[ Upstream commit 3f6bc9e3ab ]
Netfslib needs to be able to handle kernel-initiated asynchronous DIO that
is supplied with a bio_vec[] array. Currently, because of the async flag,
this gets passed to netfs_extract_user_iter() which throws a warning and
fails because it only handles IOVEC and UBUF iterators. This can be
triggered through a combination of cifs and a loopback blockdev with
something like:
mount //my/cifs/share /foo
dd if=/dev/zero of=/foo/m0 bs=4K count=1K
losetup --sector-size 4096 --direct-io=on /dev/loop2046 /foo/m0
echo hello >/dev/loop2046
This causes the following to appear in syslog:
WARNING: CPU: 2 PID: 109 at fs/netfs/iterator.c:50 netfs_extract_user_iter+0x170/0x250 [netfs]
and the write to fail.
Fix this by removing the check in netfs_unbuffered_write_iter_locked() that
causes async kernel DIO writes to be handled as userspace writes. Note
that this change relies on the kernel caller maintaining the existence of
the bio_vec array (or kvec[] or folio_queue) until the op is complete.

If GuC fails to load, the driver wedges, but in the process it tries to
do stuff that may not be initialized yet. This moves the
xe_gt_tlb_invalidation_init() to be done earlier: as its own doc says,
it's a software-only initialization and should had been named with the
_early() suffix.
Move it to be called by xe_gt_init_early(), so the locks and seqno are
initialized, avoiding a NULL ptr deref when wedging:

ret_from_exception symbol address and the stacktrace code checked 'pc' to

handle_exception(). Since there are multiple call site to C code in the

to be in that range.

[ Upstream commit f754f27e98 ]
In sparse vmemmap model, the virtual address of vmemmap is calculated as:
((struct page *)VMEMMAP_START - (phys_ram_base >> PAGE_SHIFT)).
And the struct page's va can be calculated with an offset:
(vmemmap + (pfn)).
However, when initializing struct pages, kernel actually starts from the
first page from the same section that phys_ram_base belongs to. If the
first page's physical address is not (phys_ram_base >> PAGE_SHIFT), then
we get an va below VMEMMAP_START when calculating va for it's struct page.
For example, if phys_ram_base starts from 0x82000000 with pfn 0x82000, the
first page in the same section is actually pfn 0x80000. During
init_unavailable_range(), we will initialize struct page for pfn 0x80000
with virtual address ((struct page *)VMEMMAP_START - 0x2000), which is
below VMEMMAP_START as well as PCI_IO_END.
This commit fixes this bug by introducing a new variable
'vmemmap_start_pfn' which is aligned with memory section size and using
it to calculate vmemmap address instead of phys_ram_base.

The 'np' device_node is initialized via of_cpu_device_node_get(), which

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

However, the DNS limits the maximum lookup length and, by extension, the

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

[ Upstream commit 737d4d91d3 ]
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.

[ Upstream commit 2d2d4f60ed ]
We found a timeout problem with the pldm command on our system. The
reason is that the MCTP-I3C driver has a race condition when receiving
multiple-packet messages in multi-thread, resulting in a wrong packet
order problem.
We identified this problem by adding a debug message to the
mctp_i3c_read function.
According to the MCTP spec, a multiple-packet message must be composed
in sequence, and if there is a wrong sequence, the whole message will be
discarded and wait for the next SOM.
For example, SOM → Pkt Seq #2 → Pkt Seq #1 → Pkt Seq #3 → EOM.
Therefore, we try to solve this problem by adding a mutex to the
mctp_i3c_read function. Before the modification, when a command
requesting a multiple-packet message response is sent consecutively, an
error usually occurs within 100 loops. After the mutex, it can go
through 40000 loops without any error, and it seems to run well.

[ Upstream commit 7997ddd46c ]
The TQP BAR space is divided into two segments. TQPs 0-1023 and TQPs
1024-1279 are in different BAR space addresses. However,
hclge_fetch_pf_reg does not distinguish the tqp space information when
reading the tqp space information. When the number of TQPs is greater
than 1024, access bar space overwriting occurs.
The problem of different segments has been considered during the
initialization of tqp.io_base. Therefore, tqp.io_base is directly used
when the queue is read in hclge_fetch_pf_reg.

[ 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.

[ 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.

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

This is due to incorrect frequency settings on the PHY clocks for
