* USB: gadget: Add EEM gadget driverBrian Niebuhr2009-09-238-48/+699
| | | | | | | | | | | | | | | | | | This patch adds a CDC EEM ethernet gadget driver. CDC EEM is a newer USB ethernet specification that uses a simpler interface than the older CDC ECM. This makes CDC EEM usable by a wider set of USB hardware. By default the ethernet gadget will still use CDC ECM/Subset, but kernel configuration and/or a module parameter will allow alternative use of the CDC EEM protocol. Changes since last version: - Brought in missing RNDIS changes that caused compile error - Modified 'sentinel CRC' checking to match EEM host driver Signed-off-by: Brian Niebuhr <bniebuhr@efjohnson.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: use kfifo to buffer usb-generic serial writesDavid VomLehn2009-09-233-81/+134
| | | | | | | | | | | | | | | | | | When do_output_char() attempts to write a carriage return/line feed sequence, it first checks to see how much buffer room is available. If there are at least two characters free, it will write the carriage return/line feed with two calls to tty_put_char(). It calls the tty_operation functions write() for devices that don't support the tty_operations function put_char(). If the USB generic serial device's write URB is not in use, it will return the buffer size when asked how much room is available. The write() of the carriage return will cause it to mark the write URB busy, so the subsequent write() of the line feed will be ignored. This patch uses the kfifo infrastructure to implement a write FIFO that accurately returns the amount of space available in the buffer.

* USB: Fix CDC EEM host driver 'sentinel' CRC validationBrian Niebuhr2009-09-231-7/+10
| | | | | | | | | | | | | This is an alternate solution to the EEM 'sentinel' CRC valiation issue. CDC EEM allows using a 'sentinel' ethernet frame CRC of 0xdeadbeef in place of a real CRC. The 'sentinel' value is transmitted in big-endian order whereas the normal CRC is little-endian. This patch handles both cases appropriately.

* USB: EHCI: ensure all watchdog timer events are deleted when suspending usbJon Hunter2009-09-231-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch was previously discussed in the following thread: http://thread.gmane.org/gmane.linux.usb.general/19472/focus=19484 On the OMAP3 device the usbhost controller is in a separate internal power-domain. So when the usbhost is inactive or suspend is called, we can disable clocks and power-down the usbhost to save power. Recently we found that after calling ehci_bus_suspend() and disabling the usbhost clocks we would see the ehci watchdog timer event fire. This was causing a kernel panic because the usbhost controllers clocks were disabled and inside the watchdog timer function the clocks were not being re-enabled, so when the ehci registers were accessed this resulted in a CPU data-abort. To avoid this panic, per recommendation from Alan Stern (see above thread), we make sure any pending timer events (that may have been scheduled by calling ehci_work within the ehci_bus_suspend() function) are deleted before returning.

* USB: Work around BIOS bugs by quiescing USB controllers earlierDavid Woodhouse2009-09-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are seeing a number of crashes in SMM, when VT-d is enabled while 'Legacy USB support' is enabled in various BIOSes. The BIOS is supposed to indicate which addresses it uses for DMA in a special ACPI table ("RMRR"), so that we can punch a hole for it when we set up the IOMMU. The problem is, as usual, that BIOS engineers are totally incompetent. They write code which will crash if the DMA goes AWOL, and then they either neglect to provide an RMRR table at all, or they put the wrong addresses in it. And of course they don't do _any_ QA, since that would take too much time away from their crack-smoking habit. The real fix, of course, is for consumers to refuse to buy motherboards which only have closed-source firmware available. If we had _open_ firmware, bugs like this would be easy to fix. Since that's something I can only dream about, this patch implements an alternative -- ensuring that the USB controllers are handed off from the BIOS and quiesced _before_ the IOMMU is initialised. That would have been a much better design than this RMRR nonsense in the first place, of course. The bootloader has no business doing DMA after the OS has booted anyway.

| | | | | | | | | | | | | | | | | | The included patch can be applied to the new usb gadget audio driver. It addresses a seg-fault in uncovered in g_audio.ko.

I suspect there may be similar problems with device /dev/snd/pcmC0D0p (FILE_PCM_PLAYBACK) handling also.

| | | | | | | | | | | | | | | | | According to the specifications, an instrument should not return more data in a DEV_DEP_MSG_IN urb than requested. However, some instruments can send more than requested. This could cause the kernel to write the extra data past the end of the buffer provided by read(). Fix this by checking that the value of the TranserSize field is not larger than the urb itself and not larger than the size of the userspace buffer. Also correctly decrement the remaining size of the buffer when userspace read()s more than USBTMC_SIZE_IOBUFFER.

| | | | | | | | | | | | | | | | | This patch (as1269) fixes a bug in the way dummy_hcd handles control URBs. Currently it returns a -EOVERFLOW error if the wLength value in the setup packet is different from the URB's transfer_buffer_length. Other host controller drivers don't do this. There's no reason the two length values have to be equal, and in fact they sometimes aren't -- a driver might set the transfer length to the maxpacket value in order to handle buggy devices that don't respect wLength.

* USB: don't lose mode switch events on suspended devicesAlan Stern2009-09-231-8/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1268) changes the way usbcore handles child devices that undergo a disconnection and reconnection while the parent hub is suspended. Currently, if the child isn't enabled for remote wakeup we leave it alone, figuring that it will go through a reset-resume when somebody tries to use it. However this isn't a good approach if the reason for the disconnection is that the child decided to switch modes or in some other way alter its descriptors. In that case we want to re-enumerate it as soon as possible, not wait until somebody forces a reset-resume. To resolve the issue, this patch treats reconnected suspended child devices as though they had requested a remote wakeup, even if they weren't enabled for it. The mode switch or descriptor change will be detected during the reset part of the reset-resume, and the device will be re-enumerated immediately. The disadvantage of this change is that it will cause autosuspended devices to be resumed when the computer wakes up from a system sleep during which the root hub was reset or lost power. This shouldn't matter much; some people would even argue that autosuspended devices should _always_ be resumed when the system wakes up!

* USB: check for hub driver not bound to root hub deviceAlan Stern2009-09-231-3/+7
| | | | | | | | | | | | | | | | | | | | This patch (as1267) changes usb_kick_khubd() and hdev_to_hub() to make them more resilient against situations where a hub device isn't bound to the hub driver. The code assumes that if a root hub was successfully registered then it must be bound to the hub driver. But this assumption can fail if the user manually unbinds the hub driver, or more importantly, if the host controller dies causing usb_set_configuration to fail. To protect against these possibilities, make hdev_to_hub() check that the hub device is configured before dereferencing the active configuration, and make usb_kick_khubd() check that the pointer to the hub's private data structure isn't NULL.

* USB: EHCI: split ehci_qh into hw and sw partsAlek Du2009-09-236-81/+127
| | | | | | | | | | | | | | | | | The ehci_qh structure merged hw and sw together which is not good: 1. More and more items are being added into ehci_qh, the ehci_qh software part are unnecessary to be allocated in DMA qh_pool. 2. If HCD has local SRAM, the sw part will consume it too, and it won't bring any benefit. 3. For non-cache-coherence system, the entire ehci_qh is uncachable, actually we only need the hw part to be uncacheable. Spliting them will let the sw part to be cacheable.

* USB: EHCI: add need_io_watchdog flag to ehci_hcdAlek Du2009-09-233-0/+10
| | | | | | | | | | | | Basically the io watchdog is only useful for those quirk HCDs. For most good ones, it only brings unnecessary wakeups. At least, I know the Intel EHCI HCDs should turn off the flag.
