b390441318 drm/amdgpu: skip amdgpu_device_cache_pci_state under sriov
[ Upstream commit afe260df55ac280cd56306248cb6d8a6b0db095c ]

Under sriov, host driver will save and restore vf pci cfg space during
reset. And during device init, under sriov, pci_restore_state happens after
fullaccess released, and it can have race condition with mmio protection
enable from host side leading to missing interrupts.

So skip amdgpu_device_cache_pci_state for sriov.

aeaec85841 drm/radeon/r600_cs: Fix possible int overflow in r600_packet3_check()
[ Upstream commit a1e2da6a5072f8abe5b0feaa91a5bcd9dc544a04 ]

It is possible, although unlikely, that an integer overflow will occur
when the result of radeon_get_ib_value() is shifted to the left.

Avoid it by casting one of the operands to larger data type (u64).

[ Upstream commit 361ebf5ef843b0aa1704c72eb26b91cf76c3c5b7 ]

Add quirk orientation for AYA NEO 2. The name appears without spaces in
DMI strings. That made it difficult to reuse the 2021 match. Also the
display is larger in resolution.

Tested by the JELOS team that has been patching their own kernel for a
while now and confirmed by users in the AYA NEO and ChimeraOS discord
servers.

84e89a5746 drm/vc4: hvs: Set AXI panic modes for the HVS
[ Upstream commit 014eccc9da7bfc76a3107fceea37dd60f1d63630 ]

The HVS can change AXI request mode based on how full the COB
FIFOs are.
Until now the vc4 driver has been relying on the firmware to
have set these to sensible values.

With HVS channel 2 now being used for live video, change the
panic mode for all channels to be explicitly set by the driver,
and the same for all channels.

ab4a8be7cb iommu/arm-smmu: Defer probe of clients after smmu device bound
commit 229e6ee43d2a160a1592b83aad620d6027084aad upstream.

Null pointer dereference occurs due to a race between smmu
driver probe and client driver probe, when of_dma_configure()
for client is called after the iommu_device_register() for smmu driver
probe has executed but before the driver_bound() for smmu driver
has been called.

Following is how the race occurs:

T1:Smmu device probe		T2: Client device probe

really_probe()
arm_smmu_device_probe()
iommu_device_register()
					really_probe()
					platform_dma_configure()
					of_dma_configure()
					of_dma_configure_id()
					of_iommu_configure()
					iommu_probe_device()
					iommu_init_device()
					arm_smmu_probe_device()
					arm_smmu_get_by_fwnode()
						driver_find_device_by_fwnode()
						driver_find_device()
						next_device()
						klist_next()
						    /* null ptr
						       assigned to smmu */
					/* null ptr dereference
					   while smmu->streamid_mask */
driver_bound()
	klist_add_tail()

When this null smmu pointer is dereferenced later in
arm_smmu_probe_device, the device crashes.

Fix this by deferring the probe of the client device
until the smmu device has bound to the arm smmu driver.

ed86ece6ba mmc: core: Further prevent card detect during shutdown
commit 87a0d90fcd31c0f36da0332428c9e1a1e0f97432 upstream.

Disabling card detect from the host's ->shutdown_pre() callback turned out
to not be the complete solution. More precisely, beyond the point when the
mmc_bus->shutdown() has been called, to gracefully power off the card, we
need to prevent card detect. Otherwise the mmc_rescan work may poll for the
card with a CMD13, to see if it's still alive, which then will fail and
hang as the card has already been powered off.

To fix this problem, let's disable mmc_rescan prior to power off the card
during shutdown.

6ee2f7bb0c mmc: sdhci-pci: Add DMI quirk for missing CD GPIO on Vexia Edu Atla 10 tablet
commit 7f0fa47ceebcff0e3591bb7e32a71a2cd7846149 upstream.

The Vexia Edu Atla 10 tablet distributed to schools in the Spanish
Andalucía region has no ACPI fwnode associated with the SDHCI controller
for its microsd-slot and thus has no ACPI GPIO resource info.

This causes the following error to be logged and the slot to not work:
[   10.572113] sdhci-pci 0000:00:12.0: failed to setup card detect gpio

Add a DMI quirk table for providing gpiod_lookup_tables with manually
provided CD GPIO info and use this DMI table to provide the CD GPIO info
on this tablet. This fixes the microsd-slot not working.

5c31924089 regmap: detach regmap from dev on regmap_exit
commit 3061e170381af96d1e66799d34264e6414d428a7 upstream.

At the end of __regmap_init(), if dev is not NULL, regmap_attach_dev()
is called, which adds a devres reference to the regmap, to be able to
retrieve a dev's regmap by name using dev_get_regmap().

When calling regmap_exit, the opposite does not happen, and the
reference is kept until the dev is detached.

Add a regmap_detach_dev() function and call it in regmap_exit() to make
sure that the devres reference is not kept.

commit 78ac1c3558810486d90aa533b0039aa70487a3da upstream.

The function silently assumed that signaling was already enabled for the
dma_fence_array. This meant that without enabling signaling first we would
never see forward progress.

Fix that by falling back to testing each individual fence when signaling
isn't enabled yet.

v2: add the comment suggested by Boris why this is done this way
v3: fix the underflow pointed out by Tvrtko
v4: atomic_read_acquire() as suggested by Tvrtko

2491c1be36 bcache: revert replacing IS_ERR_OR_NULL with IS_ERR again
commit b2e382ae12a63560fca35050498e19e760adf8c0 upstream.

Commit 028ddcac477b ("bcache: Remove unnecessary NULL point check in
node allocations") leads a NULL pointer deference in cache_set_flush().

1721         if (!IS_ERR_OR_NULL(c->root))
1722                 list_add(&c->root->list, &c->btree_cache);

>From the above code in cache_set_flush(), if previous registration code
fails before allocating c->root, it is possible c->root is NULL as what
it is initialized. __bch_btree_node_alloc() never returns NULL but
c->root is possible to be NULL at above line 1721.

This patch replaces IS_ERR() by IS_ERR_OR_NULL() to fix this.

commit 07c903db0a2ff84b68efa1a74a4de353ea591eb0 upstream.

System crash is observed with stack trace warning of use after
free. There are 2 signals to tell dpc_thread to terminate (UNLOADING
flag and kthread_stop).

On setting the UNLOADING flag when dpc_thread happens to run at the time
and sees the flag, this causes dpc_thread to exit and clean up
itself. When kthread_stop is called for final cleanup, this causes use
after free.

Remove UNLOADING signal to terminate dpc_thread.  Use the kthread_stop
as the main signal to exit dpc_thread.

commit 4812b7796c144f63a1094f79a5eb8fbdad8d7ebc upstream.

NVMe controller fails to send connect command due to failure to locate
hw context buffer for NVMe queue 0 (blk_mq_hw_ctx, hctx_idx=0). The
cause of the issue is NPIV host did not initialize the vha->irq_offset
field.  This field is given to blk-mq (blk_mq_pci_map_queues) to help
locate the beginning of IO Queues which in turn help locate NVMe queue
0.

Initialize this field to allow NVMe to work properly with NPIV host.

commit 4962ee045d8f06638714d801ab0fb72f89c16690 upstream.

Currently "timeout-sec" Device Tree property is being silently ignored:
even though watchdog_init_timeout() is being used, the driver always passes
"heartbeat" == DEFAULT_HEARTBEAT == 60 as argument.

Fix this by setting struct watchdog_device::timeout to DEFAULT_HEARTBEAT
and passing real module parameter value to watchdog_init_timeout() (which
may now be 0 if not specified).

If we remove the module which will call mpc52xx_spi_remove
it will free 'ms' through spi_unregister_controller.
while the work ms->work will be used. The sequence of operations
that may lead to a UAF bug.

Fix it by ensuring that the work is canceled before proceeding with
the cleanup in mpc52xx_spi_remove.

64bc2c4ae5 i3c: master: Fix dynamic address leak when 'assigned-address' is present
[ Upstream commit 851bd21cdb55e727ab29280bc9f6b678164f802a ]

If the DTS contains 'assigned-address', a dynamic address leak occurs
during hotjoin events.

Assume a device have assigned-address 0xb.
  - Device issue Hotjoin
  - Call i3c_master_do_daa()
  - Call driver xxx_do_daa()
  - Call i3c_master_get_free_addr() to get dynamic address 0x9
  - i3c_master_add_i3c_dev_locked(0x9)
  -     expected_dyn_addr  = newdev->boardinfo->init_dyn_addr (0xb);
  -     i3c_master_reattach_i3c_dev(newdev(0xb), old_dyn_addr(0x9));
  -         if (dev->info.dyn_addr != old_dyn_addr &&
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 0xb != 0x9 -> TRUE
                (!dev->boardinfo ||
                 ^^^^^^^^^^^^^^^ ->  FALSE
                 dev->info.dyn_addr != dev->boardinfo->init_dyn_addr)) {
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                 0xb != 0xb      ->  FALSE
                 ...
                 i3c_bus_set_addr_slot_status(&master->bus, old_dyn_addr,
                                                     I3C_ADDR_SLOT_FREE);
		 ^^^
                 This will be skipped. So old_dyn_addr never free
            }

  - i3c_master_get_free_addr() will return increased sequence number.

Remove dev->info.dyn_addr != dev->boardinfo->init_dyn_addr condition check.
dev->info.dyn_addr should be checked before calling this function because
i3c_master_setnewda_locked() has already been called and the target device
has already accepted dyn_addr. It is too late to check if dyn_addr is free
in i3c_master_reattach_i3c_dev().

Add check to ensure expected_dyn_addr is free before
i3c_master_setnewda_locked().

a7450ab38f i3c: master: Extend address status bit to 4 and add I3C_ADDR_SLOT_EXT_DESIRED
[ Upstream commit 2f552fa280590e61bd3dbe66a7b54b99caa642a4 ]

Extend the address status bit to 4 and introduce the
I3C_ADDR_SLOT_EXT_DESIRED macro to indicate that a device prefers a
specific address. This is generally set by the 'assigned-address' in the
device tree source (dts) file.

 ┌────┬─────────────┬───┬─────────┬───┐
 │S/Sr│ 7'h7E RnW=0 │ACK│ ENTDAA  │ T ├────┐
 └────┴─────────────┴───┴─────────┴───┘    │
 ┌─────────────────────────────────────────┘
 │  ┌──┬─────────────┬───┬─────────────────┬────────────────┬───┬─────────┐
 └─►│Sr│7'h7E RnW=1  │ACK│48bit UID BCR DCR│Assign 7bit Addr│PAR│ ACK/NACK│
    └──┴─────────────┴───┴─────────────────┴────────────────┴───┴─────────┘

Some master controllers (such as HCI) need to prepare the entire above
transaction before sending it out to the I3C bus. This means that a 7-bit
dynamic address needs to be allocated before knowing the target device's
UID information.

However, some I3C targets may request specific addresses (called as
"init_dyn_addr"), which is typically specified by the DT-'s
assigned-address property. Lower addresses having higher IBI priority. If
it is available, i3c_bus_get_free_addr() preferably return a free address
that is not in the list of desired addresses (called as "init_dyn_addr").
This allows the device with the "init_dyn_addr" to switch to its
"init_dyn_addr" when it hot-joins the I3C bus. Otherwise, if the
"init_dyn_addr" is already in use by another I3C device, the target device
will not be able to switch to its desired address.

If the previous step fails, fallback returning one of the remaining
unassigned address, regardless of its state in the desired list.

The address slot bitmap is an array of unsigned long's which are the
same size as an int on 32-bit platforms but not 64-bit.  Loading the
bitmap into an int could result in the incorrect status being returned
for a slot and slots being reported as the wrong status.

Commit 43645ce03e00 ("qed: Populate nvm image attribute shadow.")
added support for populating flash image attributes, notably
"num_images". However, some cards were not able to return this
information. In such cases, the driver would return EINVAL, causing the
driver to exit.

Add check to return EOPNOTSUPP instead of EINVAL when the card is not
able to return these information. The caller function already handles
EOPNOTSUPP without error.

Commit da23b6faa8bf ("watchdog: iTCO: Add support for Cannon Lake

value comparison for update_no_reboot_bit() call causing following

   ...

and this can lead to unexpected NMIs later during regular
crashkernel's workflow because of watchdog probe call failures.

This change masks NMI_NOW bit for TCO1_CNT register values to
avoid unexpected NMI_NOW bit inversions.

K2G forwards the error triggered by a link-down state (e.g., no connected

these errors are reported as an SError at system level, which is fatal and
hangs the system.

946d0edf40 octeontx2-pf: Fix out-of-bounds read in otx2_get_fecparam()
commit 93efb0c656837f4a31d7cc6117a7c8cecc8fadac upstream.

Code at line 967 implies that rsp->fwdata.supported_fec may be up to 4:

 967: if (rsp->fwdata.supported_fec <= FEC_MAX_INDEX)

If rsp->fwdata.supported_fec evaluates to 4, then there is an
out-of-bounds read at line 971 because fec is an array with
a maximum of 4 elements:

 954         const int fec[] = {
 955                 ETHTOOL_FEC_OFF,
 956                 ETHTOOL_FEC_BASER,
 957                 ETHTOOL_FEC_RS,
 958                 ETHTOOL_FEC_BASER | ETHTOOL_FEC_RS};
 959 #define FEC_MAX_INDEX 4

 971: fecparam->fec = fec[rsp->fwdata.supported_fec];

Fix this by properly indexing fec[] with rsp->fwdata.supported_fec - 1.
In this case the proper indexes 0 to 3 are used when
rsp->fwdata.supported_fec evaluates to a range of 1 to 4, correspondingly.
