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
# newrole -r sysadm_r
# id -Z

Changing sensitivity only:
# id -Z
# newrole -l Secret
# id -Z

Changing sensitivity and clearance:
# id -Z
# newrole -l Secret-Secret
# id -Z

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/securetty_types - securetty types for level changes
/etc/selinux/newrole_pam.conf - optional mapping of commands to separate pam service names
