TOMOYO wants to use /proc/self/ rather than /proc/$PID/ if $PID matches current thread's process ID in order to prevent current thread from accessing other process's information unless needed. But since procfs can be mounted on various locations (e.g. /proc/ /proc2/ /p/ /tmp/foo/100/p/ ), TOMOYO cannot tell that whether the numeric part in the string returned by __d_path() represents process ID or not. Therefore, to be able to convert from $PID to self no matter where procfs is mounted, this patch changes pathname representations for filesystems which do not support rename() operation (e.g. proc, sysfs, securityfs). Examples: /proc/self/mounts => proc:/self/mounts /sys/kernel/security/ => sys:/kernel/security/ /dev/pts/0 => devpts:/0 Signed-off-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Signed-off-by: James Morris <jmorris@namei.org> |
