Hello
I tried to execute:
for i in `seinfo -aexec_type -x`; do
if [ $i = "exec_type" ]; then
continue;
fi
sesearch --allow -s domain -t $i -c file -p relabelto | awk
'/allow/{print $2}' >> domains.tmp
done;
cat domains.tmp | sort | uniq -c
This is the result:
552 prelink_t
1 pulseaudio_t
552 restorecond_t
552 rpm_script_t
552 rpm_t
552 setfiles_mac_t
552 setfiles_t
4 seunshare_t
4 staff_t
552 sysadm_t
1 unconfined_t
1 useradd_t
4 user_t
14 webadm_t
OK, i hope this is the correct list (for now, until the setools bug will be
solved).
Another aspect of the policy which i need to understand is the list of domains
which are allowed to modify the file labelling behaviour, when it is enforced.
For example, when i enter the sysadm_t domain, i can disable the enforcement
or i can load a custom policy module that add new rules. What are the criteria
to pass to the sesearch tool in order to get the correct list?
Thanks.
