ensubs (enter_subsystem) -- Enter a protected subsystem.
usage: ensubs subsystem_name
DESCRIPTION
ensubs is used to enter a protected subsystem at shell command level.
Once in the subsystem, the subs command can be used to create new
managers for the subsystem or to seal data objects so that only managers
of the subsystem can operate on them. Also, subsystem managers can be
debugged conveniently in this mode using debug, and protected data
objects can be examined. Note, however, that access to protected objects
requires prior use of the subs -up command.
The access control list on the file /sys/subsys/subsystem_name determines
who can enter the subsystem subsystem_name: whoever has read and execute
rights to it can enter the subsystem. Usually, this capability should be
restricted to the creators of the subsystem or to the system
administrator.
ARGUMENTS
subsystem_name (required)
Specify name of subsystem to be entered. The shell
searches the directory /sys/subsys for the file specified.
