* [PATCH] USB: ipaq.c bugfixesFrank Gevaerts2006-07-121-5/+6
| | | | | | | | | | | | | | | | This patch fixes several problems in the ipaq.c driver with connecting and disconnecting pocketpc devices: * The read urb stayed active if the connect failed, causing nullpointer dereferences later on. * If a write failed, the driver continued as if nothing happened. Now it handles that case the same way as other usb serial devices (fix by Luiz Fernando N.

* [PATCH] USB: ehci: fix bogus alteration of a local variableDavid Brownell2006-07-121-3/+4
| | | | | | | | | | | | | | | | In a rare and all-but-unused path, the EHCI driver could reuse a variable in a way that'd make trouble. Specifically, if the first root hub port gets an overcurrent event (rare) during a remote wakeup scenario (all but unused in today's Linux, except for folk working with suspend-to-RAM and similar sleep states), that would look like a fatal error which would shut down the controller. Fix by not reusing that variable.

* [PATCH] USB serial ftdi_sio: Prevent userspace DoSIan Abbott2006-07-121-13/+90
| | | | | | | | | | | | | | | | | | | This patch limits the amount of outstanding 'write' data that can be queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or simple accidents) that use up all the system memory by writing lots of data to the serial port. The original patch was by Guillaume Autran, who in turn based it on the same mechanism implemented in the 'visor' driver. I (Ian Abbott) re-targeted the patch to the latest sources, fixed a couple of errors, renamed his new structure members, and updated the implementations of the 'write_room' and 'chars_in_buffer' methods to take account of the number of outstanding 'write' bytes. It seems to work fine, though at low baud rates it is still possible to queue up an amount of data that takes an age to shift (a job for another day!).

* [PATCH] USB serial visor: fix race in open/closeIan Abbott2006-07-121-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | The anti user-DoS mechanism in the USB serial 'visor' driver can fail in the following way: visor_open: priv->outstanding_urbs = 0 visor_write: ++priv->outstanding_urbs visor_close: visor_open: priv->outstanding_urbs = 0 visor_write_bulk_callback: --priv->outstanding_urbs So priv->outstanding_urbs ends up as (unsigned long)(-1). Not good! I haven't seen this happen with the visor driver as I don't have the hardware, but I have seen it while testing a patch to implement the same functionality in the ftdi_sio driver (patch not yet submitted). The fix is pretty simple: don't reinitialize outstanding_urbs in visor_open. (Again, I haven't tested the fix in visor, but I have tested it in ftdi_sio.)

| | | | | | | | | | | | | My recent patch converting usb-storage to use usb_reset_composite_device() added a bug, a race between reset and disconnect. It was necessary to drop the private lock while executing a reset, and if a disconnect occurs at that time it will cause a crash.

| | | | | | | | | | | | | | tiny things This is a new driver for the Cypress CY7C63xxx mirco controller series. It currently supports the pre-programmed CYC63001A-PC by AK Modul-Bus GmbH.

* [PATCH] USB: au1200: EHCI and OHCI fixesDaniel Mack2006-07-122-13/+11
| | | | | | | | | | | | | | | | | | | | I received an DBAU1200 eval kit from AMD a few days ago and tried to enable the USB2 port, but the current linux-2.6 GIT did not even compile with CONFIG_SOC_1200, CONFIG_SOC_AU1X00, CONFIG_USB_EHCI and CONFIG_USB_OHCI set. Furthermore, in ehci-hcd.c, platform_driver_register() was called with an improper argument of type 'struct device_driver *' which of course ended up in a kernel oops. How could that ever have worked on your machines? Anyway, here's a trivial patch that makes the USB subsystem working on my board for both OHCI and EHCI. It also removes the /* FIXME use "struct platform_driver" */.

As of this kernel the AHCI driver grabs the controller and rams it into AHCI mode losing the PATA ports and making CD drives and the like vanish. The all-generic-ide option fails because the AHCI driver grabbed the PCI device and reconfigured it. To fix this three things are needed. #1 We must put the chip into dual function mode #2 The AHCI driver must grab only function 0 (already in your rc1 tree) #3 Something must grab the PATA ports The attached patch is the minimal risk edition of this. It puts the chip into dual function mode so that AHCI will grab the SATA ports without losing the PATA ports. To keep the risk as low as possible the third patch adds the PCI identifiers for the PATA port and the FN check to the ide-generic driver. There is a more featured jmicron driver on its way but that adds risk and the ide-generic support is sufficient to install and run a system. The actual chip setup done by the quirk is the precise setup recommended by the vendor. (The JMB368 appears only in the ide-generic entry as it has no AHCI so does not need the quirk) Signed-off-by: Alan Cox <alan@redhat.com> Acked-by: Jeff Garzik <jgarzik@pobox.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | [PATCH] Make cpu_relax() imply barrier() on all archesChase Venters2006-07-127-7/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | During the recent discussion of taking 'volatile' off of the spinlock, I noticed that while most arches #define cpu_relax() such that it implies barrier(), some arches define cpu_relax() to be empty. This patch changes the definition of cpu_relax() for frv, h8300, m68knommu, sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().

At a minimum we need the patch below to save/restore hardirq state.
