5.3. Understanding Domain Transitions: sepolicy transition
Previously, the
setrans utility was used to examine if transition between two domain or process types is possible and printed out all intermediary types that are used to transition between these domains or processes. In Red Hat Enterprise Linux 7, setrans is provided as part of the sepolicy suite and the sepolicy transition command is now used instead.
The
sepolicy transition command queries a SELinux policy and creates a process transition report. The sepolicy transition command requires two command-line arguments – a source domain (specified by the -s option) and a target domain (specified by the -t option). If only the source domain is entered, sepolicy transition lists all possible domains that the source domain can transition to. The following output does not contain all entries. The “@” character means “execute”:
If the target domain is specified,
sepolicy transition examines SELinux policy for all transition paths from the source domain to the target domain and lists these paths. The output below is not complete:
See the sepolicy-transition(8) manual page for further information about
sepolicy transition.
