From 9636bf8b2e319c0f43453f71131ba70856571d05 Mon Sep 17 00:00:00 2001 From: Martin Fuzzey Date: Mon, 11 Jan 2021 11:27:20 +0100 Subject: [PATCH] env: Fix warning when forcing environment without ENV_ACCESS_IGNORE_FORCE 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") Signed-off-by: Martin Fuzzey --- env/flags.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/env/flags.c b/env/flags.c index df4aed26b2..e3e833c433 100644 --- a/env/flags.c +++ b/env/flags.c @@ -563,12 +563,13 @@ int env_flags_validate(const struct env_entry *item, const char *newval, return 1; #endif -#ifndef CONFIG_ENV_ACCESS_IGNORE_FORCE if (flag & H_FORCE) { +#ifdef CONFIG_ENV_ACCESS_IGNORE_FORCE printf("## Error: Can't force access to \"%s\"\n", name); +#else return 0; - } #endif + } switch (op) { case env_op_delete: if (item->flags & ENV_FLAGS_VARACCESS_PREVENT_DELETE) {
