USB: Do not pass negative length to snoop_urb()

2011-03-23T20:14:16Z

When `echo Y > /sys/module/usbcore/parameters/usbfs_snoop` and usb_control_msg() returns error, a lot of kernel memory is dumped to dmesg until unhandled kernel paging request occurs. Signed-off-by: Michal Sojka Cc: stable@kernel.org Signed-off-by: Greg Kroah-Hartman

BKL: remove extraneous #include

2010-11-17T16:59:32Z

The big kernel lock has been removed from all these files at some point, leaving only the #include. Remove this too as a cleanup. Signed-off-by: Arnd Bergmann Signed-off-by: Linus Torvalds

usb: core: fix information leak to userland

2010-11-11T15:14:07Z

Structure usbdevfs_connectinfo is copied to userland with padding byted after "slow" field uninitialized. It leads to leaking of contents of kernel stack memory. Signed-off-by: Vasiliy Kulikov Cc: stable Signed-off-by: Greg Kroah-Hartman

USB-BKL: Convert usb_driver ioctl to unlocked_ioctl

2010-08-10T21:35:35Z

And audit all the users. None needed the BKL. That was easy because there was only very few around. Tested with allmodconfig build on x86-64 Signed-off-by: Andi Kleen Cc: Arnd Bergmann From: Andi Kleen

USB: make hcd.h public (drivers dependency)

2010-05-20T20:21:30Z

The usbcore headers: hcd.h and hub.h are shared between usbcore, HCDs and a couple of other drivers (e.g. USBIP modules). So, it makes sense to move them into a more public location and to cleanup dependency of those modules on kernel internal headers. This patch moves hcd.h from drivers/usb/core into include/linux/usb/ Signed-of-by: Eric Lescouet Cc: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: fix usbfs regression

2010-03-19T14:24:02Z

This patch (as1352) fixes a bug in the way isochronous input data is returned to userspace for usbfs transfers. The entire buffer must be copied, not just the first actual_length bytes, because the individual packets will be discontiguous if any of them are short.

USB: usbfs_snoop: add data logging back in

2010-03-02T22:54:37Z

Uses the new snoop function from commit 4c6e8971cbe0148085, but includes the buffer data where appropriate, as before. Signed-off-by: Chris Frey Signed-off-by: Greg Kroah-Hartman

USB: BKL removal from ioctl path of usbfs

2010-03-02T22:54:32Z

Total removal from the ioctl code path except for the outcall to external modules. Locking is ensured by the normal locks of usbfs. Signed-off-by: Oliver Neukum Cc: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: Reduce scope of BKL in usb ioctl handling

2010-03-02T22:54:24Z

This pushes BKL down in ioctl handling and drops it for some important ioctls Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman

USB: Remove BKL from lseek implementations

2010-03-02T22:54:23Z

Replace it by mutex_lock(&file->f_dentry->d_inode->i_mutex); following the example of the generic method Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman
