usb-storage: Add ignore-residue quirk for Initio INIC-3619

2017-04-12T10:41:22+00:00

[ Upstream commit d595259fbb7a7afed241b1afb2c4fe4b47de47fa ]

This USB-SATA bridge chip is used in a StarTech enclosure for
optical drives.

Without the quirk MakeMKV fails during the key exchange with an
installed BluRay drive:
> Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - KEY NOT ESTABLISHED'
> occurred while issuing SCSI command AD010..080002400 to device 'SG:dev_11:2'

usb: dwc3: host: pass quirk-broken-port-ped property for known broken revisions

2017-04-12T10:41:19+00:00

[ Upstream commit e42a5dbb8a3d14f5a35bffa3bf7dcb87883f767a ]

dwc3 revisions <=3.00a have a limitation where Port Disable command
doesn't work. Set the quirk-broken-port-ped property for such
controllers so XHCI core can do the necessary workaround.

usb: host: xhci-plat: enable BROKEN_PED quirk if platform requested

[ Upstream commit 21939f003ad09355d9c975735750bb22aa37d8de ]

In case 'quirk-broken-port-ped' property is passed in via device property,
we should enable the corresponding BROKEN_PED quirk flag for XHCI core.

usb: xhci: add quirk flag for broken PED bits

2017-04-12T10:41:19+00:00

[ Upstream commit 41135de1e7fd14c6fcb9158404ba5c8fb97bf259 ]

Some devices from Texas Instruments [1] suffer from
a silicon bug where Port Enabled/Disabled bit
should not be used to silence an erroneous device.

The bug is so that if port is disabled with PED
bit, an IRQ for device removal (or attachment)
will never fire.

Just for the sake of completeness, the actual
problem lies with SNPS USB IP and this affects
all known versions up to 3.00a. A separate
patch will be added to dwc3 to enabled this
quirk flag if version is <= 3.00a.

usb: chipidea: msm: Rely on core to override AHBBURST

2017-04-12T10:41:19+00:00

[ Upstream commit dd3749099cfa2c80039193c438b90f3160eaf7f9 ]

The core framework already handles setting this parameter with a
platform quirk. Add the appropriate flag so that we always set
AHBBURST to 0. Technically DT should be doing this, but we always
do it for msm chipidea devices so setting the flag in the driver
works just as well. If the burst needs to be anything besides 0,
we expect the 'ahb-burst-config' dts property to be present.

commit de288e36fe33f7e06fa272bc8e2f85aa386d99aa upstream.

In the case of bounced ep0 requests, we must delay DMA operation until
after ->complete() otherwise we might overwrite contents of req->buf.

This caused problems with RNDIS gadget.

USB: fix linked-list corruption in rh_call_control()

2017-04-08T07:30:34+00:00

commit 1633682053a7ee8058e10c76722b9b28e97fb73f upstream.

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.

usb: musb: fix possible spinlock deadlock

2017-03-31T08:31:46+00:00

commit bc1e2154542071e3cfe1734b143af9b8bdacf8bd upstream.

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.

USB: usbtmc: fix probe error path

commit 2e47c53503eb9faff42b3cfa144a833344dd1f89 upstream.

Make sure to initialise the return value to avoid having allocation
failures going unnoticed when allocating interrupt-endpoint resources.

This prevents use-after-free or worse when the device is later unbound.

USB: usbtmc: add missing endpoint sanity check

2017-03-30T07:41:24+00:00

commit 687e0687f71ec00e0132a21fef802dee88c2f1ad upstream.

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.
