gradm - Administration program for the grsecurity RBAC system
gradm [ -E ] [ -R ] [ -C ] [ -F ] [ -L <logfile> ] [ -O <filename|stream> ] [ -M <filename|uid> ] [ -D ] [ -P [rolename] ] [ -a <rolename> ] [ -n <rolename> ] [ -p <rolename> ] [ -u ] [ -V ] [ -h ] [ -v ]
gradm is the userspace RBAC parsing and authentication program for grsecurity grsecurity aims to be a complete security system for Linux 2.4. gradm performs several tasks for the RBAC system including authenticated via a password to the kernel and parsing rules to be passed to the kernel.
All options to gradm are mutually exclusive, except for -L and -O. -E Enable the RBAC system -R Reload the RBAC system (only valid while in admin mode) -C Perform a check of the RBAC policy, running the same analysis against it that is performed when enabling. -F Toggle full learning mode. If used only with -L, it enables the RBAC system in full learning mode. If used with -L and -O, it parses the full learning logs and generates a complete ruleset. -M <filename|uid> Remove an execution ban on a given uid or filename that has been put in place by the RES_CRASH resource restriction of the RBAC system. -L <logfile> Parses the learning logs. Accepts an argument which specifies the logfile to scan for the learning logs. If "-" is specified as the logfile, stdin will be used as the learning log. This option can be used with -E, -O, or -F. -O <filename|stream> Specifies output mode. Requires a single argument that can be "stdout", "stderr", or a regular file. Only used with -L or -F. -D Disable the RBAC system -P [rolename] Without an argument, it sets the password for administering the RBAC system. With a role name as an argument, it sets the password for that given special role. -a <rolename> Authenticate to a special role that requires a password. -n <rolename> Authenticate to a special role that does not require a password. -p <rolename> Authenticate through PAM to a special role. -u Removes yourself from your current special role, reverting back to the normal role selection. To be used, for instance, for logging out of an admin role without exiting your shell. -V Displays verbose policy statistics when enabling the RBAC system or checking the RBAC policy. Can only be used with -C, -E, or -F -L <filename> -h Display help information -v Print version information and exit
