Description John Haxby 2003-02-13 14:26:01 UTC
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021212 Description of problem: I wanted to bind-mount a directory read-only so that I could safely make it visible through ftp, but, alas, it isn't read-only 00 it looks as though the read-only flag is ignored even though it appears in the output of "mount". Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. mkdir /tmp/xxx /tmp/yyy 2. mount -o ro,bind /tmp/xxx /tmp/yyy 3. touch /tmp/yyy/this-should-not-work Actual Results: Each command reports everything OK and the file is created. Expected Results: I was rather hoping to get a "read-only filesystem" error. Additional info: "mount | grep /tmp" shows /tmp/xxx on /tmp/yyy type none (ro,bind) which rather suggests that /tmp/yyy should be read-only, but "grep /tmp /proc/mounts" shows /dev/sheep/root /tmp/yyy reiserfs rw 0 0 which rather suggests it doesn't. I have an ext3 bind as well which exhibits the same characteristics. This is with kernel-2.4.18-24.8.0 and mount-2.11r-10. This may well be a combination between a bug and an enhancement request if the kernel doesn't support a read-only bind.
