commit d175209be04d7d263fa1a54cde7608c706c9d0d7 upstream.
I hit a stuck relocation on btrfs/061 during my overnight testing. This
turned out to be because we had left over extent entries in our extent
root for a data reloc inode that no longer existed. This happened
because in btrfs_drop_extents() we only update refs if we have SHAREABLE
set or we are the tree_root. This regression was introduced by
aeb935a45581 ("btrfs: don't set SHAREABLE flag for data reloc tree")
where we stopped setting SHAREABLE for the data reloc tree.
The problem here is we actually do want to update extent references for
data extents in the data reloc tree, in fact we only don't want to
update extent references if the file extents are in the log tree.
Update this check to only skip updating references in the case of the
log tree.
This is relatively rare, because you have to be running scrub at the
same time, which is what btrfs/061 does. The data reloc inode has its
extents pre-allocated, and then we copy the extent into the
pre-allocated chunks. We theoretically should never be calling
btrfs_drop_extents() on a data reloc inode. The exception of course is
with scrub, if our pre-allocated extent falls inside of the block group
we are scrubbing, then the block group will be marked read only and we
will be forced to cow that extent. This means we will call
btrfs_drop_extents() on that range when we COW that file extent.
This isn't really problematic if we do this, the data reloc inode
requires that our extent lengths match exactly with the extent we are
copying, thankfully we validate the extent is correct with
get_new_location(), so if we happen to COW only part of the extent we
won't link it in when we do the relocation, so we are safe from any
other shenanigans that arise because of this interaction with scrub.

commit 4afb912f439c4bc4e6a4f3e7547f2e69e354108f upstream.
Error injection testing uncovered a case where we'd end up with a
corrupt file system with a missing extent in the middle of a file. This
occurs because the if statement to decide if we should abort is wrong.
The only way we would abort in this case is if we got a ret !=
-EOPNOTSUPP and we called from the file clone code. However the
prealloc code uses this path too. Instead we need to abort if there is
an error, and the only error we _don't_ abort on is -EOPNOTSUPP and only
if we came from the clone file code.

commit ea0f69d8211963c4b2cc1998b86779a500adb502 upstream.
Tested on SD5200T TB3 dock which has Fresco Logic FL1100 USB 3.0 Host
Controller.
Before this patch streaming video from USB cam made mouse and keyboard
connected to the same USB bus unusable. Also video was jerky.
With this patch streaming video doesn't have any effect on other
periferals and video is smooth.

commit 2e5809a4ddb15969503e43b06662a9a725f613ea upstream.
For non-4K PAGE_SIZE configs, the largest gigantic huge page size is
CONT_PMD_SHIFT order. On arm64 with 64K PAGE_SIZE, the gigantic page is
16G. Therefore, one should be able to specify 'hugetlb_cma=16G' on the
kernel command line so that one gigantic page can be allocated from CMA.
However, when adding such an option the following message is produced:
hugetlb_cma: cma area should be at least 8796093022208 MiB
This is because the calculation for non-4K gigantic page order is
incorrect in the arm64 specific routine arm64_hugetlb_cma_reserve().

This is not correct since we can get errors such as, for example, -EIO
when reading extent buffers while searching the fs/subvolume's btree.
So fix that and return the error to the caller when it is not -ENOENT.

commit b3a72ca80351917cc23f9e24c35f3c3979d3c121 upstream.
Joe reports that using a statically allocated buffer for converting CPER
error records into human readable text is probably a bad idea. Even
though we are not aware of any actual issues, a stack buffer is clearly
a better choice here anyway, so let's move the buffer into the stack
frames of the two functions that refer to it.

commit dd6dd6e3c791db7fdbc5433ec7e450717aa3a0ce upstream.
This applies a SND_PCI_QUIRK(...) to the TongFang PHxTxX1 barebone. This
fixes the issue of the internal Microphone not working after booting
another OS.
When booting a certain another OS this barebone keeps some coeff settings
even after a cold shutdown. These coeffs prevent the microphone detection
from working in Linux, making the Laptop think that there is always an
external microphone plugged-in and therefore preventing the use of the
internal one.
The relevant indexes and values where gathered by naively diff-ing and
reading a working and a non-working coeff dump.

From: Halil Pasic <[email protected]>
commit 2f9a174f918e29608564c7a4e8329893ab604fb4 upstream.
The virtio specification virtio-v1.1-cs01 states: "Transitional devices
MUST detect Legacy drivers by detecting that VIRTIO_F_VERSION_1 has not
been acknowledged by the driver." This is exactly what QEMU as of 6.1
has done relying solely on VIRTIO_F_VERSION_1 for detecting that.
However, the specification also says: "... the driver MAY read (but MUST
NOT write) the device-specific configuration fields to check that it can
support the device ..." before setting FEATURES_OK.
In that case, any transitional device relying solely on
VIRTIO_F_VERSION_1 for detecting legacy drivers will return data in
legacy format. In particular, this implies that it is in big endian
format for big endian guests. This naturally confuses the driver which
expects little endian in the modern mode.
It is probably a good idea to amend the spec to clarify that
VIRTIO_F_VERSION_1 can only be relied on after the feature negotiation
is complete. Before validate callback existed, config space was only
read after FEATURES_OK. However, we already have two regressions, so
let's address this here as well.
The regressions affect the VIRTIO_NET_F_MTU feature of virtio-net and
the VIRTIO_BLK_F_BLK_SIZE feature of virtio-blk for BE guests when
virtio 1.0 is used on both sides. The latter renders virtio-blk unusable
with DASD backing, because things simply don't work with the default.
See Fixes tags for relevant commits.
For QEMU, we can work around the issue by writing out the feature bits
with VIRTIO_F_VERSION_1 bit set. We (ab)use the finalize_features
config op for this. This isn't enough to address all vhost devices since
these do not get the features until FEATURES_OK, however it looks like
the affected devices actually never handled the endianness for legacy
mode correctly, so at least that's not a regression.
No devices except virtio net and virtio blk seem to be affected.
Long term the right thing to do is to fix the hypervisors.

commit a3fd1a986e499a06ac5ef95c3a39aa4611e7444c upstream.
We need to define the codec pin 0x1b to be the mic, but somehow
the mic doesn't support hot plugging detection, and Windows also has
this issue, so we set it to phantom headset-mic.
Also the determine_headset_type() often returns the omtp type by a
mistake when we plug a ctia headset, this makes the mic can't record
sound at all. Because most of the headset are ctia type nowadays and
some machines have the fixed ctia type audio jack, it is possible this
machine has the fixed ctia jack too. Here we set this mic jack to
fixed ctia type, this could avoid the mic type detection mistake and
make the ctia headset work stable.

commit f9a470db2736b01538ad193c316eb3f26be37d58 upstream.
fastrpc driver is using find_vma() without any protection, as a
result we see below warning due to recent patch 5b78ed24e8ec
("mm/pagemap: add mmap_assert_locked() annotations to find_vma*()")
which added mmap_assert_locked() in find_vma() function.
This bug went un-noticed in previous versions. Fix this issue by adding
required protection while calling find_vma().

commit ff0e50d3564f33b7f4b35cadeabd951d66cfc570 upstream.
The command ring pointer is located at [6:63] bits of the command
ring control register (CRCR). All the control bits like command stop,
abort are located at [0:3] bits. While aborting a command, we read the
CRCR and set the abort bit and write to the CRCR. The read will always
give command ring pointer as all zeros. So we essentially write only
the control bits. Since we split the 64 bit write into two 32 bit writes,
there is a possibility of xHC command ring stopped before the upper
dword (all zeros) is written. If that happens, xHC updates the upper
dword of its internal command ring pointer with all zeros. Next time,
when the command ring is restarted, we see xHC memory access failures.
Fix this issue by only writing to the lower dword of CRCR where all
control bits are located.

csky restore_sigcontext() blindly overwrites regs->sr with the value
it finds in sigcontext. Attacker can store whatever they want in there,
which includes things like S-bit. Userland shouldn't be able to set
that, or anything other than C flag (bit 0).
Do the same thing other architectures with protected bits in flags
register do - preserve everything that shouldn't be settable in
user mode, picking the rest from the value saved is sigcontext.

The reason for this problem is that irq has been disabled in
machine_restart() and then it calls down_interruptible() in
virt_efi_reset_system(), which would occur sleep in irq context,
it is dangerous! Commit 99409b935c9a("locking/semaphore: Add
might_sleep() to down_*() family") add might_sleep() in
down_interruptible(), so the bug info is here. down_trylock()
can solve this problem, cause there is no might_sleep.

commit be358af1191b1b2fedebd8f3421cafdc8edacc7d upstream.
I received a build failure for a new patch I'm working on the nds32
architecture, and when I went to test it, I couldn't get to my build error,
because it failed to build with a bunch of:
Error: invalid operands (*UND* and *UND* sections) for `^'
issues with various files. Those files were temporary asm files that looked
like: kernel/.tmp_mc_fork.s
I decided to look deeper, and found that the "mc" portion of that name
stood for "mcount", and was created by the recordmcount.pl script. One that
I wrote over a decade ago. Once I knew the source of the problem, I was
able to investigate it further.
The way the recordmcount.pl script works (BTW, there's a C version that
simply modifies the ELF object) is by doing an "objdump" on the object
file. Looks for all the calls to "mcount", and creates an offset of those
locations from some global variable it can use (usually a global function
name, found with <.*>:). Creates a asm file that is a table of references
to these locations, using the found variable/function. Compiles it and
links it back into the original object file. This asm file is called
".tmp_mc_<object_base_name>.s".
The problem here is that the objdump produced by the nds32 object file,
contains things that look like:
0000159a <.L3^B1>:
159a: c6 00 beqz38 $r6, 159a <.L3^B1>
159a: R_NDS32_9_PCREL_RELA .text+0x159e
159c: 84 d2 movi55 $r6, #-14
159e: 80 06 mov55 $r0, $r6
15a0: ec 3c addi10.sp #0x3c
Where ".L3^B1 is somehow selected as the "global" variable to index off of.
Then the assembly file that holds the mcount locations looks like this:
.section __mcount_loc,"a",@progbits
.align 2
.long .L3^B1 + -5522
.long .L3^B1 + -5384
.long .L3^B1 + -5270
.long .L3^B1 + -5098
.long .L3^B1 + -4970
.long .L3^B1 + -4758
.long .L3^B1 + -4122
[...]
And when it is compiled back to an object to link to the original object,
the compile fails on the "^" symbol.
Simple solution for now, is to have the perl script ignore using function
symbols that have an "^" in the name.

commit e081102f3077aa716974ccebec97003c890d5641 upstream.
Correct IRQ flag here is falling.
In Sigma-Delta devices the SDO line is also used as an interrupt.
Leaving IRQ on level instead of falling might trigger a sample read
when the IRQ is enabled, as the SDO line is already low. Not sure
if SDO line will always immediately go high in ad_sd_buffer_postenable
before the IRQ is enabled.
Also the datasheet seem to explicitly say the falling edge of the SDO
should be used as an interrupt:
>From the AD7780 datasheet: " The DOUT/Figure 22 RDY falling edge
can be used as an interrupt to a processor"

commit c2115b2b16421d93d4993f3fe4c520e91d6fe801 upstream.
Commit 7c75bde329d7 ("usb: musb: musb_dsps: request_irq() after
initializing musb") has inverted the calls to
dsps_setup_optional_vbus_irq() and dsps_create_musb_pdev() without
updating correctly the error path. dsps_create_musb_pdev() allocates and
registers a new platform device which must be unregistered and freed
with platform_device_unregister(), and this is missing upon
dsps_setup_optional_vbus_irq() error.
While on the master branch it seems not to trigger any issue, I observed
a kernel crash because of a NULL pointer dereference with a v5.10.70
stable kernel where the patch mentioned above was backported. With this
kernel version, -EPROBE_DEFER is returned the first time
dsps_setup_optional_vbus_irq() is called which triggers the probe to
error out without unregistering the platform device. Unfortunately, on
the Beagle Bone Black Wireless, the platform device still living in the
system is being used by the USB Ethernet gadget driver, which during the
boot phase triggers the crash.
My limited knowledge of the musb world prevents me to revert this commit
which was sent to silence a robot warning which, as far as I understand,
does not make sense. The goal of this patch was to prevent an IRQ to
fire before the platform device being registered. I think this cannot
ever happen due to the fact that enabling the interrupts is done by the
->enable() callback of the platform musb device, and this platform
device must be already registered in order for the core or any other
user to use this callback.
Hence, I decided to fix the error path, which might prevent future
errors on mainline kernels while also fixing older ones.

commit 5d388fa01fa6eb310ac023a363a6cb216d9d8fe9 upstream.
If a cell has 'nbits' equal to a multiple of BITS_PER_BYTE the logic
*p &= GENMASK((cell->nbits%BITS_PER_BYTE) - 1, 0);
will become undefined behavior because nbits modulo BITS_PER_BYTE is 0, and we
subtract one from that making a large number that is then shifted more than the
number of bits that fit into an unsigned long.

commit f0cb5fed37ab37f6a6c5463c5fd39b58a45670c8 upstream.
The macro MAX1X29_CHANNELS() already calls MAX1X27_CHANNELS().
Calling MAX1X27_CHANNELS() before MAX1X29_CHANNELS() in the definition
of MAX1X31_CHANNELS() declares the first 8 channels twice. So drop this
extra call from the MAX1X31 channels list definition.

The ssp_print_mcu_debug() function should return negative error codes on
error. Returning "length" is meaningless. This change does not affect
runtime because the callers only care about zero/non-zero.

commit 9b4416c5095c20e110c82ae602c254099b83b72f upstream.
In commit 10d91611f426 ("powerpc/64s: Reimplement book3s idle code in
C") kvm_start_guest() became idle_kvm_start_guest(). The old code
allocated a stack frame on the emergency stack, but didn't use the
frame to store anything, and also didn't store anything in its caller's
frame.
idle_kvm_start_guest() on the other hand is written more like a normal C
function, it creates a frame on entry, and also stores CR/LR into its
callers frame (per the ABI). The problem is that there is no caller
frame on the emergency stack.
The emergency stack for a given CPU is allocated with:
paca_ptrs[i]->emergency_sp = alloc_stack(limit, i) + THREAD_SIZE;
So emergency_sp actually points to the first address above the emergency
stack allocation for a given CPU, we must not store above it without
first decrementing it to create a frame. This is different to the
regular kernel stack, paca->kstack, which is initialised to point at an
initial frame that is ready to use.
idle_kvm_start_guest() stores the backchain, CR and LR all of which
write outside the allocation for the emergency stack. It then creates a
stack frame and saves the non-volatile registers. Unfortunately the
frame it creates is not large enough to fit the non-volatiles, and so
the saving of the non-volatile registers also writes outside the
emergency stack allocation.
The end result is that we corrupt whatever is at 0-24 bytes, and 112-248
bytes above the emergency stack allocation.
In practice this has gone unnoticed because the memory immediately above
the emergency stack happens to be used for other stack allocations,
either another CPUs mc_emergency_sp or an IRQ stack. See the order of
calls to irqstack_early_init() and emergency_stack_init().
The low addresses of another stack are the top of that stack, and so are
only used if that stack is under extreme pressue, which essentially
never happens in practice - and if it did there's a high likelyhood we'd
crash due to that stack overflowing.
Still, we shouldn't be corrupting someone else's stack, and it is purely
luck that we aren't corrupting something else.
To fix it we save CR/LR into the caller's frame using the existing r1 on
entry, we then create a SWITCH_FRAME_SIZE frame (which has space for
pt_regs) on the emergency stack with the backchain pointing to the
existing stack, and then finally we switch to the new frame on the
emergency stack.

commit 55a9968c7e139209a9e93d4ca4321731bea5fc95 upstream.
The commit 15add06841a3 ("gpio: pca953x: add ->set_config implementation")
introduced support for bias setting. However this, due to being half-baked,
brought potential issues:
- the turning bias via disabling makes the pin floating for a while;
- once enabled, bias can't be disabled.
Fix all these by adding support for bias disabling and move the disabling
part under the corresponding conditional.
While at it, add support for default setting, since it's cheap to add.

commit 0bc73ad46a76ed6ece4dcacb28858e7b38561e1c upstream.
Due to current HW arch limitations, RX-FCS (scattering FCS frame field
to software) and RX-port-timestamp (improved timestamp accuracy on the
receive side) can't work together.
RX-port-timestamp is not controlled by the user and it is enabled by
default when supported by the HW/FW.
This patch sets RX-port-timestamp opposite to RX-FCS configuration.

commit cdeb5d7d890e14f3b70e8087e745c4a6a7d9f337 upstream.
We call idle_kvm_start_guest() from power7_offline() if the thread has
been requested to enter KVM. We pass it the SRR1 value that was returned
from power7_idle_insn() which tells us what sort of wakeup we're
processing.
Depending on the SRR1 value we pass in, the KVM code might enter the
guest, or it might return to us to do some host action if the wakeup
requires it.
If idle_kvm_start_guest() is able to handle the wakeup, and enter the
guest it is supposed to indicate that by returning a zero SRR1 value to
us.
That was the behaviour prior to commit 10d91611f426 ("powerpc/64s:
Reimplement book3s idle code in C"), however in that commit the
handling of SRR1 was reworked, and the zeroing behaviour was lost.
Returning from idle_kvm_start_guest() without zeroing the SRR1 value can
confuse the host offline code, causing the guest to crash and other
weirdness.

commit a2d859e3fc97e79d907761550dbc03ff1b36479c upstream.
sctp_make_strreset_req() makes repeated calls to sctp_addto_chunk()
which will automatically account for padding on each call. inreq and
outreq are already 4 bytes aligned, but the payload is not and doing
SCTP_PAD4(a + b) (which _sctp_make_chunk() did implicitly here) is
different from SCTP_PAD4(a) + SCTP_PAD4(b) and not enough. It led to
possible attempt to use more buffer than it was allocated and triggered
a BUG_ON.

commit 98e96cf80045a383fcc47c58dd4e87b3ae587b3e upstream.
fw_devlink could end up creating device links for bus only devices.
However, bus only devices don't get probed and can block probe() or
sync_state() [1] call backs of other devices. To avoid this, probe these
devices using the simple-pm-bus driver.
However, there are instances of devices that are not simple buses (they get
probed by their specific drivers) that also list the "simple-bus" (or other
bus only compatible strings) in their compatible property to automatically
populate their child devices. We still want these devices to get probed by
their specific drivers. So, we make sure this driver only probes devices
that are only buses.

commit 711885906b5c2df90746a51f4cd674f1ab9fbb1d upstream.
This Kconfig option was added initially so that memory encryption is
enabled by default on machines which support it.
However, devices which have DMA masks that are less than the bit
position of the encryption bit, aka C-bit, require the use of an IOMMU
or the use of SWIOTLB.
If the IOMMU is disabled or in passthrough mode, the kernel would switch
to SWIOTLB bounce-buffering for those transfers.
In order to avoid that,
2cc13bb4f59f ("iommu: Disable passthrough mode when SME is active")
disables the default IOMMU passthrough mode so that devices for which the
default 256K DMA is insufficient, can use the IOMMU instead.
However 2, there are cases where the IOMMU is disabled in the BIOS, etc.
(think the usual hardware folk "oops, I dropped the ball there" cases) or a
driver doesn't properly use the DMA APIs or a device has a firmware or
hardware bug, e.g.:
ea68573d408f ("drm/amdgpu: Fail to load on RAVEN if SME is active")
However 3, in the above GPU use case, there are APIs like Vulkan and
some OpenGL/OpenCL extensions which are under the assumption that
user-allocated memory can be passed in to the kernel driver and both the
GPU and CPU can do coherent and concurrent access to the same memory.
That cannot work with SWIOTLB bounce buffers, of course.
So, in order for those devices to function, drop the "default y" for the
SME by default active option so that users who want to have SME enabled,
will need to either enable it in their config or use "mem_encrypt=on" on
the kernel command line.

commit 075da584bae2da6a37428d59a477b6bdad430ac3 upstream.
Some old IPs do not provide the hardware feature register.
On these IPs, this register is read 0x00000000.
In old driver version, this feature was handled but a regression came
with the commit f10a6a3541b4 ("stmmac: rework get_hw_feature function").
Indeed, this commit removes the return value in dma->get_hw_feature().
This return value was used to indicate the validity of retrieved
information and used later on in stmmac_hw_init() to override
priv->plat data if this hardware feature were valid.
This patch restores the return code in ->get_hw_feature() in order
to indicate the hardware feature validity and override priv->plat
data only if this hardware feature is valid.

commit 94b960b9deffc02fc0747afc01f72cc62ab099e3 upstream.
Prior to this patch in case mlx5_core_destroy_cq() failed it returns
without completing all destroy operations and that leads to memory leak.
Instead, complete the destroy flow before return error.
Also move mlx5_debug_cq_remove() to the beginning of mlx5_core_destroy_cq()
to be symmetrical with mlx5_core_create_cq().
kmemleak complains on:

commit 89a86da5cb8e0ee153111fb68a719d31582c206b upstream.
IRQ type in ad_sigma_delta_info struct was missing.
In Sigma-Delta devices the SDO line is also used as an interrupt.
Leaving IRQ on level instead of falling might trigger a sample read
when the IRQ is enabled, as the SDO line is already low. Not sure
if SDO line will always immediately go high in ad_sd_buffer_postenable
before the IRQ is enabled.
Also the datasheet seem to explicitly say the falling edge of the SDO
should be used as an interrupt:
>From the AD7192 datasheet: "The DOUT/RDY falling edge can be used
as an interrupt to a processor,"

commit ef1100ef20f29aec4e62abeccdb5bdbebba1e378 upstream.
When the ksz module is installed and removed using rmmod, kernel crashes
with null pointer dereferrence error. During rmmod, ksz_switch_remove
function tries to cancel the mib_read_workqueue using
cancel_delayed_work_sync routine and unregister switch from dsa.
During dsa_unregister_switch it calls ksz_mac_link_down, which in turn
reschedules the workqueue since mib_interval is non-zero.
Due to which queue executed after mib_interval and it tries to access
dp->slave. But the slave is unregistered in the ksz_switch_remove
function. Hence kernel crashes.
To avoid this crash, before canceling the workqueue, resetted the
mib_interval to 0.
v1 -> v2:
-Removed the if condition in ksz_mib_read_work

commit 6f779e1d359b8d5801f677c1d49dcfa10bf95674 upstream.
When an interrupt is passed through, the KVM XIVE device calls the
set_vcpu_affinity() handler which raises the P bit to mask the
interrupt and to catch any in-flight interrupts while routing the
interrupt to the guest.
On the guest side, drivers (like some Intels) can request at probe
time some MSIs and call synchronize_irq() to check that there are no
in flight interrupts. This will call the XIVE get_irqchip_state()
handler which will always return true as the interrupt P bit has been
set on the host side and lock the CPU in an infinite loop.
Fix that by discarding disabled interrupts in get_irqchip_state().

What apparently happened is that an old cleanup changed the calling
conventions for s2io_set_mac_addr() from taking an ethernet address
as a character array to taking a struct sockaddr, but one of the
callers was not changed at the same time.
Change it to instead call the low-level do_s2io_prog_unicast() function
that still takes the old argument type.

commit 14eb0cb4e9a7323c8735cf6c681ed8423ce6ae06 upstream.
In theory a context can be destroyed and a new one allocated at the same
address, making the pointer comparision to detect when we don't need to
update the current pagetables invalid. Instead assign a sequence number
to each context on creation, and use this for the check.

commit 14132690860e4d06aa3e1c4d7d8e9866ba7756dd upstream.
Introduction of lockless subqueues broke the class statistics.
Before the change stats were accumulated in `bstats' and `qstats'
on the stack which was then copied to struct gnet_dump.
After the change the `bstats' and `qstats' are initialized to 0
and never updated, yet still fed to gnet_dump. The code updates
the global qdisc->cpu_bstats and qdisc->cpu_qstats instead,
clobbering them. Most likely a copy-paste error from the code in
mqprio_dump().
__gnet_stats_copy_basic() and __gnet_stats_copy_queue() accumulate
the values for per-CPU case but for global stats they overwrite
the value, so only stats from the last loop iteration / tc end up
in sch->[bq]stats.
Use the on-stack [bq]stats variables again and add the stats manually
in the global case.

commit f729a592adb6760013c3e48622a5bf256b992452 upstream.
SYNC_STATE_ONLY device links intentionally allow cycles because cyclic
sync_state() dependencies are valid and necessary.
However a SYNC_STATE_ONLY device link where the consumer and the supplier
are the same device is pointless because the device link would be deleted
as soon as the device probes (because it's also the consumer) and won't
affect when the sync_state() callback is called. It's a waste of CPU cycles
and memory to create this device link. So reject any attempts to create
such a device link.

commit d9b7748ffc45250b4d7bcf22404383229bc495f5 upstream.
The number of correctable errors is displayed as uncorrectable
errors because the "SBE" error count is passed to both calls of
edac_mc_handle_error().
Pass the correct uncorrectable error count to the second
edac_mc_handle_error() call when logging uncorrectable errors.

commit 97794170b696856483f74b47bfb6049780d2d3a0 upstream.
In commit e11f5bd8228f ("drm: Add support for DP 1.4 Compliance edid
corruption test") the function connector_bad_edid() started assuming
that the memory for the EDID passed to it was big enough to hold
`edid[0x7e] + 1` blocks of data (1 extra for the base block). It
completely ignored the fact that the function was passed `num_blocks`
which indicated how much memory had been allocated for the EDID.
Let's fix this by adding a bounds check.
This is important for handling the case where there's an error in the
first block of the EDID. In that case we will call
connector_bad_edid() without having re-allocated memory based on
`edid[0x7e]`.

When skb_match is NULL, it means we received a PTP IRQ for a timestamp
ID that the kernel has no idea about, since there is no skb in the
timestamping queue with that timestamp ID.
This is a grave error and not something to just "continue" over.
So print a big warning in case this happens.
Also, move the check above ocelot_get_hwtimestamp(), there is no point
in reading the full 64-bit current PTP time if we're not going to do
anything with it anyway for this skb.

commit 5c976a56570f29aaf4a2f9a1bf99789c252183c9 upstream.
Bridging, and possibly other upper stack gizmos, adds the
lower device's netdev->dev_addr to its own uc list, and
then requests it be deleted when the upper bridge device is
removed. This delete request also happens with the bridging
vlan_filtering is enabled and then disabled.
Bonding has a similar behavior with the uc list, but since it
also uses set_mac to manage netdev->dev_addr, it doesn't have
the same the failure case.
Because we store our netdev->dev_addr in our uc list, we need
to ignore the delete request from dev_uc_sync so as to not
lose the address and all hope of communicating. Note that
ndo_set_mac_address is expressly changing netdev->dev_addr,
so no limitation is set there.

commit 4a3e0aeddf091f00974b02627c157843ce382a24 upstream.
mv88e6xxx_port_ppu_updates() interpretes data in the PORT_STS
register incorrectly for internal ports (ie no PPU). In these
cases, the PHY_DETECT bit indicates link status. This results
in forcing the MAC state whenever the PHY link goes down which
is not intended. As a side effect, LED's configured to show
link status stay lit even though the physical link is down.
Add a check in mac_link_down and mac_link_up to see if it
concerns an external port and only then, look at PPU status.

commit 9b024201693e397441668cca0d2df7055fe572eb upstream.
Change kstrtou32() argument 'base' to be zero instead of 'len'.
It works by chance for setting one bit value, but it is not supposed to
work in case value passed to mlxreg_io_attr_store() is greater than 1.
It works for example, for:
echo 1 > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable
But it will fail for:
echo n > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable,
where n > 1.
The flow for input buffer conversion is as below:
_kstrtoull(const char *s, unsigned int base, unsigned long long *res)
calls:
rv = _parse_integer(s, base, &_res);
For the second case, where n > 1:
- _parse_integer() converts 's' to 'val'.
For n=2, 'len' is set to 2 (string buffer is 0x32 0x0a), for n=3
'len' is set to 3 (string buffer 0x33 0x0a), etcetera.
- 'base' is equal or greater then '2' (length of input buffer).
As a result, _parse_integer() exits with result zero (rv):
rv = 0;
while (1) {
...
if (val >= base)-> (2 >= 2)
break;
...
rv++;
...
}
And _kstrtoull() in their turn will fail:
if (rv == 0)

From: Ido Schimmel <[email protected]>
commit 332fdf951df8b870e3da86b122ae304e2aabe88c upstream.
Currently, mlxsw allows cooling states to be set above the maximum
cooling state supported by the driver:
# cat /sys/class/thermal/thermal_zone2/cdev0/type
mlxsw_fan
# cat /sys/class/thermal/thermal_zone2/cdev0/max_state
10
# echo 18 > /sys/class/thermal/thermal_zone2/cdev0/cur_state
# echo $?
0
This results in out-of-bounds memory accesses when thermal state
transition statistics are enabled (CONFIG_THERMAL_STATISTICS=y), as the
transition table is accessed with a too large index (state) [1].
According to the thermal maintainer, it is the responsibility of the
driver to reject such operations [2].
Therefore, return an error when the state to be set exceeds the maximum
cooling state supported by the driver.
To avoid dead code, as suggested by the thermal maintainer [3],
partially revert commit a421ce088ac8 ("mlxsw: core: Extend cooling
device with cooling levels") that tried to interpret these invalid
cooling states (above the maximum) in a special way. The cooling levels
array is not removed in order to prevent the fans going below 20% PWM,
which would cause them to get stuck at 0% PWM.

commit 60d950f443a52d950126ad664fbd4a1eb8353dc9 upstream.
In commit 74fc4f828769 ("net: Fix offloading indirect devices dependency
on qdisc order creation"), it adds a process to trigger the callback to
setup the bo callback when the driver regists a callback.
In our current implement, we are not ready to run the callback when nfp
call the function flow_indr_dev_register, then there will be error
