Some USB devices do have a configuration 0, in contravention of the USB spec. Normally 0 is supposed to indicate that a device is unconfigured. While we can't change what the device is doing, we can change usbcore. This patch (as852) allows usb_set_configuration() to accept a config value of -1 as indicating that the device should be unconfigured. The request actually sent to the device will still contain 0 as the value. But even if the device does have a configuration 0, dev->actconfig will be set to NULL and dev->state will be set to USB_STATE_ADDRESS. Without some sort of special-case handling like this, there is no way to unconfigure these non-compliant devices. Signed-off-by:

A SET_LINE_CODING control request should return a zero length packet as an ACK to the host, during the status phase of a USB transaction. The return value of gs_setup_class() is treated as the number of bytes to write in the status phase of the control request, by gs_setup(). For this case, the value returned by gs_setup_class should be zero for SET_LINE_CODING but, right now, appears to be sizeof(struct usb_cdc_line_coding). However, if after doing the memcpy of the line coding descriptor we set the variable "ret" to be zero, we should return the appropiate ZLP to the host as an ACK in the status phase of the control request. I've tested this out using Linux as both host and slave and confirmed that the following small change fixes the spurious return of sizeof(struct usb_cdc_line_coding)/wLength bytes in the status phase of a USB_CDC_REQ_SET_LINE_CODING request. It's not a huge bug but, it is worth fixing. Signed-off-by:

Device will not work as a mass storage device without US_FL_IGNORE_RESIDUE. I bought this mp3 player that takes SD cards here http://www.aiptek.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=AX4&Category_Code=MP3&Store_Code=AS I can provide the errors in dmesg, if necessary, but this flag was determined as necessary by doing a quick google on the errors that were shown in dmesg.

there's a USB mass storage device which exists in two version. One reports the correct size and the other does not. Apart from that they are identical and cannot be told apart. Here's a heuristic based on the empirical finding that drives have even sizes. Signed-off-by:

as the skeleton driver was made ready for autosuspend a race condition was introduced. The reference to get device must be gotten before the autosuspend counter is upped, as this operation may sleep, dropping BKL. Dropping BKL means that the pointer to the device may become invalid. Here's the fix. Signed-off-by:

This patch (as847) makes some small changes to the hub driver's suspend method: For root hubs, the status URB should be unlinked and other activity stopped _before_ the bus_suspend method is called. The test for hdev->bus being NULL has been removed, since it can never succeed. Signed-off-by:

I added two fields to struct usb_serial_port to keep track of the throttle state. Other usb-serial drivers typically use private data for such things, but the generic driver can not really do that because some of its code is also used by other drivers (which may have their own private data needs). As it is, I am not sure that this patch is useful in all scenarios. It is certainly helpful for low-bandwidth devices that can hold their data in response to throttling. But for devices that pump data in real-time as fast as possible (webcam, A/D converter, etc), throttling may actually cause more data loss.

A simple driver to turn on the charging capability of a USB BlackBerry device when it is plugged into the machine. It does not bind to the device, so all userspace programs can still sync properly with it. Note, if CONFIG_USB_SUSPEND is enabled, it can play havoc with this device as the power to the port will be shut down. This device id will have to be added to the global blacklist table when it is created. Signed-off-by: -

When NFSD receives a write request, the data is typically in a number of 1448 byte segments and writev is used to collect them together. Unfortunately, generic_file_buffered_write passes these to the filesystem one at a time, so an e.g. 32K over-write becomes a series of partial-page writes to each page, causing the filesystem to have to pre-read those pages - wasted effort. generic_file_buffered_write handles one segment of the vector at a time as it has to pre-fault in each segment to avoid deadlocks. When writing from kernel-space (and nfsd does) this is not an issue, so generic_file_buffered_write does not need to break and iovec from nfsd into little pieces. This patch avoids the splitting when get_fs is KERNEL_DS as it is from NFSd. This issue was introduced by commit 6527c2bdAcked-by:

We're inserting deny's between some ACEs in order to enforce posix draft acl semantics which prevent permissions from accumulating across entries in an acl. That's fine, but we're doing that by inserting a deny after *every* allow, which is overkill. We shouldn't be adding them in places where they actually make no difference. Also replaced some helper functions for creating acl entries; I prefer just assigning directly to the struct fields--it takes a few more lines, but the field names provide some documentation that I think makes the result easier understand.

Return just the effective permissions, and forget about the mask. It isn't worth the complexity.
