Matti Vaittinen 4e208294de tools: iio: iio_generic_buffer: Fix read size ... [ Upstream commit 7c919b619b ] When noevents is true and small buffer is used the allocated memory for holding the data may be smaller than the hard-coded 64 bytes. This can cause the iio_generic_buffer to crash. Following was recorded on beagle bone black with v6.0 kernel and the digit fix patch: https://lore.kernel.org/all/Y0f+tKCz+ZAIoroQ@dc75zzyyyyyyyyyyyyycy-3.rev.dnainternet.fi/ using valgrind; ==339== Using Valgrind-3.18.1 and LibVEX; rerun with -h for copyright info ==339== Command: /iio_generic_buffer -n kx022-accel -T0 -e -l 10 -a -w 2000000 ==339== Parent PID: 307 ==339== ==339== Syscall param read(buf) points to unaddressable byte(s) ==339== at 0x496BFA4: read (read.c:26) ==339== by 0x11699: main (iio_generic_buffer.c:724) ==339== Address 0x4ab3518 is 0 bytes after a block of size 160 alloc'd ==339== at 0x4864B70: malloc (vg_replace_malloc.c:381) ==339== by 0x115BB: main (iio_generic_buffer.c:677) Fix this by always using the same size for reading as was used for data storage allocation.
