staging: tidspbridge: request dmtimer clocks on init

2011-12-14T00:12:06Z

Given that dm timer framework doesn't support request of clocks by soft | hard irqs because some recent changes, tidspbridge needs to request its clocks on init and enable/disable them on demand. This was first seen on 3.2-rc1. Signed-off-by: Omar Ramirez Luna Signed-off-by: Greg Kroah-Hartman

Staging: comedi: fix integer overflow in do_insnlist_ioctl()

2011-11-27T19:38:45Z

There is a potential integer overflow in do_insnlist_ioctl() if userspace passes in a large insnlist.n_insns. The call to kmalloc() would allocate a small buffer, leading to a memory corruption. The bug was reported by Dan Carpenter and Haogang Chen . The patch was suggested by Ian Abbott and Lars-Peter Clausen . Reported-by: Dan Carpenter Reported-by: Haogang Chen .

Staging: comedi: integer overflow in do_insnlist_ioctl()

2011-11-27T02:34:15Z

There is an integer overflow here that could cause memory corruption on 32 bit systems. insnlist.n_insns could be a very high value size calculation for kmalloc() could overflow resulting in a smaller "insns" than expected. In the for (i = 0; i < insnlist.n_insns; i++) {... loop we would read past the end of the buffer, possibly corrupting memory as well. Signed-off-by: Dan Carpenter Signed-off-by: Greg Kroah-Hartman

Staging: comedi: fix mmap_count

2011-11-27T02:34:14Z

In comedi_fops, mmap_count is decremented at comedi_vm_ops->close but it is not incremented at comedi_vm_ops->open. This may result in a negative counter. The patch introduces the open method to keep the counter consistent. The bug was triggerd by this sample code: mmap(0, ...., comedi_fd); fork(); exit(0); Acked-by: Alessandro Rubini Signed-off-by: Federico Vaga Cc: stable Signed-off-by: Greg Kroah-Hartman
