| * param_enum: protect against invalid valuesSascha Hauer2015-08-261-2/+6
| | | | | | | | | | | | | | | | Since dev_add_param_enum is passed a pointer containing the actual value it can contain an invalid value. Protect against it so that we do not access invalid array elements. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| |/ | | | | | | | | | | | | | | | | | | | | Some character devices may perform meaningful operations in their implementation of close() -- a good example would be socfpga.c which checks if the FPGA was programmed succesfully in it's close() method -- so ignoring return value of this call may cause false positives in checking exit status for success.

This opens the way to create a fb_create_screen function which takes a struct fb_info * instead of a filename. This is suitable for the framebuffer console which already has a struct fb_info *.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | get_pixel converts a 32bit trgb color into framebuffer format. This is useful for other code aswell, so export it. Other functions in the graphics utils code use the name get/set_pixel aswell, but instead of converting data they get a pixel from the framebuffer or set a pixel on the framebuffer.

* lzo: check for length overrun in variable length encoding.Stefan Müller-Klieser2015-03-251-6/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This corresponds to kernel commit 72cf90124e87d975d0b This fix ensures that we never meet an integer overflow while adding 255 while parsing a variable length encoding. It works differently from commit 206a81c ("lzo: properly check for overruns") because instead of ensuring that we don't overrun the input, which is tricky to guarantee due to many assumptions in the code, it simply checks that the cumulated number of 255 read cannot overflow by bounding this number. The MAX_255_COUNT is the maximum number of times we can add 255 to a base count without overflowing an integer. The multiply will overflow when multiplying 255 by more than MAXINT/255. The sum will overflow earlier depending on the base count. Since the base count is taken from a u8 and a few bits, it is safe to assume that it will always be lower than or equal to 2*255, thus we can always prevent any overflow by accepting two less 255 steps. This patch also reduces the CPU overhead and actually increases performance by 1.1% compared to the initial code, while the previous fix costs 3.1% (measured on x86_64). The fix needs to be backported to all currently supported stable kernels. Reported-by: Willem Pinckaers <willem@lekkertech.net> Cc: "Don A.
