Fragment reassembly reuses the skb from the highest-numbered buffered
fragment as the merged packet. When that fragment was received on a hard
interface which is deleted before the chain completes, the merged skb can
re-enter the receive path with a stale skb->dev and skb_iif.
batadv_batman_skb_recv() passes such merged packets through the normal
receive handlers again. DAT and bridge loop avoidance both derive the ARP
header length from skb->dev, so they can dereference the freed net_device
before the packet reaches the local mesh interface.
Refresh the receive device metadata from the current receive device before
running the packet handlers. This keeps internally reinjected merged
fragments consistent with the normal receive path after hard interface
teardown.

The kernel documentation for batadv_send_skb_unicast() states that only the
return values NET_XMIT_DROP and NET_XMIT_SUCCESS are valid. Functions like
batadv_dat_snoop_incoming_arp_request() are only checking if the return is
not NET_XMIT_DROP to check if send was successful or not. Negative values
were therefore also handled as success.
Similar functions are not returning the batadv_send_skb_to_orig() return
value directly but are checking if it is a direct success and only then
marking the return as such. This must also be adopted for
batadv_send_skb_unicast().
The callers of this function are mostly not affected. Only packet counting
in batadv_dat_snoop_incoming_arp_request() will now work as expected in
case of a negative return value from batadv_send_skb_to_orig().

fcp_ioctl_init() allocates its response buffer with kmalloc() and copies
the whole buffer back to userspace:
buf_size = init.step0_resp_size + init.step2_resp_size;
void *resp __free(kfree) =
kmalloc(buf_size, GFP_KERNEL);
...
if (copy_to_user(arg->resp, resp, buf_size))
return -EFAULT;
Nothing clears the buffer, and the only writer of its leading
step0_resp_size bytes is the step-0 control transfer:
err = snd_usb_ctl_msg(dev, usb_rcvctrlpipe(dev, 0),
FCP_USB_REQ_STEP0,
USB_RECIP_INTERFACE | USB_TYPE_CLASS | USB_DIR_IN,
0, private->bInterfaceNumber,
step0_resp, private->step0_resp_size);
if (err < 0)
return err;
usb_fill_control_urb() does not set URB_SHORT_NOT_OK, so a short or
zero-length data stage completes with status 0 and snd_usb_ctl_msg()
returns a small actual_length. The only check is err < 0, so a short
transfer is accepted as success.
snd_usb_ctl_msg() copies the full size back unconditionally:
buf = kmemdup(data, size, GFP_KERNEL);
...
memcpy(data, buf, size);
Bytes the device never wrote are therefore restored into resp unchanged
and copied to userspace. step0_resp_size and step2_resp_size are each
validated only to 1..255, so the caller also picks the slab cache, from
kmalloc-8 up to kmalloc-512.
On 7.2.0-rc5 (arm64), device answering step 0 with a zero-length data
stage, s0 = s2 = 255:
# init_on_alloc off, no spray
step0 window [0,255): nonzero=94/255
000: 00 80 60 06 00 00 ff ff 18 00 00 00 57 01 ea 01
010: 08 78 22 13 00 00 ff ff a8 c4 5f 80 00 80 ff ff
# same kernel, kmalloc-512 pre-seeded with an 8-byte tag
step0 window [0,255): nonzero=219/255 tagbytes=232
# identical run, init_on_alloc=1
step0 window [0,255): nonzero=0/255 tagbytes=0
# all three runs
step2 window [255,510): device words matched=62/62
a8 c4 5f 80 00 80 ff ff is the little-endian kernel text address
ffff8000805fc4a8. The step-2 window is unaffected, so the disclosure is
exactly the step-0 region.
Zero the buffer, and require the step-0 transfer to deliver the full
step0_resp_size bytes so a short data stage is reported as an error.

snd_us428ctls_vm_fault() turns the faulting page offset into a kernel
address with no bound of any kind:
offset = vmf->pgoff << PAGE_SHIFT;
vaddr = (char *)(...)->us428ctls_sharedmem + offset;
page = virt_to_page(vaddr);
get_page(page);
vmf->page = page;
return 0;
snd_us428ctls_mmap() checks only the length of the mapping, never the
offset, and us428ctls_sharedmem is a single page from
alloc_pages_exact(). For a character device file_mmap_size_max()
returns ULONG_MAX, so the mm layer imposes no ceiling either. Every page
offset above zero resolves to a struct page outside the object, and the
handler installs it into the caller's address space read-write; the vma
is not marked read-only.
The caller picks the page frame with a single mmap() argument and gets
read-write access to a page of kernel memory it does not own; an offset
that lands in an unpopulated vmemmap region oopses instead.
A process that can open the hwdep node of an attached US-X2Y reaches
this after loading the FPGA image through the same node; no capability
check is involved.
On 7.2.0-rc5 (arm64), mmap() with a large offset:
Unable to handle kernel paging request at virtual address fffffdffc45d5ac8

data_ep_set_params() sizes each URB transfer buffer before it adds the
Format Type II transfer delimiter:
u->packets = urb_packs;
u->buffer_size = maxsize * u->packets;
if (fmt->fmt_type == UAC_FORMAT_TYPE_II)
u->packets++; /* for transfer delimiter */
u->urb = usb_alloc_urb(u->packets, GFP_KERNEL);
buffer_size is computed from the pre-increment packet count and never
recomputed, so for a Type II endpoint the buffer is one packet short of
the packet count the URB is built with.
prepare_inbound_urb() then lays out one iso frame per packet and never
consults buffer_size:
offs = 0;
for (i = 0; i < urb_ctx->packets; i++) {
urb->iso_frame_desc[i].offset = offs;
urb->iso_frame_desc[i].length = ep->curpacksize;
offs += ep->curpacksize;
}
urb->transfer_buffer_length = offs;
urb->number_of_packets = urb_ctx->packets;
The last descriptor therefore points one packet past the end of the
transfer buffer, where the host controller writes device data on every
inbound transfer. prepare_silent_urb() and prepare_playback_urb() bound
their fill loops by ctx->buffer_size, so only capture is affected.
fmt_type comes from the device's audio streaming descriptors, so any
device advertising a Type II capture format hits this once userspace sets
hw_params on the stream.

bcd2000_free_usb_related_resources() frees both URBs and leaves the
pointers behind:
usb_kill_urb(bcd2k->midi_out_urb);
usb_kill_urb(bcd2k->midi_in_urb);
usb_free_urb(bcd2k->midi_out_urb);
usb_free_urb(bcd2k->midi_in_urb);
The rawmidi device outlives that call. A substream that is still open
when the device is unplugged reaches bcd2000_midi_send() from the
trigger path on close. That function writes to the freed URB and then
hands it to the USB core:
bcd2k->midi_out_urb->transfer_buffer_length = BUFSIZE;
...
ret = usb_submit_urb(bcd2k->midi_out_urb, GFP_ATOMIC);
usb_kill_urb() does not stop a later submission either, so a submit that
races the disconnect can requeue the URB after it has been reaped.
midi_in_urb is exposed the same way: bcd2000_input_complete() resubmits
it from the completion handler.

Clear both pointers after freeing and test them on the paths that can

for a running completion handler and rejects any later submission, so
after it returns the input path is quiesced and only the rawmidi trigger

usb6fire_comm_receiver_handler() forwards a MIDI event using a length
byte the device supplies, with no bound and no check that the transfer
delivered that many bytes:
if (!urb->status) {
if (rt->receiver_buffer[0] == 0x10) /* midi in event */
if (midi_rt)
midi_rt->in_received(midi_rt,
rt->receiver_buffer + 2,
rt->receiver_buffer[1]);
}
receiver_buffer is a 64-byte kzalloc() buffer (COMM_RECEIVER_BUFSIZE), so
only 62 bytes follow the two-byte header. receiver_buffer[1] is a u8 the
device chooses, so a device that answers with 0x10 and a length of 0xFF
makes snd_rawmidi_receive() read 255 bytes starting two bytes into a
64-byte object. The bytes past the buffer are handed to userspace
through the rawmidi read path.
urb->actual_length is not consulted either, so a short transfer leaves
both the type byte and the length byte at their previous values and the
handler acts on stale data.
The receiver URB is submitted from usb6fire_comm_init() at probe, so the
read happens on plug with no user action; forwarding to userspace also
needs a MIDI input substream open, since usb6fire_midi_in_received()
only calls snd_rawmidi_receive() when rt->in is set.

The fixed-size components field in SNDRV_CTL_IOCTL_CARD_INFO can be too
small on systems with many audio devices.
Keep the existing struct snd_ctl_card_info ABI intact and add a new
ioctl SNDRV_CTL_IOCTL_CARD_BYTES that carries a variable-length payload
selected by a type discriminator. The first defined type
SND_CTL_CARD_BTYPE_COMPONENTS returns the full components string. The
ioctl is designed to be reused for other variable-length card payloads
in the future.
The user-space caller may set data_allocated == 0 (or data == NULL) to
query the required length; otherwise the kernel copies the payload into
the user buffer and writes back the actual length in data_len.
When the legacy components field in struct snd_ctl_card_info is
truncated, '>' is written just before the NUL terminator to signal to
user-space that the full string is available via the new ioctl.
card->components is now dynamically allocated and grown in 32 byte
increments via krealloc(), capped at 512 bytes.

`FbLayout` is currently used for both pre and post FSP architectures. It
contains ranges for each region of framebuffer, but on post FSP
architectures, only the size is actually used. The region locations are
decided by ACR, which runs as part of the GSP-FMC, not by the driver.
The driver only provides the sizes. So, for post FSP architectures
`FbLayout` contains essentially guesses for the offsets. Instead, make
separate types so that we only store the information that's actually
needed, rather than keeping around offsets that may not be correct.

Changing the input (diagnostic report type) mid-stream changes the
report size. Since V4L2 buffers are allocated based on the size at
stream start, changing the input while streaming could lead to a
heap buffer overflow if the new size is larger than the allocated
buffers.
Prevent this by blocking VIDIOC_S_INPUT with -EBUSY if the V4L2 queue
is busy (streaming).

rmi_f54_work() reads a diagnostics report from the device into
f54->report_data, sizing the transfer with rmi_f54_get_report_size():
report_size = rmi_f54_get_report_size(f54);
...
for (i = 0; i < report_size; i += F54_REPORT_DATA_SIZE) {
int size = min(F54_REPORT_DATA_SIZE, report_size - i);
...
rmi_read_block(.., f54->report_data + i, size);
}
report_data is allocated once at probe from F54's own electrode counts
(array3_size(f54->num_tx_electrodes, f54->num_rx_electrodes, sizeof(u16))),
but rmi_f54_get_report_size() computes the size from
drv_data->num_*_electrodes when those are set, i.e. from the F55
function's electrode counts. Both counts come straight from device
queries (F54 and F55 each report up to 255 electrodes) and nothing
constrains the F55 counts to the F54 ones.
A malicious or malfunctioning RMI4 device that reports larger F55
electrode counts than its F54 counts makes report_size exceed the
allocation, so the read loop writes past report_data (and the V4L2
dequeue memcpy() then reads past it). On conforming hardware the F55
configured electrodes are a subset of the F54 physical electrodes, so
report_size never exceeds the buffer and well-behaved devices are
unaffected.
Record the allocation size and reject a report that does not fit,
mirroring the existing zero-size check.

In rmi_f54_work(), if an error occurs during report request or command
verification, the code jumped directly to the 'error' label, bypassing
the 'abort' label where f54->report_size was normally zeroed out.
This left f54->report_size containing its previous successful payload
size. If a user then altered the V4L2 format to a smaller size, and a
subsequent run failed, rmi_f54_buffer_queue() would copy the stale,
larger payload size into the shrunken V4L2 buffer, causing a heap
buffer overflow.
Fix this by merging the 'abort' and 'error' labels into a single 'out'
exit path, and ensuring that f54->report_size is always set to 0 on
failure by checking for error and zeroing the local report_size first.

During F55 sensor detection, the transmitter (TX) electrode count was
incorrectly assigned the value of the receiver (RX) electrode count
due to copy-paste typos.
This incorrect value was then propagated to the driver data and used
by F54 to determine the diagnostics report size. On devices with more
RX than TX electrodes, this inflated the perceived TX count, leading
to incorrect report size calculations and potential out-of-bounds
buffer accesses.
Fix the typos by correctly assigning the TX electrode counts.

Using interrupts and scheduling workers increase latency so latency
critical applications may want to avoid that. Make this possible in
USB4STREAM by adding a new ConfigFS attribute: busy_poll that, when
activated switches the rings to polling mode. The cost for lower latency
is that this burns more CPU cycles and things like poll(2) cannot be
used.

For some use-cases it does make sense to poll the rings directly instead
of relying on the interrupt. For this reason add a new flag RING_FLAG_NO_INTERRUPT
that can be used to allocate ring in polled mode.

For read_iter/write_iter() it is also possible to pass IOCB_NOWAIT with
the kiocb to indicate non-blocking read/write. For instance io_uring
does this. So take this into account on read and write paths.

Since copy_page_{to|from}_iter() advances the iterator and makes
iov_iter_count() reflect the remaining bytes, subtracting nbytes from it
makes it count it twice resulting in possible short reads/writes on a
read/write spanning multiple frames.
Fix this by using iov_iter_count() directly.

In tbstream_dev_alloc_tx() if copying data from iterator fails we leave
the consumer pointer as is wasting one entry in the ring. Fix this by
restoring the consumer back in case of failure.

The QMP PHY expects the vdda-phy supply to be around 0.88V and the
vdda-pll supply to be 1.2V. But these two supplies are swapped for the
USB QMP PHYs on these boards, feeding 1.2V to vdda-phy and 0.88V to
vdda-pll.
Fix it by swapping the two supplies back.
