drivers/staging/comedi/comedi_fops.c: add missing vfree

2012-06-01T07:12:54+00:00

commit abae41e6438b798e046d721b6ccdd55b4a398170 upstream. aux_free is freed on all other exits from the function. By removing the return, we can benefit from the vfree already at the end of the function. Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman

Staging: comedi: fix signal handling in read and write

2011-12-09T16:52:40+00:00

commit 6a9ce6b654e491981f6ef7e214cbd4f63e033848 upstream. After sleeping on a wait queue, signal_pending(current) should be checked (not before sleeping). Acked-by: Alessandro Rubini Signed-off-by: Federico Vaga Signed-off-by: Greg Kroah-Hartman

Staging: comedi: fix mmap_count

2011-12-09T16:52:40+00:00

commit df30b21cb0eed5ba8a8e0cdfeebc66ba8cde821d upstream. 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 Signed-off-by: Greg Kroah-Hartman

staging: comedi: fix oops for USB DAQ devices.

2011-12-09T16:52:40+00:00

commit 3ffab428f40849ed5f21bcfd7285bdef7902f9ca upstream. This fixes kernel oops when an USB DAQ device is plugged out while it's communicating with the userspace software. Signed-off-by: Bernd Porr Signed-off-by: Greg Kroah-Hartman

staging: comedi: fix infoleak to userspace

2011-08-05T04:58:31+00:00

commit 819cbb120eaec7e014e5abd029260db1ca8c5735 upstream. driver_name and board_name are pointers to strings, not buffers of size COMEDI_NAMELEN. Copying COMEDI_NAMELEN bytes of a string containing less than COMEDI_NAMELEN-1 bytes would leak some unrelated bytes. Signed-off-by: Vasiliy Kulikov Signed-off-by: Greg Kroah-Hartman

Staging: comedi: fix build breakages on some platforms

2011-06-27T21:43:34+00:00

Some platforms do not have virt_to_bus(), so properly depend on CONFIG_VIRT_TO_BUS for the Comedi drivers that need this function. Reported-by: Stephen Rothwell Signed-off-by: Greg Kroah-Hartman

Staging: Comedi: Build only on arches providing PAGE_KERNEL_NOCACHE

2011-06-27T21:19:20+00:00

On architectures that don't define PAGE_KERNEL_NOCACHE, the Comedi driver turns into tragedy: CC [M] drivers/staging/comedi/drivers.o drivers/staging/comedi/drivers.c: In function ‘comedi_buf_alloc’: drivers/staging/comedi/drivers.c:505:41: error: ‘PAGE_KERNEL_NOCACHE’ undeclared (first use in this function) drivers/staging/comedi/drivers.c:505:41: note: each undeclared identifier is rep orted only once for each function it appears in make[3]: *** [drivers/staging/comedi/drivers.o] Error 1 Restrict the driver to only those architectures that define PAGE_KERNEL_NOCACHE. PAGE_KERNEL_NOCACHE is a kludge - some system architectures such as SGI IP27 are even uable to offer uncached operation - at least in the way an unwitting driver might assume. I haven't looked in details how the driver is using the area vmaped with PAGE_KERNEL_NOCACHE but maybe doing it XFS-style using cached memory and the flush_kernel_vmap_range / invalidate_kernel_vmap_range APIs in conjunction with the DMA API is a practical alternative.

comedi vmk80xx: support comedi auto-configuration

2011-05-18T21:32:07+00:00

Add support for automatically associating a vmk8055 device with a comedi device (previously the user had to use comedi_num_legacy_minors to reserve device slots and then associate them with vmk8055 devices using comedi_config). Tested on multiple K8055s, but not on K8061s. Signed-off-by: J. Ali Harlow Signed-off-by: Greg Kroah-Hartman

comedi vmk80xx: support bits instruction

2011-05-18T21:32:06+00:00

Calling comedi_dio_bifield2() returns EBUSY permanently. Implementing the insn_bits call fixes the problem and is good in its own right since one can then read and write to all the digitial lines at the same time. Tested on a K8055, but not on a K8061.
