However, stat() stores the size of the file as off_t, which means that the following check in tracecmd_write_cpu_data() will not work with large enough files whose size fit in an off_t, but not in an int ret = stat(cpu_data_files[i], &st); if (ret < 0) { tracecmd_warning("can not stat '%s'", cpu_data_files[i]); break; } ... data[i].size = st.st_size; due to the error being in the actual assignment to data[i].size. This int value (potentially negative) gets later assigned to the file_size field of struct data_file_write in out_write_cpu_data() and later compared to the variable read_size, which can lead to the following error: libtracecmd: Invalid argument did not match size of 3451486208 to -843481088 Signed-off-by: Jaroslav Jindrak --- lib/trace-cmd/include/trace-cmd-local.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/trace-cmd/include/trace-cmd-local.h b/lib/trace-cmd/include/trace-cmd-local.h index ebd6f152..a6b39344 100644 --- a/lib/trace-cmd/include/trace-cmd-local.h +++ b/lib/trace-cmd/include/trace-cmd-local.h @@ -93,7 +93,7 @@ out_add_buffer_option(struct tracecmd_output *handle, const char *name, struct cpu_data_source { int fd; - int size; + off_t size; off_t offset; };
