USB: fix usbmon BUG trigger

2018-03-03T15:50:57+00:00

commit 46eb14a6e1585d99c1b9f58d0e7389082a5f466b upstream.

Automated tests triggered this by opening usbmon and accessing the
mmap while simultaneously resizing the buffers. This bug was with
us since 2006, because typically applications only size the buffers
once and thus avoid racing. Reported by Kirill A. Shutemov.

xhci: Don't add a virt_dev to the devs array before it's fully allocated

2018-03-03T15:50:45+00:00

commit 5d9b70f7d52eb14bb37861c663bae44de9521c35 upstream.

Avoid null pointer dereference if some function is walking through the
devs array accessing members of a new virt_dev that is mid allocation.

Add the virt_dev to xhci->devs[i] _after_ the virt_device and all its
members are properly allocated.

issue found by KASAN: null-ptr-deref in xhci_find_slot_id_by_port

"Quick analysis suggests that xhci_alloc_virt_device() is not mutex
protected. If so, there is a time frame where xhci->devs[slot_id] is set
but not fully initialized. Specifically, xhci->devs[i]->udev can be NULL."

USB: uas and storage: Add US_FL_BROKEN_FUA for another JMicron JMS567 ID

2018-03-03T15:50:45+00:00

commit 62354454625741f0569c2cbe45b2d192f8fd258e upstream.

There is another JMS567-based USB3 UAS enclosure (152d:0578) that fails
with the following error:

[sda] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
[sda] tag#0 Sense Key : Illegal Request [current]
[sda] tag#0 Add. Sense: Invalid field in cdb

The issue occurs both with UAS (occasionally) and mass storage
(immediately after mounting a FS on a disk in the enclosure).

Enabling US_FL_BROKEN_FUA quirk solves this issue.

This patch adds an UNUSUAL_DEV with US_FL_BROKEN_FUA for the enclosure
for both UAS and mass storage.

xhci: Don't show incorrect WARN message about events for empty rings

2018-03-03T15:50:42+00:00

commit e4ec40ec4b260efcca15089de4285a0a3411259b upstream.

xHC can generate two events for a short transfer if the short TRB and
last TRB in the TD are not the same TRB.

The driver will handle the TD after the first short event, and remove
it from its internal list. Driver then incorrectly prints a warning
for the second event:

"WARN Event TRB for slot x ep y with no TDs queued"

Fix this by not printing a warning if we get a event on a empty list
if the previous event was a short event.
