Hey guys,As you might guess, I've a problem with my SELinux-policy under Fedora 9.
I created a little test application 'demo' which reads some text from stdin and writes it in a config file /etc/hackbar/config.txt.
Afterwarts, I developed a policy with types demo_t, demo_exec_t und demo_etc_t and allowed demo_exec_to to read/write demo_etc_t. Everything's fine.
For testing purposes I changed /etc/hackbar/config.txt to type etc_t which demo_exec_t shouldn't be able to access as there doesn't exist an allow demo_exec_t r/w etc_t.
[stefan localhost policy]$ ls -Z /usr/local/bin/demo-rwsr-sr-x root root system_u:object_r:demo_exec_t:s0 /usr/local/ bin/demo
[stefan localhost policy]$ ls -Z /etc/hackbar/config.txt-rwxr-xr-x root root system_u:object_r:etc_t:s0 /etc/hackbar/ config.txt
Again I ran the application but it is still allowed to change that file?!
[stefan localhost policy]$ /usr/local/bin/demo Enter text: foobar Read from file: foobarRegarding to standard UNIX permissions access should be granted as the demo-app has suid set, but shouldn't SELinux permitt access anyway in this case?
SELinux is in enforcing mode. [stefan localhost policy]$ /usr/sbin/sestatus SELinux status: enabled SELinuxfs mount: /selinux Current mode: enforcing Mode from config file: enforcing Policy version: 22 Policy from config file: targeted I'm rather confused... best regards, Stefan
