Commit 99fc86450c439039d2ef88d06b222fd51a779176 "ALSA: usb-mixer: parse descriptors with structs" introduced a set of useful parsers for descriptors. Unfortunately the parses for the Processing Unit Descriptor came with a very subtle bug... Functions uac_processing_unit_iProcessing() and uac_processing_unit_specific() were indexing the baSourceID array forgetting the fields before the iProcessing and process-specific descriptors. The problem was observed with Sound Blaster Extigy mixer, where nNrModes in Up/Down-mix Processing Unit Descriptor was accessed at offset 10 of the descriptor (value 0) instead of offset 15 (value 7). In result the resulting control had interesting limit values: Simple mixer control 'Channel Routing Mode Select',0 Capabilities: volume volume-joined penum Playback channels: Mono Capture channels: Mono Limits: 0 - -1 Mono: -1 [100%] Fixed by starting from the bmControls, which was calculated correctly, instead of baSourceID. Now the mentioned control is fine: Simple mixer control 'Channel Routing Mode Select',0 Capabilities: volume volume-joined penum Playback channels: Mono Capture channels: Mono Limits: 0 - 6 Mono: 0 [0%] Signed-off-by: Pawel Moll <mail@pawelmoll.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| * USB: add NO_D3_DURING_SLEEP flag and revert 151b61284776be2Alan Stern2012-06-221-2/+0

This patch (as1558) fixes a problem affecting several ASUS computers: The machine crashes or corrupts memory when going into suspend if the ehci-hcd driver is bound to any controllers. Users have been forced to unbind or unload ehci-hcd before putting their systems to sleep. After extensive testing, it was determined that the machines don't like going into suspend when any EHCI controllers are in the PCI D3 power state. Presumably this is a firmware bug, but there's nothing we can do about it except to avoid putting the controllers in D3 during system sleep. The patch adds a new flag to indicate whether the problem is present, and avoids changing the controller's power state if the flag is set. Runtime suspend is unaffected; this matters only for system suspend. However as a side effect, the controller will not respond to remote wakeup requests while the system is asleep. Hence USB wakeup is not functional -- but of course, this is already true in the current state of affairs. A similar patch has already been applied as commit 151b61284776be2d6f02d48c23c3625678960b97 (USB: EHCI: fix crash during suspend on ASUS computers). The patch supersedes that one and reverts it. There are two differences: The old patch added the flag at the USB level; this patch adds it at the PCI level. The old patch applied to all chipsets with the same vendor, subsystem vendor, and product IDs; this patch makes an exception for a known-good system (based on DMI information).

| * usbnet: fix skb traversing races during unlink(v2)Ming Lei2012-05-211-1/+2

Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid recursive locking in usbnet_stop()) fixes the recursive locking problem by releasing the skb queue lock before unlink, but may cause skb traversing races: - after URB is unlinked and the queue lock is released, the refered skb and skb->next may be moved to done queue, even be released - in skb_queue_walk_safe, the next skb is still obtained by next pointer of the last skb - so maybe trigger oops or other problems This patch extends the usage of entry->state to describe 'start_unlink' state, so always holding the queue(rx/tx) lock to change the state if the referd skb is in rx or tx queue because we need to know if the refered urb has been started unlinking in unlink_urbs. The other part of this patch is based on Huajun's patch: always traverse from head of the tx/rx queue to get skb which is to be unlinked but not been started unlinking.

| * USB: Remove duplicate USB 3.0 hub feature #defines.Sarah Sharp2012-02-291-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit d9f5343e35d9138432657202afa8e3ddb2ade360 upstream. Somehow we ended up with duplicate hub feature #defines in ch11.h. Tatyana Brokhman first created the USB 3.0 hub feature macros in 2.6.38 with commit 0eadcc09203349b11ca477ec367079b23d32ab91 "usb: USB3.0 ch11 definitions". In 2.6.39, I modified a patch from John Youn that added similar macros in a different place in the same file, and committed dbe79bbe9dcb22cb3651c46f18943477141ca452 "USB 3.0 Hub Changes". Some of the #defines used different names for the same values. Others used exactly the same names with the same values, like these gems: #define USB_PORT_FEAT_BH_PORT_RESET 28 ... #define USB_PORT_FEAT_BH_PORT_RESET 28 According to my very geeky husband (who looked it up in the C99 spec), it is allowed to have object-like macros with duplicate names as long as the replacement list is exactly the same. However, he recalled that some compilers will give warnings when they find duplicate macros. It's probably best to remove the duplicates in the stable tree, so that the code compiles for everyone. The macros are now fixed to move the feature requests that are specific to USB 3.0 hubs into a new section (out of the USB 2.0 hub feature section), and use the most common macro name. This patch should be backported to 2.6.39.

[ removed the dwc3 portion of the patch as it didn't apply to older kernels - gregkh] According to USB 3.0 Specification Table 9-22, if bmAttributes [4:0] are set to zero, it means "no streams supported", but the way this helper was defined on Linux, we will *always* have one stream which might cause several problems. For example on DWC3, we would tell the controller endpoint has streams enabled and yet start transfers with Stream ID set to 0, which would goof up the host side. While doing that, convert the macro to an inline function due to the different checks we now need.

| * usb: gadget: composite: Allow function drivers to pause control transfersRoger Quadros2011-05-101-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some USB function drivers (e.g. f_mass_storage.c) need to delay or defer the data/status stages of standard control requests like SET_CONFIGURATION or SET_INTERFACE till they are done with their bookkeeping and are actually ready for accepting new commands to their interface. They can now achieve this functionality by returning USB_GADGET_DELAYED_STATUS in their setup handlers (e.g. set_alt()). The composite framework will then defer completion of the control transfer by not completing the data/status stages. This ensures that the host does not send new packets to the interface till the function driver is ready to take them. When the function driver that requested for USB_GADGET_DELAYED_STATUS is done with its bookkeeping, it should signal the composite framework to continue with the data/status stages of the control transfer. It can do so by invoking the new API usb_composite_setup_continue(). This is where the control transfer's data/status stages are completed and host can initiate new transfers. The DELAYED_STATUS mechanism is currently only supported if the expected data phase is 0 bytes (i.e. w_length == 0). Since SET_CONFIGURATION and SET_INTERFACE are the only cases that will use this mechanism, this is not a limitation.

| |/ | | | | | | | | | | | | | | | | | | | | USB tethering does not work anymore since 2.6.39-rc2, but it's okay in -rc1. The root cause is the new added mask code 'FLAG_POINTTOPOINT' overlaps 'FLAG_MULTI_PACKET' in include/linux/usb/usbnet.h, this causes logic issue in rx_process(). This patch cleans up the overlap.

* | usbnet: use eth%d name for known ethernet devicesArnd Bergmann2011-04-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation for the USB ethernet devices suggests that only some devices are supposed to use usb0 as the network interface name instead of eth0. The logic used there, and documented in Kconfig for CDC is that eth0 will be used when the mac address is a globally assigned one, but usb0 is used for the locally managed range that is typically used on point-to-point links. Unfortunately, this has caused a lot of pain on the smsc95xx device that is used on the popular pandaboard without an EEPROM to store the MAC address, which causes the driver to call random_ether_address(). Obviously, there should be a proper MAC addressed assigned to the device, and discussions are ongoing about how to solve this, but this patch at least makes sure that the default interface naming gets a little saner and matches what the user can expect based on the documentation, including for new devices. The approach taken here is to flag whether a device might be a point-to-point link with the new FLAG_POINTTOPOINT setting in the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one of the two. The usbnet framework only looks at the MAC address for device naming if both flags are set, otherwise it trusts the flag.

* | net/usb: Ethernet quirks for the LG-VL600 4G modemAndrzej Zaborowski2011-03-301-0/+3
|/ | | | | | | | | | | | | | | | | | | This adds a driver for the CDC Ethernet part of this modem. The device's ID is blacklisted in cdc_ether.c and is white-listed in this new driver because of the quirks needed to make it useful. The modem's firmware exposes a CDC ACM port for modem control and a CDC Ethernet port for network data. The descriptors look fine but both ports actually are some sort of multiplexers requiring non- standard headers added/removed from every packet or they get ignored. All information is based on a usb traffic log from a Windows machine. On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps. Userspace scripts are required to talk to the CDC ACM port. Signed-off-by: Andrzej Zaborowski <balrogg@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* | | USB: Remove bogus USB_PORT_STAT_SUPER_SPEED symbol.Sarah Sharp2011-03-131-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB_PORT_STAT_SUPER_SPEED is a made up symbol that the USB core used to track whether USB ports had a SuperSpeed device attached. This is a linux-internal symbol that was used when SuperSpeed and non-SuperSpeed devices would show up under the same xHCI roothub. This particular port status is never returned by external USB 3.0 hubs. (Instead they have a USB_PORT_STAT_SPEED_5GBPS that uses a completely different speed mask.) Now that the xHCI driver registers two roothubs, USB 3.0 devices will only show up under USB 3.0 hubs. Rip out USB_PORT_STAT_SUPER_SPEED and replace it with calls to hub_is_superspeed().

* | | usb: Make core allocate resources per PCI-device.Sarah Sharp2011-03-131-0/+7

This patch is the start of the work to separate the xHCI host controller into two roothubs: a USB 3.0 roothub with SuperSpeed-only ports, and a USB 2.0 roothub with HS/FS/LS ports. One usb_hcd structure is designated to be the "primary HCD", and a pointer is added to the usb_hcd structure to keep track of that. A new function call, usb_hcd_is_primary_hcd() is added to check whether the USB hcd is marked as the primary HCD (or if it is not part of a roothub pair). To allow the USB core and xHCI driver to access either roothub in a pair, a "shared_hcd" pointer is added to the usb_hcd structure. Add a new function, usb_create_shared_hcd(), that does roothub allocation for paired roothubs. It will act just like usb_create_hcd() did if the primary_hcd pointer argument is NULL. If it is passed a non-NULL primary_hcd pointer, it sets usb_hcd->shared_hcd and usb_hcd->primary_hcd fields. It will also skip the bandwidth_mutex allocation, and set the secondary hcd's bandwidth_mutex pointer to the primary HCD's mutex. IRQs are only allocated once for the primary roothub. Introduce a new usb_hcd driver flag that indicates the host controller driver wants to create two roothubs. If the HCD_SHARED flag is set, then the USB core PCI probe methods will allocate a second roothub, and make sure that second roothub gets freed during rmmod and in initialization error paths. When usb_hc_died() is called with the primary HCD, make sure that any roothubs that share that host controller are also marked as being dead.

* | | usb: Store bus type in usb_hcd, not in driver flags.Sarah Sharp2011-03-131-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The xHCI driver essentially has both a USB 2.0 and a USB 3.0 roothub. So setting the HCD_USB3 bits in the hcd->driver->flags is a bit misleading. Add a new field to usb_hcd, bcdUSB. Store the result of hcd->driver->flags & HCD_MASK in it. Later, when we have the xHCI driver register the two roothubs, we'll set the usb_hcd->bcdUSB field to HCD_USB2 for the USB 2.0 roothub, and HCD_USB3 for the USB 3.0 roothub.

These hubs have a slightly different hub descriptor than USB 2.0 hubs, with a fixed (rather than variable length) size. Change the USB core's hub descriptor to have a union for the last fields that differ. Change the host controller drivers that access those last fields (DeviceRemovable and PortPowerCtrlMask) to use the union. Translate the new version of the hub port status field into the old version that khubd understands. (Note: we need to fix it to translate the roothub's port status once we stop converting it to USB 2.0 hub status internally.) Add new code to handle link state change status. Send out new control messages that are needed for USB 3.0 hubs, like Set Hub Depth. This patch is a modified version of the original patch submitted by John Youn. It's updated to reflect the removal of the "bitmap" #define, and change the hub descriptor accesses of a couple new host controller drivers.
