Lennart Poettering ffc227c956 selinux: remove anything PID1-specific from selinux-access.[ch] so that we can reuse it in logind 2012-10-02 17:56:54 -04:00
Lennart Poettering cad45ba11e selinux: rework selinux access check logic
a) Instead of parsing the bus messages inside of selinux-access.c
simply pass everything pre-parsed in the functions

b) implement the access checking with a macro that resolves to nothing
on non-selinux builds

c) split out the selinux checks into their own sources
selinux-util.[ch]

d) this unifies the job creation code behind the D-Bus calls
Manager.StartUnit() and Unit.Start().

Daniel J Walsh e2417e4143 selinux: add bus service access control
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

This patch adds the ability to look at the calling process that is trying to
do dbus calls into systemd, then it checks with the SELinux policy to see if
the calling process is allowed to do the activity.

The basic idea is we want to allow NetworkManager_t to be able to start and
stop ntpd.service, but not necessarly mysqld.service.

Similarly we want to allow a root admin webadm_t that can only manage the
apache environment.  systemctl enable httpd.service, systemctl disable
iptables.service bad.

To make this code cleaner, we really need to refactor the dbus-manager.c code.
 This has just become a huge if-then-else blob, which makes doing the correct
check difficult.
