This adds support for CONFIG_RESTRICTED_CONSOLE_COMMANDS. If the
appropriate options are configured, restricted commands can be
prevented from running.
Nothing in this CL actually uses that, but it works if you turn
it on.
BUG=chrome-os-partner:55322
BRANCH=none
TEST=make buildall, test on Cr50 hardware
I also tested it manually. If you add this to board.h:
#define CONFIG_CONSOLE_COMMAND_FLAGS
#define CONFIG_RESTRICTED_CONSOLE_COMMANDS
#define CONFIG_CONSOLE_COMMAND_FLAGS_DEFAULT CMD_FLAG_RESTRICTED
and this to board.c:
static int restricted_state;
int console_is_restricted(void)
{
return restricted_state;
}
static int command_lock(int argc, char **argv)
{
int enabled;
if (argc > 1) {
if (!parse_bool(argv[1], &enabled))
return EC_ERROR_PARAM1;
restricted_state = enabled;
}
ccprintf("The restricted console lock is %s\n",
restricted_state ? "enabled" : "disabled");
return EC_SUCCESS;
}
DECLARE_CONSOLE_COMMAND_FLAGS(lock, command_lock,
"[<BOOLEAN>]",
"Get/Set the restricted console lock",
0); /* no restrictions */
then you can use the "lock" command to enable and disable every
other console command except for it and "help".
