commit 47f33c27fc9565fb0bc7dfb76be08d445cd3d236 upstream.
dm-ebs uses dm-bufio to process requests that are not aligned on logical
sector size. dm-bufio doesn't support passing integrity data (and it is
unclear how should it do it), so we shouldn't set the
DM_TARGET_PASSES_INTEGRITY flag.

commit 80f130bfad1dab93b95683fc39b87235682b8f72 upstream.
The documentation in rculist.h explains the absence of list_empty_rcu()
and cautions programmers against relying on a list_empty() ->
list_first() sequence in RCU safe code. This is because each of these
functions performs its own READ_ONCE() of the list head. This can lead
to a situation where the list_empty() sees a valid list entry, but the
subsequent list_first() sees a different view of list head state after a
modification.
In the case of dm-thin, this author had a production box crash from a GP
fault in the process_deferred_bios path. This function saw a valid list
head in get_first_thin() but when it subsequently dereferenced that and
turned it into a thin_c, it got the inside of the struct pool, since the
list was now empty and referring to itself. The kernel on which this
occurred printed both a warning about a refcount_t being saturated, and
a UBSAN error for an out-of-bounds cpuid access in the queued spinlock,
prior to the fault itself. When the resulting kdump was examined, it
was possible to see another thread patiently waiting in thin_dtr's
synchronize_rcu.
The thin_dtr call managed to pull the thin_c out of the active thins
list (and have it be the last entry in the active_thins list) at just
the wrong moment which lead to this crash.
Fortunately, the fix here is straight forward. Switch get_first_thin()
function to use list_first_or_null_rcu() which performs just a single
READ_ONCE() and returns NULL if the list is already empty.
This was run against the devicemapper test suite's thin-provisioning
suites for delete and suspend and no regressions were observed.

[ Upstream commit 7e25044b804581b9c029d5a28d8800aebde18043 ]
The 'np' device_node is initialized via of_cpu_device_node_get(), which
requires explicit calls to of_node_put() when it is no longer required
to avoid leaking the resource.
Instead of adding the missing calls to of_node_put() in all execution
paths, use the cleanup attribute for 'np' by means of the __free()
macro, which automatically calls of_node_put() when the variable goes
out of scope. Given that 'np' is only used within the
for_each_possible_cpu(), reduce its scope to release the nood after
every iteration of the loop.

The kafs filesystem limits the maximum length of a cell to 256 bytes, but a
problem occurs if someone actually does that: kafs tries to create a
directory under /proc/net/afs/ with the name of the cell, but that fails
with a warning:
WARNING: CPU: 0 PID: 9 at fs/proc/generic.c:405
because procfs limits the maximum filename length to 255.
However, the DNS limits the maximum lookup length and, by extension, the
maximum cell name, to 255 less two (length count and trailing NUL).
Fix this by limiting the maximum acceptable cellname length to 253. This
also allows us to be sure we can create the "/afs/.<cell>/" mountpoint too.
Further, split the YFS VL record cell name maximum to be the 256 allowed by
the protocol and ignore the record retrieved by YFSVL.GetCellName if it
exceeds 253.

In the smb2_send_interim_resp(), if ksmbd_alloc_work_struct()
fails to allocate a node, it returns a NULL pointer to the
in_work pointer. This can lead to an illegal memory write of
in_work->response_buf when allocate_interim_rsp_buf() attempts
to perform a kzalloc() on it.
To address this issue, incorporating a check for the return
value of ksmbd_alloc_work_struct() ensures that the function
returns immediately upon allocation failure, thereby preventing
the aforementioned illegal memory access.

After DP passes link training, it can express the lane count of the
current link status is good. Calculate the maximum bandwidth supported
by DP using the current lane count.
The color format will select the best one based on the bandwidth
requirements of the current timing mode. If the current timing mode
uses RGB and meets the DP link bandwidth requirements, RGB will be used.
If the timing mode uses RGB but does not meet the DP link bandwidthi
requirements, it will continue to check whether YUV422 meets
the DP link bandwidth.
FEC overhead is approximately 2.4% from DP 1.4a spec 2.2.1.4.2.
The down-spread amplitude shall either be disabled (0.0%) or up
to 0.5% from 1.4a 3.5.2.6. Add up to approximately 3% total overhead.

Even though we fixed a logic error in the commit cited below, syzbot
still managed to trigger an underflow of the per-host bulk flow
counters, leading to an out of bounds memory access.
To avoid any such logic errors causing out of bounds memory accesses,
this commit factors out all accesses to the per-host bulk flow counters
to a series of helpers that perform bounds-checking before any
increments and decrements. This also has the benefit of improving
readability by moving the conditional checks for the flow mode into
these helpers, instead of having them spread out throughout the
code (which was the cause of the original logic error).
As part of this change, the flow quantum calculation is consolidated
into a helper function, which means that the dithering applied to the
ost load scaling is now applied both in the DRR rotation and when a
sparse flow's quantum is first initiated. The only user-visible effect
of this is that the maximum packet size that can be sent while a flow
stays sparse will now vary with +/- one byte in some cases. This should
not make a noticeable difference in practice, and thus it's not worth
complicating the code to preserve the old behaviour.

We've noticed that NFS can hang when using RPC over TLS on an unstable
connection, and investigation shows that the RPC layer is stuck in a tight
loop attempting to transmit, but forever getting -EBADMSG back from the
underlying network. The loop begins when tcp_sendmsg_locked() returns
-EPIPE to tls_tx_records(), but that error is converted to -EBADMSG when
calling the socket's error reporting handler.
Instead of converting errors from tcp_sendmsg_locked(), let's pass them
along in this path. The RPC layer handles -EPIPE by reconnecting the
transport, which prevents the endless attempts to transmit on a broken
connection.

ptp4l application reports too high offset when ran on E823 device
with a 100GB/s link. Those values cannot go under 100ns, like in a
working case when using 100 GB/s cable.
This is due to incorrect frequency settings on the PHY clocks for
100 GB/s speed. Changes are introduced to align with the internal
hardware documentation, and correctly initialize frequency in PHY
clocks with the frequency values that are in our HW spec.
To reproduce the issue run ptp4l as a Time Receiver on E823 device,
and observe the offset, which will never approach values seen
in the PTP working case.

expected offset to point to SNAP header (OID:PID), causing packet to

dropped, but doesn't fix the problem which is that LLC and SNAP should
not use transport_header offset.

On Chromebooks based on Mediatek MT8195 or MT8188, the audio frontend
(AFE) is limited to accessing a very small window (1 MiB) of memory,
which is described as a reserved memory region in the device tree.
On these two platforms, the maximum buffer size is given as 512 KiB.
The MediaTek common code uses the same value for preallocations. This
means that only the first two PCM substreams get preallocations, and
then the whole space is exhausted, barring any other substreams from
working. Since the substreams used are not always the first two, this
means audio won't work correctly.
This is observed on the MT8188 Geralt Chromebooks, on which the
"mediatek,dai-link" property was dropped when it was upstreamed. That
property causes the driver to only register the PCM substreams listed
in the property, and in the order given.
Instead of trying to compute an optimal value and figuring out which
streams are used, simply disable preallocation. The PCM buffers are
managed by the core and are allocated and released on the fly. There
should be no impact to any of the other MediaTek platforms.

dm_array_cursor_skip() seeks to the target position by loading array
blocks iteratively until the specified number of entries to skip is
reached. When seeking across block boundaries, it uses
dm_array_cursor_next() to step into the next block.
dm_array_cursor_skip() must first move the cursor index to the end
of the current block; otherwise, the cursor position could incorrectly
remain in the same block, causing the actual number of skipped entries
to be much smaller than expected.
This bug affects cache resizing in v2 metadata and could lead to data
loss if the fast device is shrunk during the first-time resume. For
example:
1. create a cache metadata consists of 32768 blocks, with a dirty block
assigned to the second bitmap block. cache_restore v1.0 is required.
cat <<EOF >> cmeta.xml
<superblock uuid="" block_size="64" nr_cache_blocks="32768" \

</mappings>
</superblock>
EOF
dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
cache_restore -i cmeta.xml -o /dev/mapper/cmeta --metadata-version=2
2. bring up the cache while attempt to discard all the blocks belonging
to the second bitmap block (block# 32576 to 32767). The last command
is expected to fail, but it actually succeeds.
dmsetup create cdata --table "0 2084864 linear /dev/sdc 8192"

This fix can be verified using the "array_cursor/iterate/empty" test
in dm-unit:
dm-unit run /pdata/array_cursor/iterate/empty --kernel-dir <KERNEL_DIR>

[ Upstream commit a0851ea9cd555c333795b85ddd908898b937c4e1 ]
When committing transaction in jbd2_journal_commit_transaction(), the
disk caches for the filesystem device should be flushed before updating
the journal tail sequence. However, this step is missed if the journal
is not located on the filesystem device. As a result, the filesystem may
become inconsistent following a power failure or system crash. Fix it by
ensuring that the filesystem device is flushed appropriately.

Commit '6a3afb6ac6df ("jbd2: increase the journal IO's priority")'
increases the priority of journal I/O by marking I/O with the
JBD2_JOURNAL_REQ_FLAGS. However, that commit missed the revoke buffers,
so also addresses that kind of I/Os.

commit 550f7ca98ee028a606aa75705a7e77b1bd11720f upstream.
If the full path to be built by ceph_mdsc_build_path() happens to be
longer than PATH_MAX, then this function will enter an endless (retry)
loop, effectively blocking the whole task. Most of the machine
becomes unusable, making this a very simple and effective DoS
vulnerability.
I cannot imagine why this retry was ever implemented, but it seems
rather useless and harmful to me. Let's remove it and fail with
ENAMETOOLONG instead.

This is a pre-requisite for the backport of commit 74363ec674cb ("zram:
fix uninitialized ZRAM not releasing backing device"), which has been
implemented differently in commit 7ac07a26de ("zram: preparation for
multi-zcomp support") upstream.
We only need to ensure that zcomp_destroy is not called with a NULL
comp, so add this check as the other commit cannot be backported easily.
