Hi Marek,

Hi,

Based on env/Kconfig  description of this option:

config ENV_ACCESS_IGNORE_FORCE
           bool "Block forced environment operations"
           default n
           help
             If defined, don't allow the -f switch to env set override
variable
             access flags.

I would think the code should look like this:

#ifdef CONFIG_ENV_ACCESS_IGNORE_FORCE
           if (flag & H_FORCE) {
                   printf("## Error: Can't force access to \"%s\"\n", name);
                   return 1;
           }
#else
           if (flag & H_FORCE)
                  return 0;
#endif

I don't think that is right.

If you do that force update will be refused when
CONFIG_ENV_ACCESS_IGNORE_FORCE, regardless if the access would be
valid without the force

That's how I understand the option was intended to work, based on the
Kconfig help text.


Ok we are understanding different things about what it's supposed to do then.

But if everyone agrees that the option should completely disable -f
then I'm fine with that, in which case the version of the patch you
propose is good (and easier to understand).

The problem I have is with the current 0f036bf4b87e which leads to log
spam on boards that *don't* have CONFIG_ENV_ACCESS_IGNORE_FORCE set
and do use -f.

Yes, that should be fixed, one way or the other.
(in fact, can you also write a test for this case ?)
