commit 696450c05181559a35d4d5bee55c465b1ac6fe2e upstream
Clear the RGMII_LINK bit upon detecting link down to be consistent with
setting the bit upon link up. We also move the clearing of the
out-of-band disable to the runtime initialization rather than for each
link up/down transition.

commit 07a57a338adb6ec9e766d6a6790f76527f45ceb5 upstream.
Tony reported that the Machine check recovery was broken in v6.9-rc1, as
he was hitting a VM_BUG_ON when injecting uncorrectable memory errors to
DRAM.
After some more digging and debugging on his side, he realized that this
went back to v6.1, with the introduction of 'commit 0d206b5d2e0d
("mm/swap: add swp_offset_pfn() to fetch PFN from swap entry")'. That
commit, among other things, introduced swp_offset_pfn(), replacing
hwpoison_entry_to_pfn() in its favour.
The patch also introduced a VM_BUG_ON() check for is_pfn_swap_entry(), but
is_pfn_swap_entry() never got updated to cover hwpoison entries, which
means that we would hit the VM_BUG_ON whenever we would call
swp_offset_pfn() for such entries on environments with CONFIG_DEBUG_VM
set. Fix this by updating the check to cover hwpoison entries as well,
and update the comment while we are it.

commit 1db7959aacd905e6487d0478ac01d89f86eb1e51 upstream.
[BUG]
There is a recent report that when memory pressure is high (including
cached pages), btrfs can spend most of its time on memory allocation in
btrfs_alloc_page_array() for compressed read/write.
[CAUSE]
For btrfs_alloc_page_array() we always go alloc_pages_bulk_array(), and
even if the bulk allocation failed (fell back to single page
allocation) we still retry but with extra memalloc_retry_wait().
If the bulk alloc only returned one page a time, we would spend a lot of
time on the retry wait.
The behavior was introduced in commit 395cb57e8560 ("btrfs: wait between
incomplete batch memory allocations").
[FIX]
Although the commit mentioned that other filesystems do the wait, it's
not the case at least nowadays.
All the mainlined filesystems only call memalloc_retry_wait() if they
failed to allocate any page (not only for bulk allocation).
If there is any progress, they won't call memalloc_retry_wait() at all.
For example, xfs_buf_alloc_pages() would only call memalloc_retry_wait()
if there is no allocation progress at all, and the call is not for
metadata readahead.
So I don't believe we should call memalloc_retry_wait() unconditionally
for short allocation.
Call memalloc_retry_wait() if it fails to allocate any page for tree
block allocation (which goes with __GFP_NOFAIL and may not need the
special handling anyway), and reduce the latency for
btrfs_alloc_page_array().

commit 6827738dc684a87ad54ebba3ae7f3d7c977698eb upstream.
After the patch to restrict the use of mmap() to CAP_SYS_RAWIO for
the currently existing devices, most applications can no longer make
use of the accelerators as in production "you don't run things as root".
To keep the DSA and IAA accelerators usable, hook up a write() method
so that applications can still submit work. In the write method,
sufficient input validation is performed to avoid the security issue
that required the mmap CAP_SYS_RAWIO check.
One complication is that the DSA device allows for indirect ("batched")
descriptors. There is no reasonable way to do the input validation
on these indirect descriptors so the write() method will not allow these
to be submitted to the hardware on affected hardware, and the sysfs
enumeration of support for the opcode is also removed.
Early performance data shows that the performance delta for most common
cases is within the noise.

commit e11452eb071b2a8e6ba52892b2e270bbdaa6640d upstream.
On Sapphire Rapids and related platforms, the DSA and IAA devices have an
erratum that causes direct access (for example, by using the ENQCMD or
MOVDIR64 instructions) from untrusted applications to be a security problem.
To solve this, add a flag to the PCI device enumeration and device structures
to indicate the presence/absence of this security exposure. In the mmap()
method of the device, this flag is then used to enforce that the user
has the CAP_SYS_RAWIO capability.
In a future patch, a write() based method will be added that allows untrusted
applications submit work to the accelerator, where the kernel can do
sanity checking on the user input to ensure secure operation of the accelerator.

commit a112d3c72a227f2edbb6d8094472cc6e503e52af upstream.
The NVM configuration files used by WCN3988 and WCN3990/1/8 have two
sets of configuration tags that are enclosed by a type-length header of
type four which the current parser fails to account for.
Instead the driver happily parses random data as if it were valid tags,
something which can lead to the configuration data being corrupted if it
ever encounters the words 0x0011 or 0x001b.
As is clear from commit b63882549b2b ("Bluetooth: btqca: Fix the NVM
baudrate tag offcet for wcn3991") the intention has always been to
process the configuration data also for WCN3991 and WCN3998 which
encodes the baud rate at a different offset.
Fix the parser so that it can handle the WCN3xxx configuration files,
which has an enclosing type-length header of type four and two sets of
TLV tags enclosed by a type-length header of type two and three,
respectively.
Note that only the first set, which contains the tags the driver is
currently looking for, will be parsed for now.
With the parser fixed, the software in-band sleep bit will now be set
for WCN3991 and WCN3998 (as it is for later controllers) and the default
baud rate 3200000 may be updated by the driver also for WCN3xxx
controllers.
Notably the deep-sleep feature bit is already set by default in all
configuration files in linux-firmware.

net_alloc_generic is called by net_alloc, which is called without any
locking. It reads max_gen_ptrs, which is changed under pernet_ops_rwsem. It
is read twice, first to allocate an array, then to set s.len, which is
later used to limit the bounds of the array access.
It is possible that the array is allocated and another thread is
registering a new pernet ops, increments max_gen_ptrs, which is then used
to set s.len with a larger than allocated length for the variable array.
Fix it by reading max_gen_ptrs only once in net_alloc_generic. If
max_gen_ptrs is later incremented, it will be caught in net_assign_generic.

an unused 4K area of the register BAR space into which you can
remap registers. We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM. However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.

commit d18ca8635db2f88c17acbdf6412f26d4f6aff414 upstream.
When using davinci-mcasp as CPU DAI with simple-card, there are some
conditions that cause simple-card to finish registering a sound card before
davinci-mcasp finishes registering all sound components. This creates a
non-working sound card from userspace with no problem indication apart
from not being able to play/record audio on a PCM stream. The issue
arises during simultaneous probe execution of both drivers. Specifically,
the simple-card driver, awaiting a CPU DAI, proceeds as soon as
davinci-mcasp registers its DAI. However, this process can lead to the
client mutex lock (client_mutex in soc-core.c) being held or davinci-mcasp
being preempted before PCM DMA registration on davinci-mcasp finishes.
This situation occurs when the probes of both drivers run concurrently.
Below is the code path for this condition. To solve the issue, defer
davinci-mcasp CPU DAI registration to the last step in the audio part of
it. This way, simple-card CPU DAI parsing will be deferred until all
audio components are registered.
Fail Code Path:
simple-card.c: probe starts
simple-card.c: simple_dai_link_of: simple_parse_node(..,cpu,..) returns EPROBE_DEFER, no CPU DAI yet
davinci-mcasp.c: probe starts
davinci-mcasp.c: devm_snd_soc_register_component() register CPU DAI
simple-card.c: probes again, finish CPU DAI parsing and call devm_snd_soc_register_card()
simple-card.c: finish probe
davinci-mcasp.c: *dma_pcm_platform_register() register PCM DMA
davinci-mcasp.c: probe finish

commit 57a1592784d622ecee0b71940c65429173996b33 upstream.
There are 2 issues with interrupt handling in the mxc4005 driver:
1. mxc4005_set_trigger_state() writes MXC4005_REG_INT_MASK1_BIT_DRDYE
(0x01) to INT_MASK1 to enable the interrupt, but to disable the interrupt
it writes ~MXC4005_REG_INT_MASK1_BIT_DRDYE which is 0xfe, so it enables
all other interrupt sources in the INT_SRC1 register. On the MXC4005 this
is not an issue because only bit 0 of the register is used. On the MXC6655
OTOH this is a problem since bit7 is used as TC (Temperature Compensation)
disable bit and writing 1 to this disables Temperature Compensation which
should only be done when running self-tests on the chip.
Write 0 instead of ~MXC4005_REG_INT_MASK1_BIT_DRDYE to disable
the interrupts to fix this.
2. The datasheets for the MXC4005 / MXC6655 do not state what the reset
value for the INT_MASK0 and INT_MASK1 registers is and since these are
write only we also cannot learn this from the hw. Presumably the reset
value for both is all 0, which means all interrupts disabled.
Explicitly set both registers to 0 from mxc4005_chip_init() to ensure
both masks are actually set to 0.

commit 6d735722063a945de56472bdc6bfcb170fd43b86 upstream.
GUSB3PIPECTL.SUSPENDENABLE and GUSB2PHYCFG.SUSPHY should be cleared
during initialization. Suspend during initialization can result in
undefined behavior due to clock synchronization failure, which often
seen as core soft reset timeout.
The programming guide recommended these bits to be cleared during
initialization for DWC_usb3.0 version 1.94 and above (along with
DWC_usb31 and DWC_usb32). The current check in the driver does not
account if it's set by default setting from coreConsultant.
This is especially the case for DRD when switching mode to ensure the
phy clocks are available to change mode. Depending on the
platforms/design, some may be affected more than others. This is noted
in the DWC_usb3x programming guide under the above registers.
Let's just disable them during driver load and mode switching. Restore
them when the controller initialization completes.
Note that some platforms workaround this issue by disabling phy suspend
through "snps,dis_u3_susphy_quirk" and "snps,dis_u2_susphy_quirk" when
they should not need to.

Testing with KASAN and syzkaller revealed a bug in port.c:disable_store():
usb_hub_to_struct_hub() can return NULL if the hub that the port belongs to
is concurrently removed, but the function does not check for this
possibility before dereferencing the returned value.
It turns out that the first dereference is unnecessary, since hub->intfdev
is the parent of the port device, so it can be changed easily. Adding a
check for hub == NULL prevents further problems.
The same bug exists in the disable_show() routine, and it can be fixed the
same way.

Testing ohci functionality with qemu's pci-ohci emulation often results
in ohci interface stalls, resulting in hung task timeouts.
The problem is caused by lost interrupts between the emulation and the
Linux kernel code. Additional interrupts raised while the ohci interrupt
handler in Linux is running and before the handler clears the interrupt
status are not handled. The fix for a similar problem in ehci suggests
that the problem is likely caused by edge-triggered MSI interrupts. See
commit 0b60557230ad ("usb: ehci: Prevent missed ehci interrupts with
edge-triggered MSI") for details.
Ensure that the ohci interrupt code handles all pending interrupts before
returning to solve the problem.
