2015-03-09iio: Move iio userspace applications out of stagingRoberta Dobrescu1-71/+0
This patch moves iio userspace applications out of staging, to tools/iio/ and adds a Makefile in order to compile them easily. It also adds tools/iio/ to MAINTAINERS file. Signed-off-by: Roberta Dobrescu <roberta.dobrescu@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-03-09staging: iio: Documentation: Introduce iio_utils.cRoberta Dobrescu1-638/+26
This patch removes inline functions from iio_utils.h in order to clean the code. iio_utils.c contains the implementation of the functions used by iio_event_monitor.c, lsiio.c or generic_buffer.c and iio_utils.h contains the declarations of these functions. Since iio_utils.h is modified, generic_buffer.c and iio_event_monitor.c must include stdlib.h.

2014-01-01iio: Fix a buffer overflow in iio_utils.h example codeCraig Markwardt1-3/+3
This was originally reported by Craig Markwardt on Zubair Lutfullah's blog and Zubair forwarded it to linux-iio@vger.kernel.org. No email address known. The code first counted the number of enabled channels, then created an array to hold information about them. The code that filled this array then stored whether a given element was enabled inside the array. Curriously this element was never used. Craig's patch added a local temporary variable to avoid the buffer overrun. Jonathan then removed the original enabled element of the structure as it was not needed at all.

2011-03-09Staging: IIO: Documentation: iio_utils: fix channel array generation.Michael Hennerich1-23/+33
The previous implementation flawed, in case some channels are not enabled. The sorted array would then include channel information of disabled channels, And misses the enabled ones, when the count is reached. More troublesome, the loop would not even terminate. The fix is twofold: First we skip channels that are not enabled. Then we use a tested bubble sort algorithm to sort the array. Since we already allocated exactly the number of bytes we need. We can exercise bubble sort on the original memory. In all cases I've seen, the array is already sorted, so this sort terminates immediately. Changes since V1: Fix coding style issues.

2011-02-28IIO: Documentation: iio_utils: Prevent buffer overflowMichael Hennerich1-1/+3
The first part of build_channel_array()identifies the number of enabled channels. Further down this count is used to allocate the ci_array. The next section parses the scan_elements directory again, and fills ci_array regardless if the channel is enabled or not. So if less than available channels are enabled ci_array memory is overflowed. This fix makes sure that we allocate enough memory. But the whole approach looks a bit cumbersome to me. Why not allocate memory for MAX_CHANNLES, less say 64 (I never seen a part with more than that channels). And skip the first part entirely.
