commit 36991c1ccd upstream.
A use-after-free is possible if one thread destroys the file
via __ksmbd_close_fd while another thread holds a reference to
it. The existing checks on fp->refcount are not sufficient to
prevent this.
The fix takes ft->lock around the section which removes the
file from the file table. This prevents two threads acquiring the
same file pointer via __close_file_table_ids, as well as the other
functions which retrieve a file from the IDR and which already use
this same lock.

commit 0ca6df4f40 upstream.
ksmbd_vfs_stream_write() did not validate whether the write offset
(*pos) was within the bounds of the existing stream data length (v_len).
If *pos was greater than or equal to v_len, this could lead to an
out-of-bounds memory write.
This patch adds a check to ensure *pos is less than v_len before
proceeding. If the condition fails, -EINVAL is returned.

commit 037ada7a31 upstream.
If a driver is removed, the driver framework invokes the driver's
remove callback. A CAN driver's remove function calls
unregister_candev(), which calls net_device_ops::ndo_stop further down
in the call stack for interfaces which are in the "up" state.
The removal of the module causes a warning, as can_rx_offload_del()
deletes the NAPI, while it is still active, because the interface is
still up.
To fix the warning, first unregister the network interface, which
calls net_device_ops::ndo_stop, which disables the NAPI, and then call
can_rx_offload_del().

was changed from a direct return to a goto to the unlock and
pci_dev_put() section. The change however left the existing pci_dev_put()
untouched resulting in a doubple put. This can subsequently cause a use
after free if the struct pci_dev is released in an unexpected state.
Fix this by removing the extra pci_dev_put().

commit c1d9dac0db upstream.
The vfio-pci huge_fault handler doesn't make any attempt to insert a
mapping containing the faulting address, it only inserts mappings if the
faulting address and resulting pfn are aligned. This works in a lot of
cases, particularly in conjunction with QEMU where DMA mappings linearly
fault the mmap. However, there are configurations where we don't get
that linear faulting and pages are faulted on-demand.
The scenario reported in the bug below is such a case, where the physical
address width of the CPU is greater than that of the IOMMU, resulting in a
VM where guest firmware has mapped device MMIO beyond the address width of
the IOMMU. In this configuration, the MMIO is faulted on demand and
tracing indicates that occasionally the faults generate a VM_FAULT_OOM.
Given the use case, this results in a "error: kvm run failed Bad address",
killing the VM.
The host is not under memory pressure in this test, therefore it's
suspected that VM_FAULT_OOM is actually the result of a NULL return from
__pte_offset_map_lock() in the get_locked_pte() path from insert_pfn().
This suggests a potential race inserting a pte concurrent to a pmd, and
maybe indicates some deficiency in the mm layer properly handling such a
case.
Nevertheless, Peter noted the inconsistency of vfio-pci's huge_fault
handler where our mapping granularity depends on the alignment of the
faulting address relative to the order rather than aligning the faulting
address to the order to more consistently insert huge mappings. This
change not only uses the page tables more consistently and efficiently, but
as any fault to an aligned page results in the same mapping, the race
condition suspected in the VM_FAULT_OOM is avoided.

commit 8fb1dcbbcc upstream.
This reverts commit 7e06de7c83.
Commit 7e06de7c83 ("btrfs: canonicalize the device path before adding
it") tries to make btrfs to use "/dev/mapper/*" name first, then any
filename inside "/dev/" as the device path.
This is mostly fine when there is only the root namespace involved, but
when multiple namespace are involved, things can easily go wrong for the
d_path() usage.
As d_path() returns a file path that is namespace dependent, the
resulted string may not make any sense in another namespace.
Furthermore, the "/dev/" prefix checks itself is not reliable, one can
still make a valid initramfs without devtmpfs, and fill all needed
device nodes manually.
Overall the userspace has all its might to pass whatever device path for
mount, and we are not going to win the war trying to cover every corner
case.
So just revert that commit, and do no extra d_path() based file path
sanity check.

commit bbfe756dc3 upstream.
If bio_add_folio() fails (because it is full),
erofs_fileio_scan_folio() needs to submit the I/O request via
erofs_fileio_rq_submit() and allocate a new I/O request with an empty
`struct bio`. Then it retries the bio_add_folio() call.
However, at this point, erofs_onlinefolio_split() has already been
called which increments `folio->private`; the retry will call
erofs_onlinefolio_split() again, but there will never be a matching
erofs_onlinefolio_end() call. This leaves the folio locked forever
and all waiters will be stuck in folio_wait_bit_common().
This bug has been added by commit ce63cb62d7 ("erofs: support
unencoded inodes for fileio"), but was practically unreachable because
there was room for 256 folios in the `struct bio` - until commit
9f74ae8c9a ("erofs: shorten bvecs[] for file-backed mounts") which
reduced the array capacity to 16 folios.
It was now trivial to trigger the bug by manually invoking readahead
from userspace, e.g.:
posix_fadvise(fd, 0, st.st_size, POSIX_FADV_WILLNEED);
This should be fixed by invoking erofs_onlinefolio_split() only after
bio_add_folio() has succeeded. This is safe: asynchronous completions
invoking erofs_onlinefolio_end() will not unlock the folio because
erofs_fileio_scan_folio() is still holding a reference to be released
by erofs_onlinefolio_end() at the end.

Completion of the FFA_PARTITION_INFO_GET ABI transfers the ownership of

from the consumer back to the producer.
However, when we set the flag to just return the count of partitions
deployed in the system corresponding to the specified UUID while
invoking FFA_PARTITION_INFO_GET, the Rx buffer ownership shouldn't be
transferred to this driver. We must be able to skip transferring back
the ownership to the partition manager when we request just to get the
count of the partitions as the buffers are not acquired in this case.
Firmware may return FFA_RET_DENIED or other error for the ffa_rx_release()
in such cases.

Using device_find_child() to lookup the proper SCMI device to destroy
causes an unbalance in device refcount, since device_find_child() calls an
implicit get_device(): this, in turns, inhibits the call of the provided
release methods upon devices destruction.
As a consequence, one of the structures that is not freed properly upon
destruction is the internal struct device_private dev->p populated by the
drivers subsystem core.
KMemleak detects this situation since loading/unloding some SCMI driver
causes related devices to be created/destroyed without calling any
device_release method.

After the last job is destroyed, it proceeds to release the related context

the file_priv lock (#2) is taken first, and then the submitted_jobs
lock (#1) is obtained when a job is added to the submitted jobs list.

The fallback code in blk_mq_map_hw_queues is original from
blk_mq_pci_map_queues and was added to handle the case where
pci_irq_get_affinity will return NULL for !SMP configuration.
blk_mq_map_hw_queues replaces besides blk_mq_pci_map_queues also
blk_mq_virtio_map_queues which used to use blk_mq_map_queues for the
fallback.
It's possible to use blk_mq_map_queues for both cases though.
blk_mq_map_queues creates the same map as blk_mq_clear_mq_map for !SMP
that is CPU 0 will be mapped to hctx 0.
The WARN_ON_ONCE has to be dropped for virtio as the fallback is also
taken for certain configuration on default. Though there is still a
WARN_ON_ONCE check in lib/group_cpus.c:
WARN_ON(nr_present + nr_others < numgrps);
which will trigger if the caller tries to create more hardware queues
than CPUs. It tests the same as the WARN_ON_ONCE in
blk_mq_pci_map_queues did.

[ Upstream commit ee512922dd ]
In case the CMD_RTS got corrupted by interferences, the MSE102x
doesn't allow a retransmission of the command. Instead the Ethernet
frame must be shifted out of the SPI FIFO. Since the actual length is
unknown, assume the maximum possible value.
