Endpoints with a maxpacket length of 0 are probably useless. They
can't transfer any data, and it's not at all unlikely that a UDC will
crash or hang when trying to handle a non-zero-length usb_request for
such an endpoint. Indeed, dummy-hcd gets a divide error when trying
to calculate the remainder of a transfer length by the maxpacket
value, as discovered by the syzbot fuzzer.
Currently the gadget core does not check for endpoints having a
maxpacket value of 0. This patch adds a check to usb_ep_enable(),
preventing such endpoints from being used.
As far as I know, none of the gadget drivers in the kernel tries to
create an endpoint with maxpacket = 0, but until now there has been
nothing to prevent userspace programs under gadgetfs or configfs from
doing it.

Commit 3ae62a4209 ("UAS: fix alignment of scatter/gather segments"),
copying a similar commit for usb-storage, attempted to solve a problem
involving scatter-gather I/O and USB/IP by setting the
virt_boundary_mask for mass-storage devices.
However, it now turns out that the analogous change in usb-storage
interacted badly with commit 09324d32d2 ("block: force an unlimited
segment size on queues with a virt boundary"), which was added later.
A typical error message is:
ehci-pci 0000:00:13.2: swiotlb buffer is full (sz: 327680 bytes),
total 32768 (slots), used 97 (slots)
There is no longer any reason to keep the virt_boundary_mask setting
in the uas driver. It was needed in the first place only for
handling devices with a block size smaller than the maxpacket size and
where the host controller was not capable of fully general
scatter-gather operation (that is, able to merge two SG segments into
a single USB packet). But:
High-speed or slower connections never use a bulk maxpacket
value larger than 512;
The SCSI layer does not handle block devices with a block size
smaller than 512 bytes;
All the host controllers capable of SuperSpeed operation can
handle fully general SG;
Since commit ea44d19076 ("usbip: Implement SG support to
vhci-hcd and stub driver") was merged, the USB/IP driver can
also handle SG.
Therefore all supported device/controller combinations should be okay
with no need for any special virt_boundary_mask. So in order to head
off potential problems similar to those affecting usb-storage, this
patch reverts commit 3ae62a4209.

iso_buffer should be set to NULL after use and free in the while loop.
In the case of isochronous URB in the while loop, iso_buffer is
allocated and after sending it to server, buffer is deallocated. And
then, if the next URB in the while loop is not a isochronous pipe,
iso_buffer still holds the previously deallocated buffer address and
kfree tries to free wrong buffer address.

The arguments to queue_trb are always byteswapped to LE for placement in
the ring, but this should not happen in the case of immediate data; the
bytes copied out of transfer_buffer are already in the correct order.
Add a complementary byteswap so the bytes end up in the ring correctly.
This was observed on BE ppc64 with a "Texas Instruments TUSB73x0
SuperSpeed USB 3.0 xHCI Host Controller [104c:8241]" as a ch341
usb-serial adapter ("1a86:7523 QinHeng Electronics HL-340 USB-Serial

commit ef513be0a9 ("usb: xhci: Add Clear_TT_Buffer") schedules work
to clear TT buffer, but causes a use-after-free regression at the same time
Make sure hub_tt_work finishes before endpoint is disabled, otherwise
the work will dereference already freed endpoint and device related
pointers.
This was triggered when usb core failed to read the configuration
descriptor of a FS/LS device during enumeration.
xhci driver queued clear_tt_work while usb core freed and reallocated
a new device for the next enumeration attempt.
EHCI driver implents ehci_endpoint_disable() that makes sure
clear_tt_work has finished before it returns, but xhci lacks this support.
usb core will call hcd->driver->endpoint_disable() callback before
disabling endpoints, so we want this in xhci as well.
The added xhci_endpoint_disable() is based on ehci_endpoint_disable()

The custom ring-buffer implementation was merged without any locking or
explicit memory barriers, but a spinlock was later added by commit
9d33efd9a7 ("USB: ldusb bugfix").
The lock did not cover the update of the tail index once the entry had
been processed, something which could lead to memory corruption on
weakly ordered architectures or due to compiler optimisations.
Specifically, a completion handler running on another CPU might observe
the incremented tail index and update the entry before ld_usb_read() is
done with it.

Not much here, only 14 commits in different drivers.
As for the specifics, Roger Quadros fixed an important bug in cdns3

behind the UDC framework's back.
The Atmel UDC got a fix for interrupt storm in FIFO mode, this was done

Apart from these, we have the usual set of non-critical fixes.

In dwc3_pci_probe a call to platform_device_alloc allocates a device
which is correctly put in case of error except one case: when the call to
platform_device_add_properties fails it directly returns instead of
going to error handling. This commit replaces return with the goto.

composite_dev_cleanup call from the failure of configfs_composite_bind
frees up the cdev->os_desc_req and cdev->req. If the previous calls of
bind and unbind is successful these will carry stale values.
Consider the below sequence of function calls:
configfs_composite_bind()
composite_dev_prepare()
- Allocate cdev->req, cdev->req->buf
composite_os_desc_req_prepare()
- Allocate cdev->os_desc_req, cdev->os_desc_req->buf
configfs_composite_unbind()
composite_dev_cleanup()
- free the cdev->os_desc_req->buf and cdev->req->buf
Next composition switch
configfs_composite_bind()
- If it fails goto err_comp_cleanup will call the
composite_dev_cleanup() function
composite_dev_cleanup()
- calls kfree up with the stale values of cdev->req->buf and
cdev->os_desc_req from the previous configfs_composite_bind
call. The free call on these stale values leads to double free.
Hence, Fix this issue by setting request and buffer pointer to NULL after
kfree.

"Fix a performance regression that followed from a fix to the
conversion of the fsdax implementation to the xarray. v5.3 users
report that they stop seeing huge page mappings on an application +
filesystem layout that was seeing huge pages previously on v5.2"

fs/dax: Fix pmd vs pte conflict detection
Nine changes, eight to drivers (qla2xxx, hpsa, lpfc, alua, ch,
53c710[x2], target) and one core change that tries to close a race
between sysfs delete and module removal.

"Nine changes, eight to drivers (qla2xxx, hpsa, lpfc, alua, ch,

between sysfs delete and module removal"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: lpfc: remove left-over BUILD_NVME defines
scsi: core: try to get module before removing device
scsi: hpsa: add missing hunks in reset-patch
scsi: target: core: Do not overwrite CDB byte 1
scsi: ch: Make it possible to open a ch device multiple times again
scsi: fix kconfig dependency warning related to 53C700_LE_ON_BE
scsi: sni_53c710: fix compilation error
scsi: scsi_dh_alua: handle RTPG sense code correctly during state transitions
scsi: qla2xxx: fix a potential NULL pointer dereference
If we always compile the get_break_insn_length inline function we can
remove the ifdefs and let dead code elimination take care of the warn
branch that is now unreadable because the report_bug stub always
returns BUG_TRAP_TYPE_BUG.
