2010-01-20OMAP: timekeeping: time should not stop during suspendKevin Hilman
During suspend, the kernel timekeeping subsystem is shut down. Before suspend and upon resume, it uses a weak function read_persistent_clock() to determine the amount of time that elapsed during suspend. This function was not implemented on OMAP, so from the timekeeping subsystem perspective (and thus userspace as well) it appeared that no time elapsed during suspend. This patch uses the 32k sync timer as a the persistent clock. NOTE: This does *NOT* fully handle wrapping of the 32k sync timer, so more than one wrapping of the 32k sync timer during suspend may cause problems. Also note there are not interrupts when the 32k sync timer wraps, so something else has to be done.

2010-01-20e1000: enhance frame fragment detectionJesse Brandeburg
Originally From: Neil Horman <nhorman@tuxdriver.com> Modified by: Jesse Brandeburg <jesse.brandeburg@intel.com> Hey all- A security discussion was recently given: http://events.ccc.de/congress/2009/Fahrplan//events/3596.en.html And a patch that I submitted awhile back was brought up. Apparently some of their testing revealed that they were able to force a buffer fragment in e1000 in which the trailing fragment was greater than 4 bytes. As a result the fragment check I introduced failed to detect the fragement and a partial invalid frame was passed up into the network stack. I've written this patch to correct it. I'm in the process of testing it now, but it makes good logical sense to me. Effectively it maintains a per-adapter state variable which detects a non-EOP frame, and discards it and subsequent non-EOP frames leading up to _and_ _including_ the next positive-EOP frame (as it is by definition the last fragment). This should prevent any and all partial frames from entering the network stack from e1000.

2010-01-20USB: fix usbstorage for 2770:915d delivers no FATRyan May
Resolves kernel.org bug 14914. Remove entry for 2770:915d (usb digital camera with mass storage support) from unusual_devs.h. The fix triggered by the entry causes the file system on the camera to be completely inaccessible (no partition table, the device is not mountable). The patch works, but let me clarify a few things about it. All the patch does is remove the entry for this device from the drivers/usb/storage/unusual_devs.h, which is supposed to help with a problem with the device's reported size (I think). I'm pretty sure it was originally added for a reason, so I'm not sure removing it won't cause other problems to reappear. Also, I should note that this unusual_devs.h entry was present (and activating workarounds) in 2.6.29, but in that version everything works fine. Starting with 2.6.30, things no longer work.

After the device reset and re-configuration, the device and the xHCI host think they are using alternate setting 0 of all interfaces. However, the USB core keeps track of the old state, which may include non-zero alternate settings. It uses intf->cur_altsetting to keep the endpoint sysfs files for the old state across the reset. The bandwidth allocation functions need to know what the xHCI host thinks the current alternate settings are, so original patch set intf->cur_altsetting to the alternate setting 0. This caused duplicate endpoint files to be created. The solution is to not set intf->cur_altsetting before calling usb_set_interface() in usb_reset_and_verify_device(). Instead, we add a new flag to struct usb_interface to tell usb_hcd_alloc_bandwidth() to use alternate setting 0 as the currently installed alternate setting.

2010-01-20USB: add missing delay during remote wakeupAlan Stern
This patch (as1330) fixes a bug in khbud's handling of remote wakeups. When a device sends a remote-wakeup request, the parent hub (or the host controller driver, for directly attached devices) begins the resume sequence and notifies khubd when the sequence finishes. At this point the port's SUSPEND feature is automatically turned off. However the device needs an additional 10-ms resume-recovery time (TRSMRCY in the USB spec). Khubd does not wait for this delay if the SUSPEND feature is off, and as a result some devices fail to behave properly following a remote wakeup. This patch adds the missing delay to the remote-wakeup path. It also extends the resume-signalling delay used by ehci-hcd and uhci-hcd from 20 ms (the value in the spec) to 25 ms (the value we use for non-remote-wakeup resumes). The extra time appears to help some devices.

2010-01-20USB: EHCI: fix handling of unusual interrupt intervalsAlan Stern
This patch (as1320) fixes two problems related to interrupt-URB scheduling in ehci-hcd. URBs with an interval of 2 or 4 microframes aren't handled. For the time being, the patch reduces to interval to 1 uframe. URBs are constrained to have an interval no larger than 1024 frames by usb_submit_urb(). But some EHCI controllers allow use of a schedule as short as 256 frames; for these controllers we may have to decrease the interval to the actual schedule length. The second problem isn't very significant since few devices expose interrupt endpoints with an interval larger than 256 frames. But the first problem is critical; it will prevent the kernel from working with devices having interrupt intervals of 2 or 4 uframes.

2010-01-20USB: Don't use GFP_KERNEL while we cannot reset a storage deviceOliver Neukum
Memory allocations with GFP_KERNEL can cause IO to a storage device which can fail resulting in a need to reset the device. Therefore GFP_KERNEL cannot be safely used between usb_lock_device() and usb_unlock_device(). Replace by GFP_NOIO.

2010-01-20usb: serial: fix memory leak in generic driverJohan Hovold
Fix a regression introduced by commit 715b1dc01fe44537e8fce9566e4bb48d6821d84b ("USB: usb_debug, usb_generic_serial: implement multi urb write"). URB transfer buffer was never freed when using multi-urb writes. Currently the only driver enabling multi-urb writes is usb_debug.
