(Well unless someone is exploiting it in wild). I've definitely written at least one script before that does something along the lines of 'echo foo > /dev/fd/N'. It's not one that I remember anything else about, so perhaps its behaviour would be unaffected by forbidding this if the particular file descriptor did not originally have read-write permissions. I have a hard time believing that amongst millions of users, not one of them has a script that would be affected. Frankly, I don't understand what is particularly surprising about the fact that people can write to files with world write permissions. -- Nick Bowler, Elliptic Technologies (http://www.elliptictech.com/) -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
