Title: NSH BUILTIN TASKS DO NOT WORK IN PROTECTED MODE
Description: In the PROTECTED build mode, NSH built-in commands do not
work. The current NSH builtin implementation violates the
POSIX interface layer, it calls directly into the
nuttx/binfmt logic which is not possible in the protected
mode.
Currently, support for CONFIG_BUILTIN is is disabled for
PROTECTED mode in in nuttx/binfmt/Kconfig:
config BUILTIN
bool "Support Builtin Applications"
default n
depends on (!BUILD_PROTECTED && !BUILD_KERNEL) || EXPERIMENTAL
And that disables section of the option apps/nshlib/Kconfig:
config NSH_BUILTIN_APPS
bool "Enable built-in applications"
default n
depends on BUILTIN
So if CONFIG_BUILD_PROTECTED is set, then CONFIG_BUILTIN
cannot be set. And if CONFIG_BUILTIN is not set, then
builtin applications will not be supported.
The solution appears woulld seem to be: (1) Move the problem
code out of nuttx/binfmt and into libs/binfmt so that it is
available both to the kernel code and to the application
code. And to remove the dependency on !BUILD_PROTECTED from
binfmt/Kconfig.
NOTE: NSH builtins cannot be supported under any condition
in the KERNEL build. In that build, only file-based
applications can be supported. But that is a different story.
Status: Open
Priority: Medium. Higher if you need builtin application support in
protected mode.
This really belongs in the TODO list.
