NEWROLE(1) NSA NEWROLE(1)
newrole - run a shell with a new SELinux role
newrole [-r|--role] ROLE [-t|--type] TYPE [-l|--level]
[-p|--preserve-environment] LEVEL [-- [ARGS]...]
Run a new shell in a new context. The new context is derived from
the old context in which newrole is originally executed. If the -r
or --role option is specified, then the new context will have the
role specified by ROLE. If the -t or --type option is specified,
then the new context will have the type (domain) specified by TYPE.
If a role is specified, but no type is specified, the default type is
derived from the specified role. If the -l or --level option is
specified, then the new context will have the sensitivity level
specified by LEVEL. If LEVEL is a range, the new context will have
the sensitivity level and clearance specified by that range. If the
-p or --preserve-environment option is specified, the shell with the
new SELinux context will preserve environment variables, otherwise a
new minimal enviroment is created.
Additional arguments ARGS may be provided after a -- option, in which
case they are supplied to the new shell. In particular, an argument
of -- -c will cause the next argument to be treated as a command by
most command interpreters.
If a command argument is specified to newrole and the command name is
found in /etc/selinux/newrole_pam.conf, then the pam service name
listed in that file for the command will be used rather than the
normal newrole pam configuration. This allows for per-command pam
configuration when invoked via newrole, e.g. to skip the interactive
re-authentication phase.
The new shell will be the shell specified in the user's entry in the
/etc/passwd file.
The -V or --version shows the current version of newrole
Changing role:
# id -Z
staff_u:staff_r:staff_t:SystemLow-SystemHigh
# newrole -r sysadm_r
# id -Z
staff_u:sysadm_r:sysadm_t:SystemLow-SystemHigh
Changing sensitivity only:
# id -Z
staff_u:sysadm_r:sysadm_t:Unclassified-SystemHigh
# newrole -l Secret
# id -Z
staff_u:sysadm_r:sysadm_t:Secret-SystemHigh
Changing sensitivity and clearance:
# id -Z
staff_u:sysadm_r:sysadm_t:Unclassified-SystemHigh
# newrole -l Secret-Secret
# id -Z
staff_u:sysadm_r:sysadm_t:Secret
Running a program in a given role or level:
# newrole -r sysadm_r -- -c "/path/to/app arg1 arg2..."
# newrole -l Secret -- -c "/path/to/app arg1 arg2..."
/etc/passwd - user account information
/etc/shadow - encrypted passwords and age information
/etc/selinux/<policy>/contexts/default_type - default types for roles
/etc/selinux/<policy>/contexts/securetty_types - securetty types for
level changes
/etc/selinux/newrole_pam.conf - optional mapping of commands to
separate pam service names
