commit 1aa9578c1a9450fb21501c4f549f5b1edb557e6d upstream.
Don Zickus <dzickus@redhat.com> writes:
Some co-workers of mine bought Samsung laptops that had mostly usb3 ports.
Those ports did not resume correctly (the driver would timeout communicating
and fail). This led to frustration as suspend/resume is a common use for
laptops.
Poking around, I applied the reset on resume quirk to this chipset and the
resume started working. Reloading the xhci_hcd module had been the temporary
workaround.

commit e2ed511400d41e0d136089d5a55ceab57c6a2426 upstream.
This reverts commit 247bf557273dd775505fb9240d2d152f4f20d304.
This commit, together with commit 3804fad45411b48233b48003e33a78f290d227c8
"USBNET: ax88179_178a: enable tso if usb host supports sg dma" were
origially added to get xHCI 1.0 hosts and usb ethernet ax88179_178a devices
working together with scatter gather. xHCI 1.0 hosts pose some requirement on how transfer
buffers are aligned, setting this requirement for 1.0 hosts caused USB 3.0 mass
storage devices to fail more frequently.
USB 3.0 mass storage devices used to work before 3.14-rc1. Theoretically,
the TD fragment rules could have caused an occasional disk glitch.
Now the devices *will* fail, instead of theoretically failing.
>From a user perspective, this looks like a regression; the USB device obviously
fails on 3.14-rc1, and may sometimes silently fail on prior kernels.
The proper soluition is to implement the TD fragment rules required, but for now
this patch needs to be reverted to get USB 3.0 mass storage devices working at the
level they used to.

commit d86db25e53fa69e3e97f3b55dd82a70689787c5d upstream.
The DELAY_INIT quirk only reduces the frequency of enumeration failures
with the Logitech HD Pro C920 and C930e webcams, but does not quite
eliminate them. We have found that adding a delay of 100ms between the
first and second Get Configuration request makes the device enumerate
perfectly reliable even after several weeks of extensive testing. The
reasons for that are anyone's guess, but since the DELAY_INIT quirk
already delays enumeration by a whole second, wating for another 10th of
that isn't really a big deal for the one other device that uses it, and
it will resolve the problems with these webcams.

commit e0429362ab15c46ea4d64c3f8c9e0933e48a143a upstream.
We've encountered a rare issue when enumerating two Logitech webcams
after a reboot that doesn't power cycle the USB ports. They are spewing
random data (possibly some leftover UVC buffers) on the second
(full-sized) Get Configuration request of the enumeration phase. Since
the data is random this can potentially cause all kinds of odd behavior,
and since it occasionally happens multiple times (after the kernel
issues another reset due to the garbled configuration descriptor), it is
not always recoverable. Set the USB_DELAY_INIT quirk that seems to work
around the issue.

commit 02c123ee99c793f65af2dbda17d5fe87d448f808 upstream.
Commit "usb: pci-quirks: refactor AMD quirk to abstract AMD chipset types"
introduced a new AMD chipset type to filter AMD platforms with different
chipsets.
According to a recent thread [1], this patch updates SB800 prefetch routine
in AMD PLL quirk. And make it use the new chipset type to represent SB800
generation.

commit 22b4f0cd1d4d98f50213e9a37ead654e80b54b9d upstream.
This patch abstracts out a AMD chipset type which includes southbridge
generation and its revision. When os excutes usb_amd_find_chipset_info
routine to initialize AMD chipset type, driver will know which kind of
chipset is used.
This update has below benifits:
- Driver is able to confirm which southbridge generations and their
revision are used, with chipset detection once.
- To describe chipset generations with enumeration types brings better
readability.
- It's flexible to filter AMD platforms to implement new quirks in future.

commit 3e8d6d85adedc59115a564c0a54b36e42087c4d9 upstream.
High-speed USB connections revert back to full-speed signalling when
the device goes into suspend. This takes several milliseconds, and
during that time it's not possible to tell reliably whether the device
has been disconnected.
On some platforms, the Wake-On-Disconnect circuitry gets confused
during this intermediate state. It generates a false wakeup signal,
which can prevent the controller from going to sleep.
To avoid this problem, this patch adds a 5-ms delay to the
ehci_bus_suspend() routine if any ports have to switch over to
full-speed signalling. (Actually, the delay was already present for
devices using a particular kind of PHY power management; the patch
merely causes the delay to be used more widely.)

commit 2d1f7af3d60dd09794e0738a915d272c6c27abc5 upstream.
Commit 3dc6475 ("bcm63xx_enet: add support Broadcom BCM6345 Ethernet")
changed the ENETDMA[CS] macros such that they are no longer macros, but
actual register offset definitions. The bcm63xx_udc driver was not
updated, and as a result, causes the following build error to pop up:
CC drivers/usb/gadget/u_ether.o
drivers/usb/gadget/bcm63xx_udc.c: In function 'iudma_write':
drivers/usb/gadget/bcm63xx_udc.c:642:24: error: called object '0' is not

a function
drivers/usb/gadget/bcm63xx_udc.c:700:49: error: called object '0' is not
a function
Fix this by updating usb_dmac_{read,write}l and usb_dmas_{read,write}l to
take an extra channel argument, and use the channel width
(ENETDMA_CHAN_WIDTH) to offset the register we want to access, hence
doing again what the macro implicitely did for us.

commit 140e3026a57ab7d830dab2f2c57796c222db0ea9 upstream.
Commit 9df89d85b407690afa46ddfbccc80bec6869971d "usbcore: set
lpm_capable field for LPM capable root hubs" was created under the
assumption that all USB host controllers should have USB 3.0 Link PM
enabled for all devices under the hosts.
Unfortunately, that's not the case. The xHCI driver relies on knowledge
of the host hardware scheduler to calculate the LPM U1/U2 timeout
values, and it only sets lpm_capable to one for Intel host controllers
(that have the XHCI_LPM_SUPPORT quirk set).
When LPM is enabled for some Fresco Logic hosts, it causes failures with
a AgeStar 3UBT USB 3.0 hard drive dock:

commit 247bf557273dd775505fb9240d2d152f4f20d304 upstream.
xHCI 1.0 hosts have a set of requirements on how to align transfer
buffers on the endpoint rings called "TD fragment" rules. When the
ax88179_178a driver added support for scatter gather in 3.12, with
commit 804fad45411b48233b48003e33a78f290d227c8 "USBNET: ax88179_178a:
enable tso if usb host supports sg dma", it broke the device under xHCI
1.0 hosts. Under certain network loads, the device would see an
unexpected short packet from the host, which would cause the device to
stop sending ethernet packets, even through USB packets would still be
sent.
Commit 35773dac5f86 "usb: xhci: Link TRB must not occur within a USB
payload burst" attempted to fix this. It was a quick hack to partially
implement the TD fragment rules. However, it caused regressions in the
usb-storage layer and userspace USB drivers using libusb. The patches
to attempt to fix this are too far reaching into the USB core, and we
really need to implement the TD fragment rules correctly in the xHCI
driver, instead of continuing to wallpaper over the issues.
Disable arbitrarily-aligned scatter-gather in the xHCI driver for 1.0
hosts. Only the ax88179_178a driver checks the no_sg_constraint flag,
so don't set it for 1.0 hosts. This should not impact usb-storage or
usbfs behavior, since they pass down max packet sized aligned sg-list
entries (512 for USB 2.0 and 1024 for USB 3.0).

commit 823d12c95c666fa7ab7dad208d735f6bc6afabdc upstream.
People sometimes create their own custom-configured kernels and forget
to enable CONFIG_SCSI_MULTI_LUN. This causes problems when they plug
in a USB storage device (such as a card reader) with more than one
LUN.
Fortunately, we can tell fairly easily when a storage device claims to
have more than one LUN. When that happens, this patch asks the SCSI
layer to probe all the LUNs automatically, regardless of the config
setting.
The patch also updates the Kconfig help text for usb-storage,
explaining that CONFIG_SCSI_MULTI_LUN may be necessary.

The Cypress ATACB unusual-devs entry for the Super Top SATA bridge
causes problems. Although it was originally reported only for
bcdDevice = 0x160, its range was much larger. This resulted in a bug

Milan reports errors with bcdDevice 0x150.
Therefore this patch restricts the range to just 0x160.

There is no need to skip querying the config and string descriptors for
unauthorized WUSB devices when usb_new_device is called. It is allowed
by WUSB spec. The only action that needs to be delayed until
authorization time is the set config. This change allows user mode
tools to see the config and string descriptors earlier in enumeration
which is needed for some WUSB devices to function properly on Android
systems. It also reduces the amount of divergent code paths needed
for WUSB devices.

commit f2d9b991c549f159dc9ae81f77d8206c790cbfee upstream.
Commit 35773dac5f862cb1c82ea151eba3e2f6de51ec3e "usb: xhci: Link TRB
must not occur within a USB payload burst" attempted to fix an issue
found with USB ethernet adapters, and inadvertently broke USB storage
devices. The patch attempts to ensure that transfers never span a
segment, and rejects transfers that have more than 63 entries (or
possibly less, if some entries cross 64KB boundaries).
usb-storage limits the maximum transfer size to 120K, and we had assumed
the block layer would pass a scatter-gather list of 4K entries,
resulting in no more than 31 sglist entries:
http://marc.info/?l=linux-usb&m=138498190419312&w=2
That assumption was wrong, since we've seen the driver reject a write
that was 218 sectors long (of probably 512 bytes each):
Jan 1 07:04:49 jidanni5 kernel: [ 559.624704] xhci_hcd 0000:00:14.0: Too many fragments 79, max 63
...
Jan 1 07:04:58 jidanni5 kernel: [ 568.622583] Write(10): 2a 00 00 06 85 0e 00 00 da 00
Limit the number of scatter-gather entries to half a ring segment. That
should be margin enough in case some entries cross 64KB boundaries.
Increase the number of TRBs per segment from 64 to 256, which should
result in ring segments fitting on a 4K page.

commit d6c9ea9069af684358efedcaf2f2f687f51c58ee upstream.
Currently prepare_ring() returns -ENOMEM if the urb won't fit into a
single ring segment. usb_sg_wait() treats this error as a temporary
condition and will keep retrying until something else goes wrong.
The number of retries should be limited in usb_sg_wait(), but also
prepare_ring() should not return an error code that suggests it might
be worth retrying. Change it to -EINVAL.

commit feffe09f510c475df082546815f9e4a573f6a233 upstream.
According to Freescale imx28 Errata, "ENGR119653 USB: ARM to USB
register error issue", All USB register write operations must
use the ARM SWP instruction. So, we implement a special ehci_write
for imx28.
Discussion for it at below:
http://marc.info/?l=linux-usb&m=137996395529294&w=2
Without this patcheset, imx28 works unstable at high AHB bus loading.
If the bus loading is not high, the imx28 usb can work well at the most
of time. There is a IC errata for this problem, usually, we consider
IC errata is a problem not a new feature, and this workaround is needed
for that, so we need to add them to stable tree 3.11+.

commit 543d7784b07ffd16cc82a9cb4e1e0323fd0040f1 upstream.
There is a race in the hub driver between hub_disconnect() and
recursively_mark_NOTATTACHED(). This race can be triggered if the
driver is unbound from a device at the same time as the bus's root hub
is removed. When the race occurs, it can cause an oops:

One problem is that recursively_mark_NOTATTACHED() uses the intfdata
value and hub->hdev->maxchild while hub_disconnect() is clearing them.
Another problem is that it uses hub->ports[i] while the port device is
being released.
To fix this race, we need to hold the device_state_lock while
hub_disconnect() changes the values. (Note that usb_disconnect()
and hub_port_connect_change() already acquire this lock at similar
critical times during a USB device's life cycle.) We also need to
remove the port devices after maxchild has been set to 0, instead of
before.

commit c1f15196ac3b541d084dc80a8fbd8a74c6a0bd44 upstream.
Genuine FTDI chips support only CS7/8. A previous fix in commit
8704211f65a2 ("USB: ftdi_sio: fixed handling of unsupported CSIZE
setting") enforced this limitation and reported it back to userspace.
However, certain types of smartcard readers depend on specific
driver behaviour that requests 0 data bits (not 5) to change into a
different operating mode if CS5 has been set.
This patch reenables this behaviour for all FTDI devices.
Tagged to be added to stable, because it affects a lot of users of
embedded systems which rely on these readers to work properly.

commit 623c8263376c0b8a4b0c220232e7313d762cd0cc upstream.
Some PL2303 devices are known to lose bytes if you change serial
settings even to the same values as before. Avoid this by comparing the
encoded settings with the previsouly used ones before configuring the
device.
The common case was fixed by commit bf5e5834bffc6 ("pl2303: Fix mode
switching regression"), but this problem was still possible to trigger,
for instance, by using the TCSETS2-interface to repeatedly request
115201 baud, which gets mapped to 115200 and thus always triggers a
settings update.

commit 2fc5a7dace3c43e62402ab4e8800a8f1834ffe2a upstream.
We have met a bug that the high bandwidth ISO-TX transfer has failed
at the last packet if it is less than 1024, the TD status shows it
is "Transaction Error".
The root cause of this problem is: the mult value at qh is not correct
for current TD's transfer length. We use TD list to queue un-transfer
TDs, and change mult for new adding TDs. If new adding TDs transfer length
less than 1024, but the queued un-transfer TDs transfer length is larger
than 1024, the transfer error will occur, and vice versa.
Usually, this problem occurs at the last packet, and the first packet for
new frame.
We fixed this problem by setting Mult at QH as the largest value (3), and
set MultO (Multiplier Override) at TD according to every transfer length.
It can cover both hardware version less than 2.3 (the real mult is MultO
if it is not 0) and 2.3+ (the real mult is min(qh.mult, td.multo)).
Since the MultO bits are only existed at TX TD, we keep the ISO-RX behavior
unchanged.

commit 6962d914f317b119e0db7189199b21ec77a4b3e0 upstream.
We've got regression reports that my previous fix for spurious wakeups
after S5 on HP Haswell machines leads to the automatic reboot at
shutdown on some machines. It turned out that the fix for one side
triggers another BIOS bug in other side. So, it's exclusive.
Since the original S5 wakeups have been confirmed only on HP machines,
it'd be safer to apply it only to limited machines. As a wild guess,
limiting to machines with HP PCI SSID should suffice.
This patch should be backported to kernels as old as 3.12, that
contain the commit 638298dc66ea36623dbc2757a24fc2c4ab41b016 "xhci: Fix

commit 6f6485463aada1ec6a0f3db6a03eb8e393d6bb55 upstream.
Fix race in generic write implementation, which could lead to
temporarily degraded throughput.
The current generic write implementation introduced by commit
27c7acf22047 ("USB: serial: reimplement generic fifo-based writes") has
always had this bug, although it's fairly hard to trigger and the
consequences are not likely to be noticed.
Specifically, a write() on one CPU while the completion handler is
running on another could result in only one of the two write urbs being
utilised to empty the remainder of the write fifo (unless there is a
second write() that doesn't race during that time).
