manufacturer-specific one.
The macronix part is what is shipped on the boards that come with a

Subject: [PATCH 5.10 045/112] sysctl: Fix data races in proc_douintvec_minmax().

From: Kuniyuki Iwashima <[email protected]>

[ Upstream commit 2d3b559df3ed39258737789aae2ae7973d205bc1 ]

A sysctl variable is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing.

This patch changes proc_douintvec_minmax() to use READ_ONCE() and
WRITE_ONCE() internally to fix data-races on the sysctl side. For now,
proc_douintvec_minmax() itself is tolerant to a data-race, but we still
need to add annotations on the other subsystem's side.

Subject: [PATCH 5.10 008/112] fix race between exit_itimers() and /proc/pid/timers

From: Oleg Nesterov <[email protected]>

commit d5b36a4dbd06c5e8e36ca8ccc552f679069e2946 upstream.

As Chris explains, the comment above exit_itimers() is not correct,
we can race with proc_timers_seq_ops. Change exit_itimers() to clear
signal->posix_timers with ->siglock held.

Subject: [PATCH 5.10 031/112] net/mlx5e: Fix capability check for updating vnic env counters

From: Gal Pressman <[email protected]>

[ Upstream commit 452133dd580811f184e76b1402983182ee425298 ]

The existing capability check for vnic env counters only checks for
receive steering discards, although we need the counters update for the
exposed internal queue oob counter as well. This could result in the
latter counter not being updated correctly when the receive steering
discards counter is not supported.
Fix that by checking whether any counter is supported instead of only
the steering counter capability.

Subject: [PATCH 5.10 014/112] ARM: 9214/1: alignment: advance IT state after emulating Thumb instruction

From: Ard Biesheuvel <[email protected]>

commit e5c46fde75e43c15a29b40e5fc5641727f97ae47 upstream.

After emulating a misaligned load or store issued in Thumb mode, we have
to advance the IT state by hand, or it will get out of sync with the
actual instruction stream, which means we'll end up applying the wrong
condition code to subsequent instructions. This might corrupt the
program state rather catastrophically.

So borrow the it_advance() helper from the probing code, and use it on
CPSR if the emulated instruction is Thumb.

From: Geert Uytterhoeven <[email protected]>

commit d684e0a52d36f8939eda30a0f31ee235ee4ee741 upstream.

Recently, nommu iounmap() was converted from a static inline function to a
macro again, basically reverting commit 4580ba4ad2e6b8dd ("sh: Convert
iounmap() macros to inline functions"). With -Werror, this leads to build
failures like:

drivers/iio/adc/xilinx-ams.c: In function `ams_iounmap_ps':
drivers/iio/adc/xilinx-ams.c:1195:14: error: unused variable `ams' [-Werror=unused-variable]
1195 | struct ams *ams = data;
| ^~~

Fix this by replacing the macros for ioremap() and iounmap() by static
inline functions, based on <asm-generic/io.h>.

TP_printk() portion is executed at the time the buffer is read. That is,
it can be seconds, minutes, days, months, even years later. If the proto
is freed, then this dereference will can also lead to a kernel crash.

Instead, save the sysctl_mem array into the ring buffer and have the
TP_printk() reference that instead. This is the proper and safe way to
read pointers in trace events.

From: Martin Povišer <[email protected]>

[ Upstream commit cd10bb89b0d57bca98eb75e0444854a1c129a14e ]

Make sure there is at least 1 ms delay from reset to first command as
is specified in the datasheet. This is a fix similar to commit
307f31452078 ("ASoC: tas2770: Insert post reset delay").

From: Martin Povišer <[email protected]>

[ Upstream commit d1a10f1b48202e2d183cce144c218a211e98d906 ]

Fix setting of FSYNC polarity in case of LEFT_J and DSP_A/B formats.
Do NOT set the SCFG field as was previously done, because that is not
correct and is also in conflict with the "ASI1 Source" control which
sets the same SCFG field!

Also add support for explicit polarity inversion.

Subject: [PATCH 5.10 070/112] seg6: bpf: fix skb checksum in bpf_push_seg6_encap()

From: Andrea Mayer <[email protected]>

[ Upstream commit 4889fbd98deaf243c3baadc54e296d71c6af1eb0 ]

Both helper functions bpf_lwt_seg6_action() and bpf_lwt_push_encap() use
the bpf_push_seg6_encap() to encapsulate the packet in an IPv6 with Segment
Routing Header (SRH) or insert an SRH between the IPv6 header and the
payload.
To achieve this result, such helper functions rely on bpf_push_seg6_encap()
which, in turn, leverages seg6_do_srh_{encap,inline}() to perform the
required operation (i.e. encap/inline).

This patch removes the initialization of the IPv6 header payload length
from bpf_push_seg6_encap(), as it is now handled properly by
seg6_do_srh_{encap,inline}() to prevent corruption of the skb checksum.

The lock held by ext4_convert_inline_data is xattr_sem, but the lock
held by generic_perform_write is i_rwsem. Therefore, the two locks can
be concurrent.

To solve above issue, we add inode_lock() for ext4_convert_inline_data().

Subject: [PATCH 5.10 069/112] seg6: fix skb checksum in SRv6 End.B6 and End.B6.Encaps behaviors

From: Andrea Mayer <[email protected]>

[ Upstream commit f048880fc77058d864aff5c674af7918b30f312a ]

The SRv6 End.B6 and End.B6.Encaps behaviors rely on functions
seg6_do_srh_{encap,inline}() to, respectively: i) encapsulate the
packet within an outer IPv6 header with the specified Segment Routing
Header (SRH); ii) insert the specified SRH directly after the IPv6
header of the packet.

This patch removes the initialization of the IPv6 header payload length
from the input_action_end_b6{_encap}() functions, as it is now handled
properly by seg6_do_srh_{encap,inline}() to avoid corruption of the skb
checksum.

From: Chia-Lin Kao (AceLan) <[email protected]>

it again on resume.

System like Android allow user control power role from UI, it is possible
to implement application base on typec uevent to refresh UI, but found
there is chance that UI show different state from typec attribute file.

In typec_set_pwr_opmode(), when partner support PD, there is no uevent
send to user space which cause the problem.

Fix it by sending uevent notification when change power mode to PD.

From: Vitaly Kuznetsov <[email protected]>

[ Upstream commit 8a414f943f8b5f94bbaafdec863d6f3dbef33f8a ]

'vector' and 'trig_mode' fields of 'struct kvm_lapic_irq' are left

not needed for APIC_DM_REMRD, they're still referenced by

Subject: [PATCH 5.10 105/112] usb: dwc3: gadget: Fix event pending check

From: Thinh Nguyen <[email protected]>

commit 7441b273388b9a59d8387a03ffbbca9d5af6348c upstream.

The DWC3_EVENT_PENDING flag is used to protect against invalid call to
top-half interrupt handler, which can occur when there's a delay in
software detection of the interrupt line deassertion.

However, the clearing of this flag was done prior to unmasking the
interrupt line, creating opportunity where the top-half handler can
come. This breaks the serialization and creates a race between the
top-half and bottom-half handler, resulting in losing synchronization
between the controller and the driver when processing events.

To fix this, make sure the clearing of the DWC3_EVENT_PENDING is done at
the end of the bottom-half handler.

Subject: [PATCH 5.10 068/112] seg6: fix skb checksum evaluation in SRH encapsulation/insertion

From: Andrea Mayer <[email protected]>

[ Upstream commit df8386d13ea280d55beee1b95f61a59234a3798b ]

Support for SRH encapsulation and insertion was introduced with
commit 6c8702c60b88 ("ipv6: sr: add support for SRH encapsulation and
injection with lwtunnels"), through the seg6_do_srh_encap() and
seg6_do_srh_inline() functions, respectively.
The former encapsulates the packet in an outer IPv6 header along with
the SRH, while the latter inserts the SRH between the IPv6 header and
the payload. Then, the headers are initialized/updated according to the
operating mode (i.e., encap/inline).
Finally, the skb checksum is calculated to reflect the changes applied
to the headers.

The IPv6 payload length ('payload_len') is not initialized
within seg6_do_srh_{inline,encap}() but is deferred in seg6_do_srh(), i.e.
the caller of seg6_do_srh_{inline,encap}().
However, this operation invalidates the skb checksum, since the
'payload_len' is updated only after the checksum is evaluated.

To solve this issue, the initialization of the IPv6 payload length is
moved from seg6_do_srh() directly into the seg6_do_srh_{inline,encap}()
functions and before the skb checksum update takes place.

need to try to guess from the socket retcode if this failure is because
the queue is about to be torn down or not.

We are perfectly safe to just fail it, the request will not be cancelled
later on.

commit 39cdb68c64d84e71a4a717000b6e5de208ee60cc upstream.

A memory overlapping copy occurs when deleting a long line. This memory
overlapping copy can cause data corruption when scr_memcpyw is optimized
to memcpy because memcpy does not ensure its behavior if the destination
buffer overlaps with the source buffer. The line buffer is not always
broken, because the memcpy utilizes the hardware acceleration, whose
result is not deterministic.

Fix this problem by using replacing the scr_memcpyw with scr_memmovew.

From: Ilpo Järvinen <[email protected]>

When console is enabled, univ8250_console_setup() calls
serial8250_console_setup() before .dev is set to uart_port. Therefore,
it will not call pm_runtime_get_sync(). Later, when the actual driver
is going to take over univ8250_console_exit() is called. As .dev is
already set, serial8250_console_exit() makes pm_runtime_put_sync() call
with usage count being zero triggering PM usage count warning

To fix the issue, call pm_runtime_get_sync() in

if it has console enabled.

This problem became apparent only recently because 82586a721595 ("PM:

printout. I confirmed this problem also occurs with v5.18 (w/o the
warning printout, obviously).

From: Charles Keepax <[email protected]>

madera_out1_demux_put returns the value of
snd_soc_dapm_mux_update_power, which returns a 1 if a path was found for
the kcontrol. This is obviously different to the expected return a 1 if
the control was updated value. This results in spurious notifications to
user-space. Update the handling to only return a 1 when the value is
changed.

From: Ilpo Järvinen <[email protected]>

commit 5c5f44e36217de5ead789ff25da71c31c2331c96 upstream.

The code lacks clearing of previous DEAT/DEDT values. Thus, changing
values on the fly results in garbage delays tending towards the maximum
value as more and more bits are ORed together. (Leaving RS485 mode
would have cleared the old values though).

Subject: [PATCH 5.10 112/112] x86/pat: Fix x86_has_pat_wp()

From: Juergen Gross <[email protected]>

commit 230ec83d4299b30c51a1c133b4f2a669972cc08a upstream.

x86_has_pat_wp() is using a wrong test, as it relies on the normal
PAT configuration used by the kernel. In case the PAT MSR has been
setup by another entity (e.g. Xen hypervisor) it might return false
even if the PAT configuration is allowing WP mappings. This due to the
fact that when running as Xen PV guest the PAT MSR is setup by the
hypervisor and cannot be changed by the guest. This results in the WP
related entry to be at a different position when running as Xen PV
guest compared to the bare metal or fully virtualized case.

The correct way to test for WP support is:

1. Get the PTE protection bits needed to select WP mode by reading
__cachemode2pte_tbl[_PAGE_CACHE_MODE_WP] (depending on the PAT MSR
setting this might return protection bits for a stronger mode, e.g.
UC-)
2. Translate those bits back into the real cache mode selected by those
PTE bits by reading __pte2cachemode_tbl[__pte2cm_idx(prot)]
3. Test for the cache mode to be _PAGE_CACHE_MODE_WP

Subject: [PATCH 5.10 057/112] drm/i915/gt: Serialize TLB invalidates with GT resets

From: Chris Wilson <[email protected]>

[ Upstream commit a1c5a7bf79c1faa5633b918b5c0666545e84c4d1 ]

Avoid trying to invalidate the TLB in the middle of performing an
engine reset, as this may result in the reset timing out. Currently,
the TLB invalidate is only serialised by its own mutex, forgoing the
uncore lock, but we can take the uncore->lock as well to serialise
the mmio access, thereby serialising with the GDRST.

Tested on a NUC5i7RYB, BIOS RYBDWi35.86A.0380.2019.0517.1530 with
i915 selftest/hangcheck.

The kernel test robot found this inconsistency:

This is because the match is enclosed in the of_match_ptr()
which compiles into NULL when OF is disabled and this
is unnecessary.

Fix it by dropping of_match_ptr() around the match.

From: Ruozhu Li <[email protected]>

[ Upstream commit f7f70f4aa09dc43d7455c060143e86a017c30548 ]

We encountered a problem that the disconnect command hangs.
After analyzing the log and stack, we found that the triggering
process is as follows:
CPU0 CPU1
nvme_rdma_error_recovery_work
nvme_rdma_teardown_io_queues
nvme_do_delete_ctrl nvme_stop_queues
nvme_remove_namespaces
--clear ctrl->namespaces
nvme_start_queues
--no ns in ctrl->namespaces
nvme_ns_remove return(because ctrl is deleting)
blk_freeze_queue
blk_mq_freeze_queue_wait
--wait for ns to unquiesce to clean infligt IO, hang forever

This problem was not found in older kernels because we will flush
err work in nvme_stop_ctrl before nvme_remove_namespaces.It does not
seem to be modified for functional reasons, the patch can be revert
to solve the problem.

[ Upstream commit 84a85d3fef2e75b1fe9fc2af6f5267122555a1ed ]

pdesc could be null but still dereference pdesc->name and it will lead to
a null pointer access. So we move a null check before dereference.

Subject: [PATCH 5.10 077/112] virtio_mmio: Add missing PM calls to freeze/restore

From: Stephan Gerhold <[email protected]>

[ Upstream commit ed7ac37fde33ccd84e4bd2b9363c191f925364c7 ]

Most virtio drivers provide freeze/restore callbacks to finish up
device usage before suspend and to reinitialize the virtio device after
resume. However, these callbacks are currently only called when using
virtio_pci. virtio_mmio does not have any PM ops defined.

This causes problems for example after suspend to disk (hibernation),
since the virtio devices might lose their state after the VMM is
restarted. Calling virtio_device_freeze()/restore() ensures that
the virtio devices are re-initialized correctly.

Fix this by implementing the dev_pm_ops for virtio_mmio,
similar to virtio_pci_common.

Subject: [PATCH 5.10 092/112] ASoC: dapm: Initialise kcontrol data for mux/demux controls

From: Charles Keepax <[email protected]>

[ Upstream commit 11d7a12f7f50baa5af9090b131c9b03af59503e7 ]

DAPM keeps a copy of the current value of mux/demux controls,
however this value is only initialised in the case of autodisable
controls. This leads to false notification events when first
modifying a DAPM kcontrol that has a non-zero default.

Autodisable controls are left as they are, since they already
initialise the value, and there would be more work required to
support autodisable muxes where the first option isn't disabled
and/or that isn't the default.

Technically this issue could affect mixer/switch elements as well,
although not on any of the devices I am currently running. There
is also a little more work to do to address the issue there due to
that side supporting stereo controls, so that has not been tackled
in this patch.

Subject: [PATCH 5.10 071/112] sfc: fix kernel panic when creating VF

From: Íñigo Huguet <[email protected]>

[ Upstream commit ada74c5539eba06cf8b47d068f92e0b3963a9a6e ]

When creating VFs a kernel panic can happen when calling to
efx_ef10_try_update_nic_stats_vf.

When releasing a DMA coherent buffer, sometimes, I don't know in what
specific circumstances, it has to unmap memory with vunmap. It is
disallowed to do that in IRQ context or with BH disabled. Otherwise, we
hit this line in vunmap, causing the crash:
BUG_ON(in_interrupt());

This patch reenables BH to release the buffer.

Log messages when the bug is hit:

From: Íñigo Huguet <[email protected]>

[ Upstream commit ebe41da5d47ac0fff877e57bd14c54dccf168827 ]

Set the pointer to NULL at release time to not trying to read it later.

Subject: [PATCH 5.10 016/112] cgroup: Use separate src/dst nodes when preloading css_sets for migration

From: Tejun Heo <[email protected]>

commit 07fd5b6cdf3cc30bfde8fe0f644771688be04447 upstream.

Each cset (css_set) is pinned by its tasks. When we're moving tasks around
across csets for a migration, we need to hold the source and destination
csets to ensure that they don't go away while we're moving tasks about. This
is done by linking cset->mg_preload_node on either the
mgctx->preloaded_src_csets or mgctx->preloaded_dst_csets list. Using the
same cset->mg_preload_node for both the src and dst lists was deemed okay as
a cset can't be both the source and destination at the same time.

Unfortunately, this overloading becomes problematic when multiple tasks are
involved in a migration and some of them are identity noop migrations while
others are actually moving across cgroups. For example, this can happen with
the following sequence on cgroup1:

#1> mkdir -p /sys/fs/cgroup/misc/a/b
#2> echo $$ > /sys/fs/cgroup/misc/a/cgroup.procs
#3> RUN_A_COMMAND_WHICH_CREATES_MULTIPLE_THREADS &
#4> PID=$!
#5> echo $PID > /sys/fs/cgroup/misc/a/b/tasks
#6> echo $PID > /sys/fs/cgroup/misc/a/cgroup.procs

the process including the group leader back into a. In this final migration,
non-leader threads would be doing identity migration while the group leader
is doing an actual one.

After #3, let's say the whole process was in cset A, and that after #4, the
leader moves to cset B. Then, during #6, the following happens:

1. cgroup_migrate_add_src() is called on B for the leader.

2. cgroup_migrate_add_src() is called on A for the other threads.

3. cgroup_migrate_prepare_dst() is called. It scans the src list.

4. It notices that B wants to migrate to A, so it tries to A to the dst
list but realizes that its ->mg_preload_node is already busy.

5. and then it notices A wants to migrate to A as it's an identity
migration, it culls it by list_del_init()'ing its ->mg_preload_node and
putting references accordingly.

6. The rest of migration takes place with B on the src list but nothing on
the dst list.

This means that A isn't held while migration is in progress. If all tasks
leave A before the migration finishes and the incoming task pins it, the
cset will be destroyed leading to use-after-free.

This is caused by overloading cset->mg_preload_node for both src and dst
preload lists. We wanted to exclude the cset from the src list but ended up
inadvertently excluding it from the dst list too.

This patch fixes the issue by separating out cset->mg_preload_node into
->mg_src_preload_node and ->mg_dst_preload_node, so that the src and dst
preloadings don't interfere with each other.

Subject: [PATCH 5.10 020/112] fs/remap: constrain dedupe of EOF blocks

From: Dave Chinner <[email protected]>

commit 5750676b64a561f7ec920d7c6ba130fc9c7378f3 upstream.

If dedupe of an EOF block is not constrainted to match against only
other EOF blocks with the same EOF offset into the block, it can
match against any other block that has the same matching initial
bytes in it, even if the bytes beyond EOF in the source file do
not match.

Fix this by constraining the EOF block matching to only match
against other EOF blocks that have identical EOF offsets and data.
This allows "whole file dedupe" to continue to work without allowing
eof blocks to randomly match against partial full blocks with the
same data.

Subject: [PATCH 5.10 102/112] signal handling: dont use BUG_ON() for debugging

From: Linus Torvalds <[email protected]>

[ Upstream commit a382f8fee42ca10c9bfce0d2352d4153f931f5dc ]

These are indeed "should not happen" situations, but it turns out recent
changes made the 'task_is_stopped_or_trace()' case trigger (fix for that
exists, is pending more testing), and the BUG_ON() makes it
unnecessarily hard to actually debug for no good reason.

It's been that way for a long time, but let's make it clear: BUG_ON() is
not good for debugging, and should never be used in situations where you
could just say "this shouldn't happen, but we can continue".

Use WARN_ON_ONCE() instead to make sure it gets logged, and then just
continue running. Instead of making the system basically unusuable
because you crashed the machine while potentially holding some very core
locks (eg this function is commonly called while holding 'tasklist_lock'
for writing).

From: Juergen Gross <[email protected]>

[ Upstream commit 38fa5479b41376dc9d7f57e71c83514285a25ca0 ]

The .brk section has the same properties as .bss: it is an alloc-only
section and should be cleared before being used.

Not doing so is especially a problem for Xen PV guests, as the
hypervisor will validate page tables (check for writable page tables
and hypervisor private bits) before accepting them to be used.

Make sure .brk is initially zero by letting clear_bss() clear the brk
area, too.

From: Xiu Jianfeng <[email protected]>

commit 51dd64bb99e4478fc5280171acd8e1b529eadaf7 upstream.

This reverts commit ccf11dbaa07b328fa469415c362d33459c140a37.

Commit ccf11dbaa07b ("evm: Fix memleak in init_desc") said there is
memleak in init_desc. That may be incorrect, as we can see, tmp_tfm is
saved in one of the two global variables hmac_tfm or evm_tfm[hash_algo],
then if init_desc is called next time, there is no need to alloc tfm
again, so in the error path of kmalloc desc or crypto_shash_init(desc),
It is not a problem without freeing tmp_tfm.

And also that commit did not reset the global variable to NULL after
freeing tmp_tfm and this makes *tfm a dangling pointer which may cause a
UAF issue.

From: Kuniyuki Iwashima <[email protected]>

[ Upstream commit c31bcc8fb89fc2812663900589c6325ba35d9a65 ]

A sysctl variable is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing.

This patch changes proc_doulongvec_minmax() to use READ_ONCE() and
WRITE_ONCE() internally to fix data-races on the sysctl side. For now,
proc_doulongvec_minmax() itself is tolerant to a data-race, but we still
need to add annotations on the other subsystem's side.

to 'host'. Thus, when a source address is selected, 127.0.0.1 may be chosen
but rejected when the route is used.

When using a route without a nexthop id, the scope can be configured in the
route, thus the problem doesn't exist.

To explain more deeply: when a user creates a nexthop, it cannot specify
the scope. To create it, the function nh_create_ipv4() calls fib_check_nh()
with scope set to 0. fib_check_nh() calls fib_check_nh_nongw() wich was
setting scope to 'host'. Then, nh_create_ipv4() calls
fib_info_update_nhc_saddr() with scope set to 'host'. The src addr is
chosen before the route is inserted.

When a 'standard' route (ie without a reference to a nexthop) is added,
fib_create_info() calls fib_info_update_nhc_saddr() with the scope set by
the user. iproute2 set the scope to 'link' by default.

Here is a way to reproduce the problem:
ip netns add foo
ip -n foo link set lo up
ip netns add bar
ip -n bar link set lo up
sleep 1

ip -n foo link add name eth0 type dummy
ip -n foo link set eth0 up
ip -n foo address add 192.168.0.1/24 dev eth0

ip -n foo link add name veth0 type veth peer name veth1 netns bar
ip -n foo link set veth0 up
ip -n bar link set veth1 up

ip -n bar address add 192.168.1.1/32 dev veth1
ip -n bar route add default dev veth1

ip -n foo nexthop add id 1 dev veth0
ip -n foo route add 192.168.1.1 nhid 1

Try to get/use the route:
> $ ip -n foo route get 192.168.1.1
> RTNETLINK answers: Invalid argument
> $ ip netns exec foo ping -c1 192.168.1.1
> ping: connect: Invalid argument

Try without nexthop group (iproute2 sets scope to 'link' by dflt):
ip -n foo route del 192.168.1.1
ip -n foo route add 192.168.1.1 dev veth0

Try to get/use the route:
> $ ip -n foo route get 192.168.1.1
> 192.168.1.1 dev veth0 src 192.168.0.1 uid 0
> cache

From: Stephan Gerhold <[email protected]>

[ Upstream commit e0c2ce8217955537dd5434baeba061f209797119 ]

Virtio devices might lose their state when the VMM is restarted
after a suspend to disk (hibernation) cycle. This means that the
guest page size register must be restored for the virtio_mmio legacy
interface, since otherwise the virtio queues are not functional.

This is particularly problematic for QEMU that currently still defaults
to using the legacy interface for virtio_mmio. Write the guest page
size register again in virtio_mmio_restore() to make legacy virtio_mmio
devices work correctly after hibernation.

commit 94e8100678889ab428e68acadf042de723f094b9 upstream.

xenvif_rx_next_skb() is expecting the rx queue not being empty, but
in case the loop in xenvif_rx_action() is doing multiple iterations,
the availability of another skb in the rx queue is not being checked.

This can lead to crashes:

Subject: [PATCH 5.10 017/112] btrfs: return -EAGAIN for NOWAIT dio reads/writes on compressed and inline extents

From: Filipe Manana <[email protected]>

commit a4527e1853f8ff6e0b7c2dadad6268bd38427a31 upstream.

When doing a direct IO read or write, we always return -ENOTBLK when we
find a compressed extent (or an inline extent) so that we fallback to
buffered IO. This however is not ideal in case we are in a NOWAIT context
(io_uring for example), because buffered IO can block and we currently
have no support for NOWAIT semantics for buffered IO, so if we need to
fallback to buffered IO we should first signal the caller that we may
need to block by returning -EAGAIN instead.

This behaviour can also result in short reads being returned to user
space, which although it's not incorrect and user space should be able
to deal with partial reads, it's somewhat surprising and even some popular
applications like QEMU (Link tag #1) and MariaDB (Link tag #2) don't
deal with short reads properly (or at all).

The short read case happens when we try to read from a range that has a
non-compressed and non-inline extent followed by a compressed extent.
After having read the first extent, when we find the compressed extent we
return -ENOTBLK from btrfs_dio_iomap_begin(), which results in iomap to
treat the request as a short read, returning 0 (success) and waiting for
previously submitted bios to complete (this happens at
fs/iomap/direct-io.c:__iomap_dio_rw()). After that, and while at
btrfs_file_read_iter(), we call filemap_read() to use buffered IO to
read the remaining data, and pass it the number of bytes we were able to
read with direct IO. Than at filemap_read() if we get a page fault error
when accessing the read buffer, we return a partial read instead of an
-EFAULT error, because the number of bytes previously read is greater
than zero.

So fix this by returning -EAGAIN for NOWAIT direct IO when we find a
compressed or an inline extent.

Subject: [PATCH 5.10 079/112] netfilter: br_netfilter: do not skip all hooks with 0 priority

From: Florian Westphal <[email protected]>

[ Upstream commit c2577862eeb0be94f151f2f1fff662b028061b00 ]

When br_netfilter module is loaded, skbs may be diverted to the
ipv4/ipv6 hooks, just like as if we were routing.

Unfortunately, bridge filter hooks with priority 0 may be skipped
in this case.

Example:
1. an nftables bridge ruleset is loaded, with a prerouting
hook that has priority 0.
2. interface is added to the bridge.
3. no tcp packet is ever seen by the bridge prerouting hook.
4. flush the ruleset
5. load the bridge ruleset again.
6. tcp packets are processed as expected.

After 1) the only registered hook is the bridge prerouting hook, but its
not called yet because the bridge hasn't been brought up yet.

After 2), hook order is:
0 br_nf_pre_routing // br_netfilter internal hook
0 chain bridge f prerouting // nftables bridge ruleset

The packet is diverted to br_nf_pre_routing.
If call-iptables is off, the nftables bridge ruleset is called as expected.

But if its enabled, br_nf_hook_thresh() will skip it because it assumes
that all 0-priority hooks had been called previously in bridge context.

To avoid this, check for the br_nf_pre_routing hook itself, we need to
resume directly after it, even if this hook has a priority of 0.

Unfortunately, this still results in different packet flow.
With this fix, the eval order after in 3) is:
1. br_nf_pre_routing
2. ip(6)tables (if enabled)
3. nftables bridge

but after 5 its the much saner:
1. nftables bridge
2. br_nf_pre_routing
3. ip(6)tables (if enabled)

Unfortunately I don't see a solution here:
It would be possible to move br_nf_pre_routing to a higher priority
so that it will be called later in the pipeline, but this also impacts
ebtables evaluation order, and would still result in this very ordering
problem for all nftables-bridge hooks with the same priority as the
br_nf_pre_routing one.

Searching back through the git history I don't think this has
ever behaved in any other way, hence, no fixes-tag.

Subject: [PATCH 5.10 058/112] sysctl: Fix data-races in proc_dointvec_ms_jiffies().

From: Kuniyuki Iwashima <[email protected]>

[ Upstream commit 7d1025e559782b58824b36cb8ad547a69f2e4b31 ]

A sysctl variable is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing.

This patch changes proc_dointvec_ms_jiffies() to use READ_ONCE() and
WRITE_ONCE() internally to fix data-races on the sysctl side. For now,
proc_dointvec_ms_jiffies() itself is tolerant to a data-race, but we still
need to add annotations on the other subsystem's side.

Subject: [PATCH 5.10 028/112] ARM: 9210/1: Mark the FDT_FIXED sections as shareable

From: Zhen Lei <[email protected]>

[ Upstream commit 598f0a99fa8a35be44b27106b43ddc66417af3b1 ]

commit 7a1be318f579 ("ARM: 9012/1: move device tree mapping out of linear
region") use FDT_FIXED_BASE to map the whole FDT_FIXED_SIZE memory area
which contains fdt. But it only reserves the exact physical memory that
fdt occupied. Unfortunately, this mapping is non-shareable. An illegal or
speculative read access can bring the RAM content from non-fdt zone into
cache, PIPT makes it to be hit by subsequently read access through
shareable mapping(such as linear mapping), and the cache consistency
between cores is lost due to non-shareable property.

|<---------FDT_FIXED_SIZE------>|
| |
-------------------------------
| <non-fdt> | <fdt> | <non-fdt> |
-------------------------------

1. CoreA read <non-fdt> through MT_ROM mapping, the old data is loaded
into the cache.
2. CoreB write <non-fdt> to update data through linear mapping. CoreA
received the notification to invalid the corresponding cachelines, but
the property non-shareable makes it to be ignored.
3. CoreA read <non-fdt> through linear mapping, cache hit, the old data
is read.

To eliminate this risk, add a new memory type MT_MEMORY_RO. Compared to
MT_ROM, it is shareable and non-executable.

Here's an example:
list_del corruption. prev->next should be c0ecbf74, but was c08410dc
kernel BUG at lib/list_debug.c:53!

(rcu_gp_kthread) from (kthread+0x14c/0x15c)
(kthread) from (ret_from_fork+0x14/0x24)

The faulty list node to be deleted is a local variable, its address is
c0ecbf74. The dumped stack shows that 'prev' = c0ecbf74, but its value
before lib/list_debug.c:53 is c08410dc. A large amount of printing results
in swapping out the cacheline containing the old data(MT_ROM mapping is
read only, so the cacheline cannot be dirty), and the subsequent dump
operation obtains new data from the DDR.

[ Upstream commit 0a18d802d65cf662644fd1d369c86d84a5630652 ]

sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When
devm_add_action() fails, sfp is not freed, which leads to a memory leak.

We should use devm_add_action_or_reset() instead of devm_add_action().

Subject: [PATCH 5.10 009/112] mm: split huge PUD on wp_huge_pud fallback

From: Gowans, James <[email protected]>

commit 14c99d65941538aa33edd8dc7b1bbbb593c324a2 upstream.

Currently the implementation will split the PUD when a fallback is taken
inside the create_huge_pud function. This isn't where it should be done:
the splitting should be done in wp_huge_pud, just like it's done for PMDs.
Reason being that if a callback is taken during create, there is no PUD
yet so nothing to split, whereas if a fallback is taken when encountering
a write protection fault there is something to split.

It looks like this was the original intention with the commit where the
splitting was introduced, but somehow it got moved to the wrong place
between v1 and v2 of the patch series. Rebase mistake perhaps.

Subject: [PATCH 5.10 026/112] spi: amd: Limit max transfer and message size

From: Cristian Ciocaltea <[email protected]>

[ Upstream commit 6ece49c56965544262523dae4a071ace3db63507 ]

Enabling the SPI CS35L41 audio codec driver for Steam Deck [1]
revealed a problem with the current AMD SPI controller driver
implementation, consisting of an unrecoverable system hang.

The issue can be prevented if we ensure the max transfer size
and the max message size do not exceed the FIFO buffer size.

According to the implementation of the downstream driver, the
AMD SPI controller is not able to handle more than 70 bytes per
transfer, which corresponds to the size of the FIFO buffer.

Hence, let's fix this by setting the SPI limits mentioned above.

Subject: [PATCH 5.10 021/112] nilfs2: fix incorrect masking of permission flags for symlinks

From: Ryusuke Konishi <[email protected]>

commit 5924e6ec1585445f251ea92713eb15beb732622a upstream.

The permission flags of newly created symlinks are wrongly dropped on
nilfs2 with the current umask value even though symlinks should have 777
(rwxrwxrwx) permissions:

$ umask
0022
$ touch file && ln -s file symlink; ls -l file symlink
-rw-r--r--. 1 root root 0 Jun 23 16:29 file
lrwxr-xr-x. 1 root root 4 Jun 23 16:29 symlink -> file

This fixes the bug by inserting a missing check that excludes
symlinks.

DVC value 0xc8 is -100dB and 0xc9 is mute; this needs to map to
-100.5dB as far as the dB scale is concerned. Fix that and enable

From: Kuniyuki Iwashima <[email protected]>

[ Upstream commit 4762b532ec9539755aab61445d5da6e1926ccb99 ]

A sysctl variable is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing.

This patch changes proc_douintvec() to use READ_ONCE() and WRITE_ONCE()
internally to fix data-races on the sysctl side. For now, proc_douintvec()
itself is tolerant to a data-race, but we still need to add annotations on
the other subsystem's side.

From: Jon Hunter <[email protected]>

[ Upstream commit 029c1c2059e9c4b38f97a06204cdecd10cfbeb8a ]

There is a long-standing issue with the Synopsys DWC Ethernet driver
for Tegra194 where random system crashes have been observed [0]. The
problem occurs when the split header feature is enabled in the stmmac
driver. In the bad case, a larger than expected buffer length is
received and causes the calculation of the total buffer length to
overflow. This results in a very large buffer length that causes the
kernel to crash. Why this larger buffer length is received is not clear,
however, the feedback from the NVIDIA design team is that the split
header feature is not supported for Tegra194. Therefore, disable split
header support for Tegra194 to prevent these random crashes from
occurring.

From: Stafford Horne <[email protected]>

[ Upstream commit 8520501346ed8d1c4a6dfa751cb57328a9c843f1 ]

The mask_ack operation clears the interrupt by writing to the PICSR
register. This we don't want for level triggered interrupt because
it does not actually clear the interrupt on the source hardware.

This was causing issues in qemu with multi core setups where
interrupts would continue to fire even though they had been cleared in
PICSR.

Just remove the mask_ack operation.

Subject: [PATCH 5.10 027/112] ARM: 9209/1: Spectre-BHB: avoid pr_info() every time a CPU comes out of idle

From: Ard Biesheuvel <[email protected]>

[ Upstream commit 0609e200246bfd3b7516091c491bec4308349055 ]

Jon reports that the Spectre-BHB init code is filling up the kernel log
with spurious notifications about which mitigation has been enabled,
every time any CPU comes out of a low power state.

Given that Spectre-BHB mitigations are system wide, only a single
mitigation can be enabled, and we already print an error if two types of
CPUs coexist in a single system that require different Spectre-BHB
mitigations.

This means that the pr_info() that describes the selected mitigation
does not need to be emitted for each CPU anyway, and so we can simply
emit it only once.

In order to clarify the above in the log message, update it to describe
that the selected mitigation will be enabled on all CPUs, including ones
that are unaffected. If another CPU comes up later that is affected and
requires a different mitigation, we report an error as before.

From: Dmitry Osipenko <[email protected]>

commit 9fc33eaaa979d112d10fea729edcd2a2e21aa912 upstream.

Calling madvise IOCTL twice on BO causes memory shrinker list corruption
and crashes kernel because BO is already on the list and it's added to
the list again, while BO should be removed from the list before it's
re-added. Fix it.

From: Kuniyuki Iwashima <[email protected]>

[ Upstream commit e877820877663fbae8cb9582ea597a7230b94df3 ]

A sysctl variable is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing.

This patch changes proc_dointvec_jiffies() to use READ_ONCE() and
WRITE_ONCE() internally to fix data-races on the sysctl side. For now,
proc_dointvec_jiffies() itself is tolerant to a data-race, but we still
need to add annotations on the other subsystem's side.
