Previous Comments: ------------------------------------------------------------------------ [2005-01-25 04:38:37] elod at itfais dot com Description: ------------ The implementation of dio_tcsetattr misuses the tcsetattr() function call for setting termios parameters on a descriptor. It fills an uninitialized stack local termios structure with parameters gleened from input to the dio_tcsetattr() function call while leaving all other paramters uninitialized. This can (and does) lead to unpredictable behavior on the device when default settings are overwritten with garbage. The correct way to set termio structure information is to first _get_ the current termios settings (tcgetattr) on the device, then modifying only the flags necessary, and then setting the modified termios with tcsetattr(). Following is a diff of ext/dio.c between the distribution version and my modified (and fixed) version: 598a599,600 > memset(&newtio, 0, sizeof(newtio)); > tcgetattr(f->fd, &newtio); ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31684&edit=1
