strncpy() is deprecated for NUL-terminated destination buffers and must be replaced by strscpy().
See issue: https://github.com/KSPP/linux/issues/90 Signed-off-by: Devaansh Kumar <devaanshk...@gmail.com> --- Changes since v4: - Removed unnecessary sizeof(stack_trace_filter_buf) in strscpy Changes since v3: - Refactored code to compare length with str_has_prefix in a single line Changes since v2; - Removed unnecessary string.h header file inclusion Changes since v1: - Moved from memcpy() to strscpy() kernel/trace/trace_stack.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/trace/trace_stack.c b/kernel/trace/trace_stack.c index 14c6f272c4d8..4c349db381cb 100644 --- a/kernel/trace/trace_stack.c +++ b/kernel/trace/trace_stack.c @@ -542,7 +542,7 @@ static __init int enable_stacktrace(char *str) int len; if ((len = str_has_prefix(str, "_filter="))) - strncpy(stack_trace_filter_buf, str + len, COMMAND_LINE_SIZE); + strscpy(stack_trace_filter_buf, str + len); stack_tracer_enabled = 1; return 1; -- 2.49.0
