3-B6: IO_CARDdetm0_GPIO3B6vccio6
Add pinmux data to rk3328_mux_recalced_data as mux register offset for
