WDIOC_SETTIMEOUT and WDIOC_GETTIMEOUT returned the initial timeout and not the one that was last set. Fix this by updating struct watchdog_device member 'timeout'. This is how it's supposed to be done according to Documentation/watchdog/watchdog-kernel-api.txt.This is the test case I used: #include <fcntl.h> #include <linux/watchdog.h> #include <sys/stat.h> #include <sys/types.h> #include <assert.h> #include <stdlib.h> static const int TIMEOUT = 127; int main(void) { int fd = open("/dev/watchdog", O_WRONLY); if (fd == -1) return EXIT_FAILURE; int timeout = TIMEOUT; ioctl(fd, WDIOC_SETTIMEOUT, &timeout); assert(timeout == TIMEOUT); close(fd); return EXIT_SUCCESS; } Signed-off-by: Markus Rinne <[email protected]> ---
