spi: spidev_test: Fix buffer overflow in unescape()

2016-09-14T15:22:43+00:00

Sometimes spidev_test crashes with:

    *** Error in `spidev_test': munmap_chunk(): invalid pointer: 0x00022020 ***
    Aborted

or just

    Segmentation fault

This is due to transfer_escaped_string() miscalculating the required
size of the buffer by one byte, causing a buffer overflow in unescape().

Drop the bogus "+ 1" in the strlen() parameter to fix this.

Note that unescape() never copies the zero-terminator of the source
string, so it writes at most as many bytes as the length of the source
string.

spi: spidev_test: fix build with musl libc

2016-08-15T13:23:55+00:00

spidev.h uses _IOC_SIZEBITS directly. musl libc does not provide this macro
unless linux/ioctl.h is included explicitly. Fixes build failures like:

In file included from .../host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/sys/ioctl.h:7:0,
                 from .../build/spidev_test-v3.15/spidev_test.c:20:

  ret = ioctl(fd, SPI_IOC_MESSAGE(1), &tr);
