b9895a4c95 scsi: 3w-xxxx: Add error handling for initialization failure in tw_probe()
[ Upstream commit 2e2fe5ac69 ]

Smatch complains that:

tw_probe() warn: missing error code 'retval'

This patch adds error checking to tw_probe() to handle initialization
failure. If tw_reset_sequence() function returns a non-zero value, the
function will return -EINVAL to indicate initialization failure.

7badf4d6f4 PCI/ASPM: Disable ASPM on MFD function removal to avoid use-after-free
[ Upstream commit 456d8aa37d ]

Struct pcie_link_state->downstream is a pointer to the pci_dev of function
0.  Previously we retained that pointer when removing function 0, and
subsequent ASPM policy changes dereferenced it, resulting in a
use-after-free warning from KASAN, e.g.:

  # echo 1 > /sys/bus/pci/devices/0000:03:00.0/remove
  # echo powersave > /sys/module/pcie_aspm/parameters/policy

  BUG: KASAN: slab-use-after-free in pcie_config_aspm_link+0x42d/0x500
  Call Trace:
   kasan_report+0xae/0xe0
   pcie_config_aspm_link+0x42d/0x500
   pcie_aspm_set_policy+0x8e/0x1a0
   param_attr_store+0x162/0x2c0
   module_attr_store+0x3e/0x80

PCIe spec r6.0, sec 7.5.3.7, recommends that software program the same ASPM
Control value in all functions of multi-function devices.

Disable ASPM and free the pcie_link_state when any child function is
removed so we can discard the dangling pcie_link_state->downstream pointer
and maintain the same ASPM Control configuration for all functions.

ac64019e4d scsi: qedf: Fix NULL dereference in error handling
[ Upstream commit f025312b08 ]

Smatch reported:

drivers/scsi/qedf/qedf_main.c:3056 qedf_alloc_global_queues()
warn: missing unwind goto?

At this point in the function, nothing has been allocated so we can return
directly. In particular the "qedf->global_queues" have not been allocated
so calling qedf_free_global_queues() will lead to a NULL dereference when
we check if (!gl[i]) and "gl" is NULL.

8e9907e921 PCI: cadence: Fix Gen2 Link Retraining process
[ Upstream commit 0e12f83023 ]

The Link Retraining process is initiated to account for the Gen2 defect in
the Cadence PCIe controller in J721E SoC. The errata corresponding to this
is i2085, documented at:
https://www.ti.com/lit/er/sprz455c/sprz455c.pdf

The existing workaround implemented for the errata waits for the Data Link
initialization to complete and assumes that the link retraining process
at the Physical Layer has completed. However, it is possible that the
Physical Layer training might be ongoing as indicated by the
PCI_EXP_LNKSTA_LT bit in the PCI_EXP_LNKSTA register.

Fix the existing workaround, to ensure that the Physical Layer training
has also completed, in addition to the Data Link initialization.

ability to specify a regulator supplying the VDDO pin for each output of

9341501e2f RDMA/bnxt_re: wraparound mbox producer index
[ Upstream commit 0af91306e1 ]

Driver is not handling the wraparound of the mbox producer index correctly.
Currently the wraparound happens once u32 max is reached.

Bit 31 of the producer index register is special and should be set
only once for the first command. Because the producer index overflow
setting bit31 after a long time, FW goes to initialization sequence
and this causes FW hang.

Fix is to wraparound the mbox producer index once it reaches u16 max.

e070120e6d drm/radeon: fix possible division-by-zero errors
[ Upstream commit 1becc57cd1 ]

Function rv740_get_decoded_reference_divider() may return 0 due to
unpredictable reference divider value calculated in
radeon_atom_get_clock_dividers(). This will lead to
division-by-zero error once that value is used as a divider
in calculating 'clk_s'.
While unlikely, this issue should nonetheless be prevented so add a
sanity check for such cases by testing 'decoded_ref' value against 0.

7e2edb84fe hwmon: (pmbus/adm1275) Fix problems with temperature monitoring on ADM1272
[ Upstream commit b153a0bb41 ]

The PMON_CONFIG register on ADM1272 is a 16 bit register. Writing a 8 bit
value into it clears the upper 8 bits of the register, resulting in
unexpected side effects. Fix by writing the 16 bit register value.

Also, it has been reported that temperature readings are sometimes widely
inaccurate, to the point where readings may result in device shutdown due
to errant overtemperature faults. Improve by enabling temperature sampling.

While at it, move the common code for ADM1272 and ADM1278 into a separate
function, and clarify in the error message that an attempt was made to
enable both VOUT and temperature monitoring.

Last but not least, return the error code reported by the underlying I2C
controller and not -ENODEV if updating the PMON_CONFIG register fails.
After all, this does not indicate that the chip is not present, but an
error in the communication with the chip.

query_device_ex is not triggered based on an op, but all drivers already

7dcb9ea3ee IB/hfi1: Fix wrong mmu_node used for user SDMA packet after invalidate
[ Upstream commit c9358de193 ]

The hfi1 user SDMA pinned-page cache will leave a stale cache entry when
the cache-entry's virtual address range is invalidated but that cache
entry is in-use by an outstanding SDMA request.

Subsequent user SDMA requests with buffers in or spanning the virtual
address range of the stale cache entry will result in packets constructed
from the wrong memory, the physical pages pointed to by the stale cache
entry.

To fix this, remove mmu_rb_node cache entries from the mmu_rb_handler
cache independent of the cache entry's refcount. Add 'struct kref
refcount' to struct mmu_rb_node and manage mmu_rb_node lifetime with
kref_get() and kref_put().

mmu_rb_node.refcount makes sdma_mmu_node.refcount redundant. Remove
'atomic_t refcount' from struct sdma_mmu_node and change sdma_mmu_node
code to use mmu_rb_node.refcount.

Move the mmu_rb_handler destructor call after a
wait-for-SDMA-request-completion call so mmu_rb_nodes that need
mmu_rb_handler's workqueue to queue themselves up for destruction from an
interrupt context may do so.

6cf8f3d690 IB/hfi1: Fix sdma.h tx->num_descs off-by-one errors
[ Upstream commit fd8958efe8 ]

Fix three sources of error involving struct sdma_txreq.num_descs.

When _extend_sdma_tx_descs() extends the descriptor array, it uses the
value of tx->num_descs to determine how many existing entries from the
tx's original, internal descriptor array to copy to the newly allocated
one.  As this value was incremented before the call, the copy loop will
access one entry past the internal descriptor array, copying its contents
into the corresponding slot in the new array.

If the call to _extend_sdma_tx_descs() fails, _pad_smda_tx_descs() then
invokes __sdma_tx_clean() which uses the value of tx->num_desc to drive a
loop that unmaps all descriptor entries in use.  As this value was
incremented before the call, the unmap loop will invoke sdma_unmap_desc()
on a descriptor entry whose contents consist of whatever random data was
copied into it during (1), leading to cascading further calls into the
kernel and driver using arbitrary data.

_sdma_close_tx() was using tx->num_descs instead of tx->num_descs - 1.

Fix all of the above by:
- Only increment .num_descs after .descp is extended.
- Use .num_descs - 1 instead of .num_descs for last .descp entry.

42b6865bf5 soc/fsl/qe: fix usb.c build errors
[ Upstream commit 7b1a78babd ]

Fix build errors in soc/fsl/qe/usb.c when QUICC_ENGINE is not set.
This happens when PPC_EP88XC is set, which selects CPM1 & CPM.
When CPM is set, USB_FSL_QE can be set without QUICC_ENGINE
being set. When USB_FSL_QE is set, QE_USB deafults to y, which
causes build errors when QUICC_ENGINE is not set. Making
QE_USB depend on QUICC_ENGINE prevents QE_USB from defaulting to y.

Fixes these build errors:

drivers/soc/fsl/qe/usb.o: in function `qe_usb_clock_set':

9c14d14066 ARM: dts: meson8: correct uart_B and uart_C clock references
[ Upstream commit 98b503c7fb ]

On Meson8 uart_B and uart_C do not work, because they are relying on
incorrect clocks. Change the references of pclk to the correct CLKID
(UART1 for uart_B and UART2 for uart_C), to allow use of the two uarts.

This was originally reported by Hans-Frieder Vogt for Meson8b [0], but
the same bug is also present in meson8.dtsi

684a2f180e ASoC: es8316: Do not set rate constraints for unsupported MCLKs
[ Upstream commit 60413129ee ]

When using the codec through the generic audio graph card, there are at
least two calls of es8316_set_dai_sysclk(), with the effect of limiting
the allowed sample rates according to the MCLK/LRCK ratios supported by
the codec:

1. During audio card setup, to set the initial MCLK - see
   asoc_simple_init_dai().

2. Before opening a stream, to update MCLK, according to the stream
   sample rate and the multiplication factor - see
   asoc_simple_hw_params().

In some cases the initial MCLK might be set to a frequency that doesn't
match any of the supported ratios, e.g. 12287999 instead of 12288000,
which is only 1 Hz below the supported clock, as that is what the
hardware reports. This creates an empty list of rate constraints, which
is further passed to snd_pcm_hw_constraint_list() via
es8316_pcm_startup(), and causes the following error on the very first
access of the sound card:

  $ speaker-test -D hw:Analog,0 -F S16_LE -c 2 -t wav
  Broken configuration for playback: no configurations available: Invalid argument
  Setting of hwparams failed: Invalid argument

Note that all subsequent retries succeed thanks to the updated MCLK set
at point 2 above, which uses a computed frequency value instead of a
reading from the hardware registers. Normally this would have mitigated
the issue, but es8316_pcm_startup() executes before the 2nd call to
es8316_set_dai_sysclk(), hence it cannot make use of the updated
constraints.

Since es8316_pcm_hw_params() performs anyway a final validation of MCLK
against the stream sample rate and the supported MCLK/LRCK ratios, fix
the issue by ensuring that sysclk_constraints list is only set when at
least one supported sample rate is autodetected by the codec.
