[ Upstream commit 5191a8d3c2 ]
This patch modifies the implementation of debugfs:
When the user process stops unexpectedly, not all data of the file system
is read. In this case, the save_buf pointer is not released. When the
user process is called next time, save_buf is used to copy the cached
data to the user space. As a result, the queried data is stale.
To solve this problem, this patch implements .open() and .release() handler
for debugfs file_operations. moving allocation buffer and execution
of the cmd to the .open() handler and freeing in to the .release() handler.
Allocate separate buffer for each reader and associate the buffer
with the file pointer.
When different user read processes no longer share the buffer,
the stale data problem is fixed.

When a reset type that is not supported by the driver is input, a reset
pending flag bit of the HNAE3_NONE_RESET type is generated in
reset_pending. The driver does not have a mechanism to clear this type

complete. This patch provides a mechanism to clear the

hnae3_ae_ops.set_default_reset_request is verified.

[ Upstream commit b341ca51d2 ]
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.

[ Upstream commit bd2776e39c ]
When booting with a dock connected, the igc driver may get stuck for ~40
seconds if PCIe link is lost during initialization.
This happens because the driver access device after EECD register reads
return all F's, indicating failed reads. Consequently, hw->hw_addr is set
to NULL, which impacts subsequent rd32() reads. This leads to the driver
hanging in igc_get_hw_semaphore_i225(), as the invalid hw->hw_addr
prevents retrieving the expected value.
To address this, a validation check and a corresponding return value
catch is added for the EECD register read result. If all F's are
returned, indicating PCIe link loss, the driver will return -ENXIO
immediately. This avoids the 40-second hang and significantly improves
boot time when using a dock with an igc NIC.

[ Upstream commit 6c5b989116 ]
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.
Reproduction output:

DIM work will call the firmware to adjust the coalescing parameters on

message like this:

and cause unnecessary concern for the user. It is also possible to
modify the coalescing parameters of the wrong ring if the ring has
been re-allocated.
To prevent this, cancel DIM work right before freeing the RX rings.
We also have to add a check in NAPI poll to not schedule DIM if the
RX rings are shutting down. Check that the VNIC is active before we
schedule DIM. The VNIC is always disabled before we free the RX rings.

[CAUSE]
The reproducer is using a corrupted image where extent tree root is
corrupted, thus forcing to use "rescue=all,ro" mount option to mount the
image.
Then it triggered a scrub, but since scrub relies on extent tree to find
where the data/metadata extents are, scrub_find_fill_first_stripe()
relies on an non-empty extent root.
But unfortunately scrub_find_fill_first_stripe() doesn't really expect
an NULL pointer for extent root, it use extent_root to grab fs_info and
triggered a NULL pointer dereference.
[FIX]
Add an extra check for a valid extent root at the beginning of
scrub_find_fill_first_stripe().
The new error path is introduced by 42437a6386 ("btrfs: introduce
mount option rescue=ignorebadroots"), but that's pretty old, and later
commit b979547513 ("btrfs: scrub: introduce helper to find and fill
sector info for a scrub_stripe") changed how we do scrub.
So for kernels older than 6.6, the fix will need manual backport.

'firmware ready' does not timeout. Then driver would mistakenly believe
that the interaction has completed successfully.
It tends to happen with the use of custom firmware. Move the check for
'unknown command' out of the poll timeout for 'firmware ready'. And adjust
the debug log so that mailbox messages are always printed when commands
timeout.

When the net.ipv4.tcp_syncookies is zero, inet_csk_reqsk_queue_is_full()

802.2+LLC+SNAP frames received by napi_complete_done() with GRO and DSA
have skb->transport_header set two bytes short, or pointing 2 bytes
before network_header & skb->data. This was an issue as snap_rcv()
expected offset to point to SNAP header (OID:PID), causing packet to
be dropped.
A fix at llc_fixup_skb() (a024e377ef) resets transport_header for any
LLC consumers that may care about it, and stops SNAP packets from being
dropped, but doesn't fix the problem which is that LLC and SNAP should
not use transport_header offset.
Ths patch eliminates the use of transport_header offset for SNAP lookup
of OID:PID so that SNAP does not rely on the offset at all.
The offset is reset after pull for any SNAP packet consumers that may
(but shouldn't) use it.

[ Upstream commit 32c9c06adb ]
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.

[ Upstream commit c45beebfde ]
Dmitry Safonov reported that a WARN_ON() assertion can be trigered by
userspace when calling inotify_show_fdinfo() for an overlayfs watched
inode, whose dentry aliases were discarded with drop_caches.
The WARN_ON() assertion in inotify_show_fdinfo() was removed, because
it is possible for encoding file handle to fail for other reason, but
the impact of failing to encode an overlayfs file handle goes beyond
this assertion.
As shown in the LTP test case mentioned in the link below, failure to
encode an overlayfs file handle from a non-aliased inode also leads to
failure to report an fid with FAN_DELETE_SELF fanotify events.
As Dmitry notes in his analyzis of the problem, ovl_encode_fh() fails
if it cannot find an alias for the inode, but this failure can be fixed.
ovl_encode_fh() seldom uses the alias and in the case of non-decodable
file handles, as is often the case with fanotify fid info,
ovl_encode_fh() never needs to use the alias to encode a file handle.
Defer finding an alias until it is actually needed so ovl_encode_fh()
will not fail in the common case of FAN_DELETE_SELF fanotify events.

[ Upstream commit d0327c8243 ]
When the caching for a cookie is temporarily disabled (e.g. due to a DIO
write on that file), future copying to the cache for that file is disabled
until all fds open on that file are closed. However, if netfslib is using
the deprecated PG_private_2 method (such as is currently used by ceph), and
decides it wants to copy to the cache, netfs_advance_write() will just bail
at the first check seeing that the cache stream is unavailable, and
indicate that it dealt with all the content.
This means that we have no subrequests to provide notifications to drive
the state machine or even to pin the request and the request just gets
discarded, leaving the folios with PG_private_2 set.
Fix this by jumping directly to cancel the request if the cache is not
available. That way, we don't remove mark3 from the folio_queue list and
netfs_pgpriv2_cancel() will clean up the folios.
This was found by running the generic/013 xfstest against ceph with an
active cache and the "-o fsc" option passed to ceph. That would usually
hang

appropriately for copying to the cache (either with by being marked dirty
and having their private data set or by having PG_private_2 set) and then
unlocked, the folio_queue struct has the entry pointing to the folio
cleared. This presents a problem for netfs_pgpriv2_write_to_the_cache(),
which is used to write folios marked with PG_private_2 to the cache as it
expects to be able to trawl the folio_queue list thereafter to find the
relevant folios, leading to a hang.
Fix this by not clearing the folio_queue entry if we're going to do the

are written to the cache.

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.

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.

[ Upstream commit 51d20d1dac ]
During concurrent append writes to XFS filesystem, zero padding data
may appear in the file after power failure. This happens due to imprecise
disk size updates when handling write completion.
Consider this scenario with concurrent append writes same file:
Thread 1: Thread 2:
------------ -----------
write [A, A+B]
update inode size to A+B
submit I/O [A, A+BS]
write [A+B, A+B+C]
update inode size to A+B+C
<I/O completes, updates disk size to min(A+B+C, A+BS)>
<power failure>
After reboot:
1) with A+B+C < A+BS, the file has zero padding in range [A+B, A+B+C]
|< Block Size (BS) >|
|DDDDDDDDDDDDDDDD0000000000000000|
^ ^ ^
A A+B A+B+C
(EOF)
2) with A+B+C > A+BS, the file has zero padding in range [A+B, A+BS]
|< Block Size (BS) >|< Block Size (BS) >|
|DDDDDDDDDDDDDDDD0000000000000000|00000000000000000000000000000000|
^ ^ ^ ^
A A+B A+BS A+B+C
(EOF)
D = Valid Data
0 = Zero Padding
The issue stems from disk size being set to min(io_offset + io_size,
inode->i_size) at I/O completion. Since io_offset+io_size is block
size granularity, it may exceed the actual valid file data size. In
the case of concurrent append writes, inode->i_size may be larger
than the actual range of valid file data written to disk, leading to
inaccurate disk size updates.
This patch modifies the meaning of io_size to represent the size of
valid data within EOF in an ioend. If the ioend spans beyond i_size,
io_size will be trimmed to provide the file with more accurate size
information. This is particularly useful for on-disk size updates
at completion time.
After this change, ioends that span i_size will not grow or merge with
other ioends in concurrent scenarios. However, these cases that need
growth/merging rarely occur and it seems no noticeable performance impact.
Although rounding up io_size could enable ioend growth/merging in these
scenarios, we decided to keep the code simple after discussion [1].
Another benefit is that it makes the xfs_ioend_is_append() check more
accurate, which can reduce unnecessary end bio callbacks of xfs_end_bio()
in certain scenarios, such as repeated writes at the file tail without
extending the file size.

[ Upstream commit b44679c63e ]
This is a preparatory patch for fixing zero padding issues in concurrent
append write scenarios. In the following patches, we need to obtain
byte-granular writeback end position for io_size trimming after EOF
handling.
Due to concurrent writeback and truncate operations, inode size may
shrink. Resampling inode size would force writeback code to handle the
newly appeared post-EOF blocks, which is undesirable. As Dave
explained in [1]:
"Really, the issue is that writeback mappings have to be able to
handle the range being mapped suddenly appear to be beyond EOF.
This behaviour is a longstanding writeback constraint, and is what
iomap_writepage_handle_eof() is attempting to handle.
We handle this by only sampling i_size_read() whilst we have the
folio locked and can determine the action we should take with that
folio (i.e. nothing, partial zeroing, or skip altogether). Once
we've made the decision that the folio is within EOF and taken
action on it (i.e. moved the folio to writeback state), we cannot
then resample the inode size because a truncate may have started
and changed the inode size."
To avoid resampling inode size after EOF handling, we convert end_pos
to byte-granular writeback position and return it from EOF handling
function.
Since iomap_set_range_dirty() can handle unaligned lengths, this
conversion has no impact on it. However, iomap_find_dirty_range()
requires aligned start and end range to find dirty blocks within the
given range, so the end position needs to be rounded up when passed

[ Upstream commit 30dac24e14 ]
Most of the callers of wbc_account_cgroup_owner() are converting a folio
to page before calling the function. wbc_account_cgroup_owner() is
converting the page back to a folio to call mem_cgroup_css_from_folio().
Convert wbc_account_cgroup_owner() to take a folio instead of a page,
and convert all callers to pass a folio directly except f2fs.
Convert the page to folio for all the callers from f2fs as they were the
only callers calling wbc_account_cgroup_owner() with a page. As f2fs is
already in the process of converting to folios, these call sites might
also soon be calling wbc_account_cgroup_owner() with a folio directly in
the future.
No functional changes. Only compile tested.

[ Upstream commit a0851ea9cd ]
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 '6a3afb6ac6 ("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.
