Since commit 0f036bf4b87e ("env: Warn on force access if ENV_ACCESS_IGNORE_FORCE set") a warning message is displayed when setenv -f is used WITHOUT CONFIG_ENV_ACCESS_IGNORE_FORCE, but the variable is set anyway, resulting in lots of log pollution.
env_flags_validate() returns 0 if the access is accepted, or non zero if it is refused.
So the original code #ifndef CONFIG_ENV_ACCESS_IGNORE_FORCE if (flag & H_FORCE) return 0; #endif
was correct, it returns 0 (accepts the modification) if forced UNLESS IGNORE_FORCE is set (in which case access checks in the following code are applied). The broken patch just added a printf to the force accepted case.
To obtain the intent of the patch we need this: if (flag & H_FORCE) { #ifdef CONFIG_ENV_ACCESS_IGNORE_FORCE printf("## Error: Can't force access to "%s"\n", name); #else return 0; #endif }
Fixes: 0f036bf4b87e ("env: Warn on force access if ENV_ACCESS_IGNORE_FORCE set")
