If the device tree is incorrectly configured, and attempts to
define a "no-map" reserved memory that overlaps with the kernel
data/code, the kernel would crash quickly after boot, with no
obvious clue about the nature of the issue.
And we declare a no-map shared-dma-pool region at a fixed address
within that range:
mem_reserved: mem_region {
compatible = "shared-dma-pool";
reg = <0 0x40000000 0 0x01A00000>;
no-map;
};
To fix this, when removing memory regions at early boot (which is
what "no-map" regions do), we need to make sure that the memory
is not already reserved. If we do, __reserved_mem_reserve_reg
will throw an error:
[ 0.000000] OF: fdt: Reserved memory: failed to reserve memory
for node 'mem_region': base 0x0000000040000000, size 26 MiB
and the code that will try to use the region should also fail,
later on.
We do not do anything for non-"no-map" regions, as memblock
explicitly allows reserved regions to overlap, and the commit
that this fixes removed the check for that precise reason.

On Intel Tangier B0 and Anniedale the interrupt line, disregarding
to have different numbers, is shared between HSU DMA and UART IPs.
Thus on such SoCs we are expecting that IRQ handler is called in
UART driver only. hsu_pci_irq was handling the spurious interrupt
from HSU DMA by returning immediately. This wastes CPU time and
since HSU DMA and HSU UART interrupt occur simultaneously they race
to be handled causing delay to the HSU UART interrupt handling.
Fix this by disabling the interrupt entirely.
When building with CONFIG_UBSAN_UNSIGNED_OVERFLOW, clang decides not to
inline gpi_update_reg, which causes a linkage failure around __bad_mask:
ld.lld: error: undefined symbol: __bad_mask
>>> referenced by bitfield.h:119 (include/linux/bitfield.h:119)
>>> dma/qcom/gpi.o:(gpi_update_reg) in archive drivers/built-in.a
>>> referenced by bitfield.h:119 (include/linux/bitfield.h:119)
>>> dma/qcom/gpi.o:(gpi_update_reg) in archive drivers/built-in.a
If gpi_update_reg is not inlined, the mask value will not be known at
compile time so the check in field_multiplier stays in the final
object file, causing the above linkage failure. Always inline
gpi_update_reg so that this check can never fail.
During connection setup, the application may choose to zero-size inbound
and outbound READ queues, as well as the Receive queue. This patch fixes
handling of zero-sized queues, but not prevents it.
Kamal Heib says in an initial error report:
When running the blktests over siw the following shift-out-of-bounds is
reported, this is happening because the passed IRD or ORD from the ulp
could be zero which will lead to unexpected behavior when calling
roundup_pow_of_two(), fix that by blocking zero values of ORD or IRD.
Prevent invalid (0, 0) inputs to hid-core's snto32() function.
Maybe it is just the dummy device here that is causing this, but
there are hundreds of calls to snto32(0, 0). Having n (bits count)
of 0 is causing the current UBSAN trap with a shift value of
0xffffffff (-1, or n - 1 in this function).
Either of the value to shift being 0 or the bits count being 0 can be
handled by just returning 0 to the caller, avoiding the following
complex shift + OR operations:
return value & (1 << (n - 1)) ? value | (~0U << n) : value;

The code prior to 311e305fdb4e ("drm/vc4: hdmi: Implement a register
layout abstraction") was relying on the fact that the register offset
was incremented by 4 for each readl call. That worked since the register
width is 4 bytes.
However, since that commit the HDMI_READ macro is now taking an enum,
and the offset doesn't increment by 4 but 1 now. Divide the index by 4
to fix this.

When a msg is retried because the lower ap layer returns -EAGAIN
there is a retry limit (currently 10). When this limit is reached
the last return code from the lower layer is returned, causing
the userspace to get -1 on the ioctl with errno EAGAIN.
This EAGAIN is misleading here. After 10 retry attempts the
userspace should receive a clear failure indication like EINVAL
or EIO or ENODEV. However, the reason why these retries all
fail is unclear. On an invalid message EINVAL would be returned
by the lower layer, and if devices go away or are not available
an ENODEV is seen. So this patch now reworks the retry loops
to return EIO to userspace when the retry limit is reached.

start = end + 1;
if (start < page_end)
goto again;
}
The behavior is indeed necessary for the incoming subpage support, but
when it iterates through all the ordered extents, it also resets the
search range @start.
This means, for the following cases, we can double account the ordered
extents, causing its bytes_left underflow:
As the first iteration will find ordered extent (OE) 1, which doesn't
cover the full page, thus after cleanup code, we need to retry again.
But again label will reset start to page_start, and we got OE 1 again,
which causes double accounting on OE 1, and cause OE 1's byte_left to
underflow.
This problem can only happen for subpage case, as for regular sectorsize
== PAGE_SIZE case, we will always find a OE ends at or after page end,
thus no way to trigger the problem.
Move the again label after start = page_start. There will be more
comprehensive rework to convert the open coded loop to a proper while
loop for subpage support.

When channel->device_obj is non-NULL, vmbus_onoffer_rescind() could
invoke put_device(), that will eventually release the device and free

Don't clear the SME C-bit when reading a guest PDPTR, as the GPA (CR3) is
in the guest domain.
Barring a bizarre paravirtual use case, this is likely a benign bug. SME
is not emulated by KVM, loading SEV guest PDPTRs is doomed as KVM can't
use the correct key to read guest memory, and setting guest MAXPHYADDR
higher than the host, i.e. overlapping the C-bit, would cause faults in
the guest.
Note, for SEV guests, stripping the C-bit is technically aligned with CPU
behavior, but for KVM it's the greater of two evils. Because KVM doesn't
have access to the guest's encryption key, ignoring the C-bit would at
best result in KVM reading garbage. By keeping the C-bit, KVM will
fail its read (unless userspace creates a memslot with the C-bit set).
The guest will still undoubtedly die, as KVM will use '0' for the PDPTR
value, but that's preferable to interpreting encrypted data as a PDPTR.

The root cause is:
If we open file w/ readonly flag, disk quota info won't be initialized
for this file, however, following mmap() will force to convert inline
inode via f2fs_convert_inline_inode(), which may increase block usage
for this inode w/o updating quota data, it causes inconsistent disk quota
info.
The issue will happen in following stack:
open(file, O_RDONLY)
mmap(file)
- f2fs_convert_inline_inode
- f2fs_convert_inline_page
- f2fs_reserve_block
- f2fs_reserve_new_block
- f2fs_reserve_new_blocks
- f2fs_i_blocks_write
- dquot_claim_block
inode->i_blocks increase, but the dqb_curspace keep the size for the dquots
is NULL.
To fix this issue, let's call dquot_initialize() anyway in both
f2fs_truncate() and f2fs_convert_inline_inode() functions to avoid potential
inconsistent quota data issue.

In the case of failure while parsing the partitions, the iterator should
be pre decremented by one before starting to free the memory allocated
by kstrdup(). Because in the failure case, kstrdup() will not succeed
and thus no memory will be allocated for the current iteration.
For some reason setting max_register was missed from regmap_config.
Without this cat /sys/kernel/debug/regmap/sdw:0:217:2010:0:1/range
actually throws below Warning.
The correct mask is 0x1f8 (Bit 3-8), but due to missing BIT() 0xf (Bit
0-3) was set instead. This means setting of CPCAP_BIT_MIC1_RX_TIMESLOT0
(Bit 3) still worked (part of both masks). On the other hand the code
does not properly clear the other MIC timeslot bits. I think this
is not a problem, since they are probably initialized to 0 and not
touched by the driver anywhere else. But the mask also contains some
wrong bits, that will be cleared. Bit 0 (CPCAP_BIT_SMB_CDC) should be
safe, since the driver enforces it to be 0 anyways.
Bit 1-2 are CPCAP_BIT_FS_INV and CPCAP_BIT_CLK_INV. This means enabling
audio recording forces the codec into SND_SOC_DAIFMT_NB_NF mode, which
is obviously bad.
The bug probably remained undetected, because there are not many use
cases for routing microphone to the CPU on platforms using cpcap and
user base is small. I do remember having some issues with bad sound
quality when testing voice recording back when I wrote the driver.
It probably was this bug.

While reworking the resources management and departing from using

Since commit 0758cd830494 ("asm-generic/tlb: avoid potential double
flush"), TLB invalidation is elided in tlb_finish_mmu() if no entries
were batched via the tlb_remove_*() functions. Consequently, the
page-table modifications performed by clear_refs_write() in response to
a write to /proc/<pid>/clear_refs do not perform TLB invalidation.
Although this is fine when simply aging the ptes, in the case of
clearing the "soft-dirty" state we can end up with entries where
pte_write() is false, yet a writable mapping remains in the TLB.
Fix this by avoiding the mmu_gather API altogether: managing both the
'tlb_flush_pending' flag on the 'mm_struct' and explicit TLB
invalidation for the sort-dirty path, much like mprotect() does already.

Although it's neat to avoid the suffix for the typical case of a
single PMU, it means systems with multiple CMN instances end up with

Avoid any surprises by not trying to be clever and simply numbering
every instance, even when it might technically prove redundant.
