Transfer events without TRB"
This reverts commit 9a24eb8010c2dc6a2eba56e3eb9fc07d14ffe00a which is
commit 66cb618bf0bb82859875b00eeffaf223557cb416 upstream.
In backporting it to stable kernels, it causes a severe regression on
many systems, so revert it for now.

commit 93aef9eda1cea9e84ab2453fcceb8addad0e46f1 upstream.
If the bitmap block that manages the inode allocation status is corrupted,
nilfs_ifile_create_inode() may allocate a new inode from the reserved
inode area where it should not be allocated.
Previous fix commit d325dc6eb763 ("nilfs2: fix use-after-free bug of
struct nilfs_root"), fixed the problem that reserved inodes with inode
numbers less than NILFS_USER_INO (=11) were incorrectly reallocated due to
bitmap corruption, but since the start number of non-reserved inodes is
read from the super block and may change, in which case inode allocation
may occur from the extended reserved inode area.
If that happens, access to that inode will cause an IO error, causing the
file system to degrade to an error state.
Fix this potential issue by adding a wraparound option to the common
metadata object allocation routine and by modifying
nilfs_ifile_create_inode() to disable the option so that it only allocates
inodes with inode numbers greater than or equal to the inode number read
in "nilfs->ns_first_ino", regardless of the bitmap status of reserved
inodes.

[ Upstream commit b164316808ec5de391c3e7b0148ec937d32d280d ]
A zoned device with a smaller last zone together with a zone capacity
smaller than the zone size does make any sense as that does not
correspond to any possible setup for a real device:
1) For ZNS and zoned UFS devices, all zones are always the same size.
2) For SMR HDDs, all zones always have the same capacity.
In other words, if we have a smaller last runt zone, then this zone
capacity should always be equal to the zone size.
Add a check in null_init_zoned_dev() to prevent a configuration to have
both a smaller zone size and a zone capacity smaller than the zone size.

[ Upstream commit bc42ca002d5d211f9c57334b9b4c25ddb0b4ec35 ]
When an inquiry of the current protocol via UMP Stream Configuration
message fails by some reason, we may leave the current protocol
undefined, which may lead to unexpected behavior. Better to assume a
valid protocol found in the protocol capability bits instead.
For a device that doesn't support the UMP v1.2 feature, it won't reach
to this code path, and USB MIDI GTB descriptor would be used for
determining the protocol, instead.

[ Upstream commit 4a69c1264ff41bc5bf7c03101ada0454fbf08868 ]
During dummy-cycles xSPI will switch GPIO into Hi-Z mode. In that dummy
period voltage on data lines will slowly drop, what can cause
unintentional modebyte transmission. Value send to SPI memory chip will
depend on last address, and clock frequency.
To prevent unforeseen consequences of that behaviour, force send
single modebyte(0x00).
Modebyte will be send only if number of dummy-cycles is not equal
to 0. Code must also reduce dummycycle byte count by one - as one byte
is send as modebyte.

Syzbot constructed a write() call with a data length of 3 bytes but a count value

Therefore, increasing the comparison between data length and count value to avoid

[ Upstream commit c758b77d4a0a0ed3a1292b3fd7a2aeccd1a169a4 ]
In nvmet_sq_destroy we capture sq->ctrl early and if it is non-NULL we
know that a ctrl was allocated (in the admin connect request handler)
and we need to release pending AERs, clear ctrl->sqs and sq->ctrl
(for nvme-loop primarily), and drop the final reference on the ctrl.
However, a small window is possible where nvmet_sq_destroy starts (as
a result of the client giving up and disconnecting) concurrently with
the nvme admin connect cmd (which may be in an early stage). But *before*
kill_and_confirm of sq->ref (i.e. the admin connect managed to get an sq
live reference). In this case, sq->ctrl was allocated however after it was
captured in a local variable in nvmet_sq_destroy.
This prevented the final reference drop on the ctrl.
Solve this by re-capturing the sq->ctrl after all inflight request has
completed, where for sure sq->ctrl reference is final, and move forward
based on that.
This issue was observed in an environment with many hosts connecting
multiple ctrls simoutanuosly, creating a delay in allocating a ctrl
leading up to this race window.

[ Upstream commit 611b7eb19d0a305d4de00280e4a71a1b15c507fc ]
Currently, when an adapter defines a max_write_len quirk,
the data will be chunked into data sizes equal to the
max_write_len quirk value. But the payload will be increased by
the size of the register address before transmission. The
resulting value always ends up larger than the limit set
by the quirk.
Avoid this error by setting regmap's max_write to the quirk's
max_write_len minus the number of bytes for the register and
padding. This allows the chunking to work correctly for this
limited case without impacting other use-cases.

bio_vec start offset may be relatively large particularly when large
folio gets added to the bio. A bigger offset will result in avoiding the
single-segment mapping optimization and end up using expensive
mempool_alloc further.
Rather than using absolute value, adjust bv_offset by
NVME_CTRL_PAGE_SIZE while checking if segment can be fitted into one/two
PRP entries.

[ Upstream commit d3a043733f25d743f3aa617c7f82dbcb5ee2211a ]
In current native multipath design when a shared namespace is created,
we loop through each possible numa-node, calculate the NUMA distance of
that node from each nvme controller and then cache the optimal IO path
for future reference while sending IO. The issue with this design is that
we may refer to the NUMA distance table for an offline node which may not
be populated at the time and so we may inadvertently end up finding and
caching a non-optimal path for IO. Then latter when the corresponding
numa-node becomes online and hence the NUMA distance table entry for that
node is created, ideally we should re-calculate the multipath node distance
for the newly added node however that doesn't happen unless we rescan/reset
the controller. So essentially, we may keep using non-optimal IO path for a
node which is made online after namespace is created.
This patch helps fix this issue ensuring that when a shared namespace is
created, we calculate the multipath node distance for each online numa-node
instead of each possible numa-node. Then latter when a node becomes online
and we receive any IO on that newly added node, we would calculate the
multipath node distance for newly added node but this time NUMA distance
table would have been already populated for newly added node. Hence we
would be able to correctly calculate the multipath node distance and choose
the optimal path for the IO.

[ Upstream commit b1b2ce58ed23c5d56e0ab299a5271ac01f95b75c ]
Currently, we can try to queue an event's work before the vhost_task is
created. When this happens we just drop it in vhost_scsi_do_plug before
even calling vhost_vq_work_queue. During a device shutdown we do the
same thing after vhost_scsi_clear_endpoint has cleared the backends.
In the next patches we will be able to kill the vhost_task before we
have cleared the endpoint. In that case, vhost_vq_work_queue can fail
and we will leak the event's memory. This has handle the failure by
just freeing the event. This is safe to do, because
vhost_vq_work_queue will only return failure for us when the vhost_task
is killed and so userspace will not be able to handle events if we
sent them.

Commit 2f7b1d8b5505 ("clk: mediatek: Do a runtime PM get on controllers
during probe") enabled runtime PM for all mediatek clock controllers,
but this introduced an issue on the resume path.
If a device resumes earlier than the clock controller and calls
clk_prepare() when runtime PM is enabled on the controller, it will end
up calling clk_pm_runtime_get(). But the subsequent
pm_runtime_resume_and_get() call will fail because the runtime PM is
temporarily disabled during suspend.
To workaround this, introduce a need_runtime_pm flag and only enable it
on mt8183-mfgcfg, which is the driver that observed deadlock previously.
Hopefully mt8183-cfgcfg won't run into the issue at the resume stage
because the GPU should have stopped rendering before the system calls
suspend.

Both gpll6 and gpll7 are parented to CXO at 19.2 MHz and not to GPLL0
which runs at 600 MHz. Also gpll6_out_even should have the parent gpll6

Adjust the parents of these clocks to make Linux report the correct rate
and not absurd numbers like gpll7 at ~25 GHz or gpll6 at 24 GHz.
Corrected rates are the following:

gpll6 768000000 Hz
gpll6_out_even 384000000 Hz
gpll0 600000000 Hz
gpll0_out_odd 200000000 Hz
gpll0_out_even 300000000 Hz
And because gpll6 is the parent of gcc_sdcc2_apps_clk_src (at 202 MHz)
that clock also reports the correct rate now and avoids this warning:

Commit c7423dbdbc9e ("ima: Handle -ESTALE returned by
ima_filter_rule_match()") introduced call to ima_lsm_copy_rule within a
RCU read-side critical section which contains kmalloc with GFP_KERNEL.
This implies a possible sleep and violates limitations of RCU read-side
critical sections on non-PREEMPT systems.
Sleeping within RCU read-side critical section might cause
synchronize_rcu() returning early and break RCU protection, allowing a
UAF to happen.
The root cause of this issue could be described as follows:
| Thread A | Thread B |
| |ima_match_policy |
| | rcu_read_lock |
|ima_lsm_update_rule | |
| synchronize_rcu | |
| | kmalloc(GFP_KERNEL)|
| | sleep |
==> synchronize_rcu returns early
| kfree(entry) | |
| | entry = entry->next|
==> UAF happens and entry now becomes NULL (or could be anything).
| | entry->action |
==> Accessing entry might cause panic.
To fix this issue, we are converting all kmalloc that is called within
RCU read-side critical section to use GFP_ATOMIC.

commit d201c92bff90f3d3d0b079fc955378c15c0483cc upstream.
Correct the specified regulator-min-microvolt value for the buck DCDC_REG2
regulator, which is part of the Rockchip RK809 PMIC, in the Pine64 Quartz64
Model B board dts. According to the RK809 datasheet, version 1.01, this
regulator is capable of producing voltages as low as 0.5 V on its output,
instead of going down to 0.9 V only, which is additionally confirmed by the
regulator-min-microvolt values found in the board dts files for the other
supported boards that use the same RK809 PMIC.
This allows the DVFS to clock the GPU on the Quartz64 Model B below 700 MHz,
all the way down to 200 MHz, which saves some power and reduces the amount of
generated heat a bit, improving the thermal headroom and possibly improving
the bursty CPU and GPU performance on this board.
This also eliminates the following warnings in the kernel log:
core: _opp_supported_by_regulators: OPP minuV: 825000 maxuV: 825000, not supported by regulator
panfrost fde60000.gpu: _opp_add: OPP not supported by regulators (200000000)

commit 134061163ee5ca4759de5c24ca3bd71608891ba7 upstream.
Fix UBSAN warnings that occur when using a system with 32 physical
cpu cores or more, or when the user defines a number of Ethernet
queues greater than or equal to FP_SB_MAX_E1x using the num_queues
module parameter.
Currently there is a read/write out of bounds that occurs on the array
"struct stats_query_entry query" present inside the "bnx2x_fw_stats_req"
struct in "drivers/net/ethernet/broadcom/bnx2x/bnx2x.h".
Looking at the definition of the "struct stats_query_entry query" array:
struct stats_query_entry query[FP_SB_MAX_E1x+
BNX2X_FIRST_QUEUE_QUERY_IDX];
FP_SB_MAX_E1x is defined as the maximum number of fast path interrupts and
has a value of 16, while BNX2X_FIRST_QUEUE_QUERY_IDX has a value of 3
meaning the array has a total size of 19.
Since accesses to "struct stats_query_entry query" are offset-ted by
BNX2X_FIRST_QUEUE_QUERY_IDX, that means that the total number of Ethernet
queues should not exceed FP_SB_MAX_E1x (16). However one of these queues
is reserved for FCOE and thus the number of Ethernet queues should be set
to [FP_SB_MAX_E1x -1] (15) if FCOE is enabled or [FP_SB_MAX_E1x] (16) if
it is not.
This is also described in a comment in the source code in
drivers/net/ethernet/broadcom/bnx2x/bnx2x.h just above the Macro definition
of FP_SB_MAX_E1x. Below is the part of this explanation that it important
for this patch
/*
* The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is
* control by the number of fast-path status blocks supported by the
* device (HW/FW). Each fast-path status block (FP-SB) aka non-default
* status block represents an independent interrupts context that can
* serve a regular L2 networking queue. However special L2 queues such
* as the FCoE queue do not require a FP-SB and other components like
* the CNIC may consume FP-SB reducing the number of possible L2 queues
*
* If the maximum number of FP-SB available is X then:
* a. If CNIC is supported it consumes 1 FP-SB thus the max number of
* regular L2 queues is Y=X-1
* b. In MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
* c. If the FCoE L2 queue is supported the actual number of L2 queues
* is Y+1
* d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
* slow-path interrupts) or Y+2 if CNIC is supported (one additional
* FP interrupt context for the CNIC).
* e. The number of HW context (CID count) is always X or X+1 if FCoE
* L2 queue is supported. The cid for the FCoE L2 queue is always X.
*/
However this driver also supports NICs that use the E2 controller which can
handle more queues due to having more FP-SB represented by FP_SB_MAX_E2.
Looking at the commits when the E2 support was added, it was originally
using the E1x parameters: commit f2e0899f0f27 ("bnx2x: Add 57712 support").
Back then FP_SB_MAX_E2 was set to 16 the same as E1x. However the driver
was later updated to take full advantage of the E2 instead of having it be
limited to the capabilities of the E1x. But as far as we can tell, the
array "stats_query_entry query" was still limited to using the FP-SB
available to the E1x cards as part of an oversignt when the driver was
updated to take full advantage of the E2, and now with the driver being
aware of the greater queue size supported by E2 NICs, it causes the UBSAN
warnings seen in the stack traces below.
This patch increases the size of the "stats_query_entry query" array by
replacing FP_SB_MAX_E1x with FP_SB_MAX_E2 to be large enough to handle
both types of NICs.

commit 8754d9835683e8fab9a8305acdb38a3aeb9d20bd upstream.
Early during NAND identification, mtd_info fields have not yet been
initialized (namely, writesize and oobsize) and thus cannot be used for
sanity checks yet. Of course if there is a misuse of
nand_change_read_column_op() so early we won't be warned, but there is
anyway no actual check to perform at this stage as we do not yet know
the NAND geometry.
So, if the fields are empty, especially mtd->writesize which is *always*
set quite rapidly after identification, let's skip the sanity checks.
nand_change_read_column_op() is subject to be used early for ONFI/JEDEC
identification in the very unlikely case of:
- bitflips appearing in the parameter page,
- the controller driver not supporting simple DATA_IN cycles.
As nand_change_read_column_op() uses nand_fill_column_cycles() the logic
explaind above also applies in this secondary helper.

commit 5da39530d19946f6241de84d1db69da2f5c61da7 upstream.
The nand_read_data_op() operation, which only consists in DATA_IN
cycles, is sadly not supported by all controllers despite being very
basic. The core, for some time, supposed all drivers would support
it. An improvement to this situation for supporting more constrained
controller added a check to verify if the operation was supported before
attempting it by running the function with the check_only boolean set
first, and then possibly falling back to another (possibly slightly less
optimized) alternative.
An even newer addition moved that check very early and probe time, in
order to perform the check only once. The content of the operation was
not so important, as long as the controller driver would tell whether
such operation on the NAND bus would be possible or not. In practice, no
buffer was provided (no fake buffer or whatever) as it is anyway not
relevant for the "check_only" condition. Unfortunately, early in the
function, there is an if statement verifying that the input parameters
are right for normal use, making the early check always unsuccessful.

commit 3a1b777eb9fb75d09c45ae5dd1d007eddcbebf1f upstream.
Until recently the "upper layer" was MTD. But following incremental
reworks to bring spi-nand support and more recently generic ECC support,
there is now an intermediate "generic NAND" layer that also needs to get
access to some values. When using "converted" ECC engines, like the
software ones, these values are already propagated correctly. But
otherwise when using good old raw NAND controller drivers, we need to
manually set these values ourselves at the end of the "scan" operation,
once these values have been negotiated.
Without this propagation, later (generic) checks like the one warning
users that the ECC strength is not high enough might simply no longer
work.

commit 13fc6c175924eaa953cf597ce28ffa4edc4554a6 upstream.
According to the code logic, when the kernel is loaded at address 0, no
copying operation should be performed, but it is currently being done.
This patch fixes the issue where the kernel code was incorrectly
duplicated to address 0 when booting from address 0.

commit 21a741eb75f80397e5f7d3739e24d7d75e619011 upstream.
kexec on pseries disables AIL (reloc_on_exc), required for scv
instruction support, before other CPUs have been shut down. This means
they can execute scv instructions after AIL is disabled, which causes an
interrupt at an unexpected entry location that crashes the kernel.
Change the kexec sequence to disable AIL after other CPUs have been
brought down.
As a refresher, the real-mode scv interrupt vector is 0x17000, and the
fixed-location head code probably couldn't easily deal with implementing
such high addresses so it was just decided not to support that interrupt
at all.

commit ea977d742507e534d9fe4f4d74256f6b7f589338 upstream.
In order to set the rate range of a hw sunxi_ccu_probe calls
hw_to_ccu_common() assuming all entries in desc->ccu_clks are contained
in a ccu_common struct. This assumption is incorrect and, in
consequence, causes invalid pointer de-references.
Remove the faulty call. Instead, add one more loop that iterates over
the ccu_clks and sets the rate range, if required.

commit 72ceafb587a56e26c905472418c7dc2033c294d3 upstream.
The crypto_ahb and crypto_axi clks are hardware voteable.
This means that the halt bit isn't reliable because some
other voter in the system, e.g. TrustZone, could be keeping
the clk enabled when the kernel turns it off from clk_disable().
Make these clks use voting mode by changing the halt check to
BRANCH_HALT_VOTED and toggle the voting bit in the voting register
instead of directly controlling the branch by writing to the branch
register. This fixes stuck clk warnings seen on ipq9574 and saves
power by actually turning the clk off.
Also changes the CRYPTO_AHB_CLK_ENA & CRYPTO_AXI_CLK_ENA
offset to 0xb004 from 0x16014.

commit 30139c702048f1097342a31302cbd3d478f50c63 upstream.
Patch series "mm: Avoid possible overflows in dirty throttling".
Dirty throttling logic assumes dirty limits in page units fit into
32-bits. This patch series makes sure this is true (see patch 2/2 for
more details).
This patch (of 2):
This reverts commit 9319b647902cbd5cc884ac08a8a6d54ce111fc78.
The commit is broken in several ways. Firstly, the removed (u64) cast
from the multiplication will introduce a multiplication overflow on 32-bit
archs if wb_thresh * bg_thresh >= 1<<32 (which is actually common - the
default settings with 4GB of RAM will trigger this). Secondly, the
div64_u64() is unnecessarily expensive on 32-bit archs. We have
div64_ul() in case we want to be safe & cheap. Thirdly, if dirty
thresholds are larger than 1<<32 pages, then dirty balancing is going to
blow up in many other spectacular ways anyway so trying to fix one
possible overflow is just moot.

Currently we will not generate FS_OPEN events for O_PATH file
descriptors but we will generate FS_CLOSE events for them. This is
asymmetry is confusing. Arguably no fsnotify events should be generated
for O_PATH file descriptors as they cannot be used to access or modify
file content, they are just convenient handles to file objects like
paths. So fix the asymmetry by stopping to generate FS_CLOSE for O_PATH
file descriptors.

commit 88e72239ead9814b886db54fc4ee39ef3c2b8f26 upstream.
Commit 272970be3dab ("Bluetooth: hci_qca: Fix driver shutdown on closed
serdev") will cause below regression issue:
BT can't be enabled after below steps:
cold boot -> enable BT -> disable BT -> warm reboot -> BT enable failure
if property enable-gpios is not configured within DT|ACPI for QCA6390.
The commit is to fix a use-after-free issue within qca_serdev_shutdown()
by adding condition to avoid the serdev is flushed or wrote after closed
but also introduces this regression issue regarding above steps since the
VSC is not sent to reset controller during warm reboot.
Fixed by sending the VSC to reset controller within qca_serdev_shutdown()
once BT was ever enabled, and the use-after-free issue is also fixed by
this change since the serdev is still opened before it is flushed or wrote.

reclaim
commit 48f091fd50b2eb33ae5eaea9ed3c4f81603acf38 upstream.
There is a potential parallel list adding for retrying in
btrfs_reclaim_bgs_work and adding to the unused list. Since the block
group is removed from the reclaim list and it is on a relocation work,
it can be added into the unused list in parallel. When that happens,
adding it to the reclaim list will corrupt the list head and trigger
list corruption like below.
Fix it by taking fs_info->unused_bgs_lock.

There is a similar retry_list code in btrfs_delete_unused_bgs(), but it is
safe, AFAICS. Since the block group was in the unused list, the used bytes
should be 0 when it was added to the unused list. Then, it checks
block_group->{used,reserved,pinned} are still 0 under the
block_group->lock. So, they should be still eligible for the unused list,
not the reclaim list.
The reason it is safe there it's because because we're holding
space_info->groups_sem in write mode.
That means no other task can allocate from the block group, so while we
are at deleted_unused_bgs() it's not possible for other tasks to
allocate and deallocate extents from the block group, so it can't be
added to the unused list or the reclaim list by anyone else.
The bug can be reproduced by btrfs/166 after a few rounds. In practice
this can be hit when relocation cannot find more chunk space and ends
with ENOSPC.

commit 385d838df280eba6c8680f9777bfa0d0bfe7e8b2 upstream.
The dirty throttling logic is interspersed with assumptions that dirty
limits in PAGE_SIZE units fit into 32-bit (so that various multiplications
fit into 64-bits). If limits end up being larger, we will hit overflows,
possible divisions by 0 etc. Fix these problems by never allowing so
large dirty limits as they have dubious practical value anyway. For
dirty_bytes / dirty_background_bytes interfaces we can just refuse to set
so large limits. For dirty_ratio / dirty_background_ratio it isn't so
simple as the dirty limit is computed from the amount of available memory
which can change due to memory hotplug etc. So when converting dirty
limits from ratios to numbers of pages, we just don't allow the result to
exceed UINT_MAX.
This is root-only triggerable problem which occurs when the operator
sets dirty limits to >16 TB.
