r8169: fix deadlock on RTL8125 in jumbo mtu mode
[ Upstream commit 59d395ed606d8df14615712b0cdcdadb2d962175 ]
The original change results in a deadlock if jumbo mtu mode is used.
Reason is that the phydev lock is held when rtl_reset_work() is called
here, and rtl_jumbo_config() calls phy_start_aneg() which also tries
to acquire the phydev lock. Fix this by calling rtl_reset_work()
asynchronously.

mmc: cqhci: Fix task clearing in CQE error recovery
[ Upstream commit 1de1b77982e1a1df9707cb11f9b1789e6b8919d4 ]
If a task completion notification (TCN) is received when there is no
outstanding task, the cqhci driver issues a "spurious TCN" warning. This
was observed to happen right after CQE error recovery.
When an error interrupt is received the driver runs recovery logic.
It halts the controller, clears all pending tasks, and then re-enables
it. On some platforms, like Intel Jasper Lake, a stale task completion
event was observed, regardless of the CQHCI_CLEAR_ALL_TASKS bit being set.
This results in either:
a) Spurious TC completion event for an empty slot.
b) Corrupted data being passed up the stack, as a result of premature
completion for a newly added task.
Rather than add a quirk for affected controllers, ensure tasks are cleared
by toggling CQHCI_ENABLE, which would happen anyway if
cqhci_clear_all_tasks() timed out. This is simpler and should be safe and
effective for all controllers.

cpufreq: imx6q: Don't disable 792 Mhz OPP unnecessarily
[ Upstream commit 2e4e0984c7d696cc74cf2fd7e7f62997f0e9ebe6 ]
For a 900MHz i.MX6ULL CPU the 792MHz OPP is disabled. There is no
convincing reason to disable this OPP. If a CPU can run at 900MHz,
it should also be able to cope with 792MHz. Looking at the voltage
level of 792MHz in [1] (page 24, table 10. "Operating Ranges") the
current defined OPP is above the minimum. So the voltage level
shouldn't be a problem. However in [2] (page 24, table 10.
"Operating Ranges"), it is not mentioned that 792MHz OPP isn't
allowed. Change it to only disable 792MHz OPP for i.MX6ULL types
below 792 MHz.

scsi: core: Introduce the scsi_cmd_to_rq() function
[ Upstream commit 51f3a478892873337c54068d1185bcd797000a52 ]
The 'request' member of struct scsi_cmnd is superfluous. The struct request
and struct scsi_cmnd data structures are adjacent and hence the request
pointer can be derived easily from a scsi_cmnd pointer. Introduce a helper
function that performs that conversion in a type-safe way. This patch is
the first step towards removing the request member from struct
scsi_cmnd. Making that change has the following advantages:
- This is a performance optimization since adding an offset to a pointer
takes less time than dereferencing a pointer.
- struct scsi_cmnd becomes smaller.

fs: add ctime accessors infrastructure
[ Upstream commit 9b6304c1d53745c300b86f202d0dcff395e2d2db ]
struct timespec64 has unused bits in the tv_nsec field that can be used
for other purposes. In future patches, we're going to change how the
inode->i_ctime is accessed in certain inodes in order to make use of
them. In order to do that safely though, we'll need to eradicate raw
accesses of the inode->i_ctime field from the kernel.
Add new accessor functions for the ctime that we use to replace them.

drm/amdgpu: don't use ATRM for external devices

The ATRM ACPI method is for fetching the dGPU vbios rom
image on laptops and all-in-one systems. It should not be
used for external add in cards. If the dGPU is thunderbolt
connected, don't try ATRM.
v2: pci_is_thunderbolt_attached only works for Intel. Use
pdev->external_facing instead.

driver core: Move the "removable" attribute from USB to core
[ Upstream commit 70f400d4d957c2453c8689552ff212bc59f88938 ]
Move the "removable" attribute from USB to core in order to allow it to be
supported by other subsystem / buses. Individual buses that want to support
this attribute can populate the removable property of the device while
enumerating it with the 3 possible values -
- "unknown"
- "fixed"
- "removable"
Leaving the field unchanged (i.e. "not supported") would mean that the
attribute would not show up in sysfs for that device. The UAPI (location,
symantics etc) for the attribute remains unchanged.
Move the "removable" attribute from USB to the device core so it can be
used by other subsystems / buses.
By default, devices do not have a "removable" attribute in sysfs.
If a subsystem or bus driver wants to support a "removable" attribute, it
should call device_set_removable() before calling device_register() or
device_add(), e.g.:
device_set_removable(dev, DEVICE_REMOVABLE);
device_register(dev);
The possible values and the resulting sysfs attribute contents are:
DEVICE_REMOVABLE_UNKNOWN -> "unknown"
DEVICE_REMOVABLE -> "removable"
DEVICE_FIXED -> "fixed"
Convert the USB "removable" attribute to use this new device core
functionality. There should be no user-visible change in the location or
semantics of attribute for USB devices.

s390/cmma: fix detection of DAT pages
[ Upstream commit 44d93045247661acbd50b1629e62f415f2747577 ]
If the cmma no-dat feature is available the kernel page tables are walked
to identify and mark all pages which are used for address translation (all
region, segment, and page tables). In a subsequent loop all other pages are
marked as "no-dat" pages with the ESSA instruction.
This information is visible to the hypervisor, so that the hypervisor can
optimize purging of guest TLB entries. The initial loop however is
incorrect: only the first three of the four pages which belong to segment
and region tables will be marked as being used for DAT. The last page is
incorrectly marked as no-dat.
This can result in incorrect guest TLB flushes.
Fix this by simply marking all four pages.

Note that ApolloLake Chromebooks officially ship with the Skylake

'options intel-dspcfg dsp_driver=3'. There is no plan to change the
default selection.

For additional flexibility, this patch adds the 'tplg_filename' module
parameter to override topology names.
To avoid any confusion between DMI- and parameter-override, a variable
rename is added.

There are already 3 versions of the Up boards with support for the SOF

continue to add quirks for each version, let's add a wildcard.
For WHL and TGL, the authentication supports both the SOF community
key and the firmware signed with the Intel production key. Given two
choices, the community key is the preferred option to allow developers
to sign their own firmware. The firmware signed with production key
can still be selected if needed with a kernel module
option (snd-sof-pci.fw_path="intel/sof")

Fix races between ravb_tx_timeout_work() and functions of net_device_ops

...
__dev_close_many()
// Under rtnl lock
ravb_close()
cancel_work_sync()
// Waiting
ravb_tx_timeout_work()
rtnl_lock()
// This is possible to cause a deadlock

r8169: prevent potential deadlock in rtl8169_close
[ Upstream commit 91d3d149978ba7b238198dd80e4b823756aa7cfa ]
ndo_stop() is RTNL-protected by net core, and the worker function takes
RTNL as well. Therefore we will deadlock when trying to execute a
pending work synchronously. To fix this execute any pending work
asynchronously. This will do no harm because netif_running() is false
in ndo_stop(), and therefore the work function is effectively a no-op.
However we have to ensure that no task is running or pending after
rtl_remove_one(), therefore add a call to cancel_work_sync().

When more than 64 VFs are enabled for a PF then mbox communication
between VF and PF is not working as mbox work queueing for few VFs
are skipped due to wrong calculation of VF numbers.

selftests/net: mptcp: fix uninitialized variable warnings

Same init_rng() in both tests. The function reads /dev/urandom to
initialize srand(). In case of failure, it falls back onto the
entropy in the uninitialized variable. Not sure if this is on purpose.
But failure reading urandom should be rare, so just fail hard. While
at it, convert to getrandom(). Which man 4 random suggests is simpler
and more robust.

dpaa2-eth: increase the needed headroom to account for alignment
[ Upstream commit f422abe3f23d483cf01f386819f26fb3fe0dbb2b ]
Increase the needed headroom to account for a 64 byte alignment
restriction which, with this patch, we make mandatory on the Tx path.
The case in which the amount of headroom needed is not available is
already handled by the driver which instead sends a S/G frame with the
first buffer only holding the SW and HW annotation areas.
Without this patch, we can empirically see data corruption happening
between Tx and Tx confirmation which sometimes leads to the SW
annotation area being overwritten.
Since this is an old IP where the hardware team cannot help to
understand the underlying behavior, we make the Tx alignment mandatory
for all frames to avoid the crash on Tx conf. Also, remove the comment
that suggested that this is just an optimization.
This patch also sets the needed_headroom net device field to the usual
value that the driver would need on the Tx path:
- 64 bytes for the software annotation area
- 64 bytes to account for a 64 byte aligned buffer address

usb: config: fix iteration issue in 'usb_get_bos_descriptor()'
[ Upstream commit 974bba5c118f4c2baf00de0356e3e4f7928b4cbc ]
The BOS descriptor defines a root descriptor and is the base descriptor for
accessing a family of related descriptors.
Function 'usb_get_bos_descriptor()' encounters an iteration issue when
skipping the 'USB_DT_DEVICE_CAPABILITY' descriptor type. This results in
the same descriptor being read repeatedly.
To address this issue, a 'goto' statement is introduced to ensure that the
pointer and the amount read is updated correctly. This ensures that the
function iterates to the next descriptor instead of reading the same
descriptor repeatedly.

USB: core: Change configuration warnings to notices
[ Upstream commit 7a09c1269702db8eccb6f718da2b00173e1e0034 ]
It has been pointed out that the kernel log messages warning about
problems in USB configuration and related descriptors are vexing for
users. The warning log level has a fairly high priority, but the user
can do nothing to fix the underlying errors in the device's firmware.
To reduce the amount of useless information produced by tools that
filter high-priority log messages, we can change these warnings to
notices, i.e., change dev_warn() to dev_notice(). The same holds for
a few messages that currently use dev_err(): Unless they indicate a
failure that might make a device unusable (such as inability to
transfer a config descriptor), change them to dev_notice() also.

The rtnl lock also needs to be held before rndis_filter_device_add()

VF NIC offering and registering. If VF NIC finished register_netdev()
earlier it may cause name based config failure.
To fix this issue, move the call to rtnl_lock() before
rndis_filter_device_add(), so VF will be registered later than netvsc

btrfs: make error messages more clear when getting a chunk map
commit 7d410d5efe04e42a6cd959bfe6d59d559fdf8b25 upstream.
When getting a chunk map, at btrfs_get_chunk_map(), we do some sanity
checks to verify we found a chunk map and that map found covers the
logical address the caller passed in. However the messages aren't very
clear in the sense that don't mention the issue is with a chunk map and
one of them prints the 'length' argument as if it were the end offset of
the requested range (while the in the string format we use %llu-%llu
which suggests a range, and the second %llu-%llu is actually a range for
the chunk map). So improve these two details in the error messages.

btrfs: send: ensure send_fd is writable
commit 0ac1d13a55eb37d398b63e6ff6db4a09a2c9128c upstream.
kernel_write() requires the caller to ensure that the file is writable.
Let's do that directly after looking up the ->send_fd.
We don't need a separate bailout path because the "out" path already
does fput() if ->send_filp is non-NULL.
This has no security impact for two reasons:
- the ioctl requires CAP_SYS_ADMIN
- __kernel_write() bails out on read-only files - but only since 5.8,
see commit a01ac27be472 ("fs: check FMODE_WRITE in __kernel_write")

btrfs: fix off-by-one when checking chunk map includes logical address
commit 5fba5a571858ce2d787fdaf55814e42725bfa895 upstream.
At btrfs_get_chunk_map() we get the extent map for the chunk that contains
the given logical address stored in the 'logical' argument. Then we do
sanity checks to verify the extent map contains the logical address. One
of these checks verifies if the extent map covers a range with an end
offset behind the target logical address - however this check has an
off-by-one error since it will consider an extent map whose start offset
plus its length matches the target logical address as inclusive, while
the fact is that the last byte it covers is behind the target logical
address (by 1).
So fix this condition by using '<=' rather than '<' when comparing the
extent map's "start + length" against the target logical address.

However, on some of the paths, 're' are not deallocated and may lead to
memory leaks.
For example: lookup_block_entry() for 'be' returns NULL, the out label
will be invoked. During that flow ref and 'ra' are freed but not 're',
which can potentially lead to a memory leak.

btrfs: add dmesg output for first mount and last unmount of a filesystem
commit 2db313205f8b96eea467691917138d646bb50aef upstream.
There is a feature request to add dmesg output when unmounting a btrfs.
There are several alternative methods to do the same thing, but with
their own problems:
- Use eBPF to watch btrfs_put_super()/open_ctree()
Not end user friendly, they have to dip their head into the source
code.
- Watch for directory /sys/fs/<uuid>/
This is way more simple, but still requires some simple device -> uuid
lookups. And a script needs to use inotify to watch /sys/fs/.
Compared to all these, directly outputting the information into dmesg
would be the most simple one, with both device and UUID included.
And since we're here, also add the output when mounting a filesystem for
the first time for parity. A more fine grained monitoring of subvolume
mounts should be done by another layer, like audit.
Now mounting a btrfs with all default mkfs options would look like this:
[81.906566] BTRFS info (device dm-8): first mount of filesystem 633b5c16-afe3-4b79-b195-138fe145e4f2
[81.907494] BTRFS info (device dm-8): using crc32c (crc32c-intel) checksum algorithm
[81.908258] BTRFS info (device dm-8): using free space tree
[81.912644] BTRFS info (device dm-8): auto enabling async discard
[81.913277] BTRFS info (device dm-8): checking UUID tree
[91.668256] BTRFS info (device dm-8): last unmount of filesystem 633b5c16-afe3-4b79-b195-138fe145e4f2

parisc: Drop the HP-UX ENOSYM and EREMOTERELEASE error codes
commit e5f3e299a2b1e9c3ece24a38adfc089aef307e8a upstream.
Those return codes are only defined for the parisc architecture and
are leftovers from when we wanted to be HP-UX compatible.
They are not returned by any Linux kernel syscall but do trigger
problems with the glibc strerrorname_np() and strerror() functions as
reported in glibc issue #31080.
There is no need to keep them, so simply remove them.

powerpc: Don't clobber f0/vs0 during fp|altivec register save
commit 5e1d824f9a283cbf90f25241b66d1f69adb3835b upstream.
During floating point and vector save to thread data f0/vs0 are
clobbered by the FPSCR/VSCR store routine. This has been obvserved to
lead to userspace register corruption and application data corruption
with io-uring.
Fix it by restoring f0/vs0 after FPSCR/VSCR store has completed for
all the FP, altivec, VMX register save paths.
Tested under QEMU in kvm mode, running on a Talos II workstation with
dual POWER9 DD2.2 CPUs.
Additional detail (mpe):
Typically save_fpu() is called from __giveup_fpu() which saves the FP
regs and also *turns off FP* in the tasks MSR, meaning the kernel will
reload the FP regs from the thread struct before letting the task use FP
again. So in that case save_fpu() is free to clobber f0 because the FP
regs no longer hold live values for the task.
There is another case though, which is the path via:
sys_clone()
...
copy_process()
dup_task_struct()
arch_dup_task_struct()
flush_all_to_thread()
save_all()
That path saves the FP regs but leaves them live. That's meant as an
optimisation for a process that's using FP/VSX and then calls fork(),
leaving the regs live means the parent process doesn't have to take a
fault after the fork to get its FP regs back. The optimisation was added
in commit 8792468da5e1 ("powerpc: Add the ability to save FPU without
giving it up").
That path does clobber f0, but f0 is volatile across function calls,
and typically programs reach copy_process() from userspace via a syscall
wrapper function. So in normal usage f0 being clobbered across a
syscall doesn't cause visible data corruption.
But there is now a new path, because io-uring can call copy_process()
via create_io_thread() from the signal handling path. That's OK if the
signal is handled as part of syscall return, but it's not OK if the
signal is handled due to some other interrupt.
That path is:
interrupt_return_srr_user()
interrupt_exit_user_prepare()
interrupt_exit_user_prepare_main()
do_notify_resume()
get_signal()
task_work_run()
create_worker_cb()
create_io_worker()
copy_process()
dup_task_struct()
arch_dup_task_struct()
flush_all_to_thread()
save_all()
if (tsk->thread.regs->msr & MSR_FP)
save_fpu()
# f0 is clobbered and potentially live in userspace
Note the above discussion applies equally to save_altivec().

iommu/vt-d: Add MTL to quirk list to skip TE disabling
commit 85b80fdffa867d75dfb9084a839e7949e29064e8 upstream.
The VT-d spec requires (10.4.4 Global Command Register, TE field) that:
Hardware implementations supporting DMA draining must drain any in-flight
DMA read/write requests queued within the Root-Complex before switching
address translation on or off and reflecting the status of the command
through the TES field in the Global Status register.
Unfortunately, some integrated graphic devices fail to do so after some
kind of power state transition. As the result, the system might stuck in
iommu_disable_translation(), waiting for the completion of TE transition.
Add MTL to the quirk list for those devices and skips TE disabling if the
qurik hits.

dm verity: don't perform FEC for failed readahead IO
commit 0193e3966ceeeef69e235975918b287ab093082b upstream.
We found an issue under Android OTA scenario that many BIOs have to do
FEC where the data under dm-verity is 100% complete and no corruption.
Android OTA has many dm-block layers, from upper to lower:
dm-verity
dm-snapshot
dm-origin & dm-cow
dm-linear
ufs
DM tables have to change 2 times during Android OTA merging process.
When doing table change, the dm-snapshot will be suspended for a while.
During this interval, many readahead IOs are submitted to dm_verity
from filesystem. Then the kverity works are busy doing FEC process
which cost too much time to finish dm-verity IO. This causes needless
delay which feels like system is hung.
After adding debugging it was found that each readahead IO needed
around 10s to finish when this situation occurred. This is due to IO
amplification:
dm-snapshot suspend
erofs_readahead // 300+ io is submitted
dm_submit_bio (dm_verity)
dm_submit_bio (dm_snapshot)
bio return EIO
bio got nothing, it's empty
verity_end_io
verity_verify_io
forloop range(0, io->n_blocks) // each io->nblocks ~= 20
verity_fec_decode
fec_decode_rsb
fec_read_bufs
forloop range(0, v->fec->rsn) // v->fec->rsn = 253
new_read
submit_bio (dm_snapshot)
end loop
end loop
dm-snapshot resume
Readahead BIOs get nothing while dm-snapshot is suspended, so all of
them will cause verity's FEC.
Each readahead BIO needs to verify ~20 (io->nblocks) blocks.
Each block needs to do FEC, and every block needs to do 253
(v->fec->rsn) reads.
So during the suspend interval(~200ms), 300 readahead BIOs trigger
~1518000 (300*20*253) IOs to dm-snapshot.
As readahead IO is not required by userspace, and to fix this issue,
it is best to pass readahead errors to upper layer to handle it.

Note the only non-data command is cache flush, which would have resulted in

When in the list_for_each_entry iteration, reload of p->state->settings
with a local setting from old_state will turn the list iteration into an

The typical symptom when the issue happens, will be a printk message like:
"not freeing pin xx (xxx) as part of deactivating group xxx - it is
already used for some other setting".
This is a compiler-dependent problem, one instance occurred using Clang

The Qualcomm glue driver is overriding the interrupt trigger types

This can lead to a failure to map the DP/DM wakeup interrupts after a

type used for the initial mapping:
irq: type mismatch, failed to map hwirq-14 for interrupt-controller@b220000!
irq: type mismatch, failed to map hwirq-15 for interrupt-controller@b220000!
Fix this by not overriding the firmware provided trigger types when
requesting the wakeup interrupts.

usb: dwc3: Fix default mode initialization
commit 10d510abd096d620b9fda2dd3e0047c5efc4ad2b upstream.
The default mode, configurable by DT, shall be set before usb role switch
driver is registered. Otherwise there is a race between default mode
and mode set by usb role switch driver.

USB: dwc2: write HCINT with INTMASK applied
commit 0583bc776ca5b5a3f5752869fc31cf7322df2b35 upstream.
dwc2_hc_n_intr() writes back INTMASK as read but evaluates it
with intmask applied. In stress testing this causes spurious
interrupts like this:

bcache: fixup lock c->root error
commit e34820f984512b433ee1fc291417e60c47d56727 upstream.
We had a problem with io hung because it was waiting for c->root to
release the lock.

The "counter = -4294967297" means that lock count is -1 and a write lock
is being attempted. Then, we found that there is a btree with a counter
of 1 in btree_cache_freeable.

We found that this is a bug in bch_sectors_dirty_init() when locking c->root:
(1). Thread X has locked c->root(A) write.
(2). Thread Y failed to lock c->root(A), waiting for the lock(c->root A).
(3). Thread X bch_btree_set_root() changes c->root from A to B.
(4). Thread X releases the lock(c->root A).
(5). Thread Y successfully locks c->root(A).
(6). Thread Y releases the lock(c->root B).

bcache: fixup init dirty data errors
commit 7cc47e64d3d69786a2711a4767e26b26ba63d7ed upstream.
We found that after long run, the dirty_data of the bcache device
will have errors. This error cannot be eliminated unless re-register.
We also found that reattach after detach, this error can accumulate.
In bch_sectors_dirty_init(), all inode <= d->id keys will be recounted
again. This is wrong, we only need to count the keys of the current
device.

bcache: prevent potential division by zero error
commit 2c7f497ac274a14330208b18f6f734000868ebf9 upstream.
In SHOW(), the variable 'n' is of type 'size_t.' While there is a
conditional check to verify that 'n' is not equal to zero before
executing the 'do_div' macro, concerns arise regarding potential
division by zero error in 64-bit environments.
The concern arises when 'n' is 64 bits in size, greater than zero, and
the lower 32 bits of it are zeros. In such cases, the conditional check
passes because 'n' is non-zero, but the 'do_div' macro casts 'n' to
'uint32_t,' effectively truncating it to its lower 32 bits.
Consequently, the 'n' value becomes zero.
To fix this potential division by zero error and ensure precise
division handling, this commit replaces the 'do_div' macro with
div64_u64(). div64_u64() is designed to work with 64-bit operands,
guaranteeing that division is performed correctly.
This change enhances the robustness of the code, ensuring that division
operations yield accurate results in all scenarios, eliminating the
possibility of division by zero, and improving compatibility across
different 64-bit environments.

bcache: check return value from btree_node_alloc_replacement()
commit 777967e7e9f6f5f3e153abffb562bffaf4430d26 upstream.
In btree_gc_rewrite_node(), pointer 'n' is not checked after it returns
from btree_gc_rewrite_node(). There is potential possibility that 'n' is
a non NULL ERR_PTR(), referencing such error code is not permitted in
following code. Therefore a return value checking is necessary after 'n'
is back from btree_node_alloc_replacement().

dm-delay: fix a race between delay_presuspend and delay_bio
[ Upstream commit 6fc45b6ed921dc00dfb264dc08c7d67ee63d2656 ]
In delay_presuspend, we set the atomic variable may_delay and then stop
the timer and flush pending bios. The intention here is to prevent the
delay target from re-arming the timer again.
However, this test is racy. Suppose that one thread goes to delay_bio,
sees that dc->may_delay is one and proceeds; now, another thread executes
delay_presuspend, it sets dc->may_delay to zero, deletes the timer and
flushes pending bios. Then, the first thread continues and adds the bio to
delayed->list despite the fact that dc->may_delay is false.
Fix this bug by changing may_delay's type from atomic_t to bool and
only access it while holding the delayed_bios_lock mutex. Note that we
don't have to grab the mutex in delay_resume because there are no bios
in flight at this point.

hv_netvsc: Mark VF as slave before exposing it to user-mode
commit c807d6cd089d2f4951baa838081ec5ae3e2360f8 upstream.
When a VF is being exposed form the kernel, it should be marked as "slave"
before exposing to the user-mode. The VF is not usable without netvsc
running as master. The user-mode should never see a VF without the "slave"
flag.
This commit moves the code of setting the slave flag to the time before
VF is exposed to user-mode.

s390/dasd: protect device queue against concurrent access
commit db46cd1e0426f52999d50fa72cfa97fa39952885 upstream.
In dasd_profile_start() the amount of requests on the device queue are
counted. The access to the device queue is unprotected against
concurrent access. With a lot of parallel I/O, especially with alias
devices enabled, the device queue can change while dasd_profile_start()
is accessing the queue. In the worst case this leads to a kernel panic
due to incorrect pointer accesses.
Fix this by taking the device lock before accessing the queue and
counting the requests. Additionally the check for a valid profile data
pointer can be done earlier to avoid unnecessary locking in a hot path.

```
The crash occurred when call wake_up(&state->wait), and then we want
to look at the value in the state. However, bch_sectors_dirty_init()
is not found in the stack of any task. Since state is allocated on
the stack, we guess that bch_sectors_dirty_init() has exited, causing
bch_dirty_init_thread() to be unable to handle kernel paging request.
In order to verify this idea, we added some printing information during
wake_up(&state->wait). We find that "wake up" is printed twice, however
we only expect the last thread to wake up once.
```dmesg
[ 994.641004] alcache: bch_dirty_init_thread() wake up
[ 994.641018] alcache: bch_dirty_init_thread() wake up
[ 994.641523] alcache: bch_sectors_dirty_init() init exit
```
There is a race. If bch_sectors_dirty_init() exits after the first wake
up, the second wake up will trigger this bug("unable to handle kernel
paging request").
Proceed as follows:
bch_sectors_dirty_init
kthread_run ==============> bch_dirty_init_thread(bch_dirtcnt[0])
... ...
atomic_inc(&state.started) ...
... ...
atomic_read(&state.enough) ...
... atomic_set(&state->enough, 1)
kthread_run ======================================================> bch_dirty_init_thread(bch_dirtcnt[1])
... atomic_dec_and_test(&state->started) ...
atomic_inc(&state.started) ... ...
... wake_up(&state->wait) ...
atomic_read(&state.enough) atomic_dec_and_test(&state->started)
... ...
wait_event(state.wait, atomic_read(&state.started) == 0) ...
return ...
wake_up(&state->wait)
We believe it is very common to wake up twice if there is no dirty, but
crash is an extremely low probability event. It's hard for us to reproduce
this issue. We attached and detached continuously for a week, with a total
of more than one million attaches and only one crash.
Putting atomic_inc(&state.started) before kthread_run() can avoid waking
up twice.

swiotlb-xen: provide the "max_mapping_size" method
commit bff2a2d453a1b683378b4508b86b84389f551a00 upstream.
There's a bug that when using the XEN hypervisor with bios with large
multi-page bio vectors on NVMe, the kernel deadlocks [1].
The deadlocks are caused by inability to map a large bio vector -
dma_map_sgtable always returns an error, this gets propagated to the block
layer as BLK_STS_RESOURCE and the block layer retries the request
indefinitely.
XEN uses the swiotlb framework to map discontiguous pages into contiguous
runs that are submitted to the PCIe device. The swiotlb framework has a
limitation on the length of a mapping - this needs to be announced with
the max_mapping_size method to make sure that the hardware drivers do not
create larger mappings.
Without max_mapping_size, the NVMe block driver would create large
mappings that overrun the maximum mapping size.

ACPI: resource: Skip IRQ override on ASUS ExpertBook B1402CVA
commit bd911485294a6f0596e4592ed442438015cffc8a upstream.
Like various other ASUS ExpertBook-s, the ASUS ExpertBook B1402CVA
has an ACPI DSDT table that describes IRQ 1 as ActiveLow while
the kernel overrides it to EdgeHigh.
This prevents the keyboard from working. To fix this issue, add this laptop
to the skip_override_table so that the kernel does not override IRQ 1.

ASoC: simple-card: fixup asoc_simple_probe() error handling
commit 41bae58df411f9accf01ea660730649b2fab1dab upstream.
asoc_simple_probe() is used for both "DT probe" (A) and "platform probe"
(B). It uses "goto err" when error case, but it is not needed for
"platform probe" case (B). Thus it is using "return" directly there.
static int asoc_simple_probe(...)
{
^ if (...) {
| ...
(A) if (ret < 0)
| goto err;
v } else {
^ ...
| if (ret < 0)
(B) return -Exxx;
v }
...
^ if (ret < 0)
(C) goto err;
v ...
err:
(D) simple_util_clean_reference(card);
return ret;
}
Both case are using (C) part, and it calls (D) when err case.
But (D) will do nothing for (B) case.
Because of these behavior, current code itself is not wrong,
but is confusable, and more, static analyzing tool will warning on
(B) part (should use goto err).
To avoid static analyzing tool warning, this patch uses "goto err"
on (B) part.

The flow of issue triggering is as follows:
1. remove es
raw es es removed es1
|-------------------| -> |----|.......|------|
2. insert es
es insert es1 merge with es es1 merge with es and free es1
|----|.......|------| -> |------------|------| -> |-------------------|
es merges with newes, then merges with es1, frees es1, then determines
if es1->es_len is 0 and triggers a UAF.
The code flow is as follows:
ext4_es_insert_extent
es1 = __es_alloc_extent(true);
es2 = __es_alloc_extent(true);
__es_remove_extent(inode, lblk, end, NULL, es1)
__es_insert_extent(inode, &newes, es1) ---> insert es1 to es tree
__es_insert_extent(inode, &newes, es2)
ext4_es_try_to_merge_right
ext4_es_free_extent(inode, es1) ---> es1 is freed
if (es1 && !es1->es_len)
// Trigger UAF by determining if es1 is used.
We determine whether es1 or es2 is used immediately after calling
__es_remove_extent() or __es_insert_extent() to avoid triggering a
UAF if es1 or es2 is freed.

ext4: using nofail preallocation in ext4_es_remove_extent()
[ Upstream commit e9fe2b882bd5b26b987c9ba110c2222796f72af5 ]
If __es_remove_extent() returns an error it means that when splitting
extent, allocating an extent that must be kept failed, where returning
an error directly would cause the extent tree to be inconsistent. So we
use GFP_NOFAIL to pre-allocate an extent_status and pass it to
__es_remove_extent() to avoid this problem.
In addition, since the allocated memory is outside the i_es_lock, the
extent_status tree may change and the pre-allocated extent_status is
no longer needed, so we release the pre-allocated extent_status when
es->es_len is not initialized.

ext4: use pre-allocated es in __es_remove_extent()
[ Upstream commit bda3efaf774fb687c2b7a555aaec3006b14a8857 ]
When splitting extent, if the second extent can not be dropped, we return
-ENOMEM and use GFP_NOFAIL to preallocate an extent_status outside of
i_es_lock and pass it to __es_remove_extent() to be used as the second
extent. This ensures that __es_remove_extent() is executed successfully,
thus ensuring consistency in the extent status tree. If the second extent
is not undroppable, we simply drop it and return 0. Then retry is no longer
necessary, remove it.
Now, __es_remove_extent() will always remove what it should, maybe more.

ext4: factor out __es_alloc_extent() and __es_free_extent()
[ Upstream commit 73a2f033656be11298912201ad50615307b4477a ]
Factor out __es_alloc_extent() and __es_free_extent(), which only allocate
and free extent_status in these two helpers.
The ext4_es_alloc_extent() function is split into __es_alloc_extent()
and ext4_es_init_extent(). In __es_alloc_extent() we allocate memory using
GFP_KERNEL | __GFP_NOFAIL | __GFP_ZERO if the memory allocation cannot
fail, otherwise we use GFP_ATOMIC. and the ext4_es_init_extent() is used to
initialize extent_status and update related variables after a successful
allocation.
This is to prepare for the use of pre-allocated extent_status later.

In the extent status tree, we have extents which we can just drop without
issues and extents we must not drop - this depends on the extent's status
- currently ext4_es_is_delayed() extents must stay, others may be dropped.
A helper function is added to help determine if the current extent can
be dropped, although only ext4_es_is_delayed() extents cannot be dropped
currently.

lockdep: Fix block chain corruption

That would mean @size == 0, at which point size_to_bucket() returns -1
and the above happens.
alloc_chain_hlocks() has 'size - req', for the first with the
precondition 'size >= rq', which allows the 0.
This code is trying to split a block, del_chain_block() takes what we
need, and add_chain_block() puts back the remainder, except in the
above case the remainder is 0 sized and things go sideways.

The driver needs to deregister and free the newly allocated dwc3 core
platform device on ACPI probe errors (e.g. probe deferral) and on driver
unbind but instead it leaked those resources while erroneously dropping
a reference to the parent platform device which is still in use.

device which has also always been leaked.

afs: Fix file locking on R/O volumes to operate in local mode
[ Upstream commit b590eb41be766c5a63acc7e8896a042f7a4e8293 ]
AFS doesn't really do locking on R/O volumes as fileservers don't maintain
state with each other and thus a lock on a R/O volume file on one
fileserver will not be be visible to someone looking at the same file on
another fileserver.
Further, the server may return an error if you try it.
Fix this by doing what other AFS clients do and handle filelocking on R/O
volume files entirely within the client and don't touch the server.

amd-xgbe: handle the corner-case during tx completion
[ Upstream commit 7121205d5330c6a3cb3379348886d47c77b78d06 ]
The existing implementation uses software logic to accumulate tx
completions until the specified time (1ms) is met and then poll them.
However, there exists a tiny gap which leads to a race between
resetting and checking the tx_activate flag. Due to this the tx
completions are not reported to upper layer and tx queue timeout
kicks-in restarting the device.
To address this, introduce a tx cleanup mechanism as part of the
periodic maintenance process.

Force the mode change for SFI in Fixed PHY configurations. Fixed PHY
configurations needs PLL to be enabled while doing mode set. When the
SFP module isn't connected during boot, driver assumes AN is ON and
attempts auto-negotiation. However, if the connected SFP comes up in
Fixed PHY configuration the link will not come up as PLL isn't enabled
while the initial mode set command is issued. So, force the mode change
for SFI in Fixed PHY configuration to fix link issues.

net/smc: avoid data corruption caused by decline
[ Upstream commit e6d71b437abc2f249e3b6a1ae1a7228e09c6e563 ]
We found a data corruption issue during testing of SMC-R on Redis
applications.
The benchmark has a low probability of reporting a strange error as
shown below.
"Error: Protocol error, got "\xe2" as reply type byte"
Finally, we found that the retrieved error data was as follows:
0xE2 0xD4 0xC3 0xD9 0x04 0x00 0x2C 0x20 0xA6 0x56 0x00 0x16 0x3E 0x0C
0xCB 0x04 0x02 0x01 0x00 0x00 0x20 0x00 0x00 0x00 0x00 0x00 0x00 0x00
0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0xE2
It is quite obvious that this is a SMC DECLINE message, which means that
the applications received SMC protocol message.
We found that this was caused by the following situations:
client server
¦ clc proposal
------------->
¦ clc accept
<-------------
¦ clc confirm
------------->
wait llc confirm
send llc confirm
¦failed llc confirm
¦ x------
(after 2s)timeout
wait llc confirm rsp
wait decline
(after 1s) timeout
(after 2s) timeout
¦ decline
-------------->
¦ decline
<--------------
As a result, a decline message was sent in the implementation, and this
message was read from TCP by the already-fallback connection.
This patch double the client timeout as 2x of the server value,
With this simple change, the Decline messages should never cross or
collide (during Confirm link timeout).
This issue requires an immediate solution, since the protocol updates
involve a more long-term solution.

net: usb: ax88179_178a: fix failed operations during ax88179_reset
[ Upstream commit 0739af07d1d947af27c877f797cb82ceee702515 ]
Using generic ASIX Electronics Corp. AX88179 Gigabit Ethernet device,
the following test cycle has been implemented:
- power on
- check logs
- shutdown
- after detecting the system shutdown, disconnect power
- after approximately 60 seconds of sleep, power is restored
Running some cycles, sometimes error logs like this appear:
kernel: ax88179_178a 2-9:1.0 (unnamed net_device) (uninitialized): Failed to write reg index 0x0001: -19
kernel: ax88179_178a 2-9:1.0 (unnamed net_device) (uninitialized): Failed to read reg index 0x0001: -19
...
These failed operation are happening during ax88179_reset execution, so
the initialization could not be correct.
In order to avoid this, we need to increase the delay after reset and
clock initial operations. By using these larger values, many cycles
have been run and no failed operations appear.
It would be better to check some status register to verify when the
operation has finished, but I do not have found any available information
(neither in the public datasheets nor in the manufacturer's driver). The
only available information for the necessary delays is the maufacturer's
driver (original values) but the proposed values are not enough for the
tested devices.

afs: Make error on cell lookup failure consistent with OpenAFS
[ Upstream commit 2a4ca1b4b77850544408595e2433f5d7811a9daa ]
When kafs tries to look up a cell in the DNS or the local config, it will
translate a lookup failure into EDESTADDRREQ whereas OpenAFS translates it
into ENOENT. Applications such as West expect the latter behaviour and
fail if they see the former.
This can be seen by trying to mount an unknown cell:
# mount -t afs %example.com:cell.root /mnt
mount: /mnt: mount(2) system call failed: Destination address required.

afs: Fix afs_server_list to be cleaned up with RCU
[ Upstream commit e6bace7313d61e31f2b16fa3d774fd8cb3cb869e ]
afs_server_list is accessed with the rcu_read_lock() held from
volume->servers, so it needs to be cleaned up correctly.
Fix this by using kfree_rcu() instead of kfree().

PCI: keystone: Drop __init from ks_pcie_add_pcie_{ep,port}()
This commit has no upstream equivalent.
After commit db5ebaeb8fda ("PCI: keystone: Don't discard .probe()
callback") in 5.10.202, there are two modpost warnings when building with
clang:
WARNING: modpost: vmlinux.o(.text+0x5aa6dc): Section mismatch in reference from the function ks_pcie_probe() to the function .init.text:ks_pcie_add_pcie_port()
The function ks_pcie_probe() references
the function __init ks_pcie_add_pcie_port().
This is often because ks_pcie_probe lacks a __init
annotation or the annotation of ks_pcie_add_pcie_port is wrong.
WARNING: modpost: vmlinux.o(.text+0x5aa6f4): Section mismatch in reference from the function ks_pcie_probe() to the function .init.text:ks_pcie_add_pcie_ep()
The function ks_pcie_probe() references
the function __init ks_pcie_add_pcie_ep().
This is often because ks_pcie_probe lacks a __init
annotation or the annotation of ks_pcie_add_pcie_ep is wrong.
ks_pcie_add_pcie_ep() was removed in upstream commit a0fd361db8e5 ("PCI:
dwc: Move "dbi", "dbi2", and "addr_space" resource setup into common
code") and ks_pcie_add_pcie_port() was removed in upstream
commit 60f5b73fa0f2 ("PCI: dwc: Remove unnecessary wrappers around
dw_pcie_host_init()"), both of which happened before upstream
commit 7994db905c0f ("PCI: keystone: Don't discard .probe() callback").
As neither of these removal changes are really suitable for stable, just
remove __init from these functions in stable, as it is no longer a
correct annotation after dropping __init from ks_pcie_probe().

RDMA/irdma: Prevent zero-length STAG registration
commit bb6d73d9add68ad270888db327514384dfa44958 upstream.
Currently irdma allows zero-length STAGs to be programmed in HW during
the kernel mode fast register flow. Zero-length MR or STAG registration
disable HW memory length checks.
Improve gaps in bounds checking in irdma by preventing zero-length STAG or
MR registrations except if the IB_PD_UNSAFE_GLOBAL_RKEY is set.
This addresses the disclosure CVE-2023-25775.
