Conflicts were simply overlapping changes.  In the net/ipv4/route.c
case the code had simply moved around a little bit and the same fix
was made in both 'net' and 'net-next'.

In the net/sched/sch_generic.c case a fix in 'net' happened at
the same time that a new argument was added to qdisc_hash_add().

Linus Torvalds 025def92dd Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target fixes from Nicholas Bellinger:

 "There has been work in a number of different areas over the last
  weeks, including:

   - Fix target-core-user (TCMU) back-end bi-directional handling (Xiubo
     Li + Mike Christie + Ilias Tsitsimpis)

   - Fix iscsi-target TMR reference leak during session shutdown (Rob
     Millner + Chu Yuan Lin)

   - Fix target_core_fabric_configfs.c race between LUN shutdown +
     mapped LUN creation (James Shen)

   - Fix target-core unknown fabric callback queue-full errors (Potnuri
     Bharat Teja)

   - Fix iscsi-target + iser-target queue-full handling in order to
     support iw_cxgb4 RNICs. (Potnuri Bharat Teja + Sagi Grimberg)

   - Fix ALUA transition state race between multiple initiator (Mike
     Christie)

   - Drop work-around for legacy GlobalSAN initiator, to allow QLogic
     57840S + 579xx offload HBAs to work out-of-the-box in MSFT
     environments. (Martin Svec + Arun Easi)

  Note that a number are CC'ed for stable, and although the queue-full
  bug-fixes required for iser-target to work with iw_cxgb4 aren't CC'ed
  here, they'll be posted to Greg-KH separately"

Mathias Nyman d3519b9d96 xhci: Manually give back cancelled URB if we can't queue it for cancel
xhci needs to take care of four scenarios when asked to cancel a URB.

1 URB is not queued or already given back.
  usb_hcd_check_unlink_urb() will return an error, we pass the error on

2 We fail to find xhci internal structures from urb private data such as
  virtual device and endpoint ring.
  Give back URB immediately, can't do anything about internal structures.

3 URB private data has valid pointers to xhci internal data, but host is
  not  responding.
  give back URB immedately and remove the URB from the endpoint lists.

4 Everyting is working
  add URB to cancel list, queue a command to stop the endpoint, after
  which the URB can be turned to no-op or skipped, removed from lists,
  and given back.

We failed to give back the urb in case 2 where the correct device and
endpoint pointers could not be retrieved from URB private data.

This caused a hang on Dell Inspiron 5558/0VNM2T at resume from suspend
as urb was never returned.

warned about a "unexpected TRB Type 4", and did not set the

Alan Stern 1633682053 USB: fix linked-list corruption in rh_call_control()
Using KASAN, Dmitry found a bug in the rh_call_control() routine: If
buffer allocation fails, the routine returns immediately without
unlinking its URB from the control endpoint, eventually leading to
linked-list corruption.

This patch fixes the problem by jumping to the end of the routine
(where the URB is unlinked) when an allocation failure occurs.

Johan Hovold 687e0687f7 USB: usbtmc: add missing endpoint sanity check
USBTMC devices are required to have a bulk-in and a bulk-out endpoint,
but the driver failed to verify this, something which could lead to the
endpoint addresses being taken from uninitialised memory.

Make sure to zero all private data as part of allocation, and add the
missing endpoint sanity check.

Note that this also addresses a more recently introduced issue, where
the interrupt-in-presence flag would also be uninitialised whenever the
optional interrupt-in endpoint is not present. This in turn could lead
to an interrupt urb being allocated, initialised and submitted based on
uninitialised values.

Bin Liu bc1e215454 usb: musb: fix possible spinlock deadlock
The DSPS glue calls del_timer_sync() in its musb_platform_disable()
implementation, which requires the caller to not hold a lock. But
musb_remove() calls musb_platform_disable() will musb->lock held. This
could causes spinlock deadlock.

So change musb_remove() to call musb_platform_disable() without holds
musb->lock. This doesn't impact the musb_platform_disable implementation
in other glue drivers.

Samuel Thibault 3243367b20 usb-core: Add LINEAR_FRAME_INTR_BINTERVAL USB quirk
Some USB 2.0 devices erroneously report millisecond values in
bInterval. The generic config code manages to catch most of them,
but in some cases it's not completely enough.

The case at stake here is a USB 2.0 braille device, which wants to
announce 10ms and thus sets bInterval to 10, but with the USB 2.0
computation that yields to 64ms.  It happens that one can type fast
enough to reach this interval and get the device buffers overflown,
leading to problematic latencies.  The generic config code does not
catch this case because the 64ms is considered a sane enough value.

This change thus adds a USB_QUIRK_LINEAR_FRAME_INTR_BINTERVAL quirk
to mark devices which actually report milliseconds in bInterval,
and marks Vario Ultra devices as needing it.

Note that the endpoint access that causes the NULL-deref is currently

Guenter Roeck dcc7620cad usb: host: xhci-plat: Fix timeout on removal of hot pluggable xhci controllers
Upstream commit 98d74f9cea ("xhci: fix 10 second timeout on removal of
PCI hotpluggable xhci controllers") fixes a problem with hot pluggable PCI
xhci controllers which can result in excessive timeouts, to the point where
the system reports a deadlock.

The same problem is seen with hot pluggable xhci controllers using the
xhci-plat driver, such as the driver used for Type-C ports on rk3399.
Similar to hot-pluggable PCI controllers, the driver for this chip
removes the xhci controller from the system when the Type-C cable is
disconnected.

The solution for PCI devices works just as well for non-PCI devices
and avoids the problem.

are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an

(like before patch 2e2aa1bc7eff90ecm.)

Tested on an Atmel AT91SAM9G20 with an on-board TI TUSB2046B hub chip
If the last USB device is unplugged from the USB hub, the hub goes into

Johan Hovold 8c76d7cd52 USB: serial: safe_serial: fix information leak in completion handler
Add missing sanity check to the bulk-in completion handler to avoid an
integer underflow that could be triggered by a malicious device.

This avoids leaking up to 56 bytes from after the URB transfer buffer to
user space.
