Hi guys,
I started creating my policy module for the eggdrop irc bot. I am
getting stuck on simple task. I want to add a transition from
unconfined_t to eggdrop_t when I run a eggdrop_exec_t file.
This is what I have:
policy_module(eggdrop, 1.0.0)
########################################
## Declarations#gen_require(`
type unconfined_t;
')
type eggdrop_t;
type eggdrop_exec_t;
application_executable_file(eggdrop_exec_t)
This is not required, it is in "application_domain() which you should
call. lack of application_domain(eggdrop_t, eggdrop_exec_t) is whats
causing the constraint violation.
Also allow the unconfined_r role the eggdrop_t domain:
role unconfined_r types eggdrop_t;
(you also will need to require "role unconfined_r;")
type eggdrop_conf_t;
files_config_file(eggdrop_conf_t)
corenet_tcp_connect_ircd_port(eggdrop_t)
corenet_tcp_sendrecv_ircd_port(eggdrop_t)
domain_auto_trans(unconfined_t,eggdrop_exec_t,eggdrop_t)
Better use domtrans_pattern() instead of domain_auto_trans. It better
fits the requirements:
domtrans_pattern(unconfined_t, eggdrop_exec_t, eggdrop_t)
so a basic standard template to start is:
- ----------->8--------------
policy_module(eggdrop, 1.0.0)
gen_require(`
type unconfined_t;
role unconfined_r;
')
type eggdrop_t;
type eggdrop_exec_t;
application_domain(eggdrop_t, eggdrop_exec_t)
role unconfined_r types eggdrop_t;
type eggdrop_etc_t;
files_config_file(eggdrop_etc_t)
domtrans_pattern(unconfined_t, eggdrop_exec_t, eggdrop_t
- -------------8<------------
This is what I get when I try to load this policy module:
lrfurtado:~/selinux/eggdrop# make load
Loading default modules: eggdrop
/usr/sbin/semodule -i eggdrop.pp
libsepol.check_assertion_helper: neverallow violated by allow
unconfined_t eggdrop_t:process { transition };
libsemanage.semanage_expand_sandbox: Expand module failed
/usr/sbin/semodule: Failed!
make: *** [tmp/loaded] Error 1
lrfurtado:~/selinux/eggdrop#
What's the proper way of accomplishing this?
