commit dc23806a7c upstream.
Currently, driver_match_device() is called from three sites. One site
(__device_attach_driver) holds device_lock(dev), but the other two
(bind_store and __driver_attach) do not. This inconsistency means that
bus match() callbacks are not guaranteed to be called with the lock
held.
Fix this by introducing driver_match_device_locked(), which guarantees
holding the device lock using a scoped guard. Replace the unlocked calls
in bind_store() and __driver_attach() with this new helper. Also add a
lock assertion to driver_match_device() to enforce this guarantee.
This consistency also fixes a known race condition. The driver_override
implementation relies on the device_lock, so the missing lock led to the
use-after-free (UAF) reported in Bugzilla for buses using this field.
Stress testing the two newly locked paths for 24 hours with
CONFIG_PROVE_LOCKING and CONFIG_LOCKDEP enabled showed no UAF recurrence
and no lockdep warnings.

commit cf74fcdc43 upstream.
With smbdirect_send_batch processing we likely have requests without
IB_SEND_SIGNALED, which will be destroyed in the final request
that has IB_SEND_SIGNALED set.
If the connection is broken all requests are signaled
even without explicit IB_SEND_SIGNALED.

The server has similar logic and it makes sure that
request->wr is used instead of a stack struct ib_send_wr send_wr.
This makes sure send_done can see request->wr.send_flags
as the next commit will check for IB_SEND_SIGNALED

commit 93ac432274 upstream.
When we are about to use the last send credit that was
granted to us by the peer, we need to wait until
we are ourself able to grant at least one credit
to the peer. Otherwise it might not be possible
for the peer to grant more credits.
The following sections in MS-SMBD are related to this:
3.1.5.1 Sending Upper Layer Messages
...
If Connection.SendCredits is 1 and the CreditsGranted field of the
message is 0, stop processing.
...
3.1.5.9 Managing Credits Prior to Sending
...
If Connection.ReceiveCredits is zero, or if Connection.SendCredits is
one and the Connection.SendQueue is not empty, the sender MUST allocate
and post at least one receive of size Connection.MaxReceiveSize and MUST
increment Connection.ReceiveCredits by the number allocated and posted.
If no receives are posted, the processing MUST return a value of zero to
indicate to the caller that no Send message can be currently performed.
...
This is a similar logic as we have in the server.

It turns out that our code will corrupt the stream of
reassabled data transfer messages when we trigger an
immendiate (empty) send.
In order to fix this we'll have a single 'batch' credit per

as much messages until remaining_length reaches 0, then
the batch credit it given back and the next logical send can
happen.

The logic off managing recv credits by counting posted recv_io and

That's because the peer might already consumed a credit,
but between receiving the incoming recv at the hardware
and processing the completion in the 'recv_done' functions
we likely have a window where we grant credits, which
don't really exist.
So we better have a decicated counter for the
available credits, which will be incremented
when we posted new recv buffers and drained when
we grant the credits to the peer.

commit 010eb01ce2 upstream.
The problem occurs when a signed request fails smb2 signature verification
check. In __process_request(), if check_sign_req() returns an error,
set_smb2_rsp_status(work, STATUS_ACCESS_DENIED) is called.
set_smb2_rsp_status() set work->next_smb2_rcv_hdr_off as zero. By resetting
next_smb2_rcv_hdr_off to zero, the pointer to the next command in the chain
is lost. Consequently, is_chained_smb2_message() continues to point to
the same request header instead of advancing. If the header's NextCommand
field is non-zero, the function returns true, causing __handle_ksmbd_work()
to repeatedly process the same failed request in an infinite loop.
This results in the kernel log being flooded with "bad smb2 signature"
messages and high CPU usage.
This patch fixes the issue by changing the return value from
SERVER_HANDLER_CONTINUE to SERVER_HANDLER_ABORT. This ensures that
the processing loop terminates immediately rather than attempting to
continue from an invalidated offset.

commit ec306600d5 upstream.
is_open, has_lease and on_list are stored in the same bitfield byte in
struct cached_fid but are updated in different code paths that may run
concurrently. Bitfield assignments generate byte read–modify–write
operations (e.g. `orb $mask, addr` on x86_64), so updating one flag can
restore stale values of the others.
A possible interleaving is:
CPU1: load old byte (has_lease=1, on_list=1)
CPU2: clear both flags (store 0)
CPU1: RMW store (old | IS_OPEN) -> reintroduces cleared bits
To avoid this class of races, convert these flags to separate bool
fields.

For tasks that used io_uring for file I/O and then stop using io_uring,
this can leave an iou-wrk-* thread behind even after all io_uring
instances are gone. This is unnecessary overhead and also gets in the
way of process checkpoint/restore.

they become idle, and provide io_wq_set_exit_on_idle() to toggle it.

Fedora QA reported the following panic:
BUG: unable to handle page fault for address: 0000000040003e54
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page
Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS edk2-20251119-3.fc43 11/19/2025
RIP: 0010:vmware_hypercall4.constprop.0+0x52/0x90
..
Call Trace:
vmmouse_report_events+0x13e/0x1b0
psmouse_handle_byte+0x15/0x60
ps2_interrupt+0x8a/0xd0
...
because the QEMU VMware mouse emulation is buggy, and clears the top 32
bits of %rdi that the kernel kept a pointer in.
The QEMU vmmouse driver saves and restores the register state in a
"uint32_t data[6];" and as a result restores the state with the high
bits all cleared.
RDI originally contained the value of a valid kernel stack address
(0xff5eeb3240003e54). After the vmware hypercall it now contains
0x40003e54, and we get a page fault as a result when it is dereferenced.
The proper fix would be in QEMU, but this works around the issue in the
kernel to keep old setups working, when old kernels had not happened to
keep any state in %rdi over the hypercall.
In theory this same issue exists for all the hypercalls in the vmmouse
driver; in practice it has only been seen with vmware_hypercall3() and
vmware_hypercall4(). For now, just mark RDI/RSI as clobbered for those
two calls. This should have a minimal effect on code generation overall
as it should be rare for the compiler to want to make RDI/RSI live
across hypercalls.

- Fix event format field alignments for 32 bit architectures
The fields in the event format files are used to parse the raw binary
buffer data by applications. If they are incorrect, then the application
produces garbage.
On 32 bit architectures, the function graph 64bit calltime and rettime
were off by 4bytes. That's because the actual fields are in a packed
structure but the macros used by the ftrace events did not mark them as
packed, and instead, gave them their natural alignment which made their
offsets off by 4 bytes.
There are macros to have a packed field within an embedded structure of
an event, but there's no macro for normal fields within a packed
structure of the event. The macro __field_packed() was used for the
packed embedded structure field. Rename that to __field_desc_pcaked() (to
match the non-packed embedded field macro __field_desc()), and make
__field_packed() for fields that are in a packed event structure (which
matches the unpacked __field() macro).
Switch the calltime and rettime fields of the function graph event to use
the new __field_packed() and this makes the offsets correct.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rmk/linux
Pull ARM fix from Russell King:
"Just one fix for memset64() on big endian 32-bit ARM systems"
* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rmk/linux:
ARM: 9468/1: fix memset64() on big-endian
The PASID_FLAG_PAGE_SNOOP and PASID_FLAG_PWSNP constants are identical.
This will cause the pasid code to always set both or neither of the
PGSNP and PWSNP bits in PASID table entries. However, PWSNP is a
reserved bit if SMPWC is not set in the IOMMU's extended capability
register, even if SC is supported.
This has resulted in DMAR errors when testing the iommufd code on an
Arrow Lake platform. With this patch, those errors disappear and the
PASID table entries look correct.
Fixes: 101a285411 ("iommu/vt-d: Follow PT_FEAT_DMA_INCOHERENT into the PASID entry")

"The usual xe/amdgpu selection, and a couple of misc changes for
gma500, mgag200 and bridge. There is a nouveau revert, and also a set

it's mostly just refactoring to pass an extra bit down the nouveau
abstractions to the firmware command.
