Florian Fainelli 1584dc3da7 tools/thermal: Fix possible path truncations ... [ Upstream commit 6c58cf40e3 ] A build with -D_FORTIFY_SOURCE=2 enabled will produce the following warnings: sysfs.c:63:30: warning: '%s' directive output may be truncated writing up to 255 bytes into a region of size between 0 and 255 [-Wformat-truncation=] snprintf(filepath, 256, "%s/%s", path, filename); ^~ Bump up the buffer to PATH_MAX which is the limit and account for all of the possible NUL and separators that could lead to exceeding the allocated buffer sizes.
