* spi: spidev_test: Improve decoded text part of hex dumpGeert Uytterhoeven2018-09-041-3/+3
| | | | | | | | | | | | | | - Print spaces as spaces, - Do not print characters > 126, as they will be shown as garbage in the modern UTF-8 era, - Use a normal period instead of its hexadecimal ASCII value, - Delimit the text part with pipe symbols on both sides (was left side only), without any spaces, to make it clear where the decoded text starts and ends, - Drop a useless comment.

* spi: spidev_test: add option to continuously transfer dataFrode Isaksen2017-03-211-5/+88
| | | | | | | | | | | Add option to send+recv <size> bytes with <iter> iterations and show the transfer rate every 5 seconds. Example: rate: tx 4235.2kbps, rx 4235.2kbps total: tx 4882.8KB, rx 4882.8KB Signed-off-by: Frode Isaksen <fisaksen@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* spi: spidev_test: Fix input file check when transferring fileMichal Vokáč2016-11-041-1/+1
| | | | | | | | | | Check the input file fd instead of spidev fd. The spidev fd is supposed to be OK otherwise the transfer_file() function would not be called at all.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: .../build/spidev_test-v3.15/spidev_test.c: In function ‘transfer’: .../build/spidev_test-v3.15/spidev_test.c:75:18: error: ‘_IOC_SIZEBITS’ undeclared (first use in this function) ret = ioctl(fd, SPI_IOC_MESSAGE(1), &tr); ^ Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Mark Brown <broonie@kernel.org>
* / spi: spidev_test: Fix buffer overflow in unescape()Geert Uytterhoeven2016-09-141-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | 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.

Jon Corbet requested this code moved with the last changeset, https://lkml.org/lkml/2015/3/1/144, but the patch was not applied because it missed the Makefile. Moved spidev_test, spidev_fdx and their Makefile infrastructure. Signed-off-by: Joshua Clayton <stillcompiling@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
