H A D | vfs_mount.c | diff 125340 Mon Feb 02 17:02:05 MST 2004 pjd Fix many issues related to mount/unmount: 1. Root from inside a jail was able to unmount any file system (except /). 2. Unprivileged root was able to unmount file systems mounted by privileged root (execpt /). 3. User from inside a jail was able to mount file system when sysctl vfs.usermount was set to 1. 4. User was able to mount file system when vfs.usermount was set to 1 (that's ok) and unmount it even if vfs.usermount was equal to 0 (that's not correct). Possibility from point 1 was reported by: Dariusz Kowalski <darek@76.pl> Only a part of this fix will be MFC'ed (if approved).
